I have a problem the compass of my phone does not work even when I calibrate it a thousand times... Moreover when will android Oreo be released??

I suggest to update your device to the latest firmware version and after that perform a factoy reset.
Oreo update may come in future, but no official infos or ETA at the moment.

I tried but it did not fix compass issues...maybe something interefes with the magnetic field inside the device ....Please fix this problem 

If anybody else can confirm such issue, i'll forward it to the tech team.

I've the same issue… compass doesn't work well and I cannot calibrate it.

Forwarded such issue to the tech team, to be fixed.
