Mullvad, IVPN, and Proton are the top tier for privacy respecting VPNs.
Windscribe and AirVPN are also decent options but do not have the audit history to be in the same tier as the other 3.
Most other VPNs people mention either have a dubious history or no real proof of their claims to be privacy respecting.
Its a pretty low bar but Android is going to be more private then Windows. Google having privileged access to your phone is still terrible but Windows doesn’t really have any privacy protections by default. Android at least does things such as sandboxing its non privileged apps. It also provides a lot better hardware security for your data then most Windows devices would…outside of secure core pcs its pretty trash for hardware privacy in the Windows world.
