My elder brother is using samsung Galaxy Y mobile and it works fine as well. I used it for one month so used my own Google account there but now he wants the phone so I have to return it. Before returning him, I want to remove my Google Account from this mobile. When I tried to do the same, it shows that you will have to wipe up the device. Is there any other method for the same? Actually the problem occurs because my contacts are synchronized with Gmail contacts.
