Rii slim bluetooth keyboard issues
Forgive me this is my first post, so I hope I don't break any rules.
I'm a big fan of the Rii slim keyboard and have used it with the iphone quite successfully. However, recently my keyboard broke and I ordered a new one. The control key works, in that it flashes, but none of the functions. I don't know why this is, I know the keyboards have been updated to bluetooth 4. and I'm using this with the iphone5c. It is frustrating beyond belief. I'm wondering if anyone can shed some light on this.
I would appreciate some help.
A little more info on the control key:
I use it to jump to top and bottom of pages and websites, checking time and date, accessing the notification centre etc and now I can't.
I was recently told to change the keyboard to US keyboard and I think I did this and didn't work, any of you clever people know anything, I'd really appreciate your help
