GVR Reticle not centered on android phone anymore.

Left a build I had on my phone for around a month and suddenly the reticles have moved to the corners of the screen like so:

Guessing this is an issue with an update by my phone but could be wrong?

When I play in unity (5.6.2f1) the reticle is still centered.

I am using the GvrReticlePointer attached as a child to the main camera.

Any ideas what could be wrong please.

Looks like it was a problem with an Android update changing the screen resolution of my S7, changing the resolution back to 2560X1440 sorted the problem. The vrservices app didn’t register the change but apparently they’re bringing out an update that will.
