Xiaomi and Redmi smartphone owners often face frightening security alerts that block attempts to make a purchase in a store or app. The message that “a threat is found” or “payment is not safe” can take you by surprise at the most inopportune moment, especially when you need to pay your bill quickly. However, in most cases this is not a sign of a real virus infection, but the result of aggressive MIUI or HyperOS security algorithms, which are over-insured when non-standard certificates are detected.
Xiaomi’s security system, based on either Avast or Tencent database (depending on the region), scans traffic and apps installed in real time. If you try to use Google Pay (now Google Wallet), Mi Pay, or third-party banking apps, the system may find their behavior suspicious, especially if the device has superuser rights or a system partition has been changed. False positives are the most common cause of blocking, and ignoring this fact can lead to complete inability to use them. NFC-transaction-module.
In this article, we will discuss the mechanics of these errors in detail and provide a comprehensive guide to fix them. You will learn what settings you need to check first, how to properly configure the environment for contactless payment and whether to trust the built-in antivirus. Understanding the principles of Android Security on the Xiaomi shell will help you not only remove the annoying warning, but also really improve the level of protection of personal data.
Causes of security errors in payments
The first thing to understand is that the nature of the lock can be software-based or environment-related. Most often, the system responds to the presence of applications that can theoretically intercept keyboard data or modify system files. Root rights obtained by the user for customization are the main trigger for banking applications that refuse to work in such an environment.
The problem may also be in legacy Google Play Services or the store app itself, and if security certificates are not updated, the encryption protocol may be considered vulnerable, and in some cases, the conflict arises from installed “cracked” versions of games or programs that are embedded in system processes.
The network connection deserves special attention when you try to make a transaction over public Wi-Fi without encryption or through encryption. VPN-A low-trust service, security algorithms may view the data channel as compromised. Mi Security in this case blocks access to financial instruments to prevent leakage of card data.
💡
Sometimes, simply restarting your smartphone after a system update helps reset the cache of security certificates and eliminate false locks.
Diagnostics of the security system Xiaomi
Before we start taking drastic measures, we need to pinpoint the source of the problem. The built-in Security tool provides logs and reports that can point to a specific application or process that is causing the alarm. Run a deep scan through a standard application to rule out the presence of real threats.
Note the permissions section in the settings. It often happens that a payment application requests access to a clipboard or screen, which is regarded by the system as an attempt to read. PIN-Check what rights your banking apps and Google services have.
☑️ Primary safety diagnostics
It is important to analyze what the error occurred after, if the problem occurred immediately after installing a new launcher or screen recording software, it is likely that this component will conflict. Some remote management applications (TeamViewer, AnyDesk) can also block the launch of secure payment gateways.
⚠️ Warning: If antivirus detects a Trojan or spyware, don’t just try to delete the notification.Shoot the device off the network and do a full cleanup, as the risk of real money theft is extremely high in this case.
Set up Google Wallet and Mi Pay for a secure experience
Contactless payment requires the card emulation to work properly. In modern Android versions and Xiaomi shells, HCE (Host Card Emulation) is responsible for this. Make sure that the default payment application is selected in the NFC settings – usually Google Wallet or Mi Pay.
Often users forget to add an authentication method. NFC-Payments must be installed lock screen using PIN-Without it, card tokenization won't work, and the system will give you a security error.
If you use Mi Pay, make sure that the region in the Mi Wallet app matches the region of the card issuer, in some cases, removing the card from the application and re-additioning it after cleaning the service cache helps.

Resolving conflicts with Root rights and modifications
If your smartphone has an unlocked bootloader (Unlock Bootloader) or a Magisk Root right installed, banking apps will not start by default.The Google Play Integrity security system (formerly SafetyNet) flags the device as unsafe.
Using Magisk Hide or Zygisk allows you to exclude certain applications from the list of those that see the rights of the superuser. However, banks are constantly improving detection methods, and simple configuration may not be enough, in such cases, it is recommended to use patches or specialized modules to bypass the checks.
It’s worth noting that having a customized recavator (TWRP) can also trigger protection. If it’s critical for you to use banking applications, consider returning to stock firmware and bootloader shading, although this will make it impossible for you to customize.
| Type of modification | The risk of blocking | Bypass method | Stability of work |
|---|---|---|---|
| Unlocked loader | High-pitched | Magisk Hide / Shamiko | Low (requires updates) |
| Installed by Magisk | critical | Magisk cover-up (DenyList) | Medium |
| Custom recovery | Medium. | Temporary drainage return | High (after return) |
| Third-party launchers | Low. | Permit settings | Tall. |
💡
Having a Root on a device is a voluntary waiver of bank security guarantees, and it is becoming increasingly difficult to hide them from modern security systems.
Working with antivirus software and cleaning the cache
Xiaomi’s built-in antivirus sometimes fails in the heuristic analysis. If you are confident in the security of the application you are installing (for example, this is the official APK from the bank’s website), you can add it to the exceptions. To do this, go to the Security app, select Antivirus, click on the settings (cogs) and find the exception list.
It is not superfluous to clear the cache of Google Play services and the Google Wallet application itself. Accumulated temporary files may contain erroneous data about the security status of the device.
If you use third-party antiviruses (Kaspersky, Dr.Web, ESET), make sure their web protection modules do not conflict with Xiaomi's system monitoring.
⚠️ Note: Adding apps to the antivirus exceptions reduces the overall level of protection.
Prevention and Update of System Components
Regular system updates are the best way to avoid security issues. Xiaomi periodically releases patches that close vulnerabilities in the work NFC-module and payment gateways. Check for updates in Settings → The phone. → Version. MIUI.
Also keep an eye out for updates to Google Play Services, which is the component that handles interactions with Google's security servers, and the older version may not support the new encryption protocols required by banks.
Remember to check the list of devices authorized in your Google account regularly, and if you see unfamiliar gadgets, change your password immediately and perform two-factor authentication, which will prevent malicious users from accessing your payment data even if one of the devices is compromised.
