Simple Camera – can be used for photo and video shooting. You can switch between the front and rear cameras, limit the shooting resolution, and choose a save path. The flash can be turned on or off as a flashlight. You can use gestures to zoom in and out.
If you want this app to run when you press the physical camera button, you will have to disable the standard camera app in your smartphone settings (Apps -> Camera -> Disable).
This app will not show ads or ask for unnecessary permissions. It is fully open source and has a dark theme.
