When iPhone locks with code and app is playing, after waking it up, the app doesn’t show any graphics, only a blank (Black) screen. However, it keeps playing mixtapes if you’ve been playing them on opening the app. Please look into this.

Thanks for reporting this. We have a fix for this which we're hoping to release next week. Pacemaker 2.7.5 once avaliable will no longer cause this to happen. You can check your Pacemaker version by opening the iOS settings app and scrolling to find Pacemaker in the list of installed apps.
