We updated to UE4 4.13. Everything seems to work perfectly on the Galaxy S6 phones, but certain S7 phones are showing a black screen ( audio still plays ).
I created a simple project with a single map ( the standard default level with a plane and a starting point ) and have the same problem.
When comparing the hardware, the significant difference we found was that the black screen phones were using a Qualcomm Snapdragon 820 processor while the other phones used a Exynos 7 or 8 processor.
I tried turning on OpenGL 3.1 support but that didn’t seem to make a difference.
I also tried running an arm64 build (instead of the armv7). That displayed, but that didn’t run in VR mode; just a full screen monoscopic display.
The issue is fixed in the latest version of GearVR, which you’ll need to update, and you’ll need the code in 4.13.1 to go with it. That’s being released soon. The issue required a fix in the Oculus MobileOVR SDK to fix a race condition that was caused by the way UE4 initializes the renderer.
Same problem here~
It’s only happen on the S7 which with the certain CPU(Snapdragon 820)…Cause there are two different CPU on S7, so everything works on S7 which use Exynos…
And this issue still shows on UE4.14,please give an updata about this.
Thanks~
Is anyone here running into black screens with S7’s but not S6’s setting the screen percentage to something other than 100%? We’ve found a bug which would result in a black screen on Adreno S7’s when screen percentage is being changed. If so I can point you towards a possible fix.
