My problem is this:
When I have my headphones connected to the bottom of phone. I sometimes and suddenly get maximum volume! Without touching or doing anything but listening to music. It also skipps a beat whenever I open or close an app. (All the time, every time) This however, never occurres when I use the side fan mount.
Sound problems
Please check behavior with safe mode
Press and hold power key for few seconds than tap and hold on switch off for few seconds you will see option to entre safe mode press yes and see if same issue exists there
To exit safe mode just restart your device
Did you try clearing cache of your audio player? Infont please try that also try to check above steps suggested by ADH and if still issue persist after every try i suggest you kindly backup your important data and please reset your device that should help as this seems like bug triggering by any third party app & it will be a fresh start also no other user has reported such issue like you.
Thanks!
