Previously we shared a story that the HTC One X might be experiencing a hardware WiFi issue caused when it is held too tightly. Supposedly, it mimics some of the same symptoms of the "Death-grip" issue on one of the previous iPhones, to which Steve Jobs famously said, "You're holding it wrong." This issue with the HTC One X was a bit different however. The problem was that some users experienced improved WiFi when they held the phone too tightly, which suggested an antenna connection problem internally. HTC was alerted to the issue a few weeks ago, and has since responded to the problem with the following statement,

"After investigating isolated reports of WiFi connectivity issues in the HTC One X, we have identified a fix that strengthens the area of the phone around the WiFi antennae connection points. While many customers have not experienced any problems with signal strength, we have taken immediate steps to implement a solution in our production process to prevent this issue from happening in the future. HTC is committed to making sure every customer has a great experience and we apologize for any inconvenience this issue may have caused while we conducted a thorough investigation."
Obviously, this doesn't help us determine how widespread the problem, was, although it's nice to see them own up to it. Also, it does indirectly suggest that it was a small sampling of people who experienced the issue, because they are not issuing any type of recall or repair program. Also, it's important to note, that most of the users who experienced this issue, never really had WiFI connection problems to begin with, so ultimately it's really a non-issue. Still, it's because of our amazing Android community that HTC was made aware of this problem so that they can make sure it doesn't occur in future releases.
