Situation 3: Broke Phone with Smashed Screen

If you were trapped in this situation, you would freak out to get your Android phone unlocked. It would be a bit of problem for you, but if you have enabled the USB debugging option on your phone, it would be much easier to unlock screen. Luckily, creative solutions are also listed below to solve this awkward situation without turning the mode on.

Method 1: Using Android Debug Bridge

Be aware that USB Debugging option on your phone should already be turned on when you try this.

1. Download Android SDK package on your PC.

2. Open the Command Prompt (Ctrl+ R > type CMD > Enter) on your PC and change the directory to where the ADB file is located. Enter the following command– “cd C:/android/platform-tools” into Command Prompt.

3. Connect Android phone to your PC via USB cable and enter the following command– “adb device”. When your phone is detected, you’ll see some numbers in the Command Prompt window.

Type the following two commands. You’ll need to type in the second command– “shell input keyevent 66” immediately after the first one– “adb shell input text 1234”. Then replace 1234 in the first command with your actual password.

Method 2: Using USB OTG Cable

This method succeeds in working without turning debugging mode on, but only works with the devices supporting USB OTG.

1. Plug in an OTG cable (it’s available on Amazon or elsewhere) into the micro USB port on your device.

2. Insert a USB mouse into the other part of the cable. If your device is compatible with USB OTG, with the mouse accessible to your Android device, you’ll see a mouse pointer under the broken screen.

3. Please left click and draw the Pattern, or enter the password by clicking on the digits to unlock screen.
   

Method 3: Using Find My Mobile Tool

This tool is only for Samsung mobile phone in the case that you have formerly registered Samsung account on your phone.

1. Go to Samsung Find My Mobile and sign in with your registered account.

2. You’re supposed to see your registered phone on the left hand side bar, in the Find My Mobile account page.

3. Select “Unlock my screen” and select “Unlock” to wait a few seconds for it to finish. You will get a notification pop-up to inform you that your screen is unlocked.

This way is probably not able to unlock any Android phone, but you can give it a shot on the condition that parts of the touch functionality still work on your phone.
