S-Pen sensitivity - can devs change this - AT&T Samsung Galaxy Note I717

I don't know if this is allowed in this section, but I am specifically curious with a question regarding development of a calibration app for the s-pen. I'm wondering if this is something that devs *can* do, or if this is not possible (for whatever reason).
I really hope it is, and that we can get something going. I have to depress the nib on my s-pen more than I would like in order for it to register. It's not bad, but I would prefer it more sensitive such that just the weight of the pen itself was enough to register.
I believe such a calibraiton app is possible, because even though my pen takes a bit of depression to get it to register, I know it is "activated" by the phone well before it even touches the surface of the screen. I have seen times where the pen does not register actual "touches" or "clicks", yet does interact with the phone, which leads me to believe that the pen is actually recognized by the device at a bit of distance before touching, but doesn't actually "click" or actively perform like your finger until the nib is physically depressed beyond the calibration point.
If we could just change a setting that essentially says "this is where the nib zero point is", and change it to suit our needs, and our individual pens, that would be AWESOME. One other thought, though, is that it may not be possible to achieve what I'm thinking, if there is no "signal strength" (for lack of a better term) as the pen gets first recognized and then closer to the screen. If the pen is reporting "0 nib press" until it is actually physically depressed a bit, and the "signal strength" can't be used as another calibration factor to allow it to simulate touches and clicks when it's just "close enough", then maybe it's not possible after all? I'm thinking something can be done, but I guess I'm not 100% certain.
If you want to see what I'm talking about where your pen is recognized by the device, but doesn't "click" or anything, just let the screen timeout from not touching it (while it's on). When it first dims, to warn you that it's about to turn off, just hover your pen near, but don't touch the surface. You'll see that it wakes it back up. Yet I've never had my pen EVER "click" or interact with the device from this distance, and it ALWAYS requires the nib to be pressed.
This post is meant to serve as food for thought and proof that the sensitivity should be more than enough, but there is just some calibration setting that is prevent the pen from being more (or less) sensitive.

You post in this section if you are personally developing something.
And yes, I would also be interested in some sort of calibration tool. It's a shame Samsung didn't include one.

this definitely should've been posted in the q&a section or the general section, not here, this is the development section , please move or delete!

Sorry. I was hoping the detail of the pen activating when near the screen might be a light bulb to some devs who view this forum. Thought it was a relevant "development" detail, didn't want it to go overlooked in the general section.
Mods, please move the thread if appropriate.

I'm testing TouchScreenTune for the developer Vitalijus, and found that Da_G's OC kernel is missing KALLSYMS (TouchScreenTune requires it), i assume this means ATNT stock is also missing it.
I PMed Da_G to see he can plug it in, hopefully he can and our calibration problems will be solved.
From my understanding all that is needed is to set CONFIG_KALLSYMS=y CONFIG_KALLSYMS_ALL=y in the kernel.

My pen doesn't reach all the way to the edge of the screen on 2 sides of the screen, is that normal (or typical)?

Yes, many people are having this problem with the bottom(about .3mm) and right(about .01) side. They have not aligned the SPEN correctly to the borders of the screen.
Hopefully they fix this soon...

Hi,
I added in the requested KALLSYMs support.
If it can be determined that there is a fixed offset common among devices, this can be fixed at the kernel level.

i noticed when you change the spen settings from right to left handed the sides of the screen where you cant get to the edge changes as well, but the bottom is the same on both

Started using toucscreen tune and it almost completely fixed it.

