Samsung Galaxy Grand Prime is a popular smartphone that comes with a lot of features. One of the most important features of any smartphone is its security, and Samsung Galaxy Grand Prime offers several locking options to secure the device. However, there may be times when you forget the screen lock password, pattern, or PIN. In such cases, you need to know how to unlock the screen lock on your Samsung Galaxy Grand Prime. Here is a step-by-step guide to help you out.

Step 1: Restart Your Device

The first thing you should try when you forget your screen lock is restarting your device. Press and hold the power button until the “Power off” option appears on the screen. Tap on it to turn off your phone. Wait for a few seconds and then press and hold the power button again to turn it back on. This might solve the issue and allow you to unlock the screen lock normally.

Step 2: Use Find My Mobile

If restarting your device doesn’t work, the next thing you can try is using Samsung‘s Find My Mobile service. This requires you to have a Samsung account and have previously enabled Find My Mobile on your device. Go to the Find My Mobile website and log in with your Samsung account credentials. Select your device from the list of registered devices, click on “Unlock my screen” and follow the instructions displayed on the screen. Once completed, you should be able to access your device without any screen lock.

Step 3: Use Android Device Manager

If you don’t have a Samsung account or haven’t enabled Find My Mobile, you can use Google’s Android Device Manager to unlock your device. Log in to the Android Device Manager website using your Google account credentials. Select your device from the list of registered devices and click on “Lock”. Enter a new password and confirm it. Once done, use the new password to unlock your device.

Step 4: Factory Reset Your Device

If none of the above methods work, the last resort is to factory reset your device. This will erase all the data on your phone, including your screen lock password. To factory reset your Samsung Galaxy Grand Prime, follow these steps:

  • Power off your device.
  • Press and hold the volume up, home, and power buttons simultaneously until the Samsung logo appears on the screen.
  • Use the volume buttons to navigate to “Wipe data/factory reset”, then press the power button to select it.
  • Confirm by selecting “Yes – delete all user data” and press the power button again.
  • Wait for the reset process to complete, then select “Reboot system now” and press the power button.


Screen lock is an essential security feature that protects your smartphone from unauthorized access. However, forgetting your screen lock password can be frustrating. In such cases, you can try restarting your device, using Find My Mobile or Android Device Manager, or factory resetting your device. Remember that factory resetting your device erases all the data, so make sure to back up your data before attempting this option.
