Android Project introduced Project Treble to speed up the distribution of new releases. Android Project releases new versions, and the mobile phone vendors make changes to suitable for the hardware. This process requires too much workforce, and frequent updates from vendors are not possible. With the introduction of Project Treble, users can install Android latest version on their devices. Project Treble Android image can install on compatible mobile hardware same like installing an Ubuntu Linux on any computer. All mobile phones preloaded with Android Oreo (Android 8.0) at the time of purchasing is suitable for the Treble project. It means that the mobile user can download and install a Project Treble image of the Android operating system. The mobile users can check the Treble compatibility using the following app; they can be download from Google Play Store.
