Last but not least, you need to get yourself onto a different keyboard. OpenBoard or AnySoftKeyboard, perhaps FlorisBoard all come to mind. You can find all of them on F-Droid.

The Samsung keyboard will still appear after every boot if you chose a password option. If you do go with a PIN option (the more, the merrier) you can safely remove the keyboard from your phone. This can be with the delete, or uninstall option! However, make sure you do not use a password, but only a pin and do have another keyboard installed first.

Keyboard (be careful!)

pm disable-user --user 0

Remove Ads System-Wide​

Go to settings --> connections --> more connections settings --> Private DNS.

Set any of these:

In custom DNS
Close all apps, then reboot.

You can also have a look at controld, DeCloudUs or NextDNS, what gives you even more control over what you would like to block.

An even better solution is to get RethinkDNS or AdGuard as an app. This way you can set your DNS, but also block internet access for each app that should not have internet access ;)

You can combine RethinkDNS with any of the previously mentioned DNS providers or use the one RethinkDNS provides.

UnTrackMe from the f-droid store is a helpful app what redirects twitter, YouTube and co to privacy respected frontends.

This and last week's solutions should not just ensure a more privacy-friendly Samsung device, but will also gives you more battery life.

This Samsung Guide will not magically make your Galaxy into a GrapheneOS device, that is still the best operating system when it comes to mobile phones (IMHO) but it gets you closer.

Stay secure!
