A 17-year-old boy from Canada who built his own phone after his Somalian mother said she couldn't afford to buy him a smart phone has been speaking to the BBC.
Mo Omer – who calls himself a "tech nerd" – built a smart phone from scratch, and says he will sell it at just $180 (£133).
"It's got everything you'd find in a normal phone, it just doesn't cost nearly as much," he told the BBC.
Phones "are not very complicated devices", he added – and says he'd had interest from parts of Africa.
"We've had offers from Nigeria and Algeria and a lot of other places. It's a rapidly growing market that we'd love to get into".
