Hello all,
I was facing issue when I attach my usb drive to my phone through otg that when I'm coping anything to usb it was disconnecting from itself, tried many otg devices and also changed my usb drive and still the problem exists, after too much time search I found strange fix for this problem but worked at last, The fix is to turn on (Airplane mode), I don't know how and why sim cards affect otg but at all my otg works great and coping 10 GB for 1hr without disconnecting issue
Also, make sure that the following apps have no Battery optimization limit: File Manager, External Storage, MTP host, System UI, and also the app you use to copy files. To make this on MIUI 11 go to Settings, Password&Security, Privacy, Special Access, Battery optimization, and then Show all app and make all app mentioned (Not battery optimized)
Also make sure that System UI app has all notification is show and has high priority.
