Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance
Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]
Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you
actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something
Hi. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.
I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.
i used the app both light senor and proximity sensor are working fine
any other tips that i can try

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!
Tip: use a led flashlight to see what's on the display
Ps. Stock m7

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.
Is the display not broken?

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?
When I bought the watch back in November, the screen would stay ON all the time. I know it to be a fact because I used to leave it on a desk without ever touching it (for hours) and it would always display the time (it was like having a desk clock, for when I would rather not wear it to have more comfortable wrists while writing or that sort of things).
Also in the train (I used to travel a lot in that period) I would leave the watch hung on the wall while sleeping (at night) and it would not turn itself off, so I could check the time in case I woke up in the middle of the night, without neededing to reach for the watch.
Recently (it was January) I noticed that it does not work like that anymore. After a very short time, the watch screen goes off. It is still in standby: it goes back on if I touch it or press the button.....but I want it to stay on 'without limits' (in dimmed mode). It was like that before.
Somehow this is the behaviour of the 'keep screen always ON' setting.....but in fact, that setting is already set to 'ON'.
So is there some kind of firmware update that changed this behaviour? I would like the clock to not go off when it is not on my wrist, sometimes I just need to keep track of time AND have my wrists free....and it is not possible anymore.
nothing?
It is actually a key feature....no point in having a watch that doesn't show the time unless you touch it (if you leave it on a desk or simply hung on a wall at night). Also I wonder why it changed (did not do this last year so I thought it must be some update but could not find anything in the changelogs about this).
You have the Setting enabled in Android Wear for keeping the screen Always On?
My screen only goes out when on the charger. When I had a Samsung Gear Live, it would stay on while on the charger, via the Developer Setting on the watch to keep the screen on while charging. But that has never worked for me on the "R", not even last year.
The screen of the watch goes off while charging (although I remember it being different back in October...).
The settting for 'screen always on' is activated. I activated from the watch, from the phone, restarted the watch, nothing worked. The screen goes off after a while IF I DO NOT wear the watch.
No problem if I wear it....that means there is some connection between the screen going off and the accelerometer :-/
But as I said, I need the watch to stay on even if I am not wearing it (working at a desk or similar when I can't wear the watch, I would look at the time at the watch lying on the table). I am sure 1000% it did not turn off before (started in January, or at least I noticed it in January). I read all the changelogs for all the updates and I did not find anything about this.
Can someone also try? My brother has the same watch and his also goes off if he does not wear it. I find this really unneeded. At least they should have put a setting available.
You best option is Wear Charging Widget. It will keep the screen on when charging. Although it does dim a bit, like a night clock in a mostly dark room. It is the only option I've found that works.
I wanted the "R" to work like my old Gear Live and keep the screen on when charging and even when not wearing it. But I've never found a means for that to happen short of Wear Charging Widget.

Yes it looks it is like that now. Maybe you bought the watch after the two last updates (501 / 502) ?
Would be nice if somebody else, besides me, could confirm that in fact the watch was staying on (dimmed mode) all the time even without wearing it in the previous months (release date to December).

I've had my "R" since last year, before v5 came out for the watches. And the "R" never kept the screen on while charging. I never noticed it involved simply not wearing it. Since when I'm not wearing, I'm charging.

Screen shuts off completely
The screen on my GWR has started shutting off, completely dark not dim. I checked the settings and it is set to "Always on screen": ON.
This is a fairly new problem, it did not used to behave this way, I could see the screen dim, and move my wrist and it would go bright and display "OK Google".
Any ideas on how to fix this bug? Or do I/we need to wait for a software update/fix? Current software version: 5.0.2
Watch is not very useful if I can't see the time without having to push the crown/button.
Anyone else having this issue?
Screen is working again.
Had some time to try some options, did a "Reset Device" and the screen came back.
Lost all the apps I had loaded on the watch, not a big deal, wasn't using many of them.
Guess I can just download them again from the play store, if I want them back. Something I loaded onto the watch may have caused the loss of the screen.
Last couple of apps I downloaded were CompassX and a charging app that shows charging progress while charging.
Glad to have the watch face back.
I'm having the same problem as you. The ambient mode won't come on. Instead of dimming to ambient mode it now just goes dark completely (like when it is charging). I would love another fix before I have to reset the watch. Any ideas?

