[Q] Keyboard backlight problem - Android Q&A, Help & Troubleshooting

Hi:
I bought a Zopo Zp990+ last week.
Today, I have found a problem with keyboard backlight, it's always on, when the screen is on, when the phone is in repose mode and when the phone is shut down!!. Only the light is off when I unplugged the battery. I have just restored the mobile to official firm and it's the same.
I have calibrated the proximity sensor yesterday, Is possible that I have calibrated it wrong?
Could you help me?

Any idea????

Display blinking when the unit is turned off??

I've had this unit for a few months. Here is the issue: the display blinks with backlighting LED on when the unit is completely turned off.
This drains the battery faster than when it's just asleep. I currently have the new official Tmobile ICS unrooted on it, but even when it was rooted or with stock version, this issue was still there.
Anybody else noticed the same thing? do I have a lemon?
Thanks

Not heard of this before. I'm guessing the backlights on the three silver menu buttons at the bottom of the screen don't light up either.
As a first step I'd just charge the battery for approx 12 hours/over night as after any storage the phone probably needs a good charge.
Given you have had the phone operational now for a while and probably a few charges, has the back-lighting now restored it's self??

This might be a hardware problem, so I can suggest that you go to where you bought it from and tell them the problem

[Q] Nubia Z7 Mini, Strange behavior of backlight

Hi,
Suddenly this week my phone's screen start blinking/flashing. It looks like the light sensor was drifting.
A day later, my phone's screen turned black. After a long charge, i could start it.
But i saw that my screens backlight never turn off. After locking the screen, the backlight goes off for a second or 2.
After a short period the backlight turns on again (but no text, only light). Cause of that my phone's battery is draining like hell. 10% in 30 min or so ( not using).
There's a second strange behavior , my phone is rebooting several times a day (approx. 10 times in a hour). But he reboot only when in lock mode.
I made a video about the backlight, i hope this makes it more understandable.

As a solution, i tried a few things:
- Taken the battery out
- Hard reset
- Reflashed original rom
- Reflashed Nubia 5.0 version.
But the behavior of my phone is still the same.
Any idea's?

S10 Lite Black Screen, Switching On but no splash screen

Hi All,
Today morning my S10 lite started going display off automatically and I tried to hard restart by Power+Vl.Down it shown splash screen and restarted.. then again same issue of display off. then again I tried hard restartd for couple of times its switching on, vibrating when on but no display at all. Do I need to wait until the battery is drained and charge it and check? or display is gone? or any other methods to check? thanks in advance.

Hard to say. Could also be a battery issue. Best to let it be checked in a mobile device service center/repair shop.
