Congratulations! The G650 X are forgotten gems...
You could start with checking the two sticky threads in
the Android subforum out. If your phone is in either, you pretty much know.
If it isn't in either thread then one idea could be to reveal here what phone you have. Maybe someone already use it, or at least have it and can test it for you?
The third thing I would try would be to ask here or elsewhere if there's anyone close to you that have a GS911 blu, and that will allow you to test with it. I'm in the greater Stockholm area should you have an opportunity to come to Sweden.
The fourth alternative would be to change or get an additional phone for this purpose from the known good list.
