S pen is not accurate i mean it dosent start from the point of touch is everovody facing this problem or is it device specific

i experience this. It's annoying when trying to be serious with drawing. Accuracy just isn't there. Forget going over places you've already drawn on.
I updated to 2.3.6 and now is perfect
Just did some quick test, and found why some may notice this inaccuracy and others dont. Cliffs: accuracy is factored by the angle you hold the pen, combined with the angle the phone things you're going to be writing or drawing on it.
Often times when writing, things look okay. Place the phone flat on a table, and attack a drawing at various angles and things go wacky.
I believe the setting where it asks you if you're right and left-handed, is just a setting for a pre-programmed x,y offset. If you're in portrait mode, and you hold the pen at an angle they think is proper (somewhere between 0 and 40 degrees on X and 0 to -45 for Y for right-handers) then things come out fairly right. This setting really messes things up when you want to draw from different angles without adjusting the offset. You can only change this offset (which it does automatically) when orienting the phone between landscape and portrait. But what happens if you want to draw at a different angle but not change the way the phone is oriented? Things go wacky.
If the phone is flat on a desk, no matter how you rotate the phone on its Z axis, the offset stays unchanged obviously unbeknownst to the phone. It is still under the assumption that your next stroke will be from the orientation it was last in before you placed it flat. This is when things appear inaccurate. You rotate the phone to landscape, but the phone (and pen offset) is still in portrait mode. Your next stroke is way off.
So to get accurate strokes, hold the pen the way they think you should be holding it, and also make sure you're doing so on a screen that is properly oriented.
Due to the way the tech of this digitizer works, it seems we're stuck with this "feature". If we can apply this offset in real-time and not just at 0 and +/-90 degrees, but to apply it in real time throughout the whole range using the gyro then we can make it slightly better when the phone is in-hand and writing at different rotation angles. This solution won't work obviously, when the phone is flat like on a table though.
Until then, solution is to mindfully draw/write at the "correct" angle RELATIVE to the screen orientation.

These are very good observations - good work.
So in short,
1) Make sure 'handedness' is set correctly in settings (left/right handed)
2) 'write' at a ~30-45 degree angle or so.
3) You can't rotate the phone when it's on a desk. You can, however, pick up the phone, rotate it to an arbitrary angle, and then set the phone down at that angle. (easier for you to just try).

But obviously there is bit of lag too when you touch the pen on the screen. It is difficult to draw pricesly on the note this certainly put me off.

Ok everybody, grab your phone and TURN IT UPSIDE DOWN. notice how easy it is to use the joystick/thumb navigation button. in fact, this works nicely for any bar-style phone or device. the screen remains visible next to your palm and thumb. this is such an obvious idea once you think of it. I once wanted to patent this. but somebody already had a similar idea. please, if you use this idea, try to give me credit. call it the Bessler upside down phone or something. anyway, can someone make a program that will flip my screen upside down? wm5 only has two landscapes and a portrait. Thanks
wow...
here there's a program that flips the screen upside down when you click on it multiple times. only problem is the buttons don't switch direction.
http://www.geocities.co.jp/SiliconValley-Cupertino/2039/
And here's one that rotates 180 degrees in one go:
http://www.pocketgear.com/software_detail.asp?id=15332
There's three readily identifyable problems with holding the device up side down, though.
1. I'm not sure how ergonomic it really is. I've attached pictures of me holding the device up side down, and upright. You'll notice that in the first up side down picture, my thumb is relaxed, but as a result obscures the screen. To make it not obscure the screen, I actually have to bend my thumb which, other than eventually inducing pain, leaves you with less control as you're navigating with the top of the side of your thumb. Maybe I'm holding it entirely wrong though
2. The buttons issue. 'nuff said. This probably a programmatical error, though - must me some manner of telling the operating system that you rotated the screen, and that the buttons should follow suit.
3. ClearType. ClearType assumes the ordering of your LCD is RGB. If you rotate the screen, the ordering is BGR - but ClearType still assumes RGB. The result is that your screen becomes very difficult to read when using ClearType. The solution here is to disable ClearType, but who would want to do that? %) Images of what this looks like are attached as well. Note that I actually had to cheat the images, because if you rotate the 'up side down' wrong order screenshot back to normal, the ordering becomes RGB again and it looks fine. You can try it for yourself to make sure my screenshot isn't bogus, though
i couldnt find a thread that explains exactly what it was... is it hardware or software...
hardware. I think its a type of accelerometer.
my wife is also interested in this.
so my phone wouldnt have it then.. doesnt the camera have some kinda sensor like it in it?
your wife needs to get a diamond or touch pro...

