Hello everyone! I recently purchased an unlocked iPhone 5S gold and noticed something that my 5 didn't use to do: when I turn on my phone, after it starts up and shows the white background with black apple logo, the screen immediately sleeps/turns off. I would have to press on the home button or sleep/wake button so I can swipe to unlock my phone. With my iPhone 5, it used to stay on for 2-3 seconds to give me a chance to swipe/unlock my phone before the screen sleeps. But now, my iPhone 5S' screen sleeps immediately that if I don't watch the phone while booting up, I wouldn't even know it's on because it happens just for a split second. Does anyone else have this issue -- or is it even an issue? My husband who has the same one but in silver remain, his screen stays on for 2-3 seconds before sleeping. I was wondering if there are others who's on the same boat as I am. And if so, does anyone know how to adjust that? Thanks in advance!
