[Q] Are all screens broken? - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Hey, I bought my note 10.1 about a week ago because I was really excited about the Wacom screen for digital art. I've been loving this thing since I got it, and all the great drawing apps, but I tried practicing hatching to get better at drawing. What I noticed is that when I draw straight lines slowly together I do fine till I reach the middle of the screen. The tablet causes my lines to jump erratically . I tried adding a picture to show what I mean.
It bothered me enough that I took it back and exchanged for a new one. It's doing the same thing.
Is there anything I can do to fix this, or is this just a flaw I have to live with.. . I also tried testing it out in layer paint and s note as well.

Any waviness is me, not the Note...

Just tested mine n I get no bumps either. I can do hatching and straight lines without issue.
Not sure what to suggest, other than maybe changing the sensitivity of the spen.

There is an h/w issue with the digitizer... Read somewhere (here, but can't find reference, so don't quote me....) But apparently the digitizer is NOT behind the display, rather its baked into the GLASS....
This may explain the input instability. problem is, its not reproducible in the same spot every time, so I'm not sure exactly what is going on

[Q] Tab 2 7.0 w/ Stylus

I use a ZooGue stylus with my Galaxy Tab 8.9 (Stock, non-rooted) and it works GREAT for drawing.
I recently purchased a Tab 2 7.0 (P3113) for my wife (she likes the smaller form factor) but when attempting to draw using multiple drawing apps it is extremely choppy. When using my finger it seems to be better, but she really wants to use a stylus. I've looked thru the settings and can't find anything that would make a difference. I've also looked thru the forums here at xda and can't find anyone that has posted anything similar.
Has anyone else experienced the same and if so is there a way to fix this problem?
Thanks for any insight that could be given!

I think I've run into what you are talking about. I can't draw straight lines with a stylus. when I try to draw a line, the screen registers it as a zig zag. I'm not sure if this is what you mean by "choppy." I can draw lines fine with my finger.
I noticed that it's near impossible to draw in SketchUp - it takes 1/3 to 1/2 second for the lines to catch up to my finger.
I assumed it was just the compromise you make with buying a low-end tablet. I'd love to hear that it isn't!

Yes, that's part, as well as attempting to draw small circles/curves either skips or shows as a straight(ish) line. Hopefully a solution can be found soon otherwise this one is going back.
Indeed.
I noticed this issue from day one since the first thing I did was play Draw Something. No matter the app, swiping your finger in a slow and steady manner will help notice the stutters/lag.
I also attempted to use a stylus because I thought there was some sort of weird calibration issue, but to my surprise, it got even worse. The strange zig-zag phenomenon appeared, making it impossible to draw anything. Even though it's only noticeable when you drag/swipe/draw something, it's annoying as heck. Hell, I even recently found a dead pixel in the middle of the screen, adding up to the annoyance factor.
Still got like 1-2 weeks available to return it to Best Buy, and I'm not sure what to do...

[SOLVED][Q] Any suggestions for wavy lines when drawing?

I have the Galaxy Tab 2 7.0, rooted with 4.0.4, and have not had any problems with it for the most part.
I recently downloaded Sketchbook Express to see how well the tablet could handle drawing. It handles it very well with one exception: the closer you get to drawing at a 45* angle, the more wavy the lines get. If I quickly swipe in that direction, it straightens out, but the slower I go, the more pronounced the waves or zig zags get. This happens using any of my fingers, the $20 Rocketfish stylus, and the $30 Wacom Bamboo stylus. All attempted on a freshly cleaned screen. I've also tried different apps with the same result. This guy had the same issue, as have others from what research I could pull up, but outside of unhelpful answers of "it's your stylus" (it's not), they all seem to have given up on getting help.
I've tried these apps on my friend's Evo 4G 3D, running Android 4.0.3, and had the same issue. I then tried on my rooted Xperia Play running Android 2.3.3 Gingerbread, and did not have this issue. I'm not entirely convinced it's an OS version that's making the difference, but I'm not able to find much information about the screens these devices use outside of "capacitive touch". I did learn that these screens use the corners to determine the location of input being received, so maybe moving directly in the direction of a corner is causing it to mess up?
Long story short, my questions are thus: is there any way to fix, calibrate, or compensate for this issue? Is it the screen, a hardware issue, or something else? Is there anything I can do?
Thanks for your time.

