CONCLUSION We have seen various mobile OS & their features &

comparison. For developers the OS is an ultimate platform to

develop apps innovatively & publish in market very easily. Not only in mobile phones, the OS is diverging in various fields like Tabs, Smart TVs and Cameras etc.

A mobile OS should be a result of factors like user experience, battery life, cloud readiness, security & openness. A successful mobile OS is a result of a design between software & hardware together.

Now-a-days, android is most popular used mobile OS.
