[Q] Screen stays on whild phone off and charging - Sprint LG Optimus G

Im having a problem on my recently rooted/unlocked/updated to 4.1.2 Op G.
The screen stays on continuously while phone is off and plugged in. I checked developer options and screen options and time outs are all set to 30 seconds.
Anyone else having this problem? Is there a fix anywhere?
I also find that the charging animation comes on if i hit the power button while the phone is off and charging but eventually it goes away and the screen stays on.
Also if the phone/screen are both off and then I plug in the phone the screen comes on and stays on.....
help?

I have this too. When I turn the phone off and charge it you can see the screen is barely lit. I noticed it when I unlocked, so assume that is the cause of it

Miners done this for as long as I can remember, but it doesn't seem to cause any sort of problems, so I've always just ignored it

saw this as recently as last night. I just waited until the battery was charged a little and turned it on to make sure everything was fine. Weirded me out though lol.

Screen blacks out while charging.

Anyone else have this issue? I couldn't find anything on it. As long as I'm charging, my screen constantly turns black. Only locking, then unlocking will turn the screen back on, but it usually just goes black again.
This only happens while charging. Stock Froyo, but happened just as common with 2.1.
Any insight is appreciated.

it sounds like it is just timing out like when you have it unplugged correct?
if you want to make it so your screen stays on while charging go to settings>applications>development> check stay awake
If i am totally off on what you are asking can you be more specific about the problem.
Thank you. I do have it set to stay awake. The screen turns black, but actions can be taken (just can't see what actions). So if I hit the lock button and hit it again, it will turn back on for a split second and then go black again. It is very strange.

i have the same problem and it has nothing to do with the timing on the phone, it turns off but u can still hear the "click" when u touch the phone, supposedly a few phones have had the same problem and is a problem with the connection that the chargin port is deffective or something like that, the best thing you can do is return the phone to where you purchased it from and tell them you have a defective unit, there is nothin you can do about it

GNex will not turn on

Phone was plugged into the computer charging and my twitter notification tone rang. As I unlocked the phone and opened twitter, the screen froze and 5 seconds later shut off. Now after pulling the battery and letting the phone sit, it still will not turn on!!! Any ideas?
Phone was rooted with superboot, and google wallet was flashed on December 5th... I am completely out of ideas!
What happens when you plug it into the wall charger? Do you get the charging batter icon on the screen? Will it power if plugged into the AC?
No power either way... It seems its completely dead. Could it be possible the battery is doa? Find it hard to believe it could be anything else.
Power should work even if the battery doesn't

Try and call the phone. It could be a rogue app.. I installed wave launcher and it did something similar yesterday. The screen would turn on the immediately off and wouldn't turn on again. I called the phone and it turned on, then went to uninstall the app while on the call.

Odd Automatically Turned Off

went to hit the power button to use my phone and nothing happened... not sure if it was froze or if the power button stopped working... i held it down and nothing... was sitting at a black screen...
had to pull the battery to get it working again... has anyone had this happen? is the phone actually on and the power button stopped responding or did it shut down and the power button stopped responding?
4.0.2 unlocked... not rommed... adw launcher
I had that happen once. I went to pick it up and turn it on, and it was just dead. like it just powered off by itself.

It's called the Black Screen of Death. Usually happens when a custom kernel doesn't play nice with your phone.
I was on stock 4.0.2. No root.

Yeah it's happened to me anywhere from 3-5 times these past few weeks. Either that or it will just reboot itself randomly. I'm not complaining though... it's nowhere near as bad as my Nexus S was. Lol

this happened to me twice today for the first time ever, am on a custom rom but havent updated in a few weeks... Im seriously thinking its Chrome for android...as thats the only thing i changed recently (google voice updated too). and i seriously havnet used my phone lately other than using Chrome.
It happenned to me once since I've had my nexus. Don't even think about why
Happened to me today, screen was blank but the LED notification was blinking. Asked my fren to call me and it was ringing meaning the phone was still on. Had to remove the battery and put it back in and then it was fine.
Mine turned off on its own last night, it was when I plugged in my charger while it was turned off at the mains.. very strange.
are any of you on 4.0.4?
hopefully not
I haven't seen any shut downs or random reboots on 4.0.4 yet. It's been less than a week though, so we'll see.

The only time my phone has ever shut off with the power taking 5 or so seconds to work has been because of a music app Slacker.
It shuts my phone down randomly. I think it is not fully compatible with ICS.

[Q] Screen not fully turning off

Hey folks, I've noticed an issue with my One V (CDMA/PrimoC). Sometimes when I press the power button to turn the screen off, it doesn't fully shut off. In very low light, I can see that there's still a faint glow behind the screen. It doesn't happen often (that I can tell) but I have had some crazy battery drain randomly and this might explain it. My phone is bootloader unlocked, rooted and this issue has occurred on various ROMs (I noted it at least on the stock rom and on shubhamchamaria's nON-sENsE rom v1.1 which I'm currently using).
Has anyone else noticed this happening? If you have, do you know of a fix?
Probally the backlight leakage issue, which means you will have to make it all stock again and send it back to HTC. This is a known hardware problem.

When I turn my phone off, the screen seems to also stay on but it is hardly noticible and turns itself off later

I'm not sure if mine eventually turns itself off but it definitely doesn't turn off at 1 minute like it should normally.

S III sgh-i747 turned off and wont turn on URGENT

i apologize if this has been solved but i am on a very tight time frame as i need this phone for work and cant spend any longer searching. my phone randomly turned off by itself this morning and will not turn back on. it gets to the samsung splash screen and the screen just goes black and the phone wont do anything, its like the screen is stuck off, i have to take the battery out to make it turn do anything at all again. it was stock this morning, never been rooted or anything, i just rooted it about an hour ago and installed twrp and flashed jedi invasion 5 on it in hopes it would help. now it gets past the splash screen and to the initial setup screen but it only stays on it for about 3 seconds before the screen goes black again and i have to take the battery out for it to do anything again. im not an expert by any means but i have flashed note 2's and played with them a bit and know my way arround them for the most part. any help would be EXTREMELY appreciated.
almost forgot to mention, in download mode it says qualcomm secureboot: enable
not sure if that means anything but i didnt get any errors while flashing or anything
thanks everyone

I would make sure you have to correct drivers installed for the phone on your computer and ODIN back to stock. You can give that a try and see if it helps.
I'll check that out when I get home but I'm pretty sure everything is right, it was doing it before I even flashed anything so I think something else is the problem

Faulty battery or power button. You can try ODIN back to stock, not likely it will help.
It's not a battery or power button problem. Before I rooted it if I took the battery out and turned it on again it would turn on fine if I kept the screen from turning off. and the battery was staying charged, and if it wer a power button problem why would it work to turn the phone on but not again after its on?

My vote is a faulty power button. Has been known to happen on the S3. Could be power issues though. Bad battery could be the culprit. If flashing stock does not work see if you can get a battery to test out.

ok so i flashed stock and it fixed it temporarily. after i flashed it it was working great so i decided to root it and flash jedi. so i did this and it still worked great. (at this point i should mention that the sim card in the phone has been deactivated this whole time) so since its working i activate the simcard, restart the phone, and the problem started again. so i took the sim card right out and turned it back on and it works perfectly fine without the sim card in... what do you guys figure? should i try a new sim card? has anyone ever herd of this happening before?
EDIT: tried my other sim card in it and it doesn't work either, so it snot the simcard itself
Bump
