Press the round button on the I phone on the bottom fast twice (the big one with a square in the middle). On the screen bottom you'll see apps pop up. Hold your finger on an app icon until a red - appears. Hit the red - to close out all the apps, these run in the background and slow the phone down. Turn off your phone and wait a few minutes, once on again it should run better.phone didnt post: thanks. was hoping it would give a clue why a new app is sooo slow, but nope.
