At long last! And now I'll know why I pay more for an iPhone.
Although, for Android, there do exist apps that will do system-level ad/tracker blocking.
However, what you can do is utilize a VPN into your home network where you already have a pi-hole set up. Doing so will route all your phone's traffic through your home network (and pi-hole) first. You'll have the same "ad protection" on the go as you would at home. I recommend checking out WireGuard.
Please iPhone may be private but if you use Google search you lost already.
It is a double-whammy. You pay lot to apple and then lost privacy to google/netflix/cnn/<app> here or whomever.
