Apps and features
Locking the focus (AF) and exposure (AE)
You can lock the focus or exposure on a selected area to prevent the camera from
automatically adjusting based on changes to the subjects or light sources.
Tap and hold the area to focus, the AF/AE frame will appear on the area and the focus and
exposure setting will be locked. The setting remains locked even after you take a photo.
This feature is available only in Photo or Pro modes.
Scene optimizer
Your device will adjust the colour settings automatically after recognizing a subject or scene,
such as people, food, or night scene.
On the shooting modes list, tap Photo. When the camera recognizes the subject or scene, the
scene optimizer button will change and the optimized colour will be applied.
