How to turn on the hands-free function of oppo mobile phone

When making a call, click the microphone icon in the lower right corner of the call interface to make a hands-free call. If you don't plug in headphones when playing music, it will be played by the speaker by default. Please operate it.

The steps to open the WeChat speaker are as follows:

Only when the mobile phone supports the smart call automatic switching function can the call be automatically switched to the hands-free or handset mode.

When talking, pick up the phone close to your ear, and the hands-free will automatically switch to the receiver.
