Hello. I am in trouble about U8180(android 2.3.7) imported from China. The Google application is not installed in these U8180 at all. Therefore, I installed "Google Store" by APK file. Install was finished normally. And I tried to use Google Store. Then, dialog box was displayed.I had to input google account. And I tapped ok buton at dialog box. Then, the screen has returned to the home. I tried several times. However, the result was the same. Would you advise me on the evasion measure?
