What it does
This package is the viewer and editor for photos taken in Portrait mode, called Live focus on older Galaxy phones. From Gallery you can open such a photo and change the strength and style of the background effect after the fact. Device surveys show it on current Galaxy models. It runs only when you edit a portrait photo.
Also shown as Live focus.
If you disable it
The option to change the background effect on portrait photos disappears from Gallery. The photos themselves are unaffected.
