iPhone 18 Pro Max: 5 BIG Problems Users Are Reporting — Before You Buy, WATCH OUT!

How this guide was compiled: This is a research-based problem tracker and buying guide, not a sponsored review. Every issue below is attributed to owner reports, Apple’s own statements, or reporting by Notebookcheck, Mashable, MacRumors, NDTV, News18, PCMag, PhoneArena, Lifehacker, Beebom, Digit, Indian Express and Gizbot. The iPhone 18 Pro Max has been on sale in India since September 18, 2026, and Apple has already shipped iOS 27.0.1. We have separated what Apple has fixed from what it has not. If a problem is anecdotal or unconfirmed, we say so plainly.

Quick Answer

iPhone 18 Pro Max problems in 2026: The five biggest issues are AT&T cellular failures on US units that need a hardware replacement, green line display defects, Face ID crash reboots (mostly fixed in iOS 27.0.1), speaker popping and crackling that survives a replacement, and build quality defects including camera-ring discoloration and back glass not sitting flush. India price starts at ₹1,79,900. Buy the India unit, install iOS 27.0.1, and inspect before you leave the store.

Let’s be blunt. The iPhone 18 Pro Max is a brilliant phone on paper. The A20 Pro is the fastest chip Apple has ever shipped, the 48MP variable-aperture camera is genuinely new, and the battery finally feels like a two-day battery. Beebom gave it an 8.5/10 and called it “Apple at its most complete.”

But something unusual is happening around this launch. Five weeks after the September 18 sale date, owners are still reporting problems that range from mildly annoying to genuinely serious. Some are software bugs that Apple has already patched. Others — particularly the speaker crackle, the camera-ring discoloration, and the green line display defects — have no public fix, no official explanation, and in some cases, a replacement unit behaves the same way.

If you are spending ₹1,79,900 on the base model and up to ₹3,29,900 on the 2TB version, you deserve to know exactly what you are walking into. This guide breaks down the five biggest iPhone 18 Pro Max problems users are reporting, what Apple has done about each one, which issues affect India and which do not, and the checks you must run before you hand over your card.

We are not telling you to avoid the phone. We are telling you to buy it with your eyes open — and to inspect it like you mean it.

Why this matters right now: The iPhone 18 Pro Max went on sale in India on September 18, 2026, at ₹1,79,900. Apple released iOS 27.0.1 on September 28, which fixed three bugs but not the speaker, build quality or camera-ring complaints. If you are buying this week, you are buying into a launch that is still settling. The next few iOS updates will decide whether the remaining issues are software or hardware.

Key Takeaways

  • AT&T SOS failures are confirmed by Apple and require a full hardware replacement on affected US units; India models use Apple’s C2 modem and have no confirmed cases
  • Green, pink and red vertical display lines are reported in India and other markets, but some viral images appear to be fake — persistent lines are more likely hardware-related
  • Face ID crash reboots were largely fixed in iOS 27.0.1, but some users still report authentication struggles with thick screen protectors
  • Speaker crackle and popping remains unresolved, and some replacement units make the same noise
  • Build quality defects include back glass that is not flush with the frame and pink discoloration around the camera plateau on burgundy and black models
  • India price runs from ₹1,79,900 to ₹3,29,900; the phone weighs 249g and is 8.75mm thick
  • Out-of-warranty screen repair costs ₹42,900 in India, which makes warranty coverage and pre-purchase inspection critical

Quick Verdict: Is the iPhone 18 Pro Max Worth ₹1,79,900?

What’s Genuinely Great

  • A20 Pro is class-leading and stays cool in long gaming sessions
  • 48MP variable-aperture camera is a real creative tool
  • Around 10 hours of screen-on time and two-day battery life
  • 6.9-inch 120Hz display with 3,000 nits peak brightness
  • Industry-leading video quality and ProRes RAW support
  • Louder, clearer speakers when they are not crackling
  • Five years of iOS updates and strong resale value

What’s Worrying

  • 249g and 8.75mm — Apple’s heaviest iPhone
  • Speaker crackle has no confirmed fix
  • Camera-ring discoloration on burgundy and black
  • Green line display reports persist despite being partly fake
  • US-only AT&T failure shows launch QA gaps
  • Build quality issues with back glass and paint peeling
  • ₹42,900 out-of-warranty screen repair cost

The one-line answer: The iPhone 18 Pro Max is still the best iPhone for video, battery life and raw performance, but this is a launch you should inspect carefully. Install iOS 27.0.1 immediately, test the earpiece at full volume, check the camera rings, display and frame under daylight, and buy the India unit with local warranty — not a US import. If you want zero drama, the Galaxy S26 Ultra at ₹1,39,999 is the safer long-term pick.

