Avoid screen turning on when ending a call
I've been searching around for an answer, but have come up empty to this puzzle :-)
I mostly use BlueTooth devices during calls on my HTC One (and One S before that), and it really annoys me that the screen turns on, unlocked, when ending a call from the BlueTooth device. Most of the time the phone is in my pocket, so it's rumbling around in there changing settings, calling random contacts and so on.
How do I stop the screen from turning on when ending a call from a BlueTooth device?
Thanks a lot.
