I am facing a issue as it was 2nd time today morning
My phone goes to silent mode automatically and no vibration and tone buzz when someone calls me, when i tried to change the volume to maximum from option
Settings> sound> volumes> ringtones and notifications(2nd)
It again doesnot change the ringtone sound.
What I did i restarted my phone and then its ringtone working fine for calls and msgs received
THe same problem previously happens before updating to new firmware and still having after updating to new one.
Please suggest me any solution.

First, you can check if there is any app that is causing this problem: task manager, task killer or antivirus app etc.
You can try to do a repair of the phone software and not restore a backup and see if the problem persists:
Click on this link to get Sony PC companion:
Start PC companion, start "Support Zone", start "Update phone software" and click on "Repair".
Follow the on-screen instructions.
Let me know if you are still having this issue after the repair of the phone software.

I found that same issue happening again and again repeating on my sony xperia z. I just need to restart my phone and then same issue disappears.
I dont know the reason why it happens as i observed it anytime automatically switch to silent mode i dont even come to know what changed it to silent mode.
Please suggest something as one more user feels this issue.

Ok I found the problem behind it.
Make sure to close Viber app when you use it. When Viber is activated in the background, and you enter a game or watch a video, the sound switch from the main loudspeaker to the small ear speaker.
Also when calling someone, your ear will drop down the notification menu, activate the bluetooth,or silent your phone, or turn the wifi on, it happened to me many times.
