loud speakers not functioning properly

[ket123]

Hello..
I updated my Xperia L to 4.2.2 fee days back.
For the first few days the phone functioned perfectly.But after some days problems such as screen flickering started.
But now the loudspeaker of my Xperia L stop functioning atleast once a day. When I play music sound comes only from the top speaker and not from the bottom speaker. Then when I restart my phone the speakers start functioning properly.
Why does this happen.

Since it starts working properly after a reboot I suspect this could possible be caused by an application. So try running the phone in safe mode for a while and check if this still happens.

In that case I think it needs to fixed at a repair center. Contact your local support team for more information.
