Thanks for sharing. Htc one wins hands down....to no surprise really. Im not sure if youre privy to this, but the S4 only reaches its max brightness on Auto setting. I couldnt tell from the video if auto was selected or not. Its a close call between the OGP and the S4. I must say though, LGs screen coating is very reflective. I wish they would have used a less mirror like coating on the OGP. Also, like almost any phone on the market, there are screen variations for each phone. Between what ive seen between my own OGP, demo units, and a couple that i exchanged, some screen are "cooler" but less bright, and some are "warmer" and slightly brighter. Both screen types looked good to my eyes, and i wouldnt pick one over the other, but for outdoors visibilty tests, i think it would make an appreciable difference.
