How can the my phone have an HD 1080p camera and still look like garbage?

I thought HD and 1080p were synonymous with good quality? Can someone explain the point of having a such a high resolution if the resulting image is still crap?

It's not synonymous with quality but a lot of people think it is. The reason they have such high resolutions cameras on cell phones is that people assume that because it has that spec that it must take good video when you've noticed that obviously isn't always the case.

The technical reason why it looks so bad is that the sensor on a cell phone camera is really small. When it's that small it doesn't have a lot of surface area to capture light and so it will perform poorly in all but the best lit scenarios.

Also, the glass of the lens won't be nearly as high quality as a dedicated camera.
