General why is FOV so narrow?

http://androidforums.com – I think the S4 is the best android phone but i dont like that much the camera. Still pictures in daylight are very good but video is not that good. It has a 13mpx camera so why is the FOV so narrow? if you activate video stabilisation it gets even smaller! The video quality is not bad but FOV is smalled than the S3 and much smalled than HTC ONE, why did samsung do this? I understand that you get more detail in a smaller FOV but you have a 13mpx camera and a fast cpu so why not make the FOV "normal" and get bitrate much higer like 22, 23mbs?! SAMSUNG are you reading this? ;) a (General)
