S23 Ultra dead screen shortly after updating to One UI7

[adamkarbh292]

Hi, after like two months of waiting i upgraded my Samsung S23 Ultra to One UI 7 like 3 weeks ago and after that i started noticing my phone was acting kinda weirdly. Apps we're crashing for no reason but the main reason is that first happened few days ago. System UI started lagging like crazy and with it the screen was flickering, showing horizontal lines, but yesterday when i tired to back up my data and wanted to reinstall my phone back to one ui 6.1, the screen just turned off and did not showed any signs of life but phone was still turned on and seemed to be working. I want to ask here what can i do because the phone is out of warranty and i lost the box with all papers while i was moving from my old apartment. Thanks for any help and support😃

You'll have to contact some tech support either Samsung or some other trusted

From that pic, the left seems to be a few pixels higher than the right. As a me thing, I don't think the screen itself is at fault. I'd guess the cable or something that sends the screen the data is broken. As if the screen itself was at fault, it'd be a uniform line. Doesn't help you fix it but it could make the repair costs less if the display itself is still fine
