Model Name: Asus Rog Phone 2 Firmware Version:10 Rooted or not: No Frequency of Occurrence: few times a week. ======================================== So sometimes my Asus Rog Phone 2 is suddenly stuck in Head phone Mode. Im not doing anything special when it happens. But what I noticed and am 100% about it is that somehow my Cover is the reason for it. When it's stuck and i put my phone put of his cover it doesnt stuck in headset Mode anymore. My Cover is magnetic and this might be the reason for it, i dont have any water inside or like dirt in the aux. It just needs a few seconds to be free then. I just wanted to show this in case some other people are having the same issue. I tried so much like Apps that force the Sound to speakers and so on.
