solo220 wroteThe sensation has the grip of death, if you hold it with your palm around it the WiFi signal will weaken , but using rubber covers the effect is minimal, maybe the same is happening with the ONE .
i don't have ONE but if the antenna is integrated with the battery cover like the sensation than it's the same problem.
although with my sensation the effect never happened.
Actually with the One X it's a reverse death grip.
The signal would be low to dead until you squeeze the phone in a specific location.
Check the xda-developers link in my initial post for info and videos.
I am not sure how spread this is and it stops me from buying one from Amhaz, due to lack of warranty.
