Hi there. I have Sony Xperia z3 (Android 6.0.1) phone and OTG USB adapter. While It works well with some USB devices (e.g. USB flash) it does not work with others, for instance OBDLink SX USB.
Meantime Samsung A3 2016 + same OTG USB adapter + same OBDLink SX USB works well.
Tried two different adapters - same result.
What is the reason? Does Sony support USB flash drves via otg adapter only?
