I am using S8. Using the phone in perfect condition. As soon as I click on update Android version 9. My phone is spoil now!! My screen turns bright GREEN with a black patch on top and its flickering badly. Please fix this issue althou it seems like they do this updates code error on purpose so we have no choice to buy new Samsung phones. Its their dark way of these companies pushing buyers like us to buy new. Whatever FIX THIS UPDATES back to normal!!
