This is ridiculous. Makes one wonder about the state of OEM development. It's not hard to build a CI pipeline for android. There is no good reason OEMs can't be running test builds of ROMs with security patches within hours, and have QA done in a day or two, or a week max.

Why wonder at all, it sucks and it's security is generally in shambles. Security is rarely very high on their priorities as features/prettiness is what sells their phones.
