It`s the same reason that joysticks on every controller drift: the same parts are used. The PlayStation 5 might be really hard to find, but there`s one feature you aren`t missing if you`re still using an older console: joystick drift. Just like the Nintendo Switch, or the PS4 DualShock, and even the expensive Xbox One Elite controller, the analog joystick has a drifting problem.

Unlike D-pads, they can cover a wide range of motion at almost any angle and it takes a lot of pieces to do that. To make things more complicated and to provide better user feedback, they`re analog instead of digital. That means the amo...
