How to change the headset mode of Bluetooth headset back to headset mode?

Turn on the phone, click to enter the settings, find the general option in the settings and click, click the auxiliary function in the general interface, then select the audio call mode, and then click the speaker.

Method 2:

If the phone still does not exit the headset mode after unplugging the headset, it is likely that the headset switch on the phone is invalid, which makes the phone unable to correctly identify whether the headset is unplugged. It is recommended to repeatedly insert the earphone to see if it can be restored, or thoroughly clean the earphone hole.

Method 3:

It is also possible that the mobile phone is damp during use, and the internal parts of the mobile phone are in poor contact due to water vapor. In this case, you can use a hair dryer to blow into the earphone socket. If the above methods do not solve the problem, it is recommended to back up the mobile phone data before going to the local repair shop for repair or inspection.

It should be noted that this answer applies to most mobile phone models such as Huawei, Apple and vivo.
