One of my biggest complaints about the shield tablet was the sensitivity of the touch screen. It had the ability to pick up touches before my finger hit the glass. This lead to erratic navigation and painful text entry on the keyboard.
THe other day I managed to bring the sensitivity down just enough to make the tablet respond as I wanted..
Go into Settings, then the About tablet screen. Then rapidly touch the Model number option. This takes you into the Sensor calibration utility.
Running this utility will tell you not to touch the screen during the calibration process. Once the process is complete, the calibration data is saved with a reboot. For those people who have been having issues with the touchscreen no responding or issues with multitouch, then perhaps this method will help bring your touchscreen response back.
however I wanted to reduce the touchscreen sensitivity, so I tried a couple different things. During the calibration process I put my fingers on the surface of the touchscreen and allowed it to complete the process. once the tablet was rebooted I found that my touchscreen was definitely less sensitive, to to the point of having delayed touch response and double touches were not really registering too well.
I went back into the calibration utility and this time I just very lightly touched the screen with a single finger during calibration. To my surprise this seemed to do the trick. the touchscreen now responds to my in the same manner as my wife's ipad mini .. It is much easier to use overall. This could be all in my mind, and the sensitivity did not change.. However I am now enjoying the tablet alot more.
Fantastic tip.
I'd love to be able to do this, but tapping on the model number doesn't do anything on my tablet. I have the 32GB LTE tablet, but ti's still on KitKat. Are you on Lollipop?
Yes, i was on version 2.0 nvidia rom which was 5.0 lollipop.. However i have since updated to version 2.1 lollipop 5.01 and found that the touchscreen sensitivity was tweaked and nearly perfect without having to do any calibration tricks.. No more false touches...
However as a side effect, whatever they tweaked to fix the touchscreen caused the touchscreen to become unresponsive when charging the tablet with my antec 4 port usb charger. It worked without issue in version 2.0 and i downgraded to verify..
However version 2.1 touchscreen sensitvity is worth the hassle...also fixed all my lags and makes chrome usable..

That's a very odd issue but hey, at least one thing is fixed. The sensitivity fix is fantastic, no more accidentally placing units in random TH's in CoC.
Thank you for this tip! Fixed an issue I was having with the edge of the screen not registering when I tapped. :good:

I apologize, I'm not sure how old is too old to reply to a post here, but make sure you press rapidly. It's not like tapping the build number to enter dev mode, where you can do it as slowly as you like as long as you hit the required number of clicks. You need to click 4 times within about a second to bring it up.
So that works reducing the screen sensitivity, how do I increase the screen sensitivity?
Ever since I upgraded the UI to 2.2, the tablet has been pretty unusable. I gave up and toss it away for awhile. It's just useless registering 1 tap out of 5 or more.
I figure I would give it one more try. if you guys have any tip of increasing that sensitivity. I'd rather have too much and have phantom taps than not enough.
It was also very annoying that I specifically stopped the lollipop upgrade, and it got in anyway.
how can I fix sensitivity on kit kat ?

Hi!
I have the same issue while charging. Do you know any fix for this?
Thank you!
Cheers, been looking for this.
I was able to use this method to get the sensitivity just right but it broke multi-touch.
Really nice tip! Many thanks for this!
That no response issue after a few fast tab is gone,
I can enjoy rhythm game without problem now.
Instead of finger, i put a tiny box like 10g on it while calibrating.
I'm also having the same problems with the shield k1. It's especially apparent when my fingers get a little sweaty. Screen calibration doesn't fix this issue for me. The only fix I have so far is to keep them absolutely dry. I sometimes use powder on my hands and will go to the extreme of using latex gloves just to get the touches to register correctly. If you find any other solutions, please update this post.

Hi guys,
Please download and watch the 2 videos i made and try to reproduce it if you can.
On the keyboard i'm """literally barelly/not touching"""" the screen.
On notes, drawing that slowly i get that. Already tested on another unit and had the same problem...just wanted to see if i'm not alone here..
This is unpleasant... If you already noticed the problem please do coment if you fix it or...
I did calibrate the screen, messed with reg settings but nothing changed.
I'm just trying to see if this is software related or hardware related.
Thank you !!

