Hi petug thank you for your advice, what annoys me is i am not a big user of android phones, i only use my phone for making calls and texts and i check my emails and talk to a friend, so i only use the Internet about 3 times a week. I am going to go back to buying the Samsung galaxy S range refurbished as i never had a problem with those phones, thank you for advice i will try anything although Samsung tech team have been unable to solve the problem.
