Hi peeps,

I recently stared having a weird problem with my phone; whenever I make or answer a call the screen goes blank. Even though I remain connected and can continue the conversation, when the call ends I can't do anything, not even switch on/off. The screen stays blank, the buttons don't respond and I have to remove and replace the battery and reboot in order to use it.

If anyone can help me to find a solution I will be most grateful. To give some background; I replaced the entire housing when I smashed the front screen digitiser a few weeks ago it was working fine. I then smashed it again (I know) and replaced just the front screen last week and it started doing this weird behaviour, I had also updated gingerbread a few days before. Finally I reinstalled the OS through the Sony PC Companion but it's still doing it.

PLEASE HELP
