One of the biggest advantages Android has over Apple devices is the ability to run customized and modified versions of the operating system, allowing for both cosmetic changes and access to features and lower-end features on your device. Custom ROMs give you more choice and control over your device, plus they can give you access to the latest Android releases on phones that are no longer supported.
Why I Don't Use Custom Android ROMs Anymore
Have you ever noticed how Android on a Samsung phone is different than on an LG or Motorola phone? That’s because anyone can take the base Android system, modify it, personalize it, and make it their own. Phone manufacturers do that all the time, but so do third-party developers. Android ROMs are simply modified versions of Android that are created by third-party developers.
Sometimes these indie developers are just one person repackaging Google’s Android code. But more often, they are entire development projects or even non-profit organizations. They create ROMs to add features and customization options to Android. Custom ROMs also support devices that may no longer be supported by their manufacturers. Typically, ROMs give you more control over your phone.
These ROMs are the best you can find to increase the functionality of your Android device.
