Hi Kim,
This is an odd one. It doesn't look like any screen failure I've seen before so I'm afraid it's not a slam dunk to just say, "replace the screen". The half circle at the top somewhat resembles a cracked screen; if you shine a flashlight on it and look at it through a magnifying glass you may or may not be able to see an actual crack in the glass. If you do see a crack then I'd say it's a strong indication of a broken screen, but it's not necessarily conclusive if you can't.
I know it sounds wishy washy, but there's no strong indication of a screen problem, but on the other hand there's not that much else that it could be. Can you power down the phone and turn it back on again? If so, does it come back to the same screen immediately or is there anything else displayed? Does the phone give indications of working "normally" other than the fact that you can't see anything on the screen? Does it respond when you call or text it from another phone? Does it connect to a computer? Give you an indication when you plug it into a charger?
I'd say if it was mine I'd probably try and open up the back and unplug the battery for a while then plug it back in and see if anything changes when you try to power it up. In the absence of any other progress, replacing the screen is really all you've got left at that point.
Yeah, I understand about these expensive screens; I felt bad telling my niece that $185 was the cheapest I could find a screen for her phone when she broke it.
At this point it really does sound like the screen is toast; to all appearances everything else is working. I'd say the one thing you can do before you break down and order a replacement screen would be to open the phone up and try reseating the display connector. Follow the screen replacement guide through Step 14 and unplug the battery, then skip to Step 18 and unplug the screen connector. I don't honestly think you're going to find anything, but for the sake of covering all the bases, check both sides of the connector with a bright light and a magnifying glass for any bent or broken pins and check the length of the cable for any sign of tears or damage. Assuming everything looks good there, clean the connectors with 90% or higher concentration isopropyl (rubbing) alcohol, let them dry for a minute then plug everything back together and retest.
Although it's theoretically possible for the connector to come loose due to drops and jars, in practice those connectors are held down pretty securely and almost never pop off.
At this point, assuming the problem is still there, there are only two valid possibilities; one, the screen is dead, or two, the motherboard is damaged and the graphics system has failed. Since you can't really do anything about the second scenario, you're left with the first of replacing the screen as your only real shot at fixing the phone.
Most of the screen vendors will let you return the screen as long as it hasn't been installed. Which means when you get the screen, open up the phone and go to the point of disconnecting the display as the instructions I gave you earlier show, then plug the replacement screen in without attempting to mount it or even remove the original screen. You should get a picture on the replacement to verify that it's going to solve the problem. If against all odds the new display shows the yellow screen then you can put the new screen back in the box and return it.
That's the best advice I can suggest for you right now, Kim. Hopefully that will help you get your friend fixed up without losing any data on the phone. Let us know how it all turns out!

Hi Kim,
I have got exactly the same problem as yours on my S22 ultra I would like to know how you were able to fix it.

Most probably you have to replace the screen.

IMcRoni have you experienced similar issue in the past

@ifeoluwa31871 Something similar on an iPhone 14 Pro Max symptom wise yes. The screen was entirely green. The reason behind that was the frame being removed from the LCD display, because of fall damage, thus giving that green display. On Android is different though and this has never happened to me before. One thing for sure LCD displays are extremely delicate. The smallest nudge can damage the whole scren.

@ifeoluwa31871 I have an S22 Ultra myself and curved screens are delicate to deal with so they're more prone to breaking if not cared properly. If it fell you have to replace the screen. If you threw it on the bed or on the table most probably the connections are loose.
