It seems that corner touch screen sensitivity issues are prevalent among all nook color users. What I'm wondering is, does nookie Froyo have this issue as well?
Yes, or at least for me.
No difference on nookie froyo for me either. I'm pretty sure its a hardware defect and not a software one.
I'm on a rooted stock, but my edge sensitivity issues went away when I loaded one of the overclock kernels. I don't know how the two could be linked, but it is the only explanation I have for the difference. I'm not sure if that's been explored on Nookie, but I thought I would share since that would point to a software issue rather than hardware.

That I'm not so sure of. Using "Touch Test" I see all touches, but they seem to get shifted slightly when I press near the edges. Maybe this could get solved in the driver (maybe with some help of calibration tool). I hope to have time to play with this sometime soon.

How can you be so sure?
If i use google market, sometimes the search button is hard to press,
but using appbrain market it works 100% of the time without problems.
No its not H/W I think, run some tests and corners work fine.
Its certainly something else, I also have better response after loading OC.
I've seen the same thing (I would bet every nook owner has.) The Market Search especially takes *%)(!%&! forever to get to work for me.
I've seen the same behaviour as well, some apps the corners take 18,013,108 tries to get to work, other apps I'm all "Whoa, first try and it worked?!".
I put the 950 OC on my autonoot but then I started playing with Froyo on a C10 SD card (very quick) so I don't know if the OC's actually helped with the corners or not. And of course this is the one day I leave it at home since I got it.

Use Menu>Search instead of trying to touch the top magnifying glass.
Happens to me with Froyo. I seriously doubt its hardware related. Seemed to work fine on the stock B&N.
It is common for digitizers to be less accurate along the edges but the Nook Color seems worse than normal. I've noticed the problem regardless of kernel or rom used.
I'm pretty sure it has something to do with the LCD Density. All buttons/elements are a lot easier to press when I switched to 240-250. It does look ugly though, it'd be a lot prettier when we get a custom rom running.
Sigvard is right. Fixed for me by chaging my LCD Density. I set it to 200, which is a little too large for me, so I may lower it. But since doing that I have had no problems at all.
Guide here: http://forum.xda-developers.com/showthread.php?t=889951&highlight=LCD+Density
Ha! I have the exact problem even with stock rom. I though it was the problem of the particular corner of the unit I got! It is much easier to press the button in landscape view.
I dont believe its the screen. Download AppBrain and tap the search button. it works 100% of the time
It is the screen. Use a drawing program and notice how it is easy to draw a straight line in the middle and not as easy on the sides and corners. Note, you need to drag your finger slowly or else you will see more interpolation.
Raising the LCD density just hides the problem by making the hit zone bigger. Fortunately, I can live with the it.
I know that there is the build prop "fix" which helps slightly (changing one of the values from the default 150 to 300 - can't remember which but you'll find it with a Google around). However, I was wondering if anyone is working on the touchscreen of the 8.9, or has any ideas on improving response sufficiently so that handwriting is feasible.
It seems that there is some kind of filter that disregards small movements - you can demo this but putting your finger down on the desktop and wiggling it from left to right about 2mm or so. I'd expect to see the screen "wiggle" slightly, part scrolling from left to right. Instead after a few seconds it responds as if you have held your finger down motionless. This is the issue that makes handwriting impossible.
On the 10.1 there is the app and discussion thread TouchScreenTune which fixes all of this. I have tried it on my 8.9 but no joy - but I can't imagine there is much in the way of difference between the two devices, and reckon that the 10.1 fixes could easily be applied to the 8.9 if someone with a bit of knowledge applied themselves (that's not me, unfortunately)

I think we have to contact the dev of touchscreentune and get him on board of this since both devices is kinda similar.

i sent him a mail. here are the responses:
it seems unlikely:
- I don't have the device
- it uses different touch controller than 10.1
- kernel doesn't support configurable parameters for 8.9

