From version 2.3.5 onwards of the MMGuardian Parental Control app for Android phones, we’ve included additional anti-tamper protection measures. This extra level of protection can only be enabled from within the app on the phone. So, after upgrading the app to the latest version, please do open the app on your child’s phone and follow the on-screen instructions.
We’ll be upgrading the tablet app in the near future to also benefit from this extra level of protection.
