Chrome on Android now offers a "Google Lens" search when you tap & hold an image. It's like a reverse image search but more advanced: it tries to detect what's in the picture and does a Google search on that.

It also tries to find similar images on the web, but it might not give you what you want. Some people disable it so they can get back to the old reverse image search, that simply tries to find other usages of that image.

EDIT: Seems like they now have an option to fall back to the old image search. It's at the bottom when you do a Lens search.

So for example if you take a picture of Lisa Millar (ABC newscaster hottie) and do a Lens search, it will give you all kinds of pictures of Lisa. But if you choose the bottom option to fall back to a Google Image search, it will give you other places where that specific photo can be found.

Interesting.
