Hello! This thread really helped and I hope this post does too for anyone with this issue. My SteamDeck fell on the ground and the L1 button stopped registering clicks on some parts of the button and didn´t make the "click" sound (the outermost and middle clicks didn´t register/make a sound, but the innermost click did). Anyways I opened it up and realised that the issue was that the L1 button had been slightly raised due to the fall, meaning that only some areas registered a click. To solve this, I had to raise the edge of the SteamDeck by less than 1mm to ensure the L1 Button registered all clicks. To do that, I inserted a very thin piece of paper between the case edge and the long lever that the L1 button has. This solved the issue and the button registers all clicks now.
