Security updates until
January 2028›July 2033
Galaxy S23: Samsung UK lists security updates until January 31, 2028. Galaxy Z Fold8 Ultra: Samsung US lists security updates until July 31, 2033. Galaxy S23 (Samsung UK spec data) · Galaxy Z Fold8 Ultra (Samsung US spec data)
What does this mean?
The month Samsung's promise of security updates for this phone runs until: the date Samsung's own page gives, or worked out from the number of years Samsung announced, counted from when the phone came out.
A phone bought later or used has fewer years left. "No longer updated" means the phone is no longer on Samsung's list of phones that get security updates.
Matters most if: You plan to keep the phone for years, or you're buying one used.
Android upgrades promised
4 Android upgrades›Not stated by Samsung
What does this mean?
How many new versions of Android (with the matching One UI) Samsung promised this phone would get after the one it came with.
Samsung promises a number of versions rather than a date. Each upgrade brings new features; security updates are a separate promise, in the row above.
Matters most if: You want the newest Android features for years to come.
Android at launch
Android 13›Android 17
What does this mean?
The version of Android, Google's phone software, that was installed when the phone first came out. Samsung adds its own design and features on top, called One UI (TouchWiz on older phones).
A Galaxy moves to newer Android versions through updates, so this shows where it started, not what it runs today.
Galaxy AI
Yes (same on both)
What does this mean?
Galaxy AI is Samsung's name for its set of AI features, such as live translation of phone calls, writing help and photo editing that fills in parts of a picture.
Samsung lists which phones get Galaxy AI, at launch or through a One UI update. Some features work on the phone itself and others use the internet; Samsung lists which is which, and availability varies by language and country.
Matters most if: You want AI features such as call translation or photo editing built into the phone.

eBay may ask you to sign in to see sold prices.
Links open in a new tab. Prices are set by each seller and change daily.
Starting price
$799.99›$2,099.99+$1,300
What does this mean?
What Samsung charged in the US when the phone launched, for the version with the least storage, before sales tax. Phones from before about 2014 were often priced with a two-year carrier contract.
This is not what it costs today: check the used and refurbished links for current prices. If Samsung has not confirmed a price, the site shows "Price not confirmed by Samsung".
Same storage
256 GB: $859.99›$2,099.99+$1,240
What does this mean?
The launch price of the smallest storage option both models were sold with.
Starting prices can be for different amounts of storage. This row compares the same storage on both, so you can see what the newer model costs for what you have now. It is shown as a difference, not a gain or a loss.
Battery1 gain · 1 unconfirmed
Battery capacity
3900 mAh›5000 mAh+1100 mAh
What does this mean?
How much charge the battery holds, measured in mAh (milliamp-hours). Samsung lists a typical figure; we show the one Samsung gives.
A bigger number stores more energy, but how long a charge lasts also depends on the screen, the chip and which features you use.
Battery life (Samsung's figure)
Up to 22 hours of video playback›Not stated by Samsung
What does this mean?
Samsung's own figure for how long a full charge lasts in one of its tests, usually hours of video playback (talk time on older phones).
It is a lab test of one activity, so real use with a mix of apps is usually shorter. Compare it only with another Samsung figure for the same test.
Matters most if: You are often away from a charger all day.
Camera2 gains · 1 loss · 1 change · 1 not applicable
Main camera
50 MP›200 MP
What does this mean?
The resolution of the main camera's sensor in megapixels (MP), meaning millions of light-catching dots.
High-megapixel cameras usually combine neighboring dots into a smaller photo by default; you can switch to full resolution for large prints or cropping.
Matters most if: You want full-size photos for large prints or for cropping later.
Ultra wide camera
12 MP›50 MP
What does this mean?
The resolution in megapixels (MP) of the ultra wide camera: the lens that fits the most into the frame.
Use it for group photos, rooms and landscapes when you can't step back.
Matters most if: You shoot group photos, small rooms or landscapes.
Front camera
12 MP›10 MP
What does this mean?
The resolution in megapixels (MP) of the selfie camera on the front.