Transformer is more of a gobot

i'm really, really enjoying this tf201+dock. the battery life is sick. the cpu is a beast that hauls on exynos 4210, and that was the hottest ARM SoC ever. it's running the best android software available for a tablet right now, which is seriously underrated. it's the best dedicated gmail and gtalk clients available, it's got one of the fastest and most compliant mobile browsers for any tablet. it's easily rootable. and holy crap did i mention it has a real keyboard.
so yeah, this will get pried out of my dead hands, or tossed whenever the real transformer comes out.. whichever comes first. i can't wait to ditch this if the real deal ever actually hits, because this one is just the cheap gobot knockoff of what a dockable android tablet should be.
how is it a knockoff? go look at the exacto thread, or the vulcan pinch poll, or any of the numerous "none of this crap works, is that normal?" threads we enjoyed for the first 6 weeks of the tf201s release. these units are stitched together like the $40 "louis vuitton" bags sold on lexington avenue with upside-down "L"s.
i'm "lucky" because my unit doesn't have the big problems, but even a "perfect" tf201 is a near-constant reminder of what this product would be if it was made by the right company. i noticed one of the reviews posted here made the point that "the ipad2 wins in having better power and volume buttons". who the hell cares about power buttons? what matters is tegra3, right? well, it turns out that the power and volume buttons on the tf201 suck. they're hard to feel for, hard to press. and then you realize there is no "wake up" key on the keyboard. (please, someone make my day and tell me a secret key combo to wake up the tablet screen.) but there isn't, so you find yourself looking for that little power nub over, and over again, until asus punishes you into knowing intimately how bad of a power button you have and f*ck you for buying it.
and i think it all really just boils down to this being asus, a company with an already long history of ripping off other taiwanese manufacturers (hello, gigabyte) and trying to differentiate by dressing it up with lipstick and trademarked BIOS features. i bet asus engineers were saddened when they learned there was no centerpiece HEATSINK to decorate on the tf201. asus does not slave over the perfection of products and release them with an id-style, "when it's done" pomp. asus hammers out products like M&Ms, spraying the public with buckshot and knowing that some will hit. there is literally zero history of any fundamental innovation coming from this company until the tf101. the first detachable/dockable android tablet with battery in dock. how did that happen? because lenovo is making theirs after, not before asus. was it an accident? mistake?
now imagine a world where transformers the toys, the tv show, the awesome 80s movie with that weird-al yankovic song, all of it never existed. and then along came GOBOTS. well, they'd be pretty cool. and you'd play with them. until the real transformers came out, and optimus prime's head transformed into another robot that punched leader-1 in the face.

Uncheck MobileDock Battery saving mode in Asus Customized settings
This will drain more power when asleep though
The Transformer Prime is more of a Megazord.
Ahh, another hater. There are plenty of web-sites for you to sell your gobot and buy an iPad.
There is a unlock button on the keyboard dock atard.
Really, what would that button on the top right do?

the top right button puts the tablet to sleep (and locks it if you use a lock). that's why that picture of the lock is closed.
for keyboard wakeup it appears there are two modes: either none of the keys wake it up, or all of the keys wake it up. as a previous commenter mentioned this is defined by the "MobileDock battery saving mode" setting, which you obviously have enabled as this allowed you to rationalize that a closed padlock means "unlock".
there isn't much reason why asus couldn't have made an unlock key, or at least not a very good one. the dock has its own battery. a key could have been wired to turn on its power while in battery save mode, just like every laptop ever.
i hate to troll but....
you dont like? Why dont you just try if it will blend then... ?
I typically refrain from contributing to pathetic rants and crybaby posts because ultimately all they want is the attention from these kinds of posts. And responding to their over indulged tantrum in either a logical response or sarcastic whip only results in an escalating flaming contest. But I'm just sick of coming to this forum for useful information and only seeing another copy an paste complaint from one of the other hundred waisted space posts.
My TFP is the best f**KING super computer I have ever owned. combined with the dock, I can do things I never thought possible from an android OS. It has become my laptop allowing me remote access to the rest of my environment, my media center, my entry point to the digital world, a video phone for long distant family, and it functions in a hundred other ways that has improved my life. It's the damn swiss army knife of tablets.
For all who read this, I'm on XDA to better myself by learning how to use and improve the technology I own. I'm not hear to "listen" to you whine. If you're not part of the solution, you're part of the problem.
Go somewhere else to have your pity-party. Leave XDA for useful contributors and those looking to learn.

Well, with Honeycomb that was indeed true, but with ICS I also could unlock my Prime with it?
When my Tablet is attached to the dock I lock it with the upper right key. To unlock it, I slide over the touchpad, screen goes on and then press the "lock"-key to get to my homescreen.
Battery saving Mode is on I guess, because waking it up with keys don't work.
I don't know, but is that your problem?

this is interesting because my touchpad definitely isn't waking up the tablet, with or without the battery saving mode enabled.
are you running HC or ICS? and out of curiosity, what is your MobileDock version in Settings > About tablet? mine is TF201-DOCK-0206.
@OP u just wasted precious time of my life of which I could never get back for this and I normally don't respond to BS posts, however sell your prime since u ain't man enough to handle, buy an ipad 2 or better yet a fijutsu tablet and then most importantly turn it gps on and go play in traffic in a major highway near u.

