HTC Sensations suffering from iPhone 4-like "death grip"?
HTC Sensation is currently on a visit to NordicHardware Test lab and waiting to spring around the 20-page article will be ready, we can offer you a brief update, which unfortunately is not a positive one. HTC has gone with a new antenna design in Sensation and in our tests, the phone shows that it suffers from a four iPhone-like "death grip" that lowers the signal strength dramatically.
HTC has with his new superlur Sensation gone with a unibody-style design. My phone's shell is in one piece around the back and squeeze next to the screen and other components in the sides. The similarities to Apple's manufacturing technique does not end here, however, when HTC have also chosen to lead the phone's antenna gain through the cabinet, hoping to improve its signal strength.
The antenna is fed out of the phone's shell (Note: The shell is turned in the opposite direction of the image)
The phone, which generally has a good signal strength suffers, unfortunately, just like the iPhone 4, the problem with dramatically reduced signal strength depending on how to keep his phone in his hand. When Apple introduced its iPhone, 4 telephone arose the concept of "Death Grip" or freely translated into Swedish, the death grip. This when done by cup your hand around your phone could get the signal strength to drop dramatically when the surface-mounted antennas were disturbed by the user's hand.
During our investigations, in which we place on these days could not reach the manufacturer HTC, we have seen that the phone generally lose much signal strength when the entire back is covered with your hands or to keep their fingers on both sides of the phone, which seems to have an antenna to lose composure. Just to put the phone in an open palm can signal that fall sharply.
Normal signal strength when we hold the phone with one hand, significantly reduced (22 dBm) with two fists)
We have seen the effects of the death grip in all wireless communications, WiFi, Bluetooth and 3G. But the biggest problems seems to be the wireless data transmissions as WiFi and Bluetooth. Here we have seen the signal event of between 20-30 dBm when cellular fingers around the back of the phone, which is the worst scenario we've seen.
But just by putting the phone on a flat palm creates major problems for the antenna directly lose plenty of signal strength. Something we quickly caught a bit of video, both when using Bluetooth and WiFi.
Bluetooth streaming immediately affected by the antenna signal. This test is done at 6m distance with two walls, but shows clearly the difference this makes.
We will look for HTC to try to poke further into the problem during the coming week. But clearly, it seems a more difficult task than we thought to develop an external antenna design for our smartphones.
WiFi signal is severely affected, this one meter from the router.
The positive we can say is that "death grip" rarely occurs in normal operation, but in landscape mode, the risk is much greater that you get problems when you will increasingly be in contact with the phone's short sides. For most people should be HTC's antenna design does not cause any major problems, but the problem is there and there's nothing we see signs of the previous phones in class we've tested, including LG and Samsung Optimus 2X S Galaxy II.
We will also add a disclaimer to our test specimens of HTC Sensation may be suffering from an infantile disorder. Why we like to see users who have tried or purchased the phone can load their own experiences and results in the comments or in our smartphone forum .
We'll try to dig a little deeper into this topic in our full-scale review that is expected to be completed next week, which, after all, although there are many other things to talk about when it comes HTC Sensation.
