As a rule, a cell phone is able to keep up-to-1000 caller numbers at a time. When the number of call history exceeds, the redundant disappears. Or, somehow it happened that call history has not yet been saved to contacts right after deleted. Or data lose after factory reset. In such cases, how do you view call history for unsaved numbers, be it incoming or outgoing?
Before we get down to this question. Perhaps you might be wondering whether you can retrieve and check deleted history from Android when they're unsaved? The answers is yes, but it works only when the data have not been overwritten. So, please stop using your Android to do any thing and stick with the solution below.
Android SMS Recovery is an application with which users can bring their lost data back. It works as a deleted call log recovery app, even when you don't have a backup file. It's now available on retrieving deleted call log on Samsung, Nokia and so on from SIM card or memory card without a hitch. By the way, if you're looking for the way to restore deleted call history on iPhone, take this link to redirect what you desire.
Note: It is advised that an Android data backup should be performed, so that when important things are accidently deleted, they can be retrieved. Because, still, there is a chance that the missing files can be replaced by new ones and will never be restored even with Android Data Recovery. (Also, that means you should stop using the phone when deletion happens.)
Step 1. Plug the Android Handset in and Tick USB Debugging
Make sure that there is still over 20% battery power left and launch the software. It will detect your device when you get it connected. Or, this interface can be seen, asking you to enable USB debugging. If you don't know how to do it, follow the details below. Otherwise, skip to Step 2. This is the way for Android 5.0 to Android 9.0/Android 4.2 to 4.4.4:
1. Go to "Settings" option to enter "About Phone"
2. Tap "Build number" for several times until getting a note "You are under developer mode"/"You are now a developer"
3. Back to "Settings" to click "Developer options"
4. Tick the box in front of "USB debugging"
Step 2. Choose File Types and Scan Mode
The application allows you to select among eight kinds of content, which is displayed in the picture. Tick "Call Logs" and tap "Next" on the bottom right. (You can also check other items if you want.)
Step 3. Tap "Allow" on the Phone Screen and Scan the Handset
Android Data Recovery will start to analyze the phone. And, after a while, you will see this window, meaning you should go to your device and press "Allow" when a SuperUser request pops up. Tick "Remember", or you may need to tap the button "Allow" for several times. Next, wait until data scanning is done.
Step 4. Tick Deleted Android Call Logs and Restore Them
The result is shown as the following. Click "Call History" to see the details on the right. (Black stands for existing items.) You can make use of the switch on the upper left to view deleted numbers only. Finally, check the specific ones you want and click the button "Recover" to get call logs in Android.
