Have you tried powering down and back up?

The only way you can see "text like a pc" IMO, is if your phone is jailbroken, a complex procedure that even I don't do.

Or, you somehow have a "shell" app running, but you can exit that. It's just an app. I have two on an ipad.

Both are highly unlikely for an average user.

Try the restart. It's 2 days to a full moon, if that matters. Good luck.

I presume you're not just stuck in a text editing app. ??? If so, quit it. Double click the thumb button or swipe to see running apps.

All of a sudden the mobile version is back on my iPhone. Weird. Didn’t do anything to change it either time.
Just parking this here.
