But if you increase the shutter speed, there wouldn't be enough of an exposure unless they were able to increase shutter sensitivity and/or reduce noise, so that you'd be shooting at a higher ISO. But reducing noise is tough on such a small sensor. And the lens is so small, you're probably shooting at the equivalent of at least f11, so you're already stopped down quite a bit and without a larger lens, there's no way to open the lens more.
But you're right about resolution. Higher resolution will compound the problem because the photosites on the sensor will be closer together, generating heat, which causes noise in the image.
But that's the compromise when you shoot with a small lens/sensor. It's amazing it gets the quality that it does. While smartphone cameras are starting to kill off the low end of the point-and-shoot camera business, that's the difference between them. The larger the lens and sensor, the more quality you're usually going to get (and vice-versa). That's why pros shoot with "full frame" bodies - with sensors that are at lesat the same size as 35mm film was (36x24mm).
