I'm going to call it bs.
LG G2 is a good phone. No doubt (all the flagship phones are excellent). That's why after I compared the two phones at the local Verizon I decided my purchase of M8 as I couldn't tell the difference in the photos I took at the store in indoor normal lighting conditions. I trusted G2's cam. Both Verizon stores I went testing the phones have LG and M8 on the same stand. Very easy to compare them. Anyone can go and TEST THEM YOURSELF.
I have an important report due tomorrow and been very busy. But today I took a lunch break and went to 1 of the Verizon stores again to test the phone cameras. Last time I didn't test them in low light conditions. As the store was well lit but you couldn't move the phones much away from their stall as they're attached by a cord. To try indoor low(er) light conditions, I tried shooting (just seconds apart for the 2 phones) at the spot under the stall that both phones sat atop. The phones under test were held at the same height. Repeated several times to make sure it wasn't due to unsteady hands should some blur occur. Guess what? All M8 photos came out clear and you can even zoom in a bit. And the photos taken by G2 were not bad, for the standards for most phone cams under low light condition (the light wasn't very low compared to what I'd tried with M8 in some night shots). But it wasn't as sharp as those on M8. FURTHERMORE, when trying to zoom in, they got blurred. So much about 13MP.
And the color, G2 photos appeared to have a bit blue tint. Not bad. But it shouldn't be bluish.
I'm not saying G2 has a bad cam. You've got to understand all these cams have their strength and weakness. G2 has multiple focus points in a frame as compared to the single (centered) point focus on M8. But it takes considerably longer to get focused and snap a good shot. I tried G2 cam today to take several pictures of the people in the store moving a bit at few sec apart (~2sec). In that attempt, every movement was blurry on the photo because it couldn't get focused well (it'd be less an issue in brightly light outdoors for G2).
I'd like to post those G2 and M8 photos here and let the photos speak for themselves. If somebody has any ideas I can achieve that w/o having to buy the phone (G2) then return it, please let me know. I'll appreciate that.
Be honest, I still don't understand how you took those shots as the questions about the pixels I asked was not answered.
