Android 4.4 KitKat review

Google introduced latest version of  mobile OS  "Android 4.4 KitKat".
Everyone was expecting Key Lime Pie to serve as the delicious moniker for the next version of Android. Google surprised us all by bucking tradition and releasing Android 4.4 under the name KitKat.
Version 4.0 started life as Ice Cream Sandwich, but the last three decimal additions came under the Jelly Bean banner. This new version was obviously deemed different enough to snag a new nickname, but not different enough to merit a jump to version 5.0.
That 0.1 bump hardly does it justice. Don't be fooled: this is an important step up for Android. KitKat is super-smooth, the UI is refined and elegant, there are improvements to the long-neglected calling and messaging side of the platform, a new focus on productivity, and your fortune-telling digital assistant is brought front and centre as Google Now reaches maturity.

General surprise in the tech world wasn't just based on the erroneous supposition that Key Lime Pie had to be next; there were also some raised eyebrows at the idea of Google entering into a tawdry cross-licensing deal with Nestle which would see a flood of Android-shaped KitKats hitting the shops offering buyers the chance to win Nexus 7 tablets or Google Play credit.
According to Google the promotion was its idea, and no money changed hands. With Nestle producing 50 million Android KitKat bars it certainly looks like a sweet deal for them.
Naming conventions aside, the 4.4 update is about addressing some of the Android criticisms that simply won't go away, and it does so very well indeed.
