Android has become the most susceptible OS to malware because of its open-source platform, the readiness of Android devices to download and install applications from untrusted/unsecured stores. Unlike Android OS, Apple iOS is more immune against malware owing to its closed-source platform and the restricted procedures that Apple follows in apps marketing. We choose to talk about only the two most dominant phone OSs here: Android and iOS. Net framework, which gives it an advantage in developing. Windows phone OS is based on a compact version of. Windows phone OS is a closed-source code mobile OS developed by Microsoft Corporation and used by multiple smart devices (personal digital assistants, smartphones, and touch devices). Symbian was the most prevalent mobile device OS until 2010, when it was taken over by Android. Symbian OS consists of multiple layers such as OS libraries, application engines, MKV, servers, Base-kernel, and hardware interface layer. in 1977 it is mostly used by Nokia phones. Symbian OS is an open-source mobile OS written in C++ programming language developed by Symbian Ltd. The third layer is the core OS, which provides core services such as low-level data types, start-up services, network connection, and access. The second layer is the media layer, which provides audio services, animation video, image formats, and documents in addition to providing two-dimensional (2D) and 3D drawings and audio and video support. Cocoa touch is a layer that provides some basic infrastructure used by applications. The iOS architecture is based on three layers incorporated with each other. Apple iOSĪpple iOS is a closed-source code mobile phone OS developed by Apple in 2007 it is used by Apple-only products (iPhone, iPod, and iPad). Android applications are usually written in Java programming language. It offers a wide range of libraries that enable the app developers to build different applications.
Android is a Linux-based OS that uses Linux 2.6 to provide core services such as security, memory management, process management, network stack, and a driver model. Android Operating SystemĪndroid is an open-source mobile OS developed by Google and launched in 2008. In the next section, we will briefly explain each of these OSs. There are some other mobile OSs that are less used (BlackBerry, Samsung, etc.). The market share ratios of those OSs are Android 47.51%, iOS 41.97%, Symbian 3.31%, and Windows phone OS 2.57%. The most well-known mobile OSs are Android, iOS, Windows phone OS, and Symbian. For mobile phones, OSs have been developed to enable users to use phones in much the same way as personal computers were used 1 or 2 decades ago.
