Duelsense Stick Sometimes Drifting?

Here the problem is this. At the factory after the thumbstick modules are installed, each individual controller is then hard calibrated in it's own individual chip. Because graphene based pots are never precisely accurate. You can get brand spanking new pots and they are "perfectly fine" but because that individual controller was calibrated for the pots that were originally installed.......those new pots won't work "correctly". This can result in drift and or game breaking outer circularity errors ( example: tilting all the way but the character only walks instead of run).

Since (unlike Nintendo) Sony does not give us a way to recalibrate on the software side, it's a game of hit and miss til we find a pot that "agrees" with that individual controller. There exists "drift correction" flex board units with small pots you can install that give you some control over fine tuning but I recommend against those because they always mess up the outer circularity (take from the outside to give to the inside).

Personally I no longer do stick drift repairs using graphene based potentiometers. I just junk those in the trash and install Hall Effect modules. Hall Effect modules can be calibrated at the hardware level and won't (in theory at least) ever drift again. I have also as of yet never come across a Hall Effect module that had game breaking outer circularity errors. Consider ditching the graphene and going Hall Effect.
