I've had my sensation 3-4 months now and its been great but a few days ago the camera stopped working, i've tried resarting, removing battery for 1/2 hour and even a factory restore but nothing has got the camera working again its as though the drivers are lost screen goes black with camera icon in middle then goes back to menu screen, but after a restart i get the message 'The Application talk (process com. google. android. talk) has stopped unexpectedly. please try again' with the option to 'force close'
