●The Galaxy S21 Ultra is the best phone I've ever used, also I refused to switch to the newer models. •The main reason is the slim design, with the rounded corners compared to the newer models with the square corners that makes them bulkier. •The second reason is that it still holds well in performance and and camera compared to the newer models untill today, but its heartbreaking that this device has received its last major update. Anyways this phone is still a beast, it can be compared with the latest iPhone and still catches up and this thing surprised me, like a phone from 4 years is equal to the iphone flagship of this year. •One big surprise, Even after four years of use, the Galaxy S21 Ultra battery still offers me sometimes a full day of use with a single charge. The battery quality is impressive. I get 5 to 6 hours of screentime on a single charge. ●After I refused to switch to a newer model, now I'm forced to buy a newer one. •first reason is that this phone's journey has ended, with getting it's last major update. •also the S21 ultra didn't get all the ai features from the one UI 6.1, or one UI 7.
