Google assistant began to roll out to android phones in the Middle East just recently, but not without problems. One problem that is common and that many people are encountering is that Google Assistant seemed to disappear shortly after being activated. Users would long press the home button launching Google Now instead of Google Assistant. Suddenly Google Assistant would disappear off the device without a trace. This is due to a change in the language settings in Google Now and probably the system language. The only way to get it back is to launch Google Now and go to settings, from there you should change the search language to “English”. You should also make sure that the system language is set to “English” as well. A couple of minutes after that and Google Assistant should miraculously reappear.
