How to turn off the phone when it becomes headset mode?

Taking Huawei P30EMUI0 as an example, the method of restoring the normal mode of the mobile phone is as follows:

1, the sound of the mobile phone changes to earphone mode, which usually appears because the mobile phone has an earphone plugged in. To return to normal mode, just unplug the headphones.

2. After unplugging the headset from the phone, it is still in headset mode, so you can turn off the phone and restart it.

3. The phone is still in earphone mode after being turned off and restarted, indicating that the chip in the earphone hole of the phone has not rebounded. You can try to insert the headset into the phone repeatedly, and the chip can return to normal mode after it bounces back.

4. Because there is a foreign body in the earphone hole of the mobile phone or the jack is oxidized, you can use a cotton swab dipped in alcohol to rotate and wipe the earphone plug and the jack of the mobile phone, and then re-insert the earphone into the mobile phone and pull it out.

Taking iPhone11IOS13 as an example, the methods to restore the normal mode of the mobile phone are as follows:

1. Only when headphones are plugged in will the estimated system card be displayed. Restart the phone.

2. Turn on the music player, let it play in the background, enter the sound settings, and select SMS sound to cancel the headset mode.

3, click on the audio call mode and check the speaker.