Problem 1: The Cellular Failure That Turns Your Phone Into an iPod

This is the most serious issue reported so far, and it is also the one Indian buyers can mostly ignore — if they buy the right unit.

Starting September 19, a day after the phone went on sale, a small number of iPhone 18 Pro Max owners on AT&T in the United States reported that their phones dropped into SOS mode and lost mobile service completely. No calls, no messages, no mobile data. AT&T’s own alert warned that some phones might be unable to complete calls, texts or data, including calls to 911.

Apple confirmed the fault on October 2. The company said iOS 27.0.1 and an AT&T carrier settings update are “meant to help prevent this issue from occurring,” but phones that had already lost service needed to be replaced entirely. Apple has not said what fails inside the phone, and it has not added a repair programme to its support list. Notebookcheck reports that the issue is a hardware problem in a small number of US Pro Max units.

Why This Happened — and Why India Is Different

The US iPhone 18 Pro Max is the only model in the lineup that uses a Qualcomm modem. Every other iPhone 18 model, including the India variant, uses Apple’s own C2 modem. Mashable reports that this makes the Qualcomm modem the prime suspect, although Apple has not officially blamed it.

For Indian buyers, this is the single most important takeaway: buy the India unit, not a US import. The AT&T issue has not been reported on India’s Airtel, Jio or Vi networks, and the India model uses different modem hardware. A grey-market US Pro Max may look cheaper, but it can carry this fault, may not support Indian carrier aggregation properly, and will almost certainly face warranty friction. Notebookcheck notes there are currently no indications that the issue occurs in Europe or other regions outside the US.

What to do if you already own a US import: Install iOS 27.0.1 and check for a carrier settings update under Settings → General → About. If the phone has already lost service, software will not bring it back — contact Apple or your carrier for a replacement. If you are in India, visit an Apple Authorised Service Provider with your proof of purchase and expect the warranty to be reviewed against the country of original sale.

The AT&T service-loss issue affected a small number of US iPhone 18 Pro Max units and required a hardware replacement. India models use Apple’s C2 modem and have no confirmed cases.

Problem 2: The Green Line Display Defect That Won’t Go Away

This is the issue with the most confusing evidence. Some reports are real. Some are not. And the ones that are real point to a hardware fault that a reset will not fix.

Since launch, iPhone 18 Pro and Pro Max owners have posted photos and videos of green, pink and red vertical lines running down their displays. NDTV reports that similar complaints have surfaced in India and other markets, with some users claiming Apple replaced their phones after they reported the issue. News18 adds that one user said even a full reset of the phone did not fix the line.

Why Some of the Viral Evidence Is Fake

Not every viral image is genuine. A widely shared photo shows a green line passing behind the Wi-Fi icon in the status bar. As Reddit users and ARY News flagged, that is not how a real display defect behaves — a faulty panel would draw the line over or under the UI, not weave behind an icon. At least one of the videos is therefore likely to be software manipulation or a different issue entirely.

How to Tell If Yours Is Real

The practical test is simple: take a screenshot. If the line appears in the screenshot, it is likely a software rendering bug. If the line does not appear in the screenshot but is visible on the screen, it is almost certainly a hardware fault in the display panel or its driver. Persistent green or pink lines that survive a force restart and an iOS update point to hardware.

India warranty reality: A genuine display defect should be covered under Apple’s one-year India warranty. Out-of-warranty screen replacement for the iPhone 18 Pro Max costs ₹42,900, so do not wait until the warranty window closes to report a line. If the line is present at unboxing, photograph it, keep the invoice, and raise a ticket with Apple Support the same day. Amazon India lists a 10-day service centre replacement window for defective items, so act fast if you bought online.

Problem 3: The Face ID Crash That Made People Think Their Phone Was Dead

This one looked scary. It is also the clearest example of a launch software bug that Apple fixed quickly — mostly.

