It seems to me that now that I have ios 7 on my iPhone 5 that the sleep/wake button requires a more dedicated push to sleep the screen. Before, I could just press it quickly and the screen would shut off but now after numerous attempts, it seems as if I have to hold the button just an instant longer to shut the screen off. I tried different ways and any way that wasn't the long press would just blink the screen but the long press would complete the action. I thought it was a hardware problem until I repeated the action multiple times. Maybe it was done so there will be fewer screen shutdowns due to accidentally pressing the button. Am I the only one who has experienced this?
