This is a very comical bug because as a programmer, I haven't found a 100% reproducible step. I have this problem on both my phone and pad, where only the button for the previous video is always valid, and the button for the next video is likely to be gray or clicked without any response.
But what I know is that most of my video folders can use the button for the next video normally, and it always fails when I record and transfer new videos.
There is also an extension issue. When I was testing, I found that when I quickly and continuously clicked the up and down buttons, the sound played normally but the screen went black.
