It's the moment of truth: I have an OTG cable and have just booted up the other old tablet…
First OTG cable (from pack of three, obviously…) - does not charge through it, but works to connect USB device to tablet. Not good.
Second cable - same again.
Third cable - same shit.
Weird. I would have thought it would allow a USB device to connect OR charge, but to not charge AT ALL through the OTG cable is an unexpected behaviour.
That tablet can consider itself binned-off.
