Customers are saying

Customers regard the Galaxy S21 Ultra 5G 128GB highly for its exceptional camera and video quality, long battery life, and ease of use. Many appreciate the large screen and sleek design, while some find the phone's weight and lack of an SD card slot to be drawbacks. The absence of a headphone jack was also noted as a negative aspect by some users.

    Phone is fine. Im angry that they scheduled sn appt for me to get my info transferredd and then system wouldnt let thectech log in to do it because it was on Black Friday and they were to busy . Why givevthe option for this when on line shopping!!!!! Had i known i would have picked up the phone sooner that day. The tech was VERY NICE and apologetic. Get your mess together Best Buy.
