Question on Galaxy s3 / s4 and iphone cell video cameras resolution?

[Deer Film]

The iphone 5 and Samsung S3 has a 8meg camera, and both have 1080 video.

The new Samsung S4 is coming out, and maybe the new iphone, it will have 13 meg camera,(does not matter if the rumors of the phone are true or not) - my question, is there an increase in the camera video resolution with the increase of megapixels in the photo camera, does that make the 1080 video any better in resolution?
A man at the store said yes that the increase in the camera would give it better video. But thinking about this, the video size is not increasing, so how could it be better?

The reason I ask, is I use the video camera on a cell phone more than the photo camera.
And even though I own 3 Pro video cameras, my phone is always with me.
Thank you for any help on this.
If you have to choose a cell phone for only video camera options and quality and nothing else, what would you choose? It seems iphone has a great support group and video community and hardware options.

I'd choose not to own a cell phone.

In theory, it could be better because a higher-resolution base image is being used to make the 1080 image. Whether or not that holds in practice is a different question.

You need to take some video with both (enough people have both that you surely could find people you know who have them) and decide which you like better.

thank you, and my work pays for my cell phone bill, I just pick the phone. Otherwise I could not afford a cell phone bill.

There is no 'making better in resolution', if one is talking about 1960x1080 images... What down-sampling a larger image to the 1960x1080 may include is some antialiasing processing, and perhaps better averaging on intensity resolution, each improved by some 'small amount'... but I'm sure there is little processing of that sort in the hand held devices.

Since I have iPhones from the first onward, as well as iPads, 1, 3, and mini... I'd go with an iPhone just for consistency and not having to learn yet-another-sync tool...
