Currently, the Vodafone Smart Prime 6 is running the Android 5.0.2 OS. This version is incompatible with certain utility apps. Mainly app lockers will not work AT ALL with this version and the ability to monitor running processes on a phone, through certain apps, is unavailable.
This only started to occur after I updated from 5.0.1 to 5.0.2. It would be nice of this issue could be resolved.
