Left shouldn't stop running, but if you need to cope, activate auto sprint, ita a great tactic too, can up and run without messing around with button presses
Left analogue drift, the reason we've had a pile of lost controllers between the two of us since the PS4 launched! Took apart, sprayed contact cleaner and didn't work. I tried replacing one a few years ago but it was beyond my GCSE level soldering. I didn't even get the thing desoldered to be honest. :(
Which kit do you recommend?
My left analog stick is broken, as in when I run forward in cod he stops running almost immediately. The right one sometimes randomly points up into the air. I've taken apart the controller and did the cleaning around as was suggested in YouTube videos, and it helped temporarily but it's back again. I'd be interested to know if there is a way to fix this properly - someone suggested replacing the analog part (that I cleaned) but I can't find any genuine or well reviewed parts.
Broke how? What's happened as I might be able to help, I usually fix these
