Problem Oneplus 3T OTG storage is permanently active


Good evening !

I have an OP 3T.

I use headphones a lot (I have BT now, but the quality of any headphones I own leaves much to be desired) and I would like to switch to USB type C headphones.

I know that by default, on 3 and 3T, the OTG storage is only activated for 10 minutes.
I managed to find a tutorial that keeps it permanently active.
If so, could I use usb type c headphones?

Has anyone tried?
