It’s not a matter of wording, it’s a matter of function. See this screen? App locking IS already on. This is my nexus 7… I think I’m ok with blocking calls as this is a wifi only device. That first menu option about not having run a scan of the internal file system? I click ‘start file scan’ and it checks my wifi security. Check wifi speed? Also starts wifi security scan.
Everything seems to work normally on my galaxy s5 which has samsungs bastardized android 6.0.1 yet on a plain vanilla 6.0.1 on a nexus device it has issues? How does that make sense? Lol

Sorry if the image might not display but apparently the preview button is also broken on chrome for android for some reason. (Previews maybe once but won’t after that) Edited just to attach file instead
