Dome U camera pro won't connect

I just got my U camera pro and it just won’t connect!

It keep saying waiting to connect, but no matter where and how I present the QR code, it will just keep saying waiting to connect…

Any help please?

Oh no! That’s really frustrating. I am sorry to hear your having pairing issues.

Are there any cracks in your screen?
Start close, and gradually move away from the camera
Is the brightness on your phone all the way up?
