Xiaomi Redmi Note 8 Pro Release Date: How to Find out the Year

Determining the exact time of production of a smartphone is often critical when buying a device on the secondary market or when you need to contact a service center. Xiaomi Redmi Note 8 Pro, released in 2019, is still very popular thanks to its powerful processor and quality camera, but finding a completely new instance is becoming increasingly difficult. Buyers often confuse the date of release of the model to the global market with the actual date of assembly of a particular device that could have been in stock for several years.

Knowing the real age of a gadget helps you estimate the residual life of a lithium polymer battery that degrades even without active use. In addition, this information is necessary to verify the originality of the device, since unscrupulous sellers can pass off restored or assembled from substandard parts of devices for new ones. In this article, we will discuss in detail all the available ways to obtain reliable data on the “birth” of your phone.

There are several methods of obtaining this information, from simple visual inspection of the box to the use of special engineering codes and checking for a unique IMEI identifier. The serial number of the device encoded in IMEI is the most reliable source of information about the production date. Some methods require a connection to a computer, others are available directly in the settings menu. We will review each of them so that you can choose the most suitable option.

Analysis of factory packaging and labelling

The easiest and fastest way to know the age of the device is to carefully examine the original box in which the smartphone was supplied. On the side or back of the cardboard packaging, the manufacturer always places an information sticker with specifications and production data. Look for a line that says Date or Mfg Date, which usually shows the month and year of release in MM.GYG or MM/GY format.

However, the date on the box indicates the time of packing a particular instance, not the beginning of sales of the entire line. If you buy a phone with your hands without a box, this method becomes unavailable, and you will have to resort to software. Also pay attention to the integrity of the sticker: if it is glued or looks suspicious, this may indicate that the device was collected in an unauthorized service.

It is important to distinguish between the global version and the Chinese version, as the labeling may differ. The Chinese boxes often have a more complex hieroglyphic inscription, but the dates are usually duplicated in Arabic numerals. If the box has a date that is significantly different from the official model presentation date (August-September 2019 for the Redmi Note 8 Pro), this may mean that you are in front of a late batch device or a restored device.

⚠️ WARNING: If there is no production date on the box at all or the sticker is crooked on top of another, this is a sure sign of counterfeit packaging. Xiaomi's original products always have a clear and even printing.

For those who have kept the documentation, it may be useful to examine the warranty card, the date of sale indicated on the check or warranty card indirectly confirms the age of the device, if more than three years have passed since the purchase, and the battery has not changed, its capacity may decrease to 70-80% of the original.

Use of the engineering menu and USSD-code

Android, which underlies the MIUI shell, has a special diagnostic menu hidden through a set of specific digit combinations. For Xiaomi devices, one of the most informative codes is ##6484##, which opens the CIT (Customer Inspection Test) menu. There is a lot of technical data available here, although a direct release date may not be displayed in all firmware versions.

A more reliable method for getting detailed information is to use the code ##4636##. Once in the Test menu, select Phone Information. Scroll down to Statistics or Assembly Information. This often displays the firmware compilation date, which usually coincides with the period (delivery) or pre-sales preparation of the device.

• 📱 Enter the code ##6484## in the Phone app to log into the full engineering menu.
• 🔍 Find the "Version" or "Summary Information" section, where the date of the software assembly can be indicated.
• 📅 Compare firmware build date to model release date: if firmware is older than phone release date, it’s weird.
• 🔌 Don’t be afraid of the many tests in the CIT menu – just use it to view information without running hardware tests without the need.

It is worth noting that on some global firmware, access to certain engineering menu items may be restricted by the manufacturer for security reasons. If the codes are not working or the menu is empty, try using alternative methods described below. Also remember that resetting the settings to factory does not change the production date, but can update the installation date of the software.

Use of the USSD-It's a quick way to get the initial information about the state of the system, but if you need the legally relevant data for the guarantee, you'd better go to the official sources of the check.

Checking by IMEI through official services

The most accurate and official way to know the release date is to verify the unique device identifier - IMEI (International Mobile Equipment Identity), which is assigned to each phone during production and contains encrypted information about the model and lot. For the Redmi Note 8 Pro, you can use the official Xiaomi verification site or third-party authoritative databases.

