Backlight of iPhone stopped working on deployment

I was test deploying a unity app in Xcode and the target device (iPhone5) had its screen go black either during deployment or shortly after when the app first started. After some trouble shooting I found the hardware issue was the backlighting on the screen had stopped working.

My question is could my app have caused it or is it fluke timing? Is it possible for a Unity App to cause this kind of hardware failiar?

Might want to ask about unity over on the unity forums. Good luck.
