There are a few different apps that I’ve tried. I believe that they all use the WiFi network that you are connected to in order to determine whether it is “safe” to disable the lock screen. So, essentially you flag your home and/or work WiFi so that whenever you are connected, the lock screen is turned off. On one phone, Unlock at Home worked great, but on another phone it was not reliable. The best app I’ve found is SkipLock, but after a free trial period, you have to purchase it for $4.99. That is a little steep for what seems like a simple app, but on the other hand it works and saves a lot of unnecessary unlock screens. Honestly, I would try the free Unlock at Home app first, and if you aren’t happy with that, try SkipLock. Both of these are on Google Play.
