After the recent update:
Google Android 4.3 (Jelly Bean)
14.2.A.1.136
2014-01-30
...my XPERIA Z1 turns the volume up and down automatically on notifications and ringtones, with the equipment on the table, without any touch, sometimes it rings with normal volume and other times it rings on low volume.
I made a restore but the problem still remains, I think the problem is on software, but I don't know if under the definitions menu does exist any option to solve that.
