iPhone Exchange & Replacement Guide: Faults & Next Steps

Quick answer: If your iPhone has a persistent fault, document exactly what happens, try a few safe checks appropriate to the symptom, and request an assessment from the seller or a qualified service provider. An exchange typically means swapping a recent purchase through the seller; a service replacement means receiving another device as part of an approved service outcome. They are not the same process, and a replacement is not automatic because a screen flickers, Face ID fails, or battery life seems short. The seller, purchase details, service diagnosis and available options determine the next step.

You may be looking at a vertical green line on a display that has never been dropped. Perhaps the rear camera makes a clicking sound, Face ID suddenly says it is unavailable, or a recently received replacement iPhone will not activate. These are the situations this guide addresses. It is not another list of Apple Store return deadlines or a claim that every unusual behavior is a manufacturing defect.

For return-window rules on purchases made directly from Apple, consult our Apple return policy guide. For backup, eSIM transfer, preparing a damaged phone, packaging and proof of shipment, use our separate iPhone return preparation guide (link to be added when published). This page owns the defect assessment, exchange/replacement request and replacement-device inspection questions.

iPhone Exchange vs. Replacement: Choose the Right Route

People often use exchange, replacement and repair as if they are identical, but they can describe different outcomes.

What you want	Where to start	What happens next
Swap a recently purchased iPhone that appears faulty	The seller shown on your purchase record	Seller reviews its exchange or return rules and the device’s condition
Have a persistent hardware symptom assessed	Apple Support or an appropriate authorized service provider	Troubleshooting, inspection or diagnostics; repair or replacement may be offered
Receive a replacement under an already approved service case	The provider managing that case	Follow its dispatch, setup and original-device handover instructions
Fix an issue on an iPhone that was itself supplied as a replacement	The service case/provider that supplied the replacement	Report the new symptom, supply the case reference and request a new assessment

An exchange for a different color or storage capacity is a purchasing decision governed by the seller’s policy, not a defective-device diagnosis. Do not treat it as equivalent to replacing an iPhone whose hardware is not working. Likewise, a service replacement is not necessarily a new retail-boxed phone, and it is not automatically an upgrade to the latest model.

Apple’s official U.S. iPhone service page says customers can describe an issue and be guided to possible solutions, repair or replacement. A service provider may inspect the phone before deciding which option is available. If another retailer or carrier supplied the phone, that seller may have a separate process for a purchase exchange.

Before You Request an Exchange: Build a Clear Fault Record

When the defect is intermittent, the most useful thing you can bring to a service appointment is an accurate record, not a long list of guesses from a forum.

Identify the phone. Record its exact model, current iOS version and approximate date you first noticed the issue. The model and software version help avoid irrelevant troubleshooting.
Describe the observable behavior. Write what fails, how frequently, what you were doing and whether the issue happens repeatedly in the same way. For example: “The rear camera shows a black preview in Apple’s Camera app twice a day,” is more useful than “the camera is bad.”
Try a low-risk comparison. Remove a case or accessory if relevant; restart the device if safe; check for an available official software update. Do not erase everything or disassemble a phone just to prove a point.
Capture evidence if possible. Photograph display artifacts with another device; record the result of a camera test; note the exact text of a warning. Avoid sharing your IMEI, serial number or service documents publicly.
Save the outcome of earlier support contacts. Keep diagnostic findings, appointment confirmations and case numbers together so you can explain which checks have already been attempted.

A short description is often enough: “iPhone 17, current software, green vertical line appeared during normal use; persists after restarting; screen protector removed; photo taken with another phone.” That is a useful request for an inspection. It is not proof that the manufacturer owes a particular remedy.

