[Galaxy Note 8.0 (Tablet) General] bigmout:
I'm looking pretty closely. The test I use is to make a tiny dot in S-Note and see if I can start a new line directly on that dot. Works like a charm every time with the internal pen.

I was able to reproduce the cursor issue you mention in the address bar of the browser, but there is no offset when I actually touch the screen -- the cursor goes exactly where I want. What's more, there is no offset with the air view pointer anywhere else on the screen. That tells me the issue is specific to the text entry box and cursor.

I mean no disrespect because your work on this issue is outstanding. But I'm just not experiencing the general offset you and others describe. I'll certainly post here if I do, though.
[Galaxy Note 8.0 (Tablet) General] Elpidio:
what is your CSC code on your 4.2.2. so far, I've tried DBT and INU and the offset are there. if yours don't have it, you must be pretty lucky.:):)
[Galaxy Note 8.0 (Tablet) General] bigmout:
Where is the CSC code ?
[Galaxy Note 8.0 (Tablet) General] bibi_50:
To find your CSC code... go to the dial pad and type in...

*#1234#

You will then get a screen showing 4 lines of information, thus:-

PDA refers to the build version of the firmware

Phone refers to the baseband/modem version

CSC is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider.

for example, for me it's N5100OXACMH2

Build Info: The time and date of the build you are running.
[Galaxy Note 8.0 (Tablet) General] bigmout:
I have the wifi model (N5110). No dial pad. Is it listed somewhere in "About Device" under Settings?
[Galaxy Note 8.0 (Tablet) General] bibi_50:
Sorry.

If rooted, you can find CSC directory under SYSTEM .

Then , in one of XML files, you can find the CSC code
[Galaxy Note 8.0 (Tablet) General] bigmout:
D'oh. Not rooted. If it helps at all, I'm in the U.S. and just downloaded the update (N5110UEFMI1) over the air a couple of days ago.

Just had the MI1 update this morning in the UK and it's fixed the off set issue. Does anyone know of any other changes? The update was about 60MB
[Galaxy Note 8.0 (Tablet) General] civato:
I flashed full stock original MI1 rom and the offset is still there.

Cursor in text and the pointer is still not where it should be, right under the pen.

Samsung didn't change a thing in the framework and the kernel so in

my

opinion it is placebo effect that users with the MI1 have.

I would like to see a picture taken with the so called

no

offset, pointer/cursor right under the s-pen.

The offset with pointer is like the pointer is at 3to5 o'clock where your pen is pointing.

The cursor is 3-4mm of to the left.

So post a picture where it proves on your tablet it is correct. Call me a pain in the a$$ but I don't believe that it just disappeared without any changes made to the X /Y axis in framework and kernel driver.
[Galaxy Note 8.0 (Tablet) General] LomDiV:
I attachment photo of my Note 8. it is definitely better than MH2.
[Galaxy Note 8.0 (Tablet) General] intelliriffer:
No Placebo effect here, I was one the first to revert back to 4.1.2 due to offset issues and the current update (MI2) 4.2.2 in india is as good as 4.1.2 (original) if not better.

I don't know much about text etc, but I use sketchbook pro and it is spot on for me.

Drawing a cross and then drawing lines passing through intersection are perfect (at very thin pen settings)./

now that blue dot that samsung shows might display some offset but i have it disabled anyways and where I touch I get a dot, unlike some of the previous updates.

Attached are two super macro images. (sorry handheld,and bit noisy but should do) the one with blue dot has some distance from screen, and the other one is just touching the screen.

3-4 mm is a quite a lot of offset even 1-1.5 mm is a lot.
[Galaxy Note 8.0 (Tablet) General] civato:
Ok I got it thanks, I also took a look at samsung source releases and guess what, they released a new kernel source with a driver fix for the s-pen. Update2 .

EDIT:

Compiled new source and a little improvement but still a offset is noticeable in S-Note when writing text.

My fix in the source solves that so samsung needs to redo it's homework and maybe take a look at my source.

It is true in apps like sketchbook there is improvment but just give my kernel a try and you will see the difference on how it should be.

S-note is way off in the original source.

My conclusion, s-pen is better but not fixed. Maybe 90% of the users will be happy with the original samsung settings but I'm not as it needs to be spot on.
[Galaxy Note 8.0 (Tablet) General] gabripranzo:
Hi Civato, if I remember well your fix consists not only of your kernel (which I installed and enjoyed a lot) but also in a modded framework for the text cursor. I have tried to look for it to install separately from your rom (I was sure it was available, or maybe I am wrong?) but wasn't able to find it. Can you help me?

Thanks!

Updated OTA to N5100XXCMI1 with the following results
[Galaxy Note 8.0 (Tablet) General] gurudev32:
For Update

S-Pen accuracy
[Galaxy Note 8.0 (Tablet) General] intelliriffer:
This is the Erratic offset I had prior to the MI2 release, and it was very bothersome.

