Description : My first smart phone was the lumia 630. As I get used to, windows mobile is the benchmark. There is an android mobile in the family as well, but I think it is quite gas to use and the lumia is faster.
Last Answer : I'm voting for windows, it really suits me. So much so that there are few apps, but e.g., navigating the map on a mobile level is unbeatable in my opinion. It handles well and even small category phones are pretty fast with it.
