I have been using an old samsung tablet with lineage os (android 12), but the last stock rom was android 6.

So yeah, for me the ability to unlock the boot loader is a must. And that’s not even mentioning getting away of spooky-ware I got as a gift a Huawei phone, really good phone but when I tried to search an app using the sistem laucher it fucking asked for a lot of data, fingerprints, etc. I was sorry to this person but I just sold it ASAP since I wasn’t able to install a Custom Rom to get away from all that crap.
