About 7/16 of an inch of my screen for my Iphone 4 no longer responds ever since the new update

Question

Ever since the iOS 7 update about 7/16 of an inch on my screen no longer works meaning if i where typing in safari an hit the globe button that changes the keyboard to what ever you have on your list (for example Emoji) i would end up having to back out of certain apps or have to turn my phone sideways to type key board style in order to even change the keyboard back to english that as well as all my buttons with in the 7/16 range no longer respond so if i wanted to delete an app i would need to drag it into an app folder and then move away from the 7/16 zone in order to delete it i have never had this problem until the update and although minor it is annoying. If anyone has any ideas on what is causing this to happen or a solution other then upgrading due my 2yr contract with At&t is still on going until next year.

I think the problem is that the iPod got set to Manually manage music and videos.  It needs to be set up for automatic syncing again.  Just unchecking that Manually manage music and videos setting does not do it.
In iTunes 12, select the iPod in iTunes (using the device button), so that you see the iPod's "management" screen.  In the sidebar (along left side of screen), there are two headings (Settings and On My Device).  Under Settings, click on Music.  To the right, you see the iPod's Music screen, where you tell iTunes how to sync songs to the iPod.
Check the box at the top for Sync Music.  That turns ON automatic syncing for music.  Below that, choose the option to sync Entire music library (assuming your music library fits completely on your iPod).  Otherwise, you can choose the option to sync Selected playlists, artists, albums, and genres and make your selections below.  Then click Apply.
