Microsoft’s first purpose-built Windows 10 flagship devices are beginning to arrive in markets worldwide, and despite being the first high-end Windows Phones to come from the firm in recent years, they may not be the 'ultimate' devices we've been waiting for. While the Lumia 950 and Lumia 950 XL are remnants of its Nokia acquisition, Microsoft has supposedly been working on delivering its first mobile device to originate from Redmond.
Mozilla has released a Developer Preview of its Firefox OS which can be installed on Android devices as an app, with a slightly limited feature set compared to the full blown OS.
Firefox OS is a lightweight operating system which relies heavily on web technologies in its apps and overall user experience, and the Developer Preview brings the same experience to Android as an app. Just as other launcher apps on Android, the preview app will replace the standard launcher and drawer on the user's device with the Firefox OS one. It includes most apps from the full OS except for system apps such as the task manager, utility tray, navigation keys and settings.
