Just days before it is launched across most of the networks in the UK, the HTC Sensation has allegedly been suffering iPhone-like antenna problems.The Nordic Hardware site claims the antenna design used in the new Sensation does make it prone to 'death grip' when the handset is held in a certain way, with the signal strength over Bluetooth, Wi-Fi and mobile dropping dramatically. The site even has videos showing it happen. Not good at all.However, HTC doesn't see it as a problem, primarily because the problem only occurs when you hold it in a less-than-natural way. Speaking to TechRadar, a company spokesperson said: 'No. Every phone experiences a slight variation in signal strength when the antenna is covered in its entirety by a palm or fingers, however under normal circumstances this does not affect the performance of the phone.'So it all depends on how you hold the phone. If a significant number of people hold it that way, it's likely to be a problem. This might be the case when the Vodafone exclusive ends and the rest of the networks are offering the phone. On the flipside, no such problem was found when we reviewed the phone recently - and it was given a thorough going over for the review.
