By setting up the Smart Lock feature, you can keep your phone unlocked when you are holding it or at a specific time or place. Check the guide below to set when and where your device stays unlocked.


Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps:

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install.

Step 3. Follow the on-screen instructions.

You can set your phone to unlock itself and remain unlocked when in trusted locations or when other devices are detected. For example, if you have set your home as a trusted location, when you get home your device will detect the location and automatically unlock itself. First, you need to set a screen lock method before you can use this feature. To set the Smart Lock, follow the steps below.

Step 1. Launch the Settings app, and then tap Lock screen.

Step 2. Tap Smart Lock and follow the on-screen instructions to complete the setup.

Step 3. Tap on the Smart Lock type that you want to use. You can check the guide for each Smart Lock type below.

You can keep your phone unlocked while it is on you. Just unlock it once, and it will stay unlocked as long as it’s in motion, like when you’re holding or carrying your device. Your device will lock when it detects that it’s been set down. To enable On-body detection, follow the steps below.
