To play Clash of Clans on Android, you need a device that meets at least the following specifications:
0.5 GB of RAM (1GB or more recommended)
Android OS 4.1 or better
A screen resolution of 800x480
We cannot guarantee these specifications alone will be enough to run the game. Devices are made for different purposes, and not all lend themselves well for gaming. Also, the game may be unstable if your phone has a modified OS or a custom ROM.