A higher number keeps more detail in selfies and video calls, but light and processing matter as much.
Inner screen camera
Not applicable›10 MP
What does this mean?
The camera in the inner (main) screen of a foldable, for video calls and selfies with the phone open.
"Under the screen" means the camera sits beneath the display, so the screen has no hole for it.
Video (best)
8K 30 fps›8K
Samsung gives no frame rate for the Galaxy Z Fold8 Ultra, so this may not be a real difference.
What does this mean?
The highest video quality the rear camera records. 4K and 8K describe the picture size (8K is larger), and fps (frames per second) is how many still images make up each second.
Higher settings make bigger files, so long 8K or 4K 60 fps clips fill storage quickly.
Matters most if: You film a lot.
Rear cameras
3 (same on both)
What does this mean?
How many cameras are on the back. Each one is a separate lens for a different view: wide (the main camera), ultra wide and telephoto (zoom), depending on the model.
More cameras let you switch between a wide scene and a zoomed-in view using real lenses instead of cutting out part of the picture.
Telephoto camera
10 MP (same on both)
What does this mean?
The resolution in megapixels (MP) of the telephoto camera: a separate zoom lens that sees far-away things as if you were closer. "None" means the phone has no telephoto camera. Some Ultra models have two.
At the telephoto's own zoom level, the photo comes from a real lens instead of a cropped, enlarged image.
Matters most if: You photograph kids' sports, concerts, pets or wildlife from a distance.
Optical zoom
3x optical zoom (same on both)
What does this mean?
How far the telephoto lens zooms on its own compared with the main camera (1x), for example '3x optical zoom'. Where Samsung lists two telephoto lenses, the comparison uses the longer one.
At this level the lens does the zooming, so no part of the image is cut away. 'Optical quality zoom' figures some models list come from cropping a high-resolution camera, not from a lens.
Matters most if: You compare zoom between phones: compare this row, not the 'up to' figures.
Digital zoom (most)
Up to 30x (same on both)
What does this mean?
The farthest the camera can zoom, with software doing the work beyond what the lenses reach. Samsung calls it Space Zoom on many models.
Past the lens's own zoom, the camera enlarges part of the picture and relies on processing to keep it sharp, so the highest levels lose detail.
Matters most if: You zoom far and need the photo to show fine details.
Screen3 changes · 1 unconfirmed · 4 not applicable
Screen size
6.1 in›8 in+1.9 in
What does this mean?
The screen size, measured corner to corner (diagonally) in inches. 1 inch is 25.4 mm.
Samsung measures the screen as a full rectangle, so with rounded corners the visible area is a little smaller.
Cover screen
Not applicable›6.5 in
What does this mean?
The size of the outer screen you use while the phone is folded, measured corner to corner in inches. Samsung calls it the cover screen (FlexWindow on the Flip phones).
On a Fold it is a full phone screen; on a Flip it is a smaller window for notifications, widgets and some apps. Samsung measures its screens as full rectangles, so with the rounded corners the visible area is a little smaller.
Cover screen type
Not applicable›Dynamic AMOLED 2X
What does this mean?
Samsung's name for the cover screen's panel, such as Dynamic AMOLED 2X or Super AMOLED.
The cover screen can use a different panel from the main screen, so this row can differ from Screen type.
Cover screen refresh rate
Not applicable›1-120Hz
What does this mean?
How many times per second the cover screen can redraw its picture, in Hz.
A range such as 1-120Hz means the screen slows down for still pictures to save battery; "60Hz or 120Hz" means it switches between two speeds.
Cover screen resolution
Not applicable›2520 x 1080
What does this mean?
How many pixels the cover screen has, across and down.
More pixels on a screen of the same size make text and photos look sharper.
Adaptive refresh rate
48-120Hz›1-120Hz
What does this mean?
The range of refresh rates the screen moves between on its own, in Samsung's words, such as '1~120Hz'. A screen that can slow to 1 Hz saves battery on still images.
The screen speeds up for scrolling and games and slows down for reading, to balance smoothness and battery life.
