Unity builds a blank app

EDIT: This was a problem with the HTC One, not Unity. If I find a fix I’ll post it here.

Original post:
So I set about to create a game and had a map and some sounds implemented, but I can’t seem to get the build working on my phone at all.

Whenever I hit build and run, I get a black screen that does nothing. I don’t even see Unity’s splash screen.

I even tried creating a blank project and only loading the FirstPersonSetup.unity scene, and even that resulted in a black screen without any splah screen. Is there any fix for this? Where am I going wrong?

The phone I’m using has a Qualcomm Snapdragon which is an ARM v7 processor so I don’t think that’s the issue. I don’t see any warnings in the console either.

Any help would be very appreciated!

EDIT: Persistent googling in the past few days hasn’t led me anywhere yet.

Alright, this was a problem with the device, not with unity itself, so I guess this problem is resolved.

I am having this exact same issue. What was the problem with the device?

Thanks
