Pressing L2 trigger also register pressing up

If this is the case. I looked up ways to solve it and by either 1: getting a pen, pencil or anything thin and press the button on the back of your controller (by the L2 screw) and hold it for 10-15 seconds. It will turn off. Turn it back on and see if it was fixed. If that didnt solve the problem then the second option is to blow into the L2 and L1 opening. I held the R2 and R1 openings so the air could go through the controller. The second solution solved my problem. If it still doesnt work look it up on youtube is my best answer. REMINDER dont blow the controller for too long! If done the controller will release a goey white substance out the head phone jack.

You mean that pressing the l2 makes your gaming figure look up as the joystick would do? If so,that is a very weird issue indeed. I’d force has something to do with it,you could take it apart and put it back together to see if something had pressure on it. For looking up and down,the joysticks are usually what are used. The arrow pads are making contact with a green plastic film circuit board,that’s also used with the l2 button. But the joysticks are usually used in most games like fortnite,to move and look up or down.

Has it been dropped at all? It’s always possible the processing chip has a loose connection..

Also,each joystick has 2 Little green squares Next to it. If you pop the green square apart,you find white looking wheels inside. These are what control the electricity flow so that the controller knows which direction you’re pushing the joy stick. If one is loose,maybe it is making contact at random.

I still don’t see how pushing the l2 would cause this only when pressed harder. But I guess the processing chip could be bad and pressing the l2 is not being processed by the chip correctly and it gets mixed up thinking you’re moving the joystick.

I also have this problem but it’s with R2 and my X button, it’ll do this when I’m playing Minecraft and usually when it does a green light starts flashing on the right side of the back of my PS4 controller, usually this is when I’m using Bluetooth so I just disconnect it and do it again and it fixes it for a little, but it’s really annoying and does it extremely often, I mean like “every 5 minutes” often

I got a controller that was doing that issue and I found a permanent fix to this problem. If resetting the controller does not work, the problem is related to the joystick (joystick drift). Sometimes it will just need a clean to the potentiometer and other times, you will need to change it but they are very cheap and easy to change (no soldering require). I found this video that should help you to fix your issue : https://youtu.be/RcIza5Zz8qY

Perhaps the physical button is sticking some in the controller body, or something sticky may be gumming it up. The micro processor itself could also be failing. if that button doesn’t move as freely as the other buttons, just perhaps it may take a little bit of modifying to the controller body by slightly widening the opening with a precision hobby knife, or a bit of lithium grease on the pivot points. If you have another controller like it compare the buttons’ range and ease of movement with the one in question. One thing might be if it’s wireless, I presume so, then just maybe pressing the reset button if there’s a little pinhole in the back with a pin or small screwdriver may force a hard reset if it’s just a software error. Or disconnecting the battery within and pressing a couple of buttons for several seconds will fully discharge the processor and then will update with correct data.

I had the same problem and I hit the L2 on the table and it fixed LOL

So I finally found a fix and all I did is the sensors were loose so I tightened the bolt from the battery pack holding the pmotherboard in pace an dI tightened it very tight

my problem is when i press L2 it does L2 again do u know how to fix it

This might help:

The contacts for the buttons of the controller are mapped onto a flexible circuit sheet.

That circuit sheet links to the motherboard via simple physical contact - when the motherboard is screwed in, a row of raised contacts press down on exposed contacts on that flexible sheet.

I opened my controller and it turned out there was some gunk or oxide on those contacts. Rub them away with an eraser, and the problem was fixed.

In my case, it was ghost presses on L2, but for your case, I'm imagining a buildup of conductive gunk might've linked the terminal contacts of the up button and the L2 button together, resulting in that behavior. I'd advise getting a full teardown guide on ifixit.com, plucking that flexible sheet off entirely, and checking the entire length of the circuit for any dirt or oxide linking the lines. Hope it helps!

I can't believe that no one even mentioned the capacitive film. It's either the contact between the film and the board is dirty or it needs a little bit of tape for better contact or the capacitive film is broken or needs replacing.

Edit: Upon further looking I see someone mentioned "plastic film" so glad I was wrong and because that's the correct answer.

So, My controller doesn't want to register everytime I play a game. I have to turn the controller off and then turn it back on for it to work. But it automatically holds the L2 button so I can't use it for some reason
