Galaxy Z Fold 8 sales rise after iPhone Duo launch in Korea
Galaxy Z Fold 8 sales in South Korea rose roughly 10% week-over-week in the seven days after Apple unveiled the iPhone Duo on Sept. 10, according to telecommunications-industry sources cited by Yonhap News Agency. That number is fueling a wave of "Galaxy Z Fold 8 sales rise after iPhone Duo launch" headlines this week, but the framing needs a correction up front: Apple has only unveiled the iPhone Duo in Korea. Pre-orders don't open until Oct. 16, and retail sales don't begin until Oct. 23, per EDAILY.
That distinction matters for anyone in South Korea actually deciding between the two foldables. This week's bump reflects reaction to an announcement, not a head-to-head purchase between two phones sitting on the same store shelf. It's also a domestic telecom-sales estimate, not evidence of a broader or global shift toward Samsung's foldable.
What Galaxy Z Fold 8 sales in South Korea actually show
The 10% figure traces to unnamed telecommunications-industry sources, and it shows up in nearly identical form across Yonhap, Korea JoongAng Daily, MK, and EDAILY. Multiple outlets attribute the estimate to telecommunications-industry sources, which suggests shared reporting rather than four separate confirmations of the same number.
None of the coverage includes actual unit-sales totals, the prior week's baseline, which storage configurations moved, or whether Samsung ran any promotions during that window. That gap makes it hard to judge how meaningful "about 10%" really is in commercial terms based on what's been published so far.
Industry sources told MK that some buyers had delayed a purchase while waiting to see Apple's foldable, then switched to the Galaxy Z Fold 8 once the reveal landed. That's a plausible read of the bump, but it comes from the same industry-source pool driving the headline number, not from surveyed buyers or retailer data.
There's a separate figure worth keeping apart from all of this. The Galaxy Z8 series, which includes the Fold 8, Fold 8 Ultra, and Flip 8, had already logged 1.44 million pre-sales in Korea before Apple's unveiling, and continued selling afterward, according to MK. That number covers the entire lineup launched back in August, not the Fold 8 alone, so it can't isolate how much of the reported increase belongs to the Fold 8 specifically.
Because the iPhone Duo won't be purchasable in Korea until Oct. 23, this week's numbers capture comparison shopping and anticipation rather than a real competitive conversion. Whether the bump holds, fades, or reverses once Apple's foldable actually reaches Korean retail is still unknown.
Korea's unusually wide price gap between the two foldables
Price shows up most often in the reporting as a factor behind the shift, though sources describe it as something Korean buyers "consider," not a proven cause of the increase. The 256GB iPhone Duo carries a Korean price of 3.29 million won, compared with 2.2781 million won for the 256GB Galaxy Z Fold 8, a gap of roughly 1.0119 million won, or about $725, according to Yonhap and EDAILY.
That gap looks unusually wide next to the U.S. market, where the same 256GB models differ by only about $100, per Korea JoongAng Daily and MK. At the top end, the 2TB iPhone Duo is priced at 5.09 million won, which MK describes as the most expensive iPhone Apple has ever sold.
Samsung is leaning into the moment publicly rather than staying quiet about it. The company is running outdoor ads reading "Welcome to Foldable" in Seoul's Gwanghwamun and COEX districts, according to MK, a sign it's treating Apple's arrival as a foldable-category win worth advertising against rather than a threat to downplay.
None of the sourcing ties the price gap directly to the reported 10% increase through actual transaction data. It's listed alongside hardware specifications as a factor Korean buyers weigh, per Yonhap, not as a confirmed driver of the sales shift.
How the two foldables compare on paper
Specs are worth laying out here as background, not as an explanation. Nothing in the available reporting shows that hardware or software differences caused this week's reported increase.
The iPhone Duo weighs 254 grams, which both MK and EDAILY report is 53 grams heavier than the Galaxy Z Fold 8. Folded, the iPhone Duo measures 11.3 millimeters thick, though the two outlets disagree on exactly how that compares to the Fold 8's own folded thickness, so that specific delta isn't reliable enough to publish here.
On software, the iPhone Duo offers a two-app split-screen view, while the Galaxy Z Fold 8 can display up to three apps at once with resizable windows and pop-up switching, per EDAILY. MK also describes the Fold 8's 4:3 display ratio as balanced, comparing its proportions to a passport, though that's MK's characterization of the design, not independent testing, and it isn't evidence that screen shape swayed any of the buyers behind this week's reported numbers.
Supply could complicate any near-term comparison regardless of spec preferences. Counterpoint Research analyst Liz Li said supply is likely to be tight in the iPhone Duo's early stages, telling EDAILY that sales and deliveries are more likely to expand market by market than launch everywhere at once. If that pattern holds, Korean stock could stay limited even after sales officially start on Oct. 23.
What's confirmed, what's not, and what to watch before Oct. 23
What's confirmed: Korean telecommunications-industry sources report a roughly 10% week-over-week increase in Galaxy Z Fold 8 sales following the iPhone Duo's Sept. 10 unveiling, per Yonhap. What isn't confirmed: actual unit volumes, the specific cause of the increase, and whether it holds once the iPhone Duo goes on sale in Korea on Oct. 23, per EDAILY.
Samsung's own numbers add a separate layer worth keeping apart from the Korea-specific figure. The company reported more than 30% pre-order growth for the entire Galaxy Z lineup compared with the previous generation, tied to the global rollout that began Aug. 5, according to Samsung Global Newsroom. That's a company claim about worldwide pre-orders across the whole lineup, not independent proof of Fold-8-specific demand inside Korea.
For now, treat this week's figures as an early reaction to an announcement rather than a settled verdict on how Korean buyers will choose between the two foldables. The more meaningful test arrives once the iPhone Duo actually reaches Korean retail on Oct. 23, when confirmed local pricing, real stock availability, and independent reviews replace anticipation with an actual purchase decision. Anyone weighing a foldable purchase in Korea right now should hold off reading this week's 10% figure as anything more than a preview.
