arc S can not convince me completely

I had arc S on the basis of the many very good reviews ordered me here. Better said I have it in the contract with Debitel in the Vodafone network.
I can not understand the good reviews. Sure, this design is very good, the screen sharp and the touch screen responds reliably. But that was it almost. Unfortunately, the design takes its toll, the ergonomics are therefore bad - (! Finger acrobatics) the headphone jack on the side, the tiny camera shutter button and the screen lock button are poorly placed, the volume rocker is also a torment that aside. The keys have a bad or no tactile feedback. That the arc S has no front camera, is also a mystery to me. The SE neo - the "little" brother - has one. Well, so far you could have put all this in experience, if you had read all the reviews. In the store it drops a not so on, but in use already. Traderjob a creaking has not heard me.
But even that Android keeps - at least for Sony - some surprise ready. Let's take the contacts. The only be sorted by first name. How stupid is this going. If you want to use the arc S for Company contacts, you have to know all the names. Similarly, the representation of the address: street, city, state, zip code, as if is which later occurred, that there are ZIP and added the field. The highlight, however, is that you can store in the otherwise lush contact no birthday. Is apparently only at Sony way. The answer is a Geburtstagsapp here. Daduchus birthdays are also equal to about worn in aCalendar, which means that the field for birthdays also available at Sony, but is not visible.
Also, the MP3 player did not convince me. The functions are rudimentary - that's ok - but sound is only average (bland and not volume). Since my old 0815-Samsung sounds better by far. After what felt like 20 MP3 players Apps I am but then ended up in the top dog PowerAmp. He coaxed the arc S is the only one rich sound and powerful bass. The voice quality when making calls is otherwise good, even if the interlocutor sounds rather dull, but it is free from noise.
Also a step backwards compared to my 0815-Samsung is that SMS will ring only once. An audible reminder function does not exist. For a small LED, which can not be seen, of course, in your pocket flashes. Again, you have to back with an app (eg Missed Call Reminder) appeals.
The otherwise rapidly working arc S approved here and there times a respite. Especially when switching from the browser or "major" apps on the homescreen. Super slow is also the display of photos in the gallery. When opening pass before a few seconds until the image is displayed "sharp". So you have to be back with an app aids (eg QuickPic).
The Internet connection via Wi-Fi works very quickly, over HSPA the arc S is pretty lame but what disappointed me a bit because I thought with Vodafone has in Berlin a comparatively well-developed network.
In general, it bothers me also that the smartphone will be delivered with a bunch of useless stuff that you can not uninstall (rooting I do not want for the time being - loss of warranty!).
Conclusion: The arc S is not bad, but also not a superior smartphone. For a former flagship that is not enough. Since Samsung or HTC have more to offer. If I could stand again today before deciding I would not have taken the arc S.
This is the App Store Goggle filled so, no longer surprises me. This operating system lacks rudimentary functions that can only be corrected with these apps.
