[Q] Nexus 5 screen showing colorful static - Nexus 5 Q&A, Help & Troubleshooting

Has anyone come across this before? I was watching a video on MX Player not too long ago, and it seems to have resulted in a permanent colourful static for the phone.
I can't really tell if it's doing anything, but when I go through the motions of resetting it or booting into bootloader, the screen does not change at all.
Interestingly the volume buttons are still working, and if I press the area of the screen where I think the buttons are (e.g., the back/home/programs buttons) I get the right vibrations. Which leads me to believe my screen is broken, and that it's a hardware fault. I'm hoping pretty hard this isn't the case, as my phone is only two months old and it was a replacement for a 6 month old Nexus 4 which had stopped charging.
Anyone come across this before? I'm hoping there's a kind of solution somewhere out there... To make matters worse I bought this phone via a parallel importer AND I'm currently overseas and won't be back till the end of January.
Sigh. Photo of screen is as attached - please forgive the terrible quality as I had to use my laptop webcam.
Thanks in advance, everyone!

Only time I've seen something like this was when my integrated graphics card on my desktop overheated, everything still worked, but colorful static everywhere. I'd let it cool down for a while, chances are it was pretty hot when it did that, and see if high temps might make it happen again.

I just had the same thing happen. Phone had been in my pocket and I had just taken it out to check the time maybe 10 minutes before it happened. The only difference with mine was I bumped into a table and hit the phone in my pocket. It does have a case on it and there is no sign of damage at all such as a cracked screen or anything. The static only lasts for a few seconds and thats right after I force it to reboot. After that it just goes to an all black screen. My LED indicator light is still flashing at me telling me I have an email though so I'm not sure what the deal is.

Were you able to resolve this issue? I too just experienced this issue as well and my phone is currently unusable. Thanks!

Do a full wipe as in wiping the entire phone and making it as if you just got it out of the box. if it persist RMA

Hi, I broke my screen (really bad smash) and had have this static on my new screen. The new screen was apparently fully tested. When using the slim port i can display on my TV and the digitizer works fine, its just this same colour static on the handset. I am now waiting for a replacement USB flex (it was a bit bent in the break) and i expect the new USB flex will fix it. If not then its a bad screen.
Will post the results when i get the parts

Fixed!
Hi,
My new USB flex arrived today. I installed it and found my screen is working perfectly.
The first pic is the same colour static that the op had.. Second one is the USB flex board / ribbon. Ebay for 20 Euro. Please remember that USA users are LG D820 and Europe/rest of works LG D821. I think its important for this part as the aerials connect here ans they are different in USA.
Good luck everyone

Static screen and freezing
Hi All,
Need help here with my 6 month old Nexus 5. It has been pretty good with no issues but since last evening, it started behaving weird. The chronological events are as follows
1. While browsing on Chrome some websites were not scrolling intermittently. This was only in the browser.
2. After about 10 mins of the above behavior the entire phone froze and didn't release itself. I had to force reboot by holding the power button down for about 10 secs. When the screen came on, it was the static screen
3. I again pressed the power button a couple of times but no use. Held it again for 10 secs, then phone rebooted and everything was fine.
4. Continued to use the phone and everything was normal until this afternoon, when the phone again froze while browsing a website
5. Since then the phone screen shows the static and if I press the power button once, the screen switches off and press again the screen comes on with the display showing properly. I can now only perform one touch which is registered and the screen freezes. If I switch off and on again the next screen / action is shown which is the action I did in the previous touch. Every time it registers one touch and I have to switch off and on again to see the next screen. Sometimes the phone just shows static and I have to wait a few seconds (30 sec) before using it again.
6. If I make a call to my phone, I hear one ring and then it is busy tone like I've cancelled the call. However the phone does not show the incoming call.
My phone has been intact and is well protected with screen guards and case. There is no physical misuse / abuse of the phone. I managed to shut down the phone and enter recovery. Here as well it only registered one touch, though the phone was processing and moving the next step. I somehow managed to initiate a factory reset through the settings, but no use.
Now in about 2-3 hrs the phone has become completely useless. I'm uncertain what the problem is, all my touch inputs are registered and processed. The screen just doesn't refresh to the next and requires a power off/on. I picked up this phone in the US and now in India. So I can't RMA the phone and I don't have warranty for this in India.
Any suggestion will be greatly appreciated.

