Alan Mendelevich from AdDuplex has tweeted some teasers from their monthly state of Windows Phone survey collected from their Windows Phone ad network.
The teasers are:
Taking them from the top, we can seen the NL 520 has continued its ascent, if slightly slower, growing from 18% last month to 20% of the whole Windows Phone market, and from 27% to 30% of the WP8 market.
AdDuplex’s data also shows that there is a new second most popular Windows Phone in USA, and that MetroPCS now has 5% of the market. Given that MetroPCS is selling the Nokia Lumia 521 I suspect the Nokia Lumia 521 has displaced the Nokia Lumia 920, which had 16% of the market last month. The device is really showing itself as the little handset that could.
Other titbits is that Nokia continues to massively dominate the Windows Phone market, edging close to 90% of Windows Phone 8 handsets, at 88.4%.
Some good news is that GDR2 has reached 30% of Windows Phones – still slow, but usually the second phase of the roll-out is faster.
The full stats should be available shortly.
