Microsoft lumia is worst phone I have ever seen. At the beginning time I was very good, but month after month it got bad and worse. Its quadcore processor is good, there is no problem with it infact it is even better than other android phone of quadcore processor with 1.2 gigahertz. But talking about ram of 1 gb its not good because it get hanged after filled of 6 gb from 8 gb rom. If we close the uc browser while downloading something it get hanged and take several minutes to scan. So my advice is not to buy this phone at all.
