Help please, what are these horizontal black lines?

They only just appeared today, randomly when I took my phone out of my pocket. I've restarted the phone to no avail, and am panicking because I dont know where to begin..can anyone diagnose my problem?

Looks like dead pixels, but the image isn't really clear enough.
Take a screenshot with some app.
If you see that in the screenshot, then reflash your firmware & ROM or flash an RUU.
If you don't see it in the screenshot, then it's a hardware problem.

Thanks, I took a screenshot and it's not a part of it. The lines keep getting bigger and bigger!

Sounds like it needs to go for repair. Is it under warente? Best of luck to you!

I too have this issue. It was present from the moment I powered the unit on. I continued with the setup to see if I could adjust the screen or maybe an update might fix it. But sadly no dice. I'm calling Google tonight to see if they can send me another unit or repair this one.

Had the same problem earlier, when i dropped the phone accidentally.
Observation: It gets darker and grows when the phone heats up, and lighter (almost cyan blue) when the phone cools down for a significant period of time with the screen off.
i had to keep the phone near an air conditioner vent for a few hours with the phone turned off for it to disappear.
once the lines disappear completely they dont return back, unless if you drop them again (which is what i did a few days back again.. and the stupid lines are back )
If you have any other ways in which you can get it resolved pls share with us.
Cheers,
Alan

Nexus 5 screen died today + dangerously hot lower screen

Went to unlock my phone this morning off the charger and the screen is totally dead. Couldn't unlock or do anything to it or even see what was going on, called Google and ordered a replacement ASAP.
Went through the not fun task of doing a nandroid backup without seeing what was on the screen and doing some trickery with screenshots then backing up my entire SD card.
However, here's the strange and potentially dangerous thing that I noticed later when I got home this evening. I went to look at the phone and go to a fastboot flash with the factory images and went to touch the bottom of the screen. When I went to do so, to the little bit of the left of the LED light was a SUPER hot portion of the phone. I almost burnt my finger it was so hot.
Not sure what to do about the issue, I feel like if I just call the support line they won't actually take in my concern legitimately. Any suggestions?

thats something quite strange
let us know what google says about RMA and this issue

Agree, maybe it's just your phone, maybe it's all the batch. Which batch/model do you have?

On my Transformer Infinity, sometimes the screen won't turn on at all. On a few occasions, if I press Power enough times, I get a glimpse of a message saying the Launcher process has stopped, but then my touchscreen doesn't register any input. The tablet is also sometimes running quite hot at those times. The only way I know to recover from this is press the Power button long enough to force a reboot, then everything is normal. Could this be what's happening? Do you know if the phone is still running under the black screen? Have you tried forcing a reboot, and did it work?
As for the hot phone, I've noticed my N5 does get a bit warm when I'm using it intensively (4G, WiFi, Bluetooth, GPS and screen on all at the same time and in use) but not enough to burn me. Could be hard to tell which component is heating up like that since I think it could be the screen backlight, SoC or battery... Do let us know if you find out more.

I had called them and reported the screen totally dead with lines streaking vertically and got a new replacement ordered. It wasn't until late last night when I got back and had the screen on in this dead mode that the bottom was extremely hot. I'll have to call them back and let them know

Yeah hopefully, it definitely seems like it could be one of those things that could potentially start fire.The one I have is the LG-D820. Any more info I can provide?

Yeah, no its definitely dead. There were streaked lines across it, rebooted it multiple times. I ended up going into the bootloader and recovery via adb/fastboot and all that jazz. It eventually just would not work now.
In regards to the hot part I definitely think it was the lower part of the screen. It was quite literally half an inch away from the LED to the left. Was super super hot then once I shut the defective screen off (I could tell by the backlit light or whatever) it wasn't hot anymore after a minute or so.

Is it black/white? 16 or 32? When did you get it?

32gb black version. I ordered it immediately when they announced it that day.

mine gets really warm when i'm doing a TWRP backup then it goes into bootloop after and wont cool down. i have to force it to power off from recovery and let it cool, but i've always seen it happen. i wonder if yours was attempting to boot over and over for hours and cooked itself.....? i have a launch day black 32gb too, running Cataclysm with Franco at the moment but it was doing it on rooted stock with stock kernel

I had to send my 19 day old 32Gb Red Nexus 5 in to LG for the same reason. I was using the phone and all of the sudden had vertical lines and the bottom of the screen got burn your fingers hot. Waiting to see what LG does with my phone. The only thin I can figure is the synaptics chip which controls the screen is bad. Its the only thing in that area that could get that hot. I also noticed when I first got my phone the glass in the same area looked like it had a slight wave in it. Didn't think anything of it at the time. I'll let you know how it goes.

Is RMA/replacement applicable for Rooted and unlocked devices?

I don't believe its an issue with developer phones as long as the issue wasn't caused by something you did like brick it by flashing a wrong radio or something like that. It has to be a manufacture defect to get it fixed for free.

