[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Kizune:
Well, actually the method shown in the video is the "previous version" of the current one. I could produce the bug with that method very often right after booting. But the "whole hand" method is more reliable.

1. When taking notes at the university, I sometimes move the viewport in S Note using the zoom gesture without the zooming motion. And as you can see, putting my hand on the screen as shown in the video triggers the problem for me, so doing that gesture is almost impossible for me. I know there are scrollbars, but they move the viewport too slowly (but of course I use them when I notice the multitouch issues are occurring).

2. Same as above, but when drawing in Sketchbook or ArtFlow. And here it's extremely annoying because there are no scrollbars I could use.

3. A small annoyance compared to the others but: When I play Carmageddon, the multitouch issues get triggered once in a while. And then I can only either control the car, or accelerate or break, but not both simultaneously. Sometimes my touches aren't even registered at all. I often get destroyed due to the multitouch issues. :rolleyes:
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
I changed the description in the opening post. I never had it happen like that yet. Did you know you get the errors just by holding the side of your hand on the screen for a bit? I thought that was how you discovered this. Doing that looks very similar to how you are holding your hand in the videoclip.

Did you find another way to get rid of the issues besides resetting your Note?

Btw: With Carmageddon, if you are high enough level and want to kill pedestrians, not having control means your opponents die crashing into you, ending the race before you finish all pedestrians.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Kizune:
Exactly, I noticed it while taking notes. And then I made this my test method to replicate the error. ;)

Anyway, here are some videos. The first shows a real-life situation in S Note with that problem, the second and third show that the problem also occurs in other multitouch test apps (yes, I'm looking at you, atg284 ;)).

And to make it more "real-world friendly", I used my old "provocation method" because that's how you put your hand on the screen while drawing and writing.

Yup. And I even got that tank-like bonus police car, so they die just by touching my car tank. :D

I do stand corrected I can reproduce this issue on the new Note, old Note is fine and dandy.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
Did it take longer to get the erratic behavior like you said in pm? I'm trying to get the description in the opening post right, since we got 4 people now who claim they don't have it. I think the score should be 100%, and just included the Poll so that people at Samsung would quickly realise how big the impact is.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] chadiz:
I can duplicate this.. just didn't figure how to repeat consistently until now..

First noticed when trying to pinch zoom in adobe reader .. you get very jerky redraw back and forth.. this could be app specific , but i haven't seen this on other devices
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Romokos:
I'm also experiencing this. It's a terrible issue when taking notes in class.

Can we expect a fix?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
If enough people bother to check if they have this issue (very probably most / all do have it) and fill in the poll. Then all that is left is someone from Samsung or one of its Service Centers to see this, check their own 2014 Note 10.1 and get this through to their headquarters.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] ChrisNee1988:
I have this issue as well, hope we get a quick fix. Did the original note have this at any point in time?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
No. Several owners tried their older model tablet for this.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
Very strange that on such a pen oriented device so few people seem to bother with this Multitouch issue. If you are drawing and/or taking notes and have pinch zoom enabled all hell breaks loose whenever you put your hand on the screen to start drawing or taking notes.

As this is a software issue and I have had this issue on all Samsung updates so far (didn't get the third one though), everyone should have this issue, unless Samsung uses different touch sensitive layers for different models/markets with different drivers/protocols.

Mine is a Wifi model with Exynos, and SUPER clearly has these issues when following the written procedure in the opening post.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] ckelly33:
I tried this using an app called "Multi-touch test" and I don't seem to have the issue. I have received the third update though. Maybe that is it (though I've never noticed it before either).
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
Did you hold (at least) a sizeable part of your hand on the tablet screen for several seconds, while in the Multitouch Test app, and shortly after that (within a few seconds) put one or more fingers on the screen? I usually start out with one or two fingers on the screen, add or remove a couple while moving them around half an inch or so. In my case it then detects one, none, two, or any number of touches in one big mess. Ghost-touches, not anywhere close to where your fingers are (or were). Sometimes having a couple of fingers on the screen, withdrawing them and still see them remembered on the screen, like you never removed them.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] ckelly33:
Yes. I did just like the instructions said. Probably three times. When I put my hand down it detects about 20 (no I didn't really count). I kept it there 3-5 seconds and then went back to 2-3 fingers. No hiccups at all. Maybe it depends on the multi touch app?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
No, just tried (again) on my 2014 Note 10.1. MultiTouch Test is a good app to test the multitouch issue since it already glitches when you have your hand on the screen. I get a list of 7 or so initial detected touches. If I keep my hand on the screen for a while (2-3 seconds) the list all of a sudden clears, becomes a list of 2 etc. etc. just by keeping my hand on the screen.

