Hi,
Emojis are now expanded, and are relocated to the microphone symbol on the "qwerty" keyboard. Simply longpress the microphone symbol, and you will get a block of the following symbols: microphone, stylus, clipboard, settings, emoji face, keyboard-for voice input, stylus input, copy to clipboard, settings menu, emojis, and switching keyboard between normal and floating. When you press the emoji symbol, you'll be blown away by the greatly improved selection of real emojis and an assortment of symbols/icons. You will see ABC, SYM, 5 symbols dedicated to emojis/symbols/icons-with each page scrollable for a large selection, and a backspace symbol last. ABC and SYM simply returns you to the normal keyboard input. Hope this clarifies the issue for you, and have a blast! I apologise, but can't help you with the Play Store issue ?
Blessings!
