S20 Ultra - white/green screen of death

[AlexisCee]

Has anyone experienced, and resolved, this issue with the S20 Ultra?

During random times today, my phone's screen went blank with white and green hues. I had to perform a soft reset to make the phone work normally again. Happened again a few times more today.

I also observed that faint horizontal lines are running on the entire display.

Phone was never dropped, never exposed to moisture, and is protected by an original Samsung case. My unit is out of warranty just this June, and heading to a service center soon is out of the question as I am under quarantine. 

When I searched online, I saw that the issue is more widespread than I thought in S20 Ultra units worldwide.

UPDATE: I got my S20+ repaired free-of-charge by the Samsung Service Center @ SM North EDSA Annex, even if it is past warranty. They asked me to get certification from Globe that it is their unit, and then the claim was approved. They replaced the display, flex connector and batery. Thank you Samsung and staff of MIND ALLIANCE VENTURES, INC.

Hello I would like to ask if you have the same situation as mine wherein the S20 Plus has suddenly went into a full white/green screen? I went to SM Megamall and they're saying that they're going to charge me for LCD replacement. My warranty just got off last March as well, it's kind of odd.

If you are sure that the white/ green screen in your S20+ is not due to physical damage (e.g. dropping the phone, exposure to moisture or overheating etc), then it is very likely due to a corrupted file or software/app in the phone. In my situation, my phone will intermittently switched back from total white/green screen to normal screen at times (signs that it is not due to physical damage).
You can try soft restart of the phone to see if it switched back from from total white/green screen to normal screen by pressing and holding the "Bixby/Side button" and "volume down button" till the phone restarts.
If you are in the same situation as me, below are some steps you can try to save your phone when it is back to normal screen mode. But please back up your important data and documents before proceeding as you will need to reset your phone to factory settings.
1) Wipe out all the data and Cache Partition on Your Samsung phone as there could be corrupted cached data causing the problem on your phone by selecting:
- "Settings", "Apps", "X", "Storage", " Clear data" and "Clear cache"
- "X" is one of apps in your phone and you have to clear data and cache for all the apps that is in your phone (as you do not know where is the source of the corrupted file).
2) Power off your phone and remove the sim card and any mini SD memory card (as you do not know where is the source of the corrupted file).
3) Power on your phone and perform a Factory Reset without minimal syncs and retrieval of apps and data from your Google account or cloud (as you do not know where is the source of the corrupted file).
- "Settings", "General management", "Reset", "Factory data reset"
- you will be prompted to verify your account (e.g. google account etc) and the phone will be reset.
- follow all steps guided by the software but minimize the use of syncs and retrieval of apps and data from your google account or cloud (you have to reset to a state that is like a brand new phone). You always install the apps that you want after your phone is fixed!
Hopefully, your phone resumes to normal operation by now and you will be able to slowly manually install apps and retrieve your accounts using login id and passwords.
Lastly, i want to emphasize that i am not an expert in phone repairing but just sharing my thoughts through personal experiences with my S20+. Hope it helps!

Who would have thought. I have just had this exact same issue and to top it off, right when the date of expiry of warranty. I feel samsung should replace those with this problem for free.

Update now

Samsung's fix came a year late :(

This so called fix doesn't work for me, as a matter of fact, my S20 Ultra's green / white screen problem started after installing the update.

It happens sporadically though. Whenever the phone screen is not lit, when you want to unlock the phone, that is what triggers it.

But it happens randomly, good thing is it is not permanent, and goes away after a while of turning on/off the screen.

It is still a nuisance though, and I believe will damage the phone screen in the long term.

I hope Samsung fixes this.

The same issue I have with my Galaxy S20. This is ridiculous. I hope Samsung will repair it for free. It is their product. This should not happen. It is unacceptable!

Same problem with me just yesterday, 24 October 2023.  S20 Ultra 5G

Very very dissapointed.

i have used Samsung S7, S8, S10, S10 Note.

S20 makes me frustated.

Bye bye Samsung..
