I had this on my S3, It has nothing to do with the update. This indicates a display problem and the purple smear will continue to grow. From my experience with my S3, your screen will start to have purple spots all over within the next day or two and eventually the whole screen turns darkish purple and fails.

What I understand from this issue is it seems to be related to humidity making it's way into the screen ultimately causing the failure. Typically it starts from where there's significant amount of heat being generated. On my S3, it starts at the bottom left, which is where the Exynos CPU is. There is a thermal patch that sits on top of the Exynos CPU and subsequently transferring the heat to the screen, ultimately causing it to fail. The bit marked in Orange below contacts the screen via a thermal patch:



Seems like a common problem and sad to see it's still occurring on the Note 3. Strangely enough yours occurred at a location where there's no significant heat source other than the charger circuit.

+1 on that.

Mine's 9 hours on battery and battery is still at 83% with the Gear connected all the time and tons of mail coming in via IMAP on K-9 Mail. Seems like with clearing the junk and with last night's update, very little time is spent awake.

I disabled the Samsung Push Service on top of what I earlier disabled. For those who don't use Samsung stuff like ChatOn, you can disable this service. Apparently a well known battery hog.

An on another note, the gear is awesome and enjoying it here. From 9am till now, the battery is still at 81% with some tinkering with the camera, notifications, receiving/making calls.
