Android 4.2.2 adds some new eye candy, like allowing Instagram video to stream onto BlinkFeed. Thankfully, it also eliminates the black bar that marred some Android apps on the phone, and also adds a battery percentage indicator to the status bar. Daydreams adds colorful new animation to the lock screen, and a swipe up from the home page now launches Google Now. There are also some improvements made to the camera and to Zoe. The quick settings feature has been revised and HTC has added a way to share a screenshot, something most recent Android models already allowed. The app drawer and dock have been updated and widgets for the lock screen have been added. Sense also was tinkered with, although it still goes by the same Sense 5.0 title.
Since the update did go out OTA, it might take some time before you see it since the update is sent out in waves. You can try to pull it out of your phone by going to Settings > About > Software updates. The update weighs in at a hefty 471MB. As for when we might see this in the U.S., it is anyone's guess at this point. It is all about the carrier testing. The thing that apparently irks HTC One owners in the states the most is that the Samsung Galaxy S4, the handset that is the most direct rival to the HTC One in the country, launched with Android 4.2.2 installed out of the box. The Verizon version of the HTC One, expected to launch sometime this month, will probably come with the updated Android build already pre-installed.
