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

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

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?

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?

. . . and I have to hit the power button to turn the screen back on. To be more precise, the screen turns itself off when I hold the phone towards my ear during calls, and it does not turn itself back on when I hold it away from my ear.
This is obviously some power saving feature that doesn't work as well as it should, like a gimpy proximity sensor. Anyone know a workaround for this ?

Well, ther is a proximity sensor there, near the camera on the top of the phone, on the screen side, and this screen-off thing is more like feature to save power and not to anoy you during the night when you talk to the phone
Don't know why it does that, maybe your sensor is faulty, but try to flash a different ROM and see if something changes, also make sure you don't keep your hand or finger near that sensor, just to be sure, i personally use this ROM and i don't expierience this issue.
Hope this helps

If it is possible on Galaxy S2, then it is possible on any android phone , and it is, but there should be made a tool for that or a flashable zip, i'm not that experienced to tell you exactly what needs to be changed, but it can be done, that i know
Same problem here.
Changing roms didn't solve anything
Anybody have solution for this ?
If you have a screen protector covering it then it might be wise to make a cut out or take the protector off altogether.
Sent from my Nexus 4 using xda app-developers app
as i remeber , you can write something in the build.prop that will disable proxy sensor
Im having problem that is almost same. After a long call(when screen is turned off) it turns off but screen or softkeys dont reply any way.
I have to turn of the screen with power button and let it be around 10-15 seconds and turn it on. Then lockscreen appears and everything
works. This is really annoying because I cant cut the line any way.
Not using screen protector and tried couple of custom roms. Allways have the same issue.

Problem is identified with proximity sensor itself, on App " Android sensor box " if you select proximity sensor it reads always 0.0cm no mater what you do with phone.
It seems like HW failure, will have to look at it in more detail.

The problem is when you try to make a second call display turns off, phone is working you can talk, but you can't end the call or nothing because screen is off, so you have to turn it on or wake it by pressing power button.And it's happening only on every second call, so I make a first call, as soon as I try to make a second display turns off, and only power button wakes it, after that you can make the next call normaly, but problem repeats on second call.
Phone was stock on ICS 4.0.3, and making problems there. So it's now fully unlocked ( S-off ) Hboot is 1.28. I have tryed many custom roms, but the problem repeats
I think it's the hardware problem with proximity sensor.

I think too. Sounds like your proximity sensor is weird.

To continue the story, I removed the MB and when the proximity sensor is out of the case, it works ok. When I put it back in case( behind screen ) it doesn't respond again.
Cleaning didn't help, will have to find another one to make sure what is the problem.
I have fixed my problem thanks to this thread

Hey guys so I'm having the following problem, during a call when I put the phone near my ear and the screen turns off, sometimes the phone stucks, what I mean is the after I remove the phone from my ear the screen remains turned Off and the buttons do not respond.. But the call is still working.. I had gueste rom then I changed to cyanogen but the problem is still there...
Unresponsive phone perhaps, because as far as I know, nothing of the sort happened to me ever.
Also, does the screen light up when you end the call...let's say by using power button?
Not likely, but I'll mention anyway, check if anything is blocking the proximity censor - holding habit, cellphone case etc.
Similar issue,any way to disable the proximity senzor?

I have pretty much the same problem,the screen remain turned off after i remove the phone from my ear and i can't activate the screen or press any buttons until the other person terminates the call.
I run a proximity test from the Hidden Menu and the sensor detects as NEAR all the time even though nothing is in front of it.
I reinstalled several roms and i still encounter the same issue therefore it must be a hardware problem.
I would like to specify that i don't use a screen protector therefore the senor is not blocked in any way.
Is there any way to disable the proximity sensor completely?is there a application or a setting for that?

I have had the same problem, with many roms. I think if you are on some of the ICS roms, you will have to expect some bugs, like this. I am now on Temaseks build 135.1 with his kernel and I dont have any of these bugs. It seems ICS for our P990 is to be expected soon, so try a ROM as close to stock as possible and wait for our ingenious developers to get the last drivers working and you will see a lot of bugs disappearing. I would not recommend you to disable additional hard/software.
One app that has helped me though, with some of the ICS issues, is AnTuTu CPUMaster. A free app in Play and it allows you to set your minimum clockspeed a little higher than standard, I set mine around 400Mhz and it took care of many of the little bugs related to phone not reacting according to expectations.
Good Luck
Have the same problem and man... its a huge pain...
I am on the official CM7 latest release. I used to be on temasek's one and did not encounter the problem. As I can;t change ROMs these days, any quick fix, calibration app that would do the trick? Thanks!
I have recently purchased this phone via swappa and haven't had any issues prior to this and that has been three weeks (other than a light leak).
The issue that is happening is the LCD will not turn on. When the phone is unlocked via knock on or power button you can move your finger over where the lock circle would be and feel the vibrations showing that it does register the touch. Then usually I would just hold the power button till it rebooted and this would sometimes fix the problem, on a side note the boot LG logo and boot animation do not show up during this time simply the lock screen would randomly appear.
That is problem, now on to what I tried to fix it. I have put on an entirely different rom and the problem persists, I have also flashed a different kernel on the stock rom with no avail. I at first thought it could be due to a faulty proximity sensor, but the last time the screen was on I checked it with sensor box. One way I have been able to reproduce the problem is after locking it putting it in my pocket and waiting around five minutes, this then will make it so the LCD does not turn on ( Which makes it seem like it has something to do with deep sleep). Also something I just found since I was actually able to find the power off button, the screen also won't turn on when the phone is off and plugged into the charger (this makes it seem like hardware issue). It seems like as long as I keep the phone from going to deep sleep the LCD will turn back on.
Some of this makes it seem like a software issue other things make it seem like a hardware issue. I just was wondering if anyone had any ideas or if I need to buy a new screen, if the mobo is bad, or if I could fix this with software. Any and all ideas are welcome.
Thank you all in advance.
This has has happened to me 3 times so far while I am plugged in charging overnight. I'll wake up to see that my screen is on. If I hit the power button it will shut off, and then come back on in a second or two. Even if I flip it upside down so the screen is down, I can still see that the screen is still coming on. The only way for me to fix it is to reboot the phone. Anyone else experiencing this?

I believe Safe Mode is still in Android. Try it. Warning: it will break your home screen widget layout.

The same reason it does in Windows. You use it to narrow down what is causing it. If Safe Mode cures the issue, you know for sure its an installed app. From there, process of elimination.
Right?
Just got the phone and have had this happen a few times also. No apps installed that I didn't have on my previous phone.
After a bit more testing I have more information. It seems like it only happens when it is plugged in and has reached a full charge. Once I unplug the phone from its charger, the screen stops coming on by itself. This is still some kind of bug, there's no reason I shouldn't be able to keep the screen off even if it is fully charged and plugged in.

Ive tried this for two nights and it doesnt seem like I've had this issue since using a different charger...
My problem turned out to be the button accidentally being pressed and the screen lock setting being set to "5 seconds" after hitting the button, as opposed to right away. So the screen was going off, it wasn't locking, and an errand touch of the side of the phone while moving it would make the screen come back on without seeing the lock screen again because it was within the 5 seconds that the setting enabled. I was not familiar with this setting being on my previous phone and the Turbo was set to this by default. Hope this helps.
I agree that it is a bug, however, I was wondering, is there a way to get rid of that screen entirely? Frankly all that screen does for me is waste the battery, so being able to not have it at all would be great.
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.
