Inspired by the popular Desktop application CPUID, XDA Developers found a way to identify the CPU inside devices based on the Processor Information it returns.

ARM CPUID is such a small and free application which needs no installation and that, upon launch, returns the Processor Information of your Device’s CPU. Unfortunately it only returns the code and it does not translate it to a model number but you can check the thread over at XDA Developers to see a list of translated returned cpuids. In the screenshot below, there’s our CPU: Qualcomm MSM7201A (Diamond, Raphael, Blackstone): 0x4117b362.
