Apple iPhone 11 Pro and 11 Pro Max users worldwide complain about an unusual "green tint" on the screen right after the handset is activated.

Users on social media sites and forums have reported the issue started to appear after the device updates for iOS 13.4 and iOS 13.5. It's still unclear what causes the "green tint" issue on these iPhone 11 units, and Apple still has to recognize the display issue.

What is "green tint"?

An iPhone 11 Pro Max user on Reddit claims that the green tint appears for "a few seconds after unlocking the phone." Another user on the same Reddit thread suggested that when both the Dark Mode and the Night Shift are on, the problem is more prevalent. However, others have stated that even without the Dark Mode, the issue lingers.

Few iPhone 11 Pro users on MacRumors Forum raised the same display problem. In comparison, other iPhone 11 Pro Max users on the forum mentioned the iOS update issue 13.4.

Some users report seeing the matter only after iOS 13.5.5, while one claim that it has disappeared after the iOS 13.5.5 beta was installed.

Similarly, a couple of iPhone X users on Twitter also report the same green tint problem. Some netizens said the issue came up after the latest iOS update. It's unclear what's causing the green tint issue.

Some suggest a software problem issue and would be resolved in an update that is coming. Given reports of problems following changes to iOS, it would appear that Apple could address this with software.

That said, this is complicated because the most affected users find that taking a screenshot and viewing it on a different display does not remove any tint. Some suggest it is not at the software level. In some instances, Apple has also recognized the problem and allowed official resellers to replace the warranted displays.

Is it really a mixture of software and hardware issues?

The truth, of course, maybe that this is a mixture of software and hardware issues with a bad batch of OLED displays being affected by a fundamental shift in recent iOS updates. Affected iPhone owners say the problem persists in the latest Apple iOS 13.5.5 beta. The timeframe for a patch is unclear in either software or hardware recall.

On the plus side, the inclusiveness of iOS 14 will buy Apple time. Still, the company is now under pressure to justify what is going on. Apple has yet to release a statement confirming it.

The green tint isn't new to the smartphone world as there were issues with phones like the Google Pixel 4 and the Samsung Galaxy S9 series. OnePlus 8 Pro users reported the same problem in April, just after the smartphone's launch. In most of these cases, the issue seemed to be linked to the software rather than a hardware problem. Apple is also expected to address this issue with a device update on the iPhone 11 models.
