Google may have promised to keep its Nexus devices updated once a month, and was one of the first to push fixes for the vulnerability in Stagefright, but that doesn't mean owners of other phones will see such prompt updates. Today, weeks since Nexus devices were patched, AT&T's HTC One M9 and M8 are receiving over-the-air updates to keep you safe when sending MMS messages.

You can find information about both the HTC One M9 update and that for the HTC One M8 over at AT&T's website. The OTA for the M9 comes in at just 55.53 MB, while the M8 update is 28 MB. These are pretty tiny numbers for OTA updates, so you shouldn't expect much more from this update than the patch for Stagefright. It goes without saying that it's still important to update though.

Head over to the Settings app and mash that refresh button, or just wait until your device tells you that you're ready to go.
