The Samsung Galaxy S24 Ultra launched in 2024 as Samsung's flagship phablet, built for anyone who wanted the largest screen, the best camera array, and a built-in S Pen without stepping outside the Galaxy S line. Sold under model numbers SM-S928, SM-S928U, and SM-S928U1 depending on carrier and retailer, it replaced the Note line's stylus ambitions with a titanium-framed body and a 200MP main camera. Two years on, it still commands strong resale interest because Samsung's flagships hold software support far longer than mid-range phones, and the hardware itself, Snapdragon 8 Gen 3, 12GB of RAM, a 5000mAh battery, remains competitive. Pick your carrier, storage tier, and condition in the picker above for a live cash offer. If you want the mechanics first, see how the process works, or head straight to the page to sell your smartphone.

Confirm you have the Galaxy S24 Ultra

Open Settings → About phone → Model number. You will see one of the numbers below, along with the storage figure under Storage and the carrier under Status information. If the phone is locked to a network, that carrier's name usually appears in the status bar or under About phone as well.

SM-S928U

  • Standard US retail and carrier model
  • Sold through AT&T, T-Mobile, Verizon, and carrier stores
  • Can be carrier-locked or factory unlocked depending on point of sale

SM-S928U1

  • Unlocked model sold directly by Samsung.com and major unlocked retailers
  • Accepts SIMs from any US carrier out of the box
  • Same hardware as SM-S928U, different firmware channel

SM-S928

  • Global unlocked variant, occasionally imported or resold in the US
  • Same Snapdragon 8 Gen 3 platform used worldwide for this model
  • Verify US LTE/5G band support before assuming full carrier compatibility

Prefer a visual check? Look for the S Pen silo along the bottom edge, a flat titanium frame with no camera bump curve into the sides, and a rear camera cluster of four separate lens rings rather than a single raised module. If any of those are missing, you likely have a different Galaxy S24 model.

Core hardware

Processor

  • Qualcomm Snapdragon 8 Gen 3 for Galaxy
  • Used across every US carrier and storage configuration

Memory

  • 12GB RAM on all storage tiers
  • Soldered, not user-upgradable

Storage

  • 256GB, 512GB, or 1TB, UFS 4.0
  • No microSD expansion
  • The 1TB configuration moves resale value the most, since it was the least common tier at launch

Cameras

  • 200MP wide main sensor
  • 50MP telephoto (5x optical)
  • 10MP telephoto (3x optical)
  • 12MP ultrawide, 12MP front-facing

Display & audio

Display — 6.8-inch Dynamic AMOLED 2X, QHD+ resolution, 1-120Hz adaptive refresh, flat panel with Corning Gorilla Armor, rated for high outdoor brightness.

Audio — Stereo speakers tuned with AKG, no headphone jack, Dolby Atmos support for both playback and recording.

Security — Ultrasonic in-display fingerprint sensor plus face recognition via the front camera.

Ports & connectivity

A single USB-C port handles charging and data. There is no headphone jack and no expandable storage slot, so the SIM tray is the only other physical opening on the frame.

Wired
  • USB-C 3.2 (data and charging)
  • Nano-SIM tray (dual SIM on some models, eSIM supported)
Wireless
  • 5G sub-6 and mmWave (carrier dependent)
  • Wi-Fi 6E
  • Bluetooth 5.3
  • NFC and Ultra Wideband (UWB)

Battery, build & more

Battery — 5000mAh, supports wired fast charging, wireless charging, and reverse wireless charging.

Dimensions & weight — approximately 162.3 x 79.0 x 8.6mm, about 232 grams, the heaviest phone in the Galaxy S24 lineup due to the S Pen silo and larger battery.

Finishes — Titanium Black, Gray, Violet, and Yellow were the standard retail colors, with Titanium Blue, Green, and Orange sold as online exclusives.

Software — Launched on One UI 6.1 over Android 14. Samsung committed to extended OS and security update support for this generation, which keeps resale demand steady well past the launch window.

Market positioning — This is Samsung's top-tier flagship for its release year, priced accordingly at launch and still tracking as a premium-tier trade-in today, especially at the higher storage capacities.

Frequently asked questions

01 How do I find the model number and exact configuration?
Go to Settings → About phone → Model number to see whether you have SM-S928, SM-S928U, or SM-S928U1. The same screen lists storage capacity under Storage, and the Status information menu shows which carrier, if any, the device is tied to. If Settings is not accessible because the phone is locked, the model number is also printed on the original box and on the SIM tray itself in most cases.
02 How do I tell it apart from the Galaxy S24+?
Check for the S Pen slot along the bottom edge and the model number. The S24 Ultra (SM-S928) has a built-in S Pen silo, a flat titanium frame, a 6.8-inch display, and four rear camera lenses including two telephoto sensors. The S24+ (SM-S926) has no S Pen, an aluminum frame, a slightly smaller 6.7-inch display, and only three rear cameras with a single telephoto lens. If the model number reads SM-S926, you have the Plus, not the Ultra.
03 Can I sell it with damage, a weak battery, or an account lock?
Yes, a cracked screen, a battery that no longer holds a charge, or a phone that won't power on can still be sold, just select the matching condition in the picker above so the offer reflects reality. The one requirement that cannot be skipped is removing your Samsung account and Google account, and turning off Find My Mobile, before shipping. A device still locked to a personal account cannot be resold or recycled properly and will be rejected.
04 What raises the trade-in value the most?
Storage capacity and carrier status matter most. A 1TB unit typically quotes higher than a 256GB one, and a factory-unlocked phone quotes higher than one still locked to a single carrier, since it can be resold to a wider market. Screen and frame condition come next, since the titanium edges and flat glass show wear clearly. A fully working battery that still holds a normal charge also helps, since batteries are one of the first things checked during testing.
05 How do I erase it and remove my accounts, and how do I get paid?
Back up anything you want to keep, then go to Settings → Accounts and remove your Samsung account and Google account. Next, open Settings → Security and privacy → Find My Mobile and turn it off. Finally, go to Settings → General management → Reset → Factory data reset to erase the device. Full erasure steps are also laid out at our data erasure protocols page. Once the reset is done, ship the phone using the free, insured label from your order. Payment goes out after testing, by PayPal, Venmo, Zelle, CashApp, or check, whichever you select at checkout.
