iPhone 5 home button issue iOS 8

iPhone 5 / 64GB / AT&T, previous OS: 7.1.2


After upgrading to iOS 8, single click the home button would sporadically bring up the multitasking screen, instead of going back to the home screen. This appears to happen regardless of what app I single click the home button in.


I have since performed the following:


1) Settings / General / Reset / Reset All Settings

2) Restore using iTunes, set up as a new phone


The issue persists.


I have then downgraded back to 7.1.2. The issue no longer appears. So this does not appear to be a hardware issue.


Anyone else seeing this?

I'm skeptical that any change in case will have any lasting effect.


All mechanical switches (and the Home button is a mechanical switch) create "bounce", where for microseconds when pushing and releasing the switch its "state" is not settled. Analog solutions (e.g. capacitance) can be used to address this, but software solutions would be more common in an application like this. A software solution involves analyzing the "pulses" when the switch is pressed and released, and then making decisions as to when and how many times it was pushed and released since there are extremely fast pulses on the leading and trailing edges of the switch actuation. It is this software solution that can be corrupted, or implemented incorrectly upon revision. As the mechanical structure of the switch may be different between models (e.g. Touch ID or no Touch ID) I could see how iOS 8 could affect the iPhone 5 but not 5S or later.


To me it is clearly a software change that is not compensating for the Home switch performance as well as it did in the past, hence the sudden change in performance with iOS 8 with no other changes in environment. This will hopefully be corrected in an upcoming release.

I just took mine in to the Apple Store, and of course the bug stopped happening as soon as I was in the store.


On their advice, I wiped the phone and set it up as a new phone; I did *not* restore from backup.


So far (a half day later) the problem appears to be gone. We'll see if it stays gone. If so, I guess a fresh start on the phone is the price I pay for this behavior to go away.


On the up side: suddenly I have tons of free space on the phone. 🙂

Yeah I don't use a case so that can't be the issue for me.


When you wiped, RScottC, did you restore from backup? Or set it up as a new phone?


Wiping did not work for me when I restored from backup. Right now, so far, wiping-and-setting-up-as-a-new-phone seems to have worked, but it might just be a temporary phase of not seeing the problem; we'll see.

OK. That's not the same thing I did. I actually set it up as a new phone, and lost any data that wasn't synced to iCloud. The phone was great for about a day and a half -- it didn't display the bug.


Then this morning it displayed the bug once. I thought "OK, I guess that didn't solve the problem" and I restored the backup and got all my data back again.


First time I opened an application and hit "home" I found myself in the app switcher. 😟


So maybe the full wipe just made the issue less frequent? Or it was just a coincidence that I didn't see it for a while after the wipe? Whatever, I just restored from backup and got all my data back, because why not.

I fixed it with the following steps:


STEP 1: Open an app. Any default iOS app. (Weather, Clock etc.)
STEP 2: Hold the Sleep/Wake button (Power) till the ‘Slide to power off’ appears.
STEP 3: Now press and hold the home button till the slide goes away and you get to the homescreen. Done. You’ll notice that the app is closed.

This should fix the calibration issues and make the Home button work on your iPhone, iPad, and iPod Touch.

Please stop spamming this thread with that garbage which does nothing to fix the issue and by posting links to your website you're trying to promote which is in no way affiliated with apple. This is spam and should be deleted if this forum actually had moderators.
