bro s8 is really great device which fulfill all of the functions...from strong biometric to performance..... remember os update allaways not have advantage......better replace your device display or you can buy maximum to s10+ but by mistake don't buy recent bogus s series ...... i am using s9 and I also faced same issue in my s9 ... before 1 year I replaced it .... s8 ,s9,s10 are king forever...now a days neither samsung can give iris, hrt sensor not can make a unique device like s8 which need approximately 860 degree temperature to curve
