Shoot like a pro, with incredible details at 8K resolution and smooth action at 24 frames per second. It’s the highest resolution video available on a smartphone. Witness the fastest chip ever in a Galaxy. With a 5nm processor onboard, you get seamless multitasking and hyper-fast content streaming. The new battery in the Galaxy S21 Ultra 5G isn’t just big. It’s got the brains to match, intelligently learning your app usage to optimize power consumption. Get the power that outlasts the day even in 5G.

It takes good pics which is why i bought it. It is a nice phone. I hasd a little bit of a hard time getting everything set up, but that was probably operator error and not the phone. All in all im happy right now with it. only had it 1 week.

nice phone

I like everything about the phone. It is easy to use. I have always liked Samsung Galaxy phones.

I would highly recommend!

Charger was not even included and now I have to go and spend more $

Samsung has no charger

I received the malfunctioning phone, tested with 2 different carriers. After that, sent it back for a refund, and seller said that I send him a different phone. Had to call customer service with no luck. Stay away from this seller
