Google had launched its Hindi transliteration tool for Android named Hindi Input. It is an Indic IME (Input Method Editor) which allows users to type messages, update on social networks and compose emails in Hindi language on their phones operating with Android.
Google Hindi Input can work on all phones with Android, except the ones which does not have extended support for Devanagari Script. Google recommends that a user may install and use Google Hindi Input only if a Devanagari script such as नमस्ते can be read correctly on user’s phone.