Very strage...
about the second video, what happens if you move the finger rapidly on the left portion of the screen?... are the results identical to the results of the right portion (as you did in the beginning of this video)?...
if you encountered this with another device, it's probably reparable via software upgrade... I hope...
unfortunatly it does the same thing be it left or right
on both devices.
It's an alignment problem. Try realigning the screen, touching as lightly as possible on the crosses and not moving your finger until the cross moves. No worries. Mine did the same stock and never after I realigned.
Drawing
I was resigned to living without the ability to draw on my HD2 but I just tried drawing in notes and was pleasantly surprised that it works quite well, even with my fat fingers.
solved?
was this solved by the realignment?
no, it helps a bit, but still not 100%. Whatever I do, I can always make the keyboard go crazy. The touchscreen needs a better driver.
Hi.
I have a problem with my hd2's screen.
Often i press the wrong buttons when typing and so on, And ive come to the conclusion that its something wrong with the screen.
To test this ive gone to the file explorer and then grab the slider to scroll down and hold my finger perfectly still.
And even tho im 100% still it stills jumps up and down like crazy.
I can imagne that its this that makes me type the letter beside the one im trying to hit.
Anyone else has this problem or did i get a faulty phone?
Regards, Joakim
A few other people have reported "jittery" screens. Have you applied any of the decreased sensitivity hacks? I believe there's 1 on BsB tweaks, which is nice and easy.

Have you tried re-aligning the screen and secondly reduce the sensitivity of the screen using BsB tweaks? this might solve your problems
the screen is very erratic: often when pressing backspace seemingly in the right spot the screen will jitter and incorrectly register different parts of the screen. often during texts the cursor will jump to the beginning of the text for no good reason. i find that this problem is augmented in cold conditions or when my fingers are not 100% dry.
I am no authority on screen technology so can only theorize but i suspect the problem to be linked to the fact that Windows Mobile does not natively support capacitive touchscreens (the driver for our HD2s was developed by HTC ). Other mobile OS such as iPhone OS and Android do not suffer any problems like this. we can also rule out a hardware fault here as i own/ed three different HD2s, all of which suffer from this jittering. The next update to Windows Mobile purportedly includes NATIVE capacitive support, which would - i suspect - have undergone more rigorous sensitivity and usability testing and will therefore lead to a better experience on the whole. i suspect that we won't get a truly excellent experience with Windows Mobile until 7 is released. The Windows Mobile we use now is very ancient under the technobotox, which probably explains the frequent freezes, glitches and slowdowns our HD2s suffer on a daily basis despite the awesome specifications (and perhaps why - up to now, Microsoft have put so little effort into the intentionally generic and rather stale Marketplace).
I applyed the screen sensitivity cab and now it seems much better. ill report back tomorrow when ive used it a bit
help!!!!
i installed bsb tweaks 1.6 and aligned the screen,my hd2 still jitter
Right, since this is such a significant impairment (and some users don't seem to experience it), I decided to create a separate thread for it:
If anyone finds out how to properly CALIBRATE the touchscreen on Froyo on Blackstone, please post it here.
So far, the "msmts_calib=0x395.0x3c9.0x79.0x77" results in random keys etc being pressed on the left hand side of the screen.
Thanks

well, there is a bigger problem as the calibration part ...
in froyo it seems to be, that the calibration willb e done automatical and it is not necc. to do anything extra...
but the module/driver for touchscreen is buggy ...
better for testing is the app dotty (can be downloaded from market).
there you'll see, that if you press via finger middle botton, that it jumps on screen touch to left botton - only sometimes ......and with this bug it is almost not possible to use the phone via fingers ...
my boot paramter for calibration is: msmts_calib=0x395.0x3c9.0x79.0x77
but as told above ... the problem is the touchscreen doesn't work correct if using finger ...
if you use the stylus, then it is working, so i think it is a bug, that if the touchscreen driver is getting multiple zones on touching the display, then something strange happen, and then it add an extra point on the left side, which makes using keyboard (SIP) almost impossible.
the only questions would be: does this bug also happenon 2.1 ?
because it it is there working, then we can try to implement the driver from 2.1.

