The A51 was described as a 'Locked At&t device". it turned out to be locked to some other network. I since have seen quite a few negative reviews for Koala Stash external to BackMarket . I had purchased 2 phones several years and another one with this A51. I am very happy with these other purchases.

This phone saved my sanity. I was juggling my UK phone & a crappy US phone This is proof that using a Straight Talk/WalMart phone company shouldn't meet you have to settle for a bad phone or pay astronomical prices for a new one. Well done Back Market!

The phone works great just didn't expect a crack to be in the middle of the screen. It said good condition was minor scratches and some wear from use but a crack is a little more than minor because the more you use the phone the bigger that crack gets.

It's a nice phone, I am not so found of it yet, it is totally different than my last one. I am hoping it grows on me. I have been a motorola fan for years so this is taking some getting use to. The ease of ordering was great, phone is very nice.

The Samsung Galaxy A51 remains a popular mid-range smartphone since its release in late 2019. It offers a balanced combination of a large AMOLED display and versatile camera setup, making it suitable for everyday use despite being a few generations old.

Key features:

Release Date: December 2019
Display: 6.5-inch Super AMOLED, 1080 x 2400 pixels
Processor: Exynos 9611
Camera: Quad rear cameras – 48MP main, 12MP ultra-wide, 5MP macro, 5MP depth sensor
Operating System: Ships with Android 10, upgradable to Android 12 with One UI 4.1
Connectivity: 4G LTE compatible

Who is this for?

The Samsung Galaxy A51 is suited for users who want a large, vibrant display and versatile photography options without flagship-level performance. It works well for students, casual users, and those upgrading from older budget phones. Compared to newer Galaxy models, it lacks 5G support and a more powerful processor but still handles daily apps and media consumption effectively.

Pros & Cons: Pros Cons Large Super AMOLED display with good color accuracy. Processor is mid-range, which may struggle with heavy gaming or intensive multitasking. Versatile quad-camera setup for varied photography needs. No 5G connectivity, limited to 4G LTE networks. Expandable storage via microSD card (not variant-specific but typical for A51 series). Plastic back and frame may feel less premium compared to glass designs.
Why refurbished?

Choosing a refurbished Samsung Galaxy A51 is an eco-conscious decision that extends the life of a reliable device. Each pre-owned phone on Back Market undergoes thorough testing and quality checks to ensure it meets high standards. Learn more about our quality standards.
