The situation when the smartphone suddenly stop running the usual programs, causes a natural irritation. Xiaomi, Redmi and POCO users often face this, especially after updating the MIUI system or switching to a new HyperOS shell. Aggressive battery optimization and strict privacy settings are the main, but not the only culprits of unstable software.
In this article, we will look at why conflicts arise, how to diagnose them without going to the service center, and what hidden settings can block Google Play or banking customers. We will look at both software failures and hardware limitations that are often ignored in the initial diagnosis.
Understanding the architecture of the Android operating system in conjunction with the manufacturer's proprietary add-on will help you quickly get the gadget back into operation.
Aggressive charge saving and background processes
The most common reason apps don’t work or crash immediately after launch is because of power saving: Xiaomi engineers implement rigid algorithms that force background processes to end up longer battery life, often resulting in messengers stopping sending notifications and navigators resetting the route.
To fix this, you need to manually configure the permissions for each critical application, the system needs to “understand” that a particular software should not be automatically frozen, and ignoring this step after updating the firmware is a classic user error.
💡
For banking apps and instant messengers, always set the “No Limits” mode in the battery menu, otherwise they may not work in the background.
The setup process is not complicated, but it requires attention to detail. You need to find a specific application in the installed list, go to the Battery section and select the appropriate work profile. Without this step, Android will consider the program to be an unnecessary load on the processor.
- 🔋 Open “Settings” and find the “Applications” section».
- 🔋 Select a problem app from the list or find it through search.
- 🔋 Go to Battery (or Saving Charge»)..
- 🔋 Set the value “No Limits” instead of “Saving Charge».
⚠️ Note: If you set the No Limits mode for dozens of games and rarely used utilities, the battery life of your smartphone can be significantly reduced.
Conflicts after the update of the MIUI and HyperOS system
Updating the operating system is always a risk of compatibility bugs. When Xiaomi releases a new version of the shell, old cached application data can conflict with new libraries, especially when switching from MIUI 14 to HyperOS, where the structure of the system files has changed.
Often users notice that widgets or certain functions within programs stop working after an update, because the application “remembers” old paths to system resources that have already changed, in which case it requires cleaning the application’s data or completely reinstalling it.
Also, some firmware versions may contain bugs that only fix in the following security patches. If the problem is massive, you may want to wait for the update or, conversely, roll back to a stable version if you have the appropriate skills.
- 🔄 Go to "Settings» → «About the phone and check for updates.
- 🔄 Try clearing the cache of a particular application through the control menu.
- 🔄 Remove and install the problem app from a reliable source.
It’s important to understand the difference between cache and data: Clearing the cache is secure and deletes temporary files, whereas clearing the data will reset the app to the “just out of the store” state by removing your logins and settings inside it.
Lack of internal memory and cache overflow
The modified Android operating system requires free space for temporary files and swaps. If the internal memory of a Xiaomi smartphone is more than 90% full, the system begins to work unstable, applications may not start, freeze during the booting stage or spontaneously close.
Social networks and instant messengers like Telegram or WhatsApp, which constantly write logs and download media files, are particularly sensitive to space shortages. When a place runs out, the operating system blocks the ability to write new data, which leads to the crash of the program.
☑️ Memory check
Use the built-in Security app or third-party utilities to diagnose, but manual checks often yield better results because they allow you to see which files are taking up space, often forgotten videos in the download folder or cache of cards.
| Type of data | Impact on work | Can be removed | Recommended level |
|---|---|---|---|
| Cash app. | High (deceleration) | Yes. | Up to 1-2GB |
| Photos and videos | Medium (lack of space) | Yes (c) | Depends on the user. |
| System files | Critical (OS failure) | No. | You can't touch it. |
| Downloads (Downloads) | Low (clutter) | Yes. | 0 MB |
Regular memory hygiene is key to stable operation, try to keep at least 3-4 gigabytes free so that the system can comfortably handle swap files.
Problems with Google Play Services and Licenses
Xiaomi’s global smartphones often have problems with Google Play Services frameworks. If these system components are incorrect or outdated, many apps will simply refuse to run, giving authorization or licensing errors, not only for app stores, but also for maps, YouTube and banking software.
Often, the problem is solved by simply cleaning up the data of the Google Play service itself, but in some cases, deeper intervention is required, such as removing service updates and re-installing the current version through the store, which helps to reset accumulated sync errors.
⚠️ Note: Do not attempt to remove Google system components through third-party deletion programs.This may lead to the "bricking" of the software part and loss of software warranty.
It's also worth checking the date and time. If they're downed, the security certificates won't be validated, and connections to the application servers will be blocked. Enable automatic time synchronization over the network.
- 📅 Go to "Settings» → «Advanced settings» → «Date and time».
- 📅 Make sure that the item "Use network time" is included».
- 📅 Check the status of Google Play Services in the app menu.
What if Google Play doesn’t work even after a reset?
Errors in the operation of a particular application
Sometimes it's not the smartphone that's the developer who's responsible, and if the app doesn't work and the rest of it works, the problem is its code or compatibility with your version of Android, and that's often the case with betas or software that hasn't been updated in a long time.
You can check the status of servers on specialized resources or in official developer channels. If everyone has a server crash, you can wait. If the problem is local, try to clean the application data or reinstall it.
It is important to download applications only from trusted sources, such as Google Play or GetApps. Installation of modified versions (mods) from dubious sites is a common cause of instability and viruses that block the work of legal software.
💡
If the app only crashes on Wi-Fi, try switching to mobile internet to see if the router or ISP is blocking access.
Conflicts of access rights and permits
Modern versions of Android and MIUI require explicit permission to access the camera, microphone, geolocation and files, and if you accidentally blocked an app from accessing the necessary resources when you install or update it, it will not be able to function properly.
For example, a navigator won't build a route without access to GPS, and a messenger won't record a voice without a microphone. Checking the permission list is a mandatory diagnostic step, and users often block access in a rush of privacy protection, forgetting about it.
Special attention should be paid to the permission to “Install Unknown Applications” and “Master Over Other Windows”, without these rights, many utilities will not be able to work fully.
- 🔒 Open the application settings and select “Permissions».
- 🔒 Check if the switches are activated in front of the desired functions.
- 🔒 Please note the section "Additional Permits».
