Deleting files on Android often seems irreversible - especially when it comes to photos, work documents or archives. However, the operating system and many applications leave “traces” of deleted data that can be recovered within a limited time. Main rule: the sooner you take action, the higher the chances of success. In this article, we will analyze all the available methods - from built-in tools to professional utilities, and also explain why some methods only work on rootdevices.

Standard Android mechanisms do not always offer obvious solutions. For example, many users do not know that Google Photos stores deleted pictures in the “trash” until 60 days, and some files can even be retrieved from the messenger cache. But there are also pitfalls: recovery through ADB or specialized apps like DiskDigger requires technical skills and can damage data if used incorrectly.

If you deleted files less than 24 hours ago, start with the simple methods (sections 2–3). For complex cases - when the data was erased a long time ago or after a factory reset - advanced tools will be required (sections 5-6). At the end of the article you will find FAQ answers to common questions and tips on how to avoid data loss in the future.

1. Check the "Trash" in standard Android applications

Many built-in and third-party applications on Android have their own "trash" (Trash or Recycle Bin), where files are stored temporarily before being permanently deleted. This is the first step that is worth checking - it does not require additional apps and works even without the Internet.

For example, in Google Photos deleted images remain in the trash 60 days (or less if you manually emptied it). To restore: Google Photos data-i="61">Trash

  1. Open the application Google Photos.
  2. Tap on the profile icon in the upper right corner → Basket.
  3. Select the files you need, click Restore.

Similar baskets are available in:

  • 📁 Gallery Samsung (up to 15 days of storage).
  • 📄 Google Drive (30 days for free accounts).
  • 🎵 Google Music (if you uploaded tracks to the cloud).
  • 📱 File manager MIUI (on smartphones Xiaomi).

Important: if you used the function Empty Recycle Bin or cloud synchronization was disabled, files could be permanently deleted. In this case, proceed to the following methods.

💡

If you regularly lose files, turn on automatic synchronization in Google Photos or Google Drive. To do this, go to Settings → Backup and synchronization and activate the option.

2. Recovery via cloud services

Cloud storage is a reliable way to return files if they were uploaded there before deletion. Even if you don't remember whether you turned on backup, check the following services:

Google Drive automatically saves some types of files (for example, documents Google Docs or spreadsheets Sheets). To restore: Google Drive →

  1. Open drive.google.com in the browser.
  2. From the left menu select Basket.
  3. Find the file, right-click → Recover.

For other cloud services:

  • 🌥️ Dropbox: go to Deleted files (up to 30 days of storage for free accounts).
  • ☁️ OneDrive: open Cart in the web version or application (storage up to 93 days).
  • 📱 Samsung Cloud: available only on devices Samsung with an account Samsung Account.

If the files are not found in the cloud basket, check file versions. For example, in Google Drive you can restore the previous version of a document:

  1. Open the file in Google Drive.
  2. Click File → Versions.
  3. Select the desired version and click Restore.
What to do if the cloud has not synchronized?

If the file was not uploaded to the cloud before deleting, check your synchronization settings. For example, in Google Photos go to Settings → Backup and synchronization. If the option has been disabled, the cloud will not be able to help.

3. Using a file manager with a recovery function

Some files, after deletion, remain in the device’s memory until their place is overwritten by new data. Specialized file managers can scan internal memory and SD card for the presence of such “residues”.

One ​​of the most effective applications is DiskDigger (there are free and paid versions). It works without rootrights, but with them the chances of recovery are higher. Instructions:

  1. Download DiskDigger from Google Play.
  2. Select the type of files to search (photos, videos, documents).
  3. Run Basic scan (without root) or Full scan (with root).
  4. Once completed, select the files and click Recover.

Alternative apps:

  • 🔍 Dumpster —works as a recycle bin for all files (must be installed in advance).
  • 📂 Recuva (requires connecting Android to the PC via USB debugging).
  • 🛠️ EaseUS MobiSaver —paid solution with a high recovery rate.

Important: do not install recovery apps on the same memory partition where the deleted files were located. This will reduce the chances of success, since new data may overwrite old ones.

4. Recovery via ADB (for advanced users)

Android Debug Bridge (ADB) is a tool for low-level access to the device’s file system. It allows you to scan memory for deleted files, but requires enabled USB debugging and basic knowledge of the command line.

Instructions for Windows:

  1. Download ADB Tools and unzip to a folder.
  2. Enable Developer mode on your phone: go to Settings → About phone → Build number (tap 7 times).
  3. Activate USB debugging in Settings → System → For developers.
  4. Connect the phone to the PC and run in command line: 
    adb devices

    (your device should be displayed).

  5. Use the command to search for deleted files (example for photos): 
    adb shell "find /storage/emulated/0/ -type f -name '.jpg' -o -name '.png'"

Method limitations:

  • ⚠️ Without root-right ADB will not see system partitions.
  • ⚠️ Recovered files may be damaged.
  • ⚠️ Does not work on devices with encrypted memory (for example, Samsung Knox).

