    I hate to change phones and learn new patterns, but this has been worth it. A fairly easy learning curve, and a great performer too.

    Not bad if you can handle the strange UI imo

    The build quality is solid even though the plastic does take away from the premium feel of a flagship. I had to return this device because after years of using stock Android I found the Samsung UI to be a little odd. One week without my Pixel 5 and using the Galaxy S21 5G instead felt like a week at an awkward relatives house. The camera seemed as good as the Pixel camera and the color selection is amazing. Just keep in mind that the Samsung UI takes some getting used to if you are coming over from a Pixel, Motorola, Nokia or other stock or near stock Android device.

    I love this phone. It's very easy to navigate. I mostly try to stay in the Samsung Galaxy family when I buy phones. They have great quality phones and they're affordable.

    It's a good phone. Minus the overheating issue that I encountered. Had to buy a different phone since the 21 is the newest device and there's nowhere else to go lol. Still a great phone overall

    Great phone, but has way too much bloat even as the unlocked version. There always seems to be something going on in the background with Samsung's flavor of Android.

    Acceptable smartphone

    For the original retail price of the phone, it seems lacking compared the previous gen. Definitely would not purchase it at its original price. Nevertheless, as a smartphone, it is fine. Aesthetically it looks beautiful, though the feel of the plastic back panel is somewhat disappointing compared to something like Pixel 3A polycarbonate. It is something I got used to. I have been using it daily and I can get maybe a day of use before a charge is needed. My usage of the phone is usually light browsing and gaming. Otherwise it sits idly. The battery does discharge quite noticeably by itself compared to my previous phones but not in a way that I would be very concerned.
