But this one is very good:

And it's clearly better than the iPhone.
All computational bokeh methods have flukes and failures, including Apple's. I've seen trainwreck bokeh done by iPhones too. The algorithms they use can be thrown off by some minor detail.
You just re-take the shot, perhaps change the angle a little bit. On my phone (P9) sometimes I can fix it by changing the focus point and the aperture effect, sometimes I just retake the shot and it works fine the second time.
It ain't as good as a DSLR, but I'm impressed with what modern smartphones have achieved so quickly.
