Update 3: The battery drain and distorted sound when doing video recording is still there.... Very stable though.. So I will keep it as my daily driver.
Update 2: In the 20130901 Nightly Build should apparently both the battery drain and the audio bugs be fixed! That sounds awesome, installing it as we speak :) Will use it as my daily driver the coming work week, to see how good it is.
Update: This nightly build is very stable, I still haven't found any bugs, the camera works perfectly (haven't tried video recording yet though), GPS works, WiFi works great, no connection issues, Battery life is not the greatest but much better than with CM 10.1 RC. I will actually use this as my daily driver now. It will be interesting to see if the audio recording is fixed too. I will found out next time I do a vlog.
So, now i am back again on CyanogenMod 10.2 nightly on my Samsung Galaxy S3 4G (GT-i9305). The CM 10.1 Release Candidate worked very well, no huge bugs, except for draining the battery fast… Probably some kind of Deep Sleep bug, but after reading the Cyanogen forums, I saw that the latest CM 10.2 20130830 Nightly Build had finally fixed the very annoying graphic glitch that made the screen flash in black, I decided to try that out, because you know me, I want to try the latest, and definitely want Android 4.3, so I restored my Rom manager backup I had of CM 10.2, and then used the CM updater in settings to install the latest Nightly. So here I am on CM 10.2 again, and the black flashing display bug is fixed. Great!
And if I regret it, it's very easy to go back to CM 10.1 RC again, I just restore the Rom Manager backup I did of it ;)
I will let you know if I find any huge bugs.
