Q: Touch ID not working on iOS 10 -iPhone 5s

I don't know why you are having these issues. Perhaps you got a corrupted update which is not common but does occur.

Try this to see if it helps:  hold down these buttons at the same time for at least ten seconds, until the Apple logo appears:  a) the Sleep/Wake button and the Volume down button (iPhone 7 and iPhone 7 Plus) or b) the Sleep/Wake button and the Home button (all other models)

If a restart does not help try a System Restore. First backup your device using iTunes. Also import your photos to your computer and copy all important data if possible. Try restoring from backup first and testing it. If it does not help, you may have to restore as New and reconfigure from scratch as the backup could be corrupted. For this reason it is important to have your photos and data saved separately from the backup. Here are the steps for a Restore:

This has happened to me before as well.

Try reinstalling iOS, and if this does not work, your iPhone is defective.

After installing a new update, my iPhone 6's Touch ID stopped working, and I had to get a replacment.

Good luck.

I am having the same issue here aswell.

Tried re-installing the iOS from the beginning but still no luck and Touch ID is still not working.

Used to work perfectely with iOS 9.3

I have same issue on 5s, still not working after a System restore...

Same thing happened to me on my iPhone 6 Plus (don't know if it is 6 or 6S)  Tried all remedies mentioned but no luck - what next?

Same thing happened to my wife's 5s. Restarting and restoring didn't help.

I also have the same problem with my Iphone 6+ after upgraded to iOS 10 OTA. I tried to restart, hard reset... but nothing changed. I also downgraded to 9.3.5 then Touch ID worked smooth. When upgraded again by Itunes, i still got this problem.

Need some help!!!!

Same here. After upgrading to ios 10, touch id failed to activate. Tried to restore phone and restart but no luck. Touch id worked well when downgrading back to ios 9.3.5 and trying to upgrading again via itunes and touch id stopped working again.

I have similar issue as well. There are no problems on iOS 9.3.5. Downgrading fixes the problem.

I tried System Restore, DFU Restore none of them didn't help. Please fix this.

I upgrade my iPhone 5S to iOS 10 today.  The Touch ID was working fine in iOS 9.3.5 before upgrading.  After the upgrade I am getting "Unable to activate Touch ID on this iPhone.".  I've tried the hard reset, system restore, and setting the phone up as a new phone, all to no avail.  I have not tried downgrading yet.  I doubt that my Touch ID sensor spontaneously failed as a result of the upgrade, so this really seems like a software bug.

Same problem as everyone else! iPhone 6+ was updated to iOS 10 and Touch ID stopped working. I did everything mentioned (home button/sleep wake button restart; system restore), and the problem continues. It worked fine with the previous version of iOS.

Where are you Apple??? Respond to our queries and let us know you're working on a new update to fix the problem!!!

You might need to enter your passcode or Apple ID instead of using Touch ID for one of these reasons:

• If you've just restarted your device
• If your fingerprint isn't recognized five times in a row
• If you haven't unlocked your device in more than 48 hours

• If you've just enrolled or deleted fingerprints
• If you're trying to open Touch ID & Passcode in the Settings menu

If you still need help, follow these steps. Try using Touch ID after each step:

1. Make sure that you have the latest version of iOS.
2. Make sure that your fingers and the Home button are clean and dry.¹ For the Home button, use a clean, lint-free cloth to wipe off any dirt or debris.
3. Your finger should cover the Home button completely, touching the surrounding metal ring. While Touch ID is scanning, you shouldn't tap too quickly or move your finger around.
4. If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring.
5. Go to Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on, and 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 or Apple Authorized Service Provider, or contact Apple Support.

¹ Moisture, lotions, sweat, oils, cuts, or dry skin might affect fingerprint recognition. Certain activities can also temporarily affect fingerprint recognition, including exercising, showering, swimming, cooking, or other conditions or changes that affect your fingerprint.

charshaz,

Thank you but did you read what everyone has written?  It's not even giving us the opportunity to enroll our fingerprints on a phone that was working fine with iOS 9.3.5.  Before even going into settings, an error about not being able to activate Touch ID on the phone pops up.  What good is taking an out-of-warranty phone to an Apple Store or Apple Authorized Service Provider going to do to fix what appears to be a software bug other than cost us money?

The same happened to me, after update, Touch ID won't work on my 5s..no problems on my 6s...

I restored to factory settings, did a clean restore via iTunes, restarted...did everything! was perfect before the update.

what can be done?
