HTC Sensation suffers from death grip, iPhone 4 caught snickering

Looks like there might be trouble in paradise for HTC fans. Nordic Hardware’s tests have proven that the new HTC Sensation also suffers from the same dreaded death grip as the iPhone 4 but this time it also affects the Bluetooth and Wi-Fi connectivity of the phone.
The problematic area is the back cover. The Sensation does not have a true unibody design as HTC claims it does but instead uses a large removable battery cover which is mostly made out of metal and has plastic areas that work as antennas. Unfortunately, when these pieces are covered by your hand, there is a substantial drop in the performance of the radio units within the device, particularly of the Bluetooth and Wi-Fi radios.
