The new version will have certain features made better to enhance the Android experience.
In the last a few weeks, expressions of an approaching Android 4.4.3 launch began spreading around, generally dependent upon sightings of new form numbers in server logs and bug reports. Obviously, with such a variety of 4.4.3 notice, its no astound that these are really real and not manifestations of irregular trolls.
As stated by a source acquainted with the circumstances, Android 4.4.3 is, unsurprisingly, going to be an immaculate bug-fixer release. We shouldn't be seeing new characteristics or UI changes - Google is sparing those for a more significant release (we should not estimate on 4.5, 5.0, and so forth - its far excessively early for that).
Rather, the Android 4.4.3 changelog is going to be embodied a few dozen fixes which are condensed underneath. Sad for the absence of accurate subtle elements for each change;one needs to sit tight for further releases or the authority release to AOSP so that everyone can run a diff (not like Google is going to organize each low-level change). A further consolation that this news is correct is that the source incorporates a screenshot of 4.4.3 running on a Nexus 5, with a few parts redacted.
