More than a few people around me are waking up and realizing that the simple cellphone is the weakest link when it comes to privacy.

Two of the best known privacy respecting alternative operating systems on Pixel phones are CalyxOS and GrapheneOS. I have tested both and made GrapheneOS my daily drive. But it is a matter of taste and threat level. Yes, threat level, as not everyone needs the same protection, or privacy. Some chose convenience or a camera as their buying point when choosing a phone. The mighty pen on a Samsung S22 Ultra, perhaps. Yet, when it comes to deGoogle a phone, you have Lineage, GrapheneOS and CalyxOS as the ultimate options.