Within days of launch, owners reported that when Face ID failed inside a protected app — Passwords, Wallet, a locked photo album, a banking app, or a private Safari tab — the phone froze, stopped responding to touch, and then rebooted on its own. MacRumors documented the issue on September 21, noting that the device would freeze and eventually reboot to the lock screen. After the restart, diagnostic logs showed panic-full entries, which are low-level kernel crash reports.

Apple released iOS 27.0.1 on September 28, 2026, and the release notes confirmed the fix. The same update also fixed a 2x camera colour artefact at f/1.48 and a touchscreen freeze triggered by opening Notification Centre and Control Centre together.

What Apple Didn’t Fix

Some users still report authentication struggles, especially with matte or privacy screen protectors. Apple moved the Face ID flood illuminator beneath the display to shrink the Dynamic Island, which made the module more sensitive to thick films that scatter infrared light. Some MacRumors forum members also reported “Face ID is Not Available” setup messages and cases where the “Require Attention” setting was not respected.

Test it before you leave the store: Set up Face ID, then open Passwords or Wallet and deliberately fail a scan. If the phone freezes or restarts, you are on an old iOS build or you have a faulty unit. Install iOS 27.0.1 first, then test again. If Face ID fails repeatedly, remove any screen protector before assuming the phone is faulty.

Sources: MacRumors, Oman News Agency (iOS 27.0.1 release notes), and Mac OTAKARA (screen protector interference).

The Face ID reboot bug was triggered by a failed scan inside protected apps. iOS 27.0.1 fixed the crash on September 28, 2026.

Problem 4: The Speaker Popping That Survives a Replacement

This is the issue that worries us most, because Apple has not said a word about it and a replacement phone may not solve it.

Since around September 20, iPhone 18 Pro and Pro Max owners have described a clicking, popping, ticking or crackling sound from the earpiece — and in some cases the bottom speaker as well. Some hear it during calls. Others hear it when a notification arrives, when the keyboard appears, while scrolling a website, or when toggling Airplane Mode on and off. MacRumors reports that adjusting screen brightness quickly can also trigger it.

iOS 27.0.1 did not fix it. Mashable reports that the update did not resolve the audio problem for some users, and at least one owner exchanged their iPhone for a new one only to discover that the replacement phone had the same exact problem.

Is It Software or Hardware?

Nobody knows for sure. One Apple Store employee reportedly told a customer it was “most likely a software issue that would be fixed with an update,” but that update has not arrived. A second phone with the same crackle points toward software, but Apple has not confirmed the cause. It could be an audio processing bug, a driver issue, or a hardware fault in the earpiece assembly. Until Apple comments, treat it as unresolved.

Test it before you leave the store: Make a call at full volume, play a notification sound, open and close the keyboard, toggle Airplane Mode, and change brightness quickly. If you hear a tick, pop or crackle, ask for another unit before you walk out. In India, the standard Apple warranty covers manufacturing defects, but intermittent audio issues can be harder to prove after the return window closes.

Sources: Mashable, MacRumors, PhoneArena, and Notebookcheck.

Problem 5: The Build Quality Defects Nobody Expected on a ₹1.8 Lakh Phone

This is not a single bug. It is a cluster of cosmetic and build issues that have appeared on a phone that costs more than a used hatchback.

5a. Pink Discoloration Around the Camera Plateau

Owners of burgundy and black iPhone 18 Pro and Pro Max units have posted photos of pale, pinkish or lighter rings around the rear camera lenses. Some say the marks were visible right out of the box. Others say they appeared after a few days of use. One widely shared post claimed even display units in an Apple Store had the marks. Vietnam.vn reports that the discoloration is most noticeable around the camera module on burgundy units, and some cases are considered more serious when the colour shift spreads to the rest of the body.

Experts quoted by Vietnam.vn suggest the cause may be Apple’s switch from titanium to aluminium alloy for better heat dissipation. Aluminium is softer and its anodised finish is more prone to wear and fading under friction. Ultraviolet light exposure is another hypothesis, based on owners who noticed the change after using their phones outdoors. None of this is confirmed by Apple.

5b. Back Glass That Isn’t Flush

Some owners report that the back glass panel is not perfectly flush with the frame, creating a slight lip or gap. This is a fit-and-finish issue that can affect water resistance over time and is worth checking at unboxing. If the gap is visible or you can feel it with a fingernail, raise it immediately.

