Can be fixed.  What's the drifting issue on the left thumbstick? Connect to PC and use the built in windows joystick calibration tool.  Is there  a huge deadzone in the center for a particular axis or is it slow returning to the center?

You can buy replacement potentiometers from shopee to fix the issue if it cant be resolved with a bit cleaning, compressed air or adjusting the sensor.

have you ever tried pulling the stick up, then push it back down, then give it a blow? my older gen xbox controller has this issue, but once i do this it will be alright for awhile, or maybe the session im playing.

1 - buy a new one
2 - open it up and try cleaning the potentiometer Y axis area with rubbing alcohol
3 - send it to a game store to replace the potentiometer, one of my local game store in Kch here can do it for RM30 only, looks like you can get those replacement easily online, and replace them DIY if you have the solder skill

Aikilyu Gaming Console Repair Service at Kota Damansara. Can try contact them. Most console and controller can repair.

If you can't blow dirt out or get it out using rubbing alcohol, then its most likely some internal mechanical issue.  The solution is probably to replace the potentiometer.

Yep most places will just ask you to get a new joypad.  However, the parts themselves are dirt cheap and can be replaced with a bit of soldering skill but if you're not willing to do it yourself then you have to pay.

I'm not willing that's why i spent my time during the MCO trying to fix it myself lol.  I've only done simple repairs like button replacement, faceplate swapping and some simple potentiometer adjustments though.  no soldering.
