Apple has stopped providing an update to its new iOS 8 mobile operating software, following complaints that the update interferes with users' ability to make phone calls.
The iOS 8.0.1 update released Wednesday morning was intended to fix some earlier glitches in the new software for iPhones and iPads that Apple released last week.
But along with blocking calls, some users have also complained the update interferes with Apple's Touch ID system, which lets people unlock their phones with their fingerprint.
Apple says it's pulling back the update as it investigates the reports. The company says it plans to issue advice to users "as quickly as we can."
Meantime, users are still able to the upgrade older phones to last week's version of iOS 8.
