I adore Samsungs line of smartphones, I loved my Galaxy S and I loved my Galaxy Note, I also love the look of the Galaxy S III and the latest addition The Galaxy S IV. The only thing that I’m not a big fan of is TouchWiz. TouchWiz is Samsung’s default homescreen/launcher across all of their smartphones and tablets and it’s often bulky and not very custom friendly, I’ll often find myself downloading Apex Launcher because it closely resembles Vanilla Android – the homescreen/launcher you’d find on Google’s Flagship Nexus devices.
The only problem with this is that Apex Launcher isn’t 100% stable and when an update is installed you’ll find that you have to set it as the default launcher again. It’s not too much of a problem but can be a little annoying. If you’re feeling adventurous though you could root and flash your Samsung device with CyanogenMod. CyanogenMod is a ROM that closely resembled Vanilla Android but with a few performance tweaks. It’s one of the most popular ROM for Samsung devices or any Android device for that matter but recently development for CM has petered out a little and that’s due to difficulties with modding Samsung’s latest devices.
In a thread on XDA XpLoDWilD spoken out on behalf of Team Hacksung:
Nobody at Team Hacksung (the team behind Galaxy S2, Note, S3, Note2, G Tabs… official CM ports) plans to buy it, neither develop for it. There are two variants which will be a pain to maintain, [and] the bugs we have on the S3 will probably be there on S4, too (camera), and we all know Samsung ability to release sources while staying in line with mainline. Yes Qualcomm releases sources, but Exynos sources we had were far from [working on] actual Galaxy products. I’m pretty sure the same will happen for this one.
That’s a uniform “no” from us.
The Android Central post goes into it into a little more details, but the basic gist of it is that Samsung have been making it increasingly difficult for CM developers to access the bits that they need to create a stable build of CM and with the Galaxy S IV having two variants with two completely different processors and in turn two completely different firmware builds it’ll be come a real pain to maintain and build the ROM.
