OTG issue Oneplus 3T

[Darkmaster3]

Hello. Since one month my OTG on my Oneplus 3T isn't working anymore. It just doesn't recognizes the OTG device.
Moreover the phone always thinks an OTG device gets connected ( i noticed because of the app "Otg Troubleshooting"
the checkmark for an otg device is connected is kind of changing its mind all the time...


this process always wakes the kernel up ( I know because of Better Battery stats in kernel wakelocks "fusb301_otg_wl" is listed on the top with 100% ) so the system can´t get into deep sleep, in further consequence the battery is very weak.


I already did a lot of factory resets ( even wiped everything with TWRP ),
wiped the cache several times, cleaned the port and tried older OS versions...


So I am quite sure it is an hardware issue, but is the issue just und the USB port or might it be on the mainboard aswell?

Since the first day of the device i noticed that th little tap in the port is very very slightly bent ( I don't know if this is in association with this problem )

If it is the USB port for sure I am gonna fix it my own so I doesn't have to send the device to service center (guarantee) because I need the device a lot for business...

Does anybody know what to do? or has anybody an idea of how to solve this problem???
Regards, Emil

Have you tried with another OTG connector? Or have you plugged your OTG cable into another device? Verify if your OTG cable works properly first.

If it is a hardware issue, I suggest you send the device into repair instead of doing it yourself. One guy here did it by himself and the device refused to boot up. I wouldn't take a risk as opening the device up would void your warranty (if still applicable) and its definitely safer letting a professional doing it.

yes i tried 3 different otg devices (so the cable is working for sure)

Yeah but do you think it is just the usb port or might it be another hardware problem aswell?
