Why can't viovy30 connect otg and MP3 with USB flash drive?

The OTG function cannot be used on the mobile phone. You can check it according to the following methods:

1, check the OTG settings of the mobile phone.

Go to phone settings-more settings -OTG (or settings-other networks and connections -OTG) to see if the OTG function is turned on. If this feature is not turned on, you will not be able to connect OTG devices. Please turn on the OTG function switch, and then connect the equipment for testing (Note: OTG will automatically turn off if it is not used for more than 5 minutes).

2. Compare and test OTG jumpers

Connect the OTG jumper to other mobile phones for comparative test to see if it can be used. If your mobile phone and other mobile phones can't use the OTG jumper, it may be that the OTG jumper is abnormal. It is recommended to replace other OTG jumpers for connection test.

3. Compare and test devices connected to OTG

Connect MP3 to other devices (such as computers) to see if it can be transmitted and used normally. If the connected mobile phone and other equipment (such as computer) can't be used, the OTG equipment may be abnormal, so it is recommended to replace other OTG equipment for testing.

4. If the above methods are ineffective after operation, you can take the mobile phone and purchase certificate to the customer service center for testing and processing in time. The address of the customer service center is: enter the service outlet of vivo official website /vivo Mall APP-mine-or the webpage version of vivo official website-slide to the bottom-service support-service outlet query-select provinces and cities to query the address of the customer service center.
