Default [Q] XDA Zest, freezes when clear log

Hi, I have a xda zest O2 phone, when I go into my call history and choose to delete all calls, then I press ok, it freezes on this screen, I need to remove the battery to get the phone back on, and the history is not cleared, even when I try to delete 1 at a time, the same problem.

it is a new phone, I have not updated the firmware.
I am on T-Mobile network, the phone already unlocked.

is there any apps that could be used to clear the call history
as this is very useful for me to clear my logs

Many Thanks.
