Does anyone have problems occasionally with their slide to unlock on iphone 4s with the ios7 update? And do you think there will be a bug fix? Bit worried

Hi everyone,

I've recently updated my iphone 4s with the ios7 update and there was a bug fix I also downloaded recently but I hadn't noticed anything wrong at the time. I know it's not happened that often today but does anyone have any problems with their 'slide to unlock' button and have to reload their iphone again? Do you think there'll be a bug fix for it? Just worried as it's not old and I have a feeling I shouldn't have bothered with the update at all.