5c. Paint Peeling on the Frame

PhoneArena has documented a case where a burgundy iPhone 18 Pro Max developed paint wear on the corners after only about two weeks of normal use, exposing a different colour underneath. This is consistent with the softer aluminium frame theory and is exactly the kind of cosmetic defect that is hardest to prove as a manufacturing fault after the return window closes.

Your warranty leverage: If the marks or gaps are present at unboxing, photograph them immediately, keep the box and invoice, and raise a ticket with Apple Support the same day. A manufacturing finish defect should be covered under the standard one-year India warranty. If the marks appear later, document the date and avoid harsh cleaners — Apple’s guidance says not to use bleach or hydrogen peroxide on an iPhone.

Status of Fixes: What Apple Has Fixed vs What It Hasn’t

This table is the fastest way to understand where the iPhone 18 Pro Max stands as of October 23, 2026. It separates software fixes from hardware problems and unconfirmed reports.

Apple’s software updates — primarily iOS 27.0.1 — have addressed the minor bugs: the Face ID crash, the 2x camera artefact, and the touchscreen freeze. For severe issues like the AT&T cellular failure and genuine vertical display lines, users are advised to contact Apple Support for a device replacement, because these are identified as manufacturing or hardware-related faults that software cannot repair.

India Buying Checklist: 8 Checks Before You Pay

If you are buying the iPhone 18 Pro Max in India this week, run through this list. It takes ten minutes and can save you months of frustration.

1. Confirm It Is the India Unit

Check the model number and the box language. The India variant uses Apple’s C2 modem and carries local warranty. Avoid a US import, especially if the seller cannot show an India invoice.

2. Install iOS 27.0.1 Before You Judge Anything

The Face ID reboot, 2x camera artefact and touchscreen freeze are fixed. If the phone is sealed, set it up and update immediately. Then test Face ID inside Passwords or Wallet to confirm the fix.

3. Inspect the Camera Rings and Frame in Daylight

Look for pale, pinkish or lighter rings around the three rear lenses. Check the corners of the frame for paint wear. Run a fingernail along the back glass edge to feel for a lip or gap. Do this before you put on a case.

4. Test Both Speakers at Full Volume

Make a call, play a notification, open the keyboard, toggle Airplane Mode, and change brightness quickly. Listen for a tick, pop or crackle from the earpiece and the bottom speaker. If you hear it, do not accept the unit.

5. Check the Display for Lines and Uniformity

Open a white image at full brightness and look for green, pink or red lines, uneven tint, or visible pixel gaps around the Dynamic Island area. Take a screenshot — if the line is not in the screenshot, it is hardware.

6. Skip Matte and Privacy Screen Protectors

Face ID on the iPhone 18 Pro Max sits under the display and is more sensitive to thick films. Use an optically clear protector or none at all. If Face ID fails repeatedly, remove the protector before assuming the phone is faulty.

7. Decide on 256GB vs 1TB Carefully

If you shoot a lot of 4K ProRes video, the 1TB model’s QLC storage may be a bottleneck for sustained writes. For most buyers, 256GB or 512GB is the better balance of price and speed.

8. Budget for AppleCare+ and a Charger

The phone does not include a charger. AppleCare+ is worth considering given the unresolved speaker and cosmetic issues, especially with a ₹42,900 out-of-warranty screen repair cost. If you plan to keep the phone for three years or more, the maths favours coverage.

India return policy reality: Apple’s 14-day no-questions return window is not the same in India as it is in the US. Once you open and activate the phone, returns are handled under warranty and service policies, not a blanket change-of-mind window. Amazon India lists a 10-day service centre replacement window for defective items, so if you buy online, inspect and report immediately. Inspect before you leave the store, and keep the invoice and box in pristine condition.

iPhone 18 Pro Max vs Galaxy S26 Ultra vs OnePlus 15 vs Pixel 11 Pro

The iPhone 18 Pro Max is not competing in a vacuum. Here is how it stacks up against the phones Indian buyers will actually cross-shop.

