When I first used my OTG, I accidentally removed it without unmounting it. Ever since then, I kept receiving a notif about restarting whenever I mount it on my device. I thought formatting both my phone and the OTG would solve it, but I was wrong. My System UI still sends me the same msg that goes "Restart your phone. A USB storage device was removed unsafely. To prevent your phone from restarting unexpectedly, save unsaved data and restart now."
