Re: Couldn't be happier with my Mate 20 Pro
I've just done the opposite - I went from a Samsung S7 to an LG v30 and now I'm on a S10 Pro - I figured for the relatively small monthly increment, I may as well go for the higher-rated battery.
Going from the S7 to the V30, there was a measurable improvement in photo quality, and for the "urban" photography I do, the wide-angle lens is an absolute marvel. However, the viewing angle for the normal lens was visibly narrower on the V30, so I often found myself having to take a step further back to get the same photo. Which sometimes meant I had to fall back to the wide-angle lens (with slightly lower quality and visible barrel distortion) or run the occasional risk of stepping into the road.
Since the S10 Pro has a wider viewing angle for both the normal and wide-angle lens, I figured I'd give it a go.
Unfortunately, it's a mixed bag. The normal lens has a wider viewing angle and a lower resolution (from 16mp to 12mp); between the two, this effectively cancels out any improvements at the hardware level - the test photos I've done are pretty much indistinguishable.
Also, the software is far less polished than LG's - I'm really not a fan of the sliding "ribbon" to switch between modes, and while the manual pro-photo mode is tolerable, there isn't an equivalent pro-video mode. On the LG, I could set the iso, framerate, monitor volume levels and tweak the microphone sensitivity: absolutely perfect for filming gig snippets when in my occasional groupie/roadie/scene-fan modes; by default, video cameras tend to screw up the contrast levels and completely wash out people's faces.
Sadly, on the S10, all I can do is tweak the lighting level and set the focal point. And the onboard editing tools are notable by their absence. As far as I can tell, all you can do is to trim the footage - looking around on Google, it looks like they used to offer a more fully-featured editing app, but it's not available for the S10.
For now, the wider viewing angles compensate for everything else. But it's been more of a sidestep than an upgrade, and I suspect I'll be getting itchy feet before year end.
Sadly, I don't think there's anything out there with a comparable wide-angle lens - both LG and Huawei have settled on 107 degrees - a significant step down from the 135 degrees offered by the original LG G5 and less than the 123-degree lens sported by the S10.
