Screen issues - Galaxy Note 3 Q&A, Help & Troubleshooting

I have this kind of problem with the screen. Sometimes when I leave the scren and for example read something on the web some little tiny colorful spots appear on some points. But when I move (touch the screen) they disappear. Does anyone have this problem too?

XDA Mini (Wizard Screen Issue)

My XDA Mini has a screen issue.
Only part for the screen (the middle) has stopped responding to the touch pad.
How do I fix this, has anyone else had it?
Cheers
Max
My Wizard (O2 XDA Mini S) has just developed this problem. The touch screen does not respond to touches around the middle of the screen. The outside edges of the screen work fine however.
I've had it for about 4 years now though, so I suppose its lasted well really. It's a G4 and I installed a WM6.1 ROM on it about 6 months ago (which is awesome btw, makes the phone sooo much better / faster!) but I don't think this is related to the problem.
Any known fix for this? I think it's a hardware issue since I also have the problem where upon opening/closing the keyboard, the screen goes white with multicoloured vertical lines and the phone emits a high pitched noise (have to put phone into standby then wake it up again to resolve). This, whilst annoying, I can live with, but not now the middle of the screen no longer responds to touches
I read somewhere its to do with the ribbon cable that connects the screen and main board, its gets trapped or worn over time as the keyboard is slid in and out. So I guess the touch problem is a more severe symptom of this? Can it be fixed?
Also a point of interest is that I keep the phone in the case a lot of the time. Could the magnets have possibly affected the screen? Anyone else with this problem keep the phone in its case a lot?
Thanks in advance,

bug of the stylus to s memo

do anyone of you notice this bug...
1) when the phone is placed on table flat(with screen facing up), there is nothing wrong...
2) when the phone is place upside down (with screen facing down, when you have the phone on bed and over your head), then without having the stylus pen actual touches the screen, the screen senses it and leave a mark.
it even can activate any icon...
is this me only or general bug?
It effects all Notes. Its a known issue with this digitizer.
Basically touch is registered without pen actually touching the screen when you are using it laying on bed where screen is facing down. It registers from about 3-4 millimetres away.
I'm trying this right now as I post this and I can't seem to replicate the issue...

Touchscreen bug? Left / right edge sensitivity shot

Ok, so I use SwipePad and PA's pie to swipe from the left and right edges of the screen. Now randomly I can't do that anymore because for some reason the touch sensitivity just broke(?) when swiping from the left and right edges. This happened on my old Nexus too. Now I'm forced to rearrange where I have my swipe points. Has anyone else come across this problem of not being able to swipe from the edges?
Edit: Problem was related to Touch Control creating dead zones on the edges.

How did you solve the problem. I've got the same issue, but can't solve it just knowing its the TouchControl.
Thanks in advance

[Q] help with sensitive screens

Please can anyone help me since I moved to Note3 (from a Note1) I now suffer from a problem that I never had before and that is when I touch an icon to open an app instead of opening the app the screen flicks to the next page(screen).
If I am very positive in touching the app icon this does not happen, but I never had to be so positive with Note1 switching from screen to screen required a bit more than a little wobble on an icon.
Is there a way I can reduce the sensitivity of this screen switching?
Thanks
Sam

Squares make touch screen unresponsive..

Yep. squares, allot of them.
i had this issue since day one with kitkat, lollipop didn't help.
i can't view or edit .doc or .pdf if it has squares on it, also some website's. Just watching a picture with squares (like in attachment) make it lag or unresponsive until i turnoff the screen and then rotate it, whene i rotate the phone the issue will disappear.
Worth noting that on sun light i can see vertical lines of the digitizer. like in this thread
http://forum.xda-developers.com/showthread.php?t=2590622
My theory is that when the squares line up with the digitizer lines it make it unresponsive...
also the same issue as this video, it's a very rare issue whene the screen is unresponsive on the top right if it's flat on a table. but when i touch it anywhere it becomes responsive again

if anyone have the same issue, or can help me solve mine, is welcomed with his suggestion.
