Chinese tech giant Xiaomi has captured a significant share of the global market in recent years by offering devices with impressive specs at a price that seems impossible for competitors. Consumers from around the world are massively switching to Redmi and Poco, believing they have found the perfect balance between functionality and cost.
Many enthusiasts who have bought their first smartphone of the brand face a number of unpleasant surprises that are not reflected in marketing brochures. From intrusive advertising in the system to problems with global versions of firmware, the list of claims grows every year. In this article, we will discuss in detail why you should not buy Xiaomi phones if you value stability, privacy and the absence of unnecessary digital noise.
Analysis of the user experience and technical features of MIUI and HyperOS allows you to identify systemic problems inherent in almost all models of the brand, from budget to flagships. Understanding these nuances will help you make an informed decision and, possibly, save nerves and money in the future.
Aggressive advertising integration into the shell
One of the main reasons that power users recommend against buying Xiaomi is advertising. Unlike competitors who make money selling devices, Xiaomi has historically laid a margin in software services, turning the smartphone interface into an advertising platform. Even in expensive models, you can encounter recommendatory banners in standard applications.
Ad units are embedded in system utilities such as Explorer, Music and Security, and users are forced to either put up with visual noise or spend hours manually disabling all advertising identifiers and settings in the depths of the menu, which creates the feeling that you are not using your gadget, but a rented device with restrictions.
Making matters worse, after major MIUI updates, some privacy settings may be reset and the adverts return, requiring the owner to be vigilant and technically skilled to keep the system clean.
- 📢 System Apps: Advertisements appear in the standard calendar, weather and even when installing apps.
- 🔒 Disabled Difficulty: To remove all ads, you need to change more than 15 different settings in different menu sections.
- 📉 Performance Impact: Advertising modules consume processor and RAM resources, slowing down the interface.
⚠️ Note: Even after buying Xiaomi’s flagship series, you are not immune to pop-ups in app folders unless you turn off the “Get recommendations” feature in each folder’s settings manually.
Problems with global versions and Band 20
A second critical aspect that is often overlooked when ordering smartphones from China or even buying from local stores is the support of communication frequencies. Many models, especially in the low-end and mid-range segments, are released in the Chinese version, which is reflashed by the seller on Globalka. These devices often lack Band 20 (800 MHz) support, which is critical for high-quality 4G/LTE reception in rural areas and outside the city.
Buying such a device, you risk getting a device that will catch the network in the city, but outside the metropolis will slide to EDGE or completely lose the signal. Moreover, overstuffed versions can have problems with the work of NFC, banking applications and Android Pay (Google Pay), because the integrity of the system is broken.
The official global versions are free of these frequency issues, but they are much more expensive, negating the main advantage of the brand – price, and even in official global firmware, there are sometimes localization errors or broken services Google in certain regions.

Instability of software and MIUI bugs
The MIUI shell, and now the new HyperOS, has long been notorious for being oversaturated with features that often run insecurely. Users regularly report spontaneous reboots, interface freezes and application background problems. In pursuit of more features, developers often sacrifice code optimization.
The problem with notifications is particularly acute: Xiaomi’s aggressive energy saving system often “kills” the processes of messengers and email clients, causing notifications to arrive with a delay or not at all, and the user has to manually add every important application to exceptions and whitelists, which in 2026 looks archaic.
Frequent firmware updates that should solve problems sometimes bring new ones. History has known many cases when after updating Settings → About the phone → Updating the system, users quickly began to run out of batteries or stopped working Bluetooth.
- 🐞 Interface bugs: Animations can slow down, and menus will not respond to touch.
- 🔋 Energy saving: the system too aggressively closes the background applications, violating the logic of the message.
- 🔄 Update errors: New versions of software often contain critical vulnerabilities or bugs that require waiting for a patch.
⚠️ Warning: If you plan to use your smartphone for mission-critical tasks where you can’t lose notification or allow a failure, instability MIUI It can be a serious obstacle to work.
Comparison with competitors: where the benefits are lost
To judge why Xiaomi should not be bought, you need to compare it to direct competitors in the same price segment. If Xiaomi was king (price-to-quality ratio), now the difference is blurred. Other brands have learned to make quality devices, while offering cleaner Android and better support.
The table below compares the key aspects of using Xiaomi smartphones and their competitors (e.g. Samsung, Motorola or Realme in certain lineups).
| Criteria | Xiaomi / Redmi / Poco | Competitors (Samsung/Motorola) |
|---|---|---|
| Cleanliness of the system | Lots of pre-installed garbage and advertising | Pure Android or Minimum Changes |
| Support for updates | Often delayed or stopped early | 4-5 years of guaranteed security updates |
| Stability of communications | Depends on the version (issues with Band 20) | Full support for all local frequencies |
| Liquidity | It was getting cheaper in the secondary market. | Longer to hold the residual value |
As the comparison shows, the savings when buying Xiaomi are often illusory, given the loss of value of the device on resale and the time spent setting up.
💡
The initial low price of Xiaomi’s smartphone is often offset by a rapid loss of market value and the time it takes to fix software flaws.
Quality of assembly and materials in the budget segment
In the pursuit of high numbers in benchmarks, Xiaomi often saves on the physical components of the device. In the budget models of the Redmi Note or Redmi A series, you can find low-angle screens, plastic frames that creak, and cameras that shoot well during the day, but at night turn photos into porridge.
The vibrator's quality is also often poor, as it hums rather than gives a clear tactile response, speakers can wheez at maximum volume, and GPS modules can scour satellites for a long time or work inaccurately, all of which together create a sense of cheapness.
In addition, there are problems with quality control in factories: the percentage of defects or devices with “floating” build quality (for example, uneven screen illumination or backlight buttons) Xiaomi is statistically higher than market leaders.
- 📉 Screens: Cheap models are often used TFT cheap IPS low-brightness.
- 🔊 Sound: Monophonic sound or stereo with strong channel imbalance.
- 🔋 Battery: Real capacity is often lower than claimed, and degradation occurs faster.
⚠️ Note: When buying, pay attention to the type of screen array. TFT or IPS (LCD) with a low frequency of sensor survey, do not expect smoothness and juiciness of colors, as on the AMOLED.
Telemetry collection and confidentiality issues
The issue of privacy is becoming increasingly urgent, with Xiaomi, like many Chinese companies, accused of collecting excessive amounts of user data, collecting telemetry, browsing history, location data and app usage habits.
While the company claims to comply with international security standards, the fact remains that your data is processed on servers whose jurisdiction may differ from yours, which is becoming a red flag for users who value anonymity.
Disabling data collection is almost impossible without the use of advanced methods of system modification, such as obtaining root rights or installing custom firmware, which deprives of guarantees and complicates the use of banking applications.
💡
To minimize data collection immediately after turning on your smartphone, turn off the Internet, go to your Mi Account settings and opt out of all user experience agreements before connecting to Wi-Fi.
Resume: who exactly should not take Xiaomi
To sum up, Xiaomi phones are a trade-off: You get powerful hardware for less money, but you pay for it with advertising, unstable software, and privacy questions, and it's for enthusiasts who are willing to pick up on the settings, but not for ordinary users who want to buy and forget.
If you want a phone for parents, children or as a work tool where reliability and predictability are important, it's best to consider alternatives.The market is crowded with devices that work more stable out of the box, even if they cost a little more.
Ultimately, the decision to buy or not to buy is yours, but now you have the information about the hidden sides of the popular brand.