As far as I know it IS an accelerometer. Same thing I would say. Don't have much knowledge, but it's basically the same technology the iPhone uses. It can detect how you're holding your phone. Yes, you could use your front camera on your phone as a accelerometer and it's been asked before, but no one attempted to do so since it would consume too much battery.

yea i wasn't really sure if it differed from an accelerometer. I used google and wikipedia and i couldn't find anything on G-sensor, and I didn't find G-sensor under the accelerometer wikipedia entry.
but yea, basically the technology that iPhone uses.
someone should do it...
its an accelerometer which is hardware to do what the iphone does where when u turn it to its side its screen also changes to the sideways orientation.
It detects which way the phone is facing and can detect acceleration in 3 axis.

Ah, there is the more technical answer. It can detect movement. Basically you use the 3 axis which detects movement in all directions. You tilt left and right and you tilt up and down. I knew that just didn't know the technical meaning lol.
In most cases the G-Sensor is simply a small metal ball laying in a tub with several contacts. When you turn or move your phone, the ball moves also, connecting some of these contacts to anothers. So the phone can figure out how you hold it (portrait or landscape, upside down etc.) and can switch the screen or perform different actions. Its called G-Sensor because the ball is driven by G-Force.
What is G-Sensor ?
A G sensor is usually an accelerometer. It measures the forces that act on it during changes in velocity. The wiki article below has more details.

False. It's a three (and probably sometimes two) axis MEMS accelerometer - there are a few companies making those, but probably the most popular ones are analog devices' ADXL series. Similar device sits in wiimote (just as a secondary motion detection system, the more accurate one is camera+sensor bar).
Because these chips became really cheap recently, and are way more accurate, reliable, and robust than any mechanical sensors (in the same price ans size range), they're being shoved in every possible device You can find them in digital cameras (used to recognize if the photo is portrait or landscape and tag it accordingly), in hard drives (to detect mechanical shocks and protect the hdd by parking its head), in laptops (usually same as above plus to detect when the computer is falling down or other dangerous situations and protect the hard drives), in cell phones (you probably know this one's uses), in toys, portable media players, and lots of other stuff.

A more precise answer is that it detects acceleration in three axes, and from these values phone's orientation can be calculated.
[MORE DETAILED EXPLANATION]
It's rather simple - when the phone is normally handled (it's not free falling and it's not being waved around), the dominant acceleration detected by the accelerometer is the gravitational acceleration (-9.81m/s^2 in vertical axis). So, if most of the time acceleration detected along the vertical axis of the phone is bigger than one detected along horizontal axis, the phone is being held in landscape position. If the situation is reversed, it's held in portrait orientation. If the acceleration is largest in the third axis (tangent to the screen), it means that the phone is being held nearly horizontally or it's lying on some surface - better not change screen orientation then
But as i said - it's only true when the dominant acceleration is the gravitational one - the sensor can't tell it from other sources of acceleration like waving the phone around. If you run one of the g-sensor games or demos and try quickly moving the phone around the desk (keeping it horizontal at all times), you'll see that the game will interpret this movement as tilting the phone.

The theory of operation is actually pre-high school level stuff - basic physics (you know, Newton's laws, and theory of gravity)
And the details - caught some of these at the engineering university, some from accelerometer datasheets. I had to interface one of them to a programmable microcontroller a while ago so i needed to do some research on my own
I just got a TP2 and is a bit confused as to the working of the G-Sensor. I have calibrate it (and it is switched on), but nothing happens when I turn the phone sideways - ie turning to landscape mode. Am I missing something or need to activate it somewhere else?
Thanks

Hello, try to search on your programs, you will have "G-Config", it allows you to define which applications rotate.
Thanks very much. I searched but couldn't find any G-Config anyware in All programs. Only reference is the G-Sensor in All settings\System.
EDIT: Google reveiled G-Config to be a self written app. (just downloaded) So it's not a HTC app included in the ROM?
Am I the only one that seems to be having a major issue with this? It comes up more with the added on screen keyboard in 1.5, it seems.
The corners of the G1 screen do not respond to touch at all, and I find myself always having trouble hitting the keys on the corners of the virtual keyboard. Applications that require you to touch any corner of the screen with precision (ie tic-tac-toe) are annoying as well because it's difficult to get it to work.
Is there any fix in sight or is it a hardware limitation?
definitely a hardware limitation.
hardware limitation means: normal hardware limitation or limited due failure????
I only experience this problem with the right edge of my phone. The top, left, and bottom don't have any problems.
Touch also seems to be less sensitive when the phone is rested flat.
My phone has the sensitivity problem on the edges too (mostly on the right and top sides).
For example, it's almost impossible to drag an icon to the left screen, because it doesn't seem to reach the threshold area.
The protective screen (boxwave anti-glare) made the problem even worse, but since it's much more comfortable than the glass, I won't be taking it off.
The easiest way to test all this is to use the whiteboard application.
So, I ask the developers: Please don't place the buttons on the edges of the screen!
The worst apps in this regard I've seen so far were the Video player (don't remember its exact name, its seek slider was unusable), and the sudoku with the number chooser in the bottom. OpenHome's app slider has the same problem.
sometimes my phones touchscreen becomes unresponsive when its flat on its back on a table for example. I unlock the screen with the trackpad or power button so that the screen comes on. Then when i try to slide the lockscreen it doesnt do anything. When i begin sliding the bar from the total edge of the screen it sometimes works.
Usually i just have to pick up the phone to get the touchscreen working again. actually, when i even lift up the phone the slightest bit, it works again.
Weird right?
anyone else experiences this issue ?
I assumed it was designed to work like this. Makes me move my phone rather than just slide to snooze the alarm then go back to sleep.
Same here. I think it has to do with the capacative toucscreen.

