In this tutorial it is shown how to remove Phone permission on C-code games.
Step #1
Remove from all android manifests this line:
<uses-permission android:name=”android.permission.READ_PHONE_STATE” />
Step #2
All AndroidManifests should have minSdkversion like this:
<uses-sdk android:minSdkVersion=”16″ />
if it doesn’t have it, add it
NOTE: other permissions like Storage could be from third-party plugins like ad networks, and needs to be checked depending of the game
