I ran that same app on my Tab4 as well, unfortunately I wasn't able to understand everything the app told me so I concluded OTG support on the Tab4 was inconclusive =P
Considering OTG is supported on the other Galaxy Tab devices, what reasoning would Samsung have to not enable this feature on the Tab4 7.0? Especially if the hardware is the same (or very similar) it just doesn't make any sense to me why they wouldn't give the Tab4 7.0 OTG support as well. It's actually very frustrating in 2014 that this Tab doesn't support OTG. I am almost considering returning it solely for this reason (I haven't yet, because I'm very pleased with everything else the Tab4 has to offer).
My cheap, Chinese sub $100 android ICS tablet I bought last year had OTG support! What gives Samsung? I sort of expect more from a major brand like Samsung.
