Hi everyone.
I've copied my post from Lenovo forum to show you that Pen Only mode at OS level is very necessary for people who write with their pen on Thinkpad .
and now, Since the root is achieved, I want to know that is there any chance for a developer to do such tweak ?

Hello Everyone, this is a proof that why we need a Pen Only mode for the whole system . yes, since our tablet has digitizer, there should be an option to work with the tablet with just our pen . An option to disable the touch layer entirely so we can write like a human being ! ( apart from hitting the bars and activate menus )
just download the video that shows everything :
http://www.mediafire.com/?snoh86t9drdiw8w
As you can see, writing is a hard thing to do without any cloth under my hand or gloves on .As I demonstrated, each time this problem occurs, It will be gone entirely by puting something under my palm . and it wont happen 99 percents when I write completely on a cloth.
To Development Team : Please fix this problem, Pen is the only advantage of your product .
pressing and holding one of the physical keys would be a nice choice for activate/deactivate it . so people who has not pen, could deal with it .
I've gathered some other post related to this matter :

I write all of my university courses in TPT and Ive been examining this issue every day. though this problem does not depend on the palm entirely , inking failure lowers to a really small percentage when you do not put your palm on the screen . for example I want to write PEN in a random coordinate of screen in a random part of random sentence . I stroke my pen down and move my hand to write the PEN down . it writes "P" and "N" very good but instead of "E", I can see nothing or in the best condition it writes only a dot --> "P. N" or "P N" Even though that IS a problem, It wouldnt if I could correct it. unfortunatley that certain area will be deactivate for a random amount of time . you can not write ANYTHING in that area during that time. not a single line . it will work nicely if you write a line from outside of that unspecific area into that area ! this shows theres no problem of inking in that position . and the funny thing is someother day this area had no problem and maybe tomorrow will be ok too even next page will be ok . imagin how hard it would be that random area, in a complex formula ! you will lose important amount of time to deal with tha mess. now palm thing comes in the story from this sequence; remember that unknown duration of time that you could not ink anything in that area ? well, if you put a cloth under your palm, it works so much better . Lenovo, too many people are losing trace of notes, too many disappointments just for this . how hard is it for your team to roll an update to add an option for turning the touch input off ? holding harware rotation key would be awesome choice

I have the same problem with my Thinkpad Tablet. It doesn't matter which app I use. I don't use any screen protector. As I have been enjoying the comfort of a stylus on a windows tablet before and was looking forward to move away from Microsoft with this tablet, I'm really disappointed to find, that the stylus I not usefull at all beeing that unresponsive. So please fix this issue as fast as possible or I will have to switch back to windows again!

I was taking notes during a seminar last week and noticed that on the bundled Notes App, there were certain areas of the screen (middle left) where the pen just wouldnt respond at times. I would try a few times and then it would finally take the input, wondering if anyone else is having similar issues. I downloaded the WritePad application and it seems to be better there, also downladed Quill and saw that it was having similar issues so I'm wondering if its app related or hardware related. I'd love for the pen to start inking immediately as I start drawing, not start well after the stroke has begun.
Also note I have installed the Military Shield on the ThinkPad so not sure if this might have something to do with it also.

I've seen the same thing (for me - a right hander - it normally shows up on the middle right side of the screen). To me it seems like the palm rejection in the note app is the problem.
I was able to get around this by placing a small cloth (the one I use for wiping the screen) under the heel of my hand while writing... since it is a capacitive screen, the cloth hides the palm and seems to make the pen behave better.
yahoowizard wrote:
I'm not sure if I have the same problem, but is it when you keep writing and suddenly, there are moments when nothing happens when you tap the pen, sometimes at a specific region? Over the past week or so, I've used the Writepad application for about 4 hours a day or so and what happens is, a while after writing, a region starts being a bit unresponsive. Either I keep tapping random buttons on the side or I try to make a stroke outside that region, then try to immediately write in the region I'm actually trying to write in. Locking the tablet, then unlocking it fixes the problem, but it's still annoying as it starts back up again in 10 minutes or some random time later.
===========================================================
I agree. I am an artist and the dual screen sensor does get in the way of my art. I can manage, but would highly appreciate if it were able to switch on and off the compacitive touch function on demand.

