Is anyone working on a fix for the appalling 8.9 touchscreen sensitivity? - Galaxy Tab 8.9 General

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

Capacitive Button Responsiveness?

Recently, I've been considering getting a Nexus One, however, most of the reviews I read say that the N1's capacitive buttons are a little unresponsive. You must tap the upper half of the button as opposed to the bottom half of the button.
I've also read that some of the cyanogen roms have fixed this problem. Can anyone give me more insight on this issue?
I've never had a problem with mine.
I saw a review saying that they got in the way when typing w/ the onscreen keyboard, but I haven't even had that, and I'd like to think that I have pretty normal-sized fingers.
Some people have problems, others don't i personally haven't. I wouldn't consider it to be something important enough to sway me from a sale though.
Stock Rom had this issue. If you unlock your bootloader, all the kernels (and mods) available now have a fix for this, as well as a few other things.
Im sure when 2.2 update comes out this fix will be passed on to the stock version too (at least as far as im aware it hasnt already!?). So tbh this isnt an issue for you not to get a nexus one...also, there's no point getting a nexus one if ur too scared to unlock the bootloader!!

Definitely! That's one of the biggest reasons why I want an N1. It has a good root and dev community and gets android updates first.
I just thought it'd be annoying to have to use a phone with crappy capacitive buttons, but I'm glad to hear that the problem has been fixed.
The only other thing I'm worried about is the dualtouch but it's most definitely going to get fixed in the next update.
Thanks to everyone for their input. I'll definitely be picking up an N1 soon
I have rooted and custom roms etc and I still hate the capacitive buttons with a passion. They are not nearly enough to topple the overall awesome that is the N1 but man I hate those things.
I only hate those buttons, when Nex is in my car mount!

Is this true? I've tried plenty of ROMs and kernels and I don't remember any of them changing the button sensitivity.
The best way to show off how frustrating the buttons can be is to give the phone to someone that's never played with it before and watch as they struggle to register touches on the buttons. The people that use the phone daily have recognized that the touchpad is above the button and never think about it any more.
It's very apparent as soon as you rotate the phone into a different position though.

I also haven't noticed any change in the sensitivity with different ROMs or kernels. For me though, sometimes if I hit right on top of the button it won't register. I am used to just tapping it a little above and it works everytime.
As others have said, this is definitely not a deal breaker for me or shouldn't be for any person IMO. This phone's pros far outweigh the cons.

When someone is doing that you should just say that it has Finger print authentication technology
absolutely true and this was my discovery today (day 4 with n1). the buttons work fine if you cheat towards the top of the button area and overlap into the screen area.
that solved it for me.
resolved for me for now...

Did you just buy your N1 from Google brand new?
Those buttons are a pain in the bum, but you get used to them, the bigger problem is if the phone gets too cold it starts mis-registering the touchscreen necessitating a reboot or a bunch of mucking around to fix it. This is the biggest annoyance with the phone for me, hopefully they fix the screen calibration in 2.2!
Almost swapped mine for a Desire, thinking less of doing so now, unless anyone can offer a good reason
I got my N1 straight from Google on day one, and I'm currently running CM 5.06
I find the capacitive buttons to be _awful_ if I tap directly on them it takes 2-5 attempts to get it to register.
However, I have found that if I swipe from the button down off the bottom of the button it registers ever single time.
I'm pretty convinced that the problem isn't the digitiser itself but in the driver that splits that section of the digitiser off. I believe it checks to see if there is upward movement before registering a button tap and if it does detect upward motion it cancels the tap event and forwards the event as a touch screen event. I also thing that because I have pretty big fingers any time I press the flattening of my finger registers as a slight upward motion.
If I could find the button "sub"-driver I'd be hacking at it right now.
Still, I wouldn't give up my N1.

Just realized that!!
It does not get the upward movement
It gets: right, left & down
So this means, one could set different options for different directions...

I have noticed no issues when holding the phone in my hands but the responsiveness is not that great if the phone is flat on a desk or a similar surface. I wonder what if anything the accelerometer may play a factor.

I dunna man, my 3-year-old daughter figured it out within a minute of getting my phone. I set her up in a game and she decided she wanted something else, so she messed with the capacitive buttons until she got out of the game. Once she had it once or twice (~5-10 seconds for her to figure out each time) it was pretty much instant after that. If a 3-yo can figure it out, I'm pretty sure it's not THAT difficult. Annoying, sure....but not difficult.

Yes. Direct from Google.
Wow there's definitely a good mix of answers. I thought that the newer batches of N1's fixed the capacitive button problem, but apparently not.
I guess there's not a definite answer. It seems the only conclusion you can make is that some N1's may still have the problem, some may not. Some can be fixed with custom roms and unlocking the bootloader and some cannot. Your results may very.
EDIT: After rereading some of the previous posts (more carefully. excuse my sleep deprived state lol), the capacitive button issue might actually be more of a feature than an issue. I've read similar posts about the capacitive buttons having that sort of "motion detection" thing to prevent accident presses. Hopefully for anyone still having the problem, you can reread some of the posts on this page and give their methods a try
I haven't had a problem with mine but I haven't had the problems most people say they have with the phone so I would recommend this phone to anyone that wants an android phone

Nookie Froyo Users!!! Touch Screen corners.

