Here is the problem i have experienced with Nokia 6.1, My phone is updated to android Pie.
Phone vibration on call connect / end feature does not work at all. You can configure it in phone app as in the attached image.
I have contacted support and have tried multiple methods advised by them to troubleshoot the problem including safe mode reboot, soft reset, running tests in recovery mode but all of no use and issue persists.If this is a firmware bug then Nokia must provide its fix asap. Does anyone else experience this, if yes then were you able to get it fixed and how.? Please share your feedback. Thanks.
