The iPhone Duo asks developers to support one aspect ratio, open or closed
ZDNET's foldable reviewer puts the Duo's $1,999 price in line with the market and the crease close to invisible. The one thing a product team can act on ahead of hardware is that the screen keeps its proportions folded or open.

What happened
- The Duo carries a full IP68 water and dust rating, short of the Honor Magic V6, which ZDNET notes holds both IP68 and IP69.
- ZDNET reports the crease is impressively hard to see but still visible at certain angles, with a nano-texture finish helping hide it and making the screen matte.
- The ZDNET columnist wrote the assessment without hands-on time, working from Apple's presentation and captured videos of demos.

Why it matters
- constraint Anyone budgeting Duo repairs or an extended warranty is working from an ingress rating and nothing about the hinge, since ZDNET's reviewer leaves long-term durability open and quotes no cycle figure.
- decision App teams get to decide whether the extra area is worth designing for at all, because the matched aspect ratio means they are not being asked to build and maintain a second layout.
- precedent ZDNET's reviewer expects Motorola and Samsung follow-ups to move to IP68. A buyer specifying foldables next cycle can hold out for water resistance as standard.
- exposure Moving UI controls to the right edge puts palm rejection in the support queue, and the open question comes from a reviewer with four years of foldables who has not yet held the device.
The aspect ratio is the line in ZDNET's account that a software team can put on a sprint board. Apple gave the Duo the same proportions closed and open, and ZDNET's columnist wrote that "it was smart to give the phone the same aspect ratio when closed and open, easing the burden on developers" [14]. A layout built for that proportion scales to the larger panel, and it is the only layout the team has to draw and maintain.
The price is the settled part. At $1,999 the Duo lands $501 under the $2,500 figure ZDNET says was predicted for an Apple foldable and $1,001 under the $3,000 one [5]. ZDNET calls that in line with most other foldables on the market, and notes the Galaxy Z Fold 8 Ultra costs more than the Duo [2][3].
Durability is the unsettled part. What Apple shipped is a full IP68 water and dust rating [6], which the columnist called "absolutely critical in today's foldables" [7]. He also wrote that "this is a first-generation product, so it remains to be seen how durable this phone will be long-term" [8]. IP68 is an ingress rating. The column carries no fold cycle count and no repair figure [22].
By ZDNET's own timeline, the crease work is catch-up: the Oppo Find N6 and then the Galaxy Z Fold 8 shipped this year with basically no crease [13]. Apple's is still there and visible at certain angles, per ZDNET, which reports it is impressively hard to see [11]. A nano-texture on the screen helps hide it and gives the panel a matte finish [12].
The reviewer put his own open question in print. Apple moved UI elements to the right side of the phone [15], and of that he wrote: "I have to wonder how those UI elements will handle palm rejection." [16] He has not held the device and was working from Apple's presentation and captured videos of demos [17], after four years of using every foldable launched in the U.S. [18]
Whether the app gains anything from more area at the same proportions is a design question, and it can wait until units exist. Whether the app breaks when the screen changes size mid-session is a bug class, and it can be tested this week on anything that resizes a window. Both are independent of the $1,999. ZDNET's list of what it still does not know ends on the camera [19].
What to watch
- Hands-on reviews or teardowns that put a fold cycle count and a repair price against the IP68 rating.
- Whether the next Motorola and Samsung foldables ship IP68, as ZDNET's reviewer expects them to.
- Whether Apple documents the right-edge UI placement and its palm rejection behaviour for third-party developers.
