[AC Question]

Hi, i'm Francesco from Italy, I have e Huawei Mate 9 since few days and I have a problem with the local search engine (the standard home style, not the drawer); when i swipe down on the home screen it's appear the text box and the recent used apps, but when I press a key digit the windows crash and it closes the search engine. Anyone have some suggestion please?
Thanks
