Another iOS 8.4 Bug - Touch ID Failure

No problem here.

After an update, one needs to use the passcode the very first time.

Same when you switched off iPhone

Same after 48 hours

Same to add/delete fingerprint.

A lot of iPhone users? They are some but compared to millions over millions it is not a lot.

Do you know how many Apple sold iPhone 5S, iPhone 6, iPhone 6+. iPad Air 2 & iPad mini 3?

My updated iPhone 5S, iPhone 6 and iPad Air 2 has no issue with Touch ID.

i get that problem sometimes and the solution i found was to hard reboot the device. simpily hold down the home and power buttons and it should work as normal! hope this helps!

Hi there..

I've got exactly the same problem as you mentioned..

Im on 5s-8.4

The problem here is my home button is dead, so cant do hard reboot..

Two phones here. No problems.

I recently began having the same issue (maybe 2 or 3 days ago, well after the last update) but in addition to loss of TouchID functionality, my home button has begun getting rather hot while the screen is off. it makes me think there may be a short somewhere within the sensors hardware, causing the software to not see the sensor and causing the heating within the button.

And, before anyone asks, I have tried powering down, soft resets, hard resets, going from backups & all the other "sure-fire" fixes that might help if it was purely software based (which I strongly doubt it is) It might not be a widespread problem affecting every (or even the majority of) iphone users, but it is happening to some of us, and hat is a problem.

Since you've positively determined the problem to be hardware, take it to Apple for repair.

That is the plan, I was just checking online to see if anyone else was having similar issues (and, from this topic even existing [and others concerning hot home buttons] they are)

Part of why I posted was to have there be another recorded account of the initial posters issue. If there is some sort of hardware failure going on with some devices at this stage of the products life cycle it would only make sense to record as much about it as possible (if people just ignore it or simply take the device in without the issue being recorded anywhere, we get into that mentality of "I didn't see the issue, so it isn't there" that is so present in society)

That makes sense except that hardware failures are not related to the "stage of the product's life cycle." Age of each product maybe but there's no way that users can validly compile that data. The same thing can be said about hours of usage of each p;product, date/location of manufacture, environment in which the user's product is maintained, etc., etc., etc.

Sounds like a hardware problem. Take it to an Apple store for diagnosis.

I have the same problem here. One iPhone 6 64... I was reluctant to update and i've waited almost 3 weeks to update, wasn't happening this before. However my case is a bit differen once my fingerprints works sometimes. And sometimes he works and just moments after I use it, it just stop working. And also my phone started to reboot when connected to my car sound, witch also never happened before.

Connect it to iTunes on your computer and restore iOS. Set it up as New. Test it. If the problem still exists take it to an Apple store for diagnosis of your hardware problem.

If the problem is not present after restoring as New restore your backup. If the problem comes back there's corrupt data in the phone's memory. You will have to set it up as New again.

i just get off from Apple Chat Support, they recommend to do a hardware shutdow reset by holding both home and lock button until the device SHUTDOWN. Then let the device off for about 5 minutes and turn it on again. Apparently it is for now working. Any further information that I can add a I'll return here.

I Have the same problem just got it today what am I suppose to do please help
