Without a shallow depth of field is impossible to create the Bokeh effect. But don't worry; there are ways to achieve the Bokeh effect with a smartphone camera. Wide-angle lenses of smartphone cameras have a focal length between 26 mm and 35 mm depending on the model and manufacturer. The good news is that you can emulate both depth of field and bokeh effects using smartphone apps. Smartphones with a multiple camera setup, which allows them to calculate depth in an image, are generally better at creating natural looking bokeh, although some single camera phones like the Google Pixel range also do a good job.
