Have us due to the non ersichtichen clear compatibility ordered the OTG adapter, but this does not work on Galaxy Tab II 7.0 / S4 mini, as these devices are not OTG capability, which we found out later. The seller should exclude this in the description.
Equipment is well made, functional but can not be verified, return shipping is economic total loss because vendors only insured package takes what little accommodating, but a shame to blame in this case.