I'm speaking about driver provided for controller used in 8.9, it has
no possibility to change configuration. And the firmware of the
controller is a binary blob with no documentation.

looks like we are unlucky
being very upset with this problem i started poking around the build.prop
it might be placebo but i feel that when this is added:
Code:
windowsmgr.max_events_per_sec=300
it gets a little more responsive. still not what i want it to be but better than before.
Try Touchscreen booster
It seems to have helped mine.
thanks. seems a little more responsive.
here is the apk if anybody else was wondering:

My 8.9 LTE is super sensative, probbly the most I have seen on any android tab.
I can just barely graze my screen with rhe back of my fingernail and it even picks that up.
Compared to my roomates ASUS Transformer Prime, wo cant even use his fingernail unless he really jams it down.
iinteresting but im on the tegra version which aparently has completely different hardware
hi everybody
I'd like to try to find some answer to the annoying problem of the touch filtering.
I've been searching around the internet for days, I've also asked the author of TST but with no luck till now.
Is there anybody that knows or can address me to how this problem can be solved? I don't think it's just a hardware problem, but a software one.
I'm also willingly to write to Samsung directly, so wish me good luck.
If I'm not gonna find a way to do this in a couple of weeks, I'm quite sure I'm gonna sell this beautiful black useless brick to an iPad.

that's been the first thing I did, but the improvements it brings are very light.
Does the tablet really have different hardware between the wifi and the LTE version? (at least regarding the screen digitizer)

Hmm, is it really a sensitivity issue? If I swipe first then wiggle like you mention, the screen will wiggle slightly. It sounds like there is a threshold to switch from holding the finger down motionless, to scrolling from left to right.
Perhaps a threshold setting (if available) is sufficient to overcome this?
I'm noticing the samething. When I first saw this thread I thought everyone was crazy but after trying to type large amounts of text I've found it incredibly unresponsive in landscape mode (though portrait feels perfect!). I'm eagerly waiting for the official ICS update as in hoping it'll fix some of these issues.
It would be nice if they at least updated us to 3.2.

I have Samsung 3.2 OTA update and it really changes nothing.
Btw no answer yet from Samsung, and yes, the problem is just about some sort of accidental touch filter
Is there any programme to for screen calibration? So part of the screen seems not responsive.
That is a hardware issue not a Calabration issue..
does somebody know if this "hardware issue" is present at all note's?
i found that my screen is a bit unresponsive at the top right corner. i cant draw about 2mm to the border of the screen (with the pen)!

However when I flash a new rom the screen get responsive for a short while. After that I need to press the screen harder. On the bottom right hand corner has this problem.

Did you ever solve this problem? Mine started doing it after it updated KL7 OTA.
Well guys I'd like for someone to chime in on this. I thought for sure this was a hardware issue. I'm on my second note now. My first note seemed like it was having issues with the lower right corner of the touch screen. I thought maybe it was a rom issue. I flashed clean KL7 and it seemed to suddenly be better then after a little bit it got worse. I have my second note and I flashed KL7 right away on it. Now after a little bit it seems to be getting less responsive, still better than my first, but I'm beginning to think this is a software issue. Any of you having these issues what Rom are you on? Should I try changing out this note for a third and see what happens? I may flash to some other firmwares to see too.
my top right is a bit unresponsive as well. . it works but seems a bit off. .
I used swipepad , really useful taskswitcher
It does not work when phone is connected any charger.
I've definitely noticed the phone being less responsive when on the charger, but this seems to lose responsiveness over time off charger and on battery.
I've had other phones that from time to time would act a little wonky when using them while charging.
Hey,
I've had some display problems, both with regards to calibration and also when it's charging.
I have made this video to demonstrate a problem I have of calibration. Watch how the display detects a signal at a point offset from where I press with the pen.
For me the problem I saw using the *#*#2664#*#* test is that the last 10 pixels or so on the 2 end sides of the screen don't respond.
For the pen offset is cause of the left or right handed settings, I find that holding the pen and rotating it so that my thumb presses the button of the pen instead of the indicator finger gives pretty good accurate results.
I'm definitely thinking this is at least more software related than hardware. I don't remember noticing any problems when on KJ1 or KK1. So I flashed back to KK1. It started it up and then I did a quick factory reset. This is completely stock/unrooted. Anyway bottom right corner seems to be having no problems detecting my touch now. I'll leave it on this for a few days and play around and see if it seems to lose sensitivity again. If it does I'll let you guys know, but for this to be a hardware problem I can't imagine it being this intermittent. Any of you on KL7 that mentioned this issue, are you guys completely stock KL7 or using the CF-Root Kernel? I know someone mentioned losing functionality in music player and torch and it seemed to be an issue with an alternate kernel.

