My S21 ultra lagging and extremeframe drops
I have tried everything the phone in ins warranty I took it to the service centre and they said it software issues after then they installed new firmware on it but it didn't helped anything now they are refusing to acknowledge that my phone has problems and fix it
reproduce the issue and report to samsung members app > get help > error report **report 1 issue per ticket**
what is the phone's model number and the software version running?
are you using a 3rd party launcher or 3rd party theme/wallpaper?
