Google Android is the best Mobile working OS on the off chance that we take a look at its popularity and similarity, followed by Microsoft Windows OS and Apple iOS, alongside all that it is an open source platform, offering users to do a tons of customization without much issue, regardless I recall, attempting Android on an iPhone 3Gs, the result was poor, just 3-hours of battery existence with a great deal of Compatibility bugs and slack was the main thing we encountered much in it, nonetheless, Dual booting an Android smart phone is not a difficult job and even can you change the Primary OS to any else, instead of Android as long as it is developed on Linux.


Soon after the launch of Ubuntu OS for mobile, they were allowing users to make this OS as a secondary operating system on their smartphones for better hardware usability, but it failed in lesser times, then Mozilla OS came to the role although the OS is highly functional and robust along with a decent and clean interface. ZTE is the first brand to come with this OS. But developers have modded this software and made this usable on Android smartphone. I am not sure how many Android devices are running Firefox OS, but yes, if you have LG Nexus 5 then easily you can experience the all new mobile operating system with Firefox. Earlier also the developers have tried this on several devices, but there was some bugs and issues that are absent in this guide, I hope this is a great thing to know before going into it.