If on MI1 you guys and civato are getting this amount of offset then Yes, It's Bad.

Wondering if MI2 has some different tweaks applied as opposed to MI1

Thanks,I would have tried your kernel much earlier if i was rooted, however I am all stock, until I have the warranty (have had entire display and motherboard replaced, half of it was my expense). I really want to do me some tweaks to audio etc but holding myself.

No problems on mine in S-note either.

Here is simple test in s-note for offset for anyone interested.

1:eek:n a Memo Note (Free hand) select the first pen and set the pointer size to the minimum width.

2: tap once to put in a point.

3. now draw a line starting from that point like you would with any normal pen (all directions).

if you are consistently able to hit that point and start line from there. you don't have offset issues (or at least within acceptable tolerance). however if where you hit and where the line starts has even light gap then you are suffering from offset.

Another way to check ofsset is in s-note switch to the eraser and set it's width very small bot not the smallest and now when you bring the tip close to screen you should really see what your hit point is.

I do have a tiny bit offset with eraser but not enough for any practical impact.

See attached taken from s-note at thinnest of the pen settings the offset if any is barely noticeable).
[Galaxy Note 8.0 (Tablet) General] turt:
Just noticed new N5120XXCMI1 from Portugal (TPH).

Does anyone know if it contains the new kernel with (at least partial) fix for s-pen inaccuracy?

Thanks
[Galaxy Note 8.0 (Tablet) General] civato:
Well all that pictures a side and opinions, the offset is still there and I could care , less if it is small or barely noticable.

The only thing that get it 100% accurate is my kernel and framework.

If you want accurate drawing it needs to be spot on even a offset of 0.5 mm is to much.
[Galaxy Note 8.0 (Tablet) General] intelliriffer:
Sorry, but it was you who did ask for pictures and were provided for (I shot them with a dcr 250 super macro/closeup lens).

so will all due respect (as i have high regards for what you do), believe what you have to, no one is questioning the accuracy of your kernel or what have you else.

I just said things as they were and as i found them in this update. Maybe MI2 has better tweaks that MI1 maybe not, Maybe I just Happen to Have Very Special unit, or perhaps all devices in my region.:silly:

as I posted above in regards to what image another user has posted with MI1 update and if it is what you are having then Yes, it's a really bad (that is the amount i had prior to MI2 update and was unacceptable).

however for all practical purposes

I do stand by my findings

with the current update, for someone who brought this tablet primarily for reading/graphics artwork and has been using other wacom tablets graphaire / intuos with photoshop/illustrator for more than a decade .

Please don't feel offended from choice of my words, as not my intention , however i'd rather, it's samsung who fix this issue with their stock (on devices where issue still exists because they had it right earlier too). Your kernel provides a viable alternative for those who need it right away,but does not make it the only way. You yourself acknowledged some improvements for Your Device (if not spot on) so samsung already did some improvements, though apparently to a somewhat varying degree as evident from this discussion. There has been no quantifying measure of the magnitude of the offset either, but only that it exists, By how much it itself differs from model to model./ release to release is I believe something samsung will be more equipped to ascertain.

I as well perhaps some other users might be skeptical to go through rooting/kernel swapping procedures that may void warranty or anything, call me naive or paranoid but seeing the ever degraded quality of the stuff that's coming out of manufacturing. I'd rather be stock as long as i can if it does/provides all that I need from it.

The s-pen and it's accuracy is something that is native and needs to be fixed stock as it's not some limited/missing functionality but rather a critical primary parameter/factor of the product line.

Also considering the New Note 3 and it's Knox eFuse, Kernel swapping is not even an option without permanent rigging for certain, if a similar offset issue ever pops up in there.

The purpose this thread (to my knowledge) is serving is the acknowledgement/findings from the users all across, of the plain simple facts that in regards, to s-pen and on going samsung updates (and 4.2.2) and what has improved?, how much it has improved? and has it improved all across the realm? (which is evident is necessarily not so). :)

On another note and off topic. if your kernel has plug and play support for game controllers like xbox 360 on note 8 without needing third party apps /settings or configuration requited each time that'd could be very tempting.
[Galaxy Note 8.0 (Tablet) General] civato:
Dont get me wrong, I appreciate your pictures but again there is still a little offset so in my opinion samsung needs to redo its homework

You can clearly see the offset in the pictures, if it is not a big deal for you ok, but for me it is as this is a tablet you buy for the spen. If not you got other tablets then the note series. Meaning it gotta draw the line where I put the pen..
[Galaxy Note 8.0 (Tablet) General] lcampori:
Adding my 2 cents.

Just updated to Uk mi1, no s-pen offset, as far as I can see. While I really do appr appreciate civato's work, I completely agree with intelliriffer, Samsung has done its homework.

