[DipakDhawani]

I am having a problem with the display of z ultra. The problem is that the display do not gets off, even after pressing the power key.

What I am trying to say is after pressing the lock key the screen is still on (Blank) it does not gets off. Like we are viewing a full black wallpaper in fullscreen. I do not exprience this problem when the OPTIMISED BACLIGHT option is ticked. But when is option is not on, the display do not turns off. And even when is option is on, after pressing the lock key the display gets blank for 2 seconds and then it turns off. But when is optin is not on after pressing the lock key the screen remains black and blank.

I not facing any problem while unlocking the phone. it unlockes in first time.

Please help me in this.

Hi, I am having same problem. What u need to do is on the Optimized Blacklight and restart your device. Then only u off the optimized blacklight and use as normal. I am on 532 firmware.
If you not on that option and u restart device, u will have longer boot up times. And backlight keep on, brightness control not working.
