Why can't I unlock my phone?

My phone won't unlock for three days now all it says is " Unfortunately, Samsung keyboard has stopped.'' But the screen works perfectly

Turn off the device Hold the power+voloume up+home button.After 20 sec you should see a Screen with options like wipe etc
Use Voloume up button and voloume down button to select anr power button to confirm.
Go to Clear or wipe cache using the voloume buttons and select by using power button.
Confirm it.
Now go to reboot system and confirm it.
You should be able to type your password in.

I am So sorry The Keyboard Data Folder is Somehow Corrupted.
Now You have Two Options.
1:Learn how to Use adb Recover Your Data and Reset your Phohe.
2:Reset Your Phone.
3:Flash a New Firmware.

Android is fully compatible with USB keyboards/mice.

You could plug one of those in to enter your password and unlock it.
