How come my iphone won't let me take pics?

So i just bought more i cloud storage (i have 15G now) and i still can't take pictures or download aps. There's 11G avaliable so why can't i take pictures or download things if i DO have th memory?

Go back to the vender who sold you the cell.
Sounds like you're missing an update.

You should talk to Apple. Or go on Apple Discussions.
