1. Android OS

Android is a mobile operating system (OS) currently developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. It has been the best-selling OS on tablets and on smartphones since 2013

Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. The operating system's current design language is Google's Material Design. Android's primary app store is Google Play, with over one million Android applications ("apps") published and 50 billion downloads as of July 2013. In addition to touchscreen devices, Google has further developed Android for television, cars, and wristwatches, each with a specialized yet similar interface. Variants and forked versions of Android are also used on notebooks, game consoles, digital cameras, and other electronics.

2. Blackberry OS

BlackBerry OS is a proprietary mobile operating system developed by BlackBerry Ltd for its BlackBerry line of smartphone handheld devices. The operating system provides multitasking and supports specialized input devices that have been adopted by BlackBerry Ltd. for use in its handhelds, particularly the trackwheel, trackball, and most recently, the trackpad and touchscreen.

The BlackBerry platform is perhaps best known for its native support for corporate email, through MIDP 1.0 and, more recently, a subset of MIDP 2.0, which allows complete wireless activation and synchronization with Microsoft Exchange, Lotus Domino, or Novell GroupWise email, calendar, tasks, notes, and contacts, when used with BlackBerry Enterprise Server. The operating system also supports WAP 1.2.

Updates to the operating system may be automatically available from wireless carriers that support the BlackBerry over the air software loading (OTASL) service.

Third-party developers can write software using the available BlackBerry API classes, although applications that make use of certain functionality must be digitally signed.

3. iOS

First iteration of Apple's touch-centric mobile operating system.

Apple's iOS did not have an official name until the release of the iPhone software development kit (iPhone SDK) on March 6, 2008. Before then, Apple marketing literature simply stated that their iPhone runs a version of OS X, a reference to iOS' parent operating system. When introduced, it was named iPhone OS. It was renamed iOS on June 7, 2010, as, with the introduction of the iPad, and the existence of the iPod Touch, the iPhone was no longer the only device to run the mobile operating system. iOS 4 was the first major release to reflect this change. Apple licensed the "iOS" trademark from Cisco Systems.

4. Symbian OS 

Symbian was a mobile operating system (OS) and computing platform designed for smartphones. Symbian was originally developed as a closed-source OS for PDAs in 1998 by Symbian Ltd. As a pioneer that established the smartphone industry, it was the most popular smartphone OS on a worldwide average until the end of 2010 – at a time when smartphones were in limited use, when it was overtaken by Android.

Symbian OS was (from 2001) essentially a shell system and required an additional user interface (as middleware) to form a complete operating system. Symbian OS became prominent from the S60 (formerly Series 60) platform built by Nokia, first released in 2002 and powering most Nokia smartphones. Symbian eventually became the most widely used smart mobile operating system. 

Nokia was the majority shareholder in Symbian Ltd. and purchased the entire share in 2008.

5. Window Mobile OS

Windows Phone (WP) is a family of mobile operating systems developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone features a new user interface derived from Metro design language. Unlike Windows Mobile, it is primarily aimed at the consumer market rather than the enterprise market.[8] It was first launched in October 2010 with Windows Phone 7. Windows Phone 8.1 was the last public release of the operating system, released to manufacturing on April 14, 2014. Windows Phone has been succeeded by Windows 10 Mobile, with the Windows Phone name being phased out in favor of branding the platform as an edition of Windows 10.
