I agree, and think it have been so for a while at least with the better camera phones.
Sure they are not snapping Dslr worthy pictures, but for the level of expectations ppl in general have ( like not even bothering to tilt their phone the right way when they take pictures and make video ) then i think good phone cameras are more than enough.
The Galaxy Note 5 shoots video at resolutions up to 4K, and captures excellent audio. It has
optical image stabilization for movies at 1080p and below, so videos are smooth even without a tripod. The latest generation of Galaxy phones come with built-in live streaming to YouTube right in the camera software, so there's no need to fiddle with a separate app. Just log in, press record and that's it.
The dual-pixel sensor, Galaxy S7 Edge camera is the fastest phone camera available with larger 1.4-micron pixels and a f/1.7 aperture providing excellent low light performance.
The iPhone 6 has a 12-megapixel iSight camera with 1.22µm pixel size, backside illuminated sensor, Optical image stabilization, ƒ/2.2 aperture, Autofocus and a whole range of other features. It's considered a kick-ass camera.
Many of today's smart phones offer better image quality than point and shoot cameras from just a few years ago. They may not perform like a DSLR ( as they shouldn't be expected to) but some of of them can put dash cam video quality to shame.
The small lens and other components are hardly the compromise they used to be, so I could really envision a tiny remote lens module for an action type cam that performs pretty well.
