Back in 2017, Apple went all out, removing the Home button and replacing it with Face ID and the TrueDepth camera system. In hindsight, the iPhone X was the first iPhone to radically alter its front design in a way no other device has replicated since. Now there's a rumor the iPhone 18 Pro might take another swing at that idea, moving some Face ID hardware beneath the display instead of a notch or Dynamic Island.
Nothing's confirmed. However, under-screen Face ID could well be the next big move toward a cleaner display. Either way, a solid smartphone case fit still depends on confirmed dimensions, not early rumors. In this article, we’ll explain what this shift is and what it means for phone cases.
Phone 18 Pro and explain how a cleaner front design could affect case fit, protection, and compatibility.
What Under-Display Face ID Actually Means
Some Face ID components would sit beneath the glass instead of inside a visible cutout. It means you can see less hardware, possibly a smaller front-camera opening.
However, all reports don't fully agree. Some say the Dynamic Island shrinks dramatically; others think it survives in a smaller form. Under-display does not always mean completely invisible. The big question is how much of the front cutout actually changes. Right now, rumors point to a cleaner display, but not necessarily a fully uninterrupted one.
Why This Could Be Apple's Biggest Shift Since iPhone X
Face ID has shaped the front of the iPhone since the iPhone X, and this would be the first real challenge to that shape in years. Worth noting "could be" is doing a lot of work there, on purpose.
A smaller cutout would make the display feel more open. But this would be more of a visual shift than a case-size guarantee. A cleaner front doesn't tell case makers much about the back, the buttons, or the frame.
What We Know vs. What's Still a Rumor
Confined information is rare.
-
Confirmed: Apple hasn't introduced the iPhone 18 Pro, hasn't confirmed under-display Face ID, and hasn't yet provided exact dimensions and layouts.
-
Speculated: Under-display Face ID, reduced or altered Dynamic Island, changed camera cutout, and Pro versions coming before the regular iPhone 18.
It is important to consider rumors; however, they aren't dimensions, so case choices must be based on the model's official specifications.
How a Smaller Dynamic Island Could Affect Cases
Mostly a front-screen story, not an outer-frame one, but it still matters for cases with screen protection, folio covers, or bezels sitting close to the display edge.
Front design changes can affect more than the screen, since case makers have to steer clear of sensors, the camera opening, and speakers. A case should protect the edges without crowding the display, and raised bezels need to work with the final screen layout.
Why the Back of the Phone Still Decides Case Fit
Under-display Face ID gets attention because it's new and visible. But from generation to generation, the rear camera layout is usually what breaks case compatibility.
The front may get the headlines, but the back still controls case fit. Camera cutouts leave no room for guessing, and a case that almost fits is not good enough.
Screen and Edge Protection Matter More Now
If the cutout shrinks, the screen feels bigger and more open, which raises the stakes on edge protection rather than lowering them. More screen makes clean edge protection even more important.
The case should protect without making the display feel boxed in. Slim protection matters when the phone design gets cleaner, since a bulky case undercuts the whole point.
Don't Forget Buttons and Camera Control
It's easy to fixate on Face ID and forget the phone has buttons. Shift button size, spacing, or Camera Control even slightly, and an old case stops working.
Button placement matters as much as the display rumor. A premium case should make every control easy to use; do not buy a case based on front-design rumors alone.
Will an iPhone 17 Pro case fit an iPhone 18 Pro?
No. Small shifts in thickness, camera bump size, button position, or MagSafe placement are enough to break the fit entirely.
Almost fitting is not the same as protecting. Do not force a new phone into an old case; model-specific fit is always the safest choice.
Leather Still Makes Sense, Cleaner Screen or Not
Whatever happens up front, daily priorities don't change: grip, protection, comfort, MagSafe, something that feels good to hold.
A cleaner phone design deserves a case that feels equally considered. Full-grain leather adds warmth to advanced technology, and premium protection should feel good every time you pick up the phone.
What to Look For Once the Case Is Real
Fit comes first. Here are a few things to look for:
-
Exact model compatibility.
-
Raised screen edge and camera protection.
-
Clear sensor and speaker clearance.
-
Real button and Camera Control access.
-
MagSafe. Slim profile.
-
Good lining.
-
Full-grain leather.
-
A wallet option, if you want one.
Premium is in the details around the edges, buttons, and camera, and the right case should protect the new design without hiding what makes it feel new.
Mistakes Worth Avoiding
Treating under-display Face ID as confirmed. Buying before real dimensions exist. Assuming an iPhone 17 Pro case carries over. Ignoring the back of the phone because the front got the attention. Grabbing a cheap early listing. Choosing something bulky enough to hide the point of a cleaner design.
Early does not always mean accurate. Do not guess where fit matters. A good case should support the new design, not work against it.
FAQs
Will the iPhone 18 Pro have under-display Face ID?
It is rumored, but Apple has not confirmed it. Reports suggest some Face ID components may move beneath the display, potentially reducing the Dynamic Island.
How could under-display Face ID affect iPhone cases?
The biggest impact would be on raised bezels, folio covers, and sensor clearance near the display. Final case fit will still depend on the phone’s confirmed dimensions.
Will an iPhone 17 Pro case fit the iPhone 18 Pro?
Do not assume it will. Changes to the camera housing, buttons, thickness, frame, or MagSafe alignment could make the older case incompatible.
Protect the Next iPhone Without Compromising the Design
Under-display Face ID for the iPhone 18 Pro may prove to be Apple's biggest redesign since the iPhone X, but it would be wise to rely on proven case compatibility rather than speculation.
