My phone is Kyrocera Hydro Icon, with Android 4.4.2. I am in US and using Sprint network.
When I am in my apartment, google map will automatically log into my google account, no matter whether my phone is using mobile service or wifi.
When I am away from my apartment and my phone is using mobile data service, google map app will say that something link "can't sign in using my google account". The result of that is I can't retrieve the history of places which I have looked up, and I can't access the places which I have saved.
Why is the problem, and how can I solve it?
