5S Low light video
Even after the 7.1 update, the video camera on the iPhone 5S is still way too dark.
The photo camera is very good in low light, but video recording in low light is almost impossible it's so dark.
I also have a iPhone 5C for work, & although the camera is not as good as the 5S, for video recording in low light the 5C actually does a better job than the 5S.
So something is radically wrong with the 5S video recorder for capturing light. If you're not in a well lit room, it's almost impossible to record any video at all. (Ie, a night time or indoor concert is impossible.)
I have seen other people complaining about this online as well, so I don't think it's isolated to my device. I really hope it's not a hardware problem, but since Apple didn't fix it with the 7.1 update, I'm worried
