We've just gotten some more information regarding the Wifi issues some HTC One X owners have been experiencing, and which the manufacturer acknowledged this morning.
An HTC spokesman tells us that so far only the quad-core Tegra 3 version of the One X appears to be affected; there have been no reports of the issue in the Qualcomm Snapdragon S4. That means if you have the AT&T One X (or any other LTE version), you're likely safe and sound. But it's also worth noting that not we've got a couple Tegra 3 versions that are working just fine. So, again, it's still not known exactly how many phones are affected.
We've also got a little more in the way of instructions for those of you who are experiencing issues.
HTC tells us that if you're seeing this hardware glitch (or even think you are), you should call HTC customer support (you can find your regional phone number here), and they'll help walk you through things to confirm the issue and move on from there. It's also possible you might be able to exchange the phone at the point of purchase, but that can change by country, so we'd start with the customer service call.
