Sometimes, when you are using the emulator, even if you type English characters, the emulator will be suggesting based on some Chinese /Japanese characters (I do not know the difference between the two). To disable this you need to go to Phone Settings in the emulator menus and remove the Japanese IME Settings. The path to that is in the main screen, click on the up-arrow (seen at the bottom) to see the menu. Select “settings”, navigate to “Language & Keyboard Settings”, and uncheck “Japanese IME”. You will be back to English suggestions / keyboard.
