I am currently experiencing a problem where if I turn on the phone or leave it idle for a bit of time the screen will turn all black except for the bar on top. Things I did to the Moto Q9h tonight was, take the ringtone limiter registry out and installed candlelight. Also, the youtube flash file. Hopefully someone can help me fix this!!!
I did the master reset in the settings not the "Z+E+POWER ON". This left everything intact including candlelight and everything else. Candlelight was the cause of the problem. Wonder what was wrong... Would've liked to have kept the program.
