Thumbstick drifting in neutral position of it

Hello!

Sadly i don't know how is this controller really build, but i guess it's the same problem like in xbox controller. Analog inside just got broken. If you still have guarantee just send it back. If not, you need to replace it with new one. It's called 'FJ06K-S' probably. If you have soldering iron and some skills in soldering go ahead.

Good luck

Ive dug around a lot in my index controllers because of drift and the capacitive sensor on top, as far as I can tell there aren't any official replacements online, but the joysticks just use 2 through hole potentiometers so for drift, contact cleaner might work. You can probably follow the instructions on replacing the strap to get the top open, but if you are under warranty, because of the limited part availability I would just get it replaced until they stop giving you replacements.
