    Took advantage of the holiday sale on the phone. It is fast and performs well, much nicer than the old samsung phone we had. It already survived a few falls unscathed. Love the 5G and WiFi 6 support. Appreciated the helpful BestBuy staff helping us transfer the contents to the new phone. Took one point off because samsung no longer supports an additional sd card or a headphone jack.

    Decent (not completely clear) case

    I'm going to split the review in a couple of categories. Aesthetics: The case is not completely clear. It has a smokey tint, but it does compliment my violet phone. I'm not actually convinced it might look well with white, for example. I think that may have been done to avoid the "yellowing" effect that most clear cases suffer from. When you look at it from a certain angle and from a certain light, it does show some light reflection that looks kinda like a rainbow. I don't know of what the exact term for it is. It might be my hand grease. But there you go. Grip: The phone's back is ridiculously slippery. I do think that the rubber grip around the casing does compensate for it, however. I'm not sure if it's Samsung or just shortcoming of the type of plastic used. Protection: I've dropped my phone face first the other day and my phone is still intact. I've also dropped it a couple of times and landed around the corner and the rubber "railing" around the case seems to be absorbing the impact very well. And of course it is raised a couple of mm so the screen isn't flush with the floor. That said, I don't think this is quite a mouse or otterbox case, but for what it is, it provides decent protection from everyday drops. I wouldn't be conducting any experiments like dropping it from a crane, or tossing it up like a volleyball serve. Specially since I paid for my phone out of pocket. I think for it's price, $40 it could be better. I wouldn't pay anything above 25-30. Like I said, it isn't completely clear which kinda defeats the purpose of a clear case.

    I've only had my new phone for a few weeks but I have to admit, other than getting use to a new phone it was a good buy! I needed one as my Galaxy S7 was getting a little tired. I would definately recommend the up grade. I'm not one to have the newest phones at all times but I love the Galaxy series of phones and at least for a hot minute I do. I love my new phone.

    This phone is pretty great, it is very responsive and I haven't had any storage issues at all after bringing all the stuff from my old phone onto it. The color is also really pretty. The camera is pretty good quality, got some good pictures outside and on some mountains so it handles pretty well.

    This new Galaxy S21 5G is a great phone especially for the price. The scrolling is amazing, no loss or blurring of picture. Sound is great and the camera is top notch. Still working thru many of its features but really like it. It is a well put together and thought out phone

    I adore this phone. I have had an iPhone for many many years. I tried to switch to a Samsung twice before, going to the Galaxy S 9, and then the Galaxy A50. The S 9, I didn't really give too much of a chance if I'm being honest. But the A50, I did not care for. However, this phone, I love so much! It is so easy to use and I just love the features it has.
