How to fix usb port problem?

[Pavlex4]

I have Samsung galaxy s3 neTG 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.

Re check developer's options?

You mention no problems with the USB charger--but what about the data transfer connection with your PC if you connect via USB? If it's constantly connecting and disconnecting to the PC, then I'd suspect some problem with the port--specifically with the data transfer contacts (which are separate from the charging contacts).

Hmm. The fact that you have to adjust or jiggle the plug still suggests a problem with the connection. Use a can of compressed air to blow out the microUSB port, in case there's some debris in there getting in the way.
