I put screens and home buttons on a couple of iPhone 4 handsets.
It's no fun, that's for sure.
Now in less than a year, this 4 is just beginning to need a home button cleaning.
I have some part coming from Hong Kong in a few weeks to fix the front light sensor.
That'll require removing the screen anyway, so I can do the button at the same time
From what I've observed, it's not the switch ( even though I put in new ones), and it's not really the button, either.
I think it's an accumulation of dust & skin oils between the button and glass screen.
(If ya think it's the switch, I'm willing to reconsider.)
I have read every crazy cleaning idea I could find on YouTube, and tried them.
None really worked, in spite of the claims.
I've considered various ways to delay the problem in a newly cleaned phone.
- silicon lube on rim of button
- graphite powder (used for locks) on button rim
- case that is sealed around home button
The first two aren't very workable.
The case will probably be bulky.
I have some Otterbox-like cases coming in the same shipment.
Fresh ideas are welcome.
