Step 1

External & Physical Check 🔍

Start with the obvious — the phone’s body. Deep damage often hints at hidden internal problems that will surface months later. Spend a full minute examining every millimeter under good light.

• Body & Scratches: Run your finger along the titanium frame and back glass. Multiple deep dents or a bent chassis suggest the phone was dropped hard. Internal connectors may be loosened.
• Camera Lenses: Look at the three rear lenses. Any scratch, dust inside the lens, or condensation means the camera module is compromised. Image quality will degrade.
• Bottom Screws: The two tiny screws next to the charging port must be pristine. Stripped or loose screws are the #1 sign the device has been opened — possibly for a battery or screen replacement.

Red Flag 🚩 If the phone has a thick case covering damage, remove it. Sellers often hide dents or cracked backs behind a case. Do not accept "it's just cosmetic."

Step 2

Display Check 🖥️

A counterfeit or poorly replaced display is the most common scam on used iPhones. The 15 Pro’s Super Retina XDR display with ProMotion is extremely expensive to replicate — cheap replacements look dull, lack True Tone, and break easily.

• True Tone: Swipe down Control Center, long‑press the brightness slider. If "True Tone" is missing, the display is 100% a fake replacement — original Apple screens always support it.
• ProMotion 120Hz: Go to Settings → Accessibility → Motion. Make sure "Limit Frame Rate" is OFF. Smooth scrolling should be noticeably fluid. Replacements often cap at 60Hz.
• Dead Pixels: Play a pure white and a pure black video on YouTube full‑screen. Any bright or dark spots indicate damaged pixels or a low‑quality panel.

Pro Tip In a dark room, open a black image; the OLED screen should produce absolute black (pixels off). Greyish black suggests an LCD replacement — a major downgrade.

Step 3

Settings & Authenticity ⚙️

The Settings app is your forensic lab. iOS 17 (iPhone 15 Pro) includes a transparent Parts and Service History that reveals if any component has been swapped.

• Parts & Service History: Settings → General → About. Scroll down. "Genuine Apple Part" is good. "Unknown Part" means a third‑party repair. Multiple unknown parts? Walk away.
• Battery Health: Settings → Battery → Battery Health & Charging. Maximum Capacity above 85% is excellent; below 80% means a ₹8,000–₹10,000 replacement is near.
• Cycle Count: (iPhone 15 Pro exclusive) In Settings → General → About, at the bottom. Under 300 cycles is almost new; 500+ indicates heavy usage.
• Model Number: The model number starts with "M" (retail), "N" (Apple replacement), "F" (carrier refurbished). Avoid "P" (personalized) units unless you trust the source.

Quick Model Prefix Guide

M — Retail unit (original purchase) ✅
N — Apple service replacement ✅
F — Refurbished by carrier ⚠️
P — Personalized/engraved ⚠️
3 — Demo unit ❌

Step 4

Hardware & Sensors 🎛️

Sensors like Face ID are cryptographically paired to the logic board. If they fail, a cheap repair is impossible — you’ll face a costly Apple service. Test every hardware feature.

• Face ID: Set up Face ID and unlock the phone multiple times. If it doesn’t work, do not buy — it’s the hardest component to repair.
• All 3 Cameras: Test photos/video at 0.5x, 1x, and 3x zoom. Check autofocus and Cinematic mode. Any blur or failure means a damaged sensor.
• Speakers & Mic: Play a song to check top and bottom speakers. Record a Voice Memo — your voice must sound clear and undistorted.
• Charging: Plug in a wired charger and test wireless/MagSafe. Both must work without interruption. A loose USB‑C port indicates wear.

Hidden Water Damage Pop out the SIM tray and look inside with a flashlight. If the Liquid Contact Indicator (a small white strip) has turned red, the phone has been submerged — voids Apple warranty and may corrode over time.

Step 5

Network & iCloud ☁️

An iCloud locked iPhone is a paperweight. The seller must fully sign out and disable Find My before the phone becomes yours. Then verify cellular connectivity matches your region.

• iCloud & Apple ID: Ask the seller to erase the phone in front of you: Settings → General → Transfer or Reset → Erase All Content and Settings. Set up as new. If they can’t, the phone is stolen or locked.
• SIM / eSIM: Insert a physical SIM (if not a US model) and make a call. USA models have no SIM tray — only eSIM. Ensure band compatibility with your carrier (Sri Lanka uses LTE bands 1,3,5,8,28).
• IMEI Check: Dial *#06# and compare the IMEI with Settings → General → About and the original box. All three must match identically.

Pro Tip

🛠️ 3uTools Verification – Eliminate All Doubt

If you carry a laptop (or the seller agrees), connect the iPhone and run 3uTools — a free PC software that gives a 100% accurate Verification Report. It reads every internal serial number and tells you whether the display, battery, camera, and logic board are original.

In just 3 minutes, you’ll see a green/red verdict for each component. A red mark means it’s been swapped — even if iOS reports “Genuine Part” (some third‑party repairs can spoof that). This is the ultimate scam‑detector.

3uTools Quick Steps

1. Download 3uTools on a Windows laptop (free).
2. Connect iPhone via USB cable; unlock and trust the computer.
3. Click "Verification Report" on the main screen.
4. View colour-coded results:
   - Green ✅ = Original, untouched
   - Red ❌ = Replaced or non-genuine part
5. Take a screenshot for your records.
