شاشة iPhone Duo الداخلية فيها خط أو تسمع طقة؟ اعرف السبب وكيف تتصرفiPhone Duo inner screen line or a crunch in the hinge: what it means and what to do

Key terms

Hinge

The metal mechanism in the middle that lets the phone fold. On the iPhone Duo it is a chain of linked joints, like a watch band, kept in step by gears.

Center support bar

A part in the middle of the hinge that supports the screen when the phone is open. It has to drop down when you close it, so the screen can fold over it without pressure.

Cover layer

The flexible polymer layer on top of the inner display, with a matte nano texture finish. Apple designed it to be replaced at a service center.

Pixel row

OLED pixels are wired in rows and columns. A small fault in one connection can affect a whole row or column, which shows up as a long line.

The steps

1. 1

   Step 1

   Know the signs early

   Owner reports collected by iFixit in its teardown (25 October 2026) usually start with a crunch or a pop while opening or closing the phone.

   Then a short line appears along the fold, and a bright line runs across the display.

   The long line is not always a crack travelling through the screen. iFixit explains that a small fault in the connections can affect a whole row or column of pixels.

   Tip: If you see one line, do not press or rub the spot. It can make the damage worse.

2. 2

   Step 2

   Stop folding when you hear an odd noise

   In iFixit's dust test, some powder reached the hinge and it started crunching as the phone opened and closed.

   Some foldable makers give the same advice: if the hinge makes an unusual noise, stop opening and closing it, since grit may be inside.

   Leave the phone in one position, open or closed, until you reach service.

   Tip: Do not clean the hinge with compressed air or a sharp tool. It can push grit further in.

3. 3

   Step 3

   Document the problem

   Take close and wide photos of the line, and a short video of the phone opening if there is a noise.

   Note the purchase date, when the problem started, and roughly how often you folded the phone before it.

   This makes the replacement request faster.

   I have an iPhone Duo with an inner display problem. Here are my notes: [your notes: purchase date, when it started, what the line looks like, any noise from the hinge]. Turn them into short, clear bullet points in time order, with no guesses about the cause, so I can send them to Apple Support.

   Step 4

   Contact AppleCare and ask for a replacement

   On 26 October 2026 Apple said it is aware of an issue affecting the inner display on a small number of iPhone Duo units, and that affected customers should contact AppleCare for a replacement.

   You can reach them through the Apple Support app or book an Apple Store appointment.

   Apple has not announced the cause, so you do not need to prove anything about the hinge. Describe what you saw and heard.

   Step 5

   Do not peel the cover layer yourself

   The matte layer on the inner display is replaceable, but Apple wants it done at service.

   iFixit reports the swap costs $19 with AppleCare+ and $49 without.

   Peeling it yourself can scratch the display underneath, which costs far more.

   Tip: Do not put a third party protector on the inner display.

6. 6

   Step 6

   Keep the fold clean and empty

   Never leave anything between the halves when the phone is closed: a card, a coin, a key or even crumbs. Samsung warns these can scratch or puncture a foldable display.

   The edges have magnets, so keep the phone out of pockets with keys or coins.

   Keep it away from sand and dust as much as you can. The hinge is where grit collects.

   Step 7

   Know the cost before the warranty ends

   According to iFixit, an inner display replacement out of warranty costs $999.

   If you see any of the signs above, do not wait. Open the request now while you are covered.

   If you are about to buy one, consider AppleCare+, since the display and hinge are the most expensive parts to fix.

   Tip: Keep your receipt somewhere easy to find.
