I wonder if somewhere, in some dingy bar in the bad part of town, there's a betting pool for this. :)

I just literally spent days last week helping a friend who had 40gb of other data on her iPhone 11. We tried everything and opened a dialog with Apple who was like sucks restore the iPhone. Ended up doing a full backup and restore to clear it.

Yes it happens but I am annoyed. iOS 13 somehow is still a dumpster fire nearing the end of its life.

The green tint issue is related to thermal management? Every time I've had a green display on my 11 Pro Max was upon first wakeup usually in a dark environment with the brightness almost to 0 (only lasting a few seconds). Interesting.
It's funny, I wake up my phone a lot in pitch darkness and I've never once seen this issue, but other people report seeing it all the time.

Makes me wonder if there was some revision of the hardware that exhibits the problem and not all of us have it.

I have a release day iPhone 11 Pro Max here.

A few days ago I fully deleted the Files app and shortly thereafter reinstalled it from the App Store on my iPad Pro, I got more than 10GB back only doing this.

I make huge file transfers from my Mac to my iPad via AirDrop, and for some reason I don't get all the storage back when I delete the files from my iPad, the only way to get back all the storage used by the deleted files is deleting the Files app.

For those wondering if it's safe to delete the Files app and then reinstall it from the App Store: yes, when you reinstall the Files app back, all your iCloud and local files are there untouched!

I guess it's an AirDrop bug.
