Sprint has announced that an over-the-air software update is due out for its version of the Galaxy S4 going by the name of version number L720VPUFNG2. The changelog for this one is pretty minor, so there's little reason to start abusing that update button. Galaxy S4 owners should be on the lookout for an HD Voice icon (which they might be able to notice), and a number of security patches (which they won't).
Update, 7-25-14: It looks like this over-the-air update was delayed for some reason. Samsung says it's coming in now.
KitKat is making its way to the Galaxy Note II. We've seen it come to Sprint, and just yesterday it started rolling out to Verizon's version of the handset. Now US Cellular has updated the support page for its Note II to say that KitKat is on its way.
One of the features LG pushed hard with the announcement of the G3 was its Knock Code screen locking feature. While the device is asleep, you can tap on the screen in predefined locations to wake it and unlock instantly. Knock Code actually debuted on the G Pro 2, but now Sprint's G2 is getting it as well.
Sony has announced an impending software update for the Xperia T2 Ultra and the T2 Ultra Dual that will deliver Android 4.4 to both devices. The update contains the changes introduced by KitKat, but it also tosses in a number of Sony-exclusive touches.
Sony's designers have tweaked the status bar and quick settings to make them easier on the eyes, and they've tossed in new animations at launch and on the homescreen that may look familiar to PlayStation 4 owners.
A minor OTA update is now rolling out to the small population of people who happen to own Google Glass. This release, XE19.1, brings improved network connectivity, so Glass should now do a better job of handling spotty network issues when issuing voice commands. This is good considering how much Google's voice search relies on the web.
XE19.1 also brings in a slight visual revamp, as Glass now has a cleaner look for voice actions.
The first Android Wear devices are just starting to show up on doorsteps, but already a second update is heading out to the Samsung Gear Live. The OTA bumps the build to KMV78X from KMV78V. What does it do? Unclear.
