Some iPhone 11 users report transient green tint on display
A small but indeterminate number of iPhone 11 and iPhone 11 Pro owners, and users of certain older model handsets, are reporting a bug that causes a green tint to display for a brief time after unlocking their devices.

The issue apparently primarily affects devices in the iPhone 11 and iPhone 11 Pro lineup, though it may also be present on some iPhone X and XS models. Some reports indicate that the issue has been present since iOS 13.4.1.
According to user reports on Reddit (via MacRumors), the bug occurs when a user unlocks their device. The display will appear "washed out with a green tint" for a few seconds before returning to normal.
Considering both LCD and OLED screens are impacted, the problem is likely a software bug. There is a chance, however, that an issue could be present in Apple's hardware.
If the issue is software-based, then it's likely that Apple will patch the bug in an upcoming iOS release.

Please Apple, don't release a supplemental update to fix this nonsense. It's not important that it be fixed any time soon, if it even is a real bug. If some are irritated they need to deal with their OCD. See a shrink, take some pills.
ADDENDUM: I will add that the issue of getting hot and running the battery down quickly was prior to me wiping/restoring with Apple. Also, this morning, the phone acted almost the same way. The screen still acted the same, and the battery was still running down fast, but not AS fast, and the phone was no longer getting hot. Go figure.
It is newsworthy because if your phone starts exhibiting this behaviour, you worry. It could be the start of something worse still to come. You don't know. However, if you see this is a widespread problem or that a few other users are also suffering from it (through following the news), it changes your reaction to the problem.
If no one reported on it you would basically be in the dark.
I think it’s important to remember, it’s more important how Apple responds, than the event itself.
Now back to my regular scheduled fantasy.
