Sometimes when I press the power button to bring up the lock screen, the entire screen has this extremely bright neon pink tint. Everything is still visible (text, icons, etc), but the color is messed up. Sometimes it's bright blue, and sometimes it's green. It goes back to normal colors when I lock the screen and bring it up again. It happened quite a few times now but not frequent. Does anyone know why this happens?
Mine's unrooted
Also, how come none of my physical buttons (volume or power button) takes a picture? The volume buttons adjust the zoom and the power button activates a lock? I thought there was suppose to be a button so taking pictures will be easier? =\
Thanks in advance

There are some custom ROMs that allows you to press the power button to take a picture. Stock doesn't have that feature.

does the color thing only happen when you unlock your phone........then it goes away. or does it stay that color until you lock and unlock again.

Looks like u r on stock. If u bought it from an AT&T store, and within 30 days, get it exchanged for a new one. If over 30 days, return it to AT&T warranty store and they'll give u a refurb one. Atleast will save u the botheration of going through all these efforts.
If u didn't buy from any store and got it off outside of any medium where u can return it, then stick to trying out suggestions posted here to set it right.
Hello guys... i save my phone from a brick, and then i tried to switch from BR firmware to french firmware (in order to upgrade to JB) using RDS, but when the rebooting process start, the phone stayed in black, it didn not power up... so, it does not start up yet, when i push power button, the green led turns on for a few seconds and then the phone get off... i can not enter into recovery mode either... just the green led shows up and so...
i hope someone can help me fixing this huge issue.
best regards!!!
Hi All.
I have a problem with bootloop on my MTCD_KD. I want to clear user data but i don't know how to enter recovery mode.
I try to long press power + RST but no luck.
Please help me.
It can be a pain in the butt.
The Joyings changed from the easy power+rst on MTCB to this goofy process on MTCD:
Pres and hold power for a LONG TIME
Eventually it will go black, and reset and a bit later the front panel lights will flash THREE TIMES
Let go of the power button after the flashes
Wait one second
Just quickly click the power button
That 3 flash - 1 sec - click is what seems to activate recovery mode. If you miss the timing just right it will just continue to boot up normal.

Hold power button down until it starts to reboot and the lights flash, immediately release then press and release the power button again one time and it should boot into recovery mode

Hi zmylna.
Try long press power until button lights blink, and then short press power button again. That's right for my JY.

On my MTCD the button marked power wasn't the power button.
The real power button was the little reset hole that you press with a paperclip.

Good luck, on mine it took a few tries to get it.
I ended up just randomly pushing the button until it went to recovery.

For my unit (KD), i long press RESET (like yo do in the video).
After several secs. the lights start blinking (three times i think) and after that it makes a long light blink.
remove pressing the button in the starting of that long blink, and press button again once quickly.
I have KD Android 5.1 Quad core, MTCD, 1024*600 car unit.
unfortunately just after changing of my car battery, the unit completely dead no screen, no power, no sound and it is not turned on at all.
I checked that all fuses are connect.
when I am holding Power button more than 10 second, only the button lights, turned on and by releasing the power button the LEDs turned off again.
The company say probably because of main board problem and suggest me finding someone to check the main board if it have any problem or not?
would you please help me how I can check the main board?
Is it possible that the core board have also problem?

It seems the device is bricked and do not turn on at all. I connected audio/video out (normally provided in back of unit for connecting optional rear monitor) to a another monitor but I don't also see anything. By pressing and releasing the reset key is blinked one time and the unit don't turn on.

Even bricked you can see at least the lollipop logo....the video input is managed by mcu (not Android) and it should work even Android part not booting...so...or it is a mcu problem or a display problem.....did you checked what I said before (wait the time for a normal boot and try if touching the screen the headunit does anything (Even you couldn't see anything)

thank you very much for your helping. I don't see the lilipop logo! the back camera video input also didn't work. I also connect the USB flash memory (the flash have LED) but the Led of flash memeory don't turning on. I can not check the radio because the headunit is now disconnect the car and I don't have any connected speaker to unit.
A few minute after connecting the power I am feeling the back of headunit is warmed a little.
hi, i just have bought this device nxt-l29 huawei mate 8 64GB edition and i have that problem that the device's volume goes down on its own i use the slider of the volume to lower the volume a little and it just stays there, any time i raise it and make/receive a call it goes back to the lower level. i tried to reset, made the software update nothing helped the only thing that help is that i turn off the phone then again on and the issue is gone for some hours and it just starts again after a while.
sorry for the bad language.
Hi, i just bought a Poco X3 NFC 128Gb, after 3 hours of use, you know, initial config, app downloading, sing in, etc. I put the phone into my pocket and five minutes later when i tried to unlock it, the phone was death, not responding to anything, i tried to connect charger but nothing happened, not even a led turns on o react, i forced reboot but the only feedback i get was one long vibration followed by one short and nothing else, that every time i tried, i tried all combination of buttons, including keeping one key pressed and repeatedly press power but nothing, i tried to connect it to my PC but it was not detected, i'm advanced user so i have all the drivers, all the tools, not working with community tools i tried, not working with mi flash, not working with mi desktop suite, not working with adb or fastboot or even recognized.
after pressing and pressing buttons i tried holding the volumen - key plus pressing power key and releasing it in spaces of 5 seconds, after 3 o 5 tries it got a big vibration and the power led started to bright, my PC reproduced the device connected sound but it doesn't appear, not adb, not fastboot, not mi flash, anything, it react to certain touches to the screen and the wrong finger vibration when i use the wrong finger in the power button/ Fingerprint reader but nothing else, not sounds, not reactions no any other buttons, or anything to think it was a dead screen only, i tried everything over and over again and no more progress so i give up and send it to warranty with the hope no *tupid excuse by the seller, I'm waiting for an answer so, can any of you give me one please, what happened.
Before i forget, the screen never showed anything again, no logo, no fastboot, no recovery, no backlit even, just black screen of death. Help Please!
Sorry for any mistake in writing, I haven't use English in an exceedingly long time.
Mate, even if the factory has done its QA, some dud devices still make it out into the wild.
Looks like you got one. Hope the seller gets you a new phone fast...
