[Galaxy Note 3 Q&A, Help & Troubleshooting] alf69mi:
Hello , to me the problem occurs few times a week so i'm not so concerned.

I am waiting Samsung to release the latest 4.4.2 update for DBT Germany unbranded to see if things improve.

You are ENB4, i am ENB7 now, maybe END3 could help...

I remember when my note3 was out of the box i've got many freezes trying to set it up, then updating the firmware problem lowered.

I also suspect some of the latest Note3 batches could have a hw problem with the multitouch diffrent then the ones reported here, infact if i test the multitouch with the apps suggested here, everything is ok and i get 10 touch points and none disappears with the aligned 3 fingers test...

Who knows ... :(
[Galaxy Note 3 Q&A, Help & Troubleshooting] famicom89:
I don't have the 3 fingers aligned bug nor any issues while testing with 10 touch points too.

I'm italian and was thinking that maybe changing to an italian stock rom with different base could fix this problem, but I don't know if I can do it without tripping knox (heard that EU phones are all region locked) and I've been too busy to do that.

Edit:

Also forgot to mention that the problem was much worse on the first boot, needed to hard-reset via recovery because I could barely use even basic functions.

After that the glitch appears way less, but it's still present. There are no new OTA updates for my model so I haven't tested if changing rom could completeley fix my phone.
[Galaxy Note 3 Q&A, Help & Troubleshooting] WillofWillz:
I just got the multi touch issue or "ghost touches" after updating to the newest firmware on t-mobile. I didn't have any issues before but after updating to NE6, there would be random taps on the screen. It happens often enough that it makes me want to throw my phone out the window.
[Galaxy Note 3 Q&A, Help & Troubleshooting] chispas109:
Wao did you have it on nb4?
[Galaxy Note 3 Q&A, Help & Troubleshooting] WillofWillz:
If it did occur on NB4 it wasn't bad enough that I noticed it. NE6 was really bad where it would just random open apps, scroll through pages and just go crazy. I turned on show touches and there were taps everywhere for a few seconds and then it would stop.

Update: After a day of messing around with it, I have came to the conclusion that the new version of Xposed was causing the random touch issues. Not totally sure why because I don't have any modules loaded. I even had time to write a whole report on my phone without any ghost taps. Re-installed xposed and the ghost taps were appearing again. Going to test it for a few days to see if it actually went away or if it still occurs.

Update: Nevermind. It seems to be a hardware issue. It was going crazy on TWRP recovery randomly clicking on things.

Is there any fix for this issue?
[Galaxy Note 3 Q&A, Help & Troubleshooting] Aizenvalt:
i could use some help as well. anyone has a fix?
[Galaxy Note 3 Q&A, Help & Troubleshooting] columbo:
Sounds like the problem I had, which might not be the same as the one this thread is about. Unfortunately, my experience led me to conclude that it was hardware failure.

I started getting ghost touches shortly after I updated to 4.4.2 (NB7 BTU). Eventually my screen stopped responding to touch input down the middle of the display and the top. I could still use the Spen, but the middle of the screen wouldn't respond to my fingers at all. It has become completely dead except for a 1cm strip on each edge.

I sent it in to Samsung for repair and the screen was replaced. Now I have a new working screen.

I wonder if the board for the digitizer is liable to get damaged due to the device overheating?

Oh, and Knox flag was 0x1. I just made sure to reset the other counters with TriangleAway and then reflash the device with an unrooted official Rom before sending it in.
[Galaxy Note 3 Q&A, Help & Troubleshooting] atlana:
I have tried both touch tester apps mentioned in first post, had my GF help with additional fingers. No ghosting, no disappearance up to/at 10 fingers in either landscape or portrait mode. Only thing I noticed was, if fingers are very tightly close to each other (my GF has very slender fingers) ,it registered both fingers as one - I presume that's normal.

Bought my phone in february. Had a DOA after OTA to 4.4.2 (from 4.3), my carrier had it instantly replaced with a new factory-new device.

Hey guys, I'm about to buy a note 3 n9005 and I found this post.

This is a software problem right? Only with Sammy firmwares?

Sorry for my english.

Thanks in advance.
[Galaxy Note 3 Q&A, Help & Troubleshooting] nicholaschum:
Your English is fine.

It's a software issue. Honestly I never had any problems unlike my OPO. Don't worry about it.
[Galaxy Note 3 Q&A, Help & Troubleshooting] anavias:
I'm experiencing this problem from a T-mobile Galaxy Note 3 that I just purchased (reportedly in mint "like new" condition) off of Swappa.

The phone appears to be updated to the latest firmware. Is there anything else I can do to fix it? It is rather annoying. It even occurs when I'm not touching the screen, which makes it difficult to even enter the PIN at times.

