That is correct. Out of the 4, Indigo is the only one that has a unique texture.
Please refer to this website for more detailed pictures of SH-01G:
http://japanese.engadget.com/gallery/aquos-zeta-sh-01g/#!slide=2977524
Indigo= Rubbery
White= Glossy
Light Blue= Glossy with a certain texture(rubbery as well? I couldn't recall)
Pink/Red= Matte
Regarding that, my personal opinion is that all pictures will look crappy when transferred to PC?

Though I admit pictures shown on my SH-01G/4F looks really much better than on PC; and so is F-06E/2G.
Generally, I'll say Fujitsu takes better daylight pictures whereas SHARP has the upper hand at low lighting conditions.
(all these are my opinions and does not reflect the official performance)
F-02G pales in comparison in a few a few major aspects
(mostly battery for me)
1)
Battery usage for display
F-02G consumes a tonne of battery power for its WQHD display. In my usage, it consumes
at least 40% of my battery power (using GSM battery app) vs 18-24% for SH-01G. Display on F-02G is super crisp and beautiful but at an expense of battery. SH-01G wins by a landslide in display aspect. But hey, F-02G's display is really
beautiful!
2)
Battery usage for CPU
F-02G has a quirky CPU.
Feels as if it is a hot headed/blooded lad. It often throttles up even on simple basic usage (3C Toolbox app), resulting in intense battery usage and unsolicited heat generation. F-02G's CPU gave me a worrying and negative impression on Fujitsu's handling of its CPU usage; more often than not having its CPU run on high frequencies and load. In all, I will say that F-02G's CPU
usage and
handling is
poor compared to SH-01G.
You can say that F-02G is a Ferarri that speeds up really quickly, and having an excellent speed but poor mileage. SH-01G, on the other hand, is a mild docile Mercedes sedan that does what you need it to do. Reliable and lasting
3)
Battery usage when sleep/idle/screen off
F-02G has a pretty poor battery consumption compared to SH-01G(in my usage). Nearly 3/4 of its battery usage goes to its Kernel, and lord knows what Fujitsu is doing under the hood. SH-01G fares better in this area, which most of the usage being on Kernel & Android System. Battery usage and management is better in SH-01G compared to F-02G in this area.
(this happens to my F-06E as well)
4)
CPU
F-02G is really jiffy, responsive. Delays and lag are not in Fujitsu's vocabulary. SHARP on the other hand definitely has room for some improvements. Once again, of course, Fujitsu has a temperament, unpredictable and erratic CPU usage which often results in a poorer battery life.
5)
Heating
Talk about overheating! F-02G when under moderate to high load will bring your CPU temperature to a nice toasty 63-68 degrees celsius. You can literally feel the back of your F-02G heating up. Does not happen on SH-01G unless you are taking a 10minute WQHD video.
Pros of F-02G over SH-01G
1)
Snappy response
Touch or launch what you want and the 801 under F-02's hood will do exactly as you say.
2)
RAM
Has a really great RAM management. Apps resume quick and without the need to restart whereas SHARP often has to restart the app from scratch and has slower resume time.
3)
Looks
Premium built. Solid feel on hands. Love the metallic side which has an alluring sheen. Amazing built quality, nothing short of a well-crafted and design handset.
It is no wonder that it won a 2015 Red Dot Design.
4)
Picture qualities
Haven't really try out the pictures (phone is not with me anymore) but Fujitsu often takes really beautiful daylight pictures. F-02G will generally surpass SH-01G daylight picture qualities.
In all, F-02G = Luscious x gorgeous. Average battery life (sub-par if compared to SH-01G), great great performance and beautiful daylight pictures. It's humongous 3500mAh compensates for any higher battery usage than other mainstream phones.
