the phone reboots that way u mentioned i can connect to tv via dex mode and i can see touch working and phone working but display black
it reboots after every 10 mins i am on ketan custom rom q06 android 10
i can get phone into odin mode and try flashing stock Android 11 which i have on pc
BUT im afraid my phone might die or switch off while flashing stock rom.i asked a repair guy he says problem can be with motherboard .
im not sure to try flashing it

i managed to enter odin mod3 blindly with keys
flashed Android 11 stock firmware it was success
the phone gets On
connects to pc. connects via dex mode to tv also.
no more random reboots
but still black screen display not getting
awake only can access via dex mode or mirror mode

After around 24 hours ...
of soft reseting , stock firmware 11 install . and slapping and tapping and massaging, connecting to tv via hdmi in mirror and dex mode. my phone was in black screen of death.
everything was working. but no display. i can say that becauee in dex mode i used phome dsplay touchscreen and even spen was Workiing but no display.
last thing i was doing when display came back to life after tapping slapping soft reboots i was opening camera app and closimg and opening it multiple times. and i saw at same time display gettimg back.
when i saw a video on youtube telling to do above steps. i thought man he is joking. but literally something out of above worked
So i pray you dont get this dreadful encounter. it just saved me $400 of screen replacment which i had made up my mind on. and i coildnt go today because it was Sunday.

I have exactly the same issue. I was typing on whatsapp when suddenly screen get black. 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.
I already flashed fresh stock Android R rom and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking). I'm draining battery now with some apps that also vibrate phone. Display is still dead.
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.
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?
Hope I have that lucky as well.

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.
(Please Apply reasonable pressure on screen when trying these actions as you might break the Display)

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.

[Q] Nexus 5 screen showing colorful static

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

screen stopped working

I'm currently on holiday in Majorca, today the screen stopped working, the backlight comes on but nothing displays, I'm still getting notifications. I powered it off and left it for a while, now it shows the Sony and powered by Android screens but then goes off during the next animation
Any ideas what I can do?
I was using it for 4k video recording, photos and the only means of contacting people, currently on my wife's phone using the free WiFi in reception but we cannot use it for calls or texts.
Any help appreciated
I've used the 'off' thing under the flap a few times by the way, that's the only way I can turn it off at the moment

Without pc it cannot be done, or try to press the red button u mentioned above for 10 second let it off and charge it then turn it on
OK, left it powered off and in rice overnight, in case humidity affected it, this morning the screen now stays on but the touchscreen goes nuts like I'm pressing it everywhere, any ideas?

Haha I am having a similar issue. I think mine is registering crazy touches too but my screen flickers like hell and then eventually goes black. I left it in a rice bag for two days but didnt solve it yet. I created a thread about it here because mine was directly due to water damage. Did you dip ti anywhere?

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...

So what your saying is to try the rom and see if it fixes it? Can I have a link or something, I don't know much about roms

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.

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.

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.

My phone restart at least 2-3 times per day, every day, since the day i got it.
i'ts not even the same thing i do when it restart. sometime i just open my phone and it restart.
I have spoken with my provider, and they won't do anything until they see it restart when i'm at their shop... but you know, i can't stand in their shop all day long!
i don't think it's the same problem as you, but some of P30 really have a restart issue!
Also my P30 since when I updated to EMUI .124 restart 2-3 times a day. It also sistematically freeze during Antutu stress test (maybe it help you to show to your provider).
I just send mine to be replaced, but I'm worried that also if they replace mine nothing change...
Been using almost 2 weeks on 124. So far no reboots and just ran antutu stress test successfully.
No issues in that regard to my UK purchased device. It's been solid as a rock so far with amazing battery life also.
Maybe there is a lot of p30 with this kind of issue. Let's see how will go the new p30 that huawei will send to me as a replacement.
No problems on my end, except for a blue tint on the recents window. Using a third party launcher. Removing/ disabling Huawei Launcher gives you an older (and in my opinion uglier but better) recents screen back without that issue. Everything works fine so far but they really need to tone down their bloatware. That's the main reason why i dislike Samsung and Huawei.
only one light flashes. only the right thing works for you, how is it?
Fingerprint sensor. Works slow and flashes frequently, Mine got stuck two days ago and even after couple of reboots was still not recognizing anything. Then started working again...

Let us know if it works after replace.. I'm worried that there is a sw incompatibility with something I installed and that nothing change when I will have the new p30. It can happen that one phone have issue, but I already heard 4 case with the same issue!
On Monday I went to the beach with my family, took the phone out to take some snaps of the scenery and the with 3 x zoom, lens had the sun directly on it and the screen started to flash but only when sun was directly on the lens, doesn't sound right to me so am thinking of getting it exchanged. Anyone else had this issue?
I sent my p30 to huawei assistance and they returned back my device with issue not solved. Phone still freeze sporadically.
Hello everyone, i have a strange bug om my p30, i bought my phone a week ago and i'm sure video recording was fine at the beginning, then i applied .124 update and now when i try to record videos it just stop after 1 second, no matter what resolution or format i choose, it happens with back and front camera. I already wipe cache and data of the camera app, but no luck. Videos works fine with other camera apps like open camera etc.. . I spent a week for fine tuning my new phone , so i don't want to reset all. Someone have any other suggestion? Thanks

Did the whole screen flash or just the picture preview? This doesn't sound abnormal to me. The little pixels of the little sensor fill with light super quickly, so of course pointing it directly at the sun will make them overflow with photons and just return a mostly white image

Thank you that makes sense now
Talking to Huawei support at the moment to fix the blue tint (and maybe also WhatsApp notification/ bad video playback performance) issue. They told me they'll reach out to me today.

I have the same problem with my P30 switching back on when charging - I've only been able to overcome this by inserting the charging cable first, then powering off. Not sure about your other problem as my display brightness is always set to auto.

Seems like they fixed the flashing bug with the latest update (.153)
I'm still waiting for it (.153), but as I try to find some logic in it's behavior I guess they tried to make it kind of notification light, but it seems to be unsuccessful.

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.

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....
