Great phone

[This review was collected as part of a promotion.] This phone is wonderful. Upgraded from N20U. The only feature it is missing is SD card slot but internal storage 64GB only half full so not that big of a problem for me. I rarely used S Pen with Note phone but I like having the option to do so. I have had the phone since launch and have notice a decline in battery life to be expected of course. Camera takes great photos. Friends with the fruity phone accused me of downloading my 100x moon pictures off the internet even though they watched me take the picture!
I would recommend this to a friend!

Great Phone

[This review was collected as part of a promotion.] I moved from the Note 20 to the Galaxy S21 Ultra, and the only think I dislike about it is that it does not come with an SPen like the Note does. I didn't realize how much I would miss that pen. However, the device is compatible with the SPen and I will likely purchase one.
