Despite being laced with a spec that allows you to see your phone screen light up once any notification pops in, users are facing issues with this. Also, you may have to bid goodbye to data toggle on the home screen as well as on the quick settings on the OnePlus One. A plausible solution could be getting the Data Toggle 5.0 app on board. Again, this is possible when the phone is rooted. The worst drawback when you update your OnePlus One with the new OS is non-availability of lock screen widget. We indeed loved the feature that allowed us to create a custom button for volume adjustment on the CM11 OS fed OnePlus One but with the brand new CM12 update, this is just a thing of past.
