A few weeks ago new Google Photos features, including an image markup feature, were discovered by a Twitter user in the app code but had not been activated yet.

Now Google is officially rolling out the markup feature and it should be available globally on Android devices in the near future. The company has already amended its editing instructions for Google Photos accordingly.

The tool lets you draw on your images, choosing from several colors and two-line types, a marker or a brush. Those users who already have the function available can access it via an icon within the editing toolbar at the bottoms of the app UI.

Overall, this looks like a very simple tool that's not meant to be used for any complex image editing but will certainly be helpful in certain situations. The feature has not arrived on any of our devices yet but let us know in the comments if you've been able to try it out.
