Left eye rendering incorrectly - GoogleVR, Unity 5.4.1f1

I’ve been working on a cardboard VR app in Unity 5.4 for a while and have published a short demo of it on the play store some time ago. It plays fine on my ZTE Axon 7, but now I’ve started getting bug reports for different users using various other phones. The left eye is rendering incorrectly as you can se on the screenshot attached.

I’ve tried to find a solution on the internet for some time, but nothing has worked so now I don’t know what to do to fix this. Any ideas of what could be the problem and how to solve it?

Can you provide a list of what phones are reproducing this issue?

So far these two devices have been reported:

Samsung Galaxy S5 running 6.0.1
Weimei Wei

The users also reported that playing any other cardboard apps works fine on their phones.

Can you provide a link to your store application or an actual APK? There may be something that we can do systrace wise to see what is up.

Yes, here’s a link to the app on the play store: https://play.google.com/store/apps/details?id=com.RealXP.NeuroRealDEMO&hl=en
