Error 53: A mysterious Apple bug is killing iPhones worldwide

Users worldwide are reporting a mysterious Error 53 that is rendering their iPhones useless. The error seems to be affecting iPhones that have suffered damages and in cases where users have got them repaired from third-party service centers, especially repairs that involve replacing the home button that also has the Touch ID fingerprint sensor or replacing the display. The error seems to be affecting only iPhone 6 and iPhone 6 Plus users at the moment though the jury is still out. Users who have experienced Error 53 claim that their iPhones worked properly after the repair was done but got bricked with Error 53 only after they updated their device to the latest iOS version, the Guardian reports.
