I have Samsung galaxy s3 neo.
OTG cable and otg ir remote device worked fine and after few days it won't detect my otg cable and otg ir remote device until I pull otg cable little up and hold it and some time when I connect otg cable it says usb connector connected and usb connector disconnected and repeat that many times.
How to fix this?
I tried using another otg cable and still have problem.I don't have problem with usb charger.
Data transfer between PC and Android is working fine.

Could be a broken solder joint on the connector in the phone..
You would need to open it up and resolder the connector..

This is a VERY common problem due to frequent use/abuse of the usb connector/cable..

Yep..
It is.. I guess they have been banned before as their posts don't show up anymore..
