Is there a function to have an intuitive typing when writing a word, like google
The spell checking and suggested word completion is part of the operating system (because of the language selected as preference in the settings) and is interfacing through the virtual keyboard. I trust you will understand that it would make an app properly huge if it was to come up with its own implementation of spell check and have a complete dictionary, so it only need to exist once in the system, at the level of Android itself.
I you fail to see suggestion when you type, it is because you have not enabled it or that your default keyboard widget does not make use of the feature. I use “hacker’s keyboard” in all my Android devices ( https://play.google.com/store/apps/details?id=org.pocketworkstation.pckeyboard&hl=en_US ) and it works just great for me in this respect.
