after update incoming calls not ringing

after dirty flash pre rooted .368 zip on 6903 incoming calls are just vibrate not ringing. any solution?

No vibration when ringing.

Even though its set to vibrate, it doesn't. Nothing when on ring mode, or vibrate mode.

Other vibrations work fine, just not when ringing.

Anyone else?

Increase ringing volume without root

I know maybe my question is repeated very often But I search a lot before posting this thread...
Xperia Z3 and Z2 has low ringing volume compared to the loudspeakers abilities..
with root the problem is solved by flashing a sound mod.. But I'm looking for a solution without root
maybe for an app.. for example in Galaxy devices have ascending ringtone problem... and there is an app called "Disable Increasing Ring" to fix it without root

maybe there is a similar solution for low ringtone volume in Xperia devices... I hope so
any solution???
