Help Sony Xperia U keeps cutting out during calls.

[elsmandino]

Hi there,

My girlfriend has just bought an Xperia U and it seems fine except for whenever she receives or makes a call, it just randomly hangs up the call and she has to keep ringing back.

Do you any of your guys know whether this is a common problem to this phone generally or whether this is a dud phone?

She is on the GiffGaff network in case this is relevant.

Many thanks

Mine does something similar, when I make a call it says 'calling' for a half minute or so but I don't hear a ringing tone, then it just stops with a ping and returns to the home screen. Sometimes when I answer a call, I get a blank white screen and have to power off and on to clear it. I'm looking for a new phone.
