Some owners of the iPhone which have had repairs to their TouchID sensor by unofficial repairers have been getting an ‘Error 53’ message on their handset when they update their device to iOS 9 or above.
Apple has now confirmed the issue and explained that it is related to Touch ID on the handsets, when an unofficial part has been used for the home button.
You can see a statement from Apple below on the Error 53 issue on the iPhone that was given to Apple Insider.
“We take customer security very seriously and Error 53 is the result of security checks designed to protect our customers,” the company said. “iOS checks that the Touch ID sensor in your iPhone or iPad correctly matches your device’s other components. If iOS finds a mismatch, the check fails and Touch ID, including for Apple Pay use, is disabled. This security measure is necessary to protect your device and prevent a fraudulent Touch ID sensor from being used. If a customer encounters Error 53, we encourage them to contact Apple Support.”
So it looks like Apple has extra security built into their iPhones relating to Touch ID and the fingerprint sensor, considering the fingerprint sensor is used for Apple Pay and also purchases on Apple’s online store, it is hardly surprising.
If you have had this issue with you handset, then you should contact Apple to get the issue resolved.
