Apple recently released watchOS 9.5.1 update for all compatible Apple Watch models. The new firmware focuses on fixing bugs found in watchOS 9.5 and improving the stability of the operating system. But users complain that some problems still persist. The new version was expected to fix the screen problem that first appeared after the release of watchOS 9.5. However, the problem with the green tint on the screen does not seem to have been resolved.

What's more, some Apple Watch owners say the situation got worse after installing watchOS 9.5.1. It is unknown if a fix has been made for the onscreen error, as Apple has not disclosed what fixes it has made in the release notes.

It's worth noting that not all Apple Watch owners experience this problem. There are also users whose green screen issue disappeared after installing watchOS 9.5.1. You can download the update from the General > Software Update section of the Apple Watch app.
