I use the Power button on Razr Maxx to end my calls quickly. This is a vital funcionality for my needs. Therefore I'd like to be able to use Volume up/down buttons to wake up the screen during a lengthy call, instead of the Power button (which also would end the call). Pressing Volume button to wake up was how my original Droid used to do it, but I so far I wasn't able to find a similar setting on Razr Maxx. Any advice? If it's not possible to use Volume button to wake up, what else can I do? I need to be able to wake up the phone during the call without hanging up on people.
