Advantages of Smartphone:
One of the main advantage of smartphone over digital camera is that it is really easy to carry everywhere and it is always there in your pocket and you can capture any moment or scene which is not possible with Digital camera because people don’t carry it everywhere with them, so for unplanned moments smartphones have the upper edge over digital cameras.
Another advantage of Smartphone is that we can post the photos and videos instantly on social media and we can share it with friends and family instantly but this is not possible in digital camera.
And like I’ve said earlier people tends to spend money on something that can be used for multiple purposes instead of something which have one specific use, so this is the main reason people in general buy smartphone instead of digital camera, but for the professionals smartphones can never take place of digital cameras.
Advantages of Digital Camera:
First and foremost advantage of a Digital Camera is the picture quality you get from it, the clarity and resolution everything is far better than the smatphone camera, so for professionals smartphones can never take place of digital cameras.
Another advantage of Digital Camera is in the post production process, we can save the raw files in digital cameras which is better for photo retouching and editing, we can also edit the JPEG format but the final result of raw file is more better than that of JPEG file.
Another advantage of digital camera is that you can change the lenses according to the need of our shoot which is not possible in smartphones.
In my opinion, if we think professionally smartphones can never beat digital cameras in terms of photography especially the DSLRs - because of the lens and sensor size as well as the shutter speed, light sensitivity, etc.
Smartphones have their own place and digital cameras have their own, at first place we should not forget about, that smartphones basically made for daily usage and not only for photography - Contrary to this, digital cameras are manufactured just for photography.
