Sony Xperia X miss calls! (was: How to completely disable "Do not disturb" feature?)

[afiskon]

Hello,

I'm using Sony Xperia X (F5121). I noticed that when my phone is in a pocket the sound buttons are acidentally pressed which changes mode from "No sound" to "Do not disturb (Alarm only)". This is very annoying because I miss calls. Also I'm pretty sure that there was no such issue until recent updates (probable there was no DND mode?).

Since I don't use DND at all my question is how to disable it completely? Or at least make the default not "DND (Alarm only)" but "DND (Priority only)"? The last mode has flexible settings wich allow effectively disable DND but unfortunatelly this is not the default mode entered with sound buttons.

20 missed calls today A little piece of advice (or better - a software upgrade) would be MUCH appreciated!

Last option:

Don't put it in your pocket or buy a protective case.
