title: changing app from free to paid in android, how does this affect previous downloaders?
body: <p>So Ive decided to turn my free app into a paid app, the question I have is how does this affect people who previously downloaded my app, for example If I release an update in the future will the people who already dowloaded the app when it was free have to pay to download the update? this I would like to avoid as I dont want bad ratings in android market, thanks in advance! </p>
