Lenovo k3 note VR mode switch disable

Android are giving update to Android marshmallow to the lenovo k3 note users and other, but after updating many of us have habit to go through features available after updating to marshmallow and hence sooner or later we disable the VR switch mode from setting.
This is where the mind got puzzle after updating mobile as it cant set back on and shows that "switch on the micro screen to turn VR switch on".. Now what you do !!!!
As no option like micro screen is available in setting and hence you only think of factory resetting!!! But wait there is a way to handle this...
Just follow these steps
1. First go to the right upper side of notification where you find a icon of owner or a photo if you have set one.
2.Now click on it another window open where you find owner and guest, then click on guest.
3.after that you will have new homepage open, similar to owner.
4.In that go to settings > feature >VR switch mode > turn it on
5.Bravo!!!! Work done .now go back the same way by clicking right upper owner icon and now you can use Virtual Reality option ..enjoy!!!