To find out your IMEI, dial the *#06# code or look at the sticker under the back cover (if it is not removable, then on the box). By entering this 15-digit number on mi.com/global/verify or a similar regional portal, you can see the warranty status and, often, the date of activation of the device. The first activation date almost always coincides with the date of purchase or start of use, which gives an accurate understanding of the age of the gadget.

There are also third-party services like imei.info that provide detailed information about the device, including the estimated production date. These databases aggregate information from operators and manufacturers. Although they are not official, their accuracy is high enough for household purposes. Type IMEI into the search box, and the system will give a report where the model year and sometimes a specific month of release will be indicated.

When using third-party sites, be careful not to enter your personal data other than the IMEI number itself. Xiaomi's official website is the most preferred option, as it is directly linked to the company's device activation servers.

Applications for detailed diagnostics

If Android’s built-in tools don’t seem informative enough, specialized apps from the Google Play store will come to the rescue, led by Device Info HW or AIDA64, which reads data directly from system files and hardware registers, providing a complete picture of hardware and software.

Once you install an application like CPU-Z or AIDA64, launch it and go to the Device or System tab. Look for the Build Date or Manufacture Date fields. Although this is the compilation date of the installed operating system, it is often very close to the date of the smartphone, especially if the phone has not been reflashed. The difference is usually several weeks or months.

⚠️ Note: Apps show the build date of the current firmware. If the phone has been reflashed or updated manually, this date will change to a newer one and will not reflect the actual age of the hardware».

The advantage of using applications like AIDA64 is that you can export the report, you can save the information to a text file or send it to your own mail, which is convenient if you buy the phone remotely and the seller can send a screenshot or a file with characteristics to confirm the year of release.

In addition, these apps show the actual state of the battery, the number of recharge cycles (if the battery controller supports this information) and the current temperature of the components, all of which together give a complete picture of how intensively the Redmi Note 8 Pro was used.

Decoding of model code and serial number

For advanced users, information encoded in the serial number itself or model code may be interesting. While Xiaomi does not use the same transparent system of encoding dates in serial numbers as Samsung or Huawei, certain patterns are still traceable. Often the first digits of a serial number may indicate a year and a week of production, but this information is not standardized for public access.

The Redmi Note 8 Pro is coded M1906F7SH (for global version) or M1906F7SH (for China, variants may differ in the last letter). Knowing the model code, you can accurately determine the destination region and approximate release period of this modification. Global versions began to come out later than the Chinese, usually with a delay of 1-2 months.

• 🌏 The Global version usually has code ending in letters that distinguish it from the Global version. CN version.
• 📦 The Indian version can have a separate model code and be produced in local factories, which affects the release date.
• 🔢 The serial number is unique for each device and is used for tracking in the databases of service centers.
• 📝 Write down the full model code before buying parts, as the layout of internal modules may vary.

If you see a device with a model code that does not match the declared region (for example, the Chinese version with global firmware, hand-stitched), this can create problems with notifications (Push notifications) and the operation of some banking applications (NFC, Google Pay).

💡

When buying a used Redmi Note 8 Pro, pay attention to the presence of a “yellow triangle” in the settings menu – this is a sign of an unlocked bootloader, which is often found on devices that have been in repair or re-flashed by enthusiasts.

Frequent questions and problems of determining the date

When searching for information, users often encounter conflicting data, such as the IMEI site showing one date and another in the engineering menu, which is normal because the sources of information are different, the site shows the date of first registration on the network, and the menu shows the date of the software build. Priority should be given to the date from the official IMEI database, since it records the beginning of the life cycle of the device for the end user.

Another common problem is the lack of data in the database. If you typed in the IMEI of a new or rare device and the site says "not found," don't panic. The database doesn't update instantly. For the Redmi Note 8 Pro, given its age, the data should be on the system long ago. The lack of record may indicate that the phone is assembled from parts or has a modified (cloned) IMEI, which is a sign of an illegal device.

To sum up, the best way to accurately determine the release date of the Xiaomi Redmi Note 8 Pro is to use a comprehensive approach: compare the data from the box, IMEI checks on the official website and information from the engineering menu. Only a combination of these factors will give you a complete and objective picture of the history of your smartphone, avoiding buying an illiquid or refurbished device at the price of a new one.
