I have a Lumia 950 and there is no longer an option to Never show the lock screen. The only reason I want to temporarily disable the Lock screen is because Groove is so stupid that it only adds music to its library while the screen is on. If you have a large music collection it can take hours so it would be nice to just let it start at night and let it get it done rather than have to babysit it and touch the screen every 5 minutes. Obviosuly there is no standard way to turn off the lock screen.. I'm just hoping maybe there is an app out there or something that is capable of preventing it from coming on.
