Use a Linux based phone operating system. Typically this will mean Android, but could also mean LineageOS or Replicant. LineageOS is the most preferable, because you can usually get an up to date image with a recent kernel which will give you better security against exploits. If you're buying a phone then look for a model which is supported by LineageOS. Replicant is the most free (as in freedom) but only runs on a small number of phone models. If you have a phone which runs a full GNU/Linux system then that's fantastic, and you can probably use it in much the same way as a desktop system and the rest of the advice on this page won't apply. If you don't have a phone capable of running a Linux based operating system then consider selling, giving away or bartering your existing one. Use a Linux based phone operating system.

So maybe you're running Android and the phone came with some apps already installed. Almost certainly they'll be proprietary. Go to Settings/Apps and then uninstall or deactivate any apps which you really don't need. Mostly preinstalled apps are intended to send your data to companies who will then sell it to advertisers or governments under the business model of <i>surveillance capital</i>. It's not a good idea to get caught up in that, and to avoid becoming addicted to apps which are surveilling you without consent or installing spyware in the background without your knowledge.

Encrypt your phone. This can usually be done via <b>Settings/Security</b> and you may need to fully charge the phone first. Encryption means that if you lose your phone or it gets stolen then there is less chance that anyone who picks it up will get access to your data, photos and so on. Encrypt your phone.