I'm getting the same issue. Tried soft and hard reset. Opened her up and seated all cables. The issue is still persisting. Is replacing the USB flex the way to go?

Hey I have a nexus 5 32GB and the screen started to do weird things and now it isn't working at all. Its the same in recovery mode also do I think that it's not a software problem.
I think there is an issue with the motherboard. Please help me out.
Thanks in advance.

Same thing, Screen now black. Won't turn on...
Hey everyone, I know that this is kind of late to the thread, but I have what I believe is the same problem as everybody else here. I had my Nexus 5 in my pocket for maybe five minutes, and in between the times that I put it in my pocket and took it out again to reply to a text, the screen went all colorful and static on me (Red tint, almost as if I had twilight on, but I didn't). I tapped the back, and the colors went back to normal, but the digitizer wasn't responding to touch. Then, It went black. No color, the speakers weren't working, neither was the backlight on the display. I took it apart, and figured its either the USB flex cable (which looked frayed), or the mainboard. If its the USB flex cable, then I know I can repair it. If it's the mainboard... well, as a sixteen year-old who has no current source of income, I'm out of a $400 phone.
Pictures attatched. Thanks!

I took the phone the LG service center and the technician seemed to know this issue and immediately said that the USB flex cable needs to be changed. The entire fix took about 5 mins and the phone is working fine since then.
Sorry for the delayed response.

I hate to necro up this thread but I'm having similar problems to the op with my nexus 5. About two weeks ago I saw my screen get grainy just like the op and many others mentioned and then the screen went completely black. The screen still "turns on" but it's just black with the backlight on. I can hear notifications and other things and I'm hoping that all I need to replace is just the flex cable. If it's a problem with the logic board then I'm screwed basically.
Anyway that's my story. Bought the flex cable and it'll be here by tuesday so I'll find out then if I'm lucky or not. Fingers crossed.

Hey man, did you ever try this out and get it to work? I have the same problem and was thinking of trying this out but wanted confirmation first.
Thanks!

Just wanted to post here to say that this thread just saved me a lot of money!
Had the same issue (static showing on the screen). Local phone repair shop told me it needed a new screen, without even looking at it(!), and it would be £120 + labour. Told them I would think about it, and came home and did some more research, found this thread. Ordered a replacement USB flex cable from eBay, and fit it by following a YouTube tutorial, and now the phone is back working fine. brilliant!
Thanks xda!

I had a problem where my screen looked like an old CRT TV with particles flashing all over on anything with a static dark background. Any ideas

[Q] TF101 Screen won't turn on

Hi everyone, this is my first post here. Thanks in advance for any help that you folks can provide.
I've had the TF101 for about six months now, and it's been fine. I was using it yesterday on the train and all was good, but when I got home and took it out of my bag it didn't seem to start up. I thought it might have been a battery issue, so I let it charge overnight. Tried starting it up this morning and I got the same results. So I started looking in to other issues.
The tablet is definitely starting, adb will recognize it in its list of devices, and if I plug it in to my tv or desktop monitor w/ HDMI, I can see and interact w/ the Transformer UI (of course this is kind of painful since I have to do some guessing about where to put my fingers).
I had rooted it using rebound821's scripts and directions here, so tried an unroot to see if that was the problem. I ended up with the same results.
Does anyone here have any insights as to what the problem may be? I'm hoping to avoid sending it back to ASUS, so I'm fine w/ opening it up to look for loose cables.
So I thought that brightness might be the problem. Maybe it was set to 0 and I just wasn't seeing anything on my screen. Sadly, that doesn't seem to be the case.
I tried setting brightness at the path below to to 0, 50, 100.
/sys/devices/platform/pwm-backlight/backlight/pwm-backlight/brightness
Still no luck.
Has anyone encountered anything remotely similar to this (even if similar is just a dead screen)?
There have been others with dead screens reporting what you are, at least I have read a few reports, I think they just had to get them RMA'd, I don't recall anyone 'fixing' a dead screen, especially if you still have adb and touch working then the screen itself and backlight seem to have broken completely- some have reported the backlight dying and thinking the screen was broken, but it was just the backlight (I guess in bright light they could see pixels working, but couldn't make out what was on the screen without the backlight). I still think they had to get it repaired either by Asus or by someone who was capable of doing internal repairs with replacement parts..sorry for your luck
Looks like I'll have to send it back. I took it into the brightest light I could find and couldn't see anything at all. Guess it's the screen and maybe the backlight too. I'm pretty disappointed this happened, the only thing I can think of is that the bag I had it in was hanging from the chair in front of me on the train and it was swaying a little, and that shouldn't be enough to dislodge a connection. Either that or just some freak hardware failure. Still, I guess it's not that common of an occurrence. Thanks for the reply, I'll slink off and try to get in touch w/ Asus now.
I have experience same
My TF101 broke in the same way, screen blank. Conected to tv I`ve got image digital touch work. I shut down my TF101 normaly and screen never go back to live again. Tablet was in a protective bag (when I trave by car), just no reason for not working ( no problem at screen, previously, screen perfect - no dead pixels)
Did you guys get this resolved? I had the EXACT same thing happen yesterday. Was working just fine. Put it in its sleeve, into a protective case, into a briefcase, got home and dead.
HDMI works. I tried to call Asus but they say i'm out of warranty.
Thanks in advance.
Must be something wrong with the connections that it decays over time. I've had mine since October last year and its been fine except for today when I brought it home it wouldn't work.
I was able to fix it though. I held it vertically with the bottom edge down and tapped it firmly on my desk a couple of times. The screen came back on. There is a strong possibility that this will happen again and my tap fix won't work, but it's working at the moment

