When clicking the battery saver it pops up a info saying some thing about how to save battery, and one of them is to disable Hey Google. Maybe is possible to get reed of that message ?
That is just a generic message that should be of no concern whatsoever.
Note the use of “like Hey Google”. It is informative and nothing else.
Seriously hope there’s no assumption that “Hey Google” exists as a feature in /e/OS. Be assured it does not.
