The Samsung Galaxy S10+ launched in 2019 as the flagship of Samsung's tenth-anniversary Galaxy S lineup, sold under model numbers SM-G975 (global/unlocked) and SM-G975U (US carrier and unlocked variants). It was built for buyers who wanted the largest, most fully equipped S10 without stepping up to the 5G model: a bigger Dynamic AMOLED display, a dual front camera, and the option of 512GB or a full terabyte of storage. Even years past release, it holds value because of that headphone jack, expandable storage, and IP68 build that later flagships dropped one by one. Pick your storage tier and condition in the tool above for an instant cash offer that adjusts to what you actually have in hand. If you want the mechanics first, see how the process works, or head straight to sell your smartphone once you know your configuration.

Confirm you have the Galaxy S10+

Go to Settings → About phone. The model number sits under "Model number," and storage capacity is listed under Settings → Battery and device care → Storage. This is the fastest way to separate an SM-G975 unit from an SM-G975U, and to see whether you have 128GB, 512GB, or 1TB.

SM-G975

  • Global and international unlocked variant
  • Commonly paired with the Exynos 9820 processor
  • Sold outside the United States

SM-G975U

  • US carrier and US unlocked variant
  • Built around the Qualcomm Snapdragon 855
  • Model number printed on the SIM tray and in Settings

Prefer a visual check? Look at the front camera cutout: the S10+ has two lenses side by side in the top right corner, not one. It also carries a triple rear camera arranged horizontally, a curved-edge 6.4-inch display, and a 3.5mm headphone jack at the bottom edge next to the USB-C port.

Audio

Stereo speakers tuned by AKG with Dolby Atmos support, plus a 3.5mm headphone jack, one of the last Samsung flagships to keep it.

Security

Ultrasonic in-display fingerprint sensor, backed up by 2D face recognition for faster, lower-security unlocking.

Ports & connectivity

The S10+ keeps a wired headphone jack alongside modern wireless standards, which is part of why it still appeals to buyers replacing older phones.

Battery, build & more

Battery

4,100mAh with 15W wired fast charging, fast wireless charging, and Wireless PowerShare to charge other devices from the phone's own battery.

Finishes

Standard glass-back colors include Prism White, Prism Black, Prism Green, and Prism Blue. Ceramic White and Ceramic Black variants, offered on the higher storage tiers, use a heavier ceramic back panel.

Software

Shipped on Android 9 Pie with One UI and received updates through Android 12 (One UI 4.1) before reaching the end of its official support window.

Known issues

Early units had a well-documented flaw where certain third-party screen protectors could confuse the ultrasonic fingerprint sensor and allow unauthorized unlocking. Samsung addressed it with a software patch, so check that any protector on a unit you receive is a Samsung-approved one.

Market positioning

As a 2019 flagship with a headphone jack, expandable storage, and IP68 water resistance, it still sits above budget Android phones in resale demand, particularly in the 512GB and 1TB tiers.

Frequently asked questions

01 How do I find the model number and exact configuration?
Go to Settings → About phone and read the "Model number" field, which will show SM-G975 or SM-G975U along with a carrier or region suffix. For storage, check Settings → Battery and device care → Storage, or Settings → About phone → Device storage. RAM is not user-visible on stock Android but is fixed to your storage tier: 8GB on 128GB and 512GB models, 12GB on 1TB models. If the phone won't boot, the model number is also printed on the SIM tray.
02 How do I tell it apart from the Galaxy S10?
Look at the front camera cutout first. The standard Galaxy S10 has a single front lens, while the S10+ has two lenses side by side for its dual selfie camera. The S10+ also has a larger 6.4-inch display compared to the S10's 6.1-inch panel, and a bigger 4,100mAh battery versus the S10's 3,400mAh. If the cutout has two visible lenses, you have the Plus model.
03 Can I sell it with damage, a weak battery, or if it won't turn on?
Yes, a cracked screen, a battery that no longer holds a charge, or a phone that won't power on can still be sold; select the condition that matches and the quote adjusts. What you cannot skip is account removal: sign out of your Samsung account and Google account, and turn off Find My Mobile and Factory Reset Protection before shipping. A phone still locked to a Samsung or Google account cannot be resold or fully tested, and that affects what it's worth.
04 What raises the trade-in value the most?
Higher storage tiers matter most: a 1TB or 512GB unit is worth more than a 128GB one in the same condition. Beyond that, an unlocked, carrier-free phone is generally worth more than one still tied to a carrier account, and a screen and battery in good working order matter more than cosmetic scuffs on the frame. Having the original box and charging cable helps but is not required. Removing your Samsung and Google accounts before you send it in avoids delays that can hold up payment.
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 backup → Manage accounts and remove your Samsung account and Google account individually. Next, go to Settings → Biometrics and security → Find My Mobile and turn it off, since an active Find My Mobile session can lock the device for its next owner. Then go to Settings → General management → Reset → Factory data reset and confirm. Once the device is wiped and the accounts are clear, ship it to us; shipping is free and insured. Payment goes out after inspection, by PayPal, Venmo, Zelle, CashApp, or check. Full erasure steps for every device type are covered in our data erasure protocols.