[Galaxy Note 3 Q&A, Help & Troubleshooting] LuMe96:
Same issue here on a N9005 bought In France. Also tested with Devs Options showing touch impact. Same problem so not an issue with Multitouch Tester app. I just hope that this is not a hardware problem but something that can be corrected by software.

Holding 3 fingers still or barely moving = touch points disappear

You start moving a little and even with more fingers this can't be reproduced...

is it really a cause for concern?

anyone know any game which require 3+ touch inputs to test for problems?

Tested on N9005 - XXUBMJ1
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
Besides multi-finger swipe gestures (which at least iOS has) there are many games and such which support steering, looking around, firing and/or aiming simultaneously. Mario Kart was mentioned in one of the first posts here. The problem with any of these, games or otherwise, is that these glitches are seen as deliberate user decisions and cause random behavior ruining the user experience.

Also any defect your phone has can become a problem once you sell your phone to someone who is sensitive to this defect and complaints about it.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Maverick777:
Mine detects 10 as well. Moving around is not an issue unless my fingers get too close together. If my fingers are side by side, sometimes it only registers one touch at that spot. I think it's working just fine.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
Detecting 10 fingers isn't the issue, just like glitches caused by fingers being too close together. Good to hear that your phone is fine though. ;)
[Galaxy Note 3 Q&A, Help & Troubleshooting] terra_droid:
Has there been any official word from Samsung regarding this multi-touch issue on the Note 3?
[Galaxy Note 3 Q&A, Help & Troubleshooting] akns:
Actually, doing this (holding 3 still) reproduces it consistently for me. Perhaps the OP can add that to his directions.

---------- Post added at 06:19 PM ---------- Previous post was at 06:12 PM ----------

The question is has anyone been able to get a repair / replacement by showing them the problem? I could see being turned away by them saying oh that's normal, all touchscreens do that.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Jack Barrett:
Few months ago the new nexus 7 had multi touch issue, that's why new update was released. So it can be fixed with software. Don't freak out. If many people find it should be software related. Im sure all of these samsung sensors work just fine.
[Galaxy Note 3 Q&A, Help & Troubleshooting] kersh:
Yep, following the instructions I have ghosts touchs and problems.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
I have not yet contacted them, I would have but my phone has a set "knox warranty" flag voiding warranty. We are now getting to a stage where enough evidence is gathering to indicate that this is not an isolated incident and Samsung should be notified.

Thanks for your suggestion, I have updated the procedure to make it easier / clearer.

Afaik, the problem on the Nexus 7 was never solved only it was made less noticeable for most people. I still have it on my brand new Nexus 7 with the latest firmware, only not as severe as on my Note 3.
[Galaxy Note 3 Q&A, Help & Troubleshooting] terra_droid:
I still have my 9 month onld Note 2 and tested it in parallel to the Note 3. MTI (Multi Touch Issue) does not appear on the Note 2, but on the Note 3, it does. Maybe it's because the Note 3 has a higher ppi (441 ppi) than the Note 2 (276 ppi)?
[Galaxy Note 3 Q&A, Help & Troubleshooting] Brandersnatcher:
Something to check out...

If you go to developer options and turn on show touches, then go to a multi touch app.. even if the touches dissappear, the "touches" from dev options are still visible.

How can it dissappear, yet still register?
[Galaxy Note 3 Q&A, Help & Troubleshooting] SoreGums:
Use Developer Tools?

Seems it is simpler to use Developer Options?

Settings > General > About > tap on build number 10 times until dev tools are enabled.

Settings > General > About > Developer Options

Scroll down to Input and tick

- Show touches

- Show pointer location

then go crazy :)

If I had more than 10 digits i wonder if it would work.

Also using this options you can see of the pressure of the S Pen works - pretty neat

[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
My current test procedure calls for slight finger movements. Sofar I was unable to see these "Developer" touches' presence or absence under those conditions, because the circles are much smaller than my fingers. What is the procedure you used to circumvent this?
[Galaxy Note 3 Q&A, Help & Troubleshooting] StylusEcho:
Be more specific. How far apart are my fingers supposed to be? If you mean squished together, then yes I can easily reproduce the problem. Then again the same or worse happens on my old S2, though it never posed issues. I'm not sure what to think.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
Nope. Fingers can be half an inch apart (space in between).
[Galaxy Note 3 Q&A, Help & Troubleshooting] LuMe96:
As far as I am concerned, the developer touches behave the same as the circles of the multitouch tester. I do agree that they are hard to spot underneath the fingers but multiple tests make me believe that they also reproduce these issues. Several times I was even able to "produce" ghost finger effects with developer touches shown inside the ghost circles.

I really do hope that this is a driver / software issue that can be AND WILL BE corrected soon as I don't see my local reseller swapping my phone just because of this.

