    • High battery drain
Nearly 400 and battery drain is fast + screen scratched. Its below amazon refurbish standard of excellent. It is like good, not excellent at all. Not Worth the money. I feel deceived. Bought 3 excellent phones and all fine from other sellers. This one's a good condition. Not even close to excellent. Below 80% battery. I buy 3 refurbish from other seller and all have better battery and perfect screens. This is unacceptable for price. I am still deciding refund or ask for fair discount. ... show more

    • S-21 Ultra 5G (SM-G998U) 256GB 8GB
The phone is worth the price for the basic functions and the camera by itself. I bought the version with 256GB of storage and 8GB of RAM. With RAM Plus I can have up to 8GB of virtual memory on top of the physical 8GB. Picture quality is up there with some low-end Digital SLR's, and there are apps on the Google Store that give you control over all sorts of settings to make your pictures more like a mid-range to expensive D-SLR. The rear camera has 108 Mega Pixels worth of sensors and the front (screen hole) camera has 40 MP. Both sensors take excellent low-light photos. Definitely the best cell phone I have owned, to date. A vast improvement over the Motorola's and Nokia's of the 1990's ... show more

    • Amazing phone
Great phone. Only issue is the camera doesn't seem to work correctly. When I turn it first on the image is blury. I either have to zoom out or zoom in to take a clear picture.

    • Almost new
It appears that Amazon send me a new one by mistake, was not in the original box or with the actual charger, but I was surprised by the condition of the phone, no visible marks or problem in functionality. Thanks, Edge Cellular
