If you experience skipping when playing music on your iPhone, it may be a good idea to free up some memory.
Recently, when I was listening to music using the genuine music app, the sound started to skip.
It doesn't seem like the MP3 file is corrupted.
I thought it was a bit troublesome to restart and resynchronize apps/devices...
It seems that the skipping can be resolved by freeing up memory.
When I tried to free up memory using iMemoryGraph registered in the notification center...
The skipping sound has been resolved.
I don't really understand the cause of skipping, but
in any case, this method seems to be a good way to quickly fix it.
In my case, this resolved the issue for now, but if it does not resolve the issue, I think you may need to restart or re-synchronize the app/device.
After writing this far, I realized that perhaps sales of iMemoryGraph have been discontinued (as of the date and time this article was posted).
