How to recover deleted files on Android if there is no computer at hand - every smartphone or tablet user asks the search engine when faced with accidentally erased data.
In case of loss of files on a PC, information is recovered quite easily using programs that scan a hard disk or flash drive. Usually, at least part of the information is restored in this way.
If the computer is unavailable for some reason, many consider Android data to be lost forever. This is not the case - accidentally deleted files can also be saved from a mobile device.
Recovery using a computer
Recall the easiest way to recover information on Android - using a computer and a system scan. In this case, we can assume that the hard drives of a smartphone or tablet are checked in the same way as a regular flash drive or USB drive.
In case of loss of data from the internal non-removable memory, you should:
- Using a special cable, which usually comes with the gadget, connect to a PC;
- Wait until the system automatically installs the necessary drivers (if this did not happen earlier, during previous connections to the computer);
- Select "Connect to USB storage" on your smartphone (tablet):
Choosing to connect a mobile device to a PC
- Download, install and run the appropriate file recovery software.
Recuva program
One of the best options for recovering your PC system is Recuva, a free program that works when you connect your smartphone to your computer.
You can download it on the official website: www.piriform.com/recuva.
It acts as follows:
- After starting, a window opens with the types of files that require recovery;
- By selecting the data that the program will search for during scanning, you can enable additional in-depth analysis. In this case, Recuva will recover more information, although it will require several hours of searching;
- After scanning is complete, a list of files to be restored appears on the PC screen. After making sure that it is possible to return the information you need (it will be marked in green), mark it and continue the program;
- Transfer the recovered files back to your mobile device.
7-Data Android Recovery Program
7-Data Android Recovery is a popular application that recovers lost and deleted files from smartphones and tablets. The purpose of the program is to work with Android OS devices.
In terms of its functionality, it resembles Recuva, but it can work with any kind of internal memory. This means that information can be restored not only from an external or internal storage device, but even from the device's RAM.
Recover Deleted Information with 7-Data Android Recovery
After installing the program, a scan of the gadget starts, after which you will have the same list of recoverable files. At the same time, the deleted photos can even be seen in the "preview" mode, returning only those of them that you really need.
After the end of the program, the data is returned to the device.
Recovering files on a mobile device
Sometimes the gadget is not able to connect, and the files need to be restored, or at least try to do it very urgently. In this case, it is worth downloading special applications that work from the phone.
True, some of them will need "superuser rights" or root access to start and restore - but you should know that this automatically removes the factory warranty from your smartphone or tablet.
Basket
A simple way to get back the deleted information on a smartphone is to use the "trash bin". Its principle of operation is similar to a similar program for a PC:
- The deleted data is placed in storage;
- If you need to restore the files, you can return them to the same place;
- After some time (user-specified), the information is deleted.
The program works without root and quite simply returns the files to their place. It is convenient to use it, however, if the data has already disappeared, it will not be returned by installing the "Recycle Bin".
To prevent the loss of information, you should download the Dumpster - Recycle Bin application in advance and run it on your smartphone (tablet).
Recycle Bin Program
After installing the program, any file that is in the "trash", but has not yet been deleted from it, can be restored by simply going into the application and selecting the necessary data. But after the removal, you will have to deal with the restoration using other methods.
GT Recovery
Another program that works on gadgets of any brands that install Android on their products (that is, on almost any smartphone except Apple and Nokia) is GT Recovery.
It is provided by the manufacturer for free, and you can find the application in the Google Play store.
With the help of the program, files of any type are restored - photos, videos or texts. Reviews about it indicate a high percentage of recovery, especially if a little time has passed after removal or loss.
Some drawbacks include the need for root access, however:
- If you have instructions for your gadget or a small free program, it is quite possible to get superuser rights (for example, for a Samsung, you should use the Odin application);
- There are versions for which root is not required (GT Recovery no Root)
GT Recovery no Root interface
Undeleter
Another reliable option for recovering files directly from your phone or tablet is the Undeleter app. It is downloaded from Google Play and comes in 2 versions: paid and free.
The free version allows you to recover deleted images, the paid version allows you to recover any data both from a flash card and from the internal memory. Recovery is easy to manage:
- After selecting the desired folder, a scan is performed and a list of files to be restored is displayed;
- Having selected the necessary data, they are restored to the same place where they were before the deletion.
How Undeleter works on Android
The disadvantage of the program is that it has root access for Undeleter to work. But you can install it, like the previous application, after the files have been deleted.
Titanium Backup
There is another way to solve the situation if the user has lost data and even deleted system files. To do this, download the free Titanium backup application.
It works in almost the same mode as the "Recycle Bin", but has more functionality, restoring:
- Photo and video;
- Programs (in 2 modes: only the files themselves, or a full return of all settings, including saving games);
- Contacts and SMS messages. True, to return the phone numbers to the smartphone, you will have to write them down to the memory card in advance.
