On my phone (Pixel 5) I don't need to unlock to take a picture (double click on power button) or switch to the next song (slide menu down, click Next).

Not sure if it helps. Have not tried the app yet.

Edit: sorry, didn't see the almost identical answer

As mentioned elsewhere, I have double-click on power button bound to toggle the flashlight, as I find it way more useful day to day, plus quick launch of camera becomes redundant after you launch the app.

As for songs, I specifically mentioned picking a next song. As in, picking from a list, possibly navigating or doing a search first. Next/prev is both trivial and something I rarely use anyway.
