No.
A) It's not convenient to carry around a separate and dedicated filming and photography device (I lost capturing so many good moments back in the day by not having my camcorder or still cam with me at all times like you do with your smartphone)
B) I go to a lot of events that only allow photography and filming with phone cameras and do not allow dedicated cameras inside the event so I need my smartphone to have the utmost photo and filming quality.
C) One of the main features of a modern smartphone is the camera and on a flagship phone that's marketed mainly for it's camera some expectations need to be met.
D) I wish we would all stop calling these powerful smart devices phones and take the phone part out of the name all together because they're so much more than just a phone! They're a HD camera, they're a GPS, they're a music player, they're a gaming machine, they're a video player, they're a web browsing device, online banking, etc.etc.etc.
If you bought an Ultra and don't care about camera quality and only bought it for a phone then I think you wasted a great amount of money on a smartphone when you could make phone calls on an old S5... why did you waste money on an S20U just to make phone calls, lmao.
