I sort of knew about it when it updated a week or so back but couldn’t remember how to use it so forgot about it! This is on an oldish Pixel 6 Pro.
Then got a prompt today to show me hiowto use it again… It’s great!
On any screen (works within every app I’ve tried but there might be exclusions in banking apps etc) hold down the home button and the screen goes a kind of night sky blue and you can circle any text or a picture and Google will kick in and “Google lens” it for you. For words you can just draw through the word/to get a definition or search in other ways.
So simple but utter genius! I’ve used it on the forum a few times already to check out who an author was id never heard of or a word/term I’ve no idea the meaning of.
Give it a try if you have a Pixel.đź‘Ť
