It is a common stock editing function, and many third-party photo editing apps offer it.

Not only grey scale (you don't want either black or white, you want gteu scale) but sepia, wrinkled all sorts of effects. ol around in https://play.google.com/store/apps/...lp=ggEQCg5waWN0dXJlIGVkaXRvcg==:S:ANO1ljKzfFU

Knowing what phone you have is essential to give step by step directions.

I know on my S7 in the gallery if I view and image there is an edit button, if I tap that it opens and editor and I just select saturation and reduce it to zero.
