Hi ALL,
I bought Nokia Lumia 638 from one of the online e commerce store 6months back . the main problem with this mobile is as it is a windows version of the mobile . many of the options are not able to understand properly and also many of the apps which are currently running around the market are not their in windows to download . apart from all of this net connectivity is hectic in this mobile as we recharge with 3g also it will take huge time download and sometimes the problem also their with our wifi too . our wifi speed is more than 20mbps eventhough mobile taked huge time to load or to download any apps or even to browse on some of the apps . my sincere advice is if you are already using windows version then please go and buy others request not to look in to this windows mobiles at all.