I had exactly the same problem discussed in this thread. I was also able to bring the screen of my TF101G to life by tapping it firmly on my desk with the bottom edge. It works for now. But it is certainly disconcerting to know that some connection in this rather expensive gadget are loose and all this can happen again. I guess I will not carry my transformer around any more - just leave it at home...

Same problem here had my unlocked bootloader tf101 for awhile now, one of the first ones out... had a great life gave it to my girl when i got the transformer prime and the screen just went out yesterday, still goes in apx mode and still recognized by computer, screen just straight up died, think it's too late for a manufacture warranty, maybe ill look but think it's gonna be no dice... sucks obviously something in the design to make this happen to so many of them...
My TF101 appears to have a dead screen. I am rooted and running Revolver Custom Rom. When connected to my pc, I am able to recognize my device. My screen will not turn on so I cannot use recovery to go back to stock. I am set up to use ADB, however, I am not very knowledgable with ADB. I am convinced I have a bad screen and I am still under warranty. Is there a way to return the TF101 back to stock using ADB? If anyone can point me in the right direction, I can probably figure it out. Otherwise, I may just try and replace my screen and see how that works out. Thanks for the help.
My backlight died on Tuesday. Similar situation of working in the morning, headed into work with it in my bag, no brutal knocks or anything but one jolt just must of finished it off after a year and 2 weeks abuse (yes 2 weeks out of warrenty).
Going to attempt to take it apart this afternoon and play with the ribbon cable as reseating it has solved quite a few peoples problems.
Woo! It worked! Very happy chappy.

Screen goes derp
I don't know if I have the same problem or not.
Backstory: I own a Transformer TF101 that I got for my birthday from my girlfriend. It was meant for travel and bs'ing around at home. Took it into work and quickly realized that I could use this for work. That went over so well that the rest of the office became intrigued. Once these came on sale on groupon, the office manager went all in on 10. These are all refurbished transformers with docks.
They have all been handed out and I now have a transformer for home and work. Kind of nice...but I do a lot of site observation so using my personal transformer was a risk that I had to take all on my own (survived a 5' fall off of a parapet wall already).
The problem: From the first 5 minutes that I had the thing, the transformer screen went blank. I opened up google play to download a few apps that I could use for work. Scrolling down I saw some choppyness which I considered the processor/memory having issues loading everything on the screen. Before I knew it - boom blank screen. Rebooted and the loading screen stays on for 2 seconds before the screen goes blank. I can tell it's working because it plays a sound at start up. I can also tell the screen is lit up (it's like it's showing a grey screen because it can't show true black colors). If I hit the power button again it goes completely black. I hit the power button again and the screen flashes to the lock screen and immediately goes blank again. I could do this over and over and over again.
Anybody having the same problem? It's refurbished....I'm guessing apparently I got the dud.
I ran into pretty much the same problem. One morning, the tablet screen would just not turn on. Sometimes, it came on and immediately shutdown, but it is still on the "On" mode. Hit the power button again will bring it to the off mode. Toggle it one more time, sometimes, will turn on the screen a off again. I was able to get it back to work with a factory restore. However, it has the following problems.
1) As soon as I adjust the brightness, the screen will go off again. And there is nothing I can do to bring it back except another factory restore.
2) The screen will flicker (and sometimes produces some clicking sound) when charging with the screen on.
Looks like my TF101 is having same issue, screen gone off suddenly (hdmi shows up in TV fine)...I am going give a try on reseating the cable hoping it resolves the issue.
leonpr, is there some tips/things I have to make sure before attempting this. I found a guide here and another youtube video on this issue as a reference...
Thanks..
Screen won't turn on unless factory reset "fix"
My girlfriend has an ASUS TF101. If the brightness goes up to 60%, the screen is blanked (no backlight either) and the only way to get it to turn back on again is to hard reset. This coincidentally happened at the same time as an update from ASUS. After lots of Googling it does not appear to be related. I was hoping it was and installed several custom ROMS which all experienced the same issue.
As a temporary work around, until I get the guts & the money to be able to replace her tablet if I break it, I found and installed AutomateIt. I set a trigger so that when the screen is turned off, the brightness is set to 50%.
Why trigger when the screen is off instead of when the screen hits above 59%? If you have this same problem, hold the brightness and go all the way until the screen blanks and then still holding your finger on the screen, move it all the way to the left and you will notice that the screen did not come back on. Press the power button once to turn it off and then again to turn it on and you will see the screen at the lowest brightness setting.
So, with the trigger in place, if you accidentally (or one of your rotten kids intentionally:angel raises the brightness above the threshold, simply press the power once to turn off the screen and then press it again to turn the screen on.
Just a note, I ended up installing AutomateIt Pro, Available for $1.60 from the Play Market. The free version works fine, but my girlfriend has been struggling with this issue for a couple of months and after so many hard resets, the little app is more than worth the money.
Have you tried Power + Volume Down for 15 seconds, and then leaving it alone for one minute? It will cold boot. Try that and it may work. Just saying; Hope it will help
Sorry for the necro-bump but here's the actual solution.
Problem: The video cable inside the Transformer comes loose and just needs to be pushed back in.
I can't post a link since I don't have 10 posts yet so just search youtube for the following key words:

Just fixed my blank display problem on a TF101 which is well out of warranty. Here is the link. I found the connector loose after dropping my TF101.
Thanks!
Fix lasted for a few days, now backlight dead, tried all cables again. No joy . I hate intermittent faults so ordered a Samsung Galaxy TabPRO 10.1.

[Q] Screen goes partially blank

Hey, so I have this weird problem with my G Flex 2.
I got it around 40 days ago from U.S. Cellular.
I have run into this problem about three times now, and from what I can remember it always happens when I have music playing. I tap the screen on to the lock screen then let it go to sleep or turn it off myself. When I wake it back up the screen is all black except for a few millimeters on the top, where I can see some display.(*note, this doesn't happen every time)
I am able to scroll through the display but no pop up menus. Since the battery is sealed off in the back of the phone I can't use that fix, holding the power button only brings up the menu option to turn off the screen which doesn't do me much good since I can't use the screen.
If I wait for 5 minutes or so the phone will right itself, but I don't want this to be a persisting problem. I'm not sure if this problem is tied to the music playing, it hasn't happened when it isn't playing, but I play music on my phone quite often. (note* I am playing the music from my phone, not streaming)
If you need more info I'll do my best to provide it. This is all I can think of right now.
Honestly, I don't expect anyone to have a fix yet since the phone is fairly recent and not as popular. I tried looking under G3 forums since the UI is pretty much identical, but I didn't find anything.
Sorry, my post is a little wordy.
I'd appreciate any help anyone can provide. Thanks
Yes, this has happened to me twice recently too. Once the screen was completely black except for a bright white line at the very bottom, but the phone was still responsive behind the dead screen. The other time there was a distorted/ghosty notification bar showing at the top but nothing else (like what you reported). Then the problem would resolve completely and spontaneously after resuming from sleep a few times. I have the Korean model (F510S) which was a gift so I'm stuck with it - no returns or warranty available.
bonebeatz1234 also posted about a similar problem. Seems like a hardware fault?
The replacement phone screen was fine i had a different issue of over heating and had to return it . I opted to get another device the note 4. Didn't wanna go that route bit had no choice i loved the design and ui of the flex 2. I wished lg would of just ditched the 810
~~~
Hi, I encountered same problem here.
Is anyone able to send me a screen shot or a video of this problem.
As I need to use this to prove the situation and claim warranty from the seller, however I didn't take a photo or something when the problem happened to me.
please sent to [email protected] if you have the photo or video and many thanks~
Just had this problem also had a g flex 2 for about 21 days now and it happened to me after a restart in the car with a pinkish line at the top and the phone was completely responsive even though the screen was blank
I think it might have to do with heat cause I held it by the ac vent while I was reading this board on my nexus and when I looked back at the phone it was working perfectly
But I swear during my time with the phone it heated up way more than this time and this time the phone wasn't even hot
I reset the phone like 3 times before I held it to the vent and it didn't help at all
Using the att variant with android 5.1.1
Have the same problem every now and then, found a recommendation on another website and in the instruction manual to reset the phone by holding down the power button and volume down button for about 10 seconds or to turn it off by holding down the same buttons for 20 seconds. I find what works better though is to just leave the phone alone and it corrects itself within about 5 minutes.
Having this same problem. Happens once every couple of weeks. Any updates on this?
I think that this is a heat problem....everytime i left my phone in the sun, it show me this strange error.
I'm not convinced its a heat issue. I looked at my battery chart the last time it happened and it was barely over 90 deg. It seems it happens to me when it is charging PLUS doing something like streaming music or GPS is on. I need to start taking notes. I should have done that before.
this have happened to twice too. weird anomaly.

Having the same random issue. Today it happened and reboot would not fix (it usually does) finally after about 30 minutes the screen came back to normal. I now disabled lock screen in case I need to get data off the phone from pc ? in the case that the issue becomes permanent.
Sent from my LGLS996 using Tapatalk
although it's an old post, but worth to mention, that It can happen to all the LG Flex 2 models.
It is caused by a heat or inaccurate voltage. let me explain how it can happen:
heat - when you put the phone on the car's cradle under the car's front windows during a sunny day - it will happen.
voltage/heat - when you charge your phone and not using your original charger (eg chinese car chargers) - it will happen.
so what to do? I've noticed that putting the device over the cat's air conditioning , can reduce this to few minutes. also, if you can, mount your cradle over one of the air condition outlets and it will freeze your phone all the time

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

Nexus 5 colorful vertical lines

Hello
I have a strange problem with my Nexus 5. Today when I booted it up it started fine and everything was working. After 2 hours I wanted to check my phone, but it had turned off. I pressed the power button and strange vertical lines appeared coming from the top of the screen. They disappeared after 3 seconds, but now my phone has no picture only the backlight is working. When I reboot the phone I see the stripes again, but still screen is unresponsive after booting. I know the phone works, because I hear the notifications coming in. I though, that maybe the lcd cable has gotten loose, so I opened up the phone, but the cables were still all connected. I haven't dropped my phone or anything. Can anyone please suggest me what to do? Does it have something to do with the cables? Or is the screen broken ? Any help will be appreciated.
This has happened to mines previously. Unfortunately you'll need to replace what is called the flex cable.
A lot of topics about this issue but no one answers is not complete.
In my case usb flex replacement haven't got any result. Absolutely!
Only by replacing the mainboard (i.e. motherboard) Nexus 5 became alive.
So, feature Nexus 5 rainbow vertical lines victims, keep this in mind.
ps: yes, I'm a necroposter, sorry
Same thing happens to me some time ago, now i've put some paper on the mainboard connector and the problem appear only some times.
I think i have to buy a new 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.

Yeah. Very disappointing.
I can't believe it but my screen unexpectedly revives itself after a day.

Time will tell. Intermittents are the hardest hardware failures to troubleshoot...

Agree. But I am happy that it's working fine now and I hope it will not recur.

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.

Hardware failure. May be a loose connection, cracked solder joint, trace failure on the mobo, or a bad component.
Intermittents are the hardest problems to find...

Yes, obviously. Samsung already replacing displays of those who are having this issue.

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....
