As far as I know, the is no approval process for the Google Play Store. Anyone can write and publish an app there without it being first reviewed by Google or anyone else for that matter. This being the case, as a future Android smartphone owner, I would like to hear from the Android users in this forum how they go about protecting their data and privacy within this environment. In my iPhone I download many apps that catch my interest just to test them and see if I like them, if not, I delete them. Due to the approval process of the App Store I feel safe in doing this since at least I know that the available apps are checked before they are made available. But without an approval process for apps to become available in the Google Play Store, isn't one very vulnerable to malicious apps that end up mining your data and uploading/publishing it elsewhere without your knowledge or consent?
