I'm using an iPhone 4s 16gb and I've just updated to iOS 7. typing has become really difficult. The keyboard will lag for as much as 10 seconds after as few as 3 characters. Is there a quick fix for this?
My 4S was really bad right after I upgraded but when I woke up this morning, it was fine. I suspect a bunch of background processes were doing something and needed to finish. It's been speedy all day today. I didn't do a Reset.
