MrStreisand There really is no one "best" way to set up your phone with profiles. It's really up to you how you want to do it.
I personally wouldn't suggest having Sandboxed Google Play running in a profile you're not even using. To me that seems like a waste of battery for none of the benefits. Two profiles with Sandboxed Google Play will just suck up more battery faster.
If you want to use a primary profile with Sandboxed Google Play, then why not just use only the Owner profile, or keep the Owner profile completely empty and use a secondary profile for day to day use?
I personally do it the second way. I think it's a better setup for multiple reasons:
- If I want to save battery, I can always terminate my profile but I don't need to restart my phone.
- Personal data can be put to rest easily, no reset needed.
- If I want to be extra paranoid, I can use other profiles after ending the session of my regular use profile.
- Profiles can be set up to forbid running in the background if you want to use extra profiles for other purposes.
- After a reboot anyone with my phone would have to enter two different passwords to get to my personal data.
- Certain system settings are only accessible via the Owner profile, so a password is required to change certain settings (some might find this annoying, but I like it because it's more secure, but it's true it's annoying for some other settings).
