WCF Client Problems in Release Mode?

I have a WCF service stub placed in a PCL library project used in an Android app I'm developing. It works fine in debug mode. I can call the WCF service just fine. It also works just fine in the iOS version of the app (both debug and release). However, when I try to call the WCF service in Android while in release mode it throws exceptions. The only info I have found on the Internet is to check that Internet permissions are set for the app. They are. Has anyone else run into this?