The problem is the digitizer. It's cheap. I think all of the g tabs have this issue. Mine is terrible drawing diagonal lines and even scrolling in landscape mode is choppy. Only way around it from what I can tell is to apply more finger surface area. That seems to fix it. But since you're using a stylus that's not possible. If you find a solution to calibrate the digitizer, please let me know!
I have the same exact problem and the same exact request. There must be some option to increase sensitivity to at least minimize this effect. It's the only flaw I can find on this otherwise wonderful device.
And honestly, for the prize it cost, I would expect this not to exist. But... I have it now and would like to be able to use it in it's full extent and power.
dammit
Nice to know I'm not the only one who notice that, but it's crazy how my finger seems preciser than my pen and even more, that in my Galaxy S the pen works perfectly. I was so happy to use some drawing apps on the tab but when I tried...
I tried in my Tab 7 2, then I'll try on my uncle's 10.1 just to check.
hello all,
just to report the same issue. i have same problem with my samsung galaxy tab 2 7" like you all here. i get this problem since the first time i bought it (about a month ago). drawing the lines and reading in landscape mode is choppy :crying: same as MrHyde03 said. i have been tested my cousin's tablet to draw diagonal line for comparison, he has galaxy tab p1000. and the line result i get, though his tab has wavy line too, but mine has more wavy line than his tablet. i didn't noticed his tablet has so wavy line, just a little. i did it with my finger.
i hope this issue can be fixed later.
could be a solution
I don't know if it's just for marketing or what, but maybe the original Samsung stylus is better for these screens.
I wish someone could certify this...

Hi guys, I have the same problem. Horrible response when i draw with a (cheap) stylus and perfect when i do it with my fingers. Has anyone tried adonit jot pro or Dagi ??? Maybe they increase the contact area and it solves the problem. If so, please tell us!!!
Thanks for reading and waiting for a solution.
I know this is an old post, but I can't just abandon my own thread! I've done quite a bit of research on this since making this post, and sadly, it's the way the screen is. Strange that my Xperia Play and Galaxy S3 phones can do this, but the Tab 2 was given such a cheap screen. I ended up selling it and putting the money towards a Note 10.1 with S-pen, which works as I would expect it to.

S Pen Calibration?

Hi,
I've found on my Note 10.1 that the accuracy of the S-Pen gets worse near the edges of the display. At the very edges it's off by about 1 mm or slightly more. I can't say it's really caused any problems but I'm wondering if this is normal and if there's any method to better calibrate it?
I've been having the same issue, or at least I noticed it recently...
Does anyone know anything about this problem?
This has been bothering me a lot lately, especially since i use my Note for note taking. Bump in case someone knows the solution.

Here's the response from Samsung support:
Thank you for contacting Samsung Customer Care.
We understand that while using the S pen near edges it looses accuracy.
We are sorry to hear that.
Please try replacing the S pen tip to isolate and fix the issue.
It is not possible to calibrate the digitizer.
Thank you for contacting Samsung.
Kind regards,

I''''ve found the S-Pen (as viewed by enabling the hovering pointer) loses accuracy the closer to the edge of the screen the pen is used. At the edges it is off by at least 1 mm. About 1 cm in from the edges the accuracy is good.
Is this a defect in my unit or are they all like this? is there any way to recalibrate the digitizer to improve accuracy?

I tried changing the tip with both types of tips supplied with the tablet and as expected it had no effect. Note, also, how utterly useless Samsung email support is. The only way to reply is through a link which sends you to a contact form to submit a new email from scratch. There's no incident number or any way to establish continuity.
In any case, I happened to be at a Microsoft store yesterday and played a bit with Samsung's ACTIV (sp?) pro Windows 8 tablet which has the same s-pen as the Note 10.1. What I noticed immediately is it behaves exactly like my tablet: the digitizer loses accuracy both when tilting the pen and especially when the pen is near the edges of the display. The amount of inaccuracy is just about the same too, about 1 mm near the edge.
So I suspect this may be a limitation of the technology or at least the technology as it's being used by Samsung (I'm surprised Wacom's stuff is not more accurate). I'd be particularly interested if anyone is NOT seeing this.
It also seems silly that the display cannot be recalibrated or the driver does not support remapping. This seems like something that should be pretty easy to implement.
On the positive side, I can't say that I've experienced any real accuracy problems when in actual use. Probably I don't tend to write so close to the edge where it might be an issue. It's more an annoyance that the cursor doesn't quite match the tip. It's actually less annoying than having my hand trigger s-note's zoom or the notification drawer every time I try to write something.
Too bad, samsung support is horrible. For me this problem is pretty annoying since I tend to write until the VERY edge (just like I do in real paper), so I guess I'll have to change my habits lol.
P.S: It's good to know that is not my faulty tablet, but something "normal" in wacom devices...