Hmm. Which is worse? Those starting new threads to discuss issues already documented?

screen responds to spen when not touching screen?

Anyone else having this issue? My spen will launch an app or type characters on the keyboard even when its 1/2 inch away from the screen.. Getting pretty frustrating. I see there's no ability to calibrate the spen either.
There is a way to calibrate the S-Pen over on the international note forum, haven't heard of anyone trying it here. Check it out n let us know if it works, I would but I can't have a note for another 3 months :c
International forum? I heard those guys are pretty rough.. Lol thanks for the tip!

The spen "phantom" triggers the bottom right of my screen when using it while I'm lying on my back. It irritates the hell out of me.
I think it has to do with the combination of a faulty spen (the nib pushes on the pressure sensor when the pen is inverted) and a poorly calibrated screen.
Sent from my SAMSUNG-SGH-I717 using XDA App
Personally, mine doesn't trigger easily enough for my taste. I have to push harder than I'd like to get it to register. Not "hard" per se, but hard enough that the pen almost wants to 'skip' instead of 'slide' across the screen when trying to navigate around. (Talking about the minimum pressure needed to engage swiping and touching, etc). Still completely usable, just wish that it was a wee bit more sensitive so I could just 'glide' the pen around lightly vs pushing it down while moving around.
I'm having the same problem. I just noticed it last night. I was using the s-pen and would get about 1/4" to the screen and it would select apps/options whatever. Kinda annoying

Yes, I reported the same issue yesterday... http://forum.xda-developers.com/showthread.php?t=1511230
After exchanging my first Note, the second has the same problem, but over a smaller area. Unfortunately the area affected this time includes part of the keyboard and the bottom row of the launcher screen, so it makes life difficult when using the S Pen. I'll be exchanging this one too.
Anyone interested can check their device with the S Memo app. Just open a new memo and start waving the S pen over the screen surface about 1/4" above the screen. If you get brush marks on the screen without touching it I'd say there's a problem. And by doing this over the entire screen you can map the areas affected.
If you search YouTube for 'samsung galaxy note s pen problem' you'll find at least 4 international users who've posted videos on this problem.
I'm no expert, but I've experimented with other Wacom pens (I have two older tablet PCs), and neither of those pens exhibit this issue when used on the Note. It seems they only transmit when the pen nib is depressed. The S Pens transmit all the time... there doesn't seem to be a switch depressed by the nib. This system actually provides more sensitivity, such as scrolling screens with less pressure than required with the legacy Wacom pens. However, this increased sensitivity requires a perfectly calibrated digitizer over the entire screen to sense when the pen makes contact with the screen and I'm guessing that's where my problems are coming from. Hopefully the third time's the charm for me.

With the nub touching the screen, but applying no pressure, I moved it all around a new memo and didn't get any brush strokes. Is that a good test?
Yes, that's sounds good to me. That's the way my Note works with my older Wacom pens.

I think OP's pen is defective. When I press the tip of the pen inward (toward the pen) with my finger and hover over the screen, I get the behavior described - I can be 1/2" away from the screen and tap/draw. But if I don't press the tip of the pen, I have to touch the screen to register a tap. There is a very tiny amount of movement in the white nib, and it should be on a slight spring. Mine doesn't activate upside down either. Maybe someone jammed your pen into something and broke it?

You're right... I get the same behavior by pressing the nib anywhere over the screen. However, on these defective devices the S Pen still activates the screen in certain areas even without pressing the nib. So I think the pens are probably working okay and it's the digitizer that has problems.
That's my point - the nib is probably broken in a permanently "pressed-in" state. I would suspect the tiny moving-part spring action of the pen before I'd suspect the solid-state digitizer.
AT&T has the spare pen and larger holder for $30, which is a deal considering they offer the spare pen alone for the same price, and Samsung sells the combo for $60. Or you could take it to a store and test the store pen (though based on my experience that would be more likely to be broken or stolen).

Maybe this picture of a test memo will clarify the issue with my second Note. The S Pen never was close to the screen, at least 1/4" away. But the area of the defect is limited to just a small portion of the screen. So in this case it's not likely to be a permanently depressed nib, but a bad portion of the screen. I can't say what the OP's issue might be. (On my first Note, the bad area was larger and near the top of the screen.)

