Statcounter is not really a serious source for market share.
Both Counterpoint Research and Strategy Analytics give Apple a more credible 20% market share in Europe behind Samsung and Xiaomi.
It's not disastrous but it compares poorly to the between 55% and 65% of the USA market.
Well, it is a domestic product there (at least the HQ is US). Also, Eastern Europe probably worsens the percentages a bit because it is ridiculously expensive for us (like, there was a statistic recently on how many days one would have to work to buy the latest iphone and it was quite tragic from our perspective with something like more than 2 months worth of salary, while it is a few days in other countries)