Yes, it is annoying. I wonder if there's any dev we can convince to write a remapping layer to fix this issue.

Mine just works fine, even on the ledges! Sometimes, but sometimes when the accelerometer is uncalibrated the S-Pen just stop responding well. I calibrate the accelerometer using this game https://play.google.com/store/apps/details?id=com.fgol.HungrySharkEvolution Just go on Options/Change to tilt control(If necessary)/Calibrate
It worked for me!

Thanks for trying to help .... the slight offset near the edges is no problem for me but i had a relatively bigger offset near the top (near the cameras) but that appeared to be due to the magnetic part in the book cover i had what an idiot .. i thought the camera had magnetic parts that do this and forgot the magnet of my book cover
So now what i really have is the offset near the edges
For me it's not an overall offset issue but just near the edges where it makes taking notes, sketching particularly difficult. It's very frustrating that these tablets aren't better calibrated out of box and provide no option for calibration. I'd be very surprised if this couldn't be fixed through software but would probably require support through the driver.
The other issue I have is that the drawing point only visually aligns with the tip of the pen when the pen is 90 degree from the tablet and you're looking straight down at it. Provided you hold the pen at a relatively steep angle and you angle the tablet so you're looking mostly down at it (say on your knee or a tilted stand) it's not bad. But once you deviate from that, say by putting the tablet flat on a table in front of you so you're looking at down at around 30 degrees, the deviation from where the tip appear to be and where the drawing point is becomes significant. I find this very frustrating. While I still prefer the s-pen to a passive capacitive pen, the fact I can't draw where I think I'm drawing makes it hard to work with. I've been using the tablet as my primary note taking device but I'm getting frustrated enough that I may go back to pen and paper and scanning.
It's probably not possible to fix this issue without hardware changes. Although multiple calibration profiles might reduce the effect.
I guess I'll have to wait for better hardware before I can finally live a paperless life...

