[Skunkworks] Genuine Dual Sim

hi all, Being searching for a genuine dual sim phone and came across Samsung B5722, but from reviews online, the phone seem to have lots of issues especially on response while writing messages and using its apps. Has anyone used it and what is experience like ?? What other Brands would you recommend with a dual sim, 2.0+ MP camera, supporting 3g networks and WI-FI, touch screen or qwerty keypad?? information on this will be highly appreciated.
