My OSD has recently began an annoying habit whereby, while the usb cable is plugged in for charging, the screen will intermittently turn on and off.
It is not a faulty USB cable since the same thing happens with several USB cables.
I'm sure this can't be good for the screen.
The only thing I can link this to, is that I recently installed the Words with friends app. I've not yet tried removing it but first wanted to see if anyone else had experienced this problem or what the resolution is.
