Version: 1.1 I apologize for the app not measuring accurately before; I created it just for entertainment and didn't focus on it. => Now it measures much more accurately with Shizuku/Adb/Root permissions. I tested it with two devices: a Samsung A9 2018 (60hz) and a Nubia Neo 5G (120hz).The results I think are correct or incorrect. Please use them and let me know the results. Thank very much..!
