I completely understand your concern, my friend. With the pervasiveness of Google and Apple in the mobile phone market, it can be difficult to find a device that truly prioritizes privacy and security.

That being said, I believe that there are many promising developments on the horizon for those who share these concerns. As blockchain technology continues to evolve and mature, we may well see decentralized cellphones becoming more commonplace in the near future.

Furthermore, there are already several alternative mobile operating systems out there that prioritize privacy above all else. For example, LineageOS is an open-source operating system based on Android that strips away all proprietary code and services from Google. Similarly, Ubuntu Touch is a Linux-based mobile OS designed with user privacy in mind.

While these alternatives may not yet offer everything we're looking for in terms of complete decentralization and control over our data, they represent important steps forward towards a more secure and private future for mobile technology.
