My phone/tablet starts reverse charging when a USB flash drive or OTG cable is connected

My phone/tablet starts reverse charging when a USB flash drive or OTG cable is connected

Problem:

The phone/tablet starts reverse charging when connected to a USB flash drive with an OTG cable.

Cause:

After you manually set the phone/tablet to data transfer mode (or another option), the system automatically switches to the reverse charging option. This is because the phone/tablet needs to supply power to the USB flash drive (or OTG) so that the USB flash drive can work properly. This is normal and does not affect the data transfer.

Solution:

To transfer files between the phone/tablet and the USB storage device, connect them using an OTG cable, go to Files > Local , then select USB.
