I don't make a habit of counting how many times I unlock my phone, but I'm willing to believe the stats that say the average user does it hundreds of times each day. That can be an unnecessary chore when using a device in a place safe from malfeasant interference, such as your home, which is why Google has now introduced the option to add trusted places to Android 5.0's Smart Lock. As with the two existing options, trusted faces and trusted devices, the new location-based automatic unlocker bypasses the usual lock screen when it detects the proper circumstances. You can set multiple trusted locations and it works without adding any delays to accessing the phone.
The update to Smart Lock comes as part of the latest version of Google Play Services, which is propagating to Android Lollipop devices right now. I had to download it directly from APKMirror, but so long as you're running Google's latest (and best) software, it shouldn't take too long to reach your device as well.
