As someone else has pointed out, talk to Samsung. I don't know where you're based, but they have regional teams that do developer outreach. I've found them to be very helpful.
I'm in Montreal, and will definitely check out regional opportunities! What sort of help did they provide you with? I always imagined it would near impossible for a small, part-time dev to talk to a giant company like Samsung.
You might try touching base with Steve Kondik (@cyanogen; of Cyanogenmod fame) who now works for Samsung. You might briefly explain your project and see if he can get you in touch with the right person at Samsung/Google.
