Apple has announced the release of an update to its previously announced iOS 9.2 upgrade. The update fixes some key bugs and certain issues related to iOS 9.2 that was launched last month by the Cupertino giant.

The update, iOS 9.2.1, is the fifth instalment for the iOS 9 series and has been preceded by iOS 9.0.1, iOS 9.0.2, iOS 9.1 and iOS 9.2. The new update does not come with any added features, and merely serves to rectify bugs and security gaps witnessed in the last major update. The latest beta version, iOS 9.2.1 is already out for developers, within a month of the launch of iOS 9.2.1 on December 16.

While the new update is intended to contain security updates and fixes for bugs, it does not rectify the battery indicator issue witnessed some time ago. Apple seems to have not found any resolution to this issue and might deal with the problem in the next big iOS 9.3 release.

The new update is available starting today, nearly a month after its beta version was tested out by few users. This update’s biggest fix is the issue that is preventing the completion of an app’s installation while using an MDM server.

Announcing the release, Apple stated

This update contains security updates and bug fixes including a fix for an issue that could prevent the completion of app installation when using an MDM (Mobile Device Management) server.

The MDM refers to the systems and devices, which are used by corporations to provide access of these devices to their employees.

It is also reported the next big update, which would be the first for this year by Apple is already being tested. iOS 9.3 is in the testing stage and developers are trying their hand at the future iOS update. iOS 9.3 is pitted to be a major update with some new features being introduced into it. Features such as Quick Actions intended for iPhone 6S and iPhone 6S Plus, and Night Shift option, password protection for Notes among others are expected to be part of this update.

Apple has also hinted through its latest iOS versions that it might be testing the implementation of Li-Fi wireless network on its devices. A few of iOS updates in the past one year contain references to Li-Fi, which is still in its experimental stages. Li-Fi is expected to replace the existing Wi-Fi connections as it is faster and relies on pulses of light to transmit data.

The first reference to Li-Fi was seen in iOS 9.1, where a cache file indicates the ability to connect to a Li-Fi network.