Bumping this. I reset the watch. Went about two weeks and now back to the same problem. Ambient mode has disappeared. It's just black all the time until i turn it back on.

I confirm that I have this trouble also in normal use, previously it worked fine and would stay on all the time if that's what I wanted.
Am very tempted to reset the watch after backing up.
I have nearly the same problem. For months now, when my screen dims, it goes to a very dark/dim red. I've removed all programs from my phone and did a factory reset on the watch three times. I'm not sure what else to try. Is there a way to flash the memory? It seems like a setting is stuck in the non-volatile memory.
I was having the same problem and found that I had theater mode set on. Switched to off and now works great.

I'm experiencing the same. On my watch it seems to be somehow related to accelometer. Almost everytime, when using LG G Watch R in golfing, it starts to shut down the screen. It doesn't wakeup even when tapping the screen.
I haven't found other solution than resetting the device
Same issue with 5.1.1
I had this issue with 5.0.2 and hoped that the next update would solve it but sadly it persists in 5.1.1 .
Theatre mode is off, Always on is on but still the screen blanks, showing the ambient mode screen briefly before blanking.
I've reset multiple times, occasionally Always On comes back but only for a short while.
Always on is a feature I really like
Fixed it on mine
I had to turn wrist gestures on. With it off screen on doesn't work.
I have the exact problem on my GWAR, software version 5.1.1. I bought my in December and it never happened until now. It started happening yesterday all of a sudden. I tried factory reseting it through bootloader, throught settings, uninstalling the Wear app, uninstalling the watchface i was using, and still nothing.
Here is what I did to fix it (and i know its overkill): Uninstall Wear app, clear google play services data and reset the device through settings. Now it's finaly working.
Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?
I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).
This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.
I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.
same has happened to me

Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.
I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.
I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.
I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.
It's supposed to be water resistant, but I've never dunked it intentionally under water. Bought this in 2017. Unfortunately, I had an accident and it fell inside a sink full of hot water (while I was taking care of a patient) and it stayed there for a minute or two.
What happened are the following:
Power button no longer works - It was a little wonky as it kept turning the screen on and popping up the camera. I tried to turn it off, but it kept turning back on.
Stock camera app - doesn't work anymore. whenever I try to activate the app, it just crashes.
Rear camera hardware - focusing is gone. Using another app (camera zoom fx) I can access it, but pics are blurry. It can't focus on images 12 feet away.
Front cam hardware - there was a mist that fogged the camera. but it seems to be working fine after.
Screen - the screen was relatively ok after the dunking. However, water got inside the S-pen port. I immediately removed it and started drying the phone for 48 hours. I tried to return the s-pen after, but it seemed to trigger something and the screen started flickering. it lasted for a day but it's now completely normal.
Aside from those, everything is fine with the phone. I managed an online backup to Samsung account and everything.
If you're still here, here are some of my questions. I appreciate all your help.
1. I've now turned it off for a complete drying. Now I can't turn it on. Is there a way to turn it on? Is a USB C jig available to do this?
2. I left some sensitive data in the phone *coughbootypicscough*, is there a way to access the memory and wipe it? or maybe factory reset the phone without turning it on?
3. Can the cameras be replaced / fixed?
Hoping for all our help.

The fact that water was hot made it easier to gain access to the inside of the phone and personally I'm going to say it's now a hardware issue and the phone is likely no good anymore.. If you're worried about certain pictures on the phone just destroy the phone so no one could possibly take parts out of it and try to use them. Smash it with a hammer, drive over it, you get the idea.. Just get another phone at this point the reason I know it's a hardware issue is because of what your camera did so the water made it past the seals mainly because it was hot and loosened the glue to get past it.

it actually still works. I tried hard not to turn it off because the power button is broken. Last night, I fell asleep and forgot to charge it and battery drained and phone turned off.
It still charges but I can't turn it on because the power button is broken.
I was hoping if anyone knows if a USBC jig can help and turn it on for a bit or any other way to trigger download mode and then restart.
Try to hold Volume down + Bixby button and plug the cable in, it may be goes in download mode amd than you can reboot you phone. If not try only with Volume down and cable.

I'll try that again. For now, I'm placing the phone inside a box with desiccant to ensure that it dries completely. Hopefully, it restores some function to the powerbutton.

Try opening and removing the simcard tray while the phone rest in the box with desiccant. Hopefully can remove water vapors better and faster.
