Just installed iOS 7 for my brother-in-law on his 16GB iPhone 5. He is experiencing significant keyboard lag. This is not just while he is in messages. The keyboard lags on any app that the keyboard is up (safari, mail, spotlight, messages). He presses on the keys and and it is delayed by about 5 seconds. When the keyboard is up, it also seems to lag other pressable buttons on that screen. Other than this keyboard lag, the rest of the software operates smoothy without lag. I've been running iOS 7 on my iPhone 5 since beta 1 and have not experienced any lag on my phone. Has anyone experienced this issue and have any tips on how to fix it? I noticed he had about 1GB left on his phone when I installed it. About 200 apps and 1000 photos were taking up that space, so I think all of this may be causing a slowdown but I am not sure. He deleted some apps but issue is still there. I told him to remove all his photos and import them to his computer, but I wanted to check here and see if something else was causing the keyboard lag. Any help would be great!!!
