Using 2x lenses cause error (cannot acces camera)

[pblasi]

Camera modes which use the 2x zoom lenses work fine for a while. Suddenly, when switching to 2x zoom in normal mode or switching to portrait mode (which uses the 2x lenses) causes a camera freezing and message appears: camera error, cannot access camera. MIX 2s (polaris) with Pixel Experience rom. (Tried on LineageOS too, same issue)

Portrait mode is little buggy, we use closed source miui libs. might be caused in some cases when camera is not released properly.
