What if unable to enable USB OTG?

Update Time: 2022-10-24 17:33:15

Problem phenomenon:

The OTG switch in the phone settings is gray and cannot be turned on.

Models:

The earphone jack is a Type-C port.


Cause analysis:

The earphone jack of this type of model is shared with the USB port. In order to quickly identify the earphone, it is designed to automatically turn on the OTG function after connecting the OTG cable. At this time, the OTG switch is turned off and grayed out.


Solution: 

Because the earphone jack of this model is shared with the USB port, in order to quickly connect external devices, it is designed to automatically turn on the OTG function after connecting the data cable or external device, and the OTG switch is turned off and grayed out at this time. This is normal.


Note : 

1. If the OTG function is not used for 10 minutes, it will automatically turn off.

2. For models with an earphone jack, the OTG switch is turned off by default, and the OTG cable will not be turned on automatically. This switch will not be grayed out and can be turned on and off manually.

3. Some models do not support OTG, please refer to the actual situation.
