Have you been experiencing any bugs since updating your Nexus device to Android 4.4.3?
On the whole, Android 4.4.3 was meant to fix a bunch of bugs, most notably the battery drain which was tied to the camera software. There were also fixes put in place to stabilize network connectivity and notifications.
SMS and MMS through Hangouts needed some work too, along with making support for Exchange Active Sync more reliable was part of the repertoire too. The dialer in Android 4.4.3 is refreshed as well. All-in-all, things are looking fairly solid, but some new bugs seem to be emerging from the bugs that were squashed.
On Nexus 4 and Nexus 5 devices, it appears that some units are experiencing trouble with Wi-Fi connectivity. For Nexus 4 devices, it appears some that were having random reboot issues under Android 4.4.2 continue to experience the same after the update to 4.4.3.
Some Nexus 5 owners appear to notice new lag when selecting the “all contacts” option from the new dialer. There has been no official word from Google, but it is certain that the gang in Mountain View knows about the deal.
How about you? Did you update your Nexus device to Android 4.4.3? How is everything running?
