The device has introduced a charging port anti-corrosion solution, and some non-standard USB flash drives and headphones cannot trigger the insertion event. It is recommended to turn on the OTG switch in the settings to force triggering OTG device detection.
To turn on the OTG switch, please refer to the following steps:
1. Go to the [Settings] APP on your phone;
2. Select [Additional settings];
3. Tap [OTG], and turn on switch before connecting the device you wish to use.
Note:
Turn on OTG to connect your device directly to other devices using USB. This feature will automatically turn off after 10 minutes of inactivity.
