The vulnerabilities, which are similar in severity to the Stagefright family of bugs disclosed last year, have been fixed in updates Google began distributing Tuesday. A large percentage of Android phones, however, aren't eligible to receive the fixes. Even those that do qualify don't receive them immediately (the September updates are currently not available as over-the-air downloads for either of the Nexus 5X devices in my household). That gives attackers crude blueprints for exploiting vulnerabilities that remain unpatched on millions of devices.

"The provided exploit performs this on several recent Android versions for the Nexus 5x and is both reliable and fast in my testing," he wrote in a blog post published Wednesday. "It would also be possible to make the exploit faster by directly generating the exploit files in javascript, reducing the unnecessary network round-trips [spent] retrieving identical mp4 files."
This. A 2 year old android phone is so much more outdated (especially in terms of security) than an iPhone
A 5-year-old iPhone 4S is more up to date and secure than most Android phones. The 5 is even getting iOS 10, and could get 11 as well considering the 4S stayed an extra version and 10 runs well on it.