Hej,
the touchscreen of my O2 XDA Neo is dead... most of the time. After a long time (i.e. can't be told exactly) not using it, it works for a few strokes, so I can get the phone to run. Rapidly it changes then, first the right half of the screen ceases to work (nearly exactly the right half, fiddling with notes or align screen shows that), soon the whole screen doesn't react. Some time later it may work again.
Some of the software can be used by using only the navigation buttons, lot of the software (including dialing arbitrary numbers) can't.
Is there any way out? As the warranty is void, I don't hesitate to open the device, if it may help. But I guess it is not as simple as increasing or decreasing the pressure on the screens edges...
Or is there any input software that uses the navigation keys? The standard soft keyboard can't be used this way, the other additional keyboards I found surfing the net don't have this possibility too. (Is there a board here to ask for software for a specific OS? Or where is a good playce to do this?)
Thanks
Inmare
In short, sometimes it's working and sometimes it's not?
Maybe there is a loose connection somewhere? Although I'm afraid it won't be that easy, but who knows. Guess a touchscreen is quite a delicate piece of electronics.
I'm afraid I don't know any software for typing and stuff and using the keyboard with your keys etc.
It does for for some (short) time, then ceases to work - sometimes at once, sometimes slowly (first the right half, after some time the left).
I don't expect to be able to repair a defective touchscreen; I hope it's just a loose connector or such... this device uses star shaped screws smaller than grade 9, I have to get appropriate tools tomorrow (i.e. today as it is past 12pm... so yesterday is today too... so I already bought the tools yesterday? I need a digital diary again to keep track of this ). Lets see if I can get the device to be reliable again.
The digitizers are sold on eBay (example) for not much. Not sure how to install them tho.
Interesting. At least I now know the size of the screwdriver. And I see the connector... I think it is worth the try.
Here you can see the inside of the device. Looks like the digitizer and the display are packed together within a metal case, but maybe it is just the connector. Otherwise I will have to open this too.
I think I will do this in the far future. Next year
Thank you.
Hi Inmare,
is there any improvement
because I have the same problem with my jamin
what should I do?
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, Just wonder if you still have the screen problem (register the wrong place when click) after the upgrade.
No. You should check out the humongous thread on google support forums. Googe have now abandned even giving updates on this serious problem.
http://www.google.com/support/forum...8e&hl=en&fid=04134c63c784258e00047fdfe09ae547
p.s. no fix in ere36b either (as im running that now and still experience this problem at random)
I don't understand this issue, I just don't see it on mine at all, no matter what ROM I install ... there has to be something more to this than a simple fault across all handsets ... either select faulty ones or some other factor. Mine just works 100% as expected at all times.
That said I have had no 3G issues either, no matter what radio version I use. Perhaps I am lucky ?
I think its because people are touching the edge of the screen while pressing with the other causing it to register incorrectly

That is not it, there are plenty of videos that show the touchsreen misfiring while just laying on the table. Also, the way I hold my phone I am never touching the glass surface other than with the one finger doing the touching.
With regards to some people not seeing it, this issue is very random. I can go for days without noticing it and then out of the blue it would come back, most annoying when it happens while typing something.
There is another somewhat related issue with the sensor on the n1. If you download an app called multi touch paint and try to draw two parallel lines simultaneously from say top left corner down to bottom right you will see that the lines are not straight at all and full of zigzags. Only way that this sensor recognizes multiple lines properly is if you draw perfectly vertical or horizontal lines.
There is also a discussion on developer groups where game developers are pointing out this very problem of multi toch totally being screwed up where it switches axis causing your touch to register in completely the wrong place. From the comments of the android engineer it makes it seem that the sensor hardware is just like that, cheap and low quality.

I know, I have seen all these videos and attempted to re-create many times to test I have never seen this issue once.
Don't get me wrong I can understand it being a mare of you are having it, but I just dont ever see it.
after trolling the Google thread, it seems to me there are several scenarios everyone is lumping into "screen issues" and it's going to be hard to pin it down to one source
Mine happens (touch registers on the wrong part of the screen) when I am using certain apps (Ringdroid, Browser mostly) - a couple of things clears it up ; press the sleep button, kill all tasks if you have an app for it, or change to landscape mode. For other people it's the soft keys and/or much worse. Since mine clears up with a specific action, I tend to think it is software related.
With mine it used randomly to happen but only in the Launcher (never again since 36B). I couldn't point anywhere but if I selected any app with the trackball and opend ist everything worked fine again, also the keyboard on the launcher worked well. For me it seems that it has something to do with the launcher.
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
edit: and when did i move to 'Senior member'!!?
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.
