I have a moto g 5g 2023 which is apparently different than the moto 5g, and an A9+ tablet. I found a thread talking about the difference and some regional reasons why my phone and others like it don’t always have support. It looks like versions of these OSes often just don’t exist for a lot of devices, because fewer people use them. The lineage website did have a lot of samsung devices listed though and might have yours, so there definitely are some options. But it’s not every phone, which sucks, but i think the warnings about bricking are real and not just discouragement.
Honestly opening up software on consumer devices should be the law and mayyybe one day it will be in the us (eu allowed some semblance of alternative app stores recently and that’s something? ) but I think those of us with the less common and budget mobile devices might just have to wait for now. Or continue living inside the matrix, as someone else here said.
