Smart lock
Keeping your smartphone secure is important. However, in case you’re the one holding it, there’s no explanation on why you need to unlock your device each and every time you drag it from your pocket and unlock it. When you pick up the phone multiple times a day to look for something and keeping your phone secured, you have to do an awful lot of unlocking- be it with your face, your fingerprint, or the code you tap or swipe onto your screen.
Smart Lock
Fortunately, the Smart Lock functionality is built into Android OS for quite some years. This functionality when turned On keeps the device unlocked under certain trusted conditions to allow unlocking of the screen without any authentication. There’s Trusted Face, Trusted Location, Trusted Devices, and on-body identification. At the absolute minimum, all gadgets ought to have Trusted Devices and Trusted locations.
So, for instance, you can have your smartphone set to swipe open at home. However, if you go for a walk down the square, it will begin requesting PIN, or secret key lock. The equivalent goes for Trusted Devices—in case you’re associated with a Bluetooth or NFC gadget. If you have recently set it as “trusted” (like your vehicle or Android Wear watch), you’ll see no secure lock screen.
With Trusted Face, the smartphone will switch consistently to swipe open mode on the off chance that it spots you with the front camera. On-body location is somewhat odd, this choice keeps your phone unlocked whenever you’re holding or carrying it as long as you’ve already unlocked it.
