Hi all ......my first post on the forum nice to read you all ......... Interesting thing....... I have had the Hero for a couple of weeks but I am not that impressed with the signal strength. I have noticed one thing though .... I can have, say one or two bars showing and then I dial the speaking clock or whatever if i watch the bars they will usually start increasing up to full signal sometimes, sometimes after I have stopped the call they can increase for a short time. A few seconds after I have ended the call they revert back to one or two bars. Does anyone elses Hero do this?
