First of all, I am only asking, not saying to stratosk to implement any new functionality. I am not agree with the developer when he add again this feature, but I respect his decision
CM removes this settings by design decisions (again, i am not agree with this decision) and now my calls over bluetooth are very distorsionated. Is very hard to mantain a conversation in free-hands mode. There was a hard discussion about this topic between one cm device mantainer and one person of the cm core team (you can see it in another thread in xda)
Before 4.3 I preserve 2.6.24 kernel version to avoid this distorsion, but now I need to decide to downgrade to 4.2.2 or select another kernel without this feature
About the decision to include this option in semaphore manager or not, i am only making a suggestion, because we have a functionally impossible to manage (at least in cm, i dont know if it is possible with other roms)
Maybe, I will remove them (again) in next version.
