Today OnePlus has made available an update for Oxygen OS for its first smartphone OnePlus One. While the OnePlus 2 has launched running Oxygen OS outside of China, the situation’s been more complicated for its predecessor.
International One units shipped with Cyanogen OS on board, but since OnePlus and Cyanogen, Inc. aren’t getting along anymore the Chinese startup has outed a version of its own OS, Oxygen, for the One. This was a few months ago, and it hasn’t even been updated to Android 5.1 yet.
So What Is Stagefright ?
According to OnePlus “Stagefright” is basically a vulnerability in the multimedia stack that can be exploited via MMS which could compromise your phone. If you are currently using OxygenOS, Its highly recommended to upgrade to this new version. If you are already on OxygenOS, this update does not require a reset.
