Lately the display on my G3 will flicker and then go out. When it does the only way to turn it back on is to keep pushing the power button until it eventually turns on again. Sometimes it'll just take one or two presses of power button....other times it'll take more. The weird thing is when the screen is off the phone will still respond to what I'm touching on the screen even though it's blank and not showing anything. It's hard to describe without seeing what it does...and it's not a constant problem. Anyone else experience this issue??
