I've been contemplating which device I will choose for my upgrade that's coming soon. I went into AT&T today to compare the two, and the biggest standout part of the phones were the displays. I've researched both extensively as well, and after looking at them in person, there's no comparison. The S3's brightness is ridiculously low, it makes everything appear dark, while the iPhone 5 is at least twice as bright in comparison. I can already tell the S3 would be nearly unusable outside. Also, taking battery life into account, full brightness would kill the S3's battery, which is the setting I'd need to really enjoy the viewing experience. I only need the iPhone brightness at about 60% to enjoy it, which wouldn't severely tax battery life. The positives are of course the large screen and pretty colors of the S3, but saturation on the iPhone seems up to par now as well. On the AT&T S3, I couldn't find any setting to change the color tone or the browser brightness like found on other S3 models. Maybe it's there somewhere, but I tried my best to find it. Just offering my perspective to those who may have the same concerns. Please no rude remarks or annoying sarcasm.
