Even in the face of Apple’s rigid app approval process, some villainous developers still strive for ways to take advantage of unsuspecting users. In order to help combat one of these scams, Apple has started implementing new policies regarding developer control over App Store screenshots.
The problem occurs when a developer submits one app for approval – usually a very simple, or otherwise unattractive program – but then after that app gets Apple’s approval, switches the app’s App Store screenshots with some showing a much more interesting product, one far more likely to convince a user to make a purchase.
As of now, Apple is locking-down screenshots, and developers won’t be able to readily swap in new ones. Of course, apps do evolve over time, and you don’t want the App Store showing an out-of-date product, so developers will still be able to add new screenshots, but only when they also submit an app update itself.