That´s normal - pen is calibrated to use it at a certain angle - try to change the setup from right handed to left handed and you will see a different offset if you make the same test again.
The offset should be the same on each area. Only if this is not the case i would say, there is an issue with the screen.
Hey, ok so it is a deliberate software decision. Kinda sucks- I'd think I'd sooner like to have it type directly below where I write. I'm guessing it is an attempt to account for the fact that the glass has a finite thickness. Sooooo does anybody fancy writing a kernel alteration for this...?
i also find it more annoying than useful
Couple days on KK1 and what I thought was a hardware problem still seems to be fine. It's detecting much better in the bottom right corner where I was having issues on KL7.
I am having the same issue with the reduced responsiveness of the bottom right corner. I've noticed it after updating to KL7. Maybe is the driver of the screen.
Is there any way we could report this back to Samsung?
Sent from my GT-N7000 using XDA App
Hello.
I have the same problem ate bottom right side of the screen. I am ate LA4.
what should I do?
Although the problem was nearly imperceptible some days ago, while the note was connected to the charger, I've noted a very small area near the bottom right side of the screen where it was difficult to write using the stylus with SMemo. On the opposite side the loudspeaker is present; and so I've thought it might be correlated with the magnetic field of the loudspeaker. Today I've performed the *#*#2664#*#* test with and withouth the charger, but the problem is not occurred. Because of these devices are always more complex I prefer snap closures for my cases.
hey guys,
having said that I tried a lot of methods such as the "automatic recalibration"..I really can't believe that we don't actually have a specific app for recalibrate our big touchscreen..it's so annoying when you put the S-pen on the screen and you see the pointer with 3-4 mm offset.
I'm running ICS Stunner 4.3
If my pen has an offset all I need to do is to wiggle the pen in each corner at the edge of the screen for a few seconds (like drawing small circles over eachother) and the offset is gone.
are you on stock rom? cause I'm not..and I think this is why it doesn't work for me.
I'm using Rocket Rom V23 with SpeedMod kernel 2.8.
The thing I've noticed is it depends on the app I'm using, it seems that the stock Samsung pen apps all use a small offset while the pen is way more accurate in Infinite Painter.
When my pen offsets I rotate the screen to portrait then back to landscape(or the other way around) and it usually sits bang on again.
Hi mates
Few days ago I've encountered a very annoying problem while using s pen
When I'm using s pen in whatever app (S note, iAnnotate, Adobe Reader...) I'm encountering offsets in whatever direction. Most often to the right side of the screen. S pen touches the screen, but the line appears 3mm to the right and a little down.
When I'm using hand no problem occurs!
But when I'll run Crayon physics and using s pen. No such thing as offset occurs!
WTF?
Have anyone of You guys encountered such thing? How can it be solved?
To be honest, I'm getting nervous more and more :/
I'm on:
- stock, non rooted ROM;
- system version 2.3.6, kernel 2.6.35.7;
- version: GINGERBREAD.XXLC1;
- modem version N7000XXLB2
I know this sounds obvious but did you try changing Pen settings from Left handed to Right handed / back again in the dominant hand settings? Someone reported that this seemed to rest the offset. Personally I found if I rotated to landscape and back again it seemed to be better, but never really had a problem.
Sure I did mate. Didn't help me to much :/
I've also tried to rotate to landscape and portrait - it helped, but only for a little while.
What is strange for me is that this kind of issue appears in apps and in keyboard while I'm on s pen, but never while playing in Crayon.
And I've played a lot today. And without any offsets
If also in game I would have encounter problems, then I might have start thinking that this issue is caused by damaged s pen or the screen itself.
I was also thinking for a while that it's caused by software I've installed. And I have a lot.
Now I'm using sslauncher and LWP - Galaxy Pack. Those are my two types.
But it's also rather impossible for me that some apps can influence on s pen behavior in general, but not in game?
****UPDATE: *****
This is what happens https://imgflip.com/gif/1xvxm0
What can be the cause of this? Does this happen to any of you as well? Should i open the casing and see if there is anything touching the metal casing that should not ?
****EO UPDATE ****
I have been testing with both
Settings -> Developer Options - > Show Pointers (and looking at the top left that says x/x points)
or
Using a multitouch test app like so https://play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester
The latter is nice because it has big handlers and you can clearly see the point/touch flickering like loosing and creating point (hence creating a new point ID)
From what i can say in Marshmallow it worked way better, on the last 2 Nougat updates i saw that at the 7th point it started to do the flickering and with this one it starts at the 5th point.
With 3 fingers screenshot disabled (and all the gestures for that matter) as i know it would create a conflict.
Just tested in a Motorola with Marshmallow and it created the 10 points flawlessly.
I wonder if any of you noticed the same or is something off with my touchscreen?
Might it be a Nougat thing ?
Any known solutions?
I searched around and nothing Nougat related seem to pop up
Just tested with both OP2 and a Moto G5 and they both work great, actually it even worked great on my Samsung Galaxy i9000
I have noticed that for the last 2 updates or so multitouch capability has been decreasing.
When are you ever going to use ten fingers to multitask? If it wasn't for the screenshot gesture, we wouldn't even be using three.

