How to fix Faulty Touch ID on iPads Running IOS 17.5.1?

Have 2 iPads and suddenly both TOUCH ID options have become faulty in as much as when logging on they only work intermittently but once in they seem to be opening apps OK. One is a 2nd gen 12.9” iPad Pro and the newer one is iPad Air 3rd gen and both running on IOS 17.5.1. This has only just started happening about 3 to 4 weeks ago. I have reset finger Touch ID on both and followed instructions put out by apple support but the problem still remains. This is definitely not a fault with both iPads but a hardware problem that needs to be fixed. Neither iPads have screen savers or covers. Has anyone got any info on it please because I am going to get a new 2024 one soon but certainly not until this problem is rectified.

The causes for of TouchID being unreliable for some users - and not others - are many. Whilst not an exhaustive list, possibilities include:


  • Very high humidity (“sweaty” fingers)
  • Very low humidity (excessively dry skin)
  • Poor fingerprint ridge-detail (excessive hand washing - or exposure to abrasive material, damaging fingerprint detail)
  • Physical injury (cuts or splits to the fingertip)


If you have naturally dry skin, try using a “light” (non greasy) and easily absorbed skin moisturiser.


Note that the TouchID sensor is electro-optical - and has a metal ring around its periphery. Your finger must be in contact with both the ring and the sensor's optical surface.
