galaxy s21 ultra

I sideloaded the one ui 4 betas via adb then did the same to install the official release. What do I do to be able to go back to my phone being able to download the updates without wiping it?

So, I noticed after I updated to one ui 4 (android 12) the camera app got a lot softer and more.. *blurry* with the 39x and 100x zoom. Pics attached for reference I don't even need to explain which is which anyone else with similar issues?

My 108mp camera is not focusing on things that are far away.If I give the phone a heavy shake ,its back to normal till the phone is stationary for a longer time.Seems there are many with the same issue. Am going take it to samsung today.

I thought we should have a thread dedicated to Canadian users, our model is different enough from the US one (U) to warrant a separate section. For starters, I haven't seen any mention of the May patch AUDA on any of the carrier forums (Telus, Fido, Rogers, etc) nor anything on the Samsung...

Found this video and it is very interesting. S21 Ultra is losing almost in every situation. Damn…

Hello, I live in the US but purchased the Hong Kong model S21 Ultra, model SM-G9980. This model is using the Snapdragon chip set, and supports dual physical SIM. It supports LTE bands 2,4,12 yet it has not been aggregating any of the LTE bands in areas which I know a US model would. As far as...

I am really interested in getting the S21 Ultra but need a dual sim phone for my work number. Speaking with Samsung support, the only version of the S21 Ultra that is dual sim and has the Snapdragon 888 is the Chinese version. Looking online I can find some online that ship to Canada. What...
