iPhone 6s Plus lag iOS 9.0.1
I'm using a 128GB iPhone 6s Plus (AT&T). Screen is unresponsive from waking the device after it's been locked for a considerable amount of time. It takes about 3-5 seconds before it finally starts to respond to touch. Can't go into any app or change home screens during this short period. After it starts launching and switching apps very quick and snappy but this happens a lot right out of the box. Another repeating issue is navigating the settings menu. The selection hangs for a bit before advancing to the next screen. Who else is experiencing this? Wasn't there a public beta? Come on Apple fix this.
