Record videos while phone is locked
There might come a time where recording a video can save your or someone else’s life. However, going through the whole unlocking process can make it difficult to access the camera on time. So, if you want to open the camera even while your phone is locked, there’s a simple trick you can do.
While locked, tap the Shutter button your camera. Slide the camera icon to the right until it’s halfway up but don’t let go yet. Keep sliding the camera until you reach the video option. Next, double-tap the Home button three times while keeping your finger on the slider. Your phone should be recording. Unlock your phone as usual to stop recording.
