Price: Unofficial ৳3,16,000 · iOS 27 · Apple A20 Pro · 5G · NFC · Fingerprint (side-mounted Touch ID)
Apple’s first foldable iPhone is here, and it is the most expensive iPhone Apple has ever sold. The iPhone Duo opens like a book into a 7.6-inch display — Apple’s largest iPhone screen ever — and folds down to a compact 5.4-inch outer display that Apple says covers 90 percent of the screen area of an iPhone 18 Pro. It went on sale on 23 October 2026, and demand immediately outran supply: pre-orders sold out, walk-in stock at Apple Stores was described by Apple as “limited”, and new online orders were pushed back to January 2027.
There is also an important warning for early buyers. Within days of launch, a small number of owners reported the inner display failing along the hinge — bright lines, a dark point at the fold, sometimes after only a few hours of use. Apple has acknowledged the problem affects “a small number of iPhone Duo units” and tells affected owners to contact AppleCare for a replacement. There is no recall. We cover what is known below, because at this price, buyers in Bangladesh — who will be buying imported, unofficial units with no Apple Store nearby — need to know about it before they spend.

Important: the inner-display reports (news, October 2026)
Shortly after the 23 October launch, owners in Australia, China, the US and Canada posted photos of the same failure: a dark point at the hinge, a thin line along the crease, and a bright horizontal line across one half of the inner screen, sometimes after hearing a crunching sound while unfolding. Early counts put the number at around a dozen unique cases. Apple said on 26 October 2026 that it is “aware of an issue impacting the inner display on a small number of iPhone Duo units” and that affected users should contact AppleCare for a replacement; it said most units are not susceptible and the defect tends to show up quickly. Apple has given no cause, no count, and no repair programme. Repair specialist iFixit’s teardown points to the hinge as the likely culprit. Separately, Apple lists an out-of-warranty inner-display repair at $999 — about half the phone’s starting price — according to CNBC’s reporting. Some images circulating online have also been flagged as fake, so the true scale is still unclear. Our advice: if you buy an imported Duo in Bangladesh, test the inner display thoroughly in the first days, keep the purchase receipt, and confirm with the seller in writing what warranty, if any, covers the folding screen.
Variants & Colors
4 variants (all with 12GB RAM):
- 12GB + 256GB — US $1,999; India ₹2,99,900
- 12GB + 512GB — US $2,199; India ₹3,24,900
- 12GB + 1TB — US $2,599; India ₹3,74,900
- 12GB + 2TB — US $3,199; India ₹4,49,900
2 colors: Star White and Night Sky. Both use the same grade 5 titanium enclosure with a mirror-polished finish, and both cost the same at every storage tier.






Apple iPhone Duo Price in Bangladesh November 2026
Apple has not launched the iPhone Duo officially in Bangladesh, so there is no official Bangladesh price. The phone is expected to reach Dhaka shops as an unofficial import. The unofficial listing price is ৳3,16,000 for the 12GB + 256GB base model (GSMArena Bangladesh listing). For comparison, the official US price is $1,999 (≈ ৳2,43,878 at 1 USD ≈ 122 BDT) and the India price is ₹2,99,900 — so expect the Dhaka street price to move with import supply, and to be higher while global stock is short (new Apple Store orders were already slipping to January 2027). Treat the figure below as an expected/unofficial price, not a fixed shop price.
| Model | Price | Display | RAM | Storage | Released |
|---|---|---|---|---|---|
| Apple iPhone Duo (12GB + 256GB) | ৳3,16,000 (Unofficial) | 7.6" foldable OLED + 5.4" cover | 12GB | 256GB | 23 Oct 2026 |
| Apple iPhone Duo (12GB + 512GB) | — (Unofficial, varies by shop) | 7.6" foldable OLED + 5.4" cover | 12GB | 512GB | 23 Oct 2026 |
| Apple iPhone Duo (12GB + 1TB) | — (Unofficial, varies by shop) | 7.6" foldable OLED + 5.4" cover | 12GB | 1TB | 23 Oct 2026 |
| Apple iPhone Duo (12GB + 2TB) | — (Unofficial, varies by shop) | 7.6" foldable OLED + 5.4" cover | 12GB | 2TB | 23 Oct 2026 |

- Design — 9/10: A 5.2 mm-thin unfolded body in grade 5 titanium with a precision hinge is genuinely impressive engineering.
- Display — 9/10: Two bright 120Hz LTPO OLED panels with 3,000-nit peak brightness and a nano-texture finish that minimises glare; one point off for the early inner-display failures and the visible crease.
- Performance — 10/10: The 2 nm A20 Pro is Apple’s flagship chip, built for Apple Intelligence and the new Siri AI.
- Camera — 7/10: Two strong 48MP cameras, but no dedicated telephoto lens — the 2x zoom is cropped from the main sensor, which is a real gap at this price.
- Connectivity — 9/10: 5G (Sub-6 and mmWave on the US model), Wi-Fi 7, Bluetooth 6.0, NFC, Ultra Wideband (gen2) and satellite SOS.
- Features — 9/10: Split View multitasking, Apple Pencil (USB-C) support, Touch ID in the side button, IP68, and a reimagined iOS 27.
- Battery — 7/10: All-day claims are strong (44 hours video on the outer screen), but the 4,883 mAh cell is small for a folding tablet-sized device and charging wattage is unpublished.
- Usability — 7/10: A brilliant large-screen experience held back by the hinge concern, the 254 g weight, and the January 2027 wait for new orders.
These scores are based on published specifications and launch reporting only. We have not tested this phone hands-on.
