z3 signal problem

[phobos]

Hi, 

I have a very strange problem with my new z3. With my vodafone sim I have a very poor reception, my signal is bouncing from 3g to h+ but often with only 1 or 2 bars out of 5. Navigation is almost impossible and often I completely lost connection and I cannot receive also phone calls. I tried with another sim from another operator and I can navigate even if I don't have a good reception ( in comparison with my xperia M, in the same room, I get 5 bars and with the z3 only 1 or 2). The same vodafone sim in other phones works perfectly. It seems like a problem between vodafone operator and the z3 (I've also changed this sim with another one in a vodafone shop porting my phone number but nothing changed) or a reception problem of the phone (this doesn't explain why it works with a sim with another operatore even if with a very poor signal). I don't know what to do...

Thank you for your help!

one of my friend and i having this problem, it keeps iritating us and i almost break my celphone because i cannot get good signal... then my friend bought a pocket router and connect the phone in wifi signal, then it got a good signal... what i suggest you do the same thing, but it the cost of rauter is 650 riyal.. so your total expense is price of phone + price of router.. so expensive...

I'm surprised no-one else has picked up on this. 

This particular problem was observed when I swapped phone system boards on my Z3 due to a hardware issue. 

When I fitted the replacement board, there were issues with the signal, exactly as described on this thread. 

I traced the issue down to an ill fitting antenna cable, the cable would not fit competely onto the socket. 

I eventually managed to get the plug to fit onto the socket on the main board, this resulted in 100% signal restoration. 

On the Z3, this cable is light blue and the socket is a gold colour, you have to be very careful not to force the plug ont othe socket due to its very delicate construction. 

I believe that many phones would have had this problem on the production line fitting due to the badly fitting sockets. 

I hope this helps.

Thanks,

Gary.
