Wacom S-Pen sensor layer going bad or defective?

After receiving my new Note 3 a few days ago and setting it up I hadn't even really used the s-pen until yesterday. I noticed that vertically down the middle of the display from top to bottom there is about a 1/4 inch area that the s-pen 'avoids' or 'skips across' when swiping it from side to side. At first I thought maybe it was just the pen tip, so I replaced it. It's hard to explain but the effect I get when hovering it across this area is almost like a magnet avoiding another magnet, it jumps across in front of itself (the dot) and will simply not work properly in this area. Let me try to explain like this: If I were drawing a line on the screen from the bottom left corner to the top right, when I get to this 'magnetic' or 'dead' area the line no longer becomes diagonal but skips up vertically then jumps across to the other side of the dead spot, then lets me continue drawing the diagonal line to the top right corner.. Make sense?

From what I read on howstuff works, the waycom stylus and screens work with some sort of a magnetic field, which would explain why the effect i'm getting is like holding two magnets with same charges they repel, if in fact it's a defective area on the magnetic field under the glass surface.. (Howstuffworks Source)

Is it the wacom layer of the display? I am not using a magnetic case or anything else of the sort. I debated calling T-Mobile and trying to explain this to a customer service rep, and I figure it will be near impossible to get my point across. I am considering just going to the T-Mobile store down the street and trying to get a replacement.

Is anyone else experiencing this phenomenon? Test your screen with the diagonal line test and see for yourself. I'm curious as to this being a rare defect or a more common one. I'm considering putting up a video because it's so weird..

Edit: I have attached a screenshot to display the dead area that the line skips across sideways.. with the action memo, draw something 2 and sketchbook to diagram the avoidance area on the screen

Well I called and explained the problem to the tech support rep. Thankfully they were also an owner of the note 3 and were sympathetic to the issue and understood what I meant. Replacement on the way, hopefully the original post is helpful to others experiencing odd problems with their spen and display..

I'm curious on how you replaced the tip so quickly.

I've disassembled my note 4 and after putting it back together there were two strips on the screen where the spen couldn't write after *#0*# and testing wacom layer it turned out it didn't work (in those two mentioned strips).

Apparently the adhesive (the dumb manufacturing engineers at samsung) used for securing the glass in the frame prevented the gorilla glass from properly aligning on the frame. After I heated up the glass and clamped it to the frame for a few minutes the wacom layer started working again!

Apparently the layer doesn't work/has difficulty working properly when the glass is skewed/not aligned (or sth). Thought I share this in case sb else had a similar issue.

Just for future references, if you go to phone keypad and type *#0*# you will get diagnostic screen with various tests of all the hardware inside, including Viacom test and spen hovering. This may not work with some custom roms.

It didn't work with Dominion rom. Ended up getting fixed with the battery pull I did to get my new SView cover working.

Possible fix

For those who still own a Galaxy Note 3, and have either a GPS issue, or this s-pen issue, (I had both simulataneously) this video (although in another language than English) Galaxy Note 3 SM-N9005 bad GPS Signal SOLVED (can't post vid link because XDA thinks it is potential spam since this is my first comment ever here) is what I did for GPS fix. At the 5:10 mark, or so he is gently levering up those little connectors/stems. They don't make good contact. Earlier in the video he shows how something gets disconnected. That's obvious. On the other side of the phone) is similar connectors/stems. I did the same thing to those.

I put it all back together. GPS works and s-pen dead spots are gone. Also, I blew clean ports and the board with photo air blower. Forgive any wrong terminology.

Hope this helps someone.
