1. Introduction

   Dual-Boot Operating System for smartphone is designed to make the phone content easier to access the UI interface and device applications more immersive. Every Smartphone OS has a specific purpose to making all applications, content apps and to get access to the controls instantly without navigating back to the smartphone home screen every time we boot. The Dual-boot OS phone fits perfectly to any user such as beginner user or advanced phone user. The welcome screen on the Dual-Boot Operating System is designed to evolve over time to time to reflect the smartphone users' user activities on the device. The device Operating System is establishing the bridge between mobile OS and device. In the Dual-boot operating system the smartphone functions as a PC with one of the installed Operating System, Smartphone can also be connected to any monitor and display the Dual-OS on the monitor. When it is used as a dual-boot smartphone, it features a built-in dual boot drive in the Dual-boot Operating System, i.e., Master boot Operating System and Slave Operating System. Web applications can be installed as native applications on one of the dual-boot Operating System. With the help of Ubuntu OS for mobile customizing the own icons is very much possible on the smartphone and the same access to system notifications. Dual-boot OS for mobile enables dual-boot functionality during installation and it also enables to make

   your smartphone as like a personal desktop. Many applications can be installed such as Facebook, Twitter, Google Maps, Gmail etc. and it also helps in enabling and configuring the web app API's in operating system. The ability to dual-boot between the two different operating systems seems to be fairly reasonable one. OS uses the simple and the natural swiping gestures techniques from the edges of the screen to make it easier to access the smartphone content than ever and switch between various applications. Every edge of the smartphone is used to move it faster between the pre-installed applications, personal settings, Control panel settings and content settings.

   The Dual-OS also supports SDK tool kit for development process and API development. Remote boot-on feature is an add-on feature to improve its remote functionality to access the OS remotely over the internet.

   Run local applications and remote applications on a secure smartphone phone running with Dual Operating System. It acts as a new thin client of choice for the smartphones. Dual Operating System also enables the feature to handle the servers from smartphone, also can establish the connectivity with cloud infrastructure and desktops right away from the slave operating system. Basically, Dual-boot option is not set by default, it can be enabled by installing the slave operating system, which is based on Linux Kernel and Linux GUI. With the help of the Dual-OS slave Operating System, it acts as personal desktop running multi-Operating System. It is as smooth as personal desktop.

2. Dual-OS Design Strategy
