I have experienced a slightly similar issue. The major difference is that when I press the power button to turn of the screen and press it again to turn it off, the issue is resolved.Another extremely annoying bug I'm getting with the Pixel 8 Pro - occasionally (say once every two or three days), the phone becomes completely non-responsive to touch.
I've managed to record a video of the issue this time - the phone is able to unlock because it's using face unlock (hence why I have to lift it up to unlock it), but the screen won't respond to touch at all, despite me frantically swiping and tapping on it. It freezes like this for about 30 seconds to 3 minutes before it'll start responding to touch responses again. On Monday, I had phone call coming through can I literally could not answer the call because the screen was frozen and wouldn't respond to my touch.
So extremely frustrated with the phone. Anyone have this issue and know of a fix? I'm guessing if I go to Google I'll get the usual 'update apps, update software, clear cache and finally, do a factory reset. Oh it didn't fix it? Ok we'll escalate this to our level 2 technicians' and I'll never hear from them again.
I just don't get why there are so many issues with these phones.