Matters most if: You care about battery life as well as smooth scrolling.
Peak brightness
1750 nits›Not stated by Samsung
As Samsung states it ("Peak"); Samsung does not say how it measures it, so compare it only with other Galaxy phones.
What does this mean?
The brightest the screen can get, in nits (a unit of screen brightness; higher is brighter), as Samsung measures it.
A high peak brightness makes the screen easier to see in direct sunlight. Makers measure peak brightness in different ways, so compare it only between phones from the same maker.
Matters most if: You use your phone outdoors a lot, such as for maps or photos in sunlight.
Resolution
2340 x 1080 (FHD+)›2504 x 2256
What does this mean?
How many dots (pixels) make up the screen, written as height x width, with a name such as Full HD+ or Quad HD+.
On screens of the same size, more pixels show text and photos in finer detail.
Screen type
Dynamic AMOLED 2X (same on both)
What does this mean?
The type of screen, in Samsung's own words, such as Super AMOLED or Dynamic AMOLED 2X. AMOLED screens light each dot on its own, so black areas are truly black.
The name alone does not tell you how bright or sharp a screen is, so compare the brightness, resolution and refresh rate rows.
Refresh rate (most)
120 Hz (same on both)
What does this mean?
How many times per second the screen redraws the picture, in hertz (Hz). 120 Hz means up to 120 times a second.
A higher rate makes scrolling and switching apps look smoother, and uses more battery.
Matters most if: You scroll social feeds, read long pages or play fast games.
Design & buttons3 changes · 1 unconfirmed · 4 not applicable
Unlock
Ultrasonic Fingerprint (in the screen), Face Recognition›Not stated by Samsung
What does this mean?
Ways to unlock the phone with your body instead of typing a PIN: a fingerprint sensor (in the screen, the side key, the home key or on the back), face recognition, or on some older models an iris scanner.
An ultrasonic sensor in the screen reads your finger with sound waves; others use light. Where the sensor sits changes how you unlock the phone with one hand.
Weight
168 g›215 g+47 g
What does this mean?
How much the phone weighs in grams (g); about 28 g is 1 ounce.
You feel the weight most when you hold the phone up for a long time, such as reading or filming.
Size (mm)
146.3 x 70.9 x 7.6›Not applicable
What does this mean?
The phone's size in millimeters (mm): height x width x depth (thickness). 25.4 mm is 1 inch.
Height and width tell you whether it fits your pocket and hand; depth is how thick it is.
Size folded (mm)
Not applicable›72.8 x 158.4 x 8.9
What does this mean?
The size of the phone when it is closed, in millimeters, as Samsung lists it.
This is the size in your pocket or bag. The last figure is the thickness.
Size unfolded (mm)
Not applicable›143.2 x 158.4 x 4.1
What does this mean?
The size of the phone when it is opened flat, in millimeters, as Samsung lists it.
The last figure is the thickness of the open phone, which is much less than when it is folded.
Flex Mode
Not applicable›Yes
What does this mean?
Samsung's name for using the phone half-folded, so it stands on its own, with some apps split between the top and bottom halves.
Useful for video calls, photos with the phone set down and watching videos hands-free.
Materials
Armor Aluminum frame; Corning Gorilla Glass Victus 2 on front and back›Flex Titanium (display structure)
What does this mean?
What the outside of the phone is made of: the cover glass over the screen and back, and the frame around the edge, as Samsung lists them.
Glass names such as Corning Gorilla Glass Victus or Gorilla Armor are tougher generations of glass; a titanium or aluminum frame changes the weight and feel more than the strength in daily use.
Water and dust resistance
IP68›IP48
What does this mean?
An IP rating has two digits: the first is for dust and other solids, the second for water. A 4 means protected against solid objects larger than 1 mm, but not against dust; a 6 means dust-tight. An 8 means Samsung tests the phone in 1.5 meters of fresh water for 30 minutes.
IP48 and IP68 are not the same: a foldable rated IP48 is not protected against dust and sand the way an IP68 phone is. Samsung advises against taking its foldables to the beach or the pool.
