Is there any way to dual-boot an android? I want to know if there's a way to switch from Android A to Android B, or even other OS if that's possible. I'm not a big tech person when it comes down to software, but the furthest I got in my research is downloading TWRP, Parted, and some booting manager.
Just know that I probably won't actually partake in this. I'm aware that I have no idea what I'm saying and that this is wayyyy out of my league, and that doing this will void warranty in most scenarios, trip some google services, and brick phones. But I just wanna know out of curiosity because there's not much information out there based off my 10 min googling and something like this really piqued my interest. I think it's weird that dual-booting is so common and accessible on PC, but hardly even considered on phones. It's a little sad how restrictive phones are especially with Apple (but yay sideloading!).

My closest lead I got to dual booting (I'm not even sure if this was relevant to what I want).
