What happened to the sudden silence of Samsung note3?

If there is no sound in the mobile phone, it is recommended to follow the following steps for troubleshooting and handling:

1. This may be because the option to turn off all sounds is set. It is recommended to turn off all sounds through phone settings-(My device/device)-Auxiliary functions-(Monitoring) and uncheck it.

2. Check whether the phone is in mute state, set-sound-volume, and try to turn up the volume.

3. If it is invalid, please back up data (contacts, multimedia files, etc.). ) and restore the phone to the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the nearest service center for inspection by the engineer.
