How to Check if an Android Phone Is Fake, Clone or Original

The “Galaxy S25 Ultra” is half the usual price, the box looks right, and the home screen looks just like One UI. Then a free hardware app reports a low-end Unisoc chip and a fraction of the storage on the label. To check if a phone is original before you pay, you need the few checks a clone can’t easily fake, and they take about ten minutes.

They work on Samsung, Google Pixel, Xiaomi, Motorola and other Android brands. For iPhones, see our separate article on spotting fake and refurbished iPhones.

Clone, re-housed or refurbished?

A clone (or replica) comes from an unknown factory and is built to look like a famous model. It runs a modified Android build with a skin that copies the real one, plus fake “About phone” information. A re-housed or re-labelled phone is genuine but older or cheaper, put into a new shell or given false labels and a box. A refurbished phone sold as new is a genuine device that’s been repaired, sometimes with non-original parts.

Clones turn up most in markets with a lot of informal phone trading, including parts of Africa, the Middle East and Asia, and on online marketplaces everywhere. The checks below catch all three.

The IMEI should match in three places

The IMEI is the phone’s hardware identity, and on a genuine phone it’s the same everywhere you look.

1. Dial *#06# in the phone app. The IMEI (two on dual-SIM phones) should appear straight away.
2. Compare it with Settings › About phone (on Samsung, also Settings › About phone › Status information).
3. Compare it with the box label and, if it’s printed there, the SIM tray or the back of the phone.

Any mismatch is a serious red flag. Then check the number itself is valid. The last digit of every IMEI is a check digit calculated with the Luhn formula, so an invented number usually fails. Our article on the IMEI check digit shows how to test it by hand.

The first eight digits are the TAC (Type Allocation Code), which identifies the manufacturer and model; what a TAC code is explains it in more detail. Clone makers often reuse an IMEI from a cheap phone or make one up. Run a manufacturer and model check. If it comes back as a different brand, or a low-end model instead of the flagship in your hand, the phone isn’t what it claims to be.

Decoding a Samsung model number

Every Samsung phone has a model code starting with SM-, in Settings › About phone and on the box. It identifies the exact model and region. The Galaxy S25 Ultra, for example, is SM-S938, with a suffix letter such as B (international), U (US carriers) or N (Korea). Our Samsung model number and CSC explainer goes through every part.

Be suspicious of a code that doesn’t start with SM-, doesn’t match the model name, differs between the box and settings, or belongs to a different, cheaper model. A Samsung Info report on the IMEI shows the model, region, warranty and more.

Pixel, Xiaomi and the rest

On a Google Pixel, check the model in Settings › About phone and confirm it with a Google Pixel Info check. On Xiaomi, Redmi and POCO, look at the model and HyperOS version in Settings › About phone, and run a Xiaomi check for region and lock details. For Motorola, OnePlus and others, compare the model in settings with the box and the manufacturer’s spec page.

What a hardware app sees that “About phone” hides

A clone can fake the About phone screen. It can’t easily fake what a hardware info app reads from the chip. Install a reputable one from the Play Store, such as CPU-Z, AIDA64 or Device Info HW, and compare:

Clones often show a fake Android version and storage figure. One quick test: copy a big video or a large folder of files onto the phone. Fake storage often fails or corrupts files well before the claimed capacity.

Play Protect and the brand’s own apps

Genuine Android phones from major brands are certified by Google. In the Play Store, tap your profile picture › Settings › About and look at Play Protect certification. It should say Device is certified. Many clones are uncertified, and some have no real Play Store at all. Our Play Protect certified check article covers what to do if yours says otherwise.

Then try the things only the real brand’s software can do:

• On a genuine Galaxy, Samsung Members › Support › Phone diagnostics runs hardware tests. On clones the app is often missing, crashes, or can’t run them.
• Signing in to a Samsung account and updating from the Galaxy Store should just work.
• Settings › Software update (Samsung) or Settings › System › Software updates (Pixel) should contact the manufacturer’s servers. Clones often show a fake “up to date” screen or a third-party updater.
• Zoom levels, 8K or 4K video and night modes should match the spec. Clones usually have low-resolution sensors that can’t deliver the claimed zoom.

Signs you can see and feel

• A price far below the market for that model and condition.
• Logos, fonts or spacing on the box that look slightly off, or regulatory text that’s missing or misspelled.
• Uneven gaps, low weight, loose buttons, or a plastic frame on a phone that should be metal.
• Camera lenses that are partly fake: painted, or dummy rings.
• A pre-installed “Play Store”, or apps that don’t look like the real ones.
• On a supposed Galaxy Ultra, no S Pen in the silo, or a stylus that doesn’t bring up the Samsung S Pen menu when you pull it out.

A genuine phone can still be blacklisted, financed or locked to a carrier, so check the IMEI for those too. Your first All-in-one Basic Info check is free:

The surest way to avoid clones is to buy from the manufacturer, an authorised retailer or a carrier. Buying used, insist on doing these checks in person.

If you’ve already paid for a fake

1. Don’t use it for anything sensitive. Uncertified clones often run outdated software without recent security patches, so keep banking and email apps off it.
2. Save the evidence: the listing, the chat messages, the payment receipt, and screenshots of *#06#, the About phone screen and the hardware app results.
3. Contact the seller and the platform. Most marketplaces and payment providers have buyer protection for items “not as described”, but the claim windows are short.
4. Dispute the payment if you paid by card or through a payment app that allows it. Cash usually can’t be disputed.
5. Report it to the platform and to your local consumer protection authority.
