(AP) North Korea's announcement that it is mass producing a home-grown smartphone has been met with skepticism in the tech industry.
The North's state media last week showed leader Kim Jong Un inspecting "Arirang" phones at a Pyongyang factory.
Technology writer Martyn Williams says the phone is probably manufactured in China.
North Korea has promoted the development of science and technology as a means to improve its moribund economy. It says it developed a tablet computer last year.
South Korean computer experts say North Korea is strong enough in software technology to have launched cyberattacks that disrupted banking and government websites in South Korea.
North Korea has mobile phones and an Intranet but they are walled off from global networks.
