Hello,
I used the duid device information and got value on the simulator when comes to emulator or real device getting a null value for the duid.
webapis.productinfo.getDuid()
webapis.productinfo.getRealModel().
same for the real model also.
Since no one responded, I would suggest you look for an answer in the FAQ-Q/A under the most appropriate topic on the Smart TV Seller Office site If you don’t find a solution there then sign in and open a Smart TV Seller Support Request . They can help you better there.
