Ad firm's metrics confirm rise of MicroMax, Nexian, K-Touch, Spice and others.
BuzzCity says these localised ‘white box’ manufacturers account for 20 per cent of overall downloads from its free mobile games portal, Djuzz.
Last month, the figure was eight per cent.
Djuzz is designed to deliver games built on Java, Symbian, Windows Mobile, Android, Flash and BlackBerry as well as feature phones at the lower end of the market.
The portal recognises and delivers games for more than 1,800 handsets.
The stats support Gartner figures, which claim that global sales of handsets rose 35 per cent in the third quarter of 2010 to 417million units, and that a third of the devices sold were made by companies that were not among the top five players.
Dr KF Lai, CEO at BuzzCity, said: "’White box’ competition will continue to cannibalise sales from the major manufacturers, largely by mimicking handsets like iPhone or BlackBerry, while offering more features such as multiple SIM capabilities, at lower price points.”
“We believe the game ultimately lies with those who control hardware, software and services and these localized ‘white box’ handsets will soon need to add value with services; users have moved beyond using phones as just a communications tool and the growing priority for consumers is getting more and better content into their phones.
BuzzCity delivered more than 6.5 million games in October, a 12 per cent increase on September.
