How to delete SMS in the smartphone Xiaomi Redmi 4: the complete guide

Owners of Xiaomi’s popular smartphones, particularly the Redmi 4, often face the need to free up internal memory or simply clean up correspondence. Despite the fact that modern instant messengers have almost completely replaced standard text messages, SMS messages still take up space in the device’s storage. Deleting unnecessary dialogue is not only a way to visually clean the contact list, but also an important measure to optimize the performance of the MIUI system.

Redmi devices’ data erasure procedures vary depending on the firmware version and shell used. In this article, we will look at all possible ways to delete messages, from standard methods to working with system files. Remote SMS on Redmi 4 without first synchronizing with Mi Cloud, you can’t restore the system’s standard tools. This is a critical nuance to consider before starting any operations with phone memory.

Next, we'll look at step-by-step algorithms that will help you manage incoming correspondence safely and efficiently, learn how to delete individual messages, entire dialogues, and also understand how to clean hidden folders where the system can send spam. Understanding the storage structure in Android will allow you to more competently approach the maintenance of your gadget.

Basic methods of deleting messages in a standard application

The easiest and most obvious method is to use the built-in functionality of the Messages app. The MIUI interface is quite intuitive, but the location of the controls may vary slightly from firmware version to version. To start, open the standard application, which usually has an envelope icon on your desktop or in the Tools folder.

To delete a single message inside the dialog, you need to open the correspondence you want, find the specific text you want to erase, and press it for a long time (about 1-2 seconds), then the message will be highlighted, and at the top of the screen will appear the toolbar, Here you need to find the basket icon or the "Delete" button. Confirm the action, and the message will disappear from the story.

If your goal is to delete the entire dialog, the algorithm will be different. If you're in the shared list of all correspondence, find a contact or number that needs to be cleared. Make a long-term click on the line with the contact name. In the menu that opens, select Delete or click on the appropriate cart icon. The system will request confirmation, because this action irreversibly deletes the entire history of correspondence with this subscriber.

• 🗑️ Single Deletion: Long-Tap on a Single Message Inside a Chat.
• 📂 Mass removal: selecting multiple messages by ticking through the control menu.
• 🚫 Deleting the dialog: Long-click on the contact bar in the shared list.
• ✅ Confirmation: A mandatory step to prevent accidental data loss.

⚠️ Note: When you delete a dialogue through the standard menu, messages are not in the shopping cart, but are permanently erased.

It's important to note that the standard MIUI app allows you to select messages in groups, and after a long time clicking on the first message, you can tap other messages in the same dialog, creating a random sample, which is convenient if you want to delete only part of the story, leaving, for example, the last codes received or addresses.

Working with a blocking list and spam

One feature of MIUI shell that is often underrated is the built-in antivirus and spam filter. All blocked numbers and messages marked as advertising by the system can accumulate in a separate storage. They don't show up in the shared list, but take up space and can interfere if there are too many of them.

To access this section, you need to open the Security app (green zipper icon). Select "Antispam" or "Block" from the menu. Here you will see tabs for calls and SMS messages. Going to the message section, you can see a list of all blocked inboxes. To delete them, use the "Clear" button or select specific records and delete them.

Xiaomi’s system filter can automatically detect emails, and if you notice that these messages are not deleted by yourself, check your filtering settings, and you may want to change your protection level or blacklist certain keywords so that the system will ignore them in the future.

Clearing the lock list is an important step in maintaining your phone, especially if you are actively using various delivery services or online stores that often send advertising SMS. Regularly checking this section will help clean the system.

Use of third-party applications for SMS management

The standard Android and MIUI tools are good, but third-party developers offer more flexible messaging tools. Google Play apps like Textra SMS, Pulse SMS or QKSMS can completely replace the standard app. They often have a more user-friendly interface for mass removal and sorting.

Installing a third-party messenger requires permissions to read and send SMS. Once you install and configure the application by default, you will get access to advanced features such as message scheduler, theme and, importantly for our theme, smart cleaning. Some applications allow you to delete messages older than a certain date or delete dialogs that do not have new messages for more than a month.

However, be careful when choosing such software: Third-party applications can have access to your personal correspondence, including two-factor authentication codes, and it is recommended to choose only proven programs with high ratings and a large number of users.

• 📱 Textra SMS: Easy and fast client with flexible removal settings.
• 💬 Pulse SMS: PC synchronization and advanced management tools.
• 🧹 SMS Organizer: automatic sorting and spam cleaning (relevant for some regions).
• 🛡️ Security: Check the permissions requested before installation.

⚠️ Note: When you delete the standard Messages app (if your version is available) MIUI If you can do this, or if you install a new messenger, the history of old SMS may not be transferred automatically.

Using alternative clients is especially relevant for Redmi 4, which, being a device of the past, can work slower with standard heavy applications.

Cleaning up cache and system debris messages

Even after deleting all visible messages, temporary files, thumbnails of media attachments and app cache can remain in the system. On Redmi 4, with its limited internal memory, this is especially true. Clearing the cache will not delete the text of the messages themselves (if you have already erased them), but will free up space occupied by service data.

To do this, go to Settings → Apps → All Apps. Find Messages (or your messenger name) in the list. Select Memory or Storage. Here you will see two buttons: Clear Cache and Clear Everything. Click Clear Cache securely and only delete temporary files.

The Clean All button (or Reset) will return the application to its state immediately after installation, meaning that all settings, drafts, and possibly the messaging database will be removed, and only use this method if the application is not working properly or you want to reset it completely.

Regular cache cleaning is a good habit for Xiaomi smartphone owners, which helps to avoid errors in the application and speeds up its launch. Redmi 4 recommends this procedure every 1-2 months.

Recovery of deleted messages and backup

Accidentally deleting an important SMS is a bad situation. Xiaomi smartphones with MIUI shell have a synchronization mechanism with the Mi Cloud service. If you have SMS synchronization enabled, you can restore deleted messages. Go to Settings → Mi Account → Mi Cloud and check the Messages section.

Recovery from the cloud is only possible if you have previously activated this feature. If sync has been turned off, you can't restore messages through standard means of the system. In such cases, users often turn to specialized computer software that tries to read data directly from the phone's memory, but the success of such operations on modern versions of Android is extremely low without root rights.

To avoid future data loss, set up automatic backups. Redmi 4 allows you to create local backups or use cloud services. Regularly creating copies of important data is the only guarantee of its safety.

System limitations and technical nuances of Redmi 4

The Redmi 4 is based on Snapdragon processors and runs different versions of Android (from 5.1 to 7.0 depending on the Prime/Pro modification). The message storage architecture on these versions of Android uses the SQLite database. This means that deleting a record is marking the space as free, but physically data can remain on the media until it is overwritten with new information.

But for the average user, this is not practical without the hardware, and it's important to understand that overflowing your SMS database can cause an app to crash or your phone to freeze when you try to open a dialogue. If your device starts to behave strangely when you're messaging, cleaning up your history is the first step in diagnosis.

It is also worth mentioning the double SIM-Redmi 4 has hardware to support two SIMs. When you delete messages, you can see the indicators. SIM 1 and SIM 2.Delete the dialog clears the history for both numbers, as they are combined into a single conversation thread with a contact, unless the SIM-card separation function was used in the display settings.

• 📉 Performance: Large amounts of SMS can slow down an old device.
• 💾 Database: SMS is stored in a system file that is restricted to.
• 🔄 Sync: Works independently for each SIM card in your Mi Account.
• ⚙️ Firmware: The interface may differ on the Global and China versions MIUI.

⚠️ Warning: Do not attempt to delete system message files through root-righted file managers unless you are sure of your actions. Damage to the mmsms.db file can cause the Messages app to stop running or the phone to go into a cyclical reboot.

Understanding these technical details will help you better manage your Xiaomi device. Redmi 4 is a reliable device, but it requires competent maintenance, especially in terms of memory management, to keep the speed up even after years of use.