Edit: I suspect there's probably some of both out there (bad pens and bad screens)... either way it makes the device difficult to use with the pen and worthy of an exchange.

Maybe I exaggerated it a bit. What I would *like* is if the pressure of the pen's own weight was enough to make it work, and I didn't have to physically press down at all to help it. That way I could very lightly glide it around without pressing much if at all. Basically like your fingers -- you really don't need to press down at all and I want to use the pen as a more accurate finger. But I just need to press a bit. Enough that sometimes I don't press enough and get frustrated that I need to re-swipe or re-tap, and it makes me not really want to keep using it lol. I don't need to like lean on it or anything... it requires about as much as you'd need to make a bic pen start to write on paper.
Well, just back from Best Buy. I was lucky because they had just received another shipment of Notes. I did another exchange and my third Note is working great! No problems with the pen/digitizer combination at all (so far).
While at BB I tried the new pen on my old device and found some improvement, but could still get some spurious screen actions in the lower right corner where the digitizer needs calibration. As other posters have noted, it seems worse if you hold the device upside down (maybe due to the pen nib switch), but was still wonky at any angle.
So it looks to me like this issue may sometimes be due to a miscalibrated or defective S Pen, sometimes a miscalibrated or defective digitizer screen, and sometimes a combination of both. I'm just happy to now have a working device.

I'm having the same issue...I have to press harder then I'd like. We cannot be the only ones that think like this right? I would like the pen to work under its own weight.
So the question is. How sensitive is your spen guys? I'd like to make sure there is no problem with my phone or spen.

As other posters have noted, it seems worse if you hold the device upside down (maybe due to the pen nib switch), but was still wonky at any angle.
So it looks to me like this issue may sometimes be due to a miscalibrated or defective S Pen, sometimes a miscalibrated or defective digitizer screen, and sometimes a combination of both. I'm just happy to now have a working device.

Glad to hear that BB is working with you. My phone and pens (the pen that came with the phone, as well as the pen that came with the "s pen holder" accessory) both display the same symptoms while I'm using the pen at an upwards angle. My s memo test was much worse, as the screen starts acknowledging the s pen well above the picture above. It's super frustrating, and I'm glad to hear that not all phones are like this. I'll definitely be exchanging my phone when I have a few hours of free time.

Sorry, I guess I should have updated this thread. My third Note started exhibiting the same issue after about six hours of use, although it was still better than my first two. I also checked the display models at my AT&T store and they showed the same issue, so all five Notes I've had contact with all have shown the same defect.
My solution was found in another thread: http://forum.xda-developers.com/showthread.php?t=1517411
In post #22 of that thread was my final fix, which is still working great for me at this point.

AT&T Samsung Galaxy Note MAJOR ISSUE with Stylus!

Okay basically of all the Notes I've used (5 of them!) they all have this issue where towards the bottom of the screen where the "." and "Space" key are on the Samsung Keyboard, if the stylus or phone is being held in a certain way it will think it's being pressed down when it's not actually, but it only happens in that one spot! I took my AT&T Galaxy Note back to the AT&T store today and both display models had this issue, the replacement phone they gave me had this issue, and one of the Employee's had a Note that also had this issue, all in the EXACT same spot! I just want to make everyone aware of this and to see if this is an issue with all AT&T Samsung Galaxy Notes, and if it is make Samsung and AT&T aware of it and get them to issue a software or hardware fix.
Thanks.

(Interesting enough all of my Wacom Tablet PC pens do not display this problem with the Note)
Update: When you test to see if your Note does this, make sure it's leaning in towards you a bit
I fail to see how this is a MAJOR issue? What problem would this cause?

Because you can be sitting there using hand writing recognition or typing with the keyboard and it suddenly randomly starts hitting a bunch of keys, or drawing something and it just randomly starts scribbling. It's annoying as hell! also the fact it affects EVERY note I've touched.
i have gt n7000.no problems here.prob. just a software bug.hopefully they will update firmware to fix all these small issue u guys having.
Glad I'm not the only one with this problem. Mine is affected at the lower right side of the screen. I hate it when it's pushing buttons.
I had hoped that replacing the stylus would resolve the issue but I'm having doubts after OP's post.
I would consider this a major issue.

