Few days back, when a leaked Android 4.3 build (JWR66N) for the Google Edition Galaxy S4 (GT-I9505) hit the web, XDA recognized developer Chainfire released SuperSU v1.41 for those who wished to have a root. Later, the same root method was successfully tested on Android 4.3 running on Nexus 4 and we put up a tutorial on how to use it.

If you have already used SuperSU v1.41 to root your device, then probably you might have experienced trouble with the CPU spike bug which is caused when some rooted apps close the SU secession in different and anticipated ways. Chainfire has now fixed this bug through an update (version 1.43). SuperSU v1.43 offers a temporary solution to the bug which causes the CPU usage rise up to 100%.

Even if you haven’t had any problems yet, it’ll always be better to jump onto a smoother version. So go ahead and update it via Play Store or flash the zip file given here manually via a custom recovery (BONUS TIP : What Is A Custom Recovery? [Explained]).
