Have you tried a hard reset?
Hold down the power button for like 30 seconds it should reboot

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

 

[kingwicked]

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.

if this happens to you do try this before a repair

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.

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?
