[LG G6 Questions and Answers] maruichan:
These are not bad shots. The backyard one could probably use better lighting. With most shots, it's all about what your lighting is. I do find the LG app does not handle Levels on automatic as well as I'd like. "Gamma" doesn't really fix this. You can go into Photoshop though and fix this easily. They get good midtones, but it has trouble getting the deep blacks. That's my biggest complaint. The camera does seem to be "light hungry", but only a little bit more than my S5... though Samsung to me can be very overprocessed. Especially with color... I'm tempted to throw some older images and newer images into Histogram. When there is abundant light, it's about the same... I can boost blacks in Photoshop though just a tad and it'd look like it came out of a Samsung (but with better midtones).

As far as the "fuzziness", that's likely due to a camera sensor and how it particularly "describes" details. It being a cheap camera put inside a cell phone, it's only going to do so well. I notice in areas of low light, the sensor "makes up" some areas with a bit of wash/gradient texture. This is very common with camera phones and webcams.

If you're expecting this to be a photography enthusiast phone and you're very particular, then you should probably get a different phone tbh. I haven't looked into Samsung since S6, so I have no idea how their algorhythm fairs over the details, but I imagine it has not changed much. I am happy with the wide angle on the LG. It is annoying that I have to adjust some shots, but I'm a Graphic Designer by trade, so it's not much trouble for me to modify in PS or to use an app I have installed on my phone... if the subject of the image is that important to me. Most of the time it's just a minor Levels adjustment required, maybe bump Saturation a tad, but most shots don't need much modification. This is again where editors come in handy and again--cameras are just a tool... they're only going to work as well as the user, not to mention your lighting, your composition, your focal point, etc... I don't think changing the hardware of the phone will matter much, though out of the box Samsung handles "auto" much better... but then they also boost up colors massively, are less accurate whereas LG is very close to what I achieve with a hardware calibrate. So while it's more "honest", it's not necessarily as pretty. I understand this. So if you want easier shots without all the hassle to tell your story, then maybe go to Samsung. If it's breaking your heart that much, maybe even get an S7 since pretty much the camera in it is the same.

I did look into a third party app for the camera and played with a few. I'm sure if you find a good one that handles RAW (last time I checked, most cameras were crap :)), then you've got a winner because then you can adjust the image before software "flattens" the pixels.

But really, your pickiness sounds like you really should start a penny jar for an SLR. You can get a used SLR for about $700-800 if you watch around the time when school semesters end/begin. Of course over time you will spend a lot more in lens. I intend to get one in the near future, but if I spend that amount of money, it'll likely be something that'll last a really long time... so maybe something higher in MP so I can do bigger prints. Anyway, I can justify it because of my trade, but the other reason to meet that goal is so I can take very good shots when we go to New Mexico for our little geological adventure. Other than that, don't sweat it... that's why Photoshop exists. If you're truly a "dedicated" photographer, then Photoshop + Lightroom will make easy best friends for you. (If you don't use PS, then look into "Affinity Photo")

Edit: BTW, look into another app for panorama. I'm sure there are plenty. I used third party before it was "built-in"