Slow down...
Slow down guys...
For 99% of users the calibration works fine, you're in the minority experience tolerance issues.
Touchscreens drift over time, and with heat fluctuations (quite dramatic ones only) etc.
You guys are just unlucky and have devices that have clearly drifted by some amount....
Now, there ARE instructions floating around about how to fix calibration issues, but they aren't on the Blackstone thread, they are elsewhere and I can't recall quite where, but they DO exist.
When it comes to used a finger instead of a stylus, here you just have to live with the differences between a resistive and capacitive touchscreen. Resistive is the one used on Blackstone and most other touchscreens older than 18 months old, whilst never devices tend to have capacitive screens.
What's the difference?
Resistive need physical pressure against the screen, but can be highly accurate in ONE position. You can use these screens with or without a stylus, so can be good for handwriting recognition etc.
Capacitive need NO physical pressure against the screen, but are less accurate.
However they can detect multiple presses at the same time in different parts of the screen.
You can't easy use these screens with a normal stylus and so they aren't ideal for handwriting recognition or fine detail work.
When it comes to using your finger on resistive screen, a lot of accuracy is lost... you're just pressing a large area of the screen and the screen can only deduce ONE point under your finger. This can lead to inaccuracy and wrong buttons being pressed with a UI that has tiny icons and controls.
If your touch calibration is ALSO out, then things get worse still.
Now, before any techies get too techy, there ARE some 'smart' techniques for trying to have multi-touch on resistive displays, but we will no go into that here, and they are generally 'hacks' that don't work in all scenarios.
You guys just need to get your displays recalibrated... that should cure 95% of all your problems, and the remaining 5% are just the stuff we all face... like no multitouch, pinch to zoom etc
It's definitely wrong to give the impressions that XDAndroid releases simply don't work correctly with touch screen. That's very misleading indeed.
i too have issues with touch screen accuracy (both 2.1a and 2.2 v1.0)
80% of the presses are fine, but the other 20% xdandroid would place my finger about 1" to the right, slightly down of when i first contact the screen, and then work out where i've actually pressed a fraction of second later, translating it into a swipe etc.
the touchscreen tool in the debug area proves this fact.
WM is perfect.
weirdly, it seems not to occur at all/noticably less using the stylus. maybe something todo with pressure/contact area?
i do think the OP has a valid issue tbh.

Thanks for the info.
First, I didn't mean to mislead anyone. I just noticed increased inquiries about this issue and I wasn't aware of the 99% of users having it perfectly working...is this a fact btw?
Besides, I am aware of the different types of displays but obviously, pinch zoom etc are not exactly the main concern, we are just looking to use the phone with our fingers mate!
I agree - I have been using the phone for many months running WM and I had no issue, whatsoever. I am not much of a techie but you are still referring to the software calibration, correct?
Thanks for sharing some valuable info again. I would love to see those instruction on how to do this calibration as without it and along with much of resentment to use stylus, it pretty much makes the phone running Froyo useless )

