Home Button Mechanical Repair (Not Replacement)

Dear Sir/Madam,

I would like to repair one of my iPhone 5s's home button. My problem is nothing related to electronics. I am asking if there is any way to fix mechanically.

It's the original button and I am so afraid to mess with it. But the button doesn't give same smooth feeling as my other iPhones.

If there is any way how to disassemble the button and replace or modify the mechanical parts, where spring is placed.

If I could access to that part, I could simply replace the spring from 3rd party button's or stress it by pulling a bit and put it back in.

But when I see the button, it appears to me there is a very strong glue used to embed electronic part, finger print sensor.

I have searched a lot on internet to find any instructive video or an article but couldn't have found any.

All instructions are simply based on replacing the button, but it is not repairing the button.

I believe that this is one of the high risk operations, hence there is no true alternative to the original home button for all 64 bit devices with touch ID, finger print sensor.

But still it would be very useful to have an instructive video.

Regards
