Phone [Q] Note 2 AOSP and CM issues - call recording and high mic gain on camera

Hi Guys,

I am getting sick and tired from my samsung based rom on my Note 2.
Every samsung based rom I use is becoming unacceptably slow and sluggish after some weeks of use and I would like to give another try to a CM or AOSP based rom.

Now the last time I tried that - I was having two main issues which made me to go back to samsung:
1. Video camera Mic gain - the Mic gain when shooting video was very high and that messed up every video I took, especially when filmeing in a loud environment.
2. Call recording - couldn't find a decent call recorder - on samsung I just need to enable it using Xposed and it works flawlessly.

Are those known issues when using custom roms on Note 2 devices?
Can you tell me if there's a solution for those so I can finally use my phone properly?

Thanks in advance!
