Buying a phone in India, whether new, second-hand or refurbished, comes with one big worry: is this handset genuine or a clever clone? Fake phones look convincing today, with copied logos, similar boxes and lookalike software. The good news is that you need no technical knowledge to catch them. This guide covers the IMEI check, quick display and camera tests, accessory red flags, and a practical 10-point checklist to run before you pay a single rupee.

Start With the IMEI Check — It Takes 30 Seconds

The IMEI (International Mobile Equipment Identity) is a unique 15-digit number assigned to every genuine phone, and the fastest way to confirm a device is original.

• Dial *#06# on the phone. The IMEI number (two numbers on dual-SIM phones) appears instantly on the screen.
• Match it everywhere. The number on the screen must match the IMEI printed on the retail box and, on many models, on the SIM tray or back panel.
• Check the settings too. Go to Settings, then About Phone, and confirm the same IMEI appears there as well.

Verify the IMEI officially

In India, you can check an IMEI on the government’s Sanchar Saathi (CEIR) portal, which confirms the number is valid and not reported lost or stolen. Brands like Apple and Samsung also let you enter the serial or IMEI number on their websites to confirm the exact model, colour and warranty status. If the site shows a different model from the phone in your hand, walk away — that is a classic clone sign.

Display, Touch and Camera Tests

Clone makers cut corners on the screen and cameras, the most expensive parts of a phone.

• Brightness and colours: Original displays look sharp and bright even outdoors; clone screens look washed out or blurry when you read small text.
• Touch response: Type a message and drag an icon — genuine phones respond instantly, while fakes lag, miss taps or scroll jerkily.
• Camera quality: Check that every listed lens actually works; clones often add fake lenses that are just plastic circles. Take a photo and zoom in — original cameras keep detail, fakes turn grainy quickly.
• Video test: Record and play back a short clip; fakes often stutter or fail at their listed resolutions.

Build Quality and Accessory Red Flags

Hold the phone and trust your hands. Original devices have even gaps, firm buttons and a solid feel. Warning signs include:

• Misspelled brand names or blurry logo printing on the phone or box.
• Loose buttons, rough edges or a back panel that flexes when pressed.
• A charger or cable that feels flimsy, has faded printing or lacks proper markings — fake accessories usually come with fake phones.
• Weight that feels noticeably lighter than the official specification.
• Missing or poorly printed warranty card, manual and box seals.

Software Checks That Expose Clone Phones

Software is where most clones fail badly, because copying hardware is easier than copying an operating system.

1. About Phone details: In Settings, check the model number, OS version, RAM and storage. If the box says 8GB RAM but the phone shows 3GB, it is fake.
2. Official app stores: A genuine Android phone runs the real Google Play Store; a genuine iPhone runs the App Store with iCloud sign-in. Clones ship with lookalike stores that crash or demand odd permissions.
3. System updates: Original phones connect to the brand’s update server; clones usually show errors when you check for updates.
4. Pre-installed junk: A flood of unknown apps you cannot uninstall is a strong clone warning.

The Practical 10-Point Original Phone Test

Run through this list before you accept any phone:

1. Dial *#06# and note the IMEI number.
2. Match the IMEI with the box, SIM tray and Settings.
3. Verify the IMEI on the Sanchar Saathi portal or the brand’s website.
4. Inspect the logo, printing and box seals for spelling or quality errors.
5. Check display sharpness, brightness and touch response.
6. Test every camera lens, plus one photo and one video.
7. Confirm RAM, storage and OS version match the official specification.
8. Open the Play Store or App Store and download one app.
9. Insert your SIM and make a test call.
10. Examine the charger, cable and accessories for genuine markings.

This checklist works for refurbished phones too. Trusted sellers welcome such checks — at Campus Mobile’s refurbished phone store, every device is tested and IMEI-verified before dispatch, and Cash on Delivery means you pay only when the phone reaches you.

Frequently Asked Questions

What if *#06# shows no IMEI number?

If the code shows nothing, an error, or a number that fails verification, do not buy. Every genuine handset sold in India has a valid IMEI.

Can a clone phone have a valid IMEI?

Some clones copy IMEI numbers from real phones, so also match the model details on the brand’s website and run the software checks — a copied IMEI cannot fake the operating system.

Are refurbished phones original?

Yes — a properly refurbished phone is an original device that has been tested, repaired where needed and resold at a lower price, often 30-50% cheaper than new. Buy from a seller who shares the IMEI and offers a warranty or replacement policy.
