I recently encountered this situation; I accidentally restored the factory settings in my Samsung C5. All the data in my Samsung C5 was deleted, and I didn't back it up. Can I recover the data?
In addition to Samsung C5, if Samsung C7 and C9 users have encountered this situation, you can use this method. Well, then I'll show you how to use dr.fone toolkit - Android Data Recovery to restore phone data.
Step 1. Connect your Samsung C5/C7/C9 to the computer
Firstly, you need to download and install dr.fone toolkit for Android on your computer and run it. Next, find and click "Data Recovery" from the main interface.
Then, use the USB cable to connect your Samsung C5/C7/C9 to your computer. Before the program successfully identifies your Samsung C5/C7/C9, you need to open the USB debugging on the phone.
PS: If your Android os version is 4.2.2 or above, there will be a pop up message on your Android phone, tap on OK to allow USB debugging.
Step 2. Select file type to scan
Then, in the new window, you can see all file types, by default, all items are checked. You can select the file type you want, and then click "Next".
Step 3. Select the scan mode.
Next, you also need to select a scan mode to scan the phone data. In the new window you can see two modes, namely, the "Standard mode" and "Advanced mode". Please click on the one you want, and then click the "Start" button.
Note: There might be a Superuser authorization appearing on your device during the scan. If you get it, click "Allow" to continue. If not, just skip this step.
Step 4. Preview and recover data on Samsung C5/C7/C9
After the scanning process, all the data will be displayed in the window; you can preview them on by one. When you find the files you need to recover, check them and click "Recover".
