as long as you’re not downloading sketchy stuff and have safe bank-keeping measures, keep using the rooted phone. As a matter of fact, I’m considering rooting my own galaxy s10e sometime soon and installing a quicker version of android. Mine runs on a Exynos chip and OneUI is starting to get slow. Really slow.
also muuuch better speakers, and the screen is a Mini-LED. Unless OP absolutely needs the portability of the air (which at 15" isn’t that much compared to the 14" pro), it would be absolutely insane to not go for the pro.
