In the picture in tutorial camara is in fullscreen but in my phone (Xiaomi Mi A2) just use 80% of the screen and i want picture cover all screen.

Anyone know how set fullscreen for camera?

Hello,

Welcome to our Microsoft Q&A platform!

The camera sensor is 4:3. The screen is usually 16:9. The sample code choose to show the entire camera preview, so part of the screen is not filled. You need to stretch to fill the whole screen, however in that case the images captured include areas not shown in the preview.

If we really want to do this, we can try to change the android native code in android platform.

please pay attention to class CameraFragment.cs in sample CustomRenderers/View/.
