How to resolve sound from Samsung Galaxy S8 and S8+ for muting automatically
Samsung had been notified recently that some non-compatibility third-party applications may cause muted sound phenomenon on the device.
If new third-party applications have been installed recently, we recommend to check your device in Safe mode or after uninstalling it.
To check your device in Safe mode, follow these steps:
Your device will power up in Safe Mode
While in Safe Mode, check your device with the third-party applications disabled. Identify which application is causing the issue and uninstall it.
Press and hold the Volume down key to activate Safe Mode
Safe Mode is activated
Third party applications are disabled
