Use Smart Lock on your Galaxy phone

Your phone is so smart, it can unlock itself for you. The Smart Lock feature automatically unlocks your phone by recognizing different signals. For example, it can recognize your phone's proximity to your home’s wireless router, your car’s Bluetooth system, or your smart watch.
Note: Available screens and settings may vary by wireless service provider, software version, and phone model. Smart Lock is not available on all carriers.
Available Smart Lock features
If you hate constantly typing in your PIN or password, use Smart Lock to keep it unlocked in certain situations. Just remember, you'll need a lock screen set up before you can use this feature.
From Settings, tap Lock screen, and then tap Smart Lock. Enter your lock screen credentials, and then tap GOT IT.
The following options are available:

On-body detection: Keep your phone unlocked while it is on you. Just unlock it once, and it will stay unlocked as long as you're carrying it.
Trusted places: Add a location where the phone will stay unlocked.
Trusted devices: Add a trusted device. Your phone will remain unlocked when it's is nearby or connected to the trusted device.
Voice Match: Set up Voice Match. This will let the phrase "OK Google" unlock your phone.