Matters most if: You use your phone outdoors, at the beach or in dusty places.
Headphone jack
No (same on both)
What does this mean?
Whether the phone has a 3.5 mm socket for wired headphones (the standard round headphone plug).
Without the jack, wired headphones need a USB-C plug or an adapter, or you use Bluetooth earbuds.
Charging & connections1 gain · 4 changes · 3 unconfirmed
USB port
USB-C, USB 3.2›USB-C (USB version not stated by Samsung)
What does this mean?
The kind of USB port Samsung lists: Micro USB on older phones, USB-C on newer ones, with a USB version such as USB 2.0 or USB 3.2. It concerns moving data over a cable, such as copying files to a computer.
A higher USB version can copy files faster with a cable that supports it. Charging speed is listed separately.
Wired charging
Up to 25W›Up to 45W
What does this mean?
How fast the phone charges with a cable, in Samsung's words, such as Super Fast Charging (25W or 45W). W (watts) is how much power the charger can deliver.
The top speed needs a charger and cable that support it; recent Galaxy phones come with a cable but no charger.
Matters most if: You often need a quick top-up before heading out.
Wireless charging
Fast Wireless Charging 2.0›Up to 20W
What does this mean?
Whether and how fast the phone charges on a wireless charging pad, in Samsung's words, such as Fast Wireless Charging 2.0.
The fastest speed usually needs a matching Samsung charger. Wireless charging is slower than a cable but saves plugging in.
Wi-Fi
Wi-Fi 6E›Wi-Fi 7
What does this mean?
The Wi-Fi generation, such as Wi-Fi 5, Wi-Fi 6E or Wi-Fi 7. 6E and 7 can also use the 6 GHz band, which is less crowded. Older phones list only the 802.11 letters (n is Wi-Fi 4, ac is Wi-Fi 5, ax is Wi-Fi 6).
A newer generation helps only with a router that supports it, and the 6 GHz band is not allowed in every country.
Matters most if: You have, or plan to buy, a Wi-Fi 6E or Wi-Fi 7 router.
Bluetooth
v5.3›v6.0
What does this mean?
Bluetooth connects wireless accessories, such as earbuds and watches, to the phone. The number, such as v5.3, is the Bluetooth version.
Newer versions add features such as LE Audio, but your earbuds or watch need to support them too.
Ultra Wideband
No›Not stated by Samsung
What does this mean?
Ultra-Wideband (UWB) is a radio chip that measures how far away another UWB device is and in which direction. It only works with another device that also has UWB.
With a tracker tag that has UWB, such as a Galaxy SmartTag+, the phone can show distance and direction to find keys or a bag.
Matters most if: You use tracker tags to find keys or bags.
mmWave 5G
Yes›Not stated by Samsung
What does this mean?
mmWave ("millimeter wave") is a high-band type of 5G. The more common type, Sub-6, uses frequencies below 6 GHz. Usually only the US versions of Galaxy phones can use mmWave.
You need a carrier with mmWave 5G where you use the phone; the carrier's network decides which type the phone uses.
Matters most if: Your carrier offers mmWave 5G where you live or work.
SIM
SIM card and eSIM›Dual-SIM: SIM 1 + eSIM / Dual eSIM (Nano-SIM (4FF), Embedded-SIM)
Worded by this site from Samsung's eSIM and SIM card slot details; Samsung's own SIM wording for this version was not checked.
What does this mean?
Which SIM the phone takes: a SIM card from your carrier in a tray (nano SIM), an eSIM (a digital SIM built into the phone), or both. Samsung lists the combinations, such as "SIM 1 + eSIM".
Whether you can use eSIM depends on your carrier and country. Some versions of a model take two SIM cards, others one SIM card and an eSIM.
Matters most if: You travel abroad or want two phone lines on one phone.
Qi2 magnetic charging
Not stated by Samsung (for both)
What does this mean?
Qi2 is a wireless charging standard with magnets that hold the charger in the right spot.
Samsung says which Galaxy phones work with Qi2 chargers, and whether they need a case with magnets for the charger to snap on.
