Owning a budget but functional Xiaomi Redmi 9A smartphone often involves optimizing the system. Sometimes users are faced with a situation when the running program stops responding to touch, the interface freezes, or the background process begins to unnecessarily consume battery power. In such cases, a standard window closing via swipe may not work, and a deeper intervention in the operation of the MIUI operating system is required.
Forced Stop is a regular Android mechanism that allows you to completely complete all the processes associated with a particular software.This action is different from conventional closure, as it clears the RAM from temporary files and interrupts all background services. For owners of Redmi 9A, knowing this algorithm of actions is a critical skill to quickly resuscitate the device without rebooting.
In this article, we will take a look at all the available methods, from simple actions through the settings menu to the use of advanced debugging tools. You will learn how to safely interrupt any software, even if the smartphone screen is completely locked.
Standard method through system settings
The safest and most recommended way to force a stop is to use the built-in Android settings menu, which does not require root rights or a computer connection and is available to every Xiaomi user.
First, open the main menu and find the Settings icon. In the settings list that opens, scroll down to the App section, which can sometimes be called All Apps depending on the version of the MIUI shell. This displays the full list of installed software, sorted by frequency of use or alphabetically.
Find the problem app on the list and click on the name, and you'll be taken to the information screen where the memory, version and access rights are displayed. That's where the key process control button is located. Click on the Stop button, which is usually located at the bottom of the screen or in the upper right corner.
⚠️ Note: The system may issue a warning that stopping the application may cause it to malfunction.This is a standard notification confirming that the process will be forcibly interrupted.
Once confirmed, all background services will be immediately terminated.If the program had desktop widgets or active notifications, they will disappear or stop updating until the next manual start-up, a method that is particularly effective for social networks and instant messengers that are prone to “bloat” in memory.
Using the special options menu
In some versions of MIUI firmware for budget models, such as the Redmi 9A, access to a full list of applications can be limited or hidden in the depth of the menu. To simplify access to stop functions, developers have provided alternative paths through the special features menu.
Go to Settings and select Advanced Settings. Find Special Options. Activate a switch here that allows you to display the special features menu on the screen. Once you turn on this feature, a floating button or icon will appear on the display that causes an additional control menu.
This menu allows you to quickly move to running processes. Although there may not be a direct stop button, this tool often allows you to get to the task manager faster, especially if the main interface of the system reacts with a delay.
- 📱 Floating window: Allows you to control volume and take screenshots without leaving the app.
- 🔍 Quick Search: Accessing settings without having to flip through long menu lists.
- ⚙️ Access control: Ability to quickly limit background activity of problematic software.
Using special features does not require technical knowledge, but it significantly speeds up access to system functions. For users, Xiaomi is a convenient tool that should be kept activated, especially on devices with a small amount of RAM.
💡
If the Stop button is inactive (gray), it means that the selected application is a system component of Android, and its stopping is impossible by standard methods without the risk of system disruption.
Forced stop when the interface freezes
The situation of an application taking up the entire screen and not responding to taps is one of the most unpleasant. On Redmi 9A with its Helio G25 processor, this can happen when you don't have enough resources. If you can't go to the desktop to open the settings, you need to use other methods.
The first step is to try to call the running app manager. To do this, swipe from the bottom up (or press the menu button if three-button navigation is enabled) and hold your finger. Find the card of the hung application and swipe it up to close. MIUI often helps long-term clicking on the application card in multitasking mode, which opens the menu with the option “Block” or “Clean”.
If the screen is completely frozen and even the controller doesn't open, all that remains is the hardware method. Press the power button for 10-15 seconds. The smartphone will forcefully restart. This won't stop the particular application, but it will clear all the RAM and complete all the processes, bringing the device back to life.
| Method | Difficulty | Efficiency | Risk of data loss |
|---|---|---|---|
| Through Settings. | Low. | Tall. | No. |
| Task Manager | Low. | Medium | No. |
| Reboot with a button | Low. | Maximum | Unsaved data |
| ADB team | Tall. | Maximum | No. |
It's important to understand the difference between swipe closing and forced shutdown. Swipe only removes an application from the recent list, but its processes can remain in memory. Forced stop via settings or restart is guaranteed to clear RAM.
Stopping System Applications and Services
Xiaomi Redmi 9A owners often want to disable pre-installed apps (bloatware) that cannot be removed in the usual way, such as Google services, theme stores or games from a partner. For such programs, the “Delete” button in the settings menu is often replaced with “Disable” or not at all.
To stop system service, go to Settings → Apps → All apps. Find the system component you want. If the Stop button is active, press it. However, for many critical Android services, this button will not be available because the system protects itself from accidental shutdown of vital modules.
Instead of stopping, use the "Disable" function, which will freeze the application: it will disappear from the menu, stop updating and consume resources, but will remain in the memory of the phone. You can always turn it back on, which is the best way to deal with unnecessary system debris on MIUI.
⚠️ Warning: Do not disable system components that you do not know the purpose of (e.g. System Interface, Download Manager) and this can lead to a cyclical smartphone reboot or loss of communication.
For advanced users, there is the option of hiding system applications through engineering menus or special launchers, but this requires caution.The standard shutdown feature in Redmi 9A is a safe trade-off between performance and stability.
What happens when the system application is disabled?
Use of debugging by USB and ADB
For those who are not afraid of the command line, there is the most powerful method of process control - the use of the Android debugging bridge (ADB), which allows you to stop absolutely any application on the Redmi 9A, even if the interface is completely blocked or the sensor is not working.
To start, you need to activate the developer mode. Go to Settings → About Phone and quickly click 7 times on the MIUI Version. After the message “You became a developer” appears, go back to the settings menu, find the Additional → For Developers section and turn on the USB Debugging Toggle.
Connect your smartphone to your computer through USB-There's got to be a platform on the computer. ADB. Open the command line and enter the command to get a list of packages:
adb shell pm list packagesFind the name of the package of the problem application (for example, com.facebook.katana) to forcefully stop it, use the following command:
adb shell am force-stop com.package.nameIt works instantly and ignores any interface locks, and it's indispensable for remote diagnosis or when the touchscreen of a smartphone is damaged, but it requires a PC and basic command line knowledge.
☑️ Preparation for work with ADB
Cache cleanup and memory management
A common reason for apps to freeze on the Xiaomi Redmi 9A is a crowded cache. Even if you stop the app, the accumulated debris can cause a failure again the next time you run. Regularly cleaning the cache is an important part of prevention.
In the app information menu (the same place where the Stop button is) is the Clean button. Select Clear Cache. This will delete temporary files without affecting your personal data, logins and passwords. If the problem persists, you can select Clear All, but this will reset the app to the state immediately after installation.
Also worth paying attention to is the built-in MIUI optimizer. Launch the Security app and press the Clean Up button. The system will automatically find and delete unnecessary files, and offer to speed up work by closing the background processes. On budget devices with 2 or 3 GB of RAM, this feature works especially well.
- 🗑️ Cash: Temporary files that can be deleted without fear.
- 📦 Data: Logins, settings and progress in games (remove carefully).
- ⚡ Memory: Free space required for a fast system.
Regular memory maintenance extends the life of the battery and makes the Redmi 9A work smoother. Do not allow internal memory to be filled to the end, leave at least 15-20% free space for the correct operation of system processes.
💡
Comprehensive approach: the combination of forced stop, cache cleaning and periodic reboot of the device gives the best result for the stability of budget smartphones.