So, if you couldn't repeat it your software or hardware (or hand, lol, jk) is different. Which software version are you on? (I'm on BMJ6 = second update) Is it a US Wifi model? Mine is a European Wifi (Exynos) unbranded version.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] ckelly33:
U.S. Wi-Fi. Mk1. Third update. Not rooted....yet.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] madsquabbles:
i've taken the 3rd and refreshed back to stock. the issue isn't resolved.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Pippowicz:
I got that issue, too. I found out about that Issue when setting up VPN and got forced to set up a secure Lockscreen.

I chose Pattern Lock and it seemed that unlocking is difficult because the touchscreen looses "focus" to the pattern,

breaking the painting of the pattern. It would be nice to know if this Issue is Software or Hardware related.

I hope that Issue does get solved in the near future.

Still have jumpy multi touch

Anyone make any progress in resolving this issue? I notice it in every app. Usually it's when I hold a finger on the screen without moving it. The screen jumps about randomly. Also, when placing 2 fingers on the screen, it randomly zooms in and out. Is this normal? This is my first Android device, so perhaps I just need to work around this? I also noticed this issue on a floor model at a local Best Buy, so I've never considered exchanging it. I don't get this problem while using the Spen either. I've always hoped future updates would resolve this, but no luck thus far. Thanks in advance.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
I asked a few days ago in the "CleanROM" developer topic (topic was cleaned up since), but the problem seems to be still present in firmware MK1.

For some reason there has been very little exposure to this Multi-touch problem, as far as I am aware. The problem is a real nuisance for anyone who comes across it, but my guess is most people use the device in a way that it seldom occurs. It is also possible that there are differences in touch-related hardware between devices and that only some have this (what I would call) "bad software driver"-problem.

Before this topic I started a similar "Multi-touch issue" topic on the Note 3, where many people attended and which was largely/completely solved by Samsung. Because many custom Kernels and ROMs are partly based on older software versions (for which source code has been published by Samsung) it is still a bit unclear if all problems for that device have been fixed.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] jaytee23:
I have a problem in racing games such as Mini-Motor, Asphalt 7 and others where if I use an on-screen gas-pedal for manual thottle control, it disengages all by itself after some random time period and can be difficult to re-engage even if you re-press the area. It is very annoying and it has forced me to use automatic throttle in all the racing games I have. It sounds like the same exact problem. I'm glad that its not only me!

---------- Post added at 08:49 AM ---------- Previous post was at 08:36 AM ----------

It will occur and is easliy reproduced if you use a manual on-screen throttle (gas pedal) in Mini Motor Racing, Asphalt 7 and Riptide GP. But I have a feeling it will happen in any racing game when using a manual on-screen throttle. And that sucks because the Note plays those games very well except for the manual throttle issue.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Ettepetje:
Oh, I do have this issue clearly, but seeing from the lack of response on this forum few others seem to have it, or seem to have noticed/identified it (or care). It has me puzzled.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] jaytee23:
Honestly, if it wasn't for the problem showing up in specific types of games, I don't know that I would have noticed/identified it either. I haven't seen it anywhere else... yet.

I'm running full stock MJ6

Yes, i reproduced the glitch every time i tried.

WTF is Samsung doing? Charging such a premium price for a device with so much faults. Wake up lag, overall underwhelming performance. And now that? They should put a far more polished product on the market. I'm really pissed off, already waiting for a new tablet, the one I bought had some dead pixels. Really thinking to return the device and switch back to my note 8 (it's not perfect but is far more polished).

Really sad... all those small annoyances. The device has such a potential.

i get this issue randomly in MC4 and FIFA14 in multitouch testers too

this lag starts when i update my note 10.1 2014 32gb 3g p601 to firmware UBMJB

i reset factory my note the problem solved just for 3 or 4 hour when i starting play games like mc4 or fifa14 problems cameback

my smartphone is note 3 P900 and touches works like a charm but 10.1 killing me like a charm i hate this issue

i hope this issue depends on software not hardware
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] lecorbusier:
Can be caused by high cpu load. I experience this often on my dualcore phone, where it's difficult to enter the sim pin and then draw the pattern, while the thing still boots. In that case you could wait, however.

An app running amok could be the culprit in other situations.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] crimpshrine42:
I confirmed when testing Mini Motor Racing that there seems to be issues related to multi touch. Either the steering goes wrong or the gas or a combination of both. It seems to be related to touching both to steer and apply gas at the same time.

I confirmed the same game works fine without the touch issues on another non note based android tablet here. It bothers me that this was reported so many months ago and it does not look like there is any fix.

