As per title.
Reason? Sometimes I would like to use different fingers with different orientation.
While I don't do this myself, you can achieve this by using more than one finger to train one of the "slots" on the phone. In other words, use one of your fingers to train up to about 50%, then switch to another finger. I just tried it out on my phone and it did recognize both fingers I used to train a given slot, but that was just a few trial unlocks I did in a more "controlled" way. I don't know what impact it'd have overall on accuracy in the various positions you often will hit the reader with in more "real world" use. Presumably it would to some extent mean it'd be less accurate or more picky, since there's less data about each "actual" finger in each finger "slot."
You can also do more than one orientation of a finger on the same storage slot. For example, Fingerprint one on my phone stores my right thumb horizontally, vertically, and diagonally, so I can hold my thumb in almost any orientation to unlock the phone. Slot # 2 has my right index finger in multiple orientations, etc.
You don't have to use one fingerprint storage location for horizontal thumb, another for vertical thumb, etc.

So I've had the Transformer update for about 20 hours now, which has given me time to play with it. The new circular cursor for the touchpad isn't a good design, but I can now see what they were trying to do, as they also use it to indicate touch and multitouch by filling the center of the circle with a dot for a single touch, and adding a second dot for multitouch. What they need to do is add a crosshair to indicate the exact click zone at the center of the circle.
An interesting side effect of the change, though, is that you can now very easily test crosstalk when using multitouch on the touchpad, and the result is NOT good on my B5O dock. I'd guess this is why many folks are reporting problems with multitouch zooming instead of scrolling or vice versa, etc.
To test: Touch the pad at right center with one finger. Move your other finger up and down the left-hand end of the touchpad without moving the other finger. Notice that not only does the left-hand white dot on the screen move, but the other dot also moves a LOT, when it should be staying still. I find it easiest to do this test in an app that doesn't support pinch zoom / scroll and has a dark background, so your eye isn't distracted by motion. For example, Moboplayer makes it easy to see.
Do the same thing again, but with one finger at top center of the pad, and the other at bottom center. If anything, the result seems even worse, to me. Even placing your fingers as far apart as possible at opposite corners of the pad, movement of one finger affects the other significantly. In some situations, it's actually possible to make the stationary finger's dot move exactly the same distance as the dot for the finger that actually moved.
I'm hoping that this is just a software issue that can be fixed in future firmware, but the logical side of me thinks this is more likely a hardware issue, and quite likely one that explains why they never offered pinch zoom until now, as they've found it tricky to try and work around and filter out the garbage data from the touchpad as much as possible.
I'd be interested to know whether the latest B7O docks show this problem too, or if it is improved at all.
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.

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!!

Tell me about it...
It's so irritating
are you sure you got it in left hand mode? i have mine set to my left hand and tried writing with my right. was off like you said (to the right). tried again with my left hand and it seemed fine.

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!
Do you find any difference when you change the screen orientation then back again?

None at all, unfortunately.
I find that no matter what I do with the pen it always seems to write half a cm above where I have contact on the screen

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.

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.
I have very good accuracy with the fingerprint scanner when it comes to flat finger swipes, however not very good luck when it comes to one handed swiping with my thumbs.
I have repeated the one handed thumb swipe setup numerous times with varying results, but less the great.
With that said, I decided to setup a couple of up and down swipes and have pretty much solved the one handed swipe problem in my case.
Hopefully this can be of some benefit to others.
:good:<--diagram of thumb used
I'm rooted on APG1 and I would estimate the fingerprint scanner success rate at about 30% (that's being nice, it's likely considerably lower). I've deleted and recreated my fingerprint profile multiple times and with both thumbs. Same pitiful results.
Any suggestions, tips, or hacks to making this work better? If it's worth noting, I'm using the Incipio Performance lvl3 case which does have a protective lip at the top and bottom of the phone.
Thanks.

"When setting up a fingerprint on the Galaxy S7, it's important to remember to grab at least two pictures of your thumb going across the sensor diagonally. If all you do is move your thumb from top to bottom or from left to right, it's easy to create gaps in that complete picture. Adding a couple of diagonal captures during setup decreases the chances of this happening, which in turn makes your failure rate significantly lower when unlocking the phone every day.
The oval shape of the Galaxy S7 home button is the real key here. As long as you remember during fingerprint setup that the fingerprint being stored is the result of 13 different presses on the sensor, each capturing a long strip of your thumb and not much else, it becomes a lot easier to deal with. You won't be pressing your finger onto the Galaxy S7's home button the same exact way every time you unlock it, so don't put it on there the same way every time when you're registering it in the first place."
My unlock success rate is 19/20, I have even set up 2 fingers from one hand and 2 from other hand on very different positions, so it does not matter how I hold my phone it unlock perfectly almost all of the time
