I just bought in the US two unlocked DUOS, after reviews that mention good connectivity. Both of them now use multi-national SIMS. I got one black and one white SM-G7102. There are, besides the colors, some unexpected differences between them. The black one could be upgraded to 4.4.2, the white one cannot be upgraded beyond 4.3 as the most recent OS. Of course, also Baseband version, Kernel version & dates, as well as Build number are different. Does anyone know why this is? I notice little difference between the two, but some of the menus are different. The white one has a European power connector, the black phone has one with two horizontal flat prongs, a model that I've never seen before in my travels.
I've used the phones a few days now and am happy with easy of use, clarity of screen and robustness.
So many issues arises after updating to kitkat.. Just wait the new version of android. It will come out very very soon.

The phone is good, but seeing problems lately, it takes forever downloading apps. Wifi connectivity is not that good, camera is bad, not crisp or sharp. Poor sunlight legibility. Cant see anything under the sun. Its dissapointing buying this. I will now switch to LG.

You have to perform a calibration to your phone battery.
And you can also upgrade to the latest version of Android.
My Battery takes forever to charge. When it charges up to 94% it will pause charging for a very long time before it'll get to 100%. In all, it takes about 5 hours to charge fully.
During the incoming calls the volume starts very low & automatically rises up is this normal?
Can i transfer all my photos and songs to SD card?? Because I'm gonna buy this phone
