[Q] Speaker volume problem after Kitkat update, any fix? topic

The speaker was really working really well before the Kitkat update. I am not 100% sure if that was the cause since the phone was updated shortly after I got it. After the update, every now and then the speaker will become really low volume. Sometimes it can be fixed by restarting the phone, but the problem has been happening more and more often. I have the phone for about a month now.

Is anyone else experiencing this problem? Any suggestion in fixing it? Thank you.
