[This review was collected as part of a promotion.] Love the camera! Had an issue with phone and was able to get it fixed in a timely manner. The phone does everything I need plus so much more that I haven't had a chance to figure out!
I would recommend this to a friend!

Love the camera!!!

I bought this at launch, because I read reviews from tech sites talking about the camera, and I knew it had the newer 5G modem in it. And it does not disappoint. With the original telephoto lens on the note 20, there was a lot of shakiness when zoomed in past 30x. On the s21 ultra, I can zoom in all the way, and while there is some instability, which is to be expected being zoomed in so far, the AI assisted balancing works a lot better for getting those zoomed in photos at a clear resolution. I have not been disappointed with the camera at all. And the 5G improvements made in the modem are extremely noticeable. Much better reception with it.
I would recommend this to a friend!

Best Smartphone I’ve ever own.

Expertise:Expert
Had this phone since March and I’m still amazed by the fact that I always find something new about it. The design is a sight to behold, the cameras are extremely versatile, the performance is unparalleled, the overall experience has been great to me. This phantom silver s21 ultra solidifies my decision as a Samsung customer. Highly recommend.
I would recommend this to a friend!

Unhappy
on June 10, 2021
Posted by: Champ
[This review was collected as part of a promotion.] No feature to keep the screen on during a call. Frustrating when you are on Bluetooth and do not have instant access to screen to toggle mute button.
No, I would not recommend this to a friend.

When u guys decide to come up with adding the sdcard card slot again AND increasing the display size above 6.9, preferably 7.0" then and only then will I buy a Samsung phone again. Till then you cannot even compete nor beat an iphone!!!

Needs micro SD slot

[This review was collected as part of a promotion.] Samsung needs to bring back micro SD card slots in its phones. Other than that it is great. But this will cause me to look elsewhere for my next phone.
No, I would not recommend this to a friend.