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.

[Q] Touch Screen Responsiveness

Device: Nook Color rooted to 1.1
I had my Nook Color in the car today (40 degrees or so), pulled it out to show her what it looked like rooted. While standing in the driveway showing her different things, I found the touch screen was overly sensitive. As I was scrolling through different things (the app list, twitter, facebook), the slightest touch would select/open an item. It normally doesn't do this. It was incredibly frustrating and almost unusable. I pulled it out later and it seems to be behaving like it normally does.
Does temperature affect the NC screen? Where they any touch screen changes in 1.1? Is there a setting to calibrate the touch screen? I can't seem to find one. Any other suggestions?
I tried doing a search on the forum, but the search crashed.
Thanks.

As for the other question, I would expect the screen to be less responsive in cold weather, but I don't have anything to base that on.
Guessing what you experienced was due to condensation on the screen. Doesn't take much and can be 'invisible' to you but the screen is sensitive to 'stuff' on the screen and will become overly sensitive if there is anything on it, like moisture, skin oils, etc .. a screen protector may help but unless it continues that is probably the cause.

What you experience is probably temperature related, but another thing to try is to increase the LCD screen density to around 190, 200, or a little more. For me, I get improved sensitivity, especially near the corners.
My daughter accidentally got a little water on the screen and it was a little erratic. I put it in a ziplock with a handful of rice for about 6 hours and it was like new.
I have owned 3 nook colors, the first one I owned freaked out when I used a damp cloth to wipe the screen. It exhibited some strange behavior and emitted some loud static from the speaker. It would not power down or anything... finally it just went back to normal, so I took it back to B&N and then went and bought one at walmart. I took it back because I thought I wanted the Viewsonic G Tablet. But after trying it I finally bought a Nook Color at Best Buy, bought a screen protector too so that I don't have a repeat of my first NC. The screens on these things are, I believe, rather sensitive and the cold or the moisture may have played a part in your unit's behavior.

Same here. My screen also seems very inaccurate.
Have you found a fix?

I'd be interested in a solution for this as well, since the edges of my NC screen seems to be a lot less sensitive. For instance, when the Market is launched, it takes 4-5 tries to hit the search button at the right top corner (I know that I can hit menu and select search from there, but I am trying to illustrate my point).

It's funny, actually... The cold makes your skin less detectable because of vasoconstriction in your fingers as a physiological response to the cold temperature, but a hint of moisture by means of condensation has the opposite effect.
For me, condensation is rarely a problem, but the decreased capillary blood flow effect is quite noticeable.

One thing that's been mentioned before (and the B&N salesman told me while buying a screenprotector) is that if the screen has a lot of fingerprints, it'll make the nook act weird.
Try wiping the screen of fingerprints.

Thanks for the reply. Is it safe to assume that the screen sensitivity would not be an issue in Honeycomb since it is designed for tablets? If so, I may just wait for the final release of HC before fiddling with different kernels,etc. Thanks!

final realease of HC? no one knows if we will ever have one...... anyhow, it seems to be a fix at kernel level (had to be fixed in eclair, froyo and HC), and it fact, it was discovered by deeper (the guy who ported our HC version)
my suggestion? go for it now. the sensitivity problem is way too bothersome, and it is very easy to apply

Yes, I'd love to take care of it ASAP, since I'm sick of trying to hit a small button on the screen and going somewhere else instead.

Good test tool
I ran GoJimi's tool, and since then my screen has been flipping out. Typing anything is a good test...I enter one key like "z", and get 2 - "zm". Utterly maddening.
A good tool to see what's going on is "Mutitouch Test" from JerryW in the market.
When I press with one finger, I see a "phantom" 2nd point jumping around. Very quick way to see 1) how good tracking is and 2) if there's any random inintended multitouch action happening.

Getting a better look at this multitouch issue, with some good ol' community feedback

