Default THL W200S - Phone freezes while receiving a call

I have a thl w200s I have it for one week and from the time that i first opeened it I face a problem. Almost every 24 hours when receiving a call the phone crashes (freezes) and it doesn't respond to any button (or combination). The only thing i can do is to remove the battery and insert it again. Then the phone restarts automatically. This problem happens almost every 24 hours since i got it. Is anything that i can do to solve this problem?
