[This review was collected as part of a promotion.] I've had the phone a couple months and still finding great new features. The camera is amazing. I've always had the note series but glad I made the change.

With 12 GB Ram this is Great

[This review was collected as part of a promotion.] I traded my S9+ for the S21 Ultra. All the apps seems to work better and smoother with the new S21. Some were suggesting that I go to the I12 and knowing the difference in the ram I stuck with Samsung and pleased that I did.
I would recommend this to a friend!

[This review was collected as part of a promotion.] I bought this just prior to taking a bucket list vacation. The pictures this phone took so exceeded my expectations that 2 days into the trip i put away my camera and just used the galaxy s21. I would recommend this to anyone.

Best Phone Ever!

Expertise:Expert
[This review was collected as part of a promotion.] So, hyperbole aside, the S21 Ultra (512 GB) is the best phone I've ever had. Camera, battery life, speed, resolution, display, and storage, it has it all. The features and every day usability of this phone absolutely make it the best.
I would recommend this to a friend!
