Xiaomi smartphone owners often face a situation where the device’s internal memory is critically filled. The system can signal a shortage of space by suggesting a standard cleanup procedure. However, many users notice that the built-in Security tool finds and suggests removing not only temporary files, but also full-fledged gaming applications or rarely used programs.
In fact, the standard MIUI optimizer (now HyperOS) doesn't delete your files without asking, it just analyzes the amount of space you've occupied and highlights programs you haven't run in a long time. Often after you upgrade or reset your system, when the algorithm scans the drive again. In this guide, we'll look at how to interpret that data correctly, how to find hidden games, and how to safely remove excess without damaging system files.
It is important to understand the difference between a cache that can be cleaned and APK installation files or apps that require confirmation. Xiaomi’s security system will never remove an app without you directly clicking on the Clean or Delete button in the appropriate menu. Confusion often arises from aggressive advertising or pop-ups that can mimic system messages. We will teach you to distinguish real system alerts from marketing tricks.
Analysis of the work of the standard application "Security"
The central element of memory and protection management in Xiaomi smartphones is the Security app, which conducts the initial diagnosis when you start cleaning. When you open this section, the system instantly scans the memory, checking for malicious code, outdated installers and a volumetric cache. If games appear on the list of candidates for removal, it means that the algorithm has classified them as “rarely used” or “take up a lot of space”.
The cleaner's functionality is divided into several modules. The Cleanup core module looks for temporary files, and the Antivirus module checks for application signatures. Sometimes the user accidentally enters the Acceleration or Memory section, where all heavy programs are displayed. Deleting applications through this interface is a standard feature that allows you to quickly free up gigabytes of space, but it requires care not to erase important data.
💡
Before mass cleaning, always check the list of files in the Recycle Bin (if included in the Gallery) or back up contacts, as some cleaning scripts may affect user data.
It’s worth noting that the interface can vary depending on the version of MIUI or HyperOS. In newer versions of the firmware, algorithms have become smarter: they can offer to archive rarely used games instead of completely removing them, which allows you to free up space on the system drive by keeping the application shortcut, which, when clicked, quickly restores the game from the cloud or reserve.
Search and Identify Hidden Games and Applications
Often users are looking for a way to remove a game they don't "see" on the desktop, but that continues to consume resources. There are several places in the Xiaomi ecosystem where applications can hide. The first place is the Tools folder or hidden desktop sections. The second is system processes that masquerade as games or have obscure names.
For an accurate search, use the built-in Application Manager. Go to Settings → Apps → All apps. This is the full list of installed software. If you see a game that is not on the screen but is on the list, then its shortcut has been removed, or it is hidden in Guest or Second Space mode.
- 🔍 Check the Hidden folder in the app menu by pulling the app list down (the gesture may differ in different shell versions).
- 📂 Use search by settings: enter the game name in the search bar at the top of the Settings menu".
- 🛡️ Run a deep scan in the Security app to see if the app is classified as potentially unwanted.
Special attention should be paid to applications with administrator rights or special permissions. Sometimes malware or aggressive ad modules can be embedded in the system and simulate gameplay. If you can't find a process in a regular list, it may be hidden in the "Special features" section or run as a system service.
How to find a process if it is not in the list of applications?
Instructions: How to properly remove the game through settings
The most reliable and secure way to remove a game or app on Xiaomi is to use the regular program management menu, which ensures that all associated files, including cache, account data, and system folder residues, are deleted. Unlike simply dragging a shortcut into the cart, this is a deeper way.
To start, open the Settings menu on your smartphone. Find the Apps (or "All Apps") section. In the list that opens, find the game you want. You can sort the list by size or name, which will make it easier to find heavy files. Click on the app name to open the control page.
☑️ Algorithm for complete deletion
On the app page, you will see the "Delete" button. If the button is inactive (gray), this means that the application is system-based and cannot be removed by standard methods without Root rights or use. ADB-In this case, the system will only suggest "Disable" the application, which will hide it and stop the processes, but will not delete the files completely.
Once you have confirmed the deletion, the system may suggest clearing the file residues, and always agree to this procedure if you are sure that you no longer need to save the game, allowing you to return an additional 100 MB to several gigabytes of free space to the disk.
Using antivirus to search for threats and debris
The built-in antivirus from Avast or AVL in the MIUI shell is a powerful tool that is often ignored. It can find not only viruses, but also applications with suspicious behavior that can masquerade as games.
To run a check, open the Security app and select Antivirus. Press "Verify." During the scan, the system checks the signatures of installed applications against the cloud database, and if a game or program is labeled as dangerous, the antivirus will prompt it to be removed or defused immediately.
⚠️ Note: If the antivirus tags a popular game as a virus, but you downloaded it from the official Google Play store, this may be a false positive.
In addition to viruses, the antivirus module often finds “privacy risks”: these are applications that request too many permissions (access to contacts, microphone, geolocation) without an obvious need, and removing such programs greatly improves the security of your personal data and prevents leakage of information.
| Type of threat detected | Operation of the system | User recommendation |
|---|---|---|
| Virus/Trojan | Blocking and offering removal | remove immediately |
| Advertising software (Adware) | Warning of intrusive advertising | Remove if the source of the advertisement is unknown |
| Risk annex | Notification of access to data | Check the permissions in the settings |
| Unknown Installator (APK) | Proposal to scan the file | Delete if the file is not needed |
Working with cache and residual files
When games are deleted, the disk often has so-called "tails" -- folders with textures, cache and configuration files -- that are searched by Xiaomi devices for in-app "Cleanup" in the Security app, scanning the Android/obb and Android/data directories to find folders with names of remote applications.
Manually cleaning through the file manager is also effective, but it requires caution. You can go to the Internal Drive → Android → obb folder. If you see a folder with the name of a remote game (for example, com.tencent.ig for PUBG), it can be safely deleted. This will free up space that the standard uninstallation may have missed.
However, be careful: deleting active game folders will result in loss of progress or the need to re-download resources (which can be several gigabytes).
What to do if the application is not removed
Sometimes users are faced with a situation where a game or application does not want to be removed, the "Delete" button may be inactive, or the process may freeze, often because the application has device administrator rights or is actively used by another process.
The first step is to revoke administrator rights. Go to Settings → Passwords and Security → Privacy → Special Permissions → Device Administrator Apps. Find the problem app on the list and uncheck. Then go back to the app menu and try to delete it again.
If that didn't work, try to put your phone in Safe Mode, which only runs system apps, press the off button, and when the menu comes up, press the "off" option (on some models), or use a volume key combination when booting, and in Safe Mode, third-party apps don't interfere with deleting them.
⚠️ Note: Do not try to remove system applications with names like "MIUI", "System Framework" or "Security Core" even if they take up a lot of space, which can lead to a cyclic bootloop and the need to flash flash it over.
Prevention: How to avoid the accumulation of garbage
To avoid future memory overload and the need to look for hidden games, it is recommended to observe digital hygiene. Regularly check the list of installed applications and delete what you have not used for more than a month. Enable automatic cache cleaning in the settings of the application "Security".
It is also necessary to limit the installation of applications from unknown sources. MIUI There is a "Installation Protection" function that checks APK-Do not ignore these warnings, as it is through third-party files that games with embedded ads and viruses are often downloaded.
Configure automatic updates of applications only through Wi-Fi to avoid downloading unnecessary data in the background. Periodic reboot of the smartphone also helps the system to reset temporary files and optimize the work of background processes.

Regularly checking the Apps section and using built-in antivirus is the best protection against hidden debris and viruses on Xiaomi.