N8010: serious touchscreen / display bug, probably affecting whole batch / model

Hi,
I made this video to demonstrate a rather serious Galaxy Note 10.1 Bug
that i've encountered on two devices, bought from two separate stores.
The first device was a Note 10.1 N8010 with Jelly Bean, the second (the
one on the video) is a Note 10.1 N8010 with Ice Cream Sandwitch.
Transcript:
Hi.
I have in front of me a brand new Galaxy Note 10.1.. its a WIFI-model
N8010. With brand new i mean i bought it a couple of hours ago--here is
the recepit.
I already bought a Galaxy Note 10.1, same type and model.. about 6
Months ago, but its touchscreen suffered from a very weird
touchscreen-bug that was somewhat difficult to reproduce. When I tried
to return the first model, the device went away for almost 3 months and
when I got it back the bug was still there.
Since I was using the device mainly for writing assignments and taking
notes (thats why i bought it in the first place) i gave it back and went
to another store to buy a new one, hoping that the first place will give
me my money back. I needed the device urgently and it was, like i said,
3 months and I had to make a decision.
Well, as it turns out, though, the new device, the one you can see here,
has the same bug.. and I'm going to demonstrate it now.
Right now, as you can see, the device is not in a sane state.. and the
display hasn't turned off since I started speaking. The 2, well, the 4
dots, here, here, here and here.. this one is shaking.. the 4 dots are
supposed to indicate touch activity but are rather ghost-dots caused by
mentioned bug. Here for example is another dot.. I can make several of
them.. I can use a couple of fingers.. and.. this dot is caused by my
hand, the other ones by said bug. I can't do anything right now.. I
can't press on any of these buttons.. I can't call the menu, I can't
switch the homescreen left or right.. I can't drag the.. this thing
here, whatever its name is.. touch input is pretty much impossible.
How do you cause this bug? It's pretty simple.. you roll the palm of
your hand over the display. I can demonstrate this.. I can already
demonstrate this on the lockscreen, doesn't matter.. now, there are 3
dots.. and again.. well, lets try that one again.. now we see 4 dots..
and I can't unlock the lockscreen with my finger. I can though do it
with my pen. Alright.. like i said, you roll the palm of your hand over
the display.. angle and corner don't matter.. current application in
the foreground don't matter either. When this state is active.. it's
going to be almost impossible, I already mentioned that, to use
touch-input.. and with almost I mean there are certain situations where
touch-input will partially work.. but in most cases it won't. Like
you've seen the pen works in this state.. and sometimes, but just
sometimes, it will reset said state. I'm not sure.. I'm still not able
to use touch properly.. yeah, i'm still not able but the pen still
works. Let's reproduce it one more time.
If you want to reset this state your only option is to turn off the
display.. there you go. This bug occurs on ICS and JB.. this device here
has ICS, thats 4.0.4 and my last device, the one that i wanted to give
back.. is running JB 4.1.2, i think. (...) This bug is a show stopper
for everyone who'd like to use this device for lots of writing.. and
it's also a trouble maker since the repair-guys have a hard time
reproducing it, even if you provide them with a comprehensive video.
Now, I hope this video will reach someone who has the necessary access..
because, i don't know, either I'm very, very lucky and get my hands on
two exceptional devices with the exact same bug or this affects the
whole batch or every such model.
I can show perhaps a couple of other apps if the device will let me..
which it won't right now.. Its probably time to use the pen. For
example S-note.. pen works.. touch doesn't.. it's the same story, it
doesn't depend on the application or lockscreen or mainscreen, whatever.
Let me repeat: In this state, when you see these dots, the display will
never dim or go to sleep.. so if you write something and you don't
realize that the device is in such a state.. and you go somewhere for a
couple of hours.. you will come back and you will see that the display
never turned itself off and that you lost lots of battery.
If you want to contact me, i provided my address below (...) thanks for
watching."

I don't know what kind of help anyone's going to be able to provide. It's either a s/w problem which if you've hard reset the device and it's still there indicates a h/w problem. There's been some strangeness on particular regional versions of s/w. For example, different S Note versions have had various problems and different versions are shipped in different regional ROMs. You said two Note's you've had have the same problem though which doesn't make sense if one was ICS and one JB which means they were manufactured at different times so not from the same batch. Are you using a case with magnets in it? Some people have reported strange display issues when the Note's near magnets which causes electromagnetic interference.
The Note's been out since August and sold in the millions and this is the first this type of issue's been reported. So, to your point, maybe there was a batch of bad displays that got out and all ended up in whatever region you live in. Or all versions of your region's s/w has some type of display driver bug. Mine (from August) has no touch issues either via the pen or capacitive touches and I enabled "show touch" in the developer's settings to test it. It's also a pretty obvious issue so if it were common others would have commented or posted also.
The latest 4.1.2 s/w for the N8010 is for the Nordic Countries and was released in March. From your accent I'm guessing you're in the EU. The Nordic ROM is multi-CSC so can be used on any EU N8010. You might want to try installing it via Odin to see if it changes anything.

No, what you've seen in the video was just taken out of the box. There was nothing close or attached, just a tablet and two laptops on a table. The problem was initially reproducible in two different cities on several separate addresses.

Yes.. and that was pretty much the only reason why I was so convinced that my device was faulty and went out to get another one in order to get back to work as soon as possible.

When touches are shown, yes. Otherwise, hell no.. it took me months to figure out what was wrong. I blamed all possible things for the various gitches that were a direct result of this bug.. mostly the apps I was using. When the touch-input freezes started to occur on a daily basis I started to debug.. which isn't that productive when you're not root. In the end I stumbled over the "show touches" option and was lucky that such an option even exists.

