Troubleshooting with iOS 7.1

Hello,

I just updated my iPhone 4S from iOS 7.0.6 to 7.1 and so did my mother with hers. The problem might seem minor but it keeps bugging me from the moment I realised it. The design differs from the two of them. The one works fine as it should but the other one seems to have lost everything that has to do with its transparency.

The first thing that made me see it was the Static Bar on the Home Menu. In previous versions of iOS 7 family, it was slightly transparent and you could see some colours from behind and the letters were white. Now, it's only Grey with Black letters.

Then, I saw my folders and the same thing occured. And I can't forget the "Mini Menu" (seems I can't remember the rightful name) that again lost its Transparency theme.
Lastly, I have a problem with getting a notification when a new mail arrives. Nowhere to be found even though on the menu its on to be seen on the Lock screen and the Notification Center and with an alert style on Banners. That has occured to me again with oldest versions of iOS and most of the time was fixed with a new update but now, the problem still stands.

On the left is a screenshot of my mother's iPhone 4S with iOS 7.1 and on the right is mine.

I hope that this will get fixed somehow. Even with some Update or someone's help that experiences the same problem(s).
I tried restarting it but nothing happened.
