Owners of Xiaomi Redmi 8 Pro smartphones periodically face a situation when their favorite game or work messenger suddenly closes, returning the user to the desktop. This annoying phenomenon, known as a “crash” or drop-off of an application, can significantly reduce productivity and spoil the impression of using the device. The problem often lies not in hardware malfunction, but in software conflicts or incorrect allocation of system resources.
The modern shell MIUI, installed on smartphones, has many background processes that aggressively control memory to save battery power. This feature often causes the forced shutdown of running programs. Understanding the operating system of Android in conjunction with the manufacturer's proprietary add-ons will help to effectively diagnose and troubleshoot the problem without contacting the service center.
In this article, we will look in detail at the algorithms that will help stabilize the software. We will touch on the issues of cleaning system debris, setting up developer parameters and working correctly with cache memory. A competent approach to maintaining your gadget will allow you to forget about sudden closures of the interface.
Analysis of the causes of unstable work of the software
The first step is to understand what is causing the failure. The most common cause is a lack of RAM. The Redmi 8 Pro, although it has enough memory for most tasks, can have difficulty running heavy applications at the same time. When the free resource is exhausted, the system forcibly completes processes it considers less important.
Another critical factor is crowded cache: temporary files accumulate during use and over time can be damaged or conflict with new versions of programs. Damaged cache files are responsible for more than 60% of spontaneous crashes in games and social networks.
After updating the Android operating system or the MIUI shell, some applications may not work correctly if their developers have not released the corresponding compatibility patch, in which case the departure occurs immediately after launch or at the time of accessing certain functions.
⚠️ Note: If the application crashes immediately after installing the system update, do not rush to make a full reset. Often developers release a hotfix within a short time. 2-3 days.
You can use the built-in logging tools to make a precise diagnosis, but for the average user, it's more informative to look at the device's behavior patterns: Does the program only fly when Wi-Fi is connected? Does an error occur when the charge level is low? These details will help narrow the search.
Basic cleaning and memory management
The standard cleaning tool in Xiaomi is quite effective, but requires proper use. Don’t just press the “Clean” button, go to the deep storage settings. Deleting downloaded files from the messenger folders (especially WhatsApp and Telegram) can free up gigabytes of space, which will positively affect the speed of writing temporary files.
Special attention should be paid to the forced stop of the problem application. This action resets the current process in memory, eliminating the hanging scripts. To do this, go to the Settings menu → Apps → All applications, find the desired software and click the Stop button. After that, it is also recommended to clear its cache without deleting user data, if you do not want to lose logins or settings.
☑️ Checklist of fast optimization
Regularly restarting your device isn't just about turning off your screen, it's about cleaning your RAM from system debris. If you're used to keeping your smartphone off for weeks, it's inevitable that you'll have errors accumulating in your system libraries. A weekly reboot helps reset the state of Google Play Services and MIUI background processes.
Let’s look at the main optimization areas that are worth checking first:
- 📱 Checking free space on the internal drive (at least 15% of the total volume).
- 🔄 Update all apps through the Google Play Store or GetApps.
- 🚫 Disabling automatic application updates in the background during active play.
- 🔋 Checking the energy saving mode, which can aggressively "strangle" background processes.
Configure MIUI optimization and battery
MIUI is famous for its aggressive energy-saving policies, which often go against the user's desire to keep applications running. The system can "kill" processes that it considers inactive, even if you just switched to another window. To prevent a particular application from crashing, you need to add it to exceptions.
Go to Security → Battery (or just Settings → Battery in new versions). Find the right app in the list and change the mode to No restrictions. This will prevent the system from forcibly stopping the process even if the screen is turned off or another program is running. Also make sure that the autostart option is enabled if the application needs to receive real-time notifications.
Another important parameter is memory expansion. Some firmware versions for the Redmi 8 Pro have a feature that allows you to use part of your internal memory as virtual RAM. While this can help with multitasking, using this feature too much on older drives sometimes leads to slowdowns and instability. Try turning this option off in your memory settings if you notice lags.
