XDA-Dev:
I hope this finds you in high spirits and good health. Just a day ago my phone started acting peculiar regarding the lighting of the touchscreen.
Firmware: 1.6 // Build: DRC83 // Rooted: No
Damage: Slightly scratched hard plastic from dropping 2-3 times. Otherwise, outwardly pristine
Upon purchasing the phone, I immediately noticed that the screen would creak if it was pressed on the bottom right hand side (by the send button). The right side of the screen also protrudes slightly higher than the left when in the open position. I have owned the device for about 7-8 months now and have noticed that on the rear, when in open position, there is a scratch where the sliding mechanism moves. The paint is stripped and the underlying metal is displayed in those areas. And now on to the issue at hand:
When the phone is closed (touchscreen only):
- When pressing MENU, or any key that would normally illuminate the screen, this does not happen. The screen stays dim, yet the lights on the buttons bellow it brighten.
- If I slide out the keyboard while the screen is supposed to be on (meaning the buttons are lit up), nothing happens.
When the phone is open (keyboard presented):
- And the screen is off, if I press MENU, the screen comes right up with no brightness issues.
- At this point, if I close the keyboard, the backlight disables itself. The screen is NOT completely blank. If I reflect the light of the room off of it, I can just barely make out that it is indeed displaying whatever task it was that was open, but if I were in a dark room, there would be no chance of recognising what is being presented.
- Continuing from above, once the screen's backlight is disabled and I reopen the keyboard, it does not turn back on. I must turn off the screen and turn it back on for the backlight to resume normal functioning.
One would think that if the issue lies in a loose wire that once the keyboard is extended that the backlight would regain normal functioning. Because this is not happening and that it is only working under certain circumstances, I cannot accurately ascertain whether this is a software or hardware problem.
Attempted remedies:
- Soft reset (both rebooting the phone by powering off and on and by going into the reset menu)
- Hard reset (by going into the reset menu and hitting ALT+W, etc)
Neither of these attempts succeeded in restoring functionality of the backlight. I've also search high and low through the settings, but see nothing other than 'Brightness' under 'Sound & Display.'
It may be noteworthy that I have the paid application 'Power Manager' installed. Though, perhaps not since this issue was still occurring AFTER the factory reset when no foreign applications were installed.
If you require any additional details, feel free to give a reply with any questions. I'm sincerely hoping I don't have to deal with T-Mobile or HTC to have this repaired. Any tips, ideas or possible solutions would be greatly appreciated!
Regards,
Ian
Update on issue:
On the way home from work, as the battery was on it's last leg (less than 10%), I turned off the screen while the device was in the open position after finishing a text. Upon attempting to re-activate the screen, it would not do so. As always, the side buttons lit up, but the screen was blank no matter what I did. I could hear the vibration from receiving texts and the red 'omg I\'m dying LED' was still flashing, so the device had not died.
Returning home, I gave it a reboot by removing and replacing the battery. I've kept it in the open position since it has been plugged in and am quite afraid of manipulating the slide mechanism any further.
I'll be calling t-mobile to get their opinion on any further troubleshooting momentarily and report back.
Sorry for opening an older thread. do you remember what t-mobile said was the problem? i am having the same issue.

The ribbon wire in the slide mechanism is either broken or pulled out of socket.
Anyone else seem to have a problem with the ambient light/proximity sensor on their N6? I've noticed that a lot of times when i make calls, the screen won't shut off when i put the phone to my head... often with that resulting in my cheek touching something, and the person on the other end not being able to hear me. If i leave the phone at an angle against my ear so my cheek doesn't touch the screen, eventually the screen will shut off, but won't come on when i take the phone away from my ear, resulting in me having to press the power button to turn the screen back on.
Had that happen to me yesterday ... Rebooted and it hasn't happened today.

I'm having a issue now. Phone call comes in and screen stays on. I did a reboot, factory reset even installed custom ROM. It was working the other day. Anyway to calibrate this thing? Or do we have a bad sensor.
Also now my phone won't rotate screen.

