LED vs. Xenon flash
I have an iPhone 5 and a Nokia 808 as my personal phones. I use my 808 as my main smartphone/camera, and the iPhone 5 as a gaming/weekend.. entertainment device.
I've tried using the iphone 5's flash while going out at night with friends, and I must say its pretty much useless compared to the 808.
here is one example
Notice how much larger the iphone 5's jpeg file is compared to the 808's.. the 808 oversampling algorithm cleans up all the junk Combined with a xenon flash.. it works very well.
