Samsung E840 Mobile phone fault

Question

Hi,

I have a Samsung e840 slider phone I have had it for 1 week. I have 2 problems 1) The phone's camera has a fault...when i slide the phone up and push the side button for the camera a message "Please wait" comes on for about 15 seconds then it says "Check camera connection" can you please offer a solution?

2) When i download music onto the phone the phones music and ringtone functions freeze and the only way to get it to run normally again is to delete the music...can you please help?

Thanks very much
SP.
