Android’s Smart Lock never got much of the attention, but try it, It can do wonders. How about unlocking and locking the smartphone with Body !!
It essentially sets up your device to automatically unlock by the following methods: nearby trusted Bluetooth device, trusted location, trusted NFC tag, the device recognizes your face, and on body detection.
But since the release of Android Pay, you need to enable a security measure or else it will erase your cards from the device. \
On-body detection essentially keeps the device unlocked, ie. no need for a password to unlock it, when the device senses it is being carried. This is achieved by the device using the accelerometer and keeping track of movements. If the device is static, like laying a on a table, it will lock.
To enable on-body detection follow these steps:
- Open your device’s Settings app.
- Scroll down to Security.
- Touch Smart Lock (not available on all devices).
- You will need to enter a screen lock or create a new one.
- Touch On-body detection, switch it to on.
When you have on-body detection enabled, the device will stay unlocked as long as it senses that it is on your body. Some devices will use the accelerometer to learn the pattern of your walk, so if it senses a change in your normal pattern it may lock. If that is the case, just unlock it again and it will adapt to the new changes. When the device is not on your body, it can take up to a minute to lock. An interesting note about on-body detection is that it takes 10-15 minutes to lock when it senses you are on a vehicle.