That is irrelevant for what i am trying to figure out, what i want to know is if it is a HW problem by default or just my HW is faulty or even if it is a Nougat problem.
It works flawlessly on other less capable phones
Either software or hardware fault I would say. I just tried it out without any flickering with 10 fingers on my 3t running latest unofficial LineageOS 15/Oreo ROM.

Thank you, from what i get so far is a Nougat thing, all the users that have Oreo seems to work fine
Conductive electricity ?
Ok some pretty strange updates...
I accidentally tested it on a metal table and it worked perfectly, which lead me to think that it might be due to conductive energy or something.
So i tried the test on a wooden table and it does flicker and loose touches, so i pressed with a finger on a metal part of the OP3T casing and the points are registered properly.
I had made a video so people don't think i am crazy here is the result https://imgflip.com/gif/1xvxm0 at this point i can say that is directly related.
What can be the cause of this? Does this happen to any of you as well? Should i open the casing and see if there is anything touching the metal casing that should not ?
anyone ?
This is a non issue honestly. If it doesn't change how your phone functions in day to day practical use, you probably shouldn't bother with something like that. The touch display functionally is fantastic especially the screen colors and with the recently fixed touch latency it does happen to be one of the best screens on the market despite its lower resolution. Factually you won't use more than a three touch input so. IMHO

It is definitely a problem did you watched the video ? because it seems like a real hard problem to me, use cases for you might be different from others. My old samsung galaxy i9000 as well as my OP2 did not had that problem
It may be a problem for one and may not be a problem in another's eyes.
To address your issue, have you tried switching ROM's? I don't think it could be a Nougat problem, but you might as well try Oreo or even MM.
This may sound funny, but have you tried with another person's fingers?

I had the feeling that it might be from the updates (still using official OP updates) but right now i think it might be hardware. Yes i tried with other fingers, thinking about opening the phone to see if there is something touching the metal case inside.
