I have no issues on Android 10. Very smooth, and gestures work quite well in my opinion.
As for the above post [which has since been deleted by a Mod, good riddance

], all I can say is that all devices have security flaws. I have a good friend who is a security expert, and he can break into pretty much any phone, and yes, that includes iPhones. You'll drive yourself crazy if you obsess about it. Be careful about apps you install (and stick with the Play Store, not 3rd party app sources), stay away from shady sites (like porn, gambling, "free" movies/music downloads), and secure your accounts with good passwords and 2-factor authentication.