Matters most if: You want a charger or stand that snaps onto the phone.
Wireless PowerShare
Yes (same on both)
What does this mean?
Wireless PowerShare lets the phone wirelessly charge another device, such as Galaxy Buds or a Galaxy Watch, placed on its back.
It works with devices that charge wirelessly, and it uses the phone's own battery.
Matters most if: You carry wireless earbuds or a watch and want to top them up away from a charger.
FeliCa
Not stated by Samsung (for both)
What does this mean?
FeliCa is the contactless chip behind Osaifu-Keitai, the tap-to-pay service used in Japan for transit cards such as Suica and e-money such as WAON.
Samsung Japan lists it for the Galaxy versions sold in Japan; versions sold elsewhere do not have it.
Matters most if: You live in Japan, or want to use Suica or other Osaifu-Keitai services.
Chip & storage3 changes · 1 unconfirmed
Chip
Snapdragon 8 Gen 2 for Galaxy›Snapdragon 8 Elite Gen 5 for Galaxy
What does this mean?
The main processor: the part that runs apps, camera processing and on-device AI. Samsung uses its own Exynos chips in some countries and Qualcomm Snapdragon chips in others, sometimes for the same model.
Where the chip depends on the country, the page shows a switch for the versions Samsung lists. A newer phone can have an older chip, so compare the chip names rather than the year.
Matters most if: You are buying a model that was sold with two different chips.
Security chip
Knox Vault›Not stated by Samsung
What does this mean?
A separate secure processor that keeps passwords, PINs and other sensitive data apart from the rest of the phone. Samsung calls it Knox Vault.
Phones where Samsung names no security processor still have Samsung Knox security in their software; this row only shows a separate chip Samsung names.
RAM
8 GB›12 GB or 16 GB
What does this mean?
RAM is the phone's short-term working memory for the apps running right now, measured in GB (gigabytes).
More RAM lets more apps stay open in the background. RAM is separate from storage, which holds your apps, photos and files. On some Galaxy phones it depends on the storage size or the country.
Storage options
128 GB, 256 GB›256 GB, 512 GB, 1 TB
What does this mean?
How much space the phone has for apps, photos, videos and files, in GB (gigabytes) or TB (terabytes; 1 TB is 1,000 GB).
Each storage size is sold at its own price, and not every size is sold in every country. You get less usable space than the number shown, because some of it holds the phone's own software.

Main camera
50 MP›200 MP
What does this mean?
The resolution of the main camera's sensor in megapixels (MP), meaning millions of light-catching dots.
High-megapixel cameras usually combine neighboring dots into a smaller photo by default; you can switch to full resolution for large prints or cropping.
Matters most if: You want full-size photos for large prints or for cropping later.

The camera in the inner (main) screen of a foldable, for video calls and selfies with the phone open.
"Under the screen" means the camera sits beneath the display, so the screen has no hole for it.
Video (best)
8K 30 fps›8K
Samsung gives no frame rate for the Galaxy Z Fold8 Ultra, so this may not be a real difference.
What does this mean?
The highest video quality the rear camera records. 4K and 8K describe the picture size (8K is larger), and fps (frames per second) is how many still images make up each second.
Higher settings make bigger files, so long 8K or 4K 60 fps clips fill storage quickly.

3 (same on both)
What does this mean?
How many cameras are on the back. Each one is a separate lens for a different view: wide (the main camera), ultra wide and telephoto (zoom), depending on the model.
More cameras let you switch between a wide scene and a zoomed-in view using real lenses instead of cutting out part of the picture.
Telephoto camera
10 MP (same on both)
What does this mean?
The resolution in megapixels (MP) of the telephoto camera: a separate zoom lens that sees far-away things as if you were closer. "None" means the phone has no telephoto camera. Some Ultra models have two.
At the telephoto's own zoom level, the photo comes from a real lens instead of a cropped, enlarged image.
Matters most if: You photograph kids' sports, concerts, pets or wildlife from a distance.

Screen size
6.1 in›8 in+1.9 in
What does this mean?
