Data recovery on Android is very actual topic and I have been asked more than once to describe in detail how you can recover lost files, images, videos, etc. There are many useful programs and today I will talk about one of the best - 7-Data Android Recovery.
7-Data Android Recovery is a fully Russified and generally intuitive program. Basically, you just need to follow the prompts and nothing more.
Well, we have connected the smartphone or tablet to the computer via USB, enabled USB debugging, now we need to open the installed 7-Data Android Recovery program. You will be greeted by the main menu of the program, where we are interested in the “Next” button in the lower right corner. Click on it.
After this, you will see a list of drives in your device. There are two options: internal memory and memory card or only internal memory. Select the drive you need (click on it) and click “Next”.
After this, a full scan of the drive will begin and at the end the program will display a list of all deleted, lost or formatted data and files.
To restore a file or folder, you need to select it and click “Save” in the lower right corner. You can select several folders or files at once - to do this you just need to check the box. You can also preview documents, photos and other media files before recovery.
I’ll say right away that it’s best to restore files to a computer, and only then transfer them to a smartphone or tablet. Also, the program cursed when I wanted to save files to a folder in Russian, so rename its name to English.
Due to various failures of equipment running on the Android operating system, or erroneous user actions, sometimes important data is lost from the device. This can be video and audio content, photographs, contact information. Therefore they are popular various applications to recover deleted files. One such program is 7 Data Android Recovery, which has good functionality and a user-friendly interface.
Any software designed for data recovery uses various algorithms. Loss of information and files can occur due to the following actions: accidental deletion, malfunction of the gadget’s flash memory, operating errors operating system. The operation of file recovery means finding data remains, extracting them and correcting them.
Android does not use an encrypted file system, so deleting data does not actually mean destroying or changing it. In fact, the file is simply marked by the system as deleted. That is, the data does not disappear, but the place where it is located may be overwritten. Since overwriting does not occur immediately when a file is deleted, successful recovery is possible in almost 99 percent of cases. Moreover, the more intensively the OS is used after deletion, the less likely it is to recover information.
It is more difficult to remove it if damaged file system or full formatting. In this case, applications use a search algorithm based on signatures - unique identifiers. For example, 7 Date Android Recovery sequentially scans all memory according to the principle of antivirus software, identifying files using the necessary signatures. If the file is also fragmented (broken into blocks of different lengths located in random places on the disk), then the application has to supplement the signature search with information from the file system.
This operation takes a long time. Due to the difficulties in supporting various signatures, there is a certain limitation on supported formats. In order for the OS to navigate the information located on memory cards, it creates a file that indicates which sectors are occupied by the data being sought.
Android Data Recovery begins its search from the location of the beginning and end of the file. The data size is determined by analyzing the title or reading the sectors following the title. But in any case, the result of recovery largely depends on overwriting the file system and fragmentation of partitions.
Features and Disadvantages
Like any program, 7 Data Recovery has both advantages and disadvantages compared to its counterparts. But it owes its popularity precisely to the predominance of positive opportunities. It occupies a leading position in the ratings of various publications and user reviews.
The advantages of the application include:
- recovery of files after exposure virus attack, deletion or formatting;
- finding and returning the partition structure;
- ability to work with both external and internal memory of the Android system;
- search system with filtering according to various criteria;
- sketch preview of graphics before restoration.
Among the advantages of the program they also highlight intuitively clear interface and good Russian-language localization. In addition, they note the presence of a convenient recovery wizard, a separate function for finding media files, fast work when decoding data encrypted by viruses. Users note quite high degree recovery of lost information.
The disadvantages include the rather high cost of activating full functionality. This is due to the fact that the utility is distributed as shareware. That is, it can be downloaded and installed for free, but it will be impossible to return data exceeding the total size of one gigabyte without purchasing a license.
Installing and using the application
Android memory data recovery is done using personal computer. The installation files are downloaded to a PC, to which a smartphone, tablet or other Android device is connected via a USB connection.

It is important that the utility can work not only with Android, but also with Windows and Mac.

Connection errors
It happens that 7 Data Android Recovery does not see the phone or other gadget connected to the PC. Most often, this situation occurs due to the fact that the “USB Debugging” option is not enabled on the device. To enable it, you will need to go to the device settings and select “For Developers”. By default this item is hidden - for it to appear, you need to do the following:
- In the gadget settings, find the “About phone” item and select it.
- In the list that appears, click on the “Build number” line seven times in a row.
- After the notification “Congratulations, you are now a developer” appears, go back a step.
- Find the “Developer Mode” item and enable debugging there.
If debugging is enabled, but the device is still not detected by the program, then possible reason There may be outdated or missing drivers for the gadget. It is recommended to go to the website of the smartphone or tablet manufacturer and download and then install the package latest version drivers. But there is also a possibility of incorrect operation of the Windows OS, namely the software implementation of support for USB hubs. Therefore, it is worth updating or reinstalling the drivers on the motherboard.
Except software problems, there may also be hardware ones. These include: damaged USB cable, non-working ports on motherboard computer or the device itself, the “dump” of the internal memory in the Android device. When using cords Bad quality The PC does not detect the device due to weak signal, so you should only connect to the rear ports of the motherboard.
