Hi,
I've found on my Note 10.1 that the accuracy of the S-Pen gets worse near the edges of the display. At the very edges it's off by about 1 mm or slightly more. I can't say it's really caused any problems but I'm wondering if this is normal and if there's any method to better calibrate it?
I've been having the same issue, or at least I noticed it recently...
Does anyone know anything about this problem?
This has been bothering me a lot lately, especially since i use my Note for note taking. Bump in case someone knows the solution.

Here's the response from Samsung support:
Thank you for contacting Samsung Customer Care.
We understand that while using the S pen near edges it looses accuracy.
We are sorry to hear that.
Please try replacing the S pen tip to isolate and fix the issue.
It is not possible to calibrate the digitizer.
Thank you for contacting Samsung.
Kind regards,
Steve

I''''ve found the S-Pen (as viewed by enabling the hovering pointer) loses accuracy the closer to the edge of the screen the pen is used. At the edges it is off by at least 1 mm. About 1 cm in from the edges the accuracy is good.
Is this a defect in my unit or are they all like this? is there any way to recalibrate the digitizer to improve accuracy?

I tried changing the tip with both types of tips supplied with the tablet and as expected it had no effect. Note, also, how utterly useless Samsung email support is. The only way to reply is through a link which sends you to a contact form to submit a new email from scratch. There's no incident number or any way to establish continuity.
In any case, I happened to be at a Microsoft store yesterday and played a bit with Samsung's ACTIV (sp?) pro Windows 8 tablet which has the same s-pen as the Note 10.1. What I noticed immediately is it behaves exactly like my tablet: the digitizer loses accuracy both when tilting the pen and especially when the pen is near the edges of the display. The amount of inaccuracy is just about the same too, about 1 mm near the edge.
So I suspect this may be a limitation of the technology or at least the technology as it's being used by Samsung (I'm surprised Wacom's stuff is not more accurate). I'd be particularly interested if anyone is NOT seeing this.
It also seems silly that the display cannot be recalibrated or the driver does not support remapping. This seems like something that should be pretty easy to implement.
On the positive side, I can't say that I've experienced any real accuracy problems when in actual use. Probably I don't tend to write so close to the edge where it might be an issue. It's more an annoyance that the cursor doesn't quite match the tip. It's actually less annoying than having my hand trigger s-note's zoom or the notification drawer every time I try to write something.
Too bad, samsung support is horrible. For me this problem is pretty annoying since I tend to write until the VERY edge (just like I do in real paper), so I guess I'll have to change my habits lol.
P.S: It's good to know that is not my faulty tablet, but something "normal" in wacom devices...

Yes, it is annoying. I wonder if there's any dev we can convince to write a remapping layer to fix this issue.

Hi to all. I am having a note 2, it has the same s pen as all the note series... i had that problem but it fixed when i did update! Try to go on developers options and check 'show pointer location' to check if the problem is the spen or the software.
I also notices that when used near the camera there is a great loss of accuracy .... and good to know that's not hte fault of my Note:good:

Mine just works fine, even on the ledges! Sometimes, but sometimes when the accelerometer is uncalibrated the S-Pen just stop responding well. I calibrate the accelerometer using this game https://play.google.com/store/apps/details?id=com.fgol.HungrySharkEvolution Just go on Options/Change to tilt control(If necessary)/Calibrate
It worked for me!

Thanks for trying to help .... the slight offset near the edges is no problem for me but i had a relatively bigger offset near the top (near the cameras) but that appeared to be due to the magnetic part in the book cover i had what an idiot .. i thought the camera had magnetic parts that do this and forgot the magnet of my book cover
So now what i really have is the offset near the edges
For me it's not an overall offset issue but just near the edges where it makes taking notes, sketching particularly difficult. It's very frustrating that these tablets aren't better calibrated out of box and provide no option for calibration. I'd be very surprised if this couldn't be fixed through software but would probably require support through the driver.
The other issue I have is that the drawing point only visually aligns with the tip of the pen when the pen is 90 degree from the tablet and you're looking straight down at it. Provided you hold the pen at a relatively steep angle and you angle the tablet so you're looking mostly down at it (say on your knee or a tilted stand) it's not bad. But once you deviate from that, say by putting the tablet flat on a table in front of you so you're looking at down at around 30 degrees, the deviation from where the tip appear to be and where the drawing point is becomes significant. I find this very frustrating. While I still prefer the s-pen to a passive capacitive pen, the fact I can't draw where I think I'm drawing makes it hard to work with. I've been using the tablet as my primary note taking device but I'm getting frustrated enough that I may go back to pen and paper and scanning.
It's probably not possible to fix this issue without hardware changes. Although multiple calibration profiles might reduce the effect.
I guess I'll have to wait for better hardware before I can finally live a paperless life...