PhoneIndia PriceKey StrengthKey Weakness
iPhone 18 Pro Max₹1,79,900Best video, A20 Pro, two-day batteryHeavy, unresolved speaker and cosmetic issues
Samsung Galaxy S26 Ultra₹1,39,999S Pen, 5x zoom, 7 years of updates, 214gSmaller 5,000mAh battery, slower charging
OnePlus 15Around ₹81,999Snapdragon 8 Elite Gen 5, 7,300mAh, 120WLower camera resolution, less premium brand
Google Pixel 11 ProFlagship pricingBest AI photo processing, clean AndroidTensor performance lags A20 Pro
Vivo X300 Ultra₹1,59,999 (512GB)200MP + 200MP periscope, 6,600mAhAndroid ecosystem, heavier camera focus
Oppo Find X10 Pro Max₹1,99,999 (512GB)Triple 200MP, 8,000mAh, 80WNewer brand in ultra-premium, software maturity

vs Samsung Galaxy S26 Ultra

The Galaxy S26 Ultra is the obvious alternative. It costs ₹39,901 less, weighs 35g less, includes an S Pen, offers a more versatile 5x optical zoom, and comes with Samsung’s seven-year OS and security update commitment. The iPhone wins on video quality, variable-aperture control and raw battery endurance. If you edit video for a living, the iPhone is worth the premium. If you want the safest five-year Android flagship, the Samsung is the smarter buy.

vs OnePlus 15

The OnePlus 15 is the value champion. At around ₹81,999, it offers Snapdragon 8 Elite Gen 5 performance, a 7,300mAh battery and 120W charging for less than half the iPhone’s price. It will not match the iPhone’s video pipeline or ecosystem, but it is the pragmatic choice for buyers who want flagship speed without the flagship bill.

vs Vivo X300 Ultra and Oppo Find X10 Pro Max

If camera hardware is your priority, the Vivo X300 Ultra at ₹1,59,999 and the Oppo Find X10 Pro Max at ₹1,99,999 offer triple 200MP or 200MP-plus-periscope setups and larger batteries. The iPhone still wins on video and software polish, but the Android ultra-flagships are now genuinely competitive on still photography.

Should You Buy Now, Wait, or Skip the iPhone 18 Pro Max?

Buy Now If:

  • You shoot video professionally or seriously
  • You need the longest iPhone battery life
  • You are already deep in the Apple ecosystem
  • You can inspect the unit in person before paying
  • You are comfortable installing iOS updates immediately

Wait or Skip If:

  • You want zero unresolved hardware complaints
  • You are sensitive to a 249g phone
  • You want the best zoom camera for the money
  • You need seven years of confirmed software support
  • You are buying a US import to save money

The practical move: If you can wait two to three weeks, do it. Apple usually ships a second point update after a rocky launch, and the speaker and build quality reports may get clearer. If you cannot wait, buy from an authorised Indian retailer, inspect the unit before you leave, install iOS 27.0.1 on the spot, and keep every photo and invoice. The phone is excellent — but this is not a launch to buy blind.

Frequently Asked Questions

The five most reported problems are: complete cellular service loss on US AT&T units that requires a hardware replacement, green pink or red vertical line display defects that persist after resets, Face ID freeze and forced reboot loops that Apple partially fixed in iOS 27.0.1, speaker crackle popping and clicking from the earpiece, and build quality defects including back glass that is not flush and pink discoloration around the camera plateau on burgundy and black models.

No confirmed India cases. The SOS and complete service loss reports are tied to a small number of iPhone 18 Pro Max units on AT&T in the United States. The US Pro Max is the only model using a Qualcomm modem, while India units use Apple’s C2 modem. Apple has confirmed that affected US units need a hardware replacement and cannot be fixed by software. Indian buyers should avoid US imports and buy the India model with local warranty.

Yes, mostly. Apple released iOS 27.0.1 on September 28, 2026, which fixes the freeze and restart that occurred when Face ID failed inside a protected app such as Passwords or Wallet. The update also fixes a 2x camera colour artefact and a touchscreen freeze. Some users still report occasional authentication struggles, especially with matte or privacy screen protectors.

Owners describe a clicking, popping or ticking sound from the earpiece and in some cases the bottom speaker. It can be triggered by toggling Airplane Mode, adjusting brightness quickly, receiving notifications, typing, playing music or making calls. iOS 27.0.1 did not fix it, and some replacement units make the same noise. Apple has not publicly commented on whether it is software or hardware.

