If you are using `AsyncStorage React Native API, you need these 2 permissions (WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE).

For example, I use AsyncStorage to save user’s session id, in order to know if the user was previously logged when he closes and reopens the app. If I removed these permissions, I wouldn’t be able to invoke methods AsyncStorage.setItem (WRITE_EXTERNAL_STORAGE) and AsyncStorage.getItem (READ_EXTERNAL_STORAGE)