Is there any chance it is just some of these games? When I use the multi touch testing apps and press one finger on the left hand side of the screen (lower corner) and one on the right in the lower hand corner and leave them like that (for up to a minute I have tried) it registers the touch for both without any issues. So that is what makes me wonder if Mini Motor Racing is just buggy on this tablet.

Edit:

I confirmed I can reproduce oddities with multi touch with at least 2 of the multi touch apps. Maybe not identical to the video, but not good..

One of them if I set my hand on the tablet and sit there eventually (after like 10 seconds) it starts to flash and then if I try the above with using 1 finger on one side, and one on the other, it forgets I am touching it after a few seconds and says please touch me. -- This is with YAMTT

I just tried with multi touch test, and I can reproduce the same thing.

That sucks, not that I play allot of games on my tablet, but if anything comes down the road that requires multi touch to work and Samsung has not fixed this issue in months, I don't have much faith they will.

Dial?

I would hope that there was a way to calibrate this thing, but those instructions sound like they're for another type of device. A phone, perhaps? Am I missing something? Is there a dialer hidden somewhere on the Note 10.1 2014?

Thanks for the link!

My 2012 Note 10.1 has no such issues, tested that when I started the topic.

Also there is no pressure sensitivity that causes the 2014 Note 10.1's Multi-touch issues, at least not with my Wifi European P600. Just lightly placing my hand on the screen for several seconds is enough to produce this phenomenon. Still think it is software related, unless it is caused by build up of electron charge through capacitance (doubtful).

A pitty so little development is being done, by Samsung and by others. I am waiting for 4.4 to come out as there has been no official update for 2.5 months in my region and MK1 reportedly doesn't fix it.

Nope. It's not as visually obvious within other apps, but it seems like any app that uses multi-touch gets confused about exactly where your fingers are at. It's especially noticeable when I hold 2 fingers on the screen as if I was about to zoom in or out. The screen gets all jittery and makes random movements. This happens in any app that uses multi-touch for me. Just an update, I'm likely going to be sending this tablet in to Samsung for a repair over this issue. I submitted the service request along with a video of the problem and a link to this very thread. I guess I need to wait to hear back from them before sending it in, although the information i need to mail it to them has already been generated. Problem is, I noticed this issue on a floor model as well, plus numerous people here are experiencing this. The only solution they have may be to just replace the thing. Fingers crossed!
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] anthropoidape:
Guys, I am trying to see if I have this issue... just trying to make sure I dont' have hardware issues that would require me sending my 10.1-2014 back.

I can kinda sorta reproduce it. I rest my whole hand on the screen while running multitouch test, then take it off. For a few seconds after, it doesn't cope well with 4+ fingers on the screen. However if I leave it alone for a few seconds after removing my whole hand, it acts normally again. If I go out of the test app and back in, it is normal again. No reboots or anything required.

I am thinking that if I have any MT issue at all, it's not a hardware one. Any thoughts?

BTW I am running the Taiwan ML1 firmware.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] haterbait:
Same with me. Multi touch test will work fine once I restart the app, but it will always revert back to that sporadic, jumpy mess that can't determine which finger is where. I imagine this happening within apps and being the cause of the jittery motions that happen when I hold one or more fingers on the screen at a time. In drawing apps as well, my palm resting on the screen causes random zooms and makes drawing a pain.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Lodix:
I said that the app could be the problem, cause with others it does not happen and in normal use I don't have this problem either...

[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] jaytee23:
It's not the app. It's not even a multi-touch problem. It's a touch problem, period. Play ANY game where you have to have keep a virtual on-screen joystick pressed in any direction for 30 seconds or more and watch how it disengages by itself after a 30 seconds or so. Watch how you try to re-engage it and watch how it disengages again, sometimes immediately. This happens in every game of this type I've tried. Whether it's an on-screen joystick or gas pedal, it will disengage after 30 seconds or so of continuous contact. Try it. Tell me I'm wrong. And the reason it's not a multi-touch problem is that this will happen even with only one point of contact, ie. on a virtual on-screen joystick. A second+ touch is not necessary for the behavior at all. I have another Android device (an LG Optimus G) and I can play the same titles on it and not have this issue. The issue is in the touch-system of the Note 10.1 and it's major and totally unacceptable on a flagship device of this cost. I cannot tell you how pissed I am that this issue hasn't been addressed yet - and it seems like Samsung hasn't even acknowledged it yet. What kind of craptastic company is this? I'll tell you what, if LG had a recent 10 inch tablet with similar specs, I would have been all over it. The LG software loadout is so superior to what I'm seeing on this Samsung. I will be hard pressed to buy Samsung again.
