Performance monitoring

Samsung is one of the biggest manufacturers of smartphones and tablets in the world today. Catering to different users, it offers multiple products of varying hardware specifications depending on their needs i.e. gaming, editing, and others. That said, it can be hard to tell whether that chip inside is being used to its full potential. A system performance monitoring tool like Perf Z can help.

This tool is made with simplicity and user-friendliness in mind with its clean and intuitive UI. Once enabled, it adds a home screen widget that displays four core system metrics, namely CPU and GPU usage, device temperature, and frames per second ticker. It will appear as a floating widget with a simple bar graph which you can tap on to expand and show more detailed information.

The app also has some customization options available to change the transparency level and enable auto-fold. Just note that you will need to have the Game Plugins installed for it to work properly. Also, just be aware that it will not update in real time and will have some delays depending on how demanding the app or game you're running at any given time.