That was it for me. The case was causing that. When I read your post I realized that my case has a keyboard and you can remove it. It stays in place with a magnet. So I removed it and it works as expected. so now I know to get it on the edges it's that. Thanks:good:
Here in China, was about to buy the phone.
I have seen several reviews mentioned the lense flare issue.
wondering whether this is a software problem or a hardware issue. Will it be fixed sooner or later?
Appreciate your comments.
Seems likely to be hardware related. I have only seen it once or twice and it has to be in the perfect lighting arrangement to really see it. I think it is being blown way out of proportion, it isn't anywhere near as bad as the internet would have you believe.

I've never seen it happen on my pixel and I take a lot of photos. Any camera will show flare if you're shooting towards the light... even my $4k DSLR..

I've seen it often but it doesn't look too bad. I'll attach a picture where it's caused by the backlight of my computer screen
I can reproduce it in certain conditions. For example, I can reproduce the halo on my phone when the light source is facing the opposite direction of the camera and I angle the camera precisely the right away. Aside from that, I've never had it affect any photos unless I'm intentionally trying to get it do so to see what's causing it. I've never had it show up in any of my outdoor photos yet.
It is definitely blown way out of proportion by people on the internet, IMO. It doesn't really happen to me unless I'm shooting right at the sun or a bright light source (which is kind of a bad way to take photographs in general anyway).
I have received my blue Pixel yesterday and thought that Google possibly did something to fix it and didn't expect my unit to have this. An hour ago, I was trying the camera out and was in the kitchen. When the light source was on left from me, then halo appeared, tilting/moving the phone closer towards the left(to the light), then halo started to diminish and after 15-20 degrees it was no longer affecting the shot. The halo thing is easy to spot and user is just able to turn a little and have a perfectly nice shot. I am personally not concerned about this unless the issues would be very severe and would appear in multiple angles. I think the back glass panel could be the issue.
Well noted, thank you guys for your response. will try to buy one from goole, ship to USA, then transfer to China.
Its just me or someone notice that the screen does move left/right a little bit?
Not much but still, that wobbling pretty annoying for me.

left to right? meaning on landscape, its normal because its the sliding behaviour.
but when it wiggles on both sides when in landscape. then its the sliding mechanisms fault.
i eliminated that using the Beatle case.

Same problem here... Very annoying but don't notice it with the case which is always on. Can't really send it back to China with a custom rom and get a new unit.
Just received mine and same issue. Not sure if I want to return it or not. I'm concerned it could get worse over time.
...its a slider phone...it slides
Haven't noticed that it gets worse yet. Constantly fiddling with the slider. Using a case you don't notice it at all.
Honestly can't believe this is actually a topic, it's a slider phone and for the ability to slide there can't be any friction (basic physics). So of course there will be slight wobble as is the nature of the design.
The Honor Magic 2 seems to slide without any wobble.

Hi,
Right there in France, my Mi Mix 3 wobble out of the box. A gap can be guessed between screen and body when hold through the light, may be half a millimeter.
Many people outlined this on Xiaomi forum, but not everybody knows this, others found it few weeks after use while fixation might loose a little.
Nevertheless, right now I can compare my Mi Mix 2 and my Mi MIX 3. The new screen is so gorgeous compared to the more yellowish and a bit washed Mi Mix 2 screen, and better balanced with its elongated shape. I am already in love.

When i try to focus on an object with wide lens the following artifacts appear. Even when i save the picture the halo is still there. Has anyone got similar results or do i have a defective device?

