That’s right, Android’s version number ticked up a tiny, tiny bit yesterday as pushed out Android 4.4.3 for the Android Open-Source oject (AOS as well as factory images for a whole bunch of Nexus devices. It looks like the last two Nexus 7 models, the Nexus 10, the Nexus 4 5 are all supported.  If you own one of those devices, you can break out ADB flash it yourself. Or you can wait for an over-the-air update from your carrier, which shouldn’t take too long. So is Android 4.4.3 (still called KitKat) worth fretting over? Should you count the days until your non-Nexus device gets an update? obably not. So far, it looks like it’s primarily a maintenance release full of minor bug fixes cleanup. Users have noticed two front-facing changes so far: refreshed Dialer ople apps. If you’re not using a Nexus phone, odds are you’re using a custom ROM that has its own phone dialer people/contacts app anyway. It’s great to see cleaning polishing like this, but we expect much bigger things from I/O in a few weeks.
