Hello, i have a problem with my phone after the new update, for some reason all the sounds started coming from the earpiece speaker i have tested the original speaker and its working fine, i have tried a lot of things and still the same problem
Have tried reset settings ? Go into settings then scroll to general >Reset> reset settings
But this happen after the update and you tried factory reset and safe mode still same might have to flash the firmware again. If you don't know how to do that probably have take Samsung to warranty.
