These all must be due to some bugs after oneui 3.1 update.

[Dr_Interchupipi]

No bugs .. worst unoptimised software everytime

[Dr_Interchupipi]

But then also ... I must have to tell that Samsung recommends to install software via smart switch and pc or from service center firmware flash to avoid software loop holes formation which basically comes if you simply install software via wifi or mobile data .. because Samsung provides nonA/B grade partition ota ..not like other company

[rap1021]

Can you explain A/B grade partition bro..???

[Dr_Interchupipi]

A/B type of partition benifit is that if the software not installed correctly then you have a second chance to revert back to check issues but in non A/B partition you can't .. and in Samsung they provides non A/B partition from long time ... it's not new ..around 2013 or 14 there was a big backlash of Samsung that every device got bricked after software installation... then Samsung introduced kies needed to detect bricks and firmware installation... but kies was not software friendly..then Samsung introduced smart switch.... and Samsung use odin itself to flash firmware as it's Samsung official software which they recommend

Ok so if the software didnt install correctly on non a/b partition phones, then what..???

[Dr_Interchupipi]

Possible if you are using fluctuate network..then software loop holes can produce..please read my full post above

[Dr_Interchupipi]

Software loop holes can create 1000 of issues in device..like battery drain faster , standby battery drain , heat lag ,poor camera ,poor gaming performance etc .. i always use smart switch to install software bro from 2014 to 2021 i am using Samsung...practical phenomena is never use wifi or mobile data to install software in any Samsung device because anytime anything can happend even display also can gone forever as many users faced before just after software installation

So if maybe my phobe has software loopholes, then how can I fix it, flashing via odin..???
