Hmmm that explains while the band is moving. Interference. If you tilt the phone in the z axis, banding is very minimal.

This would be a great improvement. I also notice this similar banding problem happening when I'm taking pictures under a bad flourescent light.

Try taking a picture of the TV or computer screen with a cam, you can see black bands move vertically across the screen, this is due to lower refresh rates but the black bands are not visible to the naked eye

100hz is the refresh rate of the tv screen, or scanning speed. It's supposed to give a sharper image. Many new uk tv are now 100hz.

My tv is only 50hz and banding can clearly be seen (like big black bars) my pc monitor is set at 80hz but also here banding is clear (smaller black bands) but my laptop screen (TFT) is set at 60hz and no banding visible.

I have sensitive eyes and I see clearly the blinking of tv screens set at 50hz or crt monitors set below 80hz. TFT screens that have no defect do not blink, so maybe the 60hz is a dummy setting or if it is really 60hz it works better than with CRT.

Yeah, like this one taken from a computer monitor.
or depending on the refresh rate of the monitor, the banding will appear differently.

As gov pointed out, the real reason for those bands to appear, would be interference fringes. As most of you know that light has dual nature (Einstiens theory of wave-particle dualism), so in the wave nature of the light, a certain amount of diffraction happens around the camera aperture. This diffraction sometimes causes opposite waves to cancel each other out, and make bands called diffraction fringes or interference fringes. Which is the dark band you see.
