Hello. I purchased Ideos x1 u8180 (android 2.3.7) from China. It seems to operate normally. However, I cannot find "Play store" "Google store" on a home screen. I referred to the all application list.But Google application did not exist at all. Then I looked the website of Google. And I checked that U8180 was supported by Google. Why isn't google application displayed on my U8180? Please advice me.
