mine is very dark indoor, almost black image using mirror app.i have not seen my front cam quality like youtube vidieo.but in sunlight it looks better.

i used smscon(it uses front cam to snap photo) and many people including me gets a BLACK image taken from the front cam.(search smscon thread for proof)

so how could that video gets so much better quality?(and this is blowing your mind ok)

this what i think.....

the video was perform in very much light,that is why quality is much better.you can his hands shining in the light.(that is what i think)
