I'm on my second oneplus phone and I am surprised with their update cycle, full OS updates and security patches coming well after other OEMs abandon their devices. Their android flavor doesn't deviate a lot from stock android of course which makes it easier and a lot of their features are done via stand alone apps rather than being baked into the OS.