The screen size, measured corner to corner (diagonally) in inches. 1 inch is 25.4 mm.
Samsung measures the screen as a full rectangle, so with rounded corners the visible area is a little smaller.
Cover screen
Not applicable›6.5 in
What does this mean?
The size of the outer screen you use while the phone is folded, measured corner to corner in inches. Samsung calls it the cover screen (FlexWindow on the Flip phones).
On a Fold it is a full phone screen; on a Flip it is a smaller window for notifications, widgets and some apps. Samsung measures its screens as full rectangles, so with the rounded corners the visible area is a little smaller.
Cover screen type
Not applicable›Dynamic AMOLED 2X
What does this mean?
Samsung's name for the cover screen's panel, such as Dynamic AMOLED 2X or Super AMOLED.
The cover screen can use a different panel from the main screen, so this row can differ from Screen type.
Cover screen refresh rate
Not applicable›1-120Hz
What does this mean?
How many times per second the cover screen can redraw its picture, in Hz.
A range such as 1-120Hz means the screen slows down for still pictures to save battery; "60Hz or 120Hz" means it switches between two speeds.
Cover screen resolution
Not applicable›2520 x 1080
What does this mean?
How many pixels the cover screen has, across and down.
More pixels on a screen of the same size make text and photos look sharper.
Adaptive refresh rate
48-120Hz›1-120Hz
What does this mean?
The range of refresh rates the screen moves between on its own, in Samsung's words, such as '1~120Hz'. A screen that can slow to 1 Hz saves battery on still images.
The screen speeds up for scrolling and games and slows down for reading, to balance smoothness and battery life.
Matters most if: You care about battery life as well as smooth scrolling.
Peak brightness
1750 nits›Not stated by Samsung
As Samsung states it ("Peak"); Samsung does not say how it measures it, so compare it only with other Galaxy phones.
What does this mean?
The brightest the screen can get, in nits (a unit of screen brightness; higher is brighter), as Samsung measures it.
A high peak brightness makes the screen easier to see in direct sunlight. Makers measure peak brightness in different ways, so compare it only between phones from the same maker.
Matters most if: You use your phone outdoors a lot, such as for maps or photos in sunlight.
Resolution
2340 x 1080 (FHD+)›2504 x 2256
What does this mean?
How many dots (pixels) make up the screen, written as height x width, with a name such as Full HD+ or Quad HD+.
On screens of the same size, more pixels show text and photos in finer detail.
Screen type
Dynamic AMOLED 2X (same on both)
What does this mean?
The type of screen, in Samsung's own words, such as Super AMOLED or Dynamic AMOLED 2X. AMOLED screens light each dot on its own, so black areas are truly black.
The name alone does not tell you how bright or sharp a screen is, so compare the brightness, resolution and refresh rate rows.
Refresh rate (most)
120 Hz (same on both)
What does this mean?
How many times per second the screen redraws the picture, in hertz (Hz). 120 Hz means up to 120 times a second.
A higher rate makes scrolling and switching apps look smoother, and uses more battery.
Matters most if: You scroll social feeds, read long pages or play fast games.
Design & buttons3 changes · 1 unconfirmed · 4 not applicable
Unlock
Ultrasonic Fingerprint (in the screen), Face Recognition›Not stated by Samsung
What does this mean?
Ways to unlock the phone with your body instead of typing a PIN: a fingerprint sensor (in the screen, the side key, the home key or on the back), face recognition, or on some older models an iris scanner.
An ultrasonic sensor in the screen reads your finger with sound waves; others use light. Where the sensor sits changes how you unlock the phone with one hand.
Weight
168 g›215 g+47 g
What does this mean?
How much the phone weighs in grams (g); about 28 g is 1 ounce.
You feel the weight most when you hold the phone up for a long time, such as reading or filming.
Size (mm)
146.3 x 70.9 x 7.6›Not applicable
What does this mean?
The phone's size in millimeters (mm): height x width x depth (thickness). 25.4 mm is 1 inch.
Height and width tell you whether it fits your pocket and hand; depth is how thick it is.
