Android 5.1 Lollipop made its way to HTC's One M9 flagship on AT&T and T-Mobile US in July, and continued its rollout earlier this month in Europe, the Middle East and Africa. Today, another US carrier will begin updating the device to the latest public release of Android.
HTC's Vice President for Product Management, Mo Versi, says that Android 5.1 will begin rolling out over-the-air today. Along with the standard roster of additions and tweaks that Google's 5.1 update brings, Verizon is also enabling roaming support for LTE Bands 3 and 7, which are widely used outside of the US.
More importantly, however, the update also includes a fix for the Stagefright vulnerability, a particularly serious flaw at the heart of the OS, which is believed to affect almost every Android handset currently in use. Google and its partners have been widely criticized for dragging their feet in ensuring that all devices are protected, although some - including Google itself - have recently committed to rolling out monthly security updates for their devices.
While Android 5.1 will begin making its way to Verizon's HTC One M9 later today, as with all such updates, it may take a little while before all eligible devices receive the update notification.
In the meantime, Google is continuing development work on the next major version of its OS, Android 6.0 Marshmallow, which should be released in a few weeks' time.
