just looked at the specs, no portrait camera so probably go with the main (not the wide one) and if you can set the f-stop (aperture) to the lowest number you can. test it out. closer you get to the subject more blur you will get on the background. then there is probably an option to blur it more (most phones do it in a portrait mode chosen in the options)

you could probably do a lot with your macro camera for small objects.

I found a motion blur option and tried to take a picture close up. I am starting to get the effect that I want. Not a great picture but I think it shows it can work although in a limited capacity on a phone.
