Have you installed an app recently that might have changed its settings? Does it work in safe mode
Lenovo p2, love it and the battery creams the note 4.
...The phone is still performing ok, some odd moments now and again, but nothing too major.
I found a refresh of the firmware using Smart Switch cleared the minor glitches I was having.
I am just installing smart switch now, is it self explanatory?
That's what took out my previous Note 4, will check - thanks.
Edit - app says it's all OK.
