Iphone 4 Home button not working after upgrade to OS 4.3.1

I have had some luck blowing into the charging area and also

Clicking in a circle and over and over kinda hard ( do at you own risk )

I believe in my case and may be others it's a combination of moisyure and crude or stickiness

Affecting the contact. Alchohol cleaning too around button

Mine is working 99 percent better therefore it had up be physical Snd not software

I first had tried every software and re calibration ideas and none

Worked. Font give up if software fixes don't help.

Keep on trying the physical fixes of cleaning and blowing and clicking hard

Over and over in circles too .,, clearing what's in the way.

Worked for me.

UPDATE #2

I've now replaced both the button and the dock lead assembly (which contains the FPC connector for the button) to which no real difference was noticed, once more though, slightly twisting of the case influenced / improved the response level of the button, including with the speaker assembly removed.

All that I have left now on the list is the sub frame assembly itself and the area where the button rests against the frame.

Certainly a very interesting problem.

My iPhone 4 Home button had problems a year or so ago.

I took it in to Apple, and they told me to backup/wipe/restore.

I did that, and it worked- for about a week.

Then I enabled the accesibility mode on-screen home button and have been using it for months. Occassionally, I'd try the physical home button, but to no avail.

So today, I decided to give it a go again.

I tried killing all running apps.

I tried the 'calibrate the home button' technique.

I tried rebooting.

Hearing that it would work/stop working after upgrading software, backing up/restoring, smacking on the table, tapping on the hand, tighting screws on the bottom, holding the home button during a 'calibration', etc- there is one common thing here. The plug housing is 'manipulated'- either by the plug being inserted/removed, the jostling of a 'smack', or the extended pressure on the home button when calibrating, etc.

So - today after reading on the web, I thought a physical hardware problem also made sense here.

Here's what I did, and it instantly fixed the home button:

1- Not having my charger handy, I took a business card, folded it in half long-ways (do double it's thickness), cut it with scissors so that it fit the width of the slot.

2- Inserted in connector slot above the center horizontal, between the horizontal connector and the home button.

3- Angled it up and down a bit (as if to separate the horizontal connector and the home button.

After months and months, the home button is working great.

This really makes me believe in many cases there is a hardware issue, and also makes me wonder if this is part of why Apple decided to redesign the connector for iPhone 5... Hmmm...

Anyway, I hope this helps someone. Try it at your own risk (or success). Let us all know if it works.

Thanks.

Hi All,

Got a quick fix for you.

My Home button has been driving me mad!!

Go to:

Settings

General

Accessibility

scroll down to Physical & Motor section and turn on Assistive Touch.

You get a little symbol in the top left which will allow you control of all the buttons and record your own actions.

I.E. A work around on the home screen issue and a small element of gestures!

Enjoy!

The accessibility on screen button is not a fix, it is annoying and gets in the way of everything, and the fact it cant be placed like an icon and has set areas makes it even worse. The fact is, this thread would not have gotten to 18 pages long if the Home button was not a serious problem.

Hi Geoffro_au,

I agree with your comments, which is why I said it was a quick fix. If a vacuum cleaner or toothbrush or business card don't work, surely it is better to have an option rather than having to turn the phone off and on every time you want to get out of an app?

By the way, just so you know, the accessibility button can be moved, just drag it if it gets in the way.

Like i said, it is a quick or temporary fix that will help. I apologise if I was misunderstood, it does not fix the problem entirely.

I 've a problem with my iphone 4 home screen button which works sometimes.

Recently i found that when i press and hold the button and hold the phone upside down,button works.

also it works when i connect the charger.

"why iphone, why".

Hi im really new to this type of forum. Anyway my iphone 4 also crashed and wouldnt turn on. The soulution was to first clean the home button ( i only had some whisky available ) then did a hard restart. My phone the started up again.

Thanks to all for real practical knowledge