List of Android apps in Titanium Backup
The recovery information is saved on the memory card in the TitaniumBackup folder.
Some of these "backups" can even be returned to a new phone - except for the operating system settings, as this can lead to software malfunctions.
When viewing the list of applications and files, it is indicated whether there is a backup copy for it or not.
With all the advantages of the program over the "Recycle Bin", it, like most other data recovery applications, requires the rights of the "superuser".
And when comparing with programs like GT Recovery and even with the return of information from a computer, it is worth noting the impossibility of getting back your files if Titanium backup is not installed on the device in advance.
In addition, system recovery files take up a lot of memory space.
Prophylaxis
Once you've got an idea of what to do if you accidentally deleted a file on your mobile device, you should prepare in advance for such situations.
That is, install an auxiliary program and, preferably, write several backup options to the memory card - after all, at the moment when you need the data, you may not have access not only to the computer, but also to the Internet.
And you should also take care of the safety of important information, from time to time transferring it to more reliable media (or at least to the same PC, from where it will be easier to return it).
It is also worth noting that for a more complete data recovery, regardless of how it will be done, you should avoid writing to the memory of your smartphone or tablet and to a flash card before you get the file you need back.
Advice: Sometimes it is even better to turn off Wi-Fi and GSM-module, due to which SMS messages or application updates can be installed on the device.
How to recover deleted files on Android
Recover deleted pictures, photos, and videos. Saving recovered files and the ability to send them to mail.
There are situations when rolling back a device to factory settings is the best solution to a problem that has arisen. You can perform a reset in several ways: through the reset device itself, or using a computer. ...
Why reset
Hard Reset - rolls back the operating system to the default values. Performing a reset removes all files and third-party applications from the device memory and returns all settings to the factory settings. By resetting the system, you will get a clean device, that is, it will be in the form in which it was in the store.
A reset can come in handy in the following situations:
- the device began to freeze due to a large number of installed programs;
- the system began to freeze due to overloaded memory;
- there are many files left in the file system from remote applications that take up free space;
- the device is being sold, so you need to delete all personal information from it;
- you need to reset the password as it was forgotten.
As a result, it turns out that the reset must be performed when it is necessary to format the device.
How to save data
Since a system reset erases all data (videos, photos, music, pictures, books and other items) from the device, it is strongly recommended that you think about how to save all important information in advance. The easiest way is to transfer all your important files to a memory card or computer. The reset does not delete the items stored on the SD card even if it is inserted into the device, but it is better to remove the memory card for the duration of the operation just in case.
Another way is to create a backup, which will store all the files. After performing a reset, you can restore the system from a previously created backup, and all items and applications will return. The positive side of this method is that you will not lose not only files, but also applications. The negative side - if the reset is carried out in order to clear the device of unused files, then when restoring from the backup, the files that you wanted to get rid of will also be restored.
Copying is carried out using the Google service and only via Wi-Fi, since the amount of information is too large to be downloaded via the mobile Internet. Go to device settings, open the "Restore and reset" tab and make sure that the automatic backup function is enabled. The copy will be linked to your Google account, and you can recover from it after you reset. The device itself will offer you to use the found copy.
Activating file backup

Through the recovery menu
If you have a turned off device, but there is no way to turn it on, then this method will suit you:
Via computer
This method will help you enter the recovery menu if the previous method failed for some reason. Connect the device to a computer using a USB adapter and specify "Charging only" in the connection type. Download the archive with the ADB program and unpack it into any folder, the path to which does not contain Russian letters. In the resulting folder, create a file called devices.cmd, where cmd is its extension, and write three commands in it:
- echo off
- adb devices
- pause
Run the created file, a command line will open on the screen with the following commands already written:
- D: \ adb> devices.cmd
- adb devices
- List of devices attached

Your Android device will automatically be transferred to the recovery menu, and the further steps you need to perform to reset are described above in the "Through the recovery menu" sub-item.
We enter Recovery Mode through the computer What to do if the password has not been reset
If you reset the device in order to remove the password from it, which you forgot, and after the end of the procedure, the system still asks you to enter it, that is, there are two ways out of this situation. The first - enter the wrong password five times, a message will appear on the screen stating that the device is locked for 30 seconds, as well as a button “Forgot your password?”. Click on the button that appears, you will be asked to log into your Google account, which was previously linked to this phone or tablet. If you enter the required account, you will be able to reset your existing password.
Recovering the password for the device through a Google account Reset password via ADB
The second option is to reset your password using ADB. How to install this program is described above in the sub-item "Via computer". When you're done with the installation, run a command prompt as administrator and run the following options in it:
- adb shell
- cd /data/data/com.android.providers.settings/databases
- sqlite3 settings.db
- update system set value = 0 where name = 'lock_pattern_autolock';
- update system set value = 0 where name = 'lockscreen.lockedoutpermanently';
- .quit
If these commands did not help, then use the adb shellrm /data/system/gesture.key command or adb shell
rm /data/system/gesture.key.
