Random Black Square

[Zeke1234]

So I went to pick up my phone after leaving it charging overnight; first it had a yellow danger sign which left me confused because I thought I had an app opened in pop-up view; so I restarted my phone; come to find out it's damaged (which is confusing considering I haven't dropped my phone in about 2 weeks and the screen is 100% intact so there's little to no reason the screen should be this way. This is very annoying considering that corner is where I check my battery percentage and it's very annoying. (Edit/Update: it's not damage because when I use my AOD it disappears. Now comes the question which is what COULD it be?)

For reference: (Samsung Galaxy S24+ on One UI 7)

Sometimes internal damage does not show up immediately.  Drops can weaken internal components or connections and may not become apparent until much later.

Does the notification give you any indication of what the issue is?  Have you run diagnostics on the phone to see what hardware is affected? You can bring it to a repair service (you can find authorized service centers in the support tab of the Members app).  Any repairs will be chargeable, but certainly will be less than a new device.  If repair costs approach the cost of a new device (especially during holiday sale season), you are likely better off just buying a new device.  Meanwhile if your phone is still usable in its current state, use it.  But the sooner you take it in for a repair, the less additional damage will be done.

Can you provide a screen shot?  Also there are other ways to check the battery percentage - you can place a battery widget on your screen temporarily until we figure out what the symbol is and why it's there.

This is it; it won't show up on screenshots

[realaud]

Well, if it won't show up in screen shots it's not a screen defect. 

It's always there?

In all aps and on the home screen? 

Just for the record, have you tried switching to dark mode to see if the corner is still obscured? 

Does it remain when you pull down the quick panel?

Have you cleared the phone's cache partition? 

Have you restarted your phone in safe mode to  see if it's still there?

[Zeke1234]

All apps, even in system apps, quick panel and even in dark mode, will try to boot in safe mode but idk

[realaud]

If booting into safe mode does not clear up the issue, nor does clearing the phone's cache partition. You should put in an error report. https://us.community.samsung.com/t5/Tips-Tricks/How-to-Send-Feedback/ba-p/3001692

Your logs will be automatically collected and uploaded and you can also attach that photo (or a better one), but you might want to rotate it 180 degrees so that it's top side up.
