Guide to unlock a locked Android phone with a cracked screen

Here, I am sharing few methods. They all work, but depending on the phone, you might have to try all to figure out which works with your phone.

Use OTG Mouse to input password on the locked screen

Almost every smartphone from entry-level category to the flagship supports OTG (On-The-Go), which enables you to add peripherals, USB Thumb drives, Mouse, Keyboards, etc. to your smartphone and use them to control your smartphone. So get an OTG adapter which suits your smartphone USB Port (micro USB 2.0 or USB Type-C), and then connect the mouse to the smartphone.

If your screen is partially visible, then you will be able to see the mouse pointer. Now you can unlock the device by inputting the password or lock pattern. If the screen became all black-ut and cannot see anything, you may need to move the cursor with some assumptions.

Use ADB Commands to input password to unlock your phone

As the Android Operating System is an Open Source as well as customizable from the root, there are several features like ADB (Android Debugging Bridge) which you can use to access the smartphone through several commands.

To use ADB Commands, you need Android SDK package installed your Windows/Linux/Mac system. You can download it directly from here and install it on your computer. You can also avail the Minimal ADB Fastboot Command line applications for the PC. It has same features but minimal in size. It also installs the necessary Android drivers for the smartphone.

Warning: Avoid doing this method if you are no expertise in ADB Commands and execution.

You can unlock any Android smartphone using ADB commands if the screen is locked with a PIN or a Character password. Follow the steps for unlocking the device.

Advanced users can also use it to recover data from the phone.
