i tryed it with pc companion does it make a difference because the repair with pc companion doesn't work it still keeps freezing

[Uliwooly]

it should be the same, I think it's an app acting up, perhaps a taskiller, antivirus or battery app, repair your phone and do NOT download any app at all, uninstall mcafee and see if you get the same error

i use a task killer and a battery app can those applications make the phone freeze or cause the screen to be unresponsive?

[Uliwooly]

yes they can

you do NOT need them at all

Android apps that use power control APIs are often 'battery killers,' oh the irony
