Hopefully, this will result in a culling of some of the ‘zombie’ apps from the Play Store. Zombie apps are the apps that turn up when searching for a specific app, that have similar names to the one you are looking for with none of the functionality. They often ask for access to sensitive data such as your contacts without good reason. Google’s action should hopefully result in less hubris to navigate through on the Play Store and that the consumer’s data is better protected.
If you are a developer, has Google been in touch with you, and will it affect your app?
