HTC One M8 owners on the Sprint network can now download a system update which patches the Stagefright vulnerability in Android. The 4.25.651.18 system update for the Sprint HTC One M8 is being pushed out to device automatically, but you can manually trigger the update by going to Settings > System updates > HTC software update > Check now.
HTC is working as quickly as it can to release the Stagefright patch to as many phones as possible in an effort to keep its users and their data secure from potential hackers. Expect to see quite a few Stagefright patch updates for HTC phones over the next few weeks and months.
