Hello everyone,
I'm a newbie at rooting.
I have used CM for 3 months but for a week it got a little strange.
Scenario 1) When I push the power button to get to lock screen, the soft buttons' light turn on for a moment but no change happens on screen. I push power button again, the same result. No other respone from my mobile. If I push power button for 10 sec to reset, i see a little green or purple light beam from the bottom right. After a while, it disappears. And still no response. I remove the battery as a last resort and put it back, when I push the power button, it's the same. Little colorful light beams...
Scenario 2) A short time ago, while I was playing a game on it, the screen just turned off and I pushed the power button... as you guess, the story goes on the same way.
It's now off, I couldn't get to it in any way.
What can I do to solve and how?
You guess it's urgent.
Sorry for my poor English, thanks in advance.
Can you restart the phone in download mode, or recovery mode?
I just figured out something:
The phone turned on and I disabled developer settings. After this, when the screen is locked and off and I push the power button, I see nothing on the screen (maybe a little purple or green beam at the right bottom) but the soft buttons turn on. I slide right to unlock without seeing anything, I pass the lock screen and it's now open. (when I touch the screen, the soft buttons turn on again and again as it should be) I just scroll the main pages right and left, push the volume or main button, they work. (it beeps when the sound is max) after 30 - 40 seconds... yay! The screen is on! It's totally the same all the time. It needs time to turn on?
Is it a software problem or is my screen about to break down?
Thanks again!!
it's a software problem. You can either factory reset, run the trim command if you're running android 4.3, or change to a different ROM.

Last night my phone was working fine. This morning I awoke late for my day because my alarm clock didn't go off, looked at my phone to figure out why and all I saw was a blank screen. Playing with the power button I am able to get it to a mode where the orange charging light turns on and the softkeys seem to respond (they provide haptic feedback at least). The backlight stays off, but I can tilt the phone around and see a cyan line stretching the width of the screen and I can manuever it up and and down using the volume keys. There are 10 items in this menu it seems since on the 11th click of the volume button the line jumps to the top of the page.
Can anyone help me? I've tried taking out the battery for 10+sec, I've tried removing supplemental hardware (sd/sim cards), I've tried on and off charger.
EDIT: It would seem the key is to loose all hope of it working, but continue to press the power button in desperation and after about 40+ attempts at power at this point it might turn on. I'm officially terrified I am going to wake up without my phone at any given day now =[
Rooted? Stock? Recovery? Rom?
Guys i was in my settings a few minutes ago and i came across a feature which enabled me to open up my notifications by just tapping the screen so i enabled it and went to the homescreen to test it! Upon tapping the screen the phone started maing a beeping noise and a blue line started scrolling continously downward on the screen! I cant turn the phone off ! I only seem to be able to reboot it which doesnt help! I needto power the phone off i assume and then maybe do a hard reset??? Advice needed please
anyone?
What setting did you access I don't believe anybody will be able to help if we don't know where you went and what you changed. The things you mention are very vague and don't really paint a picture of what is happening.
Also if you want to turn the phone off without using the on screen settings just hold onto the power button for about 10 seconds it should turn off, after that hold power, home button, and volume up to go into recovery to reset or what ever it is you please.
Also is it showing you an X and Y axis? If so then you just go into settings, developer settings, show screen updates and turn that off the grid should go away. I am not sure what your issue is but that seems like the most likely option.
I picked up my v10 (LG H901 unlocked) and tried unlocking, the screen was completely dimmed out. I could hear notification sounds and had the haptic feedback when unlocking with fingerprint but nothing could be seen. I took out the battery restarted the phone and the screen booted up into the home screen but dimmed out completely again after barely 3 secs. It's continued till now, I hear notification sounds, the vibrations work but the screen is completely blacked out.
Taking out the battery and reinserting starts the phone normally but goes blacked out again after it loads.
I'm on Android 7.0. Help pls

Power off the phone...hold down the volume down and power buttons at the same time....when you see the lg screen appear briefly (1 second) release the power button while keeping the vol down pressed..then re-press the power button....all this in the end should boot you into recovery...it will ask you a couple of scary questions which you can say yes or no to....the bottom line is this...if you can see fine in recovery then you've set the brightness way to low and/or installed an app that's done that to you in your ROM. If recovery is to dark to read then it's a physical issue with your device. About the only thing that's gonna undo the rom issue if it's that is a factory reset (which you can do from recovery). If you were using auto brightness then make sure when you get back into your rom that you disable it until you can figure out what you did that caused it to get so dark you can't read it.

Thanks for the response.
I have the same problem. Did you find any solution?
It all started 2 days ago, when watching a clash of clans replay the screen turned off for the energy saving thing. I pressed the power button to bring it back, but the screen didn't turn on, i could hear the game sounds, and the touch screen was working, after the replay ended i was able to tab the buildings in my village and hear the sound they make. I pressed some random combination of buttons, i think its power+volume down and the screen turned on. It happened a second time during that day, and i was able to turn the screen on again. But the day after that trick didn't work and the tablet was stuck with a black screen.
I tried a factory reset, but the menu for it wouldn't appear, the odin menu by the other hand worked fine. The recovery menu should appear when with the tablet turned off you press volume up + home + power in that sequence, and releasing the power button at the samsung logo screen. But the menu never appeared, so i navigated it blindly and i think i managed to reset it, at the next accension i was prompted with the personal information field, name, google account, time settings etc..
The phone started again, with all default settings, and all my files where gone (so im assuming the factory reset worked) but when the screen turns off it doesn't come back by pressing the power button, it comes after trying a few combinations (and again i think it is power + volume down and wait a few seconds).
So im worried it was all in vain, also the screen brightness is bugged, and changes the colors, the become reddish with low brightness and some colors disappear.
Edit: After i let the screen turn off for the third time today, it doesn't come back on. So im back at the black screen...
I have never used any modifications of software. Only used stock firmware.
My coffee was spilled a little on device. Cleaned it immediately.
Then I got a freeze after boot up. I could see the home screen, but touch screen not responding, "Menu" and "Return" lights continuously lit and not responding. The removal of battery or long press of ON/OFF button was the only method to turn off. But the battery % shown on screen was correct each time. If I called the device, it was offline.
I connected the phone to my computer and it was recognized by windows. I did not transfer any files to phone by odin, but I have Odin application.
I used 3 button combinations to wipe cache, then boot up, but no change.
Then I used 3 button combinations again to return to factory settings and wiping everything. Now I get a solid screen where I need to select language but the menu and return lights a on continuously, and the touch screen does not respond.
So far, I can see that my three hardware buttons, on/off, volume, home buttons are working. Phone also was returned to factory defaults. But the problems continue to be the same. They are: no touch screen reaction, continuously lit menu and return buttons, home (OK) switch not working after boot up.
I have started to think that there might be a hardware problem. I have downloaded the service manual, can solder things, even have a microscope if needed.
Can somebody guide me to check where is the problem please?