[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
I will try this method too and see if I can draw the same conclusions. As you say, hopefully it is just a software problem that a part of the Note 3 owners experience.

EDIT: Nope, the "developer dots" are moving around just as erratically as the large circles of the MultiTouch test tools that I use.
[Galaxy Note 3 Q&A, Help & Troubleshooting] LuMe96:
It might be interesting to compare software version of those having the issue and those who don't.

For myself I'm running XXUBMI7.

I would try other versions but with this KNOX stuff I'm even scared of flashing official fw with Odin, especially having this issue.

Thanks for the video!

And thanks Action B for showing that it also happens in portrait!

[YOUTUBE]9gQpFZ0PATo[/YOUTUBE]

I also managed to have both fingers disappear this time (in landscape). It is possible that running on batteries or charger has some influence also.

Just trying again for a bit today showed me that it can be hard at times to reproduce the multitouch problem for a 'casual', untrained tester using just two fingers. Using 3 fingers, like I described in my original opening post, could be somewhat easier for them (this method is shown in the first clip). To show that at least -something- is wrong it is MUCH easier to just put 5 fingers on the screen and moving them about at random and see one or more glitch / disappear. This video shows the latter, through an "unwilling" participant:

[Galaxy Note 3 Q&A, Help & Troubleshooting] Mikegrmn:
After reading this thread a couple of days ago, I used multi touch test today because I wanted to know if my N3 could be affected. Seems everything is working fine. I tested to the point where I used 7 fingers. With 7, the app started showing jumping numbers of used fingers, down to 2. but honestly, I'm not sure if my fingers stayed on the screen properly with 7 fingers. Actually, the only time I use more than one finger is pinch to zoom and maybe a game or two. But for games, I wouldn't know why I'd need more than 2 fingers at one time. So if my phone works properly with 2-3 fingers, I'm fine.

I'm autorooted, running wanam and the latest "de-knoxed" firmwareupdate.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
I updated the opening post and procedure. Also included videos. Can you check if you now CAN reproduce this with fewer fingers? Thanks in advance.

Hi everyone !

I have the same issue starting with five fingers in landscape (ghosts and disappearing rounds). European SM N9005 from France already rooted and under Omega v2.1.
[Galaxy Note 3 Q&A, Help & Troubleshooting] hardahmed:
Tested with 2 fingers and 3 fingers. The problem is confirmed. I was able to get both points disappear. Glitch happens only when you slowly move your fingers, fast pace moving fingers does'nt affect the response or cause an issue. Im sure it is a software issue, at least thats what im hoping for since mine is already rooted.

Hi

I tested this to and I could replicate the issue on my unrooted original N-9005.

Then I turned off enhance touchscreen option (for use with gloves) and rebooted and problem gone.

Does anyone with problems have this option enabled?
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
I just tried both, as I had never switched the extra sensitivity to ON. Unfortunately it made no difference.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Mikegrmn:
I can't get this issue with only 2 fingers. With 3 I got random numbers from what seemed to be when all 3 fingers were in one line. But it went back to normal in most cases when I moved one finger away from that line. But it was kinda hard to replicate. So Me thinks this won't be an issue for me in regular use. Maybe this also happens on other devices and it's not even a bug? I mean the screen has to somehow calculate the coordinates of each finger and when all fingers are in one line, one coordinate is the same for all fingers. Maybe this confuses the algorithm used which determines how many fingers are used and where each finger is on the screen? I'll test on my razr HD and report back.

Just tried on my razr HD. I can't replicate the missing fingers when having 3 finters on one line. But I found that 3 goes down to one when my fingers are touching each other close to the point where the fingertips touch the screen. But you need some threashhold for the capacity and this changes when the fingers touch each other, so this seems to be expected. I know that capacitive touch may have problems with wet and too dry. My fingers are usually a bit sweaty, so maybe it's just the right amount.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Ettepetje:
Many people will never notice any defect, I am sure, but you very well could get glitchy (and annoying / disastrous) behavior at some point. Every "glitch" is interpreted as a separate event making your Note 3 or App think you want it to do something. With several fingers needed, in landscape only, this would irl only be problematic during some games. Now knowing it can happen with just 2 fingers in portrait AND landscape, just because your fingers are at the same screen height, these glitches will prove to be far more common. Also, while you might not mind too much it could very well be that if this isn't sufficiently solved by Samsung a new owner of your phone is less forgiving. Edit: If this is after the warranty expired he might return it to you or demand a discount.

Let's hope for the best! It could very well turn out to be an issue in some firmware versions only. ;)
[Galaxy Note 3 Q&A, Help & Troubleshooting] Action B:
I agree with this. I had a progressive digitizer problem on my evo 3d. First it was barely noticeable and later phantom touches became so bad that I had to replace the digitizer. I personally would feel better about my note 3 purchase if it didn't do it at all.
