Sorry if this annoyed you, but just because there are some apps and workarounds doesn't let Apple off the hook for their interface being flawed.
I wasn't going to respond to the thread until I saw all the defensive posts basically dismissing the OP. The issue, albeit minor, is real. It was an issue in 2011, was an issue in Nov 2013, and is still an issue in April 2015.
I'm starting to have problems with this as well. Noticed it more now that I've moved to iOS7 and a iPhone 5s. Don't know if it's the sotware or the phone but it's common and annoying.
And, no, I'm not going to carry around a BT keyboard to go with my phone.