I just tried replicating this on my note. Doesn't happen.
Sent from the best mobile device ever --Samsung Galaxy Note
mine works fine.
Also, I fail to see this as a MAJOR issue...maybe an annoyance but Major?
I believe what Wolfox360 commented on my video is true, I think it's magnetic interference from either one of the radios or the speaker causing this, that's why my Wacom Tablet PC pens didn't do this, they're shielded better, I say this needs a hardware fix from Samsung for new Styluses that are shielded better.
Yes, I agree this is a valid issue. There's at least two other threads in this section on this:
http://forum.xda-developers.com/showthread.php?t=1512578 &
http://forum.xda-developers.com/showthread.php?t=1511230.
At post 14 of the first link I provided a pic of a test memo where I mapped the area of the screen affected.
My first Note's defect was not limited to just the lower right corner... it was pretty wideapread. My second Note's defect was limited to the lower right corner but it didn't require the S Pen to be tilted horizontally or upside down to draw on the screen or start going crazy on the keyboard. My third Note only has the issue in the same location (lower right corner) and only when the S Pen is horizontal or tilted back slightly (like using it while laying in bed or in a reclining chair). I've concluded the S Pen is definitely involved (it doesn't happen with my two Wacom tablet PC pens), and the fact that it is often restricted to the lower right corner must mean the digitizer might also be a factor. Something in the pen is causing an increased transmission when it goes horizontal or becomes inverted.
As the third device is at least usable I've decided to keep it and hope Samsung comes out with an improved S Pen or some other fix for the device. In the meantime, I just try to keep the S Pen upright when I'm using it. I guess I probably use the S Pen more than most folks because I'm a long time user of Pocket PCs and Tablet PCs.
The Note is in all other respects my dream device. I'm a fan!
I don't have this issue, whatsoever. Mine works fine. In fact, but my AT&T version and my International version work perfectly. I can drag the tip across the screen, just barely touching, and it won't register anywhere. Then I increase the pressure just a tiny bit and it does register. Operation is uniform across the entire screen.
mine doesn't have that issue at all
As "Wolfox360" showed on his youtube video http://www.youtube.com/watch?v=tPqGw297Fa0 putting a thin ring of Aluminum tape around the stylus almost completely fixes this issue.

Yes, the aluminum tape around the S Pen seems to fix this issue for me. It's not easy to get the placement and width of the tape just right... and it may differ from pen to pen. I ended up with a slightly narrower band of tape (4mm rather than Wolfox360's recommendation of 5mm) and centered on the bottom of the button, with 2mm of tape over the button and 2mm extending below the button. When I used a tape width of 5mm I was losing some pen functionality (areas of dead spots on the screen).
I wish Samsung and AT&T would address this issue and provide modified pens to those users that need them.

I hope they do too, this is my first Samsung phone since an old BlackJack II from several years ago and honestly I'm a bit disappointed with it so far, even my HTC Desire Z (T-Mobile G2)s seemed of all around better quality than this.
My Note has this issue too. Whenever I hold the s-pen near the bottom right it acts like it's touching but it isn't.
My theory on what's causing the issue in the first place is the fact that there's a speaker on the rear of the device right where we seem to be having the issue at. Maybe the speaker magnet there is what's causing it to go wonky?
Glad to see that a simple fix like the aluminum tape is available, gonna have to try that in a bit. I'm thinking that this supports the idea of the speaker causing the issue though, since just adding a tiny little bit of foil to shield the s-pen from the speaker can fix it.
I have the white att galaxy note and I do not have this issue...I've tested numerous times.
this phone is what you get when a skyrocket and galaxy tab get together and make babies - galaxy note!
White AT&T Note here and don't have the issue either, although, even if I did, I don't know that I would define that as a "MAJOR ISSUE" seeing as how you have to hold the pen a certain way in a certain spot to even get it to do it. Seems more like a minor nuisance.
So is this happening to the black note only? Weird if it is the color shouldn't make a difference...people who are having the problem should post the color of their note.

Mine is the black model and has the same issue. In most cases it is probably more nuisance than problem but when trying to use the note application it becomes a real problem for me.

I stopped by the local AT&T store and confirmed this issue exists on the white Note on display, just like the black one. The S Pen holder didn't help either... still the same.
I've had 3 black AT&T Notes with various levels of this defect.

