AT&T HTC One (M8) Update to Android 4.4.3 Rolling Out Now

Not-so-hot on the heels of the firmware rollouts to T-Mobile and Sprint HTC One (M8) variants earlier summer, the AT&T-branded model is finally receiving OTA love in the form of an update to Android 4.4.3, plus an additional few application updates and optimizations.

The changelog isn’t too exciting, unfortunately, unless “security fixes” really float your boat.

Still, who can say no to free updates? 


  • Android 4.4.3
  • Security fixes
  • Wi-Fi fixes
  • Bluetooth fixes
  • Mobile network fixes
  • Camera app update
  • Gallery (Image Match)
  • Settings (Power History)
  • HTC Sync Manager
  • Boomsound optimization
  • Extreme Power Saving Mode optimization
  • Motion Launch optimization
  • Quick Setting optimization

With the AT&T M8 fully up to date, that leaves the Verizon version. Sadly, Big Red subscribers won’t get their fix until mid-September – an earlier release was delayed for unspecified reasons.

    What is the status of the U.S. Cellular and CSprire M8 updates?

  • T. M.

    It’s already used 50% of my battery in the 3 hours since I updated

  • adbFreedom

    I would say no to this update because it will probably break the weaksauce exploit for root :/

      I just rooted my AT&T M8 after doing the update. To update, I did this-

      1. Flashed stock recovery
      2. Did the OTA Update
      3. Flashed TWRP
      4. Rooted

    Hey look! A camera update too! Might make the camera better cause we all know its all about settings and software, not the actual camera hardware /s

    Is it September for Verizon? I tweeted Jason Mackenzie and he told me it was going to be Mid/End of August, but got pushed back slightly

    Verizon’s Update was delayed because they realized they wouldn’t be last.. Now that AT&T has pushed out the update, Verizon can go ahead and release it themselves.

    Less than 90 days after 4.4.3 was released. Not ideal, but an improvement. Or maybe it’s just because I left Verizon. 🙂

      Verizon is still #1 in slowest updates. They are the king.
