Samsung's Android 5.0 Lollipop update for the Galaxy Note 4 has been held up by Oculus, which is "busy tweaking the kernel for [Gear] VR," it is claimed. Samsung has already begun issuing Lollipop updates for the Galaxy S5 and even 2013's Galaxy S4, but those with the company's latest phablet will have to wait.

If you're a Galaxy Note 4 owner, you've probably been wondering where your Lollipop update has gotten to. Samsung traditionally makes its software updates available for its latest flagships first, and although it may have planned to upgrade the Note 4 earlier, one of its newest and most exciting smartphones available is still stuck with KitKat.

But the delay isn't strictly Samsung's fault. Thanks to its exclusive partnership with Gear VR, the Note 4's software is a little more complicated; it needs tweaking by the folks at Oculus — whose technology is used in Gear VR — to ensure complete compatibility.

According to Faryaab Sheikh, editor-in-chief of SamMobile, this is what's causing the delay — despite denial from Oculus VR CTO John Carmack.

It's unclear for now how long Note 4 owners will need to wait for their Lollipop upgrades, while older Samsung handsets get theirs. But we know the South Korean company is working on it, at least, so we could see an initial rollout any day now. We've reached out to Samsung for a timescale, and we'll update this post if we get anything.
