beautiful design with weaknesses in terms of performance

Let's. One of the positive aspects
+ The device looks nice and fits comfortably in your hand make rearward rounded knew their service. Visually, it works by slimmer.
+ User interface as usual with Samsung very simple, clear and thanks to Android 4.0.4, many settings are very easy and fast to reach.
+ The duration of the battery is the screen size of 4 '' well, at ease of use (a few short telephone calls, now and then surfing, daytime aggregate active) can be two days certainly create (thanks 1500mAh). Increased use, however, ensures that you also need the box after just one day.

Evaluate as neutral
° the dual SIM works as it should. It is accessible on both numbers, unless you just phoned. Call waiting is not working until further notice, and not without causing costs on both cards. Ie, when I call on SIM1 and someone calls on SIM1, then I get a knock or the caller is transferred to the mailbox or receives an indication that I'm not temporarily unavailable. All depending on the setting of the provider of SIM1. Will I however call during a call on the SIM2, then sounds again the message of accessibility or the forwarding to the mailbox. Besides I registered my numbers of the cards in the device, then the smartphone is able to transfer the call to the SIM1. This process costs money. The whole makes then but again only make sense if I have call waiting enabled on the SIM1. Otherwise, the caller ends up SIM2 in the mailbox or in the announcement of the nice lady that you can not be reached. In any case, we will pay once for forwarding
Attention exactly here may just incur costs and depending on your phone even if you have a telephone flat rate if the provider just exclude a transfer of the flat rate. Nevertheless, one can use the dual SIM very good and if one enters any numbers also will not be charged. Data connection always works only on a SIM card with 3G, the other creates then only 2G. Samsung has built here probably only a unit that 3G can. Interfere unless if you use a card for the data network and the other to call. You need to both SIM cards the data connection, then a just very slowly.

As negative perceived:
- Is the worst of all, that no programs can be pushed to the SD card from the phone memory. Also with any program. The phone's internal memory is divided into system memory (about 1.5 GB) and the phone's memory (about 2.5GB). The phone memory to check out the "SD card". Here, applications are stored. This works as long as you install any great apps. But if you have one or the other graphically demanding game that is already tight. If you come with a Navisoftware with maps for Western Europe is Feierabend. It does not fit it. You can reverse the mobile rooting and during start-up naming the folder for the phone memory (mnt / sdcard) and the SD card (mnt / sdcard2) Now that solves this problem, but is not feasible for everyone and can lead to warranty loss ,
- What is often noticed that the mobile phone with the processor comes quickly to its limits. The phone hacking and even with a benchmark test Unfortunately, I realized that my old Sony Ericsson Mini Pro (also 1GHz, 500MB RAM) with subsequently aufgespieltem Android ICS (4.0.4) considerably better results than the Samsung Galaxy S Duos.
- Browse by Dolphine also depends very often and a side building lasts even with the best wireless connection partly a 3-fold longer than in the Mini Pro Xperia E Dual or (also same equipment)
- The price of 220 for a subclass phone is already too high. Other providers manage the dual SIM segment with comparable and even better facilities to offer more favorable phones (Sony, Mobistel, Alcatel)

CONCLUSION
Those looking for a smartphone beginner, a dual SIM mobile phone, which will weaken the safe in the performance not notice all too large and will also install only a few small apps. So if you value it places a device from one of the market leader to acquire and can live with the shortcomings, to may like to buy this device.
I personally recommend it not for users with extensive requirements. For this you would have to take too many compromises and I would not at this price. Who the manufacturer's name does not matter, which should be the Alcatel 992D View times or perhaps even wait for the Mobistel F1, which is the 4 '' variant of T1 and in April is in Germany on the market. If it brings the power of the Mobistel T1, then this will certainly be worth buying.
