All f a sudden my phone has two issues. My WiFi will not switch on after standby and when I try turning the WiFi button on it just reverts to off. Also the phone gets stuck when shutting down showing a constant power off shutting down box.
Hi @swazer;
Try the forced restart/shutdown:
To force the device to restart or shut down
Thanks, still have the WiFi problem though
How do you check with third party app influence?
Restart the phone in Safe Mode and while in Safe Mode see if the Wifi problem is solved, if yes it's because a third party app is causing the issue as in Safe Mode the phone is working only with the preinstalled apps.
Restart the phone normally again and unninstall any app you may think is causing the problem until it disappears, start with any apps you installed just before the problem appeared.
Hi,
I too have this problem (XZ Premium). I think its a 3rd party app. Would be very interseted to know if you found the app which causes the problem 
Not found out which app it is but got WiFi back on after restarting and then set WiFi on permanently in settings and as solved the problem.
Just wondering.... did/do you have Cortana runing on your phone? Wondering if that's the culprit?
No, have not been running Cortana!
