IPhone 4S calender in iOS7

Question

WIth iOS7 (as in previous versions) the calender entries may be seen in 2 views - a long list (Black and White) itemising each entry separately even if there are 3 entries for one time of the day, or as what I would call coloured entries (depending on the colour calender codes one sets up - work, pplay, school etc). The latter comes as a block of colours - a format that I don't find so easy to work with.
WIth iOS7 it would appear that you can only add things to your calender on the "coloured page" by tapping the + sign at the top right of the screen.
Previously (in earlier iOS versions) I could also add calender items on the "Black and White" as well by tapping the + sign at the top right of the page.
This + sign does not seem to be present with iOS7 on the black and white page layout.
Comments welcome as to how and if I can add the + sign to the black and white page (?? via preferences) so I can add things to this more simple calender layout  Thank you.

You're welcome. When you state you have tried all of the suggested fixes, you are referring to this support document. iOS: Wi-Fi settings grayed out or dim
If that is the case, you would need to see about replacing the device. If it is out of warranty, you can see about an out of warranty replacement, which are provided at a reduced cost from a new device.