Quick symptom-to-next-step guide

What you notice	Safe first check	What to ask the service provider
Green line, flicker or unresponsive display	Record the symptom; restart if safe	Can the screen be inspected and diagnosed?
Camera preview black or photos persistently blurry	Remove obstructing accessories; test front/rear cameras	Is further camera testing or service recommended?
Face ID no longer sets up	Check settings and TrueDepth area; restart	Can the Face ID/TrueDepth system be evaluated?
Wi-Fi or CarPlay disconnects intermittently	Test another network/cable/vehicle if available	Can the connection issue be reproduced or diagnosed?
iPhone stuck at Apple logo or not turning on	Follow Apple’s non-destructive restart guidance	What are the service options if it still cannot start?
Unusually short battery life on a new phone	Review Battery settings and setup activity	Is the behavior normal setup usage or worth evaluation?
Replacement iPhone fails during activation	Verify Wi-Fi/eSIM setup with carrier if applicable	Who should resolve activation for this replacement?

1. Green Lines, Flickering Displays, and Unresponsive Touchscreens

A green vertical line appeared without a drop. Can I request an exchange?

Yes, you can ask for an assessment. You should not assume that a green line proves physical damage, proves a software bug, or guarantees a complete handset swap. Similar-looking symptoms can have different causes. The practical question is whether the display behaves abnormally during normal use and what the service diagnosis finds.

In a MacRumors thread about a suddenly striped iPhone display, the owner reported horizontal multicolored lines despite routine careful use. In another Reddit discussion about a green line following a beta update, the timing made users suspect software; the discussion illustrates why timing alone is not a reliable diagnosis. Forum replies can suggest things to examine, but they cannot substitute for a technician’s evaluation.

What to record: whether the line is always present or only during startup; whether touch continues to work; whether there were recent updates, drops or moisture exposure; and a clear photo or video captured using a second device. If the phone works well enough, check for an official software update and restart it. Avoid repeatedly pressing, bending or heating the screen to make the symptom disappear.

When contacting support: explain that you want the display assessed. Ask whether the service can repair a display component or whether a replacement device is indicated in your particular case. The available outcome depends on the findings and service program, not solely on the phrase “green line.”

What if the screen flickers only while the iPhone boots?

Distinguish a brief startup animation or display behavior associated with software from a persistent line or flashing during everyday use. Note exactly when the flicker happens and whether it continues after startup. A video is useful when the symptom lasts only seconds. A technician might ask for an update or other diagnosis before proposing hardware service.

Can I exchange a phone with a cracked display?

A cracked screen is not the same situation as a line appearing without visible damage. Your options may differ because the condition and cause matter to the seller or service provider. This article does not assess accidental-damage coverage or promise a free exchange. If the glass is unsafe to touch, stop using it and ask a professional how to present it for inspection. For physically preparing an already-authorized shipment, consult our return preparation guide instead of attempting home repairs.

2. Camera Faults: Black Preview, Focus Failures and Unusual Noise

The Camera app shows black or refuses to focus

Apple’s camera troubleshooting guidance recommends ruling out cases, films and magnetic accessories, cleaning the lens, restarting and updating the device, and trying both front and rear cameras. Follow those simple checks before requesting a device exchange. If the Camera app still opens to a blank image or consistently fails while using the normal camera, describe exactly what happens and request service.

A useful test record is: “The rear wide camera is black, but the front camera works; this happens in Apple’s Camera app, without an accessory attached.” This is a much more useful diagnostic starting point than blaming the device model or a specific iOS update without evidence.

My iPhone camera rattles when I put it on a table. Is it defective?

Not necessarily. A sound near the camera assembly by itself does not establish a fault. Some camera designs include moving stabilization and focus components. Rather than shaking the phone repeatedly, check whether it also shows a meaningful malfunction: persistent inability to focus, unstable images during ordinary use, a camera that cannot initialize, or a recurring error.

Owners have asked about a rattling camera on the iPhone 17 Pro and whether camera noise accompanies intermittent camera failure. These discussions highlight why the symptom that affects use matters more than a sound heard when a phone is deliberately shaken. If image quality or operation fails, record an example and seek assessment.

Camera quality looks worse than an older iPhone

First compare like with like. Check whether the same lens, photo mode, lighting and zoom are in use. Remove any lens protector or case that covers the camera. If the problem persists in ordinary conditions, capture repeatable examples rather than assuming every processing difference is a broken sensor. A forum discussion about iPhone 17 photo quality shows how difficult it can be to distinguish preferences about image processing from an actual repeatable defect.