Size folded (mm)
Not applicable›72.8 x 158.4 x 8.9
What does this mean?
The size of the phone when it is closed, in millimeters, as Samsung lists it.
This is the size in your pocket or bag. The last figure is the thickness.
Size unfolded (mm)
Not applicable›143.2 x 158.4 x 4.1
What does this mean?
The size of the phone when it is opened flat, in millimeters, as Samsung lists it.
The last figure is the thickness of the open phone, which is much less than when it is folded.
Flex Mode
Not applicable›Yes
What does this mean?
Samsung's name for using the phone half-folded, so it stands on its own, with some apps split between the top and bottom halves.
Useful for video calls, photos with the phone set down and watching videos hands-free.
Materials
Armor Aluminum frame; Corning Gorilla Glass Victus 2 on front and back›Flex Titanium (display structure)
What does this mean?
What the outside of the phone is made of: the cover glass over the screen and back, and the frame around the edge, as Samsung lists them.
Glass names such as Corning Gorilla Glass Victus or Gorilla Armor are tougher generations of glass; a titanium or aluminum frame changes the weight and feel more than the strength in daily use.
Water and dust resistance
IP68›IP48
What does this mean?
An IP rating has two digits: the first is for dust and other solids, the second for water. A 4 means protected against solid objects larger than 1 mm, but not against dust; a 6 means dust-tight. An 8 means Samsung tests the phone in 1.5 meters of fresh water for 30 minutes.
IP48 and IP68 are not the same: a foldable rated IP48 is not protected against dust and sand the way an IP68 phone is. Samsung advises against taking its foldables to the beach or the pool.
Matters most if: You use your phone outdoors, at the beach or in dusty places.
Headphone jack
No (same on both)
What does this mean?
Whether the phone has a 3.5 mm socket for wired headphones (the standard round headphone plug).
Without the jack, wired headphones need a USB-C plug or an adapter, or you use Bluetooth earbuds.
Charging & connections1 gain · 4 changes · 3 unconfirmed
USB port
USB-C, USB 3.2›USB-C (USB version not stated by Samsung)
What does this mean?
The kind of USB port Samsung lists: Micro USB on older phones, USB-C on newer ones, with a USB version such as USB 2.0 or USB 3.2. It concerns moving data over a cable, such as copying files to a computer.
A higher USB version can copy files faster with a cable that supports it. Charging speed is listed separately.
Wired charging
Up to 25W›Up to 45W
What does this mean?
How fast the phone charges with a cable, in Samsung's words, such as Super Fast Charging (25W or 45W). W (watts) is how much power the charger can deliver.
The top speed needs a charger and cable that support it; recent Galaxy phones come with a cable but no charger.
Matters most if: You often need a quick top-up before heading out.
Wireless charging
Fast Wireless Charging 2.0›Up to 20W
What does this mean?
Whether and how fast the phone charges on a wireless charging pad, in Samsung's words, such as Fast Wireless Charging 2.0.
The fastest speed usually needs a matching Samsung charger. Wireless charging is slower than a cable but saves plugging in.
Wi-Fi
Wi-Fi 6E›Wi-Fi 7
What does this mean?
The Wi-Fi generation, such as Wi-Fi 5, Wi-Fi 6E or Wi-Fi 7. 6E and 7 can also use the 6 GHz band, which is less crowded. Older phones list only the 802.11 letters (n is Wi-Fi 4, ac is Wi-Fi 5, ax is Wi-Fi 6).
A newer generation helps only with a router that supports it, and the 6 GHz band is not allowed in every country.
Matters most if: You have, or plan to buy, a Wi-Fi 6E or Wi-Fi 7 router.
Bluetooth
v5.3›v6.0
What does this mean?
Bluetooth connects wireless accessories, such as earbuds and watches, to the phone. The number, such as v5.3, is the Bluetooth version.
Newer versions add features such as LE Audio, but your earbuds or watch need to support them too.
Ultra Wideband
No›Not stated by Samsung
What does this mean?
