In just two years, over 20 million South Koreans, or about 40 percent of the total population, have purchased smartphones, one of the fastest adoption rates in the world.
But there have been complaints by customers over after-sales policies and a delay of software upgrades from foreign firms compared to their domestic rivals in a nation which boasts over 94 percent Internet literacy.
The Korea Consumer Agency (KCA) said it mediated 910 consumer complaints over handset-related issues, filed with it during the January-September period.
This was up from 558 cases the government organization saw a year earlier.
