Customers are saying

Customers enjoy the Galaxy S21 Ultra 5G 128GB's impressive camera quality and long battery life. Positive feedback also highlights the large screen size and smooth 5G connectivity. However, some users find the phone heavy and expensive, while the lack of expandable storage is also a point of concern for a few. The phone's ease of use is also frequently praised.

    No instruction book. I had to look on YouTube to see how to power off. None of my passwords were auto entered like before so that's a huge mess. Too heavy and too big. Battery seems OK. Luckily, I got an $800 AT&T credit for my old S9 paid monthly so the new phone with 256k costs me only about $6 a month. Meh. Maybe I'll like it better with time but it's still too heavy.

    No, I would not recommend this to a friend

    With an exception of removable battery, headphone jack, micro sd card slot and a finger print reader on the screen that makes screen protectors and cases difficult to find that i like, this is a solid phone. I hope the mext few generations wpuld move the fingerprint reader to the back like the S9 and bring back the headphone jack and card slot.
