How to cancel the headset mode of Samsung mobile phone

If "Headphone Mode" is displayed on the phone screen, please operate:

1. If the phone is currently plugged in, please unplug it.

2. If the earphone is not plugged into the mobile phone, the mobile phone has this prompt. It was suggested that:

1). Turn off the phone and restart it.

2). Eliminate software factors: backup mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

3). If the problem still exists, please take the purchase invoice, maintenance card and machine to Samsung Service Center for inspection.
