Samsung will no longer support paid applications on older versions of Android. In an email to its partners/developers, the company notes that older versions of Android starting with Ice Cream Sandwich going backwards (that includes Gingerbread, Honeycomb, Froyo and Eclair) will no longer be supported for paid apps.
This means that users with premium content from the Galaxy Apps store either through in-app purchases or outright app purchases will need to be using devices running on at least Android 4.1 (Jelly Bean).
The changes take effect on 28th April globally. In Iran, the changes take effect two weeks earlier, on 14th April.
According to the latest statistics from Google, those older versions of Android only account for just 5% of all the Android devices with Google Play services installed.
