Android has grown to represent nearly half of smartphones sold in the UK but is no longer gaining ground in the US, Kantar Worldpanel said in a rare gauge of British market share. Google's platform grew 35.1 percent from year to year to reach 44.9 percent of all smartphones sold in the country as of mid-May. Nokia in the meantime saw its own share drop 21.4 percent from year to year to hit 10.6 percent.
