I'm looking for a way to install Linux on my Android device without the risk of losing any of my data. Ideally, I'd like to set it up so that Linux becomes the main operating system, kind of like a launcher app. Additionally, I want to customize my home screen to fit my preferences, and I'm curious if I can achieve a rooted phone setup in the process. Any advice on how to do this safely?

Definitely do some more research! Check out specific Linux builds for your phone model. Remember, switching to Linux will require you to make significant changes to your system, so be prepared for that. It's not as simple as just installing an app.
It sounds like you might be a bit confused about what you're trying to do. Linux is a separate operating system, not just a launcher for Android. You can't simply install it on top of Android. There are some Linux distributions specifically made for certain phone models, but you need to do some thorough research on what's available for your device first.
