Great, I will test it at home

edit:
so, I tested it, but i didn't success :/ I made 1,2,3 point, now phone looks that it is charging, so i re-plug flash disk into phone, but nothing happen...
I tried it with this app https://play.google.com/store/apps/d...exususb.viewer, with in buil file manger, with ES file manager.
I am on stock, only rooted, rom...
What I am doing wrong? Or it isn't just working? :/

Re: [HOW-TO][TRICK]USB OTG ON S3Mini
wonderful and finally an easy way (it's the first one also) ...but I didn't understand why we have to plug it to power first (steps 2,3)?

Hey!
Great news, thank you for sharing. I've been wanting this for a while.
Could you please make a logcat dump of the phone while doing the process?
We might find something of interest.
Greetings

Ok, i tried almost every USB device that I have, but without success :/... But if I look in your attached txt file, I see there this: "build.display: DMod based on BenzROM v4", I really don't understand what about the file is, but I thing, that this mean that you are using some moded ROM, not stock rom, right? So I thing that there should be some mod/tweaks in this moded ROM which enables for you OTG

Very interesting information.
Looks like the phone does not provide any power when OTG cable connected.
Theoretically, it is possible to create small app that will give power to USB (phone will work as charger)
