I dont know who are those people who love windows so much that they want that os in there smartphone when they have iphone and android in the market. I love windows for computers but for mobiles its crazy. First of all the build quality is so bad. So cheap material they have used for this microsoft lumia 535. Once I dropped and it went horrible. 1GB Ram is not alt all good. So many lags come when you use your device for multitasking. And whatsapp protection is not here? Is it a joke? If you install third party application then you have to open whatsapp from that third party application. But tell me one thing if somebody opens orginal whatsapp from your lumia? Who is going to open through that third party app? No protection what else you want?
