I sometimes get unresponsive buttons, but most of the time they are quite sensitive and work as intended. This would lead me to believe any issue would be software related or a system resource issue at the time of unresponsiveness.
I do however have another question....Is there a way to turn of the backlight on the buttons? If i'm watching a move or video on my phone in the dark the last thing I want to bright glowing buttons. This is really quite annoying. I have tried a back light app which did not work and holding the power button and waiting for the buttons to blink and letting go when they are off, which is pretty much impossible to time. So anyone know of a simplet way to Dim or turn of the back light to the buttons?