Ultra-Wideband (UWB) is a radio chip that measures how far away another UWB device is and in which direction. It only works with another device that also has UWB.
With a tracker tag that has UWB, such as a Galaxy SmartTag+, the phone can show distance and direction to find keys or a bag.
Matters most if: You use tracker tags to find keys or bags.
mmWave 5G
No›Not stated by Samsung
What does this mean?
mmWave ("millimeter wave") is a high-band type of 5G. The more common type, Sub-6, uses frequencies below 6 GHz. Usually only the US versions of Galaxy phones can use mmWave.
You need a carrier with mmWave 5G where you use the phone; the carrier's network decides which type the phone uses.
Matters most if: Your carrier offers mmWave 5G where you live or work.
SIM
Dual-SIM: SIM 1 + SIM 2 or Embedded SIM (Nano-SIM (4FF), Embedded-SIM)›Dual-SIM: SIM 1 + eSIM / Dual eSIM (Nano-SIM (4FF), Embedded-SIM)
What does this mean?
Which SIM the phone takes: a SIM card from your carrier in a tray (nano SIM), an eSIM (a digital SIM built into the phone), or both. Samsung lists the combinations, such as "SIM 1 + eSIM".
Whether you can use eSIM depends on your carrier and country. Some versions of a model take two SIM cards, others one SIM card and an eSIM.
Matters most if: You travel abroad or want two phone lines on one phone.
Qi2 magnetic charging
Not stated by Samsung (for both)
What does this mean?
Qi2 is a wireless charging standard with magnets that hold the charger in the right spot.
Samsung says which Galaxy phones work with Qi2 chargers, and whether they need a case with magnets for the charger to snap on.
Matters most if: You want a charger or stand that snaps onto the phone.
Wireless PowerShare
Yes (same on both)
What does this mean?
Wireless PowerShare lets the phone wirelessly charge another device, such as Galaxy Buds or a Galaxy Watch, placed on its back.
It works with devices that charge wirelessly, and it uses the phone's own battery.
Matters most if: You carry wireless earbuds or a watch and want to top them up away from a charger.
FeliCa
Not stated by Samsung (for both)
What does this mean?
FeliCa is the contactless chip behind Osaifu-Keitai, the tap-to-pay service used in Japan for transit cards such as Suica and e-money such as WAON.
Samsung Japan lists it for the Galaxy versions sold in Japan; versions sold elsewhere do not have it.
Matters most if: You live in Japan, or want to use Suica or other Osaifu-Keitai services.
Chip & storage3 changes · 1 unconfirmed
Chip
Snapdragon 8 Gen 2 for Galaxy›Snapdragon 8 Elite Gen 5 for Galaxy
What does this mean?
The main processor: the part that runs apps, camera processing and on-device AI. Samsung uses its own Exynos chips in some countries and Qualcomm Snapdragon chips in others, sometimes for the same model.
Where the chip depends on the country, the page shows a switch for the versions Samsung lists. A newer phone can have an older chip, so compare the chip names rather than the year.
Matters most if: You are buying a model that was sold with two different chips.
Security chip
Knox Vault›Not stated by Samsung
What does this mean?
A separate secure processor that keeps passwords, PINs and other sensitive data apart from the rest of the phone. Samsung calls it Knox Vault.
Phones where Samsung names no security processor still have Samsung Knox security in their software; this row only shows a separate chip Samsung names.
RAM
8 GB›12 GB or 16 GB
What does this mean?
RAM is the phone's short-term working memory for the apps running right now, measured in GB (gigabytes).
More RAM lets more apps stay open in the background. RAM is separate from storage, which holds your apps, photos and files. On some Galaxy phones it depends on the storage size or the country.
Storage options
128 GB, 256 GB, 512 GB›256 GB, 512 GB, 1 TB
What does this mean?
How much space the phone has for apps, photos, videos and files, in GB (gigabytes) or TB (terabytes; 1 TB is 1,000 GB).
Each storage size is sold at its own price, and not every size is sold in every country. You get less usable space than the number shown, because some of it holds the phone's own software.