Inviato dal mio GT-N5110 con Tapatalk
[Galaxy Note 8.0 (Tablet) General] intelliriffer:
Yes, Samsung definitely need to do it's homework and if there is a way to even petition them to look at your modifications to the kernel source then count me in.

Like I said , for me it is drawing the line where i put the pen (even when zoomed out to 50% or zoomed in to 200%). If you are into drawing , feel is everything. not the blue blob pointer that is there. If you can't start or continue on a line segment/curve like you do on traditional paper with a fluid motion then something is definitely wrong.

however I am certain that there is some issue with different releases by samsung because like the other user posted with MI1 Update, his offset in the image is unacceptable.

See the firmware build dates here.

N5100DDCMI2 (INDIA)

MI2 (rev 2) PDA Build is from 19th Sep

Where as N5100XXCMI1 (Open Europe/ DBT Germany) (Rev 1) PDA build is from 16 September.

So Rev 2 certainly has some changes compared to it's previous build (which never got released perhaps,QA/QC got to it), which may or may not be related to this issue.

I haven't jumped into android dev, but will see if i can lay my hands on the source codes (if available) and do some diff analysis.

Don't know for sure but they might have put in some fixes in their proprietary closed code elsewhere, unlikely but possible.

[Galaxy Note 8.0 (Tablet) General] FaeMinx:
I'm not going to even consider updating from 4.1.2 until 4.3

My tab is set up nicely and I certainly don't want any accuracy issues. I can't see what 4.2.2 brings to the table that I would find useful and would be worth the risk.
[Galaxy Note 8.0 (Tablet) General] whitedavidp:
Hello I am the author of the Reset Spen app in the Play Store. I heard today from a user of a Note 8 who just moved to 4.2.2 and now he reports my app is no longer working. It always shows the following error: "Pen configuration not found". In trying to discover what has changed I found this thread.

Can anyone with this device tell me if they too are getting this behavior from my app? I don't have a Note 8 so cannot test it myself. Thanks!
[Galaxy Note 8.0 (Tablet) General] gabripranzo:
I have just installed your app, but when I try to open it there's a message saying "pen configuration not found".

I have android 4.2.2

Sent from Galaxy Note 8.0 GT–N5100
[Galaxy Note 8.0 (Tablet) General] Minepow2:
Well, I think I already know the issue; the epen_hand config file does not exist in this version of the OS. I am curious if copying a epen_hand file from 4.1.2 or from another Note device will fiix the issue... could you upload yours so I can do some testing?
[Galaxy Note 8.0 (Tablet) General] whitedavidp:
Thanks for the report. This is consistent with what I was told.

---------- Post added at 12:13 PM ---------- Previous post was at 11:52 AM ----------

I believe that the epen_hand file is a special device driver file for i/o and cannot simply be copied. I think the system has to create it.

The absence of this file would be consistent with the error being displayed by my app. However, this was the second thing I asked the user to check when he reported the error to me yesterday. I had him use a rooted file explorer and actually look for the file. Surprisingly, he found it where it should be located at /sys/class/sec/sec_epen/epen_hand. He sent a screen capture of the file explorer showing the file and the expected permissions on the file. Do others find it as well?

If so, I am wondering if something has changed the permissions on the path to that file? On my Note I (GT-N7000) using ls -l, I see the following:

drwxr-xr-x /sys

drwxr-xr-x /sys/class

drwxr-xr-x /sys/class/sec

lrwxrwxrwx /sys/class/sec/sec_epan -> /sys/devices/virtual/sec/sec_epen (which has drwxr-xr-x)

--w--w---- /sys/class/sec/sec_epen/epen_hand

So this permits even non-root users to "see" that the file exists. My app tests it simply using:

static boolean isSpenDevicePresent()

{

File f = new File("/sys/class/sec/sec_epen/epen_hand");

return f.exists();

}

If the permission changed somewhere along the line, this might prevent non-root users from "seeing" that the file exists. And this would cause the message that is reported to be shown.

Can anyone confirm this hypothesis and let me know the permissions on the path to this file? If true, I need to re-organize my code to perform this test under su.

Thanks.

Reset Spen (updated)

Acting on my theory of what has changed in Android 4.2.2 on the Note 8, I have updated my Reset Spen app to version 1.2 trying to work-around the issue. I'd appreciate knowing if this now gets beyond "pen configuration not found". If the app completes its work, you should see a "success" message. I am not sure if this will improve your results on this new version of Android but I would like to hear. Thanks
[Galaxy Note 8.0 (Tablet) General] Minepow2:
Okay, after testing the application, it seems to work as it should... mostly. When the app is used, Touch Wiz seems to freeze. To unfreeze it, I just hold the menu button down until the app switcher appears, then exit the app switcher. This seems to unfreeze Touch Wiz. When this does not work, I just reboot the Note 8. During the freezing, the cursor still appears, but I can only interact with the Notification bar. Otherwise, all seems good! :good:

EDIT: I may want to mention that I do not get a literal message saying "Success" that I can see.
[Galaxy Note 8.0 (Tablet) General] whitedavidp:
Hah! Thanks. I will revert it back. Sorry.

