It hangs at "aufsliden" black on screen.
Sometimes the display does not jump an.Die Home button is broken (which leads the if you want to terminate an application that needs to switch off mobile phone because there is no other way to return), it takes forever (ie hours) to load content (MP3, SMS, phonebook ...)
