An AirTag owner accidentally discovered the existence of a hidden developer mode in the surface when he frustratedly tapped the name of the AirTag several times in a row. An overlay appears here with various parameters that can also be adjusted.
Apple AirTag – Developer Mode Overlay
The Reddit users tried to pair his AirTag four times in vain. When it was finally done, he received a weak signal from the Apple AirTag at a distance of less than one meter. Out of frustration, he clicked several times on the name of the AirTag and thus activated a developer interface on which some parameters can be set.
So if you want to try it out, just click on the name four times. The first two sliders refer to the blurring of the camera and the brightness, the other four define the color of the screen, which it takes on when you approach an object. If you change the values, it is best to make a note of the original values. With the slider, the values can be reset if you double-tap the value at the front.
Certainly published unintentionally and Apple will probably add it with the next update and remove this function.
