Apple's mobile phone calls have sound to send information, but there is no sound. Put on headphones and there will be sound. Why?

1, in this case, this Apple phone enters the headset mode, so only the headset and speaker can make sound.

2. Adjust the volume to see if the headset logo is displayed. If so, the headset mode has been entered.

3. Refer to the picture below. Apple mobile phone enters headset mode:

4. Apple's mobile phone is not plugged in. Try the following solutions when entering headset mode:

1 Restart the phone and try it.

Plug and unplug the earphone hole of the mobile phone quickly and repeatedly with the earphone until the earphone mode is released.

3 Wipe the earphone plug and mobile phone jack with a fine cotton swab dipped in alcohol (the plug or jack may be oxidized).

4. Use the earphone access interface, turn on the ipod to listen to music, then press Pause, press home button to return, turn off the iphone (without using other third-party software), unplug the earphone, and then turn it on.

5 If it doesn't work after several unsuccessful attempts, press and hold power home for hard restart, and then unplug the headset when a white apple appears to release the headset mode.

If the above methods can't solve the problem, it is recommended to bring your mobile phone and invoice to the nearby Apple Service Center to solve the problem.
