you are quite right bro. I went our nearest samsung service center. they said my Galaxy A50s needed to software. And then they input a software in my Galaxy A50s. now performance good but not enough. camera performance is too bad. and on display fingerprint scanner doesn't work out of home .
flash your last software from service center... basically it happens if you simply update software via mobile data or wifi and by chance software loop hole comes by that ... it's not process for software update..that's why samsung introduced smart switch to overcome software loop holes....samsung provides non A/B partition type ota software not like other company hence if someone simply update it via mobile data or wifi then there will be chances that the software not installed fully or correctly..if it's like that then device suffer various problems by which this forum is full with ... where actually process is to install software via smart switch and pc, or via odin or from authorised samsung service center as they use odin only for their official purpose
not allaways but if such problem coming then go once ... see bro don't know about other users but I don't take any risk ..because before I saw also ..not only battery.. devices display damaged forever after software update via mobile data or wifi..
