What’s the innovation behind Google’s new Android smart lock?

On March 23, according to foreign media reports, Google launched a new Android "smart lock" feature. This feature uses the accelerometer of the mobile device to determine the state of the device. If the device determines that you are using the device or the device is in your pocket, the smartphone will remain unlocked. The official name of this new feature is "on-body detection". This feature is mainly for users who are willing to sacrifice a certain degree of security but gain convenience. It is very important to ensure the security of the phone, but it is undeniable that we may unlock the phone dozens of times a day, and many times it is not necessary at all.

The official explanation of "on-body detection" means that this feature will disable the lock screen function, but restore the lock screen when the user puts the phone on a table or other surface. For example, when you first pick up the phone and try to use it, you still have to unlock it. But after that, as long as the user holds the phone in his hand, puts it in his pocket or wallet, the device will remain unlocked. Once you arrive at the office and put the phone on the desk, the device will return to its normal locked state.

Of course, the feature can't determine if it's you or someone else using the phone. It just uses the device's accelerometer to determine if the device is constantly moving. So if you give your phone to a friend or it's stolen by a pickpocket, it's likely to remain unlocked. The security option will be available soon, and Nexus and other Android phones will soon be able to get this feature through an update to Google Play Services. In addition, it joins some very useful new security options, such as trusted places, trusted devices, and trusted faces.
