Did anyone use audio boost? On my 9900 I would get annoyed whenever I saw that icon from accidental activation. With the limited frequency range of phone calls, I never found audio boost (enhanced call audio) a much useful feature. And I have hearing loss in one ear!
I don't know anyone who used it but i did since i listened to a lot of loud music i used this a lot but its not a good thing since its affected my hearing a little only temporally tho like ringing in my ears so im kinda glad its gone... apart from this tho seems the os is much smoother than all previous 7.1 os's 649 for me was pretty rubbish it got very hot and became very uncomfortable for my hands and battery life was awful