Hey guys,
Thought I'd post this here and keep you guys updated on further developments.
I live in the Netherlands and bought a 32GB version at Dixons at the 13th of November 2012
I had found the touchscreen a bit unresponsive sometimes in the past.
But couldn't really find out why it was acting up. I finally isolated the issue.
It is exactly the same as this guys vid:
(Thanks for the vid injahnet)
Together with a little backlight bleeding, I decided to send for repair.
(The problem persisted after a factory reset, no other apps were open when testing.)
I went back to Dixons and showed the problem to the Dixons dude.
He acknowledged there was an issue and sent it for repairs or replacement.
Due to the holidays this can take some time. Maybe even next year
I was about to open my tablet for a look inside one of these days, boy am I glad I didn't do that yet
Anyway to get a good view on this issue globally, are there more people that have the same issue?
You could go to: Settings > Developer options > and then under "Input" you can enable Show touches. and try to to the same procedure as in the vid. (Thanks Peterk-1)
Or you could test with MultiTouchTester like Injahnet.
The weird thing is, my dad's N7 16GB does the same.
Update 17-12-2012: Please do not test while plugged in as the device will be grounded and the issue will not occur. (Thanks dad)
Feedback is really appreciated!
Please vote in the poll above!
Cheers,
Daan
I have zero problems with multitouch while using my Nexus 7. Working just fine, but you must disable any apps which interfere with gestures or it'll steal events.
Can't say I've ever used multitouch with the N7 laying on a random object however.
But sure, send it in for repair......... I'll keep using mine.
If anyone thinks they have multi touch problems then loading an app isn't required. Just go into Developer Options and under Input you have two options to display touch and track detail.

At the moment of writing we know that three people are having this issue.
I know someone else with a nexus I'll check if he has the issue too.

Yes, i have this problem. And only while device is laying on the table.
Wow, this is bizarre, thanks for pointing it out. I can confirm it happens when it's laying on my pillow, and doesn't when I'm holding it.
Thanks for the vote guys.
By the way, it seems obvious that the Nexus should not be plugged in while testing.
However I cannot test this 'cause mine is at the shop
Would anyone be willing to test?
I'll add that in the original post (+ a mention of your name and a thank you of course))

if the two touch-points got the same X or Y coordinate my nex7 does only detect one of them. i don't think this is an issue.

However, zooming in Google maps for example will become quite difficult
Anyone try and see if taping the ground pin on the wifi antenna fixes the issue? This seams like a grounding problem.

Exactly! I was also thinking of this.
Do people who have this issue also have the flickering issue!?

Just an FYI, I installed CM 10.1 with Trinty Seven. Now I get 10 touches on pretty much any surface.
I don't have a multitouch issue, but I do have an entire band on my screen which has stopped responding to touch at times. It all started when I let my tab shut down due to low battery. Initially, the Nexus 7 neither charged (when put on charging, obviously), nor did it boot up. After trying for several hours, somehow it started charging. And since then, sometimes certain areas of my touchscreen become unresponsive to touch. Since the band which is unresponsive is towards the upper part of the screen, using notifications becomes completely impossible. It keeps 'snapping back up' when I try to pull it down, cos while I am pulling it down, the notification tray encounters an unresponsive area, so it just goes back up. Called up Google and they will be sending a replacement device. All I am afraid about is that I have an 8gb version, and they would be sending an 8gb as well, so I hope it isn't refurbished or something, as Asus has stopped making the 8gig model.
I'm having an issue where the screen, ( mostly in a webpage or document,) starts moving up and down and zooming in and out without my input.

Just tested this out and yes, my device is doing it too. Interesting. No other issues like screen flicker (except the auto brightness bug in 4.2). My n7 is c9O

Community feedback is failing hard.
Anyway, I'll keep you guys posted on the repaired Nexus.
At the moment of writing we know that three people are having this issue.
I know someone else with a nexus I'll check if he has the issue too.
Cheers,
Daan

community feedback is not failing hard, more like you're just starting a new thread without bothering to search if issue/topic already exist.
this isn't new and there is no fix, that is just how the touchscreen function. the N7 isn't the only device to have this.

Don't feed the trolls!
Must... not... feed... aaargh....
You are kinda missing the point of this thread.
It is to see how many people have this issue.
There is no thread capturing that in an easy way unless you want to count every post.
Now please tell your brain to start functioning again and leave this thread alone if you have nothing to add.
Asus Google Nexus 7 32GB touch death zone
Hi DaanJordaan,
Found out that my brand new N7 seems to have a similar "no touch zone" issue; an area the size of my little finger on the left lower part of my screen does not seem to react to touch! It interferes with typing the keyboard in portrait mode (no keyboard problems in up-side-down portrait mode).
When I use the Easylabs Multi Touch test I can see the dot changing color when I move over this area, doesn't happen anywhere else on the screen..
Using the developer tools (turning on the two options that allows to show touch/leave a trail of touch) it becomes even more clear that this area does not react to touch! I can "paint" lines around the "no touch zone" (it actually splits into 2 touch areas using one finger around the "death spot"), and the "no touch zone" reveals itself by not showing any trail/history line of touch..
Oh yes, and it does not matter if I lay the N7 on the table, or hold it in my hand, the issue is always there.
Therefore I returned the N7 back to the MediaMarkt, and they will send it in for repairs...
I've got a bad feeling about this | - )
I am curious to hear about experiences with your N7, once you have it back!
I'll report mine here, in three weeks or so (that's the outlook...).
Cheers!

Multitouch with +5 fingers

****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.
