Why does the light off an iPhone not show on a camera?

Yesterday it was nighttime and I needed to fix my hair so I pulled my iPhone out of my pocket to use the camera. I then realized the light off the screen was reflecting on my face but the camera just showed pitch black. Why was it dark when the screen was shining in my face?

Is your computer on? If so, try turning it off, and then on

Video cameras on phones are not as sensitive as human eyes.

Was it that hard to find a proper restroom?

  • Why is there a glowing red light in my iPhone 5's front camera? I never noticed it before but last night I was texting and I saw my front camera glowing red and its freaking me out! My boyfriend has the iPhone 5 too and his doesn't have that and I tried to look it up but there's nothing what do you guys think it could be? It glows pretty bright and blinks sometimes.
  • Why is the flash light on my iPhone not turning off? So my iphone drop in water a little bit thn I took it out and dry it off everything was good until the flash light start acting up and i don't know how to make it come off its like a little light there
  • Why does my iphone screen not light up or make any sound when i get a text? So my iPhone 5 will ring when someone is calling me and when I put an alarm on. But whenever I have a text come in the screen does not light up and it does not make its usual sound either. I don't know why its doing it! It started a couple of days ago. I've made sure the ringer is on every time and its turned up on full! If anyone has a clue that'd be great!
  • Why do I look gross on my iPhone camera, but not on an actual camera? I took two videos: one on my iPhone and one on my sister's new camera to test it out. On my phone, I look gross, blotchily red- and white-faced, every blemish is exaggerated, and my skin looks oily. On my sister's camera, I looked exactly the way I do in a mirror (well/evenly tanned, no extremely noticeable blemishes, not too oily). They're both 1080p, but my phone makes me look a lot worse. Even my really old 480p camera makes me look better than on my iPhone.
