Truly want good photos get APSC or FF sensor cam with lenses, and obey the photo rules in iso, shutter speed and aperture there is just no comparison.
Look at the new Xiaomi candy modular concept... needs adding 35mm f1.4 laser link lens also. Even those with high end FF cameras, all also depends on personal skill level, experience and photo composition.
This device is great in what it is, futuristic, super slimness when folded, yet a powerful multi-tasker on the expanded screen, and takes great photos. The cases as with all cases add bulk sure but it assures protection in our investment.
Summary is buy what you like and afford... Why waste ur own time then comment buyers remorse. Any purchase is a lost after resold, don't buy if don't wanna lose any money. There are no one size fit all... Candy bar phone photos however the acclaim, are also computer processed and over hyped
