What is a Custom ROM?

# What is a Custom ROM? A "Custom ROM" is a replacement of the pre-installed version of Android that your device ships with ## Why would you want to install one? You might want to install one for more features, or faster and longer-lasting system updates, or possibly because the pre-installed firmware just sucks in your opinion for one reason or another ## Choice There are many to choose from, for instance [LineageOS](https://lineageos.org/), [ArrowOS](https://arrowos.net/) or [Potato Open Sauce Project](https://potatoproject.co/), just to name a few There are some ROMs which focus on Security, like GrapheneOS, and some which focus on customizability, like Resurrection Remix <span style="font-size: 10px;">(Resurrection Remix is dead tho)</span> as well as many others with different goals ## Other notes ROMs (usually) are device-specific meaning you cannot take a ROM made for a Galaxy S20 and install it into a Motorola, for example ### There are Official and Unofficial releases of Custom ROMs "Official" means that the ROM has been made in cooperation with the developers of the Operating system as a whole, like for example Official LineageOS is made between device-developers and LineageOS developers "Unofficial" means that the ROM has not been made in cooperation with the developers. Thus the device-developer has made it independently from for instance the LineageOS Team  *[ROMs]: Here: Modified Android Firmware based on the Android Open Source Project *[ROM]: Here: Modified Android Firmware based on the Android Open Source Project
