Looks like the (hopefully) final release is upon us. I know for some they'd like to see one more beta. But all through the betas I've had one problem twice with Pentastic, which is fixed.
Overall it is buttery smooth, very responsive with nice animations. My only sticking point is that the AOD is not customizable like the lock screen is. That perplexes me bc the AOD is seen all the time when the phone goes idle when AOD is enabled. But one only sees the lock screen for a few seconds.
I'm happy with beta 4 but agree that Samsung should give users the ability to customize aod and not just lock screen, but at least lockstar inside of goodlock will let you do this.