you're saying you move your phone to snooze the alarm? didnt know it could do that, gonna try that out tomorrow morning
forgot to mention the issue is not ROM specific. I have witnessed it on virtuous, CM, MIUI, stock
Ive had this problem as well. Slightly annoying!
I don't think its a design issue..
you don't have to lift your phone to get the screen to respond.
notice that it is enough just to touch the body of the phone to make the screen responsive again..
for me its very annoying, especially not being able to snooze the alarm in the morning
Let me point out that this happens with my G1 also so its not just the G2.
Yeah, there are a few discussions about this on the forums already. It's most likely a capacitance issue. When your phone is just sitting on a table and you touch the display, you may not create enough capacitance with the touchscreen for it to register as a touch (as opposed to resistive touchscreens which needed only physical contact but were less accurate as a result). Touching the body of the phone basically creates a common ground or voltage reference point for the phone, allowing your finger to create the needed amount of capacitance (in technical terms, no longer a floating ground). Whenever I touch the screen while the phone is lying on a table, I just always make sure to rest either my thumb or ring finger on one of the edges.
A lot of factors will also come into play---whether or not your phone is in a case, type of material the phone is resting on, the level of humidity in the air, even potentially the type of shoes you are wearing. This is why sometimes it works and sometimes it doesn't.

yes! I just figured this out myself. merely touching the body of the phone makes the screen respond to my fingers.
well in that case its not really a big problem. from now on i just touch teh body with my middle finger while sliding with my index finger =D

This seems to be temperature related (and it doesn't happen on a mytouch 3g)
I live in Minnesota and I deliver pizza. When I would need to call a customer to get into an apartment building, I would set the phone on top of the pizza bag and dial with one hand.
When I first got my G2 (early november) I had no problems doing this, then one day it wouldn't respond at all to touch. I still had my old mytouch 3g with me because the old number wasn't ported yet, and I was able to use that to make the call. It wasn't until later that I realized that the problem was caused by the cold and that I needed to touch the metal part to make it work, so I thought that the touchscreen on my 2 week old G2 had just died.
At room temperature the touch screen always works (I can silence the alarm while it's sitting on the table), but temperatures below 50F cause problems
I started noticing this as well. Sometimes I'll hit the power button to turn my phone on from idle-state and then I'll drag the unlock button with to no avail! But then again, I do use my thumb to do it so maybe the capacitance by using the thumb isn't good enough to unlock it.
I use my phone at work a lot so in order to text while being discreet, I usually have the phone in my right hand and text / unlock the phone using my thumb. I doubt it is a defect but it had me worried too. Guess I'm not the only one experiencing this. (Although I must say, dragging my thumb to swype and using the side of my thumb probably is the reason why it sometimes doesn't work)
Back when I had my g1 it did the same thing and experience this on my g2....if its laying down its like it thinks its just on in your pocket so the touch seems limited

Not weird. TOTALLY normal and expected.
It is because it has a CAPACITIVE TOUCHSCREEN.
This means that when you touch the screen, your finger is actually COMPLETING AN ELECTRIC CIRCUIT.
When the phone is lying on a table and you touch it, you are NOT completing the circuit since you are NOT touching the phone's body.
When the sensor is on, there is an electrical difference between the surface of the screen and the body of the phone. When you touch BOTH, you alter the electric field in that localized area of the screen. The sensor detects the change in voltage and determines the location of the contact.

So how do I adjust the sensitivity? As I understand it I could increase the voltage to the screen making it easier to complete the circuit...such as through thin gloves.....

No touch a finger on the phone body and do it again, itll work.

