Tech giant Apple Inc. has released a patch Friday to fix issues on a version of the iOS 8 mobile operating system after approximately 40,000 users had their Touch ID disabled and lost phone service.

Currently available to be downloaded on iTunes, the iOS 8.0.2 improves on the defective iOS 8.0.1, which was discovered on Thursday after the first update was made accessible to the public. Apple then allowed users to revert to the original version of the iOS 8 OS.

After users installed the 8.0.1 update, the handsets showed a "no service" box which persisted even after the devices were shut down and restarted.

The Cupertino-based company, which promised an update within a "few days," actually released the 8.0.2 after 24 hours. Apple clarified the situation on its support page.

"iOS 8.0.2 is available now. It fixes the loss of cellular service and use of Touch ID that may have affected you if you have an iPhone 6 or iPhone 6 Plus and you downloaded iOS 8.0.1," Apple wrote. "It includes improvements and bug fixes originally in iOS 8.0.1. We apologize for inconveniencing you if you were affected by the bug in iOS 8.0.1."

Various Apple blogs have reported that users were being notified regarding the upgrade on Friday and could go into the smartphone's Settings menu to install the new software update.

Apple said that bug in iOS 8.0.1 only hit the iPhone 6 and 6 Plus and did not affect the older versions of iPhones, such as the  4S, 5, 5S and 5C.

Meanwhile, Apple is also addressing another bug, but on a different operating system.

Apple Inc. has issued a public statement the same day it released the iOS 8.0.2 in response to the Bash bug, assuring consumers using the OS X operating system that they're mostly safe from potential cyber attacks.

A spokesperson from the tech company said that most users that use their operating system are safe from the exploit.

The spokesperson added that in the company's OS, systems are safe by default and are not exposed to being exploited remotely with the shell unless users have altered the advanced settings of UNIX services.
