OK, let's be real – do Android updates matter that much to you?
But let's slow down and think about this for a second. Samsung and LG have long had their custom interfaces on top of Google's OS and they both look radically different to the vanilla Android. On top of that, features like multi-view (split screen), fingerprint scanner support, and battery-saving were present on many 3rd party skins before Google made them native to the OS.
So, if you are a Samsung user, for example, the only thing you gained, feature-wise, in the past 2 years were two facelifts of the operating system. Everything else is still there as it was before, simply because it was there before Google implemented it.
We thought we'd ask you — does it really matter if you are on the latest Android? Do keep in mind, that we are not talking about the security updates here. These should be regular, on time, and hit every contemporary device, there's no arguing that point.
