Why not Background blur option function in photo gallery of note 9??

This function is only for Back rear cameras

First of all there should me a minimum gap between the subject and background for this effect to work.
This option will work only with rear cameras. If there is a light source behind the subject there will be an additional option to change the background light pattern also

but why not for front camera? if other galaxy phones like A6+ have it

There is a new software update which started to rollout in Germany. It have a dedicated night mode for note 9 camera. Let's wait for the update and see whether the front cam will also get background editing feature.
