Samsung’s Camera Assistant app is one of those hidden gems that lets you customize how your Galaxy phone’s camera behaves. It gives you control over things the default Camera app doesn’t, from processing and shutter speed to image quality, and there's setting in there that I use on every device: Auto lens switching.
Zoom cameras on smartphones can capture some amazing photos, but they’re often limited in low light because of their smaller apertures. To work around that, Galaxy flagships automatically switch to the main camera and use digital zoom when lighting gets tough.
The problem is, this happens even in situations where it’s not really necessary. That’s where the Camera Assistant app helps. It has an Auto lens switching option that, when disabled, prevents the camera from switching to the main lens in poor lighting. This is especially useful on Samsung's Galaxy S Ultra smartphones, which come with two dedicated zoom cameras.
If you pick a zoom level handled by a dedicated zoom camera, the phone will stick to that lens no matter the lighting conditions. Sure, it might struggle a bit in dim scenes, but it's not like digital zoom from the main camera does wonders either. So if you love using your phone’s zoom camera, turning this option off is absolutely worth it.
If you haven't already downloaded Camera Assistant on your Galaxy phone, you can do so from the Galaxy Store – here's a direct link to the app's page. Once installed, you can access Camera Assistant from the camera app's settings or from your app drawer.
