Smart ,Simple and Truly yours

Android KitKat brings all of Android's most innovative, most beautiful, and most useful features to more devices everywhere.Its has more polished design ,improved performance and have many new features.

First Time ever Making Android for everyone

Android 4.4 is designed to run fast, smooth, and responsively on a much broader range of devices than ever before , including on millions of entry-level devices around the world that have as little as 512MB RAM. KitKat streamlines every major component to reduce memory use and introduces new APIs and tools to help you create innovative, responsive, memory-efficient applications.

Just say “Ok Google”

You don’t need to touch the screen to get things done. When on your home screen* or in Google Now, just say “Ok Google” to launch voice search, send a text, get directions or even play a song.

NFC capabilities through Host Card Emulation

It introduces new platform support for secure NFC(near field communication) -based transactions through Host Card Emulation (HCE), for payments, loyalty programs, card access, transit passes, and other custom services. With HCE, any app on an Android device can emulate an NFC smart card, letting users tap to initiate transactions with an app of their choice , no provisioned secure element (SE) in the device is needed. Apps can also use a new Reader Mode to act as readers for HCE cards and other NFC-based transactions.

Low Power Sensors

It introduces platform support for hardware sensor batching, a new optimization that can dramatically reduce power consumed by ongoing sensor activities.

With sensor batching, Android works with the device hardware to collect and deliver sensor events efficiently in batches, rather than individually as they are detected. This lets the device's application processor remain in a low-power idle state until batches are delivered. You can request batched events from any sensor using a standard event listener, and you can control the interval at which you receive batches. You can also request immediate delivery of events between batch cycles.

Step Detector and Step Counter

It also introduces the step detector and step counter sensors that counts and detect your steps while you are walking. The step detector analyses accelerometer input to recognize when the user has taken a step, then triggers an event with each step. The step counter tracks the total number of steps since the last device reboot and triggers an event with each change in the step count. Because the logic and sensor management is built into the platform and underlying hardware, you don't need to maintain your own detection algorithms in your app.

These sensors are available on Nexus 5.

 

A work of art

While listening to music on your device, or while projecting movies to Chromecast, you’ll see beautiful full-screen album and movie art when your device is locked. You can play, pause, or seek to a specific moment.

Just swipe the edge of the screen to bring back your status bar and navigation buttons.
