I'm getting very sick of having to jump through hoops to use my keypad during calls. whenever I need to enter details via the kaypad during a call I remove my phone from my ear, display pop's up for a second, then disappears again, I then have press the home button to make my display come on again, which it then most of the time goes off again.... so I try again, I keep pressing, rotating, placing phone to ear, and removing it again until I finally get the screen to stay on and I can use the keypad.
What is causing the screen to go off? is this a bug? it's very very very annoying..
