Microsoft lumia640 , has very good features ,but has some issue . it is getting hang multiple time in a day . service centers could not able fix the issue. and as per company policy they will repair the device but cannot replace it . from last 3 months they have tried twice to solve the issue but failed . now they are not replacing the device nor solving the issue. it's too bad.
