I have the phone about 2 months and am very happy with it. I had already a Samsung cell phone so I had no problems with the menu. It is for me sowiso over other mobile phones the best menus. The switch between the two SIM cards is very easy with one touch the side of the phone and you can see that also on display very well which card is active! So I can only recommend the phone even though it's my first Dualsim phone!
