Lock screen on iPhone 4 says on for a while?

So when i check the time on my phone, it stays there for 13 seconds. It used to be for 5 seconds. I dropped it twice today… But nothing happened. This used to be with my iPod but now its back to 5 seconds. I've dropped my iPod way more times but haven't lately. My phone is 2 years old. My iPod is a 4th generation like my iPhone with iOS 6 and can't update it for several reasons. Will it go back like my iPod did? And yes I've tried turning it on and off!

Restore the phone

Never mind guys! It's because of the Assitive touch… I used to have it on my iPod and took it off… Then I put it on my iPhone and took off and back to normal!
