Apple's mobile phone voice can't be heard, and neither can the receiver speaker. Only headphones can listen, there is no display screen.

There are many reasons why there is no sound in the iphone handset, so we should rule them out one by one. All the problems can be solved except that the receiver module is broken and must be taken to the repair shop for repair.

1. Settings-General-Cellular-Turn it off for a while and try again.

2. Try a forced restart. You can enter headset mode.

3. Setup-General-Restore-Restore System.

4. Upgrade your phone to the next system.

1. This may be because the option to turn off all sounds is set. It is recommended that you turn off all sounds through phone settings-My Devices-Accessibility and uncheck it.

2. Set-Sound-Volume and try to turn up each volume.

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