It is mixed. Several videos and photos show green, pink and red vertical lines on iPhone 18 Pro and Pro Max displays, with reports from India and other markets. Some users received replacements from Apple. However, at least one widely shared image shows a green line running behind the Wi-Fi icon, which is not how a genuine hardware defect behaves. The number of affected units is unknown, and Apple has not confirmed a widespread fault. Persistent lines that do not appear in screenshots are more likely to be hardware-related.

If Apple acknowledges the pale rings around the rear camera lenses as a manufacturing defect, it should be covered under the standard one-year India warranty. Apple has offered replacements to some affected owners abroad but has not publicly confirmed a cause or a repair programme. Indian buyers should inspect the camera rings at unboxing, photograph the unit, and raise a ticket with Apple Support immediately. Out-of-warranty screen repair costs ₹42,900, so warranty coverage matters.

The iPhone 18 Pro Max launched in India at ₹1,79,900 for 256GB, ₹2,04,900 for 512GB, ₹2,54,900 for 1TB and ₹3,29,900 for 2TB. It went on sale on September 18, 2026. Apple is offering ₹7,000 instant cashback on eligible card EMI transactions and ₹6,000 on eligible card full-swipe purchases for both Pro models, according to NDTV.

Most reviews report strong thermals and two-day battery life. The A20 Pro and a vapour chamber three times larger than the previous generation handle sustained gaming well. Some owners reported warmth and faster battery drain during the first few days, usually linked to background indexing, app restore and early iOS 27 software. If heat or drain continues after a week and a software update, run Apple diagnostics.

At 249g and 8.75mm thick, the iPhone 18 Pro Max is Apple’s heaviest iPhone. It is about 35g heavier than the Galaxy S26 Ultra. Most buyers adjust within a week, but anyone with small hands, wrist strain or a preference for one-handed use should hold it in a store before buying.

If you need a phone immediately and want the best iPhone camera, battery and video quality, the iPhone 18 Pro Max is still a strong buy, but inspect it thoroughly at delivery. If you can wait, wait for more iOS 27 updates and for Apple’s position on the speaker and build quality issues. Buyers who want confirmed long-term reliability may prefer the Galaxy S26 Ultra or wait for the next cycle.

The iPhone 18 Pro Max wins on video quality, variable-aperture control, ecosystem integration and raw battery endurance. The Galaxy S26 Ultra costs ₹39,901 less at ₹1,39,999, weighs 35g less, includes an S Pen, offers 5x optical zoom and comes with seven years of OS and security updates. Choose the iPhone for video and Apple ecosystem continuity; choose the Samsung for versatility, zoom and long-term software support.

Check that the box is sealed and the model is the India variant, inspect the camera rings, display and frame immediately for discoloration, lines or paint wear, test the earpiece and bottom speaker at full volume, confirm Face ID works inside a protected app after installing iOS 27.0.1, avoid matte or privacy screen protectors that can interfere with the under-display Face ID module, and buy AppleCare+ if you plan to keep the phone for more than two years.

Final Thoughts: A Great Phone With a Rocky Launch

The iPhone 18 Pro Max is not a bad phone. It is one of the best iPhones Apple has ever made, with a camera system that creators will love, battery life that finally lasts, and performance that makes Android flagships sweat. Beebom’s 8.5/10 rating is fair. Most owners will never see the speaker crackle, the camera rings or the green lines.

But this launch has had more visible problems than any iPhone in recent memory. Apple fixed the scariest software bugs quickly. The ones it has not fixed — the speaker noise, the cosmetic camera-ring issue, and the build quality defects — are exactly the kind of problems that erode trust when you have spent ₹1,79,900 or more. The AT&T cellular failure, even though it is US-only, shows that launch quality control is not perfect.

Our advice is simple. If you want the phone, buy it from an authorised Indian retailer, inspect it before you leave, install iOS 27.0.1 immediately, and keep your invoice safe. If you can wait, wait. The next iOS update may resolve the speaker issue, and Apple may clarify its position on the camera rings. And if you want the safest flagship experience for the next five years, the Galaxy S26 Ultra at ₹1,39,999 is still the more predictable choice.

Either way, do not buy blind. That is the whole point of this guide.
