How to enlarge the face of Xiaomi mobile phone?

Open the camera application on your phone. Select the recording function. Click on the three bars in the upper right corner. Click Settings. Click the volume button function. Just select zoom. This way, you can use the volume button to zoom when shooting video.

Zoom is another focus of the lens, focusing on zoom ability. The so-called zoom capabilities include opticalzoom, digitalzoom and Hybridzoom. Although they are all helpful to enlarge distant objects when shooting at a distance, only optical zoom can support adding more pixels after the main body of the image is imaged.