My device issue is related to power button. there is no software issue.
The power button is rattling since from the purchase of the device.
Hope my device gets repaired.

Like I said. Hardware issues that are production faults should be covered.

Nexus 5 Black Screen, But Still Working

So my Nexus 5 (a couple months ago) has started to just randomly go black. I get notifications and stuff, and the backlight but no display. Not sure what to do or what part to replace. Would flashing/rooting help at all?

Appears to be a hardware problem.
Was the phone every dropped or exposed to water/moisture? Possible loose connection inside?
No way to tell for sure if the phone needs a new screen unless you are able to test the motherboard in another N5.

It's been dropped a couple times but not like any major drops or anything. Im pretty sure I checked all the connections inside and they were good. Im starting to figure out that the phone has to be off for a little bit then I have to charge it and turn it on and it works again

Sounds like it could be a damaged lcd or lcd connection. If it can work after being charged while powered off, could be battery or USB flex cable issue.

Ya I figured out I have to reboot it a bunch of times then it will work

I think it might be the battery because this is my dad's old phone so it's been in use for a solid 3 years.. I wish I knew for sure though

So I have discovered that if my screen is on for a while the task bar at the bottom starts to shift up and down

Have you found out more about this? I think I have the same problem. My phone never turns black while I use it. But when the screen is off/sleeping, it sometimes won't turn on again. So a force reboot fixes it. Sometimes this happens a lot, some times it works fine a whole day.

I could also mention that this happen every time I unlocked the lockscreen on stock ROMs, and custom. But nameless ROM for some reason got it to this point at least. If any one have black screen on unlocking the block screen, try nameless rom...

Maybe, I don't think so. My phone was useless, black screen on every screen unlock. But namelessrom took that away, so that tip about nameless was for those who have the same black screen I had earlier. But now I have the same black screens as you do. Anyway, if you want to try it out, nameless-rom.org

Happens with my nexus too. The screen goes blank randomly ..... But i have managed to deal with it.

Its happan to me also, with 4 nexus 5 of my family.
Is a firmware problem?

I'm trying to buy a new flex cable to see if it will help I'll update when I find out

You're replacing the USB charging flex cable? If you are, be careful with cheap third-party replacements as I have read reports of people having issues with charging, signal, or speaker functionality after installing the cable.

Ya so i sent it to LG finally and the diagnostic said that it was a flex cable issue which I was sure that it was anyway but I have a confirmation now

I've had a similar problem when my display suddenly started failing. First, there was colourful bands over the working display, then colourful static only and then black with backlight only. Bought a new phone, left it for a year and today after digging in the phone for a while I found a fix. The connection between the motherboard (the top bit) and the daughter board (the bit below battery with USB and connection to display) was somewhat loose and when pressed on, the display worked beautifully. I stuffed the insides with some tape to maintain pressure on the connection and phone works great.
Might not work for your problem, but it's worth a try if you're out of warranty and have tools to disassemble the phone.

Black Screen Of Death

Hi All
Has anyone had any issues with a black screen?
Everything else works like incoming calls and notifications but the screen it totally black!
Woke up early hours last night and noticed no AOD so tried to turn my phone on but the screen was just dead. Tried the volume and power button but still no joy

Power it down completely then plug in the charger.
If nothing shows on the screen it sounds like you lost some significant hardware... maybe just a connector.

Same happened to my SM-N9860 unit when I woke up today. I about to unlock and the display suddenly went black screen. Did everything but no luck. I am also sure it's the display that's f***d up. The phone is still working - I can still access it in Dex and Link to Windows. This is my second Samsung phone with f**d up display for unknown reason. This is crap Samsung. Not expecting for this from an expensive flagship smartphone. I swear this is the last.

By the way, how did you fix your phone?
I tried searching it on the net, seems a number of Note 20 ultra units are experiencing the same.

Seems that display replacement is the only fix.

Poor parts QC.
Samsung will substitute components and smaller chipsets in the middle of a production run. This can lead to unpredictable behavior especially after firmware updates... or outright failures like this.
Not reassuring especially with a flagship phone.

hi im facing exact same thing in my N986 B Galaxy Note 20 Ultra. I had 10 percent battery left. i had put phone on charge and saw after 20 minutes and tghe screen was black.
Now its blackscreen can connect with tv via hdmi dex mode
but phone restarts after 10 minutes.
the touch seems fine as mouse function works phone is on but no display
can you tell exactly what you did when your phone revieved after one day
did u keep it on. charge all tiime tried reset or removed charging
or nothing and tried after 1 day
Edit After 24 hours of tapping slappingrebooting installing stock firmware. my display came back alive.
last thing was i was using phone in dex mode and trying to open close camera app rapidly by direct touch on screen. i dont know what worked but it saved my 300 dollars of screen replacement

I have exactly the same issue.
I was typing on whatsapp when suddenly screen get black. It was on friday morning. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
One day earlier I had an issue with the new magisk update. I freeze magisk manager wich was force closing but later, I managed to reinstall with dex and was working fine. Not sure if it's related.
I already flashed fresh stock Android R rom, wich I thought would solve any issues related to magisk or any other software issue.
24h after flash stock rom and keep force rebooting and taping, and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking, is it normal? I took off S-pen and microsd tray to see if it was the cause, but the noise still persists). No damage, water, or anything else. Only 2 months of use.
Display is still dead.
I'm draining battery now with some apps that also vibrate phone, to see what happens when full drained.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Any tips are welcome.
Thanks in advance.
Hope I have that lucky as well.

