Q: Deleted touch ID

Apple Team should address this issue. It happens to iPhone 5s, too. Downgrading to 9.3.5 will fix the problem.

Hi

Sounds like a hardware problem

Make an appointment at apple store or contact  support.apple.com

Cheers

It is not a hardware problem, it works like a charm on iOS 9.3.5. I restored iOS 10.0.1 and set up my device as 'a new iPhone', it does not help. I've just downgraded to iOS 9.3.5, it works like a charm again.

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

So, it is not a hardware issue, it is related to iOS 10.

Please file bug report to bugreport.apple.com

very funny..... you have to be a developer blalblabla..... guess this Limits the Messages there.

I've just filed a bug report without logs. I've downgraded my device to 9.3.5. If there are people who is on iOS 10.0.1, please take a look at Touch ID logging section and make a log of errors. Then, post it to bugreport.apple.com.
