Hi, I have faced similar problems(to be specific it’s the PS button, repeatedly turning on and off ). SOLUTION: i removed the whole case. You will find the silicone rubber key pad….which is a little loose meaning it’s close to the PCB contact patch, that means it constantly makes contact with the PCB pad with little or no force from the user. all you have to do is put the rubber silicone back into those two tiny pole like structure that holds it in place and adjust it so that it doesn’t come off. FORTUNATELY that solved my problem. also please let me know if it works or is it just a temporary solution. Thank you.
