CPU-Z is a free application for Android devices that provides detailed information about your device's hardware. It reports on the SoC name, architecture, and clock speed for each core, as well as device brand and model, screen resolution, RAM, storage, battery level, status, temperature, and capacity. The app also includes information on sensors. It requires Android 2.2 and above (version 1.03 and +) and the INTERNET permission for online validation and ACCESS_NETWORK_STATE for statistics.

The online validation feature (version 1.04 and +) allows users to store the hardware specification of their Android device in a database. After validation, the program opens the validation URL in the user's current internet browser. Users can also enter their email address to receive a validation link as a reminder. The settings screen and debug feature (version 1.03 and +) allows users to remove the main detection features of the application and make it run if CPU-Z closes abnormally due to a bug.

In case of a bug, users can open the application menu and choose "Send Debug Infos" to send a report by email. Overall, CPU-Z is a useful tool for users who want to know more about their device's hardware and specifications.
