Samsung just updated its proprietary Galaxy Enhance-X app with some powerful tools.
The updated version 16.3.00.31, available on the Galaxy Store, adds a new interface, as well as the ability to edit videos and documents, not just photos.
The new interface is organized into three tabs – Plugins, Home, and History. The first offers add-ons, currently three – CinematicGlow, FilmStyle, and SkyGuide. These affect images with various effects and filters.
The extensive photo editing tools are still here – you can crop, rotate, denoise, remove reflections, fix moire, sharpen (or fix blurred photos), adjust HDR strength, and more.

What’s new is the ability to edit documents. You can convert docs into JPEGs or PDFs, also enhance colors, annotate, translate, crop, etc. There’s even batch editing.
As always, Enhance-X is a Samsung-exclusive app.
