The angle finder feature makes it easy to measure the angle and make sure something is aligned.If the lines look a little uneven (not quite straight) when you first open them, just press the calibrate button and follow the instructions.
Translated instructions: simply place the phone on a flat surface with the screen facing down after pressing the button until the timer expires.
