Power/Lock button not clicking, difficult to press

Hi there,

Yesterday the power/lock button on my iPhone 4 stopped having that satisfying click when I pressed it. At first I thought it was just that my phone is getting old and losing the nice tactile feel, but now it's getting harder and harder to get a response out of the button.

It does still work if I press it hard enough and in just the right spot, but it seems to be getting worse as time goes on. Right now I have accessibility settings enabled so I can sleep my phone without the button.

I've read some guides on here and I'm not sure exactly what part I need (or if I need a part at all). I don't believe it's the button itself that needs to be replaced (if anything it's probably the inner mechanism), but it seems a few people have been successful in fixing this problem without replacing anything.

I don't want to take it in and pay obscene amounts of money to have it fixed and I know a few people who are good with electronics so I'd just like to order the part, but I'm not comfortable taking the phone apart myself.

I am not sure is there any way to solve this problem but i am sharing one of my friends experience after he got such kind of problems.He goes to apple store and let the Mac Genius know about his problem and he said it is a hardware defect and went ahead with the swapping process. They had some replacements in the back.It looks like the genius nicked the chrome bezel with the charger cable edge, and there is a bit of a light leak.

Here is a video of this problem solution you can check it too -

I'm in the same boat. As @wawan says, seems like the "flex" that makes the button feel clicky, not any electrical components. I don't see where to buy just that part or any reference to about how to fix just that item. It would be fixed by replacing the whole button and/or power button mechanism, but don't want to go through all the trouble (and expense) if not necessary.
