2 Basic android securing

Which android phones do not leave gaping unpatched security holes?. *tl;dr — Google, LG, then everyone else.

3 Open-ish hardware: Librem

An alternative route is the Purism Librem 5. Their produc seems less to be a phone than a little linux laptop which happens to be a phone. It runs a hardened Debian variant PureOS which is a full desktop OS. Essentially this means you get all the resources and tools of the Open Source community’s auditing and development, and also all the horror of the Open Source community’s terrible UX track record, wrapped up in one device of unspecified battery life. It looks kind of fun, in a stubborn hobbyist kind of way. I wonder how secure this phone truly is on hostile networks. For sure its configuration is screamingly weird enough that generic attacks are unlikely to work.

2. track recipients subsequently on Tiktok and Toutiao even if cookies are deleted.
