Stick search instead of emoji

What's super annoying is, that it happened in the past, then it got back to normal (except in a few chats). Now a few days ago, during typing, it suddenly reappeared, and now in all of my chats.

I'm suspicious, that it can be changed in the chat somehow, and I accidentally swapped it.

Also, I'm not willing to get any addon or new keyboard, I want to get it back to normal. It happened before, there must be a solution to it.

Please, help!

I don't think that you can delete that. As for me, I don't know how to so I just lived with it until I got accustomed to seeing it there. Sometimes it still annoys me but at times, it also comes in handy.

You can use advance keyboard. I download it from Play store. It shows emoji near the text typing space. I did the same and got solution of this problem.
