Replace Camera Button on Lock Screen
On iOS 16 and later, you can customize your Lock Screen to launch OneLens directly from the camera button. This allows you to quickly access OneLens for work or school photos without unlocking your device.
To set this up: Long press on your Lock Screen, tap the camera button, and select OneLens from the list of available camera apps. Now when you swipe up from the camera button on your Lock Screen, OneLens will launch instead of the default Camera app.
