Some tips for internet security.
I recommend using the Brave Browser since it automatically blocks trackers and ads. Plus it upgrades you to secure HTTPS connections. Otherwise I recommend Firefox with a few browser extentions to block trackers, ads, and enforce HTTPS. All of the recommended extentions are available on Chrome as well.
Download the Brave Browser for your phone.
Google records everything you search. Use DuckDuckGo search instead (you can set it as your browser's default search). You can also install their browser extension. If you ever want to run a Google search just add "g!" before or after your DuckDuckGo search. There are plenty of other "bangs" that make DuckDuckGo searches better than Google!
