Xperia L speaker problem

[annkiit]

Hi all , i have just purchased an Xperia L yesterday for my dad. The loudspeaker is working fine whenever I try to play songs. However, whenever I make a call on loudspeaker(incoming/outgoing) it continuously makes a squeaking noise that you generally hear when somebody speaks on the mike and there is echo as well. I restarted the phone but the problem persists. Please help

Hi, this is a known problem with the latest firmware. I think they are going to release a new firmware fixing it soon.
