If you are Bangladeshi then you might be using Ridmik Keyboard. Most of the people do. But you might not like the emoji on Ridmik . There are 75 emoji’s but most them that you don’t need. So you csn use this trick.
Things you will need is a Android phone, two apps.
obviously first one is Ridmik keyboard itself! the second one is APK Editor Pro. I’m not giving the links. You will find those two apps on Google Play Store or on internet.
