The answer to this question depends on different factors.
For any scenario, there is one crucial thing you need to understand:
Data in an Android phone with a screen lock is directly unuseable, let alone retrievable. You can't even enable USB debugging on locked phones.
So if you're aiming at recovering data from a locked smartphone, it will require you to unlock the Android screen first.
And there are three ways to unlock your Android device:
The first two options will not touch even the tip of your data. You'll get your files as they were.
However, the third option wipes Android's storage clean.
And it is important to note that in case you lose data from Android's internal storage, and not from the SD card, the recovery after a factory reset is difficult.
Not many programs can find a way around such an issue. And if you find such a program, it will require you to root your phone, which is another difficult task to execute.
Why is it hard to Recover Files from Android Phone Internal Memory?
It is difficult to access the internal memory of an Android device.
When you connect an Android to a computer, the system opens it through MTP (Media Transfer Protocol). The files in the phone storage are mounted as a separate disk, that a Data recovery tool has a difficult time to go around it.
If your data is on an SD card, and you factory-reset your device, data recovery is nearly guaranteed as a recovery software can readily access it and scan the lost files.
Plenty of ways can help you unlock the android device without touching even the tip of your data—methods like Unlocking with Google Account, or find my mobile.
But some of the fixes, like factory resetting, will cause data loss.
Unlike iPhone users, nearly all Android users don't execute a regular backup.
So when Android screen locks, the best recommendation to unlock the phone without data loss is to use the Google Account password.
And to use Google account to unlock an Android device, you must have set and signed up before you locked the smartphone.
Here is a step-by-step procedure to unlock Android device without data loss:
Step 1. Navigate through your locked screen for the "forgot password?" function, and tap on it.
Step 2. Your android will ask you to answer the recovery question you used to set your Google Account. If you can remember it, key it in, and your Android will unlock. You can now access all your data and set a password you can remember.
Step 3. If you don't remember the answer to your recovery question, input any password five times to invoke the "Forgotten the password" function.
Step 4. Your phone will ask you to input your Google Account and password and log in. This action unlocks your phone's screen with no data loss.
If the above method doesn't work for you, because you do not remember your password, try the next step. It should work for you.
Factory Resetting is another option to unlock Android devices.
The action undoes all the settings, wipe all the data, and return the phone to the manufacturer's initial settings.
The only problem is that you might lose some of your data permanently.
Since your screen is locked, it is a pretty mess that you cannot factory reset from the Settings menu.
You can only factory reset it via Android's Factory Reset in the Recovery Mode. To access the Recovery Mode, you'll utilize the buttons of your phone.
This screen-unlocking method removes all your data from internal storage.
Step-by-Step Procedure to Factory Reset Android Device
Step 1. Turn your phone off.
Step 2. Press and hold the Volume down button and the Power button simultaneously until the phone turns on. This opens the Android boot screen.
Step 3. On the Boot screen, use the Volume down button to move down until you highlight the Recovery mode option.
Step 4. Once you've highlighted the Recovery Mode, press the power button to initiate the Recovery Mode. You should see an Android robot.
Step 5. After you've access the Recovery mode screen, press and hold the Power button, and while doing so, hit the Volume up button once, then let go of the power button.
Step 6. Use the Volume down button to move down until you highlight Wipe data/factory reset option. Select it using the Power button.
Step 7. Then hit the Power button to select the "Reboot system now." Your phone will restore to the form it was when new.
