Now the ThumbDV is working on my phone there is one issue left.
If I connect the ThumbDV directly to my phone, it will drain the phone and after 45 minutes the complete solution stops.
I brought some OTG cables but none of them are working.
See my cables and see that none of them charge the phone. ( upper battery icon. )
Is there anyone who knows OTG cables that charges the phone and power the ThumbDV and also tested it?