If ADB did not find the files, try Fastboot (for devices with an unlocked bootloader), but this is risky and can lead to briku phone failure.

💡

ADB is only suitable for users with technical skills. If you are not sure of the commands, use specialized apps like DiskDigger or contact a specialist.

5. Restoring after a factory reset or system damage

If files were deleted after hard reset (factory reset) or due to a firmware failure, standard methods will not help. In this case, you will need:

  • 🔧 Firmware with data saving (if the phone does not turn on, but the memory is not damaged).
  • 💾 Reading memory via Chip-Off (requires soldering equipment and skills).
  • 🖥️ Use JTAGinterface (for devices with support).

These methods are complex and risky. For example, Chip-Off involves physically removing the memory chip and reading data through the programmer. The cost of such a service in service centers starts from 5,000 rubles, but there is no guarantee of recovery.

If you decide to act independently:

  1. Download the firmware for your phone model (for example, from the website XDA Developers).
  2. Use SP Flash Tool (for Mediatek) or Odin (for Samsung) for flashing without formatting user data.
  3. After restoring the system, try apps like DiskDigger or PhotoRec.
⚠️ Attention: Unprofessional firmware can permanently damage the data. Encryption), recovery without an encryption key is impossible. FBE (File-Based Encryption) or FDE (Full-Disk Encryption), recovery without an encryption key is impossible.

6. Preventing data loss: how to avoid problems in the future

The best way to avoid losing files is to set up backups in advance and use reliable tools. Here are proven methods:

Automatic backup:

  • ☁️ Set Google Photos to automatic upload (in Settings → Backup and synchronization).
  • 📱 Enable Android backup in Settings → Google → Backup (saves application data, contacts, SMS).
  • 💾 Use Titanium Backup (requires root) to create full backups.

Manual copies:

  • 🖥️ Regularly connect your phone to your PC and copy important files to your hard drive.
  • 📁 Use SD card to store backups (but remember that it can also fail).

Protection against accidental deletion:

  • 🗑️ Install Dumpster or a similar recycle bin application.
  • 🔒 Set up confirmation before deleting in the file manager.
Backup method Pros Cons Cost
Google Photos Automatic synchronization, 15 GB free Photo compression in the free plan Free (up to 15 GB)
Google Drive Storage of any files, integration with Android Volume limitation (15 GB per account) Free (up to 15 GB)
Titanium Backup Full backup of applications and data Requires root, complex interface ~300 RUR (premium)
Local copy to PC No volume restrictions, full control Manual process, risk of loss if PC breaks Free
SD card Portable media, does not depend on the cloud Risk of physical damage, limited service life From 500 rub. (for 32 GB)
⚠️ Attention: Even with backups, don't put all your eggs in one basket. For example, if you only use Google Photos, but forgot your account password, access to the files will be lost. Combine cloud + local storage.

FAQ: Frequently asked questions about recovering files on Android

Is it possible to recover files after completely formatting the phone?

If it was completed full formatting (for example, through fastboot or at a service center), the chances are extremely low. Data at the file system level is erased, and their recovery is only possible using Chip-Off or JTAG, which is expensive and does not guarantee results.

Exception: if formatting was fast (for example, through Settings → Reset), some of the data may remain. In this case, it will help DiskDigger or PhotoRec.

How to recover deleted messages in WhatsApp?

WhatsApp stores backup copies of chats in Google Drive (if the setting is enabled) or locally on the phone. To restore: Google Drive data-i="275">(path:

  1. Uninstall and reinstall WhatsApp.
  2. When you first launch the application, you will be prompted to restore chats from backup.
  3. If the local backup is damaged, check Google Drive (path: /sdcard/WhatsApp/Databases).

Important: backups are created only when connected to Wi-Fi and if there is enough space on the phone.

Will recovery apps help if the phone does not turn on?

If the device does not respond to charging or is stuck on the logo, apps seem DiskDigger useless. In this case:

  • Try to boot into Recovery Mode (usually Power + Volume Up) and reset.
  • If the phone is detected by the PC as Qualcomm 9008 or Mediatek Preloader, you can try flash it through SP Flash Tool or QFil.
  • If there is physical damage (fall, water), contact a service center with equipment for Chip-Off.
How much does it cost to restore data at a service center?

The cost depends on the complexity:

  • Logical recovery (through apps): 1,500–3,000 rub.
  • Chip-Off (chip removal): 5,000–15,000 rub.
  • JTAG (for devices with damaged firmware): 3 000–10,000 rub.

Prices are valid for Moscow and St. Petersburg. In regions they may differ by 20–30%.

Is it possible to recover files from a damaged SD card?

If SD card is not readable, but is detected by the system, try:

  1. Connect it to the PC via a card reader.
  2. Use PhotoRec or TestDisk to scan.
  3. If the card is not detected, try apps like Recuva in deep mode scanning.

If the card is physically damaged (for example, a broken contact), restoration is only possible in the laboratory.
