The main function of DU Speed Booster is the ability to analyze your Android device and measure the processes that are consuming too much memory, trying to speed up the overall processing speed. That said, if all goes well, this tool should not find anything wrong on your end.
This tool can be especially useful on older devices that have a hard time running more modern video games.
Other interesting features of DU Speed Booster include the application manager, permissions manager, and call blocker. These are all accessible from one convenient and striking interface.
