Hope i find someone here who can help me.
Yesterday i downloaded and installed Android 10 on my M30s. Once phone started i found screen flickering (it's moving evey time i do anything and not stable), for example when i open whatsapp the screen is divided (doubled) scrolling is bad, same with facebook, some videos are not stable too in terms of display. navigation bar keeps appearing up, and many very annoying issues.
So my main problem is in the display.
Note: i got a screen problem before and had to have the screen changed but didn't face such problems before android 10 update.
Thanks to advise with what may help me fix this problem. I want to know if it's a hardware or software issue. Samsung center where i live **bleep** and i had to go before to someone to fix it for me. He told me today that it might be a software problem so he will put update 10 again (without removing the one installed now), and says it's the original one from samsung, but i fear that would mess up with the phone software, as i also have doubt that this may be a hardware problem not matching with the new update. (in this case what should be done too ?)
