Iphone 4: Reacts slowly to screen touches; all actions slow to activate.
Any action attempted on the phone is delayed and slow to respond or activate. It mimics a computer that has insufficient ram, only worse.
Touch the screen to type....and it takes several seconds before the letters appear in response to screen touch.
Activating all apps or functions, whether internal to phone or involve a web response takes 3-4 attempts...as if the activation has "timed out".
Includes simple acts like opening camera or accessing settings. All take several attempts and long time to respond.
I also suspect carrier is slowing me down, but that would not explain the slow "phone only" functions.
iPhone 4, iOS 7.1.2
