HTC One X - WIFI antenna loose connection fault.

from the source:
HTC One X (grey HT23) with a loose internal wifi antenna connection. The phone is placed 2 meters (6 feet) from the access point (visible in the background). When I gently squeeze the side back of my phone the signal gets stronger, almost as strong as my comparison, the HTC Desire (seen from 0:18 and forward).

This wifi problem is definitely hardware related and not due to a software bug (as I first though). I have reported the phone DOA (dead on arrival) and I hope HTC will address this issue as soon as possible since it seems to be a common problem. You can read more about this issue here:
