Owners of Xiaomi’s popular budget smartphone Redmi 4A often face the challenge of filling up internal memory, exacerbated by the mysterious “Other” category, which can take up gigabytes of precious space without being subjected to standard cleaning through the storage management menu, a system partition that accumulates temporary data, app cache, remnants of remote programs and system logs that the MIUI shell cannot automatically classify.
Ignoring this problem causes the device to slow down, errors in installing updates, and the inability to upload new photos or messages. System debris accumulates gradually, and if you do not regularly prevent the phone from working unstable. In this article, we will detail the proven methods that will help you safely get rid of excess ballast and return the device to its previous speed.
Memory analysis and diagnosis of the problem
Before you start taking drastic action, you need to understand what exactly occupies space on your Redmi 4A. Standard Android tools don’t always correctly display the file structure, so the first step is to use the built-in analyzer. Go to the settings and select Memory, where the system will try to visualize the data distribution.
However, it often happens that the category “Other” is inflated due to indexing errors or specific behavior of some applications, such as messengers or browsers. Cache data can weigh more than the programs themselves, creating the illusion of lack of space. For deeper analysis, it is recommended to use third-party utilities that show the real picture of the file system.
- 📊 Standard analyzer MIUI It only shows the big picture, hiding the details.
- 🔍 Third-party file managers can find hidden folders with garbage.
- 📱 Messengers often store media files in shared folders, enlarging the “Other” section».
⚠️ Note: Do not manually delete system files with unknown names through the root conductor if you are not sure of their purpose.This may cause the operating system to malfunction and require the device to be flashed over.
It’s important to distinguish between user data and system files. If you see the Other grow dramatically after installing a particular program, the problem is likely to be that. On Redmi 4A, with its limited internal storage (often 16 or 32 GB), even 1-2 GB of garbage makes up a significant portion of the available space.
Use of the built-in “Cleanup” application
The MIUI shell installed on the Xiaomi Redmi 4A comes with a powerful built-in system optimization tool.This is the first tool worth looking at, as it is secure and integrated at a deep level. Launch the Security app and select the Cleanup section.
The system will analyze the device and suggest removing temporary files, app residues and advertising debris. However, standard cleaning is often superficial. To get to the deeper layers, click on the garbage icon and wait for the scan to be completed. After that, click the Clean button, but do not rush to close the window.
☑️ Checking before cleaning
For more thorough cleaning, additional categories are often hidden in the cleaner menu. Click on the settings icon or three dots in the corner of the screen to find the Deep Clean option. Here you can find large files, duplicate photos and unused ones. APK-files that may also be classified as “Other».
- 🧹 Automatic cleaning removes only the obvious cache.
- ⚙️ Manual verification allows you to select specific file types to delete.
- 📂 Duplicate search helps free up space occupied by copies of images.
Regular use of this tool helps keep the system clean, but if the volume of the Other has not decreased significantly after all the procedures, more advanced methods will be required. Automated cleaning scripts can not always reach the specific logs of some applications.
Cleaning the cache of applications and user data
The main source of the Other category growth is app data. Social networks like Telegram, Viber and WhatsApp store a huge number of temporary files that the system perceives as unclassified garbage. To solve this problem, you need to go to the settings of each heavy application separately.
Go to Settings → Apps → All apps. Find the most extensive programs (usually sorted by size) and go to the app properties and you will see two buttons: Clear and Delete. Be careful: the Clean button only removes the cache, which is safe. The Erase Data button will reset the app to the state immediately after installation, removing logins, correspondence and settings.
What's Dalvik Cache?
Special attention should be paid to browsers. They accumulate gigabytes of history, cookies and page cache. In the browser settings (Chrome, MIUI Browser), find the Privacy section and clean up the history and cache. This action often frees up hundreds of megabytes that were previously listed in the Other section.
- 💬 Messengers store the received photos and videos in hidden folders of cache.
- 🌐 Browsers accumulate site data to speed up page loading.
- 🎵 Streaming services retain buffered track data.
⚠️ Before clearing the data of messengers, be sure to back up the correspondence in the cloud (Google Drive or iCloud), otherwise you will lose the entire message history without the possibility of restoring it.
Working with the file system through PC
If the software methods don't produce the desired result, the most effective way is to manually analyze the file system via a computer. 4A PC-only USB-cable and select file transfer mode (MTP). This will allow you to see the folder structure as it really is.
On your computer, create a temporary folder and copy all the contents of the phone's internal memory. After copying, format the phone's internal memory (making sure the backup is done!) or manually delete suspicious folders. Often, at the root of the system, you can find folders with the names of applications that have been deleted long ago, which continue to store their data.
Look for folders called Android/data and Android/obb. They can contain heavy files of games and programs. Also check the DCIM/.thumbnails folder, which stores thumbnails of your photos, which can grow to incredible sizes and not be deleted by standard means.
💡
Use WinDirStat or TreeSize Free on your computer to visually analyze your connected phone, and these tools will show you which folders take up the most space, in the form of a color map.
After removing the excess debris, remember to copy important user files (photos, documents) back to your phone. This method requires caution, but it is the most effective method for fighting stubborn files that do not want to be deleted otherwise.
Resetting to factory settings (Hard Reset)
When none of the above methods work and the Other category continues to occupy a critical amount of memory, the radical but effective solution remains: a complete device reset, which will return your Redmi 4A to the state out of the box, completely destroying all user data and system debris.
Before starting the procedure, be sure to save all important contacts, photos and files to an external memory card or to the cloud. Reset will delete absolutely everything: applications, settings, accounts and files. To perform the reset, go to Settings → Advanced Settings → Restore and Reset → Reset.
The system will ask for a confirmation of action and password from your Mi Account for security. Once confirmed, the phone will reboot and begin the cleaning process, which can take from 5 to 15 minutes. Upon completion, you will receive a clean system where the category "Other" will occupy the smallest possible volume.
⚠️ Warning: Make sure the battery is at least at least charged before resetting 50-60%. Interrupting the formatting process due to battery discharge can damage the system partition and inability to boot the phone.
Prevention and optimization of storage
To keep the memory overflow problem from returning anytime soon, you need to change your smartphone usage habits: Regular prevention takes a couple of minutes a week, but saves hours of troubleshooting in the future. Try not to store files on your device that can be easily moved to the cloud.
Set up automatic sync with Google Photos or Mi Cloud with the “Free Space” option, which allows you to store originals online, leave only compressed copies on your phone or delete them after download, and it is also useful to periodically check the list of installed applications and delete those that you have not used for more than a month.
The table below compares cleaning methods and their effectiveness for different types of garbage:
| Cleaning method | Efficiency | Security of data | Difficulty |
|---|---|---|---|
| Built-in cleaner | Low/Mediocre | Safe. | Low. |
| Cleaning up the app cache | Medium | Safe (without data resetting) | Medium |
| Analysis through PC | Tall. | It requires caution. | Tall. |
| Full reset (Hard Reset) | Maximum | Complete deletion of data | Medium |
Following these simple rules will help keep your Xiaomi Redmi 4A in great shape. Remember that free space is necessary for temporary operations and normal operation of virtual memory.
💡
Regularly cleaning the cache of messengers and browsers prevents 80% of overflow problems of the category “Other” on smartphones with a small amount of memory.
