Actually would be interesting to see the content of the HTTP packets that are not encrypted!
I wonder what kind of information is shared by our smartphones without it being properly secured...
A lot. Running my phone traffic through mitmproxy was a rather sobering experience, especially what leaks on boot before firewall and ad blocker are ready.
On Android you can even inspect a lot of encrypted traffic using mitmproxy and the cert in generates, although some apps (like signal) use cert pinning in a way that i haven't managed to get around yet.
