Having one page for each topic and providing a link to a relevant page when it's useful means that it's less likely that contradictory or outdated information will be provided. The link to the "android distributions" page is currently quite prominent: https://github.com/privacyguides/privacyguides.org/blame/78726b4c4af8bee974559398c1920ea0f65cd2dc/docs/mobile-phones.md#L37

The "mobile-phones" page is currently quite coupled to Google Pixel phones right now. I would prefer for there to be another type of phone that has been found to be suitable to use, but in the meantime while that is not the case it's probably better to have a page that explains Google Pixel phones in a great amount of detail and indicates that information about Recommended Android Distributions is important.
