This is my first android device. I am as noobish as they come. Just got off the phone with Coby tech support. They couldn't help me, so I come to you guys. Ever since my tablet arrived in the mail today, it won't keep running. It randomly locks up, then shuts down. There is also a small crackling sound coming out of one of the speakers when there is nothing playing. Have any of you encountered these problems? If so, what solutions have you come up with? I'm afraid I am going to have to return this to Adorama for an exchange and their shipping is sloooow!
