Android Central Question

Hi all,

A couple of updates ago, my s9 was taking crystal clear images from a tv screen. Then suddenly, I suspect after an update, I'm getting moiré patterns (squiggly lines) in all of the images? Does anyone know what settings I can use to avoid these?

Televisions refresh their image line by line, a high shutter speed can capture this, a slow shutter speed hides it.

If you open your camera app and switch to the pro mode you can easily see what I'm talking about when adjusting the shutter speed.

As to why it took a good image if the TV before on auto but won't now I'm not entirely sure. Has anything changed with the room or general brightness in the area of your TV? That could effect shutter speed.