But windows mobile typically makes you calibrate your screen when you reflash a ROM, making the calibration specific to your device.
It's also not clear where the calibration info is stored, other than the registry it MAY be stored in E2, or some flash area somewhere. Regardless, it usually forces you to recalibrate (some custom ROMs skip this).
The XDAndroid chaps deemed to 'auto configure' Blackstone calibration for some reason, and this is the most probable reason why folks are having issues.
As for 99%, hummm well, just my releases alone have over 20,000 downloads, and my stuffs one of the lesser used!... yes, some folks have calibration issues, but the majority aren't reporting any... I've maybe seen/heard 20 folks with the issue... that's not too many all in all across all the various releases. AND, some of those guys were also the types of guys saying "this sucks, the battery lasts 2 hours".... as if we didn't all know that ;-)
There was a calibration tool floating around somewhere, plus, those values CAN be edited to suit your device, so there is some home!
Wow, I thought I was one of the only people that had the calibration issue. X_X It's what caused me not to use XDAndroid as much. =(
Anyone have any idea what the calibration tool was? I tried searching calibrate and calibration but no tool was mentioned in the Blackstone droid threads.
PS. I have no idea on how to change the calibration values... =/ When I open up the ts_calibration it shows up as blank. When I open up the startup.txt ("msmts_calib=0x395.0x3c9.0x79.0x77") I do not know exactly what the values affect.
Update:
I tried using the stylus but it currently has the same problem as if I was just using my finger... Does that mean that my touch screen is going out on me? =(
I have a problem too with touch screen calibration.....I guess i'm 1% of users...
im curious as to how maany others have this issue - seems theres a few coming out of the woodwork now
im sure the XDAndroid FAQ or the release thread says the devs are aware of almost all issues so dont bother reporting them (or something to that effect), yet i havent seen anyone mention touchscreen issues upto this thread.
does anyone see a need for a bugtracker for the XDAndroid, or are the forums sufficient? to me, forums seem a bit 'unofficial' with reguard to bugs - maybe an official bug tracker (specific to the android project) would help everyone to see what people are experiencing and numbers involved.
i must say i am only a user, so i dont see or get involved in the development side so maybe this thing already exists in closed circles.
to put it another way, each phone has their own android subforum so it must take the devs alot of time to collate info. bug tracker could be a better way to manage this?
I have the same problem, since 1.6... i touch the screen and is like i touched 1cm outside the screen on the left for 0.001 seconds, so is extremly difficult to type without stylus.
with the stylus is much better but still not good
Ps. i remember the first version of android working on blackstone (1.5 i think) was working good, and the touch screen was fine

I would dig up that version along with calib code in the startup txt file then!
well, i've put the idea forward in the main android subforum here.
it would certainly be useful from a user side perspective to see progress and known issues. fingers crossed

I experience similar issues with 2.2, didn't notice it to the same extent in 2.1. When I type on the on screen keyboard, pretty often i get an added button press detected off to the left (about 2 - 3 cm). The problem does occur a lot less when using the stylus instead of the finger.
This is NOT likely to be a calibration problem, as in that case all presses would be off consistently (e.g. always half a centimeter in the wrong direction or something like that).
It looks as if the Touchscreen sends some "incorrect" data that WM filters as too short of a press or whatever and that is affecting some users.
mmm, questionable.
Calibration is as far as I'm concerned done each time, individually with new system (ROM) unless using a saved one from previous attempt install (my Froyo case).
To my understanding of the matter, wrong calibration doesn't necessarily have to mean your display is "shifted" 2cm to the left or so. Simply, it just doesn't work properly i.e. you have the same problem as all other people in this thread.
Maybe reading TheBrilliantMistake's post about different types of screens earlier would help you understand...
after all, we need that calibration tutorial/tip which is allegedly somewhere around here...

ah - finally
now you got it - this is exact the problem what i want to tell everybody ..., and i'm sure, that this happen, because the touch screen driver doesn't calculate correct the position when a bigger range (like touch from a finger) is touched. This doesn't happen, when stylus is used ...
to remove the first 0,1 sec or something ... don't think, that this would help
...on the other hand ... which module is responsible for touch screen ?
Just for a start the background of calibration (it's on security risks with touchscreen based voting machines but the principle is obviously the same) - http://vote.nist.gov/threats/papers/touchscreencalib.pdf
I believe TheBrilliantMistake in this case thought we'd sometimes hit adjacent buttons. But fact is, it always does trigger to the left and in addition to the correct press being detected, so well there's something else to this one.
Guess it will be ironed out eventually as it's a lot less common in 2.1. But it's annoying to the point of making texting a real pain in 2.2.

