Hello everyone, I'm pretty new when it comes to OnePlus 6T, I've been flashing different custom roms and I've noticed that when I try to install a rom sometimes it install it in either one of the slots, I don't change anything, like right now I'm booting of the Slot B, am I supposed to install the same rom in both slots or what's the purpose of having 2 slots, can somebody explain please? And please excuse my ignorance. Thanks in advance guys.
