The 1.FFPS meter is a very useful small software that can display the Android interface in real-time with a number of frames per second, very intuitive. In addition, the FPS meter can display maximum frames, minimum frames, and average frames, to evaluate the value of Android fluency. Because of the system functionality involved, FPS meter requires root. If you intend to try it, please use it before the root machine.
2.FPS Meter is very simple to use, start the app after opening the service. Within the app, you can choose where the number of frames is displayed, and whether to turn on average frames, minimum/maximum frame count display. When the service is turned on, you can see that there are frames displayed on the interface.
Note: The use of FPS meter to measure frames requires "Disable HW overlay" in developer options to be more accurate
