Touch ID no longer working with iOS 8.4

Had the same issue. Starting the new Music App once solved the Problem.

No

What solution? I have tried everything here except for go to an apple store, which I don't have nearby.

I got the IPSW from iTunes. I used my MacBook Pro with Yosemite and I pushed restore iPhone. Am I the only person with the Touch ID problem?

You did not indicate that. Most individuals when reporting they download an ipsw, means they picked it up somewhere else and forced a restore with it, rather than letting iTunes download and install the correct ipsw. As far as you being the only one, there are the few listed here. I've not witnessed any others. See this listing from Apple's support document on Touch ID.

1. Make sure that you're using the latest version of iOS.
2. Make sure that your fingers and the Home button are clean and dry.*
3. Cover the Home button completely. Don't tap too quickly, don't press down hard, and don't move your finger while Touch ID is scanning. Make sure that your finger touches the metal ring around the Home button.
4. If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring. If it does, remove the case or screen protector and try again.
5. Tap Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on. Also make sure that you've enrolled one or more fingerprints.
6. Try enrolling a different finger.
7. If you can't enroll any of your fingers, take your device to an Apple Retail Store, Apple Authorized Service Provider, or contact AppleCare for help.

You're right. In fact it worked just once and dropped dead again....

I think I've tried all of that. I will try to wait for an update or contact apple support. I restored my device with the software iTunes downloaded, which is compatible with my phone, i'm assuming.

Only you would know if you tried all of that. There would not be an update unless there was a widespread problem, and contacting Apple Support is what is listed there in the material I provided. I suggest you make contact with them.

Thank you. I will hope Apple is notified of this problem, I will leave feedback and report the issue, and I will wait.

This bug is not a general issue with the scanner. Touch ID works fine with all apps where I use it for verification. It's just the lock screen that keeps locked. The FP is scanned and the 4 dots are filled. But the s will not unlock.

I Found out for my iPhone 6 with ios 8.4 that the touch id didn't work for anything. Oddly enough my phone was plugged into a charger and I took out the charger and it worked!!!! And I tested this theory by plugging it back in and that for some reason affected my Touch ID and when it was unplugged it worked fine!

IDK if this will work or if this Is your problemo but thought I'd mention it

go to settings ----> touch ID & passcode ----> make sure at the top where it says use touch ID for: you turn it on for iPhone unlock. When I updated my phone it shut it off automatically

Mine has sstill been working on and off. 50% of the time.

Has your display been replace by a third party( Not Apple)?

Has it come in contact with liquid?

Restore the device and setup as new. If the issue persists it is a hardware issue.

No. It was replaced by apple. (The whole device) I have restored it completely with iTunes. It's the same.

If you are within 90 days of that replacement then you will be covered for another replacement through the Apple Store.

If its been longer than 90 days you will need a display replacement and it would come with a cost.
