Cannot answer calls after the latest update even though the phone is ringing

After updating yesterday, I am not able to answer calls.
The phone rings and vibrates, but the display stays black, or if I am using the phone at the moment, nothing will change at the display. Which make it impossible to answer the call.
Anyone else who has experienced this after updating, or has any way to solve the problem?

That is exactly the version I have updated to yesterday, which has created the problem.

I know, my reply is just a link to my answer in the other topic (sorry it didn’t help).
Perhaps here’s something for you …

Solved in another topic. Please don’t start duplicate requests.
