Apple has recaptured its market lead in the US over the Android OS. 
The twelve week period ending in late October sees Apple gaining as much as 48.1 percent of the market while Android fell back to a close 46.7 percent of the market during this period.
The last time Apple held a lead in the US was just after the company launched the previous iPhone called the 4S. It then went on to hold it’s market share for almost three consecutive periods before Android reclaimed it’s market lead again.
The research firm Worldpanel ComTech claims that the iPhone 5’s launch sales helped Apple to regain it market lead over Android, which is at 48.1% of the market compared to its rival’s 46.7%.
Research firm Kantar Worldpanel ComTech also believes that Apple
will hold this lead, maybe even pushing forward a bit and beat its previous high of 49.3 percent on the way to its highest ever share of the US smartphone market.
Outside of the United States Apple does not seem to be as popular. For example in Germany Android accounts for 73.9 percent of sales in Germany and in Spain the OS is even more popular at 81.7 percent. They state that:
“Germany remains a tough market for Apple with its share falling by 5.1 percentage points over the past year. The Samsung Galaxy S3 has taken almost a quarter of the country’s smartphone sales over the past 12 weeks to boost Android yet further.” – Dominic Sunnebo, global consumer insight director at Kantar Worldpanel ComTech
However it is unlikely that Apple will be able to maintain its lead in the US for too long, which due to the fact that many product that run the Android os are usually sold at a much competitive price than Apple products are.
