Advertising network InMobi has compiled the Mobile Insights Report: European Edition, which examines the mobile market for Q3 2011.
The firm claims the iPhone 4 remains the top device in Europe with a 7.2 per cent share, followed by the Samsung GT-i9000 on 4.9 per cent and the HTC Desire S on 3.1 per cent.
Android accounts for 33 per cent of all ads in Europe, more than doubling Apple's iOS on 14.9 per cent, according to the report. Google's OS has seen growth over the past nine months pushing it to become number one in Q3 for the first time.
James Lamberti, VP global research & marketing, InMobi, said: "Consumers have truly embraced mobile and we’ve seen a tremendous spike in mobile usage over the last quarter.
"The significant growth trend that we have measured quarter-on-quarter hasn’t slowed down, highlighting the need to implement effective mobile advertising campaigns, especially in the run up to Christmas."
The report also says that Android will face increased competition with the introduction of iOS5 and the iPhone 4S, although it will be difficult task to catch the firm up.
