API error 4202 on mobile devices

Hey Guys,

I'm getting an API error 4202 when trying to register via a mobile phone. If try I register via a computer or a tablet with my facebook account, it works fine.

I googled for some solutions, but all I got is this:
https://developers.facebook.com/bugs/507406422635550?browse=search_511bd57f912f84e18364257

Anybody some ideas or suggestions?
Cheers,

Ronald
