Why is my Galaxy C5 Pro keyboard not appearing for me to unlock and access the phone?

[Android Central Question]

My name is Martin Sigiara. Last evening I was uninstalling some apps, especially games; then I also disabled one app with a smiley face. A question came to me like "set to factory setting?" which I clicked OK. Now a Microphone icon appeared instead of the smiley face; I left the phone inactive for some two minutes then it got locked. Since then I'm not able to unlock the phone because the keyboard does not appear. When I swipe a text appears saying "Tap the mic button to speak".
At the lower I can see a keyboard icon, but clicking it does not pop up anything.
Only the emergency call screen can open freely.
Please help me on how to unlock and use my phone again .

Welcome to Android Central! Does this persist after a reboot? Or in Safe Mode? https://www.hardreset.info/devices/samsung/samsung-c5000-galaxy-c5/faq/safe-mode/

If it still happens, try connecting a basic USB keyboard via OTG cable and see if you can enter your password that way.
