I'm trying to use lineage at the minute, but xiaomi has made it next to impossible to even unlock the bootloader on my phone, and even then I'd likely need to move at least one of my banks as I seem to remember it not working on lineage, and I'm the target audience for a custom rom. For mass appeal it needs to be much easier, and without any compatibility issues with stock android. I cannot believe it's somehow standard to not allow bootloader unlocking on a device owned by the user, I am fully aware of the risks of it but phone companies insist on treating me like a complete idiot.
