If you have one in use or are thinking of getting one for a very low price, Please note that they will not receive new security patches or system updates.In many cases, due to age and safety concerns, it may be worth considering a newer model.

Besides knowing if your phone is still supported, it can be very useful to verify that All physical components of the device are functioning correctly.: screen, sensors, microphones, vibration, connectivity, etc. Xiaomi offers a hidden menu in MIUI designed precisely for this type of testing.
This is the so-called CIT menu, a menu of hardware tests integrated into Xiaomi's own ROMThis feature is present on most Xiaomi, Redmi, and POCO phones, and even models like Black Shark that use MIUI or its derivatives. It's a hidden but safe menu: you can access it without fear because it doesn't alter the system settings if you only run the tests.
The CIT menu offers different types of tests, which may vary from model to model. In all cases, It will allow you to quickly check if each component passes the test correctly.You will see instructions in English and, depending on the result, you will have to mark whether the test is correct (pass) or if it has failed (fail).
Accessing the hardware check menu on your Xiaomi is relatively simple, although it's somewhat hidden. You can access it from the system settings by selecting a hidden option in the device information section.
To open the CIT on most mobiles with MIUI, Follow this basic process from your Xiaomi settings:
- Open the Settings app on your Xiaomi device. y go to the "My Device" section, which usually appears at the beginning of the menu.
- After Tap on "All specifications" to see the complete technical specifications of the phone.
- Within that screen, locate the line called "Kernel Version" and Tap it five times quickly and in succession..
After doing those pulses, The CIT menu, the secret hardware testing panel, will open automatically.From there you will see a list of components (screen, sensors, cameras, vibration, etc.) or, in some models, an automatic test button that runs several checks in sequence.
Once inside the menu, You can start the tests manually by tapping on each component and following the on-screen instructions, or using the automatic mode if your CIT includes it. During the tests, the phone will ask you to interact with the screen, press physical buttons, speak into the microphone, or move the device to verify sensors.
If you see a "pass" result at the end of the test, it means that That component responded correctly in the testIf a "fail" appears, there is likely a hardware failure or abnormal behavior that should be checked at an authorized service center, especially if the phone is still under warranty.
How to check if a used Xiaomi is unlocked

If you're considering buying a used Xiaomi, in addition to support and the condition of the hardware, there's one important detail: Check if the phone has an unlocked bootloader and confirm that it is not locked by a Mi account.This can save you a lot of trouble later on.
In MIUI's developer settings, you'll see an option called "OEM unlocking," which allows the bootloader to be unlocked, but The mere fact that that box is checked or not does not in itself confirm the actual state of the bootloader.It's more of a prerequisite than a definitive indicator.
The most reliable way for the average user, directly from their phone, is Go to Settings > Additional settings > Developer options and look for the section related to the Mi unlock status or bootloader status.In many models, it is clearly indicated whether the device is locked or unlocked when linking the Mi account for the unlocking process.
Another technical method, if you are familiar with ADB and fastboot tools, involves Boot the phone into fastboot mode and use the fastboot command to check the lock status.This requires a computer, drivers, and some experience, but it's the standard method used by advanced users.
What is neither practical nor advisable as a first step is to perform a factory reset just to see if After formatting, the phone asks for the password of the previous My account.This also involves deleting all data, so it should only be done if you have already verified with the seller that there is no account block and that they will provide you with their credentials or log you out correctly.
What to check when buying a used Xiaomi
When buying a used Xiaomi, it's a good idea to give the phone a quick "MOT" check to avoid any surprises. Beyond aesthetics or battery life, There are several key points related to device support, authenticity, and security.
On the one hand, you should check in the Xiaomi Security Center whether the model is still within the support period and that Check using the CIT menu that all hardware components are responding correctlyThis helps you detect screen, connectivity, or sensor problems that might not be visible to the naked eye in just a few minutes.
It's also important to verify that the seller has unlinked the phone from their Mi account. To do this, Ask him to show you the phone without it being linked to any Xiaomi account. (in Settings > My Account) and, if possible, have them log out in front of you. If you buy the device already reset, it shouldn't ask for someone else's credentials when you turn it on.
Additionally, whenever possible, do a quick IMEI check on the Xiaomi website to verify. that the device is authentic and that it is not an unofficial product or imported through dubious channelsThat gives you more guarantees when using technical support in case of problems.
Xiaomi's official warranty: what it covers and how long it lasts
Another key aspect of Xiaomi's support is the official warranty. The brand offers a contractual warranty for the hardware of its products, independent of the minimum legal warranties required by the law of each countryIn other words, you have the protection required by law, plus the additional coverage that Xiaomi provides voluntarily.
For many products sold through official channels, Xiaomi offers a warranty of three years from January 1, 2022 for devices purchased from that dateUnless local law mandates a different or longer period, this voluntary warranty covers defects in materials and workmanship under normal use of the product.
The company makes it clear that It cannot guarantee that the use of the product will always be uninterrupted or error-free.However, it does commit to repairing, replacing, or refunding the price of the device if a hardware defect is detected within the warranty period and a valid claim is submitted.
