South Korea Smartphone Shipments Slip 0.5% as Premium Devices Take 73% Share

South Korea’s smartphone market shipped 3.78 million units in the first quarter of 2026, dipping 0.5 per cent year-on-year, according to data from IDC Korea.

Handsets priced at $800 and above captured 73.2 per cent of total volume, gaining double digits over the same period last year as buyers gravitated toward top-tier devices.

Persistent inflation, volatile financial markets and geopolitical tension in the Middle East dampened entry-level purchases. Budget and mid-tier devices lost market share despite fresh product rollouts, weighed down by channel inventory accumulated ahead of the new school term.

Foldables Surge as 5G Hits 95% Penetration

Foldable devices led unit expansion during the quarter. Shipments reached 190,000 units, delivering triple-digit percentage growth compared to the opening quarter of 2025.

Fifth-generation network connectivity became standard across nearly the entire market. 5G-capable devices accounted for 95.5 per cent of all smartphone shipments nationwide, supported by steady flagship purchases and a wider spread of affordable 5G models in secondary price tiers.

Direct Sales and Price Hikes Drive Margins

Across East Asia, mature consumer tech markets are splitting along spending lines. Rather than chasing unit volume through discounting, hardware brands in Seoul are steering promotional spend toward high-margin halo models to protect operating profitability against elongated replacement cycles.

Manufacturers plan to lean heavily on flagship releases to generate demand through the first half of 2026, according to Jihae Kang, a researcher on IDC Korea’s mobile phone market research team.

Brands will pursue profitability by raising retail prices on high-capacity storage tiers and expanding direct-to-consumer sales channels through the second half of the year.
