Paranoid Android is one of the most popular and widely used ROMs in the Android community. Its most attractive feature is its highly efficient multitasking capabilities. This is possible because of two main features of the ROM – Pie and Halo. The Pie is a customizable replacement for the on-screen navigation buttons that are found in some devices whereas the Halo is a floating button that displays notifications from various apps on your phone without having to launch the app separately.
Now however, this Pie like feature can be installed on any Android device with an app called Pie Control. This has been made possible by XDA member EatHeat. The app acts similarly to the Paranoid Android’s Pie and offers almost all the functions that it provides. And the biggest plus point is that it works on all ROMs and devices running Android 2.2 and above. However, please note that the app requires that your device be rooted as some of its features need root access.
