InMobi Sees iOS Falling in Hong Kong, Android Invading [INFOGRAPHIC]

The Infographic of the Day series visually expresses important stories from Asia and the world of technology.

Mobile ad platform InMobi has been busy these past few days crunching ad impressions stats from across Asia, giving us insights into growing smartphone usage in various countries. Now it’s Hong Kong’s turn, where mobile advertising grew 656 percent from Q4 2010 to the same period at the end of 2011. But the picture in Hong Kong is a bleak one for Apple (NASDAQ:AAPL), whose iOS presence in the Chinese SAR fell 16.1 percent; in contrast, Android seemed to grow by a staggering 36.8 percent, and is now the dominant mobile OS in Hong Kong by some margin.

Smartphones as a whole now account for 80 percent of all of InMobi’s observed advertising impressions, squeezing down features-phones – or “advanced phones” as the company calls them – from 38 percent at the end of 2010 down to just 20 percent at the end of 2011.

It’s all in interesting contrast to InMobi’s stats for Vietnam, which we looked at last week – but of course, Hong Kong is a technologically much more advanced market.

There’s also good news for Samsung (005930:KS) in there, as it now has the first- and third-most popular phone in Hong Kong. Here’s the full infographic, which you can click to enlarge:
