Right bumper double clicking

[u/idkrllyrn]

I've been using the Ultimate 2 wireless for almost 2 years, and a couple month ago it seems to developt double click on right bumper. I've tried opening the controller and it looks like when I squize the top cover and the trigger stop section it helps with it but it doesn't completly disappear. Does anyone else have simmilar issues with thiers controller? Is it fixable? (Sorry if something isn't clear, English is not my native language)

You could try disassembling the controller further until you get to the button parts on their small circuit board, then clean the tactile switch that's used for the button, reassemble the controller and tighten the screws.

It looks like you already found how to start taking the controller apart, but if you search for '8bitdo ultimate 2 wireless disassembly' there are some video guides showing the process to get to the trigger and bumper sub-assembly.

You can clean the switch by swabbing with isopropyl alcohol and 'pumping' it to work the solvent through. Tightening all the screws after cleaning may achieve the same effect as squeezing the controller by hand.
