Here’s the thing with unofficial Android upgrades: they don’t have complete coverage in their security updates. LineageOS and Amazon can’t generally provide security updates for older chips. Only Qualcomm can compile new kernels for the Snapdragon 800, say. And Qualcomm stops giving you updates after four years (recent change: it used to be the three). The updates LineageOS and Amazon and anyone else provides are updates to Android’s open source components. That’s all great - but they’re not complete security updates, and driver issues are a big vector.
