Default [Q] Some bugs that bothers me

Hi I just recently bought SP (C5303), unlocked BL, rooted, installed CM 11 from here: http://forum.xda-developers.com/show....php?t=2599650 and the phone is great, but I've found some annoying bugs (may be rom issues).

Most important is, that the volume is veeeery low, especially when I'm in noisy places the in-call volume is just not enough even thou I have volume on max. I've found many reports to this problem, but no working solution this (http://www.droidviews.com/get-higher...a-z-zl-t-sp-v/ doesn't seem to do the trick).

Another thing is, when I'm using head set, listening to music and somebody calls me I can't pick it up. Button is working, but it seems to have focus not on dialer, but rather on player widget.

Does anybody else have these issues? Are there any solutions I missed?