3. Face ID and TrueDepth Camera Failures

A Face ID error can feel like a handset-wide failure because it affects unlocking and apps. But an exchange decision should begin with basic checks, not assumptions about a damaged sensor.

Apple’s Face ID support article recommends checking the settings, making sure the TrueDepth area is unobstructed, updating the device, restarting and—when appropriate—resetting Face ID. If Face ID cannot be set up or repeatedly fails, professional service may be required.

In one Reddit post about Face ID being disabled unexpectedly, the owner reported no obvious drop. In a separate 2026 discussion, Face ID temporarily failed in a way that also affected the owner’s ability to access apps, then later worked again. The takeaway is to record whether the failure is continuous or intermittent, rather than assume a permanent hardware defect from one episode.

Do not attempt to open or modify the TrueDepth system yourself. If Stolen Device Protection or account security prevents a settings change, describe that limitation to official support; avoid following forum instructions that bypass security controls.

What to ask: “Can you inspect the TrueDepth/Face ID issue and advise whether the outcome would be a repair or a device replacement?” That keeps the request focused on a verified service path.

4. Wi-Fi, Bluetooth, Cellular and CarPlay: When Is an Exchange Reasonable?

Connectivity symptoms deserve special care because a failure may be related to a router, car stereo, cable, carrier setup, software version or the phone itself. A single failed connection is not evidence of defective hardware.

For intermittent Wi-Fi, check whether the problem happens on more than one network and whether other devices stay connected. For Bluetooth, test another compatible accessory. For wired CarPlay, Apple’s CarPlay troubleshooting page recommends checking cable and port combinations; for wireless CarPlay, check the relevant Wi-Fi and Bluetooth settings and vehicle compatibility.

A MacRumors discussion of intermittent Wi-Fi behavior on some iPhone 17-family devices illustrates why users sometimes seek an exchange after repeated connection drops. However, a forum pattern is not proof that every device of that model is affected or that an exchange is the best fix.

Useful evidence to share: the iPhone model and software version, whether the issue also occurs with a second known-working network or accessory, a short description of when it fails, and which official troubleshooting steps did not help. If your cellular plan will not activate, contact the carrier as well: replacement hardware and service provisioning are different parts of the setup.

5. iPhone Won’t Turn On, Reboots Repeatedly or Gets Stuck on the Apple Logo

If an iPhone is unresponsive, Apple provides a model-specific force-restart procedure. On Face ID models, that generally involves quickly pressing Volume Up and Volume Down, then holding the Side button until the Apple logo appears. If it will not power on, Apple advises charging and trying again as directed. Use the instructions that apply to your model.

For a phone stuck on the Apple logo during migration or restoration, Apple describes a recovery-mode process. It distinguishes Update, which attempts to update the device, from Restore, which erases it. Do not choose a destructive option simply to strengthen a replacement request; consider data recovery and backup implications first.

A MacRumors discussion about an iPhone 17 boot loop and restore error shows the kind of situation where owners may reasonably seek professional diagnosis after standard steps fail. Record the error text and troubleshooting history, and ask the service provider whether it can be repaired or whether a replacement is a viable service outcome.

If the phone is unusually hot, physically damaged, smells abnormal, or appears to have a swollen battery, stop troubleshooting and request professional safety guidance rather than continuing to charge or press it. Those cases are not the subject of this exchange guide.

6. New iPhone Battery Drains Fast: Exchange or Normal Setup Activity?

Battery drain on a recently set-up device is frustrating, but it is not automatically a defective battery. Apple notes that ongoing device setup and an iOS update can temporarily increase background activity. Its battery-life guidance recommends examining Battery settings, app activity and insights before concluding that a component has failed.

Start with the actual pattern: What percentage is lost during comparable idle periods? Is screen use or a particular app accounting for the drain? Did it begin right after restoring data or installing a software update? Is the phone in a low-coverage area or being used with a demanding app?

