Only recently my phone when it's on like .. but not locked or anything the volume will turn itself down right down to vibrate and continue vibrating until I turn it right up again, but now it seems to turn itself straight back down to vibrate again and its a long battle until I can get it to stop or just lock my phones screen. It's becoming very annoying and I don't know what to do with it? I've taken the battery out and had a look to see if it was caught on the button or something but nothing. and that seemed to just mess my phone up and it's just had to reboot on safe mood. Any and all suggestions would be appreciated! Thank you!
