Custom ROMs have been around since the early days of Android smartphones. They allow users to customize their phone's software to their liking, and many popular phones ship with a custom ROM preinstalled. However, with the increasing popularity of Google's Android version and the recent release of the Oneplus phone, it is unclear what the future of custom ROMs will be. Many users are now content with the stock Android experience and do not see the need to install a custom ROM. Additionally, bootloader unlocks policies on new devices are becoming more restrictive, making it harder for users to install custom ROMs. Custom ROMs may become less popular in the coming years as users move to newer, more polished versions of Android.
