Build Type: Binary Version: Version: 4.12.5-3039270+++UE4+Release-4.12 Description: RadialExponentGradial not displaying correctly on mobile (VR). Instead of being a nice radial gradient it has a hard cutoff between two colors. Hardware: Galaxy S7 + Gear VR consumer Attached files: A picture of what it looks like in the editor, oculus rift and previews and a txt containing the material. I am unable to provide a screenshot of what it looks like in VR/mobile, but imagine the black and the red with no gradient what so ever. Black canvas with red circle. Material ---

Hi Eirinn, Can you post the full specs for the Galaxy S7 that you have. Specifically needing to know what chipset is being used by the device. From what I understand there have been some issues related to the firmware/drivers related to the Mali and Snapdragon’s that is waiting on Samsung to resolve. Also, does this only happen in the GearVR or happen in a normal Android project as well? Thank you! Tim ---

It’s a European (Danish) S7. Unsure how to check the chipset fully updated Oculus/GearVR and OS. I haven’t checked a normal android project since it’s a VR only project we’re making. ---

Can you post the model number of the phone? With this I can see the specs for the phone. ---

This appears to be an issue only on the S7 Mali devices that we tested. I’ve entered [UE-34156](https://issues.unrealengine.com/issue/UE-34156) for this to be tracked. Thank you! Tim