How to recover data after a reset
It was previously described that in order to save data, you must first create a backup copy of files or transfer all important items to another medium. If you have not done this, but at the same time reset the device, then most likely you will not be able to recover the lost information. But it's worth trying: get root-rights on the device, and download to your computer any program designed to recover deleted files on Android. For example, you can use EASEUS Mobisaver for Android Free.
Recover deleted files with EASEUS Mobisaver for Android Free You can roll back the device to factory settings in two ways: through the device settings or the recovery menu. Recovery Mode can be entered both from the device itself and using a computer. Before you reset the system, do not forget to transfer all important information to a reliable third-party media. ...
A Hard Reset, or Hard Reset, brings your device back to factory settings. In this case, all accumulated user data, including the address book, is deleted. In this article, we will tell you how to restore contacts on Android after resetting the device.
The address book
Using notebooks, in the digital age, has become out of fashion. All contacts are stored in the smartphone's address book. It records phone numbers, e-mail addresses and other necessary data. The more active the lifestyle that a person leads, the more various contacts he accumulates. The loss of these records becomes undesirable.
Restoring contacts on Android, in the event that the user has taken care of their safety in advance, is not difficult. Even accidentally deleted numbers and addresses can be returned with a high degree of probability.
Recover using Google
For owners of Android devices, a reliable and widespread method of saving contacts is associated with the use of the services of "Corporation of Good". To do this, you must have a Google account and enable the synchronization mechanism. A Google account, along with a postal address in the gmail.com domain, is created the first time you access the app store. Thus, a user who has installed the program from Google Play at least once has a valid account.
After resetting the settings on the device, you need to specify the account information and set up synchronization. The address book saved on Google servers will be restored to the smartphone in the form in which it was at the time of the last backup session.
If you have a desire to pre-edit the saved contacts, this can also be done using a valid account. You will need to go to the account settings using a computer and manually sort the data saved in the address book.
Backup copy
Another method for guaranteed restoration of contacts is backup. Many users turn off the connection with cloud services "Corporation of Good" to save battery power, preferring to periodically synchronize their device with a computer. There are several ways to create such a copy for subsequent recovery.
Manufacturer utilities
Almost all manufacturers of mobile electronics create their own software that allows you to back up data to your computer. Below is a list of proprietary software that performs these tasks:
- Samsung Keis or Smart Switch;
- Sony PC Companion;
- HTC Sync Manager.
Third party software
To create backup copies of contacts, you can use other programs specially designed for this purpose. They are initially released with support for devices from different manufacturers, and each update expands the compatibility base. Here is a list of the most popular programs:
- Helium App Sync and Backup;
- Titanium Backup;
- GCloud Backup.
After the device has been returned to its factory settings, we connect it to the computer and restore the contacts from the backup.
A similar operation can be done via Google. Using your account, create a copy of your contacts by exporting it to your computer or sending it to the cloud in the required format.
Data recovery software
The above methods are suitable for users who care about saving the address book in advance. Let's look at how to recover deleted contacts on Android when custom settings are reset and there are no backups. Even in such a neglected case, contacts, like other digital information, did not disappear without a trace. Recovery will take longer, but it can be done.
You will have to use special software designed for data recovery. Free 7-Data Recovery is considered one of the best in its class representatives of such software.
For the program to work, the device will need to be connected to a computer in USB debugging mode and start scanning. The numerical data that could be found will be displayed in the form of a list. You will only have to specify the ones required for recovery and wait.
Perhaps some of the contacts, after this operation, will have to be edited manually. Cyrillic characters, in some cases, are not recognized correctly.
Another representative of the software created specifically for such cases is Dr. Fone. The principle of operation of this software is similar. The connection to the computer is carried out using a USB cable in debug mode.
Data recovery performed in this way does not provide a complete guarantee of success. The operation of the programs depends on various factors. Influence can be exerted by:
- file system type;
- presence of errors in the partition table;
- the percentage of the media filled with data at which the formatting was performed.
- the main format of stored files.
There are other factors that can affect the quality of work with the file system and the integrity of the recovered data. In any case, if you set about recovery, it is better to return at least some of the information than to completely lose it.
Conclusion
As you can see, there are no hopeless situations. You can recover data even after performing a Hard reset. So that contacts do not disappear and do not have to resort to radical methods, think about choosing a backup method in advance. Cloud storage is not as scary as it seems at first glance. Data transfer with their help is lossless. Using this method of storing contacts, you will be sure of their safety and will be able to perform any operations with your Android device.
