Over the past few weeks chatter about an upcoming Android update has significantly increased. The Android 4.4.3 update build numbers have already been spotted in bug reports and server logs, which may indicate that the update’s soak test has begun. Folks at AndroidPolice have heard from a “source familiar with the situation” that the Android 4.4.3 update isn’t going to be too spectacular. In fact, its expected to primarily fix bugs.
Since its believed to be an incremental update, its highly unlikely that Google will bundle any new features or major user interface changes with Android 4.4.3. However, it is expected to feature fixes for over two dozen bugs, so the least this update will do is make the user experience a bit better.
A complete list of fixes isn’t available as yet, we’ll have to wait on the official Android 4.4.3 changelog to be sure of what the update brings. Nevertheless, it is reportedly going to come with several connectivity fixes, such as data connection dropout, Wi-Fi auto-connect, data usage graph, internet telephony and multiple fixes for Bluetooth.
There is no word as yet about the expected release date of Android 4.4.3. Google hasn’t commented on rumors regarding this update, so its highly unlikely that it’ll even talk about the update before its actually ready for public release.
