Note: 1. I did not optimize any settings except switching between normal and night mode. 2. I'm not good at taking pictures. 3. Do not use this to compare other pictures from other phones, it's only suppose to show you how effective night mode is on the Vibrant. Now, with all that out of the way. Here you go, judge for yourself. Here it is on default mode, normal mode, or whatever you want to call it. Here it is on night mode. The only light source is through a closed blinds window behind me. This is the best picture I can take to show you how effective night mode is. Hope it helps! Now, do you REALLY NEED that led flash? Really? P.S. No, this is not photoshopped. I'm not even sure I would do that in photoshop anyways.
