Google launches new version of operating system KitKat, compatible with all versions of Android.

Google released the latest version of its Android 4.4 operating system, code-named "KitKat," on Thursday, aiming to bring more smartphone users into contact with the company's ever-evolving menu of web services, such as voice-controlled navigation and search services.

Sundar Pichai, Google's Senior Vice President of Android, Chrome, and Applications, stated at a press conference in San Francisco that day that the latest Android 4.4 KitKat operating system can run on both affordable, low-end smartphones and the most advanced devices. Pichai said, "Now you will have an operating system that runs across all versions of Android smartphones." He also emphasized that smartphones sold to emerging markets typically come with older versions of Android, which lack many key features.

The launch of KitKat could help Google bring more users into its profitable web services. This move could also make the Android operating system more attractive to third-party app developers. Previously, the "fragmented" nature of Android devices had discouraged some third-party app developers.

Industry analysts estimate that Google's Android operating system is now running on approximately 80% of the world's smartphones. However, a large number of Android devices still use older versions of the operating system, which are incompatible with many new features. Analyst Colin Gillis of BGC Partners stated that a significant number of app developers still prioritize developing apps for Apple's iPhone and iPad first. He said, "Google wants users to use their services, and KitKat can help achieve this goal."

Data released on October 2 showed that about 29% of Android smartphones worldwide are still using the "Gingerbread" operating system, which was launched in December 2010. It uses an older version of the browser and does not support the Google Now voice assistant feature.

KitKat integrates Google's search technology directly into the phone in various ways. The phone's contact list allows users to look up acquaintances' phone numbers as well as information about local businesses like restaurants and dry cleaners. Google also showcased some of KitKat's new features, such as enabling smartphone users to search via the web and installed apps within the phone for relevant information. For instance, when searching for chocolate cookie recipes, the results may include those from a cooking app on the phone.

Google also unveiled the first smartphone to feature the KitKat operating system, the Nexus 5, on Thursday. Produced by LG Electronics, the device will go on sale in ten countries worldwide starting Thursday, priced at $349.
