That is a chinese dual sim phone, the names alone should tell you they are not from traditional manufacturers. You will have serious with supports like batteries and other parts that goes bad and need replacement. If you have a habit of dropping your phone then you should not think of buying a smart phone for if you do get one for 15k chances are it's going to be a touch screen and you whole 15k will shatter with just one drop.
