How to spot fake electronics in Nairobi — a 7-point checklist

Counterfeit phones, TVs and laptops slip into the secondhand market every week. Here's the field-tested checklist Corido inspectors use before approving a Verified listing.

Buying secondhand electronics in Nairobi can save you serious money — a MacBook that retails for KES 180,000 brand new can be found in excellent condition for KES 90,000 or less. But the same market that creates those savings also attracts fakes. As a Senior Inspector at Corido, I spend my days reviewing listings and physically inspecting high-value items before they earn a Verified badge. This is the exact checklist we use.

1. Check the IMEI against the manufacturer's database
For any phone, dial *#06# and the IMEI appears. Cross-check it at imei.info. A genuine device returns the correct model, origin country and network lock status. A mismatch — or worse, a result that says "not found" — is a hard stop.

2. Look at the charging port under a torch
Genuine Apple Lightning and USB-C ports are machined with tight tolerances. Clone ports often have visible gaps, off-centre pins or a greenish corrosion tint even on "new" devices. Micro-USB ports on Samsung and Tecno clones frequently show loose contact with the cable — if the cable falls out with a gentle tug, walk away.

3. Run the device for 10 minutes under load
Clones use underpowered chipsets that throttle immediately under load. Open a video in 1080p on YouTube, start a download, and open a navigation app simultaneously. A genuine mid-range device handles this without the screen dimming or the chassis becoming too hot to hold. Clones often get uncomfortably warm within three minutes.

4. Verify the serial number in the manufacturer's service portal
Apple: checkcoverage.apple.com. Samsung: samsung.com/global/galaxy/warrantyinformationpage. A genuine device shows warranty status and purchase region. A cloned device either returns an error or shows a completely different product.

5. Inspect the software build number
On Android, go to Settings → About Phone → Build Number. A genuine Samsung, for instance, will show a build string starting with the correct model code (e.g. SM-A546 for the A54). Clone firmware often shows a generic build string like "alps" or "mtk" — a clear sign the device is running MediaTek clone firmware masquerading as a brand device.

6. Test the cameras with a demanding scene
Point the camera at a newspaper in mixed indoor lighting and zoom to 2×. Genuine cameras render readable text and maintain exposure without banding. Clone cameras — even those claiming 64 MP — smear fine detail and introduce purple fringing that no genuine sensor in this price bracket would produce.

7. Ask for the original box and purchase receipt
Genuine retail boxes have a consistent font weight on the print, a QR code that scans to the manufacturer's website, and a KEBS import sticker if the device was purchased in Kenya through official channels. A seller who cannot produce the box for a device they claim to have bought six months ago should be asked why not. A Corido Verified badge means our inspector has already run this checklist — but for unverified listings, you are your own first line of defence.

If you buy through Corido Secure Pay and a device fails authentication after delivery, our dispute team reviews the case within 24 hours and the escrow is held until resolution. That protection does not exist if you pay cash on delivery outside the platform.
