Best phone I've had to date
on December 30, 2022
Posted by: Matt C
from Fort Worth, TX
[This review was collected as part of a promotion.] From early Android and Apple, this has by far been the best phone I've ever had in my possession. From the daily use, ranging from the camera, emails, and to social media, the S21 Ultra is smooth, fast, reliable, and always ready for the tasks at hand.
I would recommend this to a friend!

Phone freezes and restarts on a regular basis
on October 19, 2023
Posted by: Alex
I bought this phone over a year ago brand new. It keeps freezing and restarting. It happens at least a few times a day, sometimes more. To be honest the camera is the only good thing about this phone. Performance wise, it sucks. I am in the middle of scrolling through an app or using Google maps and out of it just freezes and I have to wait for it to reboot to start resume what I was doing. This is not an uncommon issue with this device. I have read online hundreds of testimonials of people reporting the same thing, so I know it's not just my device. Samsung refuses to replace the phone. Overall it's a mediocre phone if I can't use it since it always crashes.

Great Device with some tiny issues
on April 21, 2024
Posted by: Mohammed
It is a great phone, but from factory I have an issue with AOD, it is always very dim even after doing all the neccessary troubleshooting. Also sometimes I feel that adaptive refresh rate is not working 100%.
I would recommend this to a friend!
