I have been having some 4G issues so I was taking a look at my signal strength today and noticed that if I cover the top/back of the phone (i.e. over the camera) with my hand the signal drops from about ~90 dBm to ~100 dBm. As soon as I move my hand down goes back to about 90 dBm. FYI, this is happening while I am on 3G not 4G. Are others EVO owners seeing the same drop in signal due to hand placement?
