Phone locked and keyboard not working

[Devika_shah]

My Samsung keyboard had stopped working. So I was using a playstore downloaded keyboard. Accidentally I deleted the temporary keyboard (playstore downloaded) and locked my phone. My phone is secured with a password. And now since the Samsung keyboard is not working and I do not have a working keyboard, I cannot type the password and unlock my phone. What do I do? This morning with the help of Google play on pc I installed two keyboards on my device. But my default keypad is the Samsung one. I don't want to do a factory reset. How do I change the default keyboard and unlock my phone?