---------- Post added at 09:15 PM ---------- Previous post was at 08:46 PM ----------

Sorry to ask but:

(a) Is your device rooted?

(b) If (a) is true, were you prompted for (and gave access to) su/root access to this app?

(c) If (a) and (b) are true, can you tell me which SU program you are using and its version (SuperSu 1.75, etc)?

Thanks
[Galaxy Note 8.0 (Tablet) General] Minepow2:
Oh, I am fine with answering your questions:

(a) Yes, my device is rooted. I used CF-Auto-Root.

(b)I was prompted for and gave su access for the app.

(c) I am using SuperSU. My version was 1.60 while I was testing Reset Spen. After updating SuperSU to 1.75, I have the same result.

If there is anything you need, I am willing to give a hand.
[Galaxy Note 8.0 (Tablet) General] whitedavidp:
Hi and thanks for the help. All I know about auto-root is what I see here. It seems this is designed to be a "bare-bones" root and that's great. One thing that my my new code did (version on Play is reverted now) is issue the linux commands (as root):

"ls /sys/class/sec/sec_epen/epen_hand"

"echo $?"

"exit"

A hang might occur if one/more of these commands were not found on your device. It is my understanding that these can come from either the toolbox or busybox executables. Perhaps there is an issue there? If you have a command terminal app installed, perhaps you can use to first issue the "su" command and then the 3 above and let me know what you see.

Thanks.
[Galaxy Note 8.0 (Tablet) General] KukurikU:
The file is there on Note3 and mysteriously disappeared from Note 8.

Your app still works on Note 3 (getting the "success" announcement). On Note 8 still getting a warning for the missing file.

BTW, after jumping to 4.2.2 on my Note 8 the S-Pen alignment is

perfect

! I wrote today 7 pages and once again it was a pleasure using Note 8.
[Galaxy Note 8.0 (Tablet) General] whitedavidp:
Thanks for the update. Can you tell me the Model of your Note 8? And the build number of your 4.2.2? I presume you are using the stock kernel. Correct?

Cheers
[Galaxy Note 8.0 (Tablet) General] whitedavidp:
I just want to be clear here for anyone who is following this. As of the official Android 4.2.2 release, Samsung has removed an element from the Note 8 kernel that my app (Reset Spen) requires to do its thing. This has always been the case with the 10" tablets and now the 8 has followed suit. I have no idea why Samsung has chosen to do this. But in the absence of the required kernel support, I can only hope that Samsung has implemented some internal method (as others have suggested) to keep the SPen's alignment in shape.

My version 1.2 (mentioned above) was removed because it did not work and caused hangs on some devices. It was rolled-back.

Perhaps there are custom kernels for the Note 8 and 10 that supply the needed kernel support. Look for the presence of a file called /sys/class/sec/sec_epen/epen_hand and you have a good chance. Another clue is the presence of an SPen setting among the system settings for dominant hand (left/right). But the real issue is the presence of the file.

Cheers!

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tidu12:
Hey, I am now very much fed up with this Sprint Samsung Galaxy S4 Phone.

A few days ago I was trying to unlock my phone using simlock code *#0011#. That did NOT work! I tried other alternative methods to get even the sim card connect like connect to network. I used DFS CDMA tool to change my IMEI number but still nothing.

Then I found out about the nv_data.bin file. I rooted my phone, copied the "efs" folder using root browser not with command or anything I just copied it into my phone then to my computer. I then used EFS Pro tool //(I wasn't able to backup the efs folder before with this software)// to format the efs folder, then I copied the efs folder from the phone's other location and change the keystr to ON and factorymode to ON to get back my power menu and take out the yellow bar from comming. After that I checked that my baseband is saying unknown and IMEI is unknown. When I type *#06# to get the IMEI, it says "MEID" as title of the box and nothing else not even zeros. Also I do have only one file called maps_code.dat file in the /efs/imei folder. i mentioned this because I've read others' posts that they have maps_code.dat, keystr, and bt.txt files.

So Can anyone here PLEASE HELP ME!!! WITH THIS PROBLEM!!!

I have tried lots of different methods, none worked for me to restore the IMEI number I even tried to look into the nv_dat.bin fole using hex editor, but it says "ffff" and on the other side dots thats it. i looked at others, they had numbers and letters into them. However mine doesnt have any thing except "fff..." i can send all the pics you need to see.

THANKS!!!
