Owners of Samsung Galaxy smartphones often encounter sudden system locks due to full memory, when a red warning prevents you from taking a photo or updating an application, and standard cleaning of the gallery and deleting known apps do not free up hidden gigabytes.
The problem of “invisible” storage filling on devices Android is often hidden not in your personal files, but in system junk, update cache and hidden messenger folders. Standard application removal methods are often powerless against shadow copies of data that accumulate over months. In this material, we will analyze the deep mechanisms of clearing memory on smartphones Samsungusing both built-in tools and advanced methods of accessing the file system.
Ignoring a full storage can lead to a critical slowdown of the interface and even crashes in the operating system. Before moving on to radical measures like resetting settings, it is necessary to conduct a detailed diagnosis of the occupied space. We will look at a step-by-step algorithm of actions that will help restore your device's performance without losing important contacts and photos.
Diagnostics of occupied space using built-in tools
The first step should always be a deep analysis of what exactly is taking up space. In the shell One UI from Samsung a fairly informative statistical tool has been implemented, which is often overlooked. It allows you to visualize the distribution of data by category, separating system files from user content.
To start the analysis, you need to go to the menu Settings → Device maintenance → Memory. Here the system will scan and issue a detailed report. Pay attention to the “Other” or “System Files” category - this is where gigabytes of temporary data are often hidden that are not displayed in the standard file manager. If this category takes up more than 10-15 GB, manual intervention is required.
Sometimes the built-in analyzer may show incorrect data due to indexing errors. In this case, it makes sense to reboot the device in safe mode and run the scan again. This will eliminate the influence of third-party applications that may block access to their cache files while running in the background.
Clearing the cache and temporary application files
The most obvious, but often superficially performed step is clearing the cache. Many users delete only browser data, forgetting that social networks and instant messengers generate huge volumes of temporary files. Applications like Telegram or Viber save every photo and video you view to local storage, even if you have already deleted them from the chat.
To effectively clear the cache of a specific application, go to Settings → Applications, select the desired service and click on the "Storage" item. Here it is important to distinguish between the “Clear cache” and “Clear data” buttons. The first deletes temporary files without losing settings, while the second resets the application to its factory state, deleting logins and correspondence.
- 🗑️ Telegram: Go to the settings of the application itself, section “Data and memory” → “Memory usage”. Use the built-in cache clearing function with the ability to auto-delete.
- 📸 Instagram: In the application settings, find the “Media file cache” item and clear it. This will delete your saved previews, but will not affect your posts.
- 🌐 Chrome: In your browser history, select "Delete browsing data" by checking "Images and other files stored in the cache."
There is also a system cache partition that is not accessible through the app menu. This is the so-called Wipe Cache Partition. It is accessed through the recovery menu (Recovery Mode). To log in, turn off the phone, then hold down the key combination (usually Volume up + Power or connecting to a PC via USB-C when holding down the buttons for new models Samsung). Select item Wipe cache partition in the menu and confirm the action. This is safe and will not delete your personal files.
⚠️ Attention: In the recovery menu (Recovery), be extremely careful. Selecting the item
Wipe data/factory resetwill lead to the complete deletion of all data from the phone, including photos and contacts. Select only options containing the word "cache".
After clearing the Partition cache, the device may boot a little longer than usual when you turn it on for the first time - this is normal, the system is rebuilding application optimization.
Managing hidden folders of instant messengers and social networks
The main memory hog on modern smartphones is not the applications themselves, but the media files that they download automatically. The folder structure on Android is such that files from WhatsApp, Viber or TikTok are often duplicated or saved in hidden directories that are not visible in the regular gallery.
For manual deletion, you must use a file manager with access to system folders, for example, the built-in "My Files" from Samsung or third-party Solid Explorer. Go to the root directory and find the folder Android → media. This is where modern versions Android 11/12/13/14 store application data. Inside you will find folders with package names, for example com.whatsapp or com.viber.voip.
| Application | Folder path (example) | What can be deleted | Risk of data loss |
|---|---|---|---|
Android/media/com.whatsapp/WhatsApp/Media |
Folders Sent, Wallpaper, old videos |
Low (if there is a backup) | |
| Telegram | Android/media/org.telegram.messenger |
Folder Telegram Images/Video |
Low (files are in the cloud) |
| Viber | Android/media/com.viber.voip |
Folder Viber Media |
Medium (check important photos) |
| TikTok | Android/media/com.zhiliaoapp.musically |
Folder Download (drafts and cache) |
High (deleting drafts) |
When manually deleting files From these directories, it is important not to touch database files with the extension .db or .sqlite, since they contain the history of correspondence. Delete only media content: images (.jpg, .png), videos (.mp4) and audio files. Regularly cleaning out these folders can free up up to 5-10 GB of space monthly for active users.
