I bought this recently. It has just been 6 months but now the display has stopped working. Also in this experience Nexus 5 D821 battery back up is also few hours. that why I am crying. this is very bad.
Final some peoples also said this is the Worst phone ever come across. My friend also got motherboard problems. He just replaced twice and still it does not work. and also I found sometimes Nexus 5 D821 model sleep and wake button is stuck. so beware this product.
