Add Trusted Devices to Smart Lock auf OnePlus
Smart Lock on OnePlus phones offers two ways to skip the lock screen automatically: trusted locations and trusted devices. A trusted device keeps the phone unlocked as long as a paired Bluetooth accessory, such as a smartwatch or car system, stays connected. Unlike trusted locations, this option ignores GPS accuracy and reacts purely to the Bluetooth link.
Before you can add a trusted device, pair it with your OnePlus phone via Bluetooth first. Smart Lock only lists devices already known to the system, so an unpaired accessory never shows up in the selection screen.
To add one, open Settings ➔ Security & lock screen ➔ Smart Lock. Confirm your current pattern, PIN or password, then tap Trusted devices ➔ Add trusted device and follow the on-screen instructions to pick the paired accessory.
The phone stays unlocked the moment the Bluetooth connection is active, even if the accessory is not in your hands. Remove devices you no longer use from the trusted list to avoid leaving the phone unprotected. If you mainly want automatic unlocking at home or at your desk, a trusted location is usually the safer option since it depends on your position instead of proximity to a device.