does it means, that under 2.1 there is no such kind of "touchscreen bug with finger" ?, because then we can take a look to the modules - maybe we can compare the difference to 2.1 ...
I didn't experience it there but I have to admit that I didn't use 2.1 for too long. Maybe it's a speed issue with 2.1 being more optimized and polished then 2.2 which leads to it occuring on a less frequent basis.
Due to the known problems with powersafe modes not being supported yet in XDAndroid I'm currently mostly running WM6.5 but I'm looking forward to the advancements with XDAndroid, great project.
Add 2 more devices to the 1%.
I'm experience the same issue. My friend which has a newer Blackstone than me let me put my XDAndroid mSD card into his phone and there goes the same issue.
Tested with some drawing applications, here is what i experienced:
Just like others stated before most of the times when the bug occurs I get a line starting like 2 cm to the left of my finger (and a little lower) and ending under my finger. It's like I've been dragging my finger across the screen for 2 cm. Sometimes it goes as far as the left side of the screen.
Since this is inconsistent I doubt it's a calibration issue. I must assume it's the driver. But I might be wrong.
Anyway I believe a lot more people than 1% are experiencing the issue but they aren't posting about it since they believe it's a known issue.
Hey guys, I just picked up my Tegra Note and I'm enjoying it, but in testing out the potential and limitations of the DirectStylus, I came across a problem and I want to find out if it's just my problem, or if it's reproducible with all Tegra Notes with the latest system updates.
Basically, I'm using the stylus, and stylus only mode is activated. This works pretty well and ignores most/all inputs from anything except the tip of the stylus.
However, I have noticed that if I slide my finger onto the screen from the outer edge/bevel, it will often (nearly 100% of the time) register this as a touch. For an example, if I tap the home button with my finger nothing happens, however if I drag my finger from just below the screen onto the home button, it will press. Likewise I cannot scroll through home screens by normally swiping my finger, but if I swipe from off screen on the left or right, it will register. Bringing down the notification area with a finger swipe, etc, all work as well when naturally this should only be possible with the stylus.
The main problem with this is when writing/drawing with my hand resting on the edge of the device. If my palm is entirely off the screen it is fine. If my palm is entirely on the screen then stylus only works, too. However, if in the process of writing my hand slides from the side onto the screen, suddenly the stylus looses focus and I'm drawing lines with my palm.
I hope I have explained this issue correctly, and I wondered if this was a known problem? If there are any solutions? Have I messed up and set an option somewhere I shouldn't have? Should I get it replaced? Sorry for all the questions! :laugh:
Oh and it's not rooted or anything. Just stock, updated to the latest system version through the system updates.
Thanks, hope you can help!
I get a similar issue at the bottom left of the screen sometimes. It only seems to effect the bottom left but in both orientations so that rules out a hardware issue. Doing a quick lock and unlock seems to fix it for me and it functions fine until next time I turn on stylus mode. Seems hit and miss with no real way to replicate it.
It didn't seem to do it before ota 2.3 so I predict a hotfix for the issue. Its a minor issue, the battery life on 4.4.2 isn't however, 4-5hrs with lite use is pretty rubbish. I suspect that's an issue with the power saving features (I think it's stuck on Max performance all the time).
Would be nice if they fix the SD write issue but Google dictate that I think.
Mine was certainly a lot worse than that - persistent on all four edges of the screen and there is no way to stop it. 60-80% of the time it was manageable, but consistently reproducible, other times it was far worse and could only manage dots and dashes when I tried to write anything while resting my palm on the screen. It also developed a 'blind spot' problem I've noticed reported on a couple of forums - a spot where the stlus simply refused to draw - so I grew more concerned that I had a problem with the actual hardware. So, I took it into the store I bought it from, and they're going to replace it for me.
Hopefully I won't have a problem with the replacement one, because I absolutely love the tablet!
I've had similar problems... just remember, all of the stylus functionality is governed by software; the screen on this is simply a regular capacitive screen that's also capable of detecting the size and shape of what's touching it, and the rest is calculated by software. It's a neat idea, but in practice it hasn't held up as well as Nvidia would've liked us to believe. Now that I've had a Galaxy Note 2 for a couple months, I have to say that the active stylus experience blows the TN7 away, but then again it's a much more expensive technology to implement. I almost always used a pencil with my TN7 while it was my day-to-day work buddy since I found the stylus to be too sticky and hard to write with... I also found several of the issues I was having weren't as bad while using a pencil, so maybe you could give that a try. Also, remember that if the screen is dirty that it will affect the stylus's performance as the screen is so sensitive that even a little moisture could register as a touch on the screen.
I received my replacement tablet today, and it is a lot better than the one I previously had. While the problem is still there, it is far, FAR better than before. Now it seems to be a minor nuisance, rather than a consistently reproducible problem. On top of that it has a much more vibrant screen - less yellow and washed out - and no 'dead zones' when trying to write with the stylus. So while I am certain software has an impact on performance, there must have been something weird going on inside the hardware of my previous device, too.
Considering the price, the fact that others have had similar issues, and how much I like about everything else - I'm very happy with my new TN7 now!
Have same problem .... When i swipe from left or right side of the screen it detects stylus nd do all the things.... Dont knw wat to do amazon is not replacing too the tablet..!
Same problem, I don't usually mind it other when I'm using an app like sketchbook pro, it becomes really annoying.

