Samsung Galaxy A01 is a budget smartphone with 16 or 32 GB of internal memory, which tends to run out at the most inopportune moment. Even if you don’t install games or download movies, the system, updates and application cache gradually eat up free space. In this article we will look all working methods of clearing memory on Galaxy A01, from basic to radical, and also explain why some methods may not work.

It is important to understand: Android 10 (used v A01) has memory management features that differ from new versions. For example, there is no built-in “memory analyzer”, as in Android 12+, and some system files take up more space due to optimization for weak hardware. But this does not mean that it is impossible to free up space - you just need to act systematically.

1. Analysis of occupied space: what exactly is “eating” memory?

Before cleaning, figure it out what data takes up the most space. On Galaxy A01 there are built-in tools for this:

  1. Settings → Device care → Memory. Here is a diagram showing the distribution of memory by category: Applications, Images, Video, Audio and System data.
  2. File manager My Files (folder icon on the main screen). Open the section Memory analysis —large files and folders are shown here, sorted by size.

Typical memory “eaters” on A01:

  • 📸 Photo and video in high resolution (especially if the camera is configured to shoot in high resolution) data-i="58">Photos and videos 12 MP data-i="64">: APK files, documents, archives that were downloaded “just in case.” 12 MP).
  • 🎮 Cash games (For example, Free Fire or PUBG Mobile can take up to 2–3 GB).
  • 📥 Downloads: APK files, documents, archives that were downloaded “just in case.”
  • 🤖 System cache and updates Android (sometimes take up to 1 GB in the folder /cache).
  • 📱 Duplicate filescreated by instant messengers (WhatsApp, Telegram) or gallery.

If the section System data is occupied by more than 5 GB, this is a cause for concern. The system may be clogged with temporary files or damaged updates. In this case, it will help clearing the cache manually (more on this in the next section).

2. Clearing the application cache: a quick way to free up 1-3 GB

Caches are temporary files that applications create to speed up their work. Over time, they accumulate and can. occupy gigabytes. Galaxy A01 the cache can be cleared in two ways:

Method 1: Clearing the cache for individual applications

  1. Open Settings → Applications.
  2. Select an application (for example, Chrome or Facebook).
  3. Click Memory → Clear cache.

Method 2: Mass clear cache (for all applications)

  1. Go to Settings → Device care → Memory.
  2. Click Clear in the section Unnecessary data.
  3. Confirm the action - system will delete the cache of all applications except system ones.

Important! Clearing the cache does not delete your data (logins, game saves), but some applications may run slower the next time you launch them until the cache is restored.

Close all background applications

Connect to Wi-Fi (if you plan to update applications after cleaning)

Check free space in the "Memory" section

Make a backup copy of important data (in case of failure)

-->

If after clearing the cache free space does not appear, check the folder /Android/data — sometimes “dead” files from deleted applications remain there. To do this:

  1. Open My Files → Internal storage.
  2. Go to the folder Android → data.
  3. Delete folders with the names of applications that you deleted long ago. (for example com.tencent.ig for PUBG Mobileif the game has already been uninstalled).
💡

After mass clearing the cache, reboot the phone - this will help the system correctly recalculate the free space.

3. Removing unnecessary applications and their remnants

There are many system applications preinstalled Galaxy A01 many system applications are preinstalled Samsung and Googlethat cannot be removed using standard means. However, third party apps and games often take up the lion's share of memory. Here's how to deal with them:

How to find and remove “heavy” applications

  1. Open Settings → Applications.
  2. Click on the three dots in the upper right corner → Sort by size.
  3. View the list: applications weighing 500 MB and above are the main candidates for removal.

Typical “culprits”:

  • 🎮 Games: Free Fire (1.5 GB+), Call of Duty Mobile (2 GB+), Genshin Impact (4 GB+).
  • 📺 Social networks: Facebook (300–500 MB), TikTok (200–400 MB).
  • 📱 Messengers: Telegram (cache can grow up to 1 GB), WhatsApp (saved media files).
  • 🔍 Launchers and widgets (for example, Nova Launcher or GO Launcher).

How to remove remnants of applications after uninstallation

Even after deleting an application, its files may remain in the folders /Android/obb and /Android/data. To clear them:

  1. Open My Files → Internal storage → Android.
  2. Go to folders obb i data.
  3. Delete folders with the names of deleted applications (for example, com.miHoYo.GenshinImpact).
What to do if the application is not uninstalled?

If the "Delete" button is inactive, then the application is a system one. In this case, you can:

1. Disable it (in the application settings, click "Disable").

2. updates (the "Uninstall updates" button) to return the factory version.

3. Use ADB commands for uninstallation (requires a PC and USB debugging).

Warning: Do not delete system applications Samsung (for example, Samsung Health or Knox) without understanding the consequences - this can lead to malfunctions of the phone.

