Guys, there's something strange happening with my Note 4.

I live in Brazil and here we only received the Lollipop update (BOC3) later last week. For the propose of further questions: I never rooted or modified my phone, It's a SM-N910C.

The thing is, after the update I found some issues with my phone. Same old problems people keep complaining about. My Antutu score droped from 50k to 38k, my Geekbench score was lower too, and performance in general was worse, really worse, perceptibly. I was about to flash the BOC5 ROM from another country 'cause some users claim that this version solves some problems, but them I saw some users with the BOC5 and the same old performance problems. I gave up the flash and while surfing through the settings I found one feature I've never used before, the "Active Knox Protection". It's located between Security options.

After activating that option the system asked me to do a reboot, I did and voila! The performance of my Note 4 was back to what it should always be. My antutu score is again 50k, and the system is faster in general. I thought it might be just a coincidence, but turns out that turning off that option made my phone go back to the "bug" state.

So that's my tip for those who doesn't have root and are facing this GPU bug in lollipop. Would be awesome if you guys could reproduce the procedure and post your results.
