Post Install

Things you should do soon after installing

Install some apps!

We created a list of recommended and tested apps here.
You can also get access to even more apps by enabling the included 'IzzyOnDroid' repo; be warned however that while all apps are largely open source, some may contain proprietary components/libraries/dependencies. Read more here at IzzySoft.

Settings to optionally change after install

  • Setting a lockscreen password of 12+ characters is extremely recommended, at the minimum please use a 8+ digit pin. Pattern locks are not recommended.

  • 18.1+: Change the connectivity check server via Settings > Network & internet > Internet connectivity check.

  • 16.0+: Enable USB restrictions via Settings > Privacy > Trust > Restrict USB > Allow USB connections when unlocked.

  • 14.1/15.1 only: Enable 'Privacy Guard' for extra control over application permissions.
  • Utilizing and configuring 'Profiles' for your uses/environment can increase battery life and potentially enhance security.
  • Disabling lockscreen shortcuts can potentially reduce potential lockscreen bypass vulnerabilities.
  • Enabling 'Increasing ring volume' is very nice if you don't use it already.
  • [DivestOS currently ships without VoWiFi support] You may consider disabling Wi-Fi calling to not let your carrier learn such information about IP addresses, access-points, and potentially more accurate location.

Physical Protections

Apply a privacy screen protector

Privacy screen protectors limit the viewing angles of the screen they are applied to, resulting in a dramatic reduction of what people and cameras around you can see. They can be purchased for around $8 on eBay and similar sites. The glass ones are the best as always, but some older phones seem to only have the plastic film ones available. Be warned, they noticeably reduce the brightness and add an ever so slight screen door effect. If your phone doesn't have the brightest of screens it will become near-impossible to see in sunlight and also impact camera/videos experience.

Keep a faraday bag handy

Faraday bags for phones can be purchased for around $10. They are absolutely essential if you have a phone without a removable battery and are in high-risk areas often. Putting your phone in their inner flap will prevent all relevant radio signals coming/going to your phone.

Wear a hat

Plain baseball hats can be purchased for around $6 and provide a decent reduction in visibility of your face to cameras.