I briefly experienced this issue while using my Note 10.1 in a place I don't usually use it (my brother's desk instead of my own). I was able to reproduce the issue many times by placing my palm on the screen just as in the video above.
Strangely enough, I haven't been able to reproduce the issue since that first time. I use my Note 10.1 in a number of different places (lecture halls, library, home desk, etc.), but can't seem to make it happen again.
I'm running a rooted, deodexed stock rom (4.1.2) on a NT-8013.
me too
Don't worry, you aren't crazy, I get this too.
I'm convinced its caused by pressure on the display components. My reasons are the following:
If i roll my palm across the screen relatively lightly (but still with enough pressure for the device to respond to normal touches) this never happens.
However as soon as i apply a littly more pressure I can replicate this problem every time. (To those reading thinking that I am putting an unreasonable amount of pressure on the device - I am not! I see people much more violent with their tablets day to day with no issue)
Furthermore, the more pressure I apply the longer the touches will stay after i remove my hand, suggesting that the device is kind of uncompressing.
Finally the area in which this is worst* there are some small LCD 'Mura' - that is light spots on the screen you can only see from some angles, these are normally the result of pressure.
I dont know about you guys but my note is pretty creaky, I would guess that there simply isnt enough rigidity to protect the screen components from stresses caused by pushing down on the device. (Note that i dont get this problem usually unless the device is sitting flat on its back.)
Dont get my wrong, I love my note and these issues are fortunately only an uncommon annoyance for me during typical use. But, this is kind of ****ty build quality and i will have reservations about buying another device from samsung.
*(e.g. if i roll my hand across the screen this is the most common area for a touch to 'stick')

In situations where I wasn't able to reproduce the bug (that happened every once in a while) I used a simple workaround: lock+unlock the screen and the bug was reproducible again.

You're right. After realizing that the second device has the same bug, I was close to declaring myself mental.

Mine too. It feels cheap and the only reason I bought it is because of the pen.

What's your typical use? My typical use was writing and said bug made that very inconvenient. It basically prevented me from using touch-input after writing only a couple of lines..
Maybe a short update: I returned the second device, got my money back, and sent the first device once again to $REPAIR_GUYS, this time with a link to the video above.
I'm also thinking about buying a Note 8 if I get refund for the first device.
Bottom line: The tablet was supposed to replace all the cumbersome paper I have to deliver every week and I'm out of a working device since end of january. A huge waste of money, time, time and time.

Yeah if it wasn't for the pen I bet most people would have gone for something more sturdy/better screen/stock android.
It literally is the only device which can do annotation anywhere near properly though so Its a matter of priorities.

Typical use has been taking lecture notes for several hours a day, managed a years worth of university with it, and while its not perfect
it did save my back from having to lug around lots of books and notes.
I would guess that this issue is present on all devices, just at differing scales. Hopefully you can find one where it is at a level that doesn't
bother you, though I wouldn't blame you for giving up and avoiding Samsung from now on, must be a right pain.

I would say that if you are planning on using the note 8 for lots of writing, maybe try it in store first, its probably way too small for any prolonged period, I find the 10.1 cramped and I have relatively small hands/writing. (Not helped by the fact the pen digitizer gets weird towards the edges of the screen)
Anyways, good luck!

I never really used the whole screen for writing for various reasons:
1. the pen is not precise somewhere around the middle of the screen
2. the pen is not precise at the edges (as you mentioned)
Reason 2 is something all wacom digitizers seem to share (I remember watching a guy on youtube demonstrating the "edge-effect" on the note and two other, professional wacom devices), reason 1 I can't explain.
Anyway, I always ended up just using the upper half of the screen and that's basically the main reason why I think it wouldn't make much of a difference. But on the other hand my gut tells me that you could be right.
Right now I can't shake the feeling that the note is just some random entity in Samsung's massive brute-force output. Never mind the details or the quality, after 5 different pen-tablets the fifth iteration will be just fine. Sounds a lot like Agile SW development.. just with hardware.
Same problem, demonstrated by someone else:
Have two tablets stock and no root. I have none of the described bugs and these 2 tablets are solid and very well built. Solid as any tab that I have owned. That is a strange problem and probable a batch built on Friday about quiting time.
None of those issues could have been reproduced on my Note 10.1 (GT-N8000) from Germany. Mine was bought in October 2012.
Sorry to hear that you have gotten two faulty devices :-/

I have went through 3 of these tablets, ended returning each one to best buy. I absolutely love it for drawing and sketching....until the screens bugged up. All three of mine where the gray version, I'm tempted to pick up a white and give it a try.
Btw ...the second video posted in this thread is mine. :cyclops:
Interesting thread, after reading it I decided to test mine and it's not suffering with that bug, I'm in the UK and brought it 2 months ago, it's the grey variant

Thanks to both of you for testing.

