Choosing a Xiaomi smartphone, many are faced with a dilemma: buy an official device with a warranty from a Russian dealer or save on a gray device ordered from China or brought to order? The difference in price between them can reach 30-50%, but with the savings, the buyer gets a whole bunch of potential problems - from the lack of warranty service to the sudden locking of the device.
In this article, we’ll look at 7 critical differences between gray and official Xiaomi smartphones that directly affect the user experience, from firmware and updates to NFC and Google Pay. You’ll learn how to verify the origin of the phone before you buy, which models are most often blocked, and why even the “global version” from AliExpress can turn into a “brick” after a year of use.
1.What is Xiaomi’s “gray” and where does it come from?
A grey phone is a device that was intended to be sold in one region (e.g. China or India) but through parallel imports has been shipped to another country without an official dealer.
- 📦 Chinese versions (with firmware) MIUI China) ordered on AliExpress, Taobao or through intermediaries.
- 🌍 "Global" versions for Asia (MIUI Global, but not certified for the EU/Russia (e.g. Redmi Note 12 Pro)+ 5G Indonesian).
- 🔄 Used or refurbished devices resold as new (often with "clean" firmware).
Official smartphones come to Russia through authorized distributors (Xiaomi Russia, M. Video, Svyaznoy), have Russian-language firmware MIUI RU and full support for service centers, the main difference is that they undergo local certification (including compatibility checks with Russian 4G/5G networks and security standards).
💡
If the seller claims that the phone is “official, but without a box” or “brought from a business trip”, ask for a warranty document stamped with the stamp of the Russian service center.
2.Guarantee: Why Xiaomi's grey can't be fixed even for money
The most obvious difference is warranty service: official Xiaomi smartphones in Russia have a warranty of 12 to 24 months (depending on the model), which can be implemented in any authorized service center.
| Criteria | Official Xiaomi | Xiaomi's grey |
|---|---|---|
| Guarantee period | 12-24 months | Absent or 7-14 days from the seller |
| Service centres | Any authorized (free) | Only paid repairs in informal workshops |
| Spare parts. | Original, with guarantee | Analogues or b/w, no guarantee |
| Repair time | 3-10 days | 2 weeks (depending on the availability of details) |
The key problem with gray phones is the lack of official parts. For example, if the Xiaomi 13 Ultra has a broken screen, the service center for the official device will install the original matrix from Samsung Display, while maintaining leakage. In an informal workshop, you will likely be offered a Chinese counterpart with the risk of detachment of the sensor in 3-6 months.
⚠️ Warning: Some grey smartphones (especially models in India) have incompatible battery or camera connectors, which means that even if you find a workshop ready to take on repairs, parts will have to be ordered from abroad with a wait of up to 1-2 months.
3. firmware and updates: why gray Xiaomi might stop working
One of the most insidious differences is the firmware. Official smartphones for Russia get an adapted version of MIUI RU with:
- 📡 Support for all Russian frequencies 4G/5G (band 20 hinterland).
- 💳 The full-fledged work of Google Pay and NFC Payment for payment (in Chinese firmware) NFC frequently off).
- 🔄 Regular security updates (monthly).
Grey phones run MIUI China, MIUI Global (for Asia) or MIUI EE (for Europe), which causes the following problems:
- 🚫 Blocking your Mi Account when resetting (if the phone was tied to the previous owner).
- 📵 Lack of network in some regions (e.g. Redmi Note 11 Pro)+ 5G India does not support the Band 20).
- 🛑 Termination of updates after 1-2 years (Xiaomi often forgets about gray models).
It is especially dangerous to buy gray phones with a locked bootloader. For example, the Chinese version of Xiaomi 12S Ultra can not be reflashed to the global version without unlocking, and this requires binding to a Chinese phone number and waiting 7-30 days.
4.NFC and Contactless Payments: Why Google Pay Doesn't Work
One of the most common complaints about the gray Xiaomi is that it has a non-functioning NFC for payment, and the reason is that it has regional restrictions:
- 💳 In Chinese firmware (MIUI China module NFC physically present but blocked for payments (works only for data transfers).
- 🌐 In Global Firmware for Asia (MIUI Global) NFC may work, but banks refuse to link the card due to a discrepancy between the region of the device and the card.
- 🏦 In the official Russian firmware (MIUI RU) NFC Google Pay, Mir Pay and Secure Pay without restrictions.
Even if you manage to cheat the system and tie the card, there is a risk of sudden blocking of payments, for example, Sberbank and Tinkoff periodically check devices and can block NFC if the IMEI of the phone is not listed in the database of official importers.

5.Price: Real savings or hidden costs?
The main argument in favor of gray smartphones is the price. For example, Xiaomi 13 Pro in the official store is worth it. ~80 000 ₽, On AliExpress, you can find it for ~55 000 ₽. But is the game worth the candle? Let's calculate the hidden costs:
| Item of expenditure | Official Xiaomi | Xiaomi's grey |
|---|---|---|
| Cost of the phone | 80 000 ₽ | 55 000 ₽ |
| Warranty repair (screen) | 0 ₽ | 15 000–25 000 ₽ |
| Firmware/unlocking | 0 ₽ | 2 000–10 000 ₽ |
| Lost time for repairs | 0 | 2–4 weeks |
| Total cost of ownership (1 year) | 80 000 ₽ | 72 000–90 000 ₽ |
As you can see from the table, the real savings are only 10-20%, and in some cases, a gray phone costs more than an official one, and when resold, gray phones lose in price 30-50% faster — they are harder to sell due to lack of warranty and the risk of locking.
⚠️ Note: If you are buying a gray Xiaomi for business (for example, couriers or taxi drivers), note that banks may refuse to issue corporate cards for such devices due to the risk of fraud.
6.How to check if Xiaomi is official before buying?
To avoid running into a fake or gray machine, follow this checklist:
☑️ Xiaomi Authentication Verification
Pay special attention to IMEI. On official devices, it should:
- 🔍 Coinciding on the box, in settings (Settings) → The phone. → General information) and under the battery.
- 🌐 Check out Xiaomi’s website (if the site shows “Not found”, the phone is gray or fake).
- 📡 Support all Russian frequencies (check at frequencycheck.com).
If the seller refuses to provide IMEI for verification or claims that “all Xiaomi are the same”, you are a fraudster, and you should also be wary if the price is 30% lower than the market: most likely, it is either a refurbished (refurbished) device or a Chinese version with a locked bootloader.
💡
The only reliable way to buy an official Xiaomi is to buy it from an authorized store (list on the website). mi.com/ru/where-to-buy) or from communication operators (MTS, Beeline, MegaFon).

💡
Check the model on forums (e.g. 4PDA or MIUI SU) before buying. If the model has a theme marked "[Blockage Risk]", it is better to refuse the purchase.
