To get started with the debug mode, you’ll need to have an AirTag connected to your device.

It’s a bit of a confusing screen, since users were likely never intended to see it, so you’ll want to make sure you don’t adjust anything that you might lose track of.

The debug screen—for as long as Apple permits you to access it—lets you adjust how the Precision Finding screen renders, but you probably don’t need (or want) to mess with how many dots appear on the screen.

Most importantly, the bottom four sliders are what you’ll use if you want to adjust the color you’ll get when you’re locking in on your missing AirTag.
