Android KitKat
Android KitKat also known as Android 4.4, was the fourth major version of the Android operating system, released by Google. It brought several improvements, optimizations, and new features to the Android platform. Android KitKat was officially announced in September 2013 and was first released in October 2013. Here are some key features and changes introduced in Android KitKat:

2. Immersive Mode: KitKat introduced “Immersive Mode,” which allowed apps to make use of the entire screen for a more immersive experience, hiding the status and navigation bars until the user interacted with the screen.
3. Enhanced Dialer and Caller ID: The dialer app received an upgrade with improved caller ID that could identify businesses and provide relevant information from Google Maps and Google Search.
4. SMS Integration: KitKat introduced Hangouts as the default SMS app, integrating SMS and instant messaging into one application. This feature aimed to simplify messaging and communication for users.
5. Cloud Printing: Android KitKat added support for cloud printing, allowing users to print documents and files directly from their Android devices to compatible printers connected to Google Cloud Print.
6. Enhanced NFC Support: KitKat improved support for Near Field Communication (NFC), making it easier for users to make payments and exchange data with NFC-enabled devices.
7. New “OK Google” Command: KitKat introduced the “OK Google” voice command that allowed users to perform Google searches, set reminders, and launch apps using voice commands.
8. Emojis: KitKat included a more extensive set of emojis and a redesigned emoji keyboard for users to express themselves in messages and social media.
9. Screen Recording: Android KitKat introduced the ability to record the screen directly from the device, which was a useful feature for creating tutorials, demonstrations, or sharing gameplay.
10. Print Preview and Wireless Printing: The platform added print preview capabilities and the ability to print documents over Wi-Fi or using cloud print services.
11. Lower Audio Latency: KitKat reduced audio input and output latency, making it more suitable for audio applications, music production, and gaming.
12. Closed Captioning: Closed captioning support was improved in KitKat, making it easier for users with hearing impairments to access content with subtitles.
13. Security Enhancements: KitKat included various security enhancements, such as improved app sandboxing and the “Verify Apps” feature to protect against potentially harmful apps.
14. Support for 64-bit Processors: KitKat introduced support for 64-bit processors, preparing the Android ecosystem for the transition to more powerful hardware.
