Buying a smartphone—whether new, used, or refurbished—is a big investment. Unfortunately, duplicate, clone and fake phones are still common in offline markets and online listings. These devices often look genuine at first glance but use low-quality hardware, modified software, or fake branding. Over time, they cause poor performance, security risks, and money loss.
This detailed guide explains how to check if a phone is original or duplicate, step by step, for both Android phones and iPhones. You don’t need technical knowledge. Just follow these practical checks before paying.
Why It’s Important to Check Phone Originality
A duplicate or fake phone may cost less upfront, but it usually brings long-term problems:
- Slow performance, poor specs and frequent crashes

- No valid warranty or service support
- Poor resale value

Understanding Duplicate, Clone and Fake Smartphones
A duplicate phone is a device that:
- Copies the design and name of a popular smartphone
- Uses cheap processors, cameras, and batteries
- Runs modified or fake Android software
- Shows false specifications in settings
These phones are commonly sold as:
- “Imported models”
- “Refurbished at very low price”
- “Same as original but cheaper”
Original smartphones are made following many authentic step-by-step processes and then reach stores.
Most Reliable Ways to Check If a Phone Is Original
1. Check the IMEI Number (Most Important Step)
The IMEI (International Mobile Equipment Identity) is a unique number given to every genuine mobile device.
How to check IMEI Number:

- Dial *#06# on the phone
- Note the IMEI number shown
- Match it with:
- IMEI on the phone box
- IMEI printed on SIM tray or back panel
- IMEI shown in Settings → About Phone
👉 All IMEI numbers must match.
If they don’t match, the phone is likely duplicate, repaired, or tampered.
You can also verify the IMEI on the manufacturer’s official website to confirm the brand and model.
How to Check a Stolen Phone Using IMEI
You can check whether a mobile phone is stolen or genuine by using the Sanchar Saathi CEIR IMEI Verification portal provided by the Government of India. Simply visit the official IMEI verification page, enter the phone’s 15-digit IMEI number and your mobile number, and submit the details. The system will show the current status of the device, such as whether it is active, blocked, or reported lost or stolen. This easy online check helps you stay safe while buying a new or second-hand phone and protects you from using illegal or blacklisted devices.

Check carefully:
- Brand name

Red flags:
- Misspelled brand or model
- Unknown model numbers
- Android version that doesn’t match the phone’s release year

How to Check If an Android Phone Is Original

3. Use Android Hardware Test Codes
Most original Android phones support built-in test codes.
Try dialing:
- *#0*# → Hardware test menu (many brands)
- *#*#4636#*#* → Phone and network information
If these codes don’t work or show very limited info, it may indicate modified software.
4. Check Hardware Using Trusted Apps
Install a reliable hardware-info app from the Play Store.
Check:
- Processor brand and model

- Camera sensors
- Battery information
Duplicate phones often display fake processor names that don’t match actual performance.

Original Android phones:

Fake or duplicate phones may:
- Lag heavily even in basic apps

How to Check If an iPhone Is Original

iPhones are harder to fake, but duplicates do exist—usually running modified Android software.
6. Check Serial Number and Model Number
Go to Settings → General → About and note:
- Serial Number
- Model Number
Verify these details on Apple’s official coverage page.
If the serial number is invalid or shows a different model, the phone is not original.
7. Check the App Store
Original iPhones only have the Apple App Store.
If you see:
- Google Play Store
- Dual app stores
- Android-style settings
👉 The phone is 100% fake.

Original iPhones support:
- iCloud
