Open your camera settings and enable the 3×3 grid overlay. This grid divides the frame into nine equal rectangles. Every phone has this option — on iPhone it's Settings → Camera → Grid; on Android it's usually inside the camera app settings.
The grid is not a rule you follow blindly. It's a tool that stops you from centering everything by default. Once the grid is on, you'll start noticing where subjects land relative to those intersections.
Pro tip. Leave it on permanently. After a week you'll compose without thinking about it.
