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.

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....

    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...