Remember, Memory Extension, if it's activated, it uses slow flash memory to store data that didn't fit into the fast memory. RAM. For some of the heavy ones 3D-This can be a critical factor in departures, since the speed of reading data from virtual memory is lower than the game engine requires.
⚠️ Warning: Setting “No Limits” mode for a large number of applications can lead to accelerated battery discharge during the day.
Working with cache and application data
When simple methods don't work, you need to do more intrusion into your application files. Cache cleaning is a secure operation that deletes temporary files but doesn't affect your accounts and saves. However, if the problem is a damaged database inside the application, you'll need to clean all the data. Before doing this, make sure that your game progress or correspondence is synced to the cloud.
You can do this through the Settings menu → Apps → All apps. Select a problem program, go to the Warehouse section and click Clean. If you choose Clean All, the app will return to state immediately after installation. This often solves problems with Instagram, Viber and heavy online shooters.
There's also a hidden section for managing system components. The Developer menu (how to turn it on, see below) has a section called "Inactive Apps," where you can see how much resources programs you're not using right now are consuming. Forced shutdown of Google or MIUI system services can temporarily fix the problem, but the system will run them again if necessary.
Let’s compare the cleaning methods:
| Method | What's removed | Impact on the account | Recommended frequency |
|---|---|---|---|
| Clearing the cache | Temporary files, thumbnails | No influence. | Once a week. |
| Clearing the data | Settings, logins, databases | Re-entry required | Critical errors |
| Reinstallation | All application files | Re-entry required | If nothing helps |
| Resetting settings | All the information on the phone. | Total loss of data | As a last resort. |
Hidden cache folders
Advanced settings for developers
For advanced users, Xiaomi Redmi 8 Pro gives access to the developer menu. To activate it, you need to quickly click 7 times on the build number in the About Phone section. After the message "You became a developer" appears, a new item will appear in the settings menu.
Inside the "Developers" section, we're interested in the "Applications" block. Here you can find the "Do Not Save Activities" option. If it's on, the system will destroy the application as soon as you roll it up on the desktop. Make sure that this switch is turned off. It's also worth checking the background limit: set a value to "Standard Limit" or "No More than 4 processes" so that the system doesn't have too much memory.
💡
Use Strict Mode in the developer settings to see visual indicators for long-term operations in the main stream, which will help you understand which application is loading the system.
Another useful feature is to disable MIUI optimization. At the bottom of the developer menu (you need to click on "Enable MIUI optimization" several times to appear on the confirmation menu), you can temporarily disable optimization. This action often helps if departures are associated with a conflict of branded add-ons and pure Android code.
It’s important to keep in mind animation options. Although they don’t directly affect code stability, setting the animation scale to zero or 0.5x creates the illusion of faster performance and reduces the GPU load when switching between windows, which indirectly affects overall interface responsiveness.
System update and software reinstallation
If software failures are massive and affect different applications, the problem may be the operating system itself. Check for updates in Settings → About Phone → MIUI Version. Xiaomi regularly releases security patches and bug fixes that can directly solve the stability problem.
In cases where the update does not help or the system is unstable after the update, a complete factory reset may be required.This is a radical method that deletes all user data.Be sure to back up your contacts, photos and documents in the Google cloud or on your computer before starting the procedure.
To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The device will reboot and start a cleanup process that can take 5 to 15 minutes. Once turned on, the phone will be as new and you will have to reconfigure accounts and install apps. This ensures that any hidden file conflicts are deleted.
⚠️ Before you reset completely, make sure you remember the password from your Mi Account and Google account, otherwise the phone may be locked after the reset due to the security feature.
💡
Full reset eliminates 95% of the program errors associated with departures, unless the problem is caused by a physical malfunction of the memory or processor.
