S3 otg not working

[Aziel Oropeza]

Bought a new SanDisk Ultra Dual usb 32gb for my S3. Both SanDisk and Samsung agree that it is OTG compatible. But when i plug the usb on my phone, nothing shows. I've tested on several HTC phones and even a Galaxy S5 and it works there but not on my S3.

Phone is rooted running on stock 4.4.4 kitkat rom.
