I was not having any issues on 4.43 though. KK got me better battery usage and access to new software.
If you are rooted, you can apply the sdcard fix. If you are not rooted, I don't think there it's a fix for that.
Since you are still on 4.3, you can easily root using Kingo or de la vega method without triggering knox.
After that, upgrading to 4.4.2 is very easy and you still have root and warranty.
If you don't care about knox, then you can just update and use Chainfire to root 4.4.2 (knox warranty void). It is pretty simple.
I have 4.4.2, root (from my previous rooted 4.3) and warranty intact + SD fix and xposed mods. The phone is just amazing now.
