Emoji Keyboard - CrazyCorn is a free Android app developed by crazystudio. This app allows users to input emojis in any app and comes with an array of features including beautiful keyboard UI, gesture slide input, and custom personal fonts. Emoji Keyboard - CrazyCorn supports English and many other languages. It also offers three different emoji styles: colorful, Android 4.4, and black/white. However, only two pages are available in the free version. Users can customize their keyboard theme color, key text, and background color, suggest and preview colors, and set their favorite picture as keyboard wallpaper.

The app is easy to enable and set as the default keyboard. However, users with Samsung S3/S2 or other devices may not be able to see black and white emojis and will need to install a free font to do so. Additionally, users with Android versions under 4.1 may not be able to see any emojis. Overall, Emoji Keyboard - CrazyCorn is a great app for those who love to use emojis and want to customize their keyboard experience.
