the call alert does need to be fix, but in terms of waking the screen, idk what there is to do. if you make it so all you have to do is touch the screen, then every time the screen touches something in you pocket, like your leg, the screen would turn on, not unlocked, but on. and it would kill the battery. if they made it so you only need to press the top button. i could see many scenarios where that button could be pressed by accident, turning your phone on.
