I just bought Nokia 5233(touch phone). The problem with this phone is that every time i get a call when the phone is locked i get two buttons at the bottom of the screen "answer" and "unlock all" But if i try to press either of them, it doesn't work. A similar thing happens when my phone alarm goes off, I get the two options "stop" and "snooze" but neither of them work. All the other features of the phone are working properly--So, I'm unsure whether there is something wrong with my mobile or if it has something do with the settings...Please reply. Any advice would be highly appreciated and thanks in advance.