Side of Screen dead space

Ok so i have had this phone since it came out. I love it however i feel there is some dead space on all sides of the screen. Its not always there but its there a lot. It gets me killed in games and makes dragging from one screen to another difficult. Do others feel the same. I will post a picture of it in action in a minute using the developer options.
Here it is. Notice the side of the screen not getting input.

Ye I was messen with the dev option the other nite n noticed I feel jipped....not really sxreens big enuff as is
Yeah that is very easy to see when you enable the touch locations in debugging.
Hmm. Dunno. At first I thought it was my case getting in the way but nope it's definitely not that. Just dead zone.
I played with the dev options touch tracks. If you are swiping the pen onto the screen it looks like there is a slight delay, but if I draw lines from the center out at all angles it seems to take me all the way to the edge most of the time. I saw one or two tracks that didn't make it, but then when I'd draw in the same area it would hit the edge. (If it really drives you insane, go back to bone stock and see if it duplicates. If it does, I'd get a new phone under warranty if you have that option) The gaps that you are seeing are WAY bigger than the gaps I had when they appeared, which was only a few swipes out of many.

Why not take a screenshot to prove yourself? You make it sound like you are experiencing no gap at all, which I find hard to believe.
But please if you can back this up with screenshots it would be greatly appreciated and help figure out if this is really a problem or if we're making it a problem when there's none there.
Don't have this problem, but I do have the problem of not being able to draw straight lines from top to bottom on the right edge of my screen.
Even if I use a straight edge with the S-Pen, it draws a squigly line, but ONLY on the right side of my screen. No where else.
This is a replacement phone btw, the first one would lock up if you put more then 4 fingers on the screen, and I had a dead spot in the bottom right corner of my screen.
Stock has that visual touch option?

No gap confirmed and proven.
Seems to be fine on the newest build of 4.1.2: http://i.imgur.com/sIxDBMW.png
Adrynalyne and illogic6 can you guys confirm you took those screenshots while using the S Pen to see touches? Here's why I ask.
These first 2 screenshots are of me using my fingers for touch input.
Now these next 2 screenshots are using the S Pen.
If you look you will see that when using your fingers the Pressure sensor always reports a 1.0 maximum pressure, and using the S Pen it is able to have a large range, with 1.0 requiring a great deal of force. Since neither of you guys have a solid red 1.0 for Pres I am going to guarantee you both used the S Pen. In this case, as you can also see in my screenshots I was able to get basically full range of the screen and digitizer when using the Pen. Unfortunately that's not the issue we're having, it's with finger touch.
The closest I can get to any of the 4 edges using my fingers is within 20 pixels reach to the very border. If you guys could please re-do the tests and screenshots using your fingers instead of the S Pen I'd really appreciate it. Thanks.
Mine were both done with the s-pen.
However unlike the pen, your finger ends up going off the screen when it ends up losing touch.
I think that's the reason we are seeing this. The finger cannot be as precise as the pen.

I know they were, and thank you for confirming. I'd like to see some shots from you and illogic of you guys using your fingers instead while doing the same motions.
You caught me editing my post. Check it again to see what my theory is.
This would be better tested using a capacitive stylus.
Also despite the pointer location cutting off, I can actually press in the area that appears dead and activate menu options.
So something weird is going on for sure but I don't think they are truly dead spots.
Here's a screen shot, looks like it does cut off touches before the edge of the screen with the fingers. I Wonder if it cuts off when the first part of your finger leaves the screen? Maybe It senses bezel input and registers a swipe? All of the inputs along the edge are spen inputs.

I agree. Especially when I watch full screen flash videos the little tiny bar on the bottom of the screen along the left edge, I am able to press a button probably 10x10 pixels square right on the edge and it almost always works the first time. And that's using my finger, with the Pen it's obviously always accurate.
I wonder why it shows up like that though? The show pointer locations developer option is as raw as you're going to get at visualizing how the hardware is being interpreted, so it's not like other software could read those dead spaces. It's just really wierd all around.

i have this problems mainly on the buttons M and Backspace on the swype keyboard with english layout. thats why i recognized the issue. i dont know if its anywhere else as well.
but sometimes it works pretty good, if i keep texting it just gets bad from one second to the next. but it will work if i press the screen "harder"...
any solution to fix it?

