Usually any exchange of money in apps is going from you to the developers, but Google Opinion Rewards is different. It asks you questions, you provide them, and you get a few cents in your Google Play balance. It's a sweet deal, and the app just got updated with a few minor changes. Might as well have your survey answering experience be all it can be.

Here's the changelog posted by Google.

  • Support for landscape orientation on tablets.
  • Improved reliability in submitting answers.
  • Visual refresh of setup

So there you have it. Pretty subtle, but more descriptive than some of Google's changelogs. You can grab the update from APK Mirror linked below.
