HTC clearly understands that waiting for an update for your phone can be frustrating. The company has taken to their official site that contains two pretty awesome things. One being a detailed status on the HTC One's 4.4 update, and another being a massive graphic detailing the upgrade process for the carrier branded, unlocked, and Google Play editions of the HTC One. It takes us through every step of the process, and what is arguably the most important part: that HTC isn't always at fault for the upgrades not appearing in a timely matter (or at all.) Chipset manufacturers and carriers are also large parts of the update process.
Check out the graphic "Anatomy of an Android OS Update" at HTC's official site.