Why is the Android/media folder protected?
Starting with Android 11, Google has restricted access to this folder to improve security. Some file managers may not show its contents without granting special permissions through the system window.
Analysis of large files and duplicates
Often the memory is filled with single, but very large files, the existence of which you forgot. These could be downloaded movies, forgotten voice recorders after long lectures, or game backups. Searching for such “heavyweights” manually takes hours, so it is advisable to use specialized disk analysis utilities.
Applications like DiskUsage or Storage Analyzer build a visual memory map, where the size of the rectangle corresponds to the file size. This allows you to instantly identify anomalies: for example, a forgotten folder with system logs of 2 GB in size or a series of unsuccessful video recordings. Samsung also has a built-in duplicate search function in the “Gallery” application.
Go to “Gallery” → menu (three bars) → “Tools” → “Storage Management”. The system will offer to delete blurry pictures, similar photos and large video files. The algorithms One UI are smart enough not to confuse a series of similar frames with important documents, but always review the selection before bulk deleting.

☑️ Storage audit
Setting up an SD card and transferring data
If the internal memory of the device is physically limited (for example, 64 or 128 GB), the only radical solution is to expand the storage. Smartphones Samsung series A i S (with the exception of some ultra-flagships of recent years) support format memory cards microSD.
After installing the card, it is important to configure it correctly. In the Settings → Device maintenance → Memory menu, select a card and click “Storage Settings”. You can use it as "Portable storage" (for photos and music) or, in rare cases on older models, as internal memory. The first option is preferable for compatibility.
To automatically free up space, set the camera to save photos and videos directly to the memory card. Go to the Camera app → settings (gear) → Storage → select SD card. This will prevent the internal storage from filling up with heavy video files in the future.
Path to check the card status:
Settings → Device maintenance → Storage → Memory card
Also consider moving some applications to the card. Although modern versions Android limit this functionality, some apps still allow movement. Go to the application settings and check if the “Edit” button in the “Storage” section is active. If it is gray, the developer does not provide for transfer.
Using an SD card as the main place for media content is the only way to forget forever about the problem of lack of memory on budget smartphones.
Radical measures and resetting settings
If none of the above methods helped free up the critical amount of memory, and the system continues to work unstable, the file system may be damaged or fatal errors have accumulated in it. In this case, the only effective solution is a full reset to factory settings.
Before this procedure, be sure to create a backup copy of all important data through your account Samsung Cloud or Google Drive. Resetting will delete absolutely everything: applications, settings, photos, contacts (if they are not synchronized). This action will return the phone to its “out of the box” state, guaranteed to clear all hidden sections of the system.
To perform a reset, go to Settings → General settings → Reset → Reset data. Confirm the action and wait for the reboot. The process may take from 10 to 30 minutes depending on the amount of previously saved information and the speed of the device's flash memory.
⚠️ Attention: Make sure the battery level is at least 50% before starting the reset. Interrupting the system recording process due to a low battery may cause the phone to stop turning on (“bricking”).
After the reset, do not rush to restore all applications at once from a backup copy. Try using a “clean” phone for a couple of days. It often turns out that you don’t actually need half of the installed apps, and this is the best moment for a digital detox.
Why is the memory not freed up after deleting files?
Perhaps the files ended up in the “Trash” inside the “Gallery” or “My Files” application. Check these folders and clean them out permanently. Also, some applications may block the deletion of files while they are running in the background - try restarting the phone before checking.
Is it possible to delete the Android folder?
No, deleting the folder itself Android is absolutely not allowed. This will result in all applications not working and possible system crashes. You can only delete contents inside subfolders media and obbrelated to deleted games or cache.
How to clear the memory if the phone does not turn on?
If the phone is stuck on the screensaver due to memory full, try going into Recovery mode (like described in the section about the cache) and execute Wipe cache partition. If this does not help, you will need to connect to a PC and use official software Samsung Smart Switch or Odin for flashing.
Does full memory affect Internet speed?
Indirectly - yes. When the internal memory is critically low, the system has no place to create temporary buffers for processing network packets and caching web pages, which can cause slow loading of content and freezing of browsers.
