Non-functional display on iPhone after updating to iOS 16: What are the causes and solutions?

Apple recently released an iOS 16 update, but it turned out to be quite problematic. In fact, many devices experience display problems after this update. What bugs can you encounter and how can you fix them?

Fortunately, display issues after updating to iOS 16 only affect some smartphone models. Specifically, the iPhone 12 Pro Max with a hard OLED display and the iPhone 11 Pro Max, which uses a soft OLED display. However, it's not impossible to encounter these problems on other models as well.

Non-functioning display, flickering or impaired response to touch

After updating your device to the iOS 16 operating system, you may notice some minor, but also major shortcomings related to the functionality of the display. Many users complain about the subtle flickering of the screen, which can be seen with the naked eye and is definitely not pleasant.
Soft OLED display devices also have problems with touch response. For example, users notice "ghost touches", i.e. activation of certain functions without pressing on the screen.
The biggest problems appear on devices that use a hard OLED display. Tests have shown that updating to iOS 16 can cause the display to blackout, rendering it completely inoperable.

What is the cause of these problems?

The non-functionality of hard OLED displays after the update is due to the fact that iOS 16 uses a new boot sequence that is not compatible with the integrated display circuitry.
In general, it can be said that the screen errors after updating to iOS 16 are primarily caused by the incompatibility of the display software with some new algorithms.

Troubleshooting display problems

At the time of writing this article, we don’t have yet a clear solution on how you can fix the display problems after the update. In some cases, restarting the device may help. In most cases, however, you need to perform a factory reset, which usually fixes the problems.
Of course, after experiencing these problems, Apple itself is also working on improving iOS 16. In the near future, there will probably be an update that could fix the difficulties. An alternative solution may be to modify the display software to make it compatible with the new requirements. This will be done with the help of special programmers that will probably be available on the market soon.
