Zfold 5 went haywire then my screen wouldn't respond to touch

[userkdzbwG3AMA]

Cancel button stuck on screen and the UI error polled up when I double tap anywhere on the screen. I think it thought my YouTube video i had open in the background was being moved around the screen? Its a YT premium feature to have picture in picture mode for videos. Opened a video and suddenly my video came out of full screen and started moving the video around the screen before it disappeared. I have the latest version of One UI. What the heck is happening? Drop down menu worked, but I couldn't tell the screen recording app to start. Anyone else run into similar?

Another oddity i noticed- upon restarting my phone to escape that weirdness, I had an open tab talking about Google criteria and information for paid promotions. The video i had opened was mentioning them. Upon returning to the video I couldn't replicate the issue.

@userkdzbwG3AMA That sounds like you have a malicious 3rd party app causing the issues. As a troubleshooting step you can boot into safe mode. If the phone operates properly while booted in safe mode, you know that the issue is caused by a 3rd party app.

Next time it happens, lock and unlock the screen to see the response. Also, do a screen calibration and diagnostic if you have not done so already.

Lock and unlock was possible but the screen just went back to that. I'll do the calibration now
