Android是伟大的，但有时，版本你与你的手机得到

One of the best things about the openness of the Android platform is that if you’re unhappy with the stock OS, you can install one of many modified versions of Android (called ROMs) on your device. A new ROM can bring you the latest version of Android before your manufacturer does, or it can replace your manufacturer-modded version of Android with a clean, stock version. Or, it can take your existing version and just beef it up with awesome new features—it’s up to you.

If you’re familiar with Linux, it’s sort of similar to installing a different Linux distribution. Each version of the OS has a specific goal in mind, and as such differs quite a bit from the others. Which one you choose is dependent on your priorities and how you use the device. You’ll need to unlock your bootloader and flash a custom recovery (more info on that here), but once you get the hang of it, it’s not too difficult.
