Right out of the box, Samsung Galaxy phones offer many ways to customize their cameras to your liking. Want an extra shutter button that you can move around the screen or want the camera to take a picture when you say “cheese”? You can do that. But it doesn’t stop there: Samsung offers even more camera settings for those who want maximum control – if you know where to look.

Samsung offers an app called Camera Assistant for recent Galaxy phones deep to the camera settings. You can turn off automatic lens switching in low light and adjust whether the phone takes a photo as soon as you place your finger on the shutter or when you remove it. It’s not exactly the kind of thing a casual snapshot shooter is looking for, but if you’re into this sort of deeply geeky menu-diving (as are we), then you’ll probably love Camera Assistant. Here’s how to get started.

To use Camera Assistant, you must be running Samsung’s One UI 5.1 OS. The app is available for the following phones:

Once the app has downloaded, you can find a new set of options by opening the camera app and tapping institutions gear icon in the top left corner of the screen. Scroll down and tap Camera Assistant.

Here’s an overview of what you’ll find there:

That’s a lot of extra control at your disposal, so go out and tinker with your camera settings to your heart’s content.
