Over the weekend i have received a number of calls regarding touch sensitivity issues , hanging , fingerprint unable to unlock iPhone and frozen iPad  .

and when i saw this news today , it clearly explains that iOS 9 should be the caused off all this.

my advise to all is to back up your iPhone/ data / memories with iTunes / iCloud  while we wait for a solution from apple .

Apple’s release of iOS 9.1 may have introduced a Touch ID problem for some iPhone and iPad users, reports Forbes. The site took notice of numerous support threads (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) on Apple’s Support Communities complaining of problems with fingerprint recognition.

The complaints are similar: users running iOS 9.1 find Touch ID either refuses to recognise a user’s fingerprint, has become highly unreliable or doesn’t even register a fingerprint pressed against it. Users have tried hard resets (holding in the power and home button for 10 seconds) and complete factory resets without any success.

Notably, Forbes spent a few days discussing the problem with Apple before going to print; however, the company’s official statement on the matter is: “No comment”.

As Apple is aware of the reports, presumably it is working to identify and rectify the problem. Unfortunately, the signing window for iOS 9.0.2 has been closed and you can’t downgrade from iOS 9.1.
