For App developers a problem is ensuring their apps continue to work through updates on operating systems as a lot of the time no matter how well the app is created, OS updates can be a severe problem. As you could probably already tell, App Developers have nothing to do with OS updates as that is the manufacturer's responsibility so they can’t just say to change a feature of the system because the developer's app no longer works.
