Safeguarding your phone from network communication wouldn't be enough, as you would have to prevent audio communication as well - which kinda defeats the purpose of it being a phone.
I'd recommend to use LineageOS or Graphene on any Android smartphone. Use RethinkDNS [1] as firewall and AppWarden [2] to identify spyware.
You can also double check the reports page of the exodus prvcy project [3].
