My wife has a Centro, and I have noticed that whenever I talk to her that her voice goes very very very quiet for 15-20 seconds at a time. This may happen only once a call (never on the phone that long to check for it repeating), or sometimes it may not happen at all. All the while she is able to hear me perfectly.

I thought that this could be a problem with my phone or the reception until I talked to someone else for nearly 1hr and never had a problem with their volume. Therefore I must conclude that it is a problem with her Centro.

Has anybody else had this problem?
