This DATA WIND tab is very bad for my life.Because I buy in four mounths back.This tab is very vast.This tab like a ordnary tab with out any facilities.we say that it is good saft ware in tab.This tab is no usefull for any thinks.In this tab we can say it is the signals strength for this tab.There is no proper clarity and proper connection setting to this tab.while using internet the tab gets heated and charging levels will be decreased.so, any one can buy this tab no, problems.But I faced in this tab so, many problems.