If you can reproduce highly unusual behavior after setup activity has settled, record Battery settings and describe the pattern to the seller or provider. Request an inspection rather than assuming a free replacement will be approved. A percentage from one day, without the workload and conditions, is rarely enough to establish a battery fault.

This section addresses a suspected defect in a new or replacement phone, not long-term battery wear, battery-replacement thresholds or extended warranty disputes.

7. How to Ask for an iPhone Exchange or Service Replacement

Use the following workflow after you have identified a persistent issue. The goal is to make the next conversation productive, not to demand a particular outcome before anyone examines the device.

Decide who should handle the request. For a newly purchased phone, begin with the retailer who sold it if you are seeking a purchase exchange. For an ongoing service case or a replacement provided by Apple, contact the support team managing that case. If unsure, use Apple’s iPhone service page to explore options.
Explain the exact fault. Give the model, symptom, frequency, steps that reliably trigger it, and when it began. Mention safe checks you have already completed.
Ask for the available service pathways. A representative may suggest troubleshooting, inspection, a component repair or a replacement. If you are specifically asking for a replacement, ask what findings or next steps are needed for that option to be considered.
Record the case details. Save your reference number, appointment, shipping or service instructions, and any written description of the diagnosed issue.
Do not erase or ship prematurely. Once the provider confirms the process, follow its instructions. The preparations for an approved exchange, an ordinary purchase return and an in-progress repair can differ.
Follow up with the same case reference. If you have already completed diagnostics, ask the next representative to review the existing service record so you are not starting again from the beginning.

Apple offers in-person and mail-in service. Its website explains that service options and final assessments can vary by device, diagnosis, parts availability and location. Keep your request factual and focused on restoring a properly working phone.

Exchange request example

“My iPhone [model] has a repeatable [screen/camera/Face ID] fault. It occurs [when/how often], and I have tested [safe checks] without resolving it. I have the purchase or service reference and a short video of the behavior. Could you advise whether the device should be inspected and whether repair or replacement is available?”

This type of clear description is more useful than claiming every device in a forum thread has the same defect.

8. Is an Apple Service Replacement iPhone New or Refurbished?

Do not assume that a service replacement means a factory-sealed retail phone. Apple’s U.S. iPhone service information states that equipment supplied as part of service can contain new or previously used genuine Apple parts that have been tested to meet Apple’s functional requirements. That is the reliable source to cite—not a rumor about the first character of a model number or the color of a shipping box.

This question is frequently raised in forums, including a 2025 discussion about whether replacement iPhones are new and a 2026 discussion about model numbers on replacement phones. Such threads reveal what buyers are concerned about; they do not establish a universal factory-origin rule for every replacement.

What matters in practice: the correct model and storage size, clean setup and activation, usable cameras and sensors, normal display behavior, connectivity and the service details shown in your records. A replacement supplied through service is not necessarily the same as purchasing an Apple Certified Refurbished phone from the retail store.

Apple says its service and replacement parts are guaranteed for 90 days or the remaining term of the existing Apple warranty, whichever is longer, subject to the applicable service terms and any other coverage. Check the paperwork specific to your case instead of assuming the replacement automatically restarts a new one-year retail warranty.

9. How to Check a Replacement iPhone When It Arrives

Run these checks soon after receiving a replacement, while your service case details are easy to access. This list is about evaluating the device delivered to you, not repeating the packaging and shipment steps from the return guide.

Check	What to look for
Model and capacity	Confirm the correct iPhone family and storage in Settings > General > About when accessible
Exterior and display	Look for visible marks, lines, unusual color patches or unresponsive touch areas
Cameras and flash	Test front and rear lenses in normal light; confirm focus and recording
Face ID and buttons	Test Face ID setup if supported, volume and side controls
Wi-Fi and Bluetooth	Connect to a known-working network and familiar accessory
Cellular activation	Verify eSIM or physical SIM works as appropriate to your model and carrier
Speaker and microphone	Test a short recording and playback without sharing private material
Charging and battery	Confirm normal charging behavior and inspect Battery settings
Service record	Keep the dispatch confirmation, service reference and any replacement documentation

Do not treat a newly restored device’s initial battery activity as evidence of a defect without checking for setup activity. Similarly, a single failed CarPlay attempt should be compared with another cable, port or vehicle when possible.

