You Must know this about android Operating system
Google never buils à Mobile OS , they just acquired which means that Android has lot of things to improve .
It keeps bringing new versions and updates but still have to do more improvements mostly when it comes to Battery Life and security such as malware protections etc .
Google still allowing smartphone makers to use Android by respecting and following Google’s recommendations , that’s why we call android an open source Mobile OS that you can also use when you decide to launch your own Mobile Phone company .
Google Android would have been better if Google stop giving smartphone makers a license to use Android operating system and will allow the company focus more on security , enterprise mobility and other issues and challenges to make it a better Mobile OS .
It sounds a little bit funny but it would open the smartphone market and will also encourages smartphone Giants to focus on making their own mobile OS .