It happened to me again today. Surprisingly, a strong knock at center of the screen revived it again.

Not good if there's a recall... crap QC is getting to be a bad Samsung habit.

Those of you with BSOD issues: Did you have intermittent wifi connectivity issues as well? My N20U had the 'connected to wifi AP but no internet' for the last month. Then today after unplugging the OEM charger, checking charge level, never picking the phone up from the desk, and returning to it 30 minutes later the BSOD had hit. No amount of hard restarts or waiting fixed it and it had to get shipped back. Just wondering if there is any correlation between the wifi issue and the screen going out, and if people should start sending their note in ASAP if the wifi problem occurs before the screen goes?

hello
i had the same problem (didn't have any Wifi issues before)
and after the screen went black for 2 day , it came back and worked for a few hours.. then went off again and Never came back
i tried everything, resets , cables , connecting to Dex or Hdmi , updating.. but Never worked
i went to Samsung and they said screen must be replaced ( will pay for it as i am out of warranty)
can you tell me what have you done or if anything worked for you?

My screen went black after a screen replacement. Only the front glass was broken not the digitizer or actual screen. From what I can tell it's not just the screen that's dead, it's the digitizer too. The S-Pen board underneath it all isn't even registering. When I plug it in the computer doesn't see it so Dex won't connect and there is no signal for HDMI to work. Had the USB port replaced just to be sure it wasn't a bad port.
It's like some one took the graphics card out of a computer and took the touch screen monitor. The phone still gets signal. It connected to my smart Fossil watch and I could answer calls and texts.
But the phone is 9 months old. And from what I've heard from parts distributors it's not the screen that's the issue. So now I have a new motherboard. Now I have to figure out how to program it....

Were tou opening and closing the camera while mirroring screen? or on blind?
It seems in your case, the display went back to normal as strange as it turned off.
Could you please share the mentioned youtube video?

Sorry for the late reply mate. The Scenario when display got back alive was.
1. My phone was connected via HDMI to TV in Mirror mode (Not Dex Mode). I also had mouse and a keypad connected since i am using Samsung Dex pad which came with my old note 9
I have from day 1have doubts about the stock camera app on my Note 20 Ultra. The app misbehaved from ranging to camera fail, and force closes on Android 10. That why i did below next
2. I forced close camera app , cleared its data and then while watching on Tv
i placed my finger on Camera icon and repeated opened it and closed it with back key.
since the display on phone was off so i used Tv for help
BUT physically doing the action on phone with fingers not with mouse on screen via mirroring
3. while i was repeatedly opening and closing app by touching the display with finger suddenly i saw camera app asking me for location tags pop up on display and from that time onward there has been no issue and the display is working as nothing wrong happened.
I wish and hope you have resolved issue by now. Please do share your experience for others . since when i had this issue, i found very less information about it. but i saw around 15 to 20 users having such issues especially with Note 20.
Conclusion what i have understood is either its some issue with Note 20 Ultras Camera Firmware or THe Electjet 45W Charger the culprit which i bought for my Tab S7 and was using to also charge my Note 20 Ultra. I have stopped using this charger for my phone and tab and since that day only using 25W OEM charger which came with the phone. I have now this 45w Electjet charger connected via Samsung dexpad which caps its charging speed to 15W.
Here is the link of the video. and i tried all things mentioned and then after exact 24 hours
the display came alive back when doing activities i mentioned above. and i have no link with the guy or channel who posted this video. I was just trying everything to bring life to my dead display .
PS: i had only 5 percent belief in this video . i dont know what worked
i had prepared my mind for the300$ plus panel display replacement.
i just read two recent more comments which state they got their phone working back.
Do read the comments posted as there might be some more clarity of things to try.

Worked! Slapping it around and massaging it with reboot. Who knew Smack My ***** up! - The Prodigy was referring to modern phone fix'n.

I'm here literally in tears, my keyboard wet typing this because the video actual "Fixed" my phone. I don't know if its a long term fix or just temporary but after 24hrs of a black screen its good to have back a working $1400 phone.
So if this happened to you, dont be skeptical and just try the steps. Last resort is to bring it to a technician or Samsung but definitely try this before.

Fingers crossed it goes strong for the next two years.

Mine went dark about 2 days ago. Been trying the above solution with no success.
But can I ask did you guys hear a slight rattle?

No luck as of yet. Been sat for a couple of hours while watching a film trying the foxes above. No luck.

It just came back on this morning. All I did was let the battery fully drain.
