I upgraded from 5s to 6s+. Phone is great but I'm having an issue that hopefully you folks can help with or offer advice. When using iMessage I can type all day in portrait. When I rotate the phone to landscape it seems that the keyboard does not function and actually nothing on the screen responds until I rotate back to portrait. This doesn't happen all the time but seems to happen frequently enough that it's getting aggravating. Has anyone else had this issue? If so any fixes? Is it iOS9 (Im using 9.02) or is it the phone itself? Many thanks in advance!