I just tried to replicate this with mine, but no "luck" - I don't see this effect...
But then I'm not in as bright surrounding as you seem to be is this effect always visible or only in bright lighting?
Just a thought may be that a lens protector (glass or plastic) could have such an effect....
I could only reproduce it on the beach scenery. Ill post a video to show you exactly how its reproduced
By the way no lens protector is installed.
Gif attached shows what my problem is.

Let's hope the woman in the GIF doesn't read and interprete that the way only women are able to interprete statements.
I have no idea about the cause - but I believe you still deserve an answer.
Questions: Where does the effect occur? Only in the viewfinder and/or in the finished picture? (I read your first post, still wish to make sure I got everything right.)
Does it happen with still photos or videos?
Does it also happen if you hold the phone horizontally (landscape)?
Which firmware version?
I tried to reproduce that fault although I had no ocean at hand - but never succeeded to achieve that effect.
Must be a software problem, maybe a firmware update solves it. Or a hard reset - but I don't like suggesting the typical manufacturer's helpdesk suggestion if they haven't got any clue but wish to get rid of the customer quickly.

Both viewfinder and finished picture. I could only reproduce it when the background was a beach only with wide lens. Ill try testing when the background is flat maybe in a field or something. I think thats the trigger with the halos. Didnt try it on video though. Firmware wise am on . 121.
And my woman should stay away from xda. For my sake

Due to the lower color depth, your GIF shows "banding", larger areas of the same color/brightness. Interestingly, it's one of these "bands" with gets replaced by white.
And if this phenomenon only occurs with a beach scene, it might be small areas of extreme brightness (like sun reflections in the water) triggering a software fault.
At least that's my guess. And that's why I mentioned I had no ocean at hand for trying.
Nokia's N8 had a similar, but not identical problem: If there were tiny spots of extreme brightness in a scene, the software rendered white circles or halos around that spots. Much smaller and perfectly circular, also the circles were solid white, not "just" rings like in your photos.
Maybe it's a similar thing with the P40 Pro.
The good news: It's a software problem which can be solved.
Didnt try it on video though. Firmware wise am on . 121.

Same with me. There's a lot of nuisances with the camera software, especially with the real bad, non-practical UI, but overall the P40 Pro really tops all of it's competition.
Let's just hope Huawei gets aware of the problems, soon.

There's no other living beings on earth being perfectly able to interprete nice words as bad words like women.
That's my understanding too. Ultra bright areas confuse the software. I reported it to their support team. Maybe there will be a fix. Am sure if more people will encounter it as soon as they go to a beach it will be reported and hopefully we get a fix. Wide lens on such scenery is a must anyways.
. 131 resolved this issue. No more artifacts
The punch-hole's circumference is noticeably jagged. Please zoom in on the image attached. You'll see that the boundary of the punch-hole circle is not smooth. Apologies if the image does not convey my point. You may check you own device's punch-hole on full brightness, on a white background to get the idea.
I'd like to know if this is the case with every unit of Pixel 6a or if this is normal.
There's also some very tiny amount of green-tint/rainbow-ish effect around some part of the circumference of the punch-hole, although it is barely visible and is probably just my eyes' fault.
Thanks in advance.
Are you talking about the pixels themselves on the display?
Pixels are square. The punch hole is a circle, so it's going to look like that if you zoom in enough.
We don't need no stinking laser...
Lol it does look a bit crude but then again I never scrutinize my Samsung's stupid hole that closely.
Mine looks fine and so does yours. Yeah if blow up your macro shot to 3x can see maybe not laser perfect but the circle is also cutting over pixels, so that's to be expected. I don't notice any rainbowing on mine

Run Screen Test to determine the color integrity of the pixels around the hole. Colors should be uniform. I always test the display on a new phone and as it ages.

An interesting thread. The flashing proximity sensor threads were common a while back. One or two flashing pixels on phone calls drove some Samsung users mad. Never even notice it before
Always a good idea to run Screen Test to help spot display issues especially on a new device or one that's under warranty.
I test my 3yo N10+ every month or two. It's bright so don't linger too long when doing it.
Any display pixel anomalies are easy to spot.
Any wrong color pixels at the hole would confirm you suspicions. With 20/10 vision and no magnification though the hole should seem smooth, at least on a N10+.
