Has happened twice in the last month.... I pick up my phone and press the home button - screen doesn't come on. Then I press the sleep/wake button, same thing. Takes about 3 or 4 presses before the screen finally comes on. Anyone see this before?
I had a similar incident where I pressed the home button and the display didn't light up to reveal the lock screen, but I had forgotten that my phone was off at the time.......Seriously, though, I've never experienced anything like what you've mentioned. Sorry.
