The iOS/iPadOS 13.6.1 patch doesn’t just alleviate the sickly screen tint.

It also fixes a couple of other iPhone/iPad bugs, so it’s worth installing the patch even if you haven’t experienced the green display issue.

One of the squashed bugs is a frustrating data storage error wherein unnecessary system files were not being automatically deleted—something iOS is supposed to do when a device is running out of free storage space—causing iPhones to fill up with junk files.