Yep, all three had the same issue.
At first I thought the screen bug was from the tablet getting too hot while sketching (SketchBook). The tablet was pretty warm, not uncomfortable to touch or anything. Possibly overheating?
While streaming Netflix, the touch dots would randomly appear and not go away. The tablet wasn't warm like before when I was sketching and it wasn't even being touched.
Still tempted to try another one, i did love it when it was working and there aren't any other android devices sporting the wacom digitizer
Update:
After almost four months, some Samsung technician/representative reluctantly decided to issue a refund. Reluctantly because, and I quote, out of 100 times he tried to reproduce the bug demonstrated in not one but two videos.. he succeeded only once.
Not really satisfying but, oh well, if they dont give a f.., I won't either.
Any updates
Hi
I bought this Note for my girlfriend as a Christmas gift. She's loaded a few apps and mainly uses it to look up stuff on the web, FaceBook and things like that. The issue is the screen starts twitcihing and types random letters and will switch pges and change settings. I did a factory reset via the reset option in the settings tab. That did not help. I will post a video tonight showing the issue. Are there any other option out there??!!
Thanks

Touchscreen fixed with better USB cord on Note 10.1 2014
I have the same issue on Note 10.1 2014 SM-P605.
I've tried changing apps, dozens of keyboard settings, device covers, screen protectors, pen input, finger input, touching the corners to recalibrate, turning the divice upside down, locking, unlocking, running different tabs in chrome...way too much time on this issue.
Finally I found the cause.
A cheap monoprice USB cable attached will produce the problem 100% of the time.
Using a heafty stock USB cable works 100% of the time.
I spent three days setting up this new tablet. And it worked flawlessly, until the last day when I moved to a new room.
Now I'm loving it again.
i have problem in touch in several flashing my touch not working anymore anyone can spare me a helping hand to solve this issue sorry for my bad

Horizontal lines on Display

Hi, I recently bought an HTC U11 , it's been 10 days and i am facing an issue with the display. Horizontal lines appear when i touch the screen a lot in a short period of time. I am attaching a couple of pictures for reference. It look worse to the naked eye. Is any one else face this issue?
Thanks in advance.
I've had mine for a month and seen this happen three times now, I think. I'll try to get some photos next time. I have no idea what causes it. What do you mean by "touch the screen a lot in a short period of time"?
Mine did this too like 3 times.
I think I noticed it happen after wiping the screen with a cloth ( has got to do with pressure and the attachment of the digitizer with the screen I guess ).
It goes away with some fiddling around, I can RMA it, but I don't want to send it out.
Don't know what to do

Like swiping the screen repeatedly in a short period of time.
hey guys, what did you do - i have the same problem after 4 months of use .. never fell down!
same problem here but doesnt bother me , strange to see
I have (unfortunately) grown used to it. I can confirm it's due to rubbing the screen, but I don't need a cloth for it to show up; mine happens from my fingers. It's easily reproducible by quickly and repeatedly swiping upwards on a section of screen. Slowly swiping downwards on an affected section can then remove it.
Here's a photo of the effect across the whole screen. It is much more noticeable than it appears in the image.
I has the same issue too, I talked with the tech support, they said it seems to be a hardware issue and I should send it back for repair.

Interesting that they think it can be repaired. Do let us know how it goes
Reparied
I sent to repair for 2 times. Second I sent picture and video of the problem directly to the repair place, and they changed the LCD panel, and the problem has disappeared. So far so good.

I just notice that this seems affected by humidity. I just tried to exhale and put some moist in the unit screen then rub again while moist and the line disappear (this is during the line is visible). It feels like the coating reacts on the friction. That's what I think of. By the way I'm not using screen protector right now. If its working with screen protector put on, please let me know.
