Got an answer on my ticket regarding the ghost touches now. Quote:
Hello,
I hope this message finds you well.
You are receiving this message because you previously indicated you’re experiencing issues with your Fairphone 4’s display. Our Product Team worked hard to understand the root cause of this issue and come up with the most sustainable solution.
Our investigation showed that this issue is very complex and is caused by a combination of hardware and software factors. Until now, we were able to help most of our customers by sending the device to our repair center.
Now we are here to share some good news with you. We discovered a long-term software solution, which will be included in the upcoming software update for Fairphone 4 at the end of August. After the update the display issue with erratic touches should be resolved without a need for a screen repair.
If you need a solution sooner or if the issues continue after the update, we’ll be happy to arrange a repair for you.
In case you have recently sent in your phone for repair, rest assured - our technicians will return the device to you with a well-functioning screen.Should you have any further questions, you are more than welcome to reach out to us again and we would be happy to assist you further.
Have a nice day and take care.
I stay sceptical, but at least they now finally seem to take care of the problem.