The replacement phone itself has a fault

Report the issue against the replacement service case, rather than submitting an unrelated purchase return and starting from zero. Provide the original service reference, the replacement’s identifying details privately, the date it arrived, and the newly observed symptom. Ask the provider to advise the correct next service step.

An older MacRumors report about a replacement iPhone developing a green line is an example of the issue—not evidence that it is common to all replacement devices. The appropriate response is a prompt assessment with the provider that supplied the handset.

Wrong model, color or storage capacity

Compare the replacement and your service or fulfillment documentation. Record the discrepancy immediately and ask the issuing provider to verify which device was authorized. A purchase-color exchange and an incorrectly fulfilled service replacement are different situations. Do not activate and transfer everything to a clearly incorrect unit before checking whether the provider wants it returned.

10. Replacement iPhone Won’t Activate or Has No Cellular Service

A replacement may start normally yet fail to register an eSIM or connect to a cellular network. Do not jump from an activation error to the conclusion that the whole phone is defective. The issue may lie in carrier provisioning, an incomplete eSIM transfer, activation settings or the device itself.

Apple’s cellular setup instructions describe carrier activation, eSIM Quick Transfer, QR codes and carrier apps, with availability depending on model and provider. Check Wi-Fi and the carrier instructions before attempting repeated resets. If service activation remains blocked, contact your carrier with the activation error and ask whether the line is provisioned for the replacement device; also notify the device provider if basic device functions or settings are unavailable.

Owners have described replacement and new-device activation difficulties, including an iPhone eSIM activation thread and an earlier number-transfer discussion. These are examples of questions to ask, not universal technical diagnoses. Avoid posting full IMEI or EID identifiers online or randomly deleting the only functioning eSIM.

If the phone boots to Activation Lock linked to an account you do not control, contact the official device provider and supply its service case rather than attempting to bypass the lock or sharing someone else’s credentials.

11. Replacement Delivery Status, Handover and the Original Device

If a replacement has been approved but has not arrived, verify the tracking or service status using the official case information rather than interpreting an unverified forum delivery estimate as a promise. Apple’s My Support repair tracking provides a way to review current or recent cases. Ask the issuing provider whether the unit has dispatched and whether it needs any additional information.

For approved Express Replacement Service, Apple explains that the replacement may be sent before the original device is returned and provides instructions for the original-device handover. The program is not available for every service case or region. Follow the directions and deadlines supplied with your actual case; do not assume all providers have the same service process. See Apple’s Express Replacement overview.

Once your next device is ready, the separate return-preparation guide explains backup, account settings, transferring eSIM, packing, and proof of handoff. Do not erase an original device before completing any necessary data transfer and receiving the correct instructions. Apple also offers a Ready for Repair or Trade In feature on eligible devices and service workflows, so it is particularly important not to apply a blanket Find My instruction to every repair.

This article intentionally does not cover credit-card holds, insurance disputes, stolen-device claims, chargebacks or compensation strategies. Those are separate issues from diagnosing a defective handset and completing an exchange or service replacement.

12. Real Customer Situations: What to Do Next

The following are paraphrased scenarios based on recurring types of forum questions, not quotations or promises about any reader’s eligibility.

“My new iPhone suddenly has a green line, but I have not dropped it.” Record a second-device photo and when it appears. Restart and check relevant software steps if safe. Request a display diagnosis; let the inspection determine whether repair or replacement is available.

“The iPhone camera clicks when I put it down.” Test ordinary shooting and video performance. Sound alone is not proof of a defect. If the camera cannot focus or reliably initialize, document the effect on use and request assessment.

“Face ID says unavailable even though the phone looks fine.” Check Apple’s supported settings and unobstructed TrueDepth area. If setup repeatedly fails, report the warning exactly and request service; do not open the front sensor assembly.