Someone was just pointing out that if this was "precisely" true as you put it, then the screen should never be responsive if you aren't touching the phone's body (since the circuit is, based on your reasoning, still broken). This isn't the case though since it does work sometimes. How could your statement be precisely true if it's known to be false sometimes (hence the "mostly true" comment)?
And it's actually not true. You are not completing an electric circuit. No current flows from your finger into the screen and no components within the phone are electrically coupled because of your touch. As you stated, you are altering the electric field when you touch the screen. This results in a change in capacitance in that area. Note, this change occurs even when you are not touching the phone's body, just to a different degree. Touching the phone will typically increase the amount of capacitance as opposed to when you are not though (since you are basically "grounding" yourself to the phone). The more capacitance there is, the easier it is to measure. If there is too little capacitance, the touchscreen's microcontroller will not register the change at all. Even if it does register the change, there will be additional filtering that occurs to that raw data either in the microcontroller itself or in software (or both).
This is why the screen works sometimes when you touch it without touching the rest of the phone. You are still causing a change in capacitance. The amount of change depends on numerous factors (this is what I stated in an earlier post). These factors effect how grounded both you and the phone are relative to earth ground (in the electrical sense, not geographical). Typically speaking though, if you are relatively close to earth ground, then you will be able to use the screen without touching the body of the phone. For example, someone stated earlier that the screen doesn't work when it's cold. Cold weather results in lower humidity/drier air and you being less grounded (basically why people see an increase in static electricity as well). Chances are that the touchscreen would work again without the touching the phone's body if you had physically been touching a large piece of metal with your other hand (to help ground you).
So in response to the other question posed, yes, technically by raising the voltage level to the touchscreen, it may result in a more sensitive screen since there will be a larger increase in capacitance when you touch it. It may also reduce the life of the touchscreen though, if not damage it completely, so not a good idea. It would be better to figure out the filtering mechanism if possible and adjust that in software. Not sure if any devs have looked into it (though my guess is that if it was simple, it would have been done already).
I am so happy I found this thread..
Lately I thought my touchscreen was broken because I was unable to snooze my alarm in the morning (just as some of you seem to have been trying to do).
I think it's temperature related as suggested by the person who mentioned pizza delivery.. and I think this because it only happens on mornings where I've left the bedroom window open and it's very cool. My phone is often on a cold wooden surface. however even picking up the phone doesn't seem to help (I'll have to pay more attention next time) but after a few moments of struggling it eventually works (probably warms up in my hand and gets a better circuit).
I can also vouch that the screen works great with just a single finger on a flat surface, provided it's room temperature. I don't need to touch the body at all, and I do this a lot without issues (aside from cold mornings waking up to my alarm).
As a left-hander, the S-Pen SUCKS.
I've set the phone to left-handed, but that isn't the issue.
The phone expects the user to hold the pen at an angle away from the user, and that's where the screen registers.
However, many left handers hold their pens at an angle TOWARDS themselves, and the S-Pen is off by nearly HALF A CM!!

I have it set to left handed.
When changing the settings to right-handed and using my right hand (I'm a little ambidextrous) it works fine. Nice and accurate. Mostly because with my right hand I hold the pen at a conventional angle.
However, many lefties don't hold their pens conventionally (habits picked up by the necessity of avoiding ring bindings, minimising smudging, etc). Look at how President Obama holds his pen:
http://www.post-gazette.com/pg/images/200901/20090126ho_lefthandedobama_330.jpg
See how the nib of the pen is angled TOWARDS him? The Note thinks it's angled away and puts down a line in totally the wrong place.
Even with my slightly less unconventional left-handed pen hold, it's WAY out (no matter whether the unit is set to left or right hand use, though left is slightly less awful).
How hard can it be for Samsung to provide a calibration app?
Right now, the Note is a phone unsuitable for a President!

SPen uses autocalibration feature, which unfortunately goes off after some time. Which is a bug by itself but not the point..
Everyone complaining about pen being way off try this:
set it to whatever your hand preference. Please phone on flat surface like a table and reboot phone. Do not shake or touch it too much. Open SNote and try to draw around grid lines, you will see that pen works perfectly with tip being exactly as expected.
However more you use pen more it will deviate off until reboot is needed. It happens especially fast if you are using it walking, upside down etc.

However more you use pen more it will deviate off until reboot is needed. It happens especially fast if you are using it walking, upside down etc.

Interesting (though it didn't help in my case)
But it the calibration goes off after time, then there is even more reason to add a calibration facility.
I reckon that only happens when you're using landscape orientation and then you turn off autorotation without first returning to portrait orientation. Try turning autorotation on, setting it to portrait and then turn it off. That should fix it.

Thanks, but it really is nothing to do with orientation in my case.
It's ALL about the angle at which you hold the S-pen.
It expects the nib to be angled away from you, whereas I hold a pen with the nib angled towards me.
