Kinda. The values are all reciprocal. While you can't stop down to f/16 because of the fixed aperture, you can increase the shutter speed to compensate. Assuming ISO 100, so an initial starting shutter speed of 1/100 and a phone with a fixed aperture of f/2, then you need to calculate the difference in exposure between f/16 and f/2, which is six stops. If you compensate by setting your shutter speed to 1/6400 (i.e.: six stops over 1/100) you'll be in line with Sunny 16. This depends on having manual control of your exposure and a phone with a shutter speed that goes that high, but I think most do.
