I suggest to have it replaced. The warning image you posted is pretty obvious.
Prototype - Not final, in terms of software, it is Beta.
That is why some of your apps are not working properly because the phone itself is not for End-User (Buyer) use, it is for development use only (IMHO).
Edit : Model Number must be either C5503 or C5502, yours really look like a test device model number
Now : Xperia ZR [All Stock]
Previous : Xperia Ray [GB]
