Android is not secure and I don't think you can save your phone from hackers so easily. I have seen many SPY apps like these https://bestforandroid.com/spy-apps-android/ which can work remotely and don't leave any sign in the phone which may cause detection.
If you want security then Go for iOS. iOS is much more safe and secure.

Here are some of my favorite apps for rooted phones.

SuperSU is one of the most important and essential apps that you should install right after rooting your Android device. It is designed to keep a log of all those apps asked for root permissions as well as the current permission status. It is created by the popular Android apps developer who goes by the name of Chainfire.

Greenify: Have you ever seen an app consuming your phone’s entire RAM, battery power, and making it slow? If yes, then you should try Greenify as it can hibernate those apps while you are not using them. The moment you exit the apps, Greenify will hibernate it to save battery while improving your device’s performance.

I have seen more amazing apps for rooted android phones here https://bestforandroid.com/root-apps/. Rooting is tough process these days by the way. I haven't rooted my Android phones currently. Otherwise, I would have more apps.
