What is the earphone icon on Oppo mobile phone?

1. This is an OPPO phone that has entered headphone mode, so the headphone mark is displayed on the upper right corner of the phone.

2. The headphone mode is automatically switched. When the headphones are plugged in, the headphone logo comes out, and when the headphones are unplugged, the logo disappears automatically.

3. It may also be caused by the failure of the micro switch of the headphone jack, that is, the headphone has been pulled out, but the switch did not turn off in time.

4. You can try to quickly unplug and plug in the headset several times to see if the headset logo disappears, or restart the phone.
