Recently i bough a new phone and one of the reasons was because of this issue.
Let's say i'm listening to a song i like. I love repeating songs i like to learn them and possibly be able to play them, so i want to replay that same song. It's the first one i put on, and for some reason i can't repeat it when i'm in the lock screen. The "rewind" button doesn't work, all i can do is click the other one to switch songs, and only then can i switch back.
It may sound like a minor issue but it's getting on my nerves since i listen to music at least 2 hours a day and it doesn't work, i've tried everything i can think of.
Would be great if someone found a solution, thanks in advance!
