I am using Marshmallow, and I use the built-in encryption mechanism. Typing my password every time the screen locks is a pain. I would like to leverage Smart Lock to have the following ideal situation:

  • If my phone is far away from me, I'd like the phone to immediately lock; thus requiring a password to decrypt. (This way, if my phone is lost, or even stolen, then my data will be safe.)
  • If my phone is nearby me, I'd like it to simply "soft lock" my screen; i.e., require either a PIN or facial recognition to unlock the screen, but not my full password. (This way, if I leave my my phone at my desk at work, for example, someone sneaky can't snatch it and snoop at my text messages or who knows what.)

Before I go on a wild goose chase, can someone please tell me if this setup is possible with Android?

  • As I feared, the answer is most likely that there's no such thing as a "hard lock screen" in Android. Unfortunately, the only one that exists is after rebooting the device. More information here: blog.cryptographyengineering.com/2016/11/24/… – Jay Sullivan Dec 21 '16 at 21:27
  • Worst-case, you could use tasker to reboot your phone whenever you leave it alone for too long. – Ajedi32 Jan 19 '17 at 14:57
  • @Ajedi32: If someone explained how to do this, I'd be up for trying it. – Jay Sullivan Jan 19 '17 at 15:22
  • @Ajedi32: Actually, I think that'd be drastic. What would be great is if it auto-rebooted once it's too far away from me. – Jay Sullivan Jan 20 '17 at 2:37
