The problem is the springs and little clips being too fiddly to put back, I have no feeling in thumb and index finger and they keep popping out trying to put back. So, I was wondering what can be put in the place to replace them? The issue was the button was stuck in and taking the case off revealed the spring had popped out, I thought this might be easy to put in but was confused what order to go back in so I carefully removed the working button to make a bigger mess :(
