If you want to make sure that the Android apps you have installed on your mobile phone are completely safe, you can try FSecure App Permissions, an application that allows users to identify programs that hide potential security risks.
The “dark” Android applications usually require many more permissions than needed under normal conditions. For example, a game does not need to have access to your contacts and a video player should not request permission to collect GPS data. The F-Secure app can help Android users precisely determine which programs they can trust.
The app is easy to install and use, and can inform you about which of the apps you have installed may incur charges or have access to confidential data.
Another useful feature is that users can filter applications based on specific criteria, e.g. based on the total number of permissions they require, based on battery power consumption, or based on the cost they incur.
You can download the application from here.
