Touchpro Battey Cover creak

[cerchiarax]

Hi Guys,

I'm thinking of heading over to sprint to replace my phone. The phone keeps making this creaking sound coming from the battery cover. When I type or use the touch screen. Is this something I should be expecting because of the cheap cover? Or is it a design flaw with the one I have currently. Let me know your thoughts. I also wanted to note that the phone was build on 10/26 and I bought it at bestbuy.
