I have a Samsung Galaxy On7 with Android 5.1.1. The phone has a bug that makes video apps like YouTube, NetFlix, Facebook (and others) lag in the videos. Almost every video opened lags in the first 7 seconds, the same happens when the video time is advanced or retracted. I've searched a lot but I didn't found any solution for this problem. I wonder if there is any way to fix this error (even with root).
