Photography on phones

[XcityX]

Hello. I was looking around everywhere but I can't find the solution anywhere. I'm starting to see a lot more selfies that look like this:

Are there any apps on android that can help me achieve that DSLR-like background blur while keeping me in focus with my front facing camera? Or at least give me an option to add a blurry vignette to the image?
