I have a Sony expira C4 with a little problem.

The phone is grate but the signal is a bit of a problem, I have to twist or bend the phone to get signal back when it's drops out.

So my guess is that there is a loose connection on the logic board but I don't really know where to start looking.

I've tried replacing the antenna but I'm still having the same problem.

I'm hoping that there may be a solder joint fail some where, so I can just make good on the connection and not have to reflow the hole board.

Any help and advice would be great thanks.
