I transfered my SIM without any issues to the Galaxy S23, and I've been very stressed and watching more You Tube than usual and the battery is holding up amazingly well. One charge even with the video watching lasts more than a day.

(Note: The condition of this phone was listed as "excellent" in my original order, not "very good." My review is based on the original description). This is my second BackMarket purchase (previous one for an S22 for a relative). That experience was positive and was a factor in making another phone purchase, this time for myself. As previously, the search and purchase process was very easy. The phone was delivered very quickly and just as-described: in excellent condition with no noticeable scratches or cracks. With a little assistance from AT&T, I was able to swap my existing SIM card and then used Samsung Smart Switch to migrate all my existing phone data to the new one in about an hour. I've been using the S23 for about a week and no issues at all. I'm very pleased with the whole experience at BackMarket and would trust them for any future support and purchases.

The Galaxy S23 is Samsung’s 2023 flagship, and while it’s now a generation behind the latest, it still packs plenty of flagship-worthy features. With its handy size, advanced camera system, and fast processor, this phone keeps up with the pace of modern life—no wild claims, just reliable performance for people who want a stylish, powerful Android with a proven track record.

Key features:

Release Date: February 2023
Display: 6.1-inch Dynamic AMOLED 2X, FHD+ (2340 x 1080 px), 120Hz refresh rate
Processor: Qualcomm Snapdragon 8 Gen 2 for Galaxy
Camera: Triple rear cameras: 50MP (wide) + 12MP (ultra-wide) + 10MP (telephoto), 12MP front camera
Operating System: Ships with Android 13 (One UI 5.1)
Build: Gorilla Glass Victus 2 (front & back), Armor Aluminum frame
Connectivity: 5G compatible, Wi-Fi 6E support

Who is this for?

The Galaxy S23 is a solid pick for professionals and students who want premium features—like a fast display, excellent cameras, and dependable build quality—without chasing the absolutely latest tech. It’s smaller and easier to use one-handed than larger models like the S23 Ultra, while offering a better balance of usability and performance than older Samsung flagships. If you’re after a practical, durable, and modern Android, this one’s for you.

Pros & Cons: Pros Cons Compact flagship build—easy to use with one hand. No expandable storage—microSD slot is nowhere to be found (again). Fast, smooth display with 120Hz refresh rate. Camera zoom isn’t as advanced as the Ultra models. Gorilla Glass Victus 2 for improved durability. Incremental updates over the S22—expect evolution, not revolution.
Why refurbished?

Choosing a refurbished Galaxy S23 supports tech that’s built to last and the planet, too—less waste, same modern features. Every pre-owned device on Back Market goes through rigorous testing and quality checks for peace of mind. Learn more about our quality standards.
