I have three Android markets (Google Play, Amazon, and GetJar) on my Maxx. A chronic source of irritation is that those markets try to claim apps that have been downloaded from more than one source. For example, I downloaded and used the free version of QuickOffice from Google Play (i.e. it was the Android Market back then) for several months until the Amazon store offered the full version as its "free app of the day", so I grabbed it there instead. But...Google Play still claims the app and tries to update it (but it errors out due to not purchasing it through Google Play, of course). I have tried to limit the amount of overlap between markets as much as possible, but there are still a handful that are constantly erroring out, especially during mass updates. Is there a way to stop this? I'm open to settings changes, third party apps, or any other possible solution to this annoyance, so any guidance would be most welcome!