I have a UK Advent Vega Tetra Note 7 (the Currys /PC World version) with a slide cover. Lately the touchscreen has been exhibiting a few intermittent problems. The most annoying is that when I hit a soft key or type a letter, the screen registers multiple touches. This is extremely frustrating when I hit the back button, only to close the entire application.
The pinch and zoom sometimes plays up to. I thought that might be related to the already-identified issue over the black area to the sides of the screen being touch sensitive when they really should not be. It means that your palm often inadvertently acts as a second finger when scrolling, and zooms the screen. However the problem seems deeper, as it can happen even when being careful not to touch the bezel. And if you hold the black area off to the side of the screen, it brings up a menu.
When browsing, occasionally the touch and hold works a bit randomly, for example, when you hold a link that you want to bring up in a new tab.
I have factory reset the tablet and the problem disappears, only to reappear later. And it isn't constant either - it comes and goes.
I wonder if the issue has something to do with the magnetic slide case? Or do users without the case also experience problems? It really is a pity, as this is a great tablet otherwise.
I've had issues similar. After going back to 4.3 they seemed to go away (battery life was better too). Now back on 4.4.2 and OTA 2.3 the problems are there again. It must be a software issue, hopefully it'll be fixed along with the battery life issues.
Roll on 4.5 and let's hope nvidia give us it.
downgrade?

How did you downgrade? Is it just a case of a factory reset, then declining any upgrades?
I do hope Nvidia are aware of this problem. It really takes the shine of a good tablet.

Look here for an Advent guide to reflashing the 4.3 ROM:

You can ignore the updates afterwards. By no means though is 4.3 perfect, there is problems with the GPS and various other things that have been fixed in the latest versions.
Personally I found the latest to be best overall - Minus the battery life issues and some minor stylus/touchscreen issues.
Thank you BuToNz. I developed touchscreen problems when using the stylus after updating to 4.4.2, sensitivity was lost in an area the size of a large coin, if it registered anything in this zone it was just a messed up line. I downgraded as per the link details to 4.3 and the touchscreen with stylus is fine again.. Left feedback with Nvidia, hopefully they can repair this.

tegra note touch faulty
me 2 facing the same problem pls help..
There is a known issue that has existed since the tablet was launched where sometimes if you wake the screen by opening the cover, the touchscreen can become erratic or unresponsive. If you do a quick sleep/wake with the power button, it usually fixes it. Why Nvidia hasn't been able to fix this after a year is baffling and part of why I held off on getting a Shield Tab (among other reasons).

This has been consistent with mine and I can live with it, however recently randomly after a day or two of use, if I turn off the tab with the power button and have it charging, when I go to use it again after a random time, I get a completely unresponsive touchscreen after powering it back up with the button. No response from the screen at all. Buttons work fine, and a hard power down fixes the issue just fine, but no amount of play with either the power button or screen cover or even stylus fixes the non responsive screen. Very strange.
Still love every bit of this tab, but do hope for a Android 5.0 update soon for both it and my Shield Portable.