“CarPlay keeps dropping, so I want a different phone.” Try the car manufacturer/Apple’s recommended checks, another cable or available network, and note which combinations fail. A failed connection in one car does not by itself show a handset fault.

“My new iPhone’s battery loses charge overnight.” Review Battery usage, recent setup/update activity and app activity. If behavior remains markedly abnormal and repeatable, present the evidence for evaluation.

“Apple sent a replacement, but it has a screen defect.” Contact the service case owner promptly with the replacement reference and evidence. Do not file an unrelated return without confirming the correct process.

“The replacement turns on, but my eSIM will not activate.” Check supported carrier activation steps, Wi-Fi and the line’s provisioning. Keep both the carrier and service case reference so the two parties can identify where the setup is failing.

Frequently Asked Questions

Can I exchange an iPhone because the camera makes a noise?

You can request an inspection, but noise alone does not establish a faulty camera or entitlement to an exchange. Describe actual problems with focus, image quality or camera operation if those occur.

Does a green line mean Apple must replace the whole iPhone?

No. It is a reason to investigate a display fault, not a guarantee of a complete handset replacement. Inspection and available service options determine the outcome.

Can I get an iPhone replacement after an iOS update causes a boot loop?

If safe official startup and recovery guidance does not solve the issue, ask for a diagnosis. A software update occurring shortly before a fault does not prove the cause or establish a specific service outcome.

Can an iPhone with nonworking Face ID be exchanged?

A persistent Face ID failure can justify asking for assessment. Check the supported software and TrueDepth troubleshooting steps first. The provider decides which service options are available after evaluation.

Is a service replacement guaranteed to be brand-new?

No. Apple says service equipment can contain new or previously used genuine parts that have been tested. Review the actual case documentation rather than relying on model-number rumors.

Does a replacement restart a full new one-year warranty?

Not automatically. Apple’s U.S. service page describes its service guarantee as 90 days or the remainder of the existing warranty, whichever is longer, with other coverage terms potentially applying.

What if my replacement iPhone has a fault when I first turn it on?

Document the symptom and contact the provider that supplied the replacement under the original case. Explain that the defect concerns the replacement handset, not a new retail purchase.

Do I need to erase my old iPhone before the replacement arrives?

Not as a blanket rule. Complete necessary backup and transfer and follow the instructions for your approved service. Some repair workflows now support keeping Find My enabled. For the handover checklist, use the separate iPhone return preparation guide.

What if the replacement iPhone cannot activate an eSIM?

Follow Apple’s eSIM setup guidance and confirm the carrier has provisioned the line correctly. If the device itself fails to expose normal cellular controls or setup remains blocked, report those details to Apple or the device provider.

Should I send the charger and original box when returning the old phone after replacement?

Follow the packing instructions supplied with that service case. Do not send accessories that have not been requested. Our separate iPhone return preparation guide covers the broader packing and shipment checklist.

Is exchanging a phone for another color the same as service replacement?

No. A color or storage exchange is a purchase-policy question for the original retailer. Service replacement follows a diagnosis or approved service process. For Apple’s retail-purchase rules, see the Apple return policy guide.

Final Checklist: Before You Accept or Return a Replacement

I have identified whether this is a retail exchange, an assessment or an approved service replacement.
I have a clear description and evidence of the defect.
I know the correct seller or service provider for the request.
I have recorded my case reference and the provider’s next steps.
I have checked the replacement’s model, storage and physical condition.
I have tested screen, camera, Face ID where supported, Wi-Fi and cellular activation.
I have reported any newly detected fault against the original service case.
I have confirmed the correct preparation instructions before handing over the old iPhone.

Bottom line: A useful iPhone exchange or replacement request begins with an observable symptom and ends with a documented service outcome. Describe the fault, run safe checks, seek an assessment when needed, and inspect the replacement promptly. Keep retail policy questions, original-device shipping preparation and financial claims in their own dedicated resources rather than assuming every question has the same answer.
