[Q] Phantom Taps, Bad Screens?

Does anyone have a solution for phantom taps on your NC?
I'm on my 3rd Nook Color when I pick up the replacement unit this afternoon.
My general issues are phantom taps - or the NC doing things I don't want it to. So far a very poor experience when typing, turning a page in a book, or even just navigating the ui. The whole issue may be me, it happens regardless if I am plugged in or not. I keep a very clean screen so there is very to little gunk.
I do have sweaty palms on occasion but not out of the ordinary. I have other touch devices that have never given me this issue. If anything I think the screen is overly sensitive - hardware or software issue?

Nope it's not just you. Mine has a multitude of issues with the touchscreen...
Essentially I cannot use the touchscreen when the device is plugged into stock charger/cable as wherever I put my finger, a random touch appears somewhere on the x-axis near my finger.
It seems that the device does not like changes in temperature or humidity either when it is unplugged. Using my tablet while cold was impossible, and likewise while it had been warm.
I'm on my second tablet from Best Buy-- the first one had dead pixels galore (enough to make the best buy rep say "dang!"), and now this one has a bad touchscreen and hard to press power button.
However: I purchased one of these for my mother a few days before mine at Barnes and Noble, and it has no issues whatsoever... at least not yet.
I've come to the conclusion that this hardware is quite beta, but I'm willing to give them a chance since it is the best bang for the buck, even if I have to go through a couple of returns... it's honestly almost worth the time for me since a tablet is so valuable for schoