How to increase memory Xiaomi Redmi 7A

Owners of the popular budget smartphone Xiaomi Redmi 7A often face a lack of free space in the drive. the Basic version of the device is equipped with only 32 gigabytes of internal memory, of which the system partition MIUI occupies a significant part, leaving the user only about 15-18 GB. This becomes a critical obstacle when installing modern heavy applications and saving a lot of media.

The problem can be solved by software methods or by physically installing a microSD card. It is important to understand that physically increasing the volume of the built-in NAND chip is impossible without soldering, but competent file system management allows you to effectively expand the available space. Below we will look at proven algorithms of actions that will help to unload the device.

Analysis of the current state of the storage

The first step before any manipulation is to make a detailed diagnosis of what exactly is taking up precious space. Android provides built-in tools for data visualization, but for deep analysis, it is better to use specialized utilities.

Users are often surprised to find that the system partition is bloated by messenger cache and junk update files. The built-in analyzer will show the main categories: applications, images, video, audio, etc. App cache can take up gigabytes if it is not regularly cleaned.

• 📱 Apps and games often take up to 60% of the space, especially if they are social media.
• 📸 Gallery and media files – high-resolution photos and videos quickly eat free megabytes.
• 🗑️ Recycle Bin and deleted files - in the shell MIUI Deleted photos can be stored for 30 days, taking up space.

Use the built-in Cleanup feature in the Security app, which allows you to quickly delete temporary files, but does not always cope with deep residual files of remote programs. For more accurate control, it is recommended to periodically check the Download and Bluetooth folder, where forgotten APK installers accumulate.

⚠️ Before deleting system files or clearing folders with unknown content, make sure they are not required for the operating system to work, otherwise Xiaomi Redmi 7A may work unstablely.

Use of microSD memory card

The most efficient and safest way to add space is to install a microSD card. The Redmi 7A supports cards up to 256 GB (officially) and often works successfully with 512 GB. This allows you to transfer all heavy media files to an external medium.

After installing the card in a slot that is combined with a tray for the second SIM-So if you format the card, the system will ask you to format the drive, and you want to choose the right formatting type, and if you format the card as "Adoptable Storage," it will become part of the system partition, but on Redmi. 7A This feature is often hidden or unstable due to low speed of writing budget cards.

You'd better use Portable Storage mode, where you can transfer photos, videos, music and documents to the map, and some apps allow you to select a way to save data by specifying a memory card, which frees up the built-in drive for the system to run and the active programs cache.

⚠️ Note: Do not remove the memory card while the phone is running or writing data.This can damage the file system and lose all information on the media without the possibility of recovery.

Transfer of applications to an external drive

The issue of porting apps to a memory card is one of the most challenging in the Android ecosystem, and since version 6.0, Google has limited this capability, and manufacturers like Xiaomi often hide it in their settings, but there are workarounds on the Redmi 7A with the MIUI shell.

The standard method is to go to the Settings menu. → Annexes → All applications. When you select the right program, see if the Move to button is active. SD-If it's gray or not, the app developer has banned the portability, which is typical of system services and many of today's heavy games.

There is a method of activating the default memory function through the engineer’s hidden menu, but it requires caution.

1. Open the Phone app and dial ##6485##.

2.In the menu that appears, find the item associated with the installation of the preferred installation location (MFQ).

3. Change the value to the default setting to SD-map.

Cache cleaning and garbage removal through ADB

For advanced users who want to free up space as much as possible without deleting the necessary data, the method of cleaning through debugging via USB is suitable. This requires connecting the smartphone to the computer and installing ADB drivers. This method allows you to remove the cache of system applications that is not available through the usual interface.

First, activate Developer Mode. Go to Settings → About Phone and quickly click on MIUI Version seven times. Then, in the advanced settings, turn on USB Debugging. Connect your phone to your PC and execute a command to clear the cache of a particular application or system.

adb shell pm trim-caches 999999999

This command will try to trim the cache of all applications to a minimum, and you can also use the command to delete temporary files:

adb shell rm -rf /data/local/tmp/*

Optimization of the work of messengers

Modern messaging apps like Telegram, WhatsApp and Viber are the main memory eaters. They store every photo and video they receive into a gallery, duplicating files into their internal cache. On Redmi 7A, with its modest volume, this becomes a critical factor.

In each messenger setting, you need to find the Data and Storage (or similar) section, and you need to turn off auto-save media to the gallery, which will not delete files from the application itself, but stop creating copies of them in the system folder of images, which often frees up several gigabytes.

• 🧹 In Telegram, use the built-in “Memory Use” function to clean the cache with autodelete settings.
• 💾 In WhatsApp, set up the backup frequency and eliminate the video from the backup in Google Drive.
• 🚫 Disable media preloads in groups and channels to save traffic and space.

It is critical to clean the Send folder regularly (once a week) in messengers, as it stores copies of all files you have ever sent to interlocutors.
