Well, I don't know anyone knows it or not.. But the current firmwares and kernels for Galaxy S4 are not mature enough to make use of it's legendary hardware set. Firmwares and Kernels are like in beta or pre-release stage. May be they wanted to launch the phone as soon as possible to gain market shares. But I hope (and I am sure) they will release some major firmware upgrade that will fix battery drain issues + the lags they are experiencing so far..

). They will concentrate on performance optimization. Kernel 3.8 and 3.9 sources are already out so they have all the ingredients. What they need is put some manpower and release an update that contains one of these kernels.. It always has been like this I also find icons cartonish but they are much better than what we had with TouchWiz 3.0 and less.Linux Kernel 3.5 onwards have big.Little Support with all major issues sorted out. As far as performance issues and battery life in concerned its partly because of the CPU-hotplug latency due to creation, teardown, and migration of the per-CPU kthreads that carry out housekeeping tasks for various kernel subsystems ( which is something a good scheduler should handle ).
Exactly. The current kernel is based on 3.4.5 which does not really step between both the quads efficiently which cause more battery drain instead. This should be fixed in next patches and I am sure Samsung is working on that. Linux Kernel 3.8 fixes this issue. If developers compile kernels with 3.8+ sources (or Linaro builds) phone will definitely be lag free and more battery efficient.. Being a new processor in market, this is definitely the thing that would have surely happened. They wanted to release the phone earlier because of the competition (Xperia Z and HTC One) hence they released phone with lower level kernel that actually does not support big.little stepping. As far as I know Samsung's strategy, since they have achieved what they wanted (sold like millions of devices
About TouchWiz color thing.. You will find it funny but for Eclair 2.1, Froyo and Gingerbread, they had blue color theme while AOSP had green. After ICS, they changed it to green and AOSP changed color to blue
Maybe it is because CPU is shifting all the cores instead of pairs. I would like to see if somebody comes up with IKS implementation in existing kernel.
Yes, we can activate all the cores in recent kernel versions. But that will be like overkill of cpu resources. We will never need that much power in near future.. But yes, people will still use that feature and do some benchmark showoffsYep, Android 4.3 update should come out a month and half after Google officially releases it, perhaps on June 10th (rumors). Maybe Samsung moves to the newer Linux Kernel 3.8 because that version does support the big.LITTLE design better. There's a HP Max mode which allows all 8 cores to be active for maximum performance (read on Wikipedia), but seeing that the phone has serious heat up issues, doubt that will ever happen.
Didn't know Samsung was playing color dance with AOSP

I am cooking my ROM first, then I will write Android application that will switch in between CPUs when needed. Ideally, well written governor (interactive) should do this job very efficiently. We will never need any app for that after IKS implementation. But just for testing and fun stuff, I am trying my hands on it
Easily doable. In fact, it is in my to do list
