Best Android privacy settings

Android privacy settings that change something real: who can send you files, what the lock screen shows, a hidden space for sensitive apps, and the lock that fires if someone snatches the phone. Paths are for Pixel, with Samsung noted.

  1. How to turn on Theft Detection Lock on Android

    Go to Settings > Google > All services > Theft protection and turn on Theft Detection Lock. If the switch is greyed out, your phone doesn't support it.

    Use it when: A stolen phone that locks immediately is harder to rummage through than one that stays open.

  4. How to set Private DNS on Android

    Go to Settings > Network & internet > Private DNS, choose Private DNS provider hostname and enter dns.google. If pages stop loading, switch back to Automatic.

    Use it when: DNS queries leave the phone encrypted, which matters on a network you do not trust. A wrong hostname looks like the internet is down.

Questions people ask

How does Theft Detection Lock work?

It uses the phone's sensors to spot a grab-and-run, like a snatch followed by fast movement, and locks the screen.

Do apps in Private space send notifications?

Not while the space is locked. They're paused, so don't put apps there that you need to hear from.

Can I hide just the message text?

Yes. Pick the option that hides sensitive content. You still see which app notified you.

Does Private DNS block ads?

Not with dns.google. Some DNS providers filter ads, but this one only looks up addresses.
