Chosen Solution
When I press the R2 (right trigger) the left analog stick moves (not physically) to the left. It is interfering directly as I saw it using the DS4windows software to analyze the input data. What might be the problem? Hardware? Software?
Some years passed i see - but maybe someone will use it :) I had this problem too and it was solved by cleaning potentiometer on X (up and down) axis of Left Stick. Its a small disk like thingy inside left stick. This video shows it preety good https://www.youtube.com/watch?v=4AkDIzKq… - however i didnt replaced the part but cleaned it with tissue paper. There was some dirt or rust, i dont know. However be careful because as told in video you can broke it easily. It really sound strange but it worked - i cleaned it about 2 weeks ago and the problem vanished :).
Hey, i’ve been expiriencing this issue, if you want it to stop just pull the joystick out, point it to the right and give it a good blow in the hole that appears on the left side
hardware. the ps4 uses a see through circuit board to register button presses. it could be as simple as buying a new see through board or just cleaning the present one off with some alchohol.
I have the same problem except the motion down instead of left or up
