DSS mobile I have been a week and am super happy. Everything goes smoothly, ie smoothly. Moreover, the voice quality is absolutely fine and should be better than the Galaxy S II. Meanwhile, the battery is also well-conditioned. For "normal" use, phone, incl. Internet surfing, emails and a few apps to run, he holds two days. I bought a SanDisk Micro SDHC 32GB Class 4 memory card for about 19 to. Even with the map all goes fine. Even HD videos without stuttering. Had I only considered the Galaxy S II to buy. But do not see any advantage which could justify the 150. From me there for a strong buy recommendation for the Samsung Galaxy S Plus!
