PC users probably already know what CPU-Z is. It’s a free tool for detecting and showing system information. Many PC enthusiasts use it for overclocking, making sure their settings are sticking and that their hardware is working properly. It’s a simple but useful app.
But the best part about this app isn’t what it does, but how much it does for its size. The app takes up only 700kb of space on my Galaxy S 4. It’s tiny, lightweight, and very useful. You really have no reason not to install it, considering it’s free. So assuming you’re on Android 3.0 or above, hit the source link and start exploring what the app has to offer!
