What Samsung Phone Do I Have? How to Identify Your Model

The marketing name on the box and the model number inside the phone are different things, and you sometimes need both.

Find it in Settings

1. Open Settings.
2. Scroll to the bottom and tap About phone.
3. Read Model name (e.g. Galaxy S24 Ultra) and Model number (e.g. SM-S928B).

Also on this screen: serial number, IMEI, and under Software information, your Android and One UI versions.

Other places to look

• *Dial `#06#`** — shows the IMEI immediately, on any phone, even at the lock screen on some models.
• The SIM tray — many Galaxy phones print the model number on the tray itself.
• The back of the phone — fine print near the bottom on some models.
• The retail box — a label with the model number, IMEI and serial number.
• Your Google account — go to myaccount.google.com › Security › Your devices to see every device signed in, by name.
• Samsung Members › My devices — lists registered devices with warranty status.

If the phone will not turn on

• Check the box, or the receipt.
• Look at the SIM tray print.
• Check your Google account device list at myaccount.google.com.
• Check your carrier account, which lists the device on your line.

Decoding the model number

Samsung model numbers follow a consistent pattern. SM-S928B breaks down as:

Common region suffixes

The suffix matters more than people expect. It determines which software updates you receive, which cellular bands are supported, and whether carrier bloatware is present. When buying an imported phone, the suffix tells you what you are actually getting.

Why you need the model number

• Cases and screen protectors. An S24 and an S24+ are different sizes. Buying by marketing name alone leads to a case that does not fit.
• Replacement parts. Screens and batteries are model-specific.
• Firmware. Flashing firmware for the wrong variant can brick a phone.
• Trade-in valuations ask for the exact model.
• Support. Samsung's help pages branch by model number.

Find your Android and One UI version

Settings › About phone › Software information.

You will see the Android version, the One UI version and the security patch level. Both matter: guides written for One UI 6 may not match One UI 7 exactly, and the patch date tells you whether the phone is still receiving security updates.

Is your phone still supported?

Check the security patch date under Software information. If it is more than several months old and Settings › Software update › Download and install reports no updates, the device has likely reached end of support.

Samsung's current policy for recent flagship and mid-range devices provides several years of OS upgrades plus security patches — among the longest in the Android industry. Older devices had shorter commitments.

An unsupported phone still works, but it stops receiving security fixes, which is a real consideration for anything holding banking apps. See how long Samsung phones last.

Identify the storage and RAM

Settings › About phone › Storage shows total capacity, and Battery and device care › Memory shows RAM.

Note that advertised capacity always exceeds usable space — the operating system occupies a meaningful portion. A "128 GB" phone typically offers around 105–110 GB usable, which is normal and not a fault.

Check whether it is genuine

If you bought second-hand and want to verify authenticity:

• *Dial `#06#`** and check the IMEI matches the box and the SIM tray.
• Check the IMEI on your carrier's or a national regulator's blacklist service to confirm it is not reported stolen.
• Settings › About phone should show a plausible Samsung model number in the SM- format.
• Dial *#0*# for Samsung's hardware test menu — one of several hidden diagnostic codes. Counterfeits rarely implement it.

In short

Settings › About phone gives you the model name and number. The number, in SM- format, identifies the exact regional variant — needed for cases, parts, firmware and support. Dial *#06# for the IMEI.
