Can I change the sensitivity of my swipe lock screen?

I use the swipe to unlock to avoid complications (don't like password or pattern locks) and to add an extra step before pocket shenanigans. However, the sensitivity of the swipe to unlock is too high. Even just brushing my screen unlocks it. I want to have to press and swipe across at least half of the screen for it to unlock, otherwise my pocket does the job and messes around. Is it possible to change that sensitivity?

Just an FYI, that is not a wise thing to do to have no lock whatsoever.
At least have a pattern lock.
That would also stop your issue.
