I saw someone post something about being able to transfer paid apps to another phone and i think mentioning something about having to keep the receipt/email along with the app in order to get it to work right on another phone. Is this true? I've been looking for the person who posted this in another thread and cannot seem to find it anywhere. Am I suppose to transfer the APK to another phone and then sign into my google account on the other phone and keep the email receipt on that phone? Kind of far-fetched work-around but just wondering.
