Open your smartphone easily: This hidden Android function is almost unknown to anyone

To activate Smart Lock, follow these steps – in our example on a Samsung device:

1. First set the secure lock mode for your device under “Device Security” in Settings.
2. The menu item “Unlock effect” switches to “Secure lock settings”. Tap the dot.
3. Select “Smart Lock” and enter your PIN to authenticate the functionality on your mobile phone.
4. You are now in the Smart Lock menu. Here you can access the following options:
   Reliable devices: You classify one or more devices as “reliable”. If the smartphone is close to these devices, it will open automatically using Smart Lock.
   Reliable locations: You choose where the phone will never open.
   Reliable voice: You can use your phone voice recognition to determine if you are using it.
   Wear recognition: By authenticating certain operating systems, Smart Lock authenticates whether or not you are currently carrying your mobile phone with you. Your phone will open automatically accordingly.

But the smart-lock feature cannot be used only on Samsung devices. Since it is part of Android, you can find it in most device settings – look for “Smart Lock”.
