Hey everyone,
I have my optimus g for about 2-3 years, and I still like it!
But last saturday it showed a screen of death, running cm12.
The next day the phone was discharged, so I charged and tried to start it.
After some time it did start, but there was no boot animation / lockscreen.
What works:
-Phone boots normally (except for the black screen).
-Bluetooth: still connects to my car.
-Sound: the alarm still goes off every day.
-All buttons: Vol+/-, Power, back, home, settings.
-Notification LED.
What doesn't work:
-The display always stays black
-WLAN seems to be turned off. The phone doesn't show up in my wlan router.
-ADB via USB does not show the device.
What can be the cause for this? I already replaced the display.
What options do I have to access the phone again?
All keys are working again now.
Cleaned up the op a bit.

first i thought it was launcher pro's fault, but after changing launcher and rom release i'm pretty sure it's something else i haven't tracked down yet.
just after a reboot phone works as usual: screen lock runs after 30 seconds or by clicking the power button
after a while (days or even hours sometimes), the screen lock does not kick-in anymore: the screen just turns off and when you press the power button the phone is already unlocked.
i noticed that when the phone is in this "lock-bug" mode the notification led constantly shows a faint red light (you can barely notice it in the dark because it's really faint).
tested with:
launcher pro
go launcher
factory rom 2.21
blurless 2.34
I used to have the faint red light on after flashing a new rom.
It disapeared after I changed display setting to not automatic brightness.
It seems that the faint red light is the light sensor.
But I know nothing about your screen lock problem.
I have run into the same thing. I have not yet noticed the light, but I've had the screen lock stop working on my phone twice (I bought 3 phones 5 days ago for work). Like you, a simple reboot fixed the problem. I also tried toggling screen lock in the settings, and setting up a lock code, to see if the screen lock would start up. Both of my times, the first I noticed the issue was when I received a phone call and didn't have to swipe to answer, but that could have just been coincidence.
It isn't really a big deal for me or the employees, but it is a nuisance.
Happened to me as well, twice. First time it was just annoying that I had to reboot, second time it drained the s**t out of my battery in three hours.
So it's a bug allright.

same here.. it just stops working.. any fixes yet?
Apologies if this has been addressed before, but I searched and couldn't find something exactly like this...
Randomly one of 3 screen issues seems to be occuring on a daily basis:
1) Auto-Rotate stops working. Cannot get screen to rotate without reset (Yes, I've made sure auto-rotate is on in settings)
2) Screen will not Auto-Off. Even if I change settings to 15 secs, screen will not turn itself off. I have to manually turn it off. And, if I receive a text or any kind of notification it will light up again and stay on indefinitely.
3) Screen will not turn back on when trying to wake up device. Hitting the home button and power button both have no effect. Although the LED is usually blinking, and it seems the phone is still on.
For all 3 of the above issues, manually pulling out the battery and reseting the phone that way seems to always work. But, this is an annoying process to have to go through on a daily basis.
Also, I've noticed that these 3 symptoms don't occur simultaneously. For example, yesterday it wouldn't auto-off, but rotation would still work.
Not running any custom ROMs either
Hello,
Yesterday when I was done working and got my phone from my locker, I opened an app and immediately
the screen went black and appearantly the phone had switched itself off. I turned it back on wondering why
it did this, but as soon as it had started up and the home screen appeared, it turned itself right back off.
I tried turning it back on about 7 or 8 times until the battery ran out and I could not try anymore.
When I got home I put it on the charger and fortunately the phone stayed on, however the top of the screen
seemed to be 'trembling' a bit and some pixels were changing from light red to dark red to light red etc. (my home screen is red)
I decided to leave it charging overnight and when I woke up, the trembling had disappeared. I took it off the
charger and after scrolling through my Facebook news feed, found that battery percentage was decreasing quite
quickly considering it's on power saver mode. I thought it might be that the screen brightness is too high, so I went
to settings and tried to adjust the screen brightness, however it is not responding? My screen brightness stays
exactly the same no matter whether I increase or decrease it, and when I was doing that the phone switched itself
off again. I put it back on charge now and turned it back on, but I am quite annoyed about this issue because I
do not know what it is and my phone is only 5 months old. I hope any of you can shed some light on the situation.
Summary of the issues:
- Phone switching itself off
- Screen trembled yesterday
- Battery decreasing quickly
- Brightness setting not working
Info about the phone:
- HTC One X 5 months old
- Android 4.2.2
- No adjustments made to the phone with rooting or any of that
Thanks!
Must be a hardware failure if you havent changed anything software-wise
Is it overheating?
Is it under warranty?
And other sensors are working? But like TTG TriCkSh0tZz said , use your warranty if you can.

Ok, this is VERY irritating!!! I set my phone on my wireless charger before going to bed last night, woke up this morning and my phone screen has turned to Greyscale. Battery is at 100%.
1st things 1st - My phone is not in Power Saving Mode, nor is it in Ultra Power Saving Mode. Also...... I have already gone to Settings-->Accessibility-->Direct Access-->Greyscale (off).
I have tried toggling all of the above settings (I also have never ever used any power saving/greyscale mode to begin with). I have even tried switching themes, even reverting back to the default original theme that came with the S6. Nothing seems to work.
If I power off or reboot my phone, the boot screen is in color as well as my phone briefly is in color again while android is initiating the phone. After about 40 seconds, the phone turns to Greyscale again.
Has anyone else experienced this or have any other suggestions for me to try?
I am using a stock T-Mobile unrooted phone.
Ok, fixed! There is another "Greyscale" option under Accessibility for Vision, I turned Greyscale off. puzzled as to how that got switched on by itself but at least I know now.
Yes! The accessibility worked for me as well. I had to go to settings-->vision--> color adjustment. Then I had to drag colors in order from like this blue to brown to pink to purple. Thank you for suggesting vision! I was so irritated of the grayscale screen!!! I am guessing that it probably did that due to me ALWAYS going in and out of ultra battery saving mode (just my hypothesis--I might be wrong).
so this has been my backup phone for a couple years. my main phone just died so now im using this. I did the system update to 10. And from what ive read, ambient display no longer works. The screensaver only works when phone is charging. I tried the Always On app, and while it did give me a clock on screen while phone screen is off, it just sat in the middle of the screen, even though it was set to jump, then slide. the time never moved and i dont want that, it will burn the screen.
So is there a way to get the screensaver to work when screen is off? instead of only when its plugged in. I dont want to have to pick up or turn the phone on just to see the time.
Custom rom only, but your battery will take a hit.
