I have the phone for a week now and will even write a few words about it. My past: Several dual SIM mobile phones from China, ViewSonic V350. My requirements: Sim 1 = company card, no internet / Sim 2 = Private card incl internet. Perhaps the first design: Only available in white. Ugh, no one really needs! For processing: The back cover is really the cheapest I I've ever seen, if he is on it you realize it but nothing more. Otherwise, I have however not really complain much. Everything did not work properly with the other handsets goes, here properly! Anytime again written and hear what works and what does not at the same time: Phone Sim 1, Sim 2 = goes surfing Sim 1 phone, Sim 2 accessible = passes (is implemented with a call forwarding) Sim 1 phone, 2 sim phone = not going Sim 2 phone, Sim 2 = surfing does not work My application is ausschhließlich Sim 1 phone, Sim 2 surf, which works perfectly. I've never come during my many years now dual SIM usage in the embarrassment to want to make calls on two Sims simultaneously and when the internet disconnects while I on the same Card telephone is also ok for me. Maybe it can indeed other but I can not surf and phone at the same time. As I said, however, possible in two different Sims! Android 4 runs extremely smoothly on the device, but here each can take away the fear that the processor is too slow. The new Sony "James Bond Mobile" incl. ICS builds the menus the way slower than the duo, I find funny. Android 4 in my opinion is really well done and a big step forward compared to the old Froyo's. Battery life: for a smartphone of this class I feel the battery life as really good. If it can be really daring enough to get the battery is empty within a day course. With a somewhat conservative use (WLAN also try, Mobile Internet also came out, a few SMS, a few phone calls) does the battery also like once three days. That's better than average! The display is very nice and bright and it can not be bad things about it. The camera incl. Flash LED makes flawless images, but could be a little faster. I have after a long journey now found a really good phone, I, I can only recommend to everyone, from me there are very clear five stars!
