Bought a Samsung S9+ and a Clearview Case just over a year ago. The Case stopped working within a few weeks ,It doesnt seem to reconize that it is fitted. It no longer turns on/turn off when Iopen or close the case as it is intended to do.
The thing is that every time there is a system update it will start working again , the period it works for varies from a few days to at most a couple of weeks. It very annoying. Obviously there is nothing wrong with the sensor or how it is fitted else it would never work. I do not do anything to the phone or case when I am notified of an update. I just install it and for a short while the case works.
I have searched these forums and other places and the case not working seems to be a common problem, but have never seen a sure fire way to fix it.
