Both Android and iOS increased their share of most markets in the three months to April 2017, according to the latest smartphone OS data from Kantar Worldpanel ComTech.
Samsung's Galaxy S8 did not have a significant impact on sales during the period, and neither did LG's G6, with both ending up outside the top 10 best-selling phones.
“Android partner brands Samsung, LG, and Moto experienced year-on-year declines in the US,” said Lauren Guenveur, global consumer insight director for Kantar Worldpanel.
In the UK, Huawei had significant gains, claiming 8.9% of smartphone sales, a 6.1 percentage increase over the corresponding period a month ago.

"However, the company has historically struggled for share in Great Britain, where Sony and Motorola have been the most popular brands after Apple and Samsung. These latest new figures are the first indications that Huawei is improving its position in Britain.”
In the US, iOS accounted for 36.5% of smartphone sales in the three months to April, a 5.8 percentage point increase over the corresponding period one year earlier.
In urban China, iOS share for the period ending in April dropped year-on-year to 16.2%, or 3.8 percentage points lower than the corresponding period a year ago.
For Apple, this was another period of decline in China that began during the three months ending February 2016.
