Check this link. This will help you to install Goodlock.
For users of region where Goodlock is not officially available, I will explain how to install Goodlock.
Install Windscribe VPN. Set country to US. Clear data of galaxy apps. Remove your SIM with out switching off your phone. Now restart your phone after SIM card is removed. After restart check if VPN is on, if off manually turn it on and set location to US. Go to galaxy apps and search GoodLock and install it. Open goodlock and install all modules from goodlock. Now you can turn off VPN. Thats it. Enjoy goodlock.
For all those who are lazy, I have those apps uploaded into my Google drive for you to download. Use the link below, download all the apps, install all of them and enjoy goodlock...
Otherwise install all apps except goodlock and install an app called NICE LOCK from play store.
