I was annoyed at the lack of proximity sensor so my "face" hits buttons on the screen. I was also annoyed that pressing the "end" hardbutton does NOT end the call just goes to the main desktop screen. Grrr
hehe
SO I found a quirk that gets around this (but has a nasty side effect)
as soon as I am on the phone with someone I hit the power button to turn off the screen and continue the call as normal no screen on no accidental button presses.
NOW when I hit the "end" button it does not goto desktop it just turns the screen back on and I can press the "end call" onscreen button.
it then puts me at the "lock screen"
I turn it off
and here is the side effect. a second later no error no warning poof white HTC boot screen. phone crashed and is now restarting.
I can repeat this as many times as I want so its consistent.
I am going to try it again but without the "power off" at the lock screen at end of call and see what happens IE see if there is a way to NOT cause it to crash.
More later
