Whether you bought your iPhone secondhand, had it repaired, or just want to know what’s really going on under the hood, there’s a hidden screen in your phone that could save you hundreds—maybe even more.

It’s quick to check, easy to miss, and incredibly helpful in spotting fake parts or sketchy repairs.


At The GrayVine, we believe staying one step ahead doesn’t mean you have to be a tech expert.

Just a few smart clicks can help protect your wallet—and your peace of mind!


A scam-stopping screen you already have

Let’s say you snagged a great deal on a “like-new” iPhone.

Or maybe you had a screen or battery replaced at a local repair shop.

Everything seems fine—until a few weeks later when the phone starts glitching, the battery dies fast, or the screen flickers nonstop.

What’s going on? Often, the issue is a non-genuine part—something Apple didn’t make and didn’t approve.

That “affordable” fix can turn into a costly mess.

But Apple quietly added a feature that can alert you to fake parts—and it’s already on your phone.

How to check your iPhone’s Parts & Service screen

Here’s how to find the screen that tells you what’s really inside your iPhone:

1. Go to Settings
2. Tap General
3. Tap About

If your phone is running iOS 15.2 or later, you’ll see a section labeled Parts and Service History.

• If it says Genuine Apple Part next to the battery, display, or camera—you’re good to go.
• If it says Unknown Part, that’s a warning sign. It may be counterfeit, previously used, or simply not working as it should.

If you don’t see a Parts and Service section at all, that just means none of your phone’s parts have been replaced.

Why fake parts are more than just a nuisance

You might wonder—if the phone works, does it really matter?

The answer is yes.

Here’s why Apple and experts recommend using genuine parts:

• Performance problems like overheating, poor battery life, or touchscreen glitches
• Safety risks including swelling batteries or—worst case—fires
• Lower resale value, since used parts make your phone less desirable
• Voided warranty, if repairs weren’t done by Apple or an authorized shop

According to Apple, "Repairs performed by untrained individuals or using non-genuine parts might affect the functionality, safety, security, and privacy of the device."

The Parts & Service screen is just one tool.

Here’s your full checklist for buying secondhand safely:

1. Inspect the device – Check for dents, cracks, or broken ports.
2. Battery Health – Go to Settings > Battery > Battery Health & Charging. If “Maximum Capacity” is under 80%, that battery is worn out.
3. Carrier Lock – In Settings > General > About, find “Network Provider Lock.” If it says No SIM restrictions, the phone is unlocked.
4. Activation Lock – Make sure the previous owner signed out of iCloud. Otherwise, you can’t use the phone.

What to do if something looks off

If your phone shows unknown parts or other red flags:

• If recently purchased, contact the seller right away. Reputable platforms often offer buyer protection.
• If recently repaired, return to the shop and ask questions—especially if they claimed to use genuine parts.
• Still unsure? Visit an Apple Store or authorized service provider for a second opinion.

You don’t have to be a tech wizard to stay safe.

In fact, scammers often target older adults because they assume we won’t know better.

Let’s prove them wrong.

Checking your iPhone’s part history is fast, free, and incredibly useful.

It protects not just your phone, but your investment—and your privacy!
