There is no sound when the phone calls, but there is sound when watching the video. Why?

The most common thing is that the mobile phone is turned on in silent mode, with only vibration effect. Just change the settings.

If the speaker of a mobile phone is damaged, it will usually be taken to a mobile phone repair shop for inspection. It's best to go back to the factory for maintenance to prevent the shop from tampering.

If there is something wrong with the mobile phone software, you can download the latest installation package or restore the factory settings. If it is still an old problem, it is recommended to return to the factory for repair.

Some mobile phone speaker settings will minimize the multimedia sound, so just set it yourself.

If there is no ringtone during a phone call, it is recommended that:

Please check whether the phone is in mute or vibration mode. Operation: standby interface-pull down the screen top curtain-find the sound icon-click the icon to switch to sound mode.

Adjust the ringtone size: Settings-Sound-Volume-Ringtone (call volume), slide to the maximum.

In the settings menu, check whether the ringtone plays with sound. If there is a sound, it is recommended to try to change other ringtones.

Restart the phone.

If your phone supports the function of turning off all sounds, it is recommended to go to Settings-Accessibility-Turn off all sounds-uncheck it.

If it is invalid, please back up the information (contacts, text messages, pictures, etc.). ) in your phone, and then restore the factory settings.
