My sprint (L3) button regularly fails mid sprint

i reckon shelve it, rectal

I actually opened up the controller, got some WD-40, sprayed once (lightly) inside the L3 analog as it can loosen up the stick and let it sit for about 30 mins and reassemble everything and it's been working for ever since. It is kind of tedious and also have some patience because you can easily tear the ribbon cable that connects to the motherboard if you're not careful.

I recently got a scuf impact and two weeks into using it got the same issue but I managed to fix it so if you have a normal ps4 DualShock then I think you might have to open up the controller if moving the joystick up and blowing in it doesn’t work. I used the scuf thumb stick key to open the left ring and I took the thumbstick off then I literally just blew in it and put it back together but I reckon wd40 might work a bit better if you have it at home.

Hope this helps!
