HTC's software versioning is a little more complicated than it is with other Android OEMs. You might have Android 4.4.2, but be lacking many of the features found on a newer device because you have an older version of Sense. HTC can, and does, update these independently. Such is the case with last year's HTC One – some versions of the M7 are getting Sense 6 today to go with their KitKat ROMs.
If you happen to own an Atrix HD from AT&T, get ready for something you haven't seen in a very long time: a firmware update. Unfortunately, this is only a "security enhancement" and not an upgrade to the Android operating system. Motorola hasn't specified exactly what this update is supposed to fix, but it's almost certainly a patch for the Heartbleed bug that was widely reported last month.
The last update to the Atrix HD shipped out at the end of 2012, which brought it from 4.0.4 (Ice Cream Sandwich) to 4.1.1 (Jelly Bean).
If you've bought a DROID phone from Verizon and Motorola at some point in the last two generations, you've got an update coming soon. The carrier posted update materials for all 2012 and 2013 Motorola DROIDs: RAZR M, RAZR HD, RAZR MAXX HD, Mini, Ultra, and Maxx. The older phones are getting upgraded to Android 4.4.2, while the newer DROIDs just get a stability update.
Both Sprint and T-Mobile announced OTA updates for two long-forgotten handsets today stuck on Android 4.1.1 - the Samsung Nexus S and the HTC One S, respectively (that is, the Sprint Nexus S and the T-Mobile One S).
Both updates are described merely as containing security enhancements, but given that Android 4.1.1 is the only known OS version potentially vulnerable to the now-infamous heartbleed exploit, it's fairly easy to determine what this is all about (HTC's site actually confirms as much).
Remember the HTC EVO LTE? Sprint does, at least to some degree. The carrier is sending out a small software patch for the phone, reportedly removing a vulnerability from the infamous Heartbleed SSL security bug. Unpatched versions of Android 4.1.1 (and only 4.1.1) are vulnerable to Heartbleed, so EVO LTE owners probably want to get on that right away.
Heartbleed's relationship to Android is a little strange: it affects Android 4.1.1, but not earlier versions of Jelly Bean 4.1, and not later versions of any release, either, so the number of active phones and tablets at risk is comparatively small.
The last update to NVIDIA's Android-powered SHIELD game machine was only a month ago, but there's another one waiting in the wings. Since SHIELD is already running the latest version of Android, this is a maintenance update, but NVIDIA seems to be sending the full software image (460 megabytes) anyway. SHIELD users should see it pop up on their screens sometime today - make sure you're near a speedy WiFi access point before you begin.
Qualcomm released a substantial update to its Toq smartwatch today, taking advantage of a hardware feature few even knew the device had: a microphone. The 1.5 software adds the ability to respond to SMS messages on your phone through the watch using your voice, which is then converted to text using Nuance's STT technology. Oddly, no other voice control features are included with this update, though arguably the ability to reply to texts is one of the more common things you'd do with a smartwatch to begin with.
Verizon is not known for being liberal with the OTAs, but Galaxy S4 owners have been on the verge of revolt waiting on this one. Now, the KitKat update is finally heading out to the Samsung Galaxy S4. Users all over the country are reporting it is available for download, so begin mashing the update button.
The Droid DNA was the last device of its generation before HTC shook things up with the One (M7) in 2013. Also known as the Butterfly, the DNA launched with Android 4.1 and was later updated to 4.2. Owners have been clamoring for a taste of that sweet KitKat, and now it's almost here – HTC is starting the OTA push on April 24th.
