Why does the Voice Search fail to work with other language after updating TV software version to v6.2858?
This is due to a change in Google specification for Android TV. If your TV default language is set to English and you attempt to perform a Voice Search in other languages, the Voice Search function will not work (The corresponding text does not appear in the voice search box).
You can only perform Voice Search using the same language set on your TV. To change the language, please follow the steps below:
Press Home on your remote control and select Settings
Under System Preferences section, select Language
Select your desired Language from the list and press enter button button on your remote control
