Speakers problem

[davood]

Hi

I had to translate text with Google Translate .

About a month that bought a Sony L.

And software upgrade to Android 4.2.2 , and done all the updates .

The problem which then calls up the sound from the main speaker ( back cover ) were cut and transferred to the left front

speaker, the sound was very little .

And the phone ringing and no longer affects the sound .

Currently the only way to resolve this problem is to restart the phone .

I had this problem on several sites , I heard several people in the pot .

Please help me to resolve this problem

That sounds quite strange. Try to see if you experience the same behavior if you start your phone in safe mode:

Dear Sir,

      i have this problem too same week after installing the same buggy update , this problem appears after a while of turning on the phone ( 2 or 3 days may be ) and once i restart the phone  in the normal mode it disappears for a similar period and so on.

so once i restart the phone in the safe mode the problem will disapppear too, so i don't know what this can prove.

If run the phone in safe mode for a couple of hours without experience the same behavior it seems like it may be caused by some 3rd party application in your phone. 

If the behavior comes back when in safe mode I would suggest that you try to reinstall/repair the phone software using PC Companion:

In PC Companion, press start on Support Zone > Start on Update the phones software > "Repair phone".