4. Multimedia optimization: photos, videos and music

High-resolution photos and videos are the main ones. "memory eaters". By default, the camera shoots in Galaxy A01 The camera shoots in 12 MP, and video in Full HD, which quickly fills up the storage. Here's how to deal with this:

Method 1: Reducing camera resolution

  1. Open the application Camera.
  2. Click on the gear (⚙️) → Photo resolution.
  3. Select 9 MP or 5 MP instead of 12 MP.
  4. For video, install HD (720p) instead Full HD (1080p).

Method 2: Transfer photos and videos to a memory card or cloud

If you have microSD card (up to 512 GB), transfer multimedia to it:

  1. Open My Files → Internal storage → DCIM → Camera.
  2. Select files → click Move → select SD card.

For cloud storage the following are suitable:

  • 🌥️ Google Photos (free 15 GB, photo compression up to 16 MP).
  • 🌥️ Yandex Disk (10 GB free).
  • 🌥️ Samsung Cloud (5 GB free for owners Samsung).

Attention! When using cloud services disable automatic downloading of originals in high resolution this will quickly exhaust the free space. In Google Photos select setting High quality (compression) instead Original quality.

Method 3: Removing duplicates and unnecessary files

Applications like Files by Google or CCleaner can find:

  • 📸 Duplicate photos (for example, screenshots with the same content).
  • 🎥 Failed videos (blurry or interrupted recordings).
  • 📄 Old documents and APK files in the folder Downloads.
💡

Transferring photos to a memory card or to the cloud is the most effective way to free up space if you are not willing to sacrifice quality snapshots.

5. Cleaning downloads and temporary files

Folder Downloads (Download) is a “black hole” for memory. The following accumulate here:

  • 📄 PDF files that you opened once.
  • 📦 Archives (ZIP, RAR) that have already been unpacked.
  • 🎵 Music and ringtones, downloaded “for testing”.
  • 📱 APK files of applications installed manually.

How to clear:

  1. Open My Files → Internal storage → Downloads.
  2. Sort files by Modified date or Size.
  3. Delete everything that is older than 3 months or weighs more than 50 MB.

Also check the folders:

  • 📂 /Android/obb — additional game files are stored here (can be deleted if the game is deleted).
  • 📂 /Android/data — cache and application data.
  • 📂 /DCIM/.thumbnails — photo and video thumbnails (can be safely cleared).

Attention! Do not delete files in folders /system, /efs or /dev —this may lead to phone breakdown and loss of warranty.

6. Resetting to factory settings: a radical method

If all the previous methods did not help, and the phone still shows “Memory full”, remains full reset (hard reset). This will delete all dataincluding:

  • 📱 Applications and their settings.
  • 📸 Photos, videos, music (if they are not on SD card).
  • 📞 Contacts, SMS, call log (if not synchronized with Google).
  • 🎮 Game saves (if not linked to an account).

How to reset:

  1. Create a backup copy of important data (contacts, photos, documents).
  2. Go to Settings → General settings → Reset → Reset data.
  3. Enter the PIN code or pattern.
  4. Click Delete everything and wait until the reboot.

After reset:

  • 🔄 Do not restore the backup completely - select only the data you need (for example, contacts).
  • 📱 Do not install everything old applications immediately - add them as needed.
  • 🔧 Disable automatic application updates in Google Play.
What should I do if, after a reset, the memory quickly runs out again?

This means that the problem is in system files or damaged firmware. In this case, it will help:

1. Software update via Settings → Software update.

2. via Odin (requires a PC and knowledge of the process).

3. Contacting a service center Samsung (if the phone is under warranty).

Attention! On Galaxy A01 resetting to factory settings may take up to 10-15 minutes. Do not interrupt the process and do not remove the battery —this will lead to serious failures.

7. Prevention: how to avoid filling up the memory in the future

To avoid running out of memory too quickly, follow these rules: Galaxy A01 don't end too quickly, follow these rules:

Problem Solution Saving memory
Application cache grows Clear the cache once a month through Settings → Memory Up to 1–2 GB
Photos and videos take up a lot of space Reduce camera resolution up to 9 MP and transfer files to an SD card Up to 3–5 GB per year
Applications update automatically Disable auto-update in Google Play (Settings → Auto-update applications → Never) Up to 500 MB per month
Messengers save media files In WhatsApp i Telegram turn off automatic photo/video downloading Up to 1 GB per month
System updates take up space Remove old updates via Settings → Memory → System data Up to 500 MB

Also useful:

  • 📱 Use light versions of applications (for example, Facebook Lite, Messenger Lite).
  • 🔄 Check the folder regularly Downloads and clean it.
  • 🛡️ Install an antivirus (for example, Malwarebytes) to search for malicious files that can clog your memory.
💡

If you often shoot video, set the camera to record in the format HEVC (H.265) —it takes up 30-40% less space with the same quality.
