Looking at other forums and websites, the instructions to download Good Lock tells you to search it in Galaxy Apps. However, there is no such item for me in Galaxy Apps. I then tried to install Good Lock using an apk file, which restarted my device after installation, but does not show up as an app anywhere, as if the installation did not happen. Any solutions to this? I would really like to use the Good Lock app but my Note 5 does not seem to be cooperating. Thank you.
