Gday, My Galaxy S has as of today stuffed up. the issues are as follows, 1. the menu button on the left hand side will when pressed show up for a second, then it will disapear and i cant use it. 2. the back key on the right hand side works, however i think it is stuffing up apps, when i open an app it will automaticly close, or stay open and close after a few seconds. 3. finally my phone is locked and contiusly flashed the display screen even when it is locked. I have tryed taking out the battery and letting it sit but yer any help or advise, this is my second galaxy S in less then 6 months.
