HTC HD7 hit by death grip antenna issue
HTC's HD7 may suffer the same "death grip" issue with its antenna as claimed for the iPhone 4 and other modern smartphones, owners have been finding this weekend. A YouTube poster (below) has shown the T-Mobile version of the phone dropping from four bars to just one after gripping the phone firmly in a natural position. A quick follow-up test from WPCentral (also below) has shown that the signal is low enough to drop calls and bring data to a halt.
The site initially suspected that it was simply an issue with weaker overall reception for T-Mobile, but by mid-video was persuaded that the phone itself was responsible.
Other Windows Phone 7 devices, including the Samsung Focus and the LG Optimus 7, don't appear to be as easily susceptible to the flaw.
All cellphones are at least partly vulnerable to losing their connections through a hand grip, since the water in human hands acts as a natural signal blocker and most phones have their antennas at the bottom to get them away from the user's head. Apple drew extra criticism for this as it made the antenna external and thus more sensitive to anyone bridging the antenna gap, but it has become enough of an issue that phones like the Nokia E71 had issues even with internal designs.
