iPhone6 Since the update last week I am seeing graphics issues... The botton or top 1/8" of the background lock screen is distorted sometimes. 2 or 3 times it looks as if there are several app screens open at once and are mixed together. Also when I unlock the phone I'm seeing the search page upside down...once or twice. Once or twice, when I unlock the phone, the phone app is open and appears to have a call in progress but there is not one in progress. Yesterday 2 calls from the same number resulted in me hearing my voice with about a .5 second delay but nobody on the other end. The call was from a valid number & I was expecting the call. If I can't trust this phone...well you figure out what I will do.
