ROM stands for Read Only Memory and refers to your smartphones firmware that you are mostly looking at on the display. That firmware is based on open source software. The term open source means that anyone can download the software and edit the software to change features and move it in their direction. That is a lot harder than it sounds, but when we are talking about including some of the most passionate developers in the world, suddenly it’s easy to understand why so many people can develop the code.
There are many great Android developers out there, most of whom altar and edit the code to create new ROMs in their own spare time. They do it for free, and they do it for the love of Android and giving people like you something to try that’s new and unlike anything you’ve seen before. They get great enjoyment out of delivering something that the world loves to use and can rest easy in knowing that there are people out there, preferring to run their ROMs on an Android smartphone that the ROM the real Android developers had created.
AOSP stands for the Android Open Source Project, and it delivers an Android experience that is as close to stock Android as one could ask. AOSP ROMs are designed for the purists among you. Often these people can be the ones who prefer to experience Android the way the Android developers intended. Other times it’s people who are wanting to look after their device to the utmost maximum care. By running pure stock Android you are creating an easier life for your hardware and battery.
