iPhone 5 lagging in lock screen

Sometimes, very rarely the iPhone keeps me from sliding the bar for a brief 2 seconds.

Is this a software issue and has it ever happened to your iphone 5?

This sometimes happens on my iPhone 4 so i guess it's just a software issue.

Alright. I'm getting pretty scared because this shouldn't happen with a a6 processor.

Paranoid because I dropped it twice from 1 meter in a colcasack
