Twelfth: noticed that as well. I am still questioning the amount of data the CMOS sensor is capturing. Many of the pictures I took with my OV have a file size almost 2x that if this phone. Other than having a flash. I have yet to take a picture that is better than my OV. Hopefully I will be able to do a fee tests this weekend.
Just kind if bothers me that a higher resolution picture has a lower file size (even on the 4:3 format). It means the OV had a lot of noise, or this phone is using a lower end .jpg compression.
Just doing a quick check it looks like the OV was using JPEG90 and not JPEG100 the file sizes are roughly double between the two (500Kvs 1MB). Based on the the few photos I have taken the picture aren't even being saved at JPEG90 on the 3D. Seems closer to JPEG80 as most files seem to less than 500k ( the one I just took in the dark of my dog with flash was 387k). I need to take more pics in full sunlight to compare, but I am not impressed so far.
It is nice to have a flashlight but that seems to be the only upgrade from the OV.

It's using more compression. JPEG100 is still lossy but it's fairly uncompressed relatively speaking. JPEG90 will chop it down a bit. If you notice, in the camera settings, there's no option for "Fine" detail or any other settings for picture quality. So yes, the images are more compressed than they could be and without a setting to change how much compression is used.
The two grid pictures I took indoors with a CFL bulb skewed towards warm light. What's interesting is that the red lines fluoresce a bit. It's a standard red sharpie marker, meaning deep red. The paper it was drawn on is white, but I expect yellow due to the bulb's color temp. It just demonstrates that the auto white balance is rather... well... e.
I wonder if we can have better results by using a different camera app altogether.
If noise were the issue, the file sizes would actually be higher. Pictures I've taken were generally soft all around but it doesn't look like it's due to smoothing. Best way I can describe it is that the in-focus range for the camera is extremely limited.
Sadly, still a step up from the Optimus Slider's (which is technically a newer model) camera. Everything on that had a tinge of blue and nothing was ever in focus.
Like most cellphone cameras, outdoor and bright and sunny light tends to produce the best images.
While playing around with the white balance and ISO settings, I noticed something when the camera was aimed at my LCD monitor.
You can see the direction the shutter rolls when you've got the camera aimed at something that also has a refresh rate. When holding the camera vertically, there is a slightly darker wave that rolls from right to left. (When in landscape mode with the button on top, that means it rolls from top-down.)
Knowing which direction the sensor scans can make for some interesting effects if you know how to exploit it (as I unintentionally did with my skewed building picture from the train)
In the end: Serviceable, good lighting will produce usable shots. Everything will likely have to be resized down to 1/4 for it to look nice. (eg, Facebook uploads) But still another crappy cellphone camera sensor.
