Last month Adduplex has released Windows Phone statistics showing good growth of Lumia 920 in USA market. Today, they have teased with above slide which shows that WP8 has remarkably improved its share out of total Windows Phone users base in USA to 43%. It is really remarkable due to the fact that it has been hardly 2 months since WP8 phones are out in the market and WP7 phones are selling there for at least 8 months. The claim from Microsoft that WP8 devices are selling 4 times faster than the WP7 devices may hold some truth.
Adduplex is going to reveal the full statistics next week, so we will come to know how well the Lumia range is doing in USA.
Thanks Charan for the Tip.
