You could have different options if you delete by mistake,
-an undo button like i seen when removing widgets and apps from home screen on this phone
-you could have an history/bin of the last 10 deleted recordings.
-or even just move the delete button higher up so you can’t press by mistake.
i would prefer that,
I was just making some noise and trying to record over because i was either messing the tempo or the notes, and that extra pop up was kinda annoying, it breaks the flow.
It just sounds like deletion with extra steps.

PS
I actually sent a feedback where i suggested to change the delete option by making a swipe action to avoid extra screens and accidental deletion , what do you think of that