Do any of you happen to have a screen protector on? As there have been some users that have been reporting issues with certain screen protectors. I believe most are tempered glass protectors that are the cause of the problems.
I took mine off and still nothing.

Did you try going to settings , accessibility , power button ends call, toggle that on and off.
We own two new Nexus 6 devices that are rooted and decrypted. We have the same issue where the phone screen stays on during a call. Rebooting fixes for a short period (hours or so) but the problem comes back. Other threads show this to be an issue with other phones (nexus 5) with Lollipop. Not sure of a fix. These devices are only a few weeks old so it is not a dust issue.
Having the same issue that just suddenly started. Rebooting does not seem to help.
Happening here too. Frustrating.
My screen turns off when taking the phone to the ear but it doesn't turn on again after i take it away from my ear.
It's pretty bad on my phone. The screen turns on when I am on a call making the notification bar drop down. Also, the phone doesn't wake up when I pull the phone away from my fasce 80% of the time. When I am on a call the phone randomly vibrates like I am getting a notification and when I look I have nothing. With all of this going on, making phone calls on this device is a nightmare.
Restore clean wipe did nothing.

The below mentioned fix is for brand new Nexus 6.

After completing the above mentioned step. Reboot your phone and try making a call. I hope the issue get resolved.
I tried this step on an unrooted phone, which was recieved just yesterday.
I got this fix from some other thread.

What app
Orzly works fine... It doesn't cover the sensor. The Slimwrap orange vinyl (leather) face was a problem for me, had to enlarge the cutout to get suitable performance. I believe the sensor is longer than it is wide, the opposite of the factory cutout? It frames the face of the phone nicely with this screen protector on and I didn't want to take it off. The 24mm added height changes the profile of the phone alot, it no longer rests on the speaker bars/guards. This must also have effected placing the wrap on as well. The larger cutout box for the sesnor is a detractor, but the sensor works 100%. This is good , as it is my intention to run nekid with this phone but its size precludes using a case with any of the pockets I currently own.

Thanks I was just having a crazy time trying to install the front, similar case (glass protector in front) and ended up cutting a hole for the proximity sensor about 2 times the factory height, everything (seems) normal now. I used this program to help make the minimum cut, and align correctly. Did you run into any issues with the thin left & right vertical part of the front cover? Mine seems to "wrap" around the glass protector, not sure if it will stay there though
Anyone noticed something similar?
Sometimes when unlocking phone with the unlock button or by double tapping it wakes up but is unresponsive to touch, the brightness alters with random intervals, wallpaper flickers. The phone becomes usable again after a few locks and unlocks with the button , although very rarely but still sometimes it automatically locks itself after unlocking.
Factory reset didn't help and before that I was using all the latest updates.
Is this a problem on the hardware side?

Pretty sure mine is. It started with similar issues and has only gotten worse. Flexing the phone a bit makes the screen go all wonky and it's the only way I can get it to come on/become responsive. I will more than likely have to send it in to Sony. Ugh.

Idk wth all that means. Some of it I can guess at...but for a phone that was treated rather gingerly...to have behaved in such a manner after X amount of months (7, I think it was, before stuff started going wonky) w/out the screen being cracked or damaged in any way...the answer is lost on me! Hopefully it doesn't happen again.

I have some problem with touchsreen. All work fine until I put my device in pocket (or press him). After I take out my device I can't unlock him, and me need turn off screen and turn on him several times, until touchsreen stabilized.
Who have simmilar problem with touchscreen?
same here :/
same here. I can click few times right after I turn on the screen but only for one second.
same here... tried reflashing etc. via *#7353# -> dot mode, I can see that a spot is being "pressed" in the middle of the display and 1,5cm down from the top. And constantly, thus another touch is not possible. Usually after locking the phone and turning the display on again it works for some time. But even in the recovery it doenst work... sometimes... under key test. Randomly the touchscreen is being pressed.
Had no problems until now... always had a screen protector foil on, but even with a new one and without one it doenst work. Did not dropped my phone, neither I have screen cracks etc...
Any suggestions?
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.

Yeah that sucks, i can imagine..... i too hate the idea of refurbished units being swapped for warranty....bs, should be brand new unit!

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

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.
