If there is anyone who is going to find a leaked version of Android online, it’s going to be some of the best third-party developers out there for the Linux kernel that is in existence. That’s why it’s no surprise that we often see custom ROMs become available that are ahead of the official released we get from our smartphone and tablet manufacturers and phone carrier networks.

It’s no secret that one of the most popular reason why one would want to update to a custom ROM is to start using a later version of Android. Everyone owning the HTC One M7 as we head into the middle stages of 2016 will know what I mean. Our smartphones and not supported anywhere near as long as some other technology we have in our homes like a computer. Bill Gates and company can support our desktops for more than a decade. However, when it comes to our smartphone which cost around about the same money for the high-end select few, they only get supported for a few years at best. Anyone without enough money to upgrade will then need to look the way of a custom ROM for help.
