Samsung

but there is no shutter speed and focus control button in pro mode. I am waiting for this. I am disappointed.

it's available in samsung members app

M series have core version one UI ,But A series have full version of one UI. Because it takes some time to provide updates.

Samsung A50s has left only one major update, because samsung works to give one UI 3.0 with android 11.Please wait for that. It will come mid of November i think.

A50s have 2 major updates 1st one one is already got with android 10. I think samsung give android 11 and one UI 3.0 update, because it takes time to give e update
