Mobile operating system

Small tools use special software.

This software runs your phone. It also runs tablets and smartwatches. It helps these tools work.

The software lets you talk to friends. It uses a built-in part to connect to data. This helps you use the web.

Many people use these tools every day. In 2024, many new phones were sold. One kind of software is very popular. It is used on more phones than other kinds.

These tools are very helpful for us. They let us stay connected to the world.

A mobile operating system is special software. It runs devices like smartphones and tablets. It also runs smartwatches and smartglasses.

These systems are different from laptop software. Laptops were made for desktop use. Mobile systems have extra parts. They include a built-in modem. This modem helps the device connect to data and phones.

Most smartphones use two systems at once. One part is the main software you see. A second, low-level system is also there. This second system is called a real-time operating system. It helps run the radio and other hardware. Some studies show these low-level systems can have security gaps. This might let bad actors gain control of a device.

Many people use these systems every day. In 2024, about 1.22 billion smartphones were sold. This was a 7% increase from the year before. Android is a very popular system. In 2023, it made up 53.32% of sales. Android has more sales than Microsoft Windows on desktops. Mobile systems are used more than desktop systems now.

A mobile operating system is the main software that runs handheld devices. This includes smartphones, tablets, smartwatches, and smartglasses.

While laptops are also mobile, their software is usually not called a mobile operating system. Desktop software was originally made for computers that did not need mobile features. Today, the line between these systems is getting blurry. This is because new devices like 2-in-1 PCs and light laptops are becoming more portable.

These systems work by combining desktop features with tools for handheld use. They usually include a built-in wireless modem. This allows the device to connect to data and phone networks using a SIM tray. Most smartphones actually use two different systems at the same time. The first is the main platform that you see and touch. The second is a low-level, proprietary real-time operating system. This second system manages the radio and other hardware parts. Research shows these low-level systems can have security vulnerabilities. These gaps might let malicious base stations gain control over a device.

Mobile software has a long history of many changes. Before 1990, mobile phones used simple embedded systems to work. In the 1990s, new systems like Apple's Newton OS and Palm OS appeared. The IBM Simon was the first smartphone, featuring a touchscreen and email. In 1998, a group of companies formed Symbian Ltd. to create the Symbian OS. This system was used by many big brands, especially Nokia. By the early 2000s, BlackBerry released its first smartphone using Java. This era saw many different ways to manage mobile tasks.

Recent years have shown how huge this industry has become. In 2024, about 1.22 billion smartphones were sold around the world. This was a 7% increase from the year before. In 2023, there were 1.43 billion sales in total. Android was the leader in 2023 with 53.32% of those sales. Android actually has more sales than the Microsoft Windows desktop system. Since 2017, mobile operating systems have seen the most use of any system. This is even measured by how much people use the web.

You can see how these systems connect to your daily life. Many people use tablets or smartphones every single day. For example, Apple released the iPad in 2010 with iPhone OS. This was the first version to support tablet computers. Later, the software was renamed to iOS. Other companies like Google led the Open Handset Alliance to grow Android. These different paths show how technology moves from simple phones to powerful tools. Every device you hold uses these smart systems to function.

A mobile operating system is the primary software that manages personal computing devices designed for portability. This category includes smartphones, tablets, smartwatches, and smartglasses.

While laptops are mobile in a physical sense, their software is usually not classified as a mobile operating system. This is because desktop systems were originally designed for computers that lacked specific mobile requirements. In recent years, the distinction has become blurred. The rise of tablets, lightweight laptops, and 2-in-1 hybrid PCs has merged these categories.

These systems function by merging desktop-style capabilities with features optimized for handheld use. Most mobile operating systems include a built-in wireless modem and a SIM tray. This hardware allows the device to maintain telephone and data connections. Interestingly, a single smartphone often runs two distinct operating systems simultaneously. The first is the user-facing platform that provides the interface. The second is a low-level, proprietary real-time operating system, or RTOS. This RTOS manages the radio and other essential hardware components. Research indicates that these low-level systems may contain security vulnerabilities. These gaps could potentially allow malicious base stations to gain high levels of control over a device.

The history of mobile software mirrors the evolution of mobile hardware. Before 1990, mobile phones relied on simple embedded systems to function. The 1990s introduced more complex platforms like Apple's Newton OS and the Palm OS. A major milestone occurred in 1994 with the IBM Simon, the first smartphone. It featured a touchscreen, email capabilities, and PDA features. In 1996, the Palm Pilot 1000 introduced the Palm OS. Later, the Nokia 9000 Communicator used a system based on the PEN/GEOS 3.0 OS. By 1998, Symbian Ltd. was formed as a joint venture between Psion, Ericsson, Motorola, and Nokia. This led to the development of the Symbian OS, which became a dominant force in the industry.

As the 2000s progressed, the market saw rapid innovation and competition. BlackBerry released its first smartphone in 2002 using Java 2 Micro Edition. During this same period, Microsoft introduced Windows CE for Pocket PC devices. Nokia's Symbian Series 60 became a foundation for many smartphones. This platform powered devices like the Nokia 7650, which included a camera and MMS capabilities. In 2007, Apple changed the landscape by introducing the iPhone. Initially called iPhone OS, it functioned as a widescreen iPod and Internet communicator. Shortly after, the Open Handset Alliance was established in 2007. Led by Google, this group included members like Samsung, HTC, and Motorola to develop Android.

The 2010s marked a period of significant shifts in dominance and platform types. Apple released the iPad in 2010, which was the first version of iPhone OS to support tablets. Following this, the software was renamed to iOS. Android also expanded its reach, with version 3.0, known as Honeycomb, released in 2011 to support tablets. Other players entered the field, such as BlackBerry with its Tablet OS and Mozilla with Firefox OS. However, many platforms faced discontinuation. For example, HP halted development of webOS in 2012. Nokia eventually abandoned the Symbian OS in 2011 to adopt Microsoft's Windows Phone 7 platform.

Today, the scale of mobile operating system usage is immense. In 2024, approximately 1.22 billion smartphones were sold globally. This represents a 7% increase compared to the previous year. This growth follows two consecutive years of declining sales. In 2023, total smartphone sales reached 1.43 billion units. Android held a massive market share, accounting for 53.32% of those sales. In fact, Android has more sales than the Microsoft Windows desktop operating system. Since 2017, mobile operating systems have seen more use than any other type of system. This trend is even evident when measuring global web usage.

Understanding mobile operating systems requires seeing them as part of a larger technological ecosystem. They connect hardware, wireless communication, and user software into a single experience. The transition from simple embedded systems to complex, multi-layered platforms shows how computing has become more integrated. These systems allow for constant connectivity through cellular networks and data services. As hardware continues to shrink and become more powerful, the lines between mobile and desktop computing will likely continue to fade. This evolution drives how we interact with the digital world every day.
