Global smartphone shipments fell 20% year on year in 3Q26, according to preliminary estimates from Omdia, as rising memory and storage costs squeezed vendors and accelerated a downturn that began earlier in the year.
Omdia said the decline was a sharp acceleration from the 6% year-on-year fall recorded in the previous quarter. Shipments also declined sequentially, despite new flagship launches and channel preparations for year-end demand, with vendors scaling back low-margin device volumes as component costs constrained pricing flexibility.
The research firm said the contraction is contributing to a more polarised competitive landscape. Samsung and Apple together accounted for 45% of global shipments in 3Q26, up about eight percentage points from a year earlier, as mass-market-focused vendors experienced steeper declines amid profitability pressures.
Samsung remained the largest vendor by shipments, with a 23% market share in 3Q26, up from 19% in 3Q25. Omdia said Samsung gained share despite a year-on-year decline in shipments, citing its broad portfolio and global channel presence, as well as the August launch of the Galaxy Z Fold8 and Flip8 series supporting its premium positioning.
Apple ranked second with a 22% market share, up from 18% a year earlier. Omdia attributed Apple’s performance to continued demand for the iPhone 17 family and the September introduction of the iPhone 18 Pro and Pro Max. The firm also pointed to Apple’s entry into foldable smartphones with the iPhone Duo, and said AI features were not yet a major purchase driver for consumers, though “Apple Intelligence” could become more important in differentiating user experience over time.
Xiaomi held third place with a 12% share in 3Q26, down from 14% in 3Q25, followed by OPPO (including realme and OnePlus) at 9% (down from 12%) and vivo at 8% (down from 9%). “Others” accounted for 27%, down from 29%.
Omdia said rising memory costs are pressuring profitability across price segments, with a pronounced impact in price-sensitive categories, leading vendors to reassess entry-level portfolios and make more selective decisions about positioning, pricing and market coverage. The company said vendors are increasingly prioritising average selling price growth and portfolio optimisation to protect profitability.
“Rising component costs and differing vendor responses are reshaping the competitive landscape, but market share alone does not tell the full story,” said Hayden Hou, Principal Analyst at Omdia. “As vendors make different trade-offs between shipment scale, revenue and profitability, their performance needs to be assessed beyond unit shipments. More importantly, the strategic decisions made during this downturn could have lasting implications beyond the current cost cycle. Investments in new channel partnerships, device financing capabilities and stronger premium portfolios will help determine which vendors emerge with a more competitive and sustainable business model once cost pressures ease.”
Lucas Zhong, Senior Analyst at Omdia, said the challenge is especially acute for vendors competing primarily on affordability and for those focused on emerging markets where consumers are more price-sensitive. Zhong warned that cutting shipments to protect margins can carry longer-term risks, including reduced brand and channel presence.
Looking to 4Q26, Zhong said new flagship launches, promotions and seasonal demand were unlikely to fully offset “persistent supply-side pressures”, adding that vendors may need to combine tighter inventory management with financing, trade-in and telco partnerships to support upgrades without broad discounting.
Omdia noted its figures are preliminary and subject to change on final release. The market share estimates are based on sell-in shipments and include Redmi and POCO within Xiaomi, iQOO within vivo, and realme and OnePlus within OPPO.
