All Smartphones Are Vulnerable to 'Death Grip,' Study Says

iphoneIt looks like the iPhone 4 isn't the only smartphone that's susceptible to the so-called 'death grip.' A recent study from the University of Bristol found that placing your thumb over any smartphone's antenna can reduce the device's sensitivity by up to 100 fold. The researchers also found that placing a buffer between your thumb and the antenna doesn't mitigate this signal-reducing effect. It should be noted, though, that the iPhone 4 wasn't included in the study -- so there's no reason to throw away those free bumpers just yet.
