idk about you guys but it seems like a lemon phone
seems like a hell of a lot more failed than just the screen, likely ram as well.
samsung update bullstuff could just as easily cause similar issues
you signed up for low quality bullstuff when you signed up for samsung
good android phones include: most phones running stock android especially google, if youre not adverse to flashing roms then custom roms are a viable option.
while flashing options are limited on this brand xiaomi is an underrated phone brand imho, surprisingly cheap with incredibly good specs and build quality, the total opposite you would expect from a chinese company.
oneplus is a bit hit or miss but when they do hit they hit extremely well. (oneplus 1 and 4)
LG is starting to go in the direction of samsung in that theyre doing stupid stuff but theyre still good today.
theres my 2 cents on phones, your current phone is forgeted and i wouldnt recommend trying to repair it.