This isn't the same problem we're having in this thread. What you're experiencing is likely a busted digitizer. We're experiencing a clipped plane of detection all around the edges of the screen.
If you're positive that those specific spots on the screen never work then I would recommend you replace the phone.
I had a bit more time to play with this. i can doodle all day long in this so called dead spot but if i drag in from the bezel it doesn't register till 20 or so pixels in. Is that what others are seeing? It is on all sides

[APP]/[Guide] Flip Cover on AOSP rom's!

[How-to get partial flip-cover function on AOSP] This is no longer needed.
- Remember that this will require a magnet inside the case's lid.​
Hey guys!
I was fiddling around with our sensors tonight and I figured out the magnetometer is working in our device.
So I researched the Market and found an exciting application called Magnet Unlocker.
This application supports a lot of different ways to lock/unlock a device. Including with the use of a magnetic field.
Anyways, I did a lot of settings options and I cannot for the life of me get the application to both use Lock and Unlock, the unlock/lock processes get's jammed up in each other and starts to lock/unlock within seconds of eachother, so I basically use only unlock, since that's the most handy when I look at it. The device can still turn off by itself after a set time due to lacking user interaction.
With the settings I give you here, I have at least made the tablet turn on when the lid is flipped off the screen. The built-in dispay off setting is taking care of turning off the screen(in my case 1 minute after I close the lid)
So I present to you a small image guide on how to reach optimal settings.
I hope this is useful to you.

Nice find!
For those willing to spend a few minutes, I was able to get both cover Lock and Unlock working quite easily with Tasker and Secure Settings (Paid + Free). Secure Settings is needed since Tasker cannot turn on the screen in Android 2.3+.
To Lock:
Create a new Profile, State, Sensor, Magnetic Field. Press Scan and have a look at the value when the cover is nearly closed (you can peek under the cover). A value of 285+ works fine for me so far. So set From '285' and To 'Any'.
For the Exit Task, Display, System Lock.
To Unlock:
Same as before, just use the lower range: From '0' To '284' for me. (or you can use Invert)
For the Exit Task, Plugin, Secure Settings. Hit the pencil for Configuration and choose Wake Device. I then used Screen Dim and 5 seconds, but these are up to you. Press Save and you are done!
EDIT: I added a variable check to keep it from running constantly. I think it still needs a little work, things are a bit wonky, but get you get the idea. When it locks, set %CASE to CLOSED. In order to unlock, it must then read %CASE as CLOSED, before setting it to OPEN.

Really?? I have the IVSO case as well, and mine is much lower flipped around (~160 vs 330). That's weird. Does the smart cover work on stock?
You could try the method I describe with Tasker (no need for Secure Settings if not turning screen on) and set a small To and From window that just corresponds to your lid being shut. Maybe you need a delay to check twice to ensure it isn't accidentally triggered by the cover flapping while open.

These should not impact your battery life too much since the sensors are almost always on anyway as far as I can tell.
It seems that the values of the sensor vary greatly depending on the area; this means that in some places it works perfectly, but in others it won't respond at all. Could there be any way to input relative values of the magnetic sensor in Tasker as opposed to absolute values or some other way to mend this?

This was exactly why I only used one of the settings. The sensor is highly unstable and in certain occasions it decides to "double" the magnetic field. Sometimes I'm at like 400 when the lid is open and 800 when closed, should be only 4-500 when closed. It is based highly on situation. I'm sticking with the screen on function only. But thanks for the Tasker config as well. At least there's something now.

Do you leave the cover open just hanging off the side or do you flip it all the way around behind? Since the magnet and sensor are on the side where the fold is I have found I have to flip it all the way around behind the tablet to keep the screen off from being triggered. But this is how I like holding the tablet anyway.
Magnet Unlocker and Tasker don't work for me. Magnet unlocker reads my magnetic field as 900 with the cover open and 18 when closed, so when I close the cover the device unlocks. Tasker works sometimes, but after some time the magnetic field goes above 1000 so tasker is useless.
I tried this on Madhi-Rom and it didn't work for me either. The magnetic sensor isn't working correctly and didn't give values that made any sense. I went back to stock and checked with the app and the sensor reports correctly.

maybe I am not aware of what you are really talking about. Are you talking about using a cover with a magnet to turn on and off your tablet? When you lift the lid it comes on when you shut the lid it goes into standby mode? Maybe I misunderstood what really taking place here. But if that is the case then yes I am using a ivso cover that hibernate my tablet just fine.
