Chinese mobile startup OnePlus, which recently launched its second smartphone and expects to sell a million of them in India alone this year, announced a new update on the software front Friday.

Before the launch of the OnePlus 2 handset, the company had made it official that it would henceforth be shipping its own user interface software, called OxygenOS, after it decided to discontinue the use of CyanogenMod software, with which the OnePlus One had been initially launched.

The company has rolled out the latest version of OxygenOS, version 2.0.1, which users can install on their phones over-the-air, OnePlus said in a post on its website Friday. Such user interface software, or "skins" as they are commonly called, are developed by smartphone vendors to differentiate their handsets from that of competitors. They run on top of the "stock" or "pure" Android operating system that Google Inc. builds and distributes in an open-source model.

The OnePlus 2 smartphone's OxygenOS runs on top of the Lollipop version of Android.

“This OTA will be rolling out incrementally, starting in India, so it may take some time before the update reaches all OnePlus 2 devices,” OnePlus said in the post.

An important part of the latest version is that it comes with a patch for the so-called Stagefright security exploit in the Android operating system. It refers to flaws in a bunch of code called libStageFright in Android used to process video that could theoretically be exploited using maliciously packaged MMS messages, AndroidCentral said in a post.

Other improvements and fixes in the version 2.0.1 relate to battery performance, user interface, an issue with pinch-to-zoom in Google Photos, a glitch where Dark Mode would cause instability in certain apps, a problem related to import/export of contacts stored on SIM cards, OnePlus said.
