Horribly slow fps on galaxy s8

As stupid as it might sound, we are getting incrementally worse performance for our GearVR app on Samsung Galaxy devices. s6 performs the best at ~60fps, s7 at ~57-60 and s8 at ~25-30. We've tried unity versions 5.6.0f3 and 5.5.1f1 with similar results. We have also tried Oculus Utilities v1.13.0 and v1.14.0. Has anyone else faced similar issues?

The profiler shows substantially high amount of time for Camera.Render for s8(~12ms) than s7(~3-4fps).

Is this logged in Unity's issue tracker so we can get updates on its progress? I couldn't find it and I think it would be helpful.

No, there is no issue tracker,  we have directly contact with Unity dev team, it should be more efficient than external tracker.   we just get an update that they will start integrating the fix earlier next week.

I'm following Unity's website for patch releases - will update here if/when I see one.

[EDIT]: I've also raised a bug report with Unity but the team is in Europe and apparently the global S8 devices don't have this problem. I have followed up with them with no response yet. Will post any update here as well.

Right, S8 Europe is using samsung exynos processor, which doesn't trigger this bug.
A bit more updating from Unity:  a patched version 5.6.1p4 will be ship this Friday ( Jun 2 ) if QA testing was going well.
the fix will be also back-ported to 5.4 / 5.5, will update here when we got an ETA.

Didn't see anything in the 5.6.1p2 patch notes regarding this, did it make it in or is it slated for a future release still?

Eek, that's going to be a few weeks away for the 5.6 version fix...

We’re also experiencing very bad performance on the Snapdragon-based S8 devices.

So Unity 5.5.0b11 does not include that big.little change either, right? https://unity3d.com/unity/beta/unity5.5.0b11

Our project is using Unity 5.5.0p3, so a downgrade was relatively easy... However it did not fix the issue for us.
