[This review was collected as part of a promotion.] I went from an S10 to the S21 Ultra 5g and the camera on the S21 Ultra is so much better not to mention I can actually zoom in and take pictures of the moon!
I would recommend this to a friend!

[This review was collected as part of a promotion.] I've had the phone for a month now, and after playing with it, and going through the settings, trying different things, I really don't feel like it's much of an upgrade over my old Note 10. The camera leaves a lot to be desired. The glare when shooting into any type of light situation is ridiculous. I've researched online, and apparently, there are quite a few people having the same problem. Other than that, I like the OS, and the chipset is fast.

Great phone!!!

[This review was collected as part of a promotion.] I came from an Apple Iphone X. It was really a terrible phone from Apple. Was tired of the phone being slow every year due to updates which purposely slow the phone down so you can buy a new one. With the Samsung S21 Ultra it is the best phone I ever owned! Pictures come out great, system is stable, can multi task, not 1 problem and I have had this phone for over 1 month. The screen resolution is awesome and you can modify the phone the way you want. Everything just seems to work. Has a good sound system too. I highly recommend Samsung and this phone!

Best Phone Ever!!

[This review was collected as part of a promotion.] I bought this for my 40th birthday and this has been by far the best phone I have ever owned. I've owed several Galaxy phones and a couple of iPhones, but the S21 Ultra beats them all!

Lots of Upgrades
on September 1, 2021

[This review was collected as part of a promotion.] I upgraded from a Galaxy Note 8 which I loved. I was nervous about going to the S21. However, I have been pleasantly surprised. The features are familiar to me and I don't miss the SPen- although I do still have one and have tested it with the S21- works just fine.
The fingerprint scanner never works on the first try. It usually takes anywhere from 2-4 attempts and that's frustrating. I finally just turned it off and use a code. The other problem is accidentally turning on Bixby, who will start talking at an average volume even if I have media sounds turned down and volume set to vibrate only. I don't use Bixby and would love to just disable it so I can't accidentally turn it on.
The camera is great. Photos are clear and vibrant.
It came with a bunch of apps pre-installed that I immediately uninstalled. Games and stupid stuff.
The screen is bright and clear and sharp. Performance is great! I have not encountered any bugs. Overall I really like it!
I would recommend this to a friend!

[This review was collected as part of a promotion.] I pre-ordered this phone, replacing an S20, I believe. Overall happy with the device. Disappointed that the battery doesn't last a day. A few other software issues, but not sure what they are related to.
I would recommend this to a friend!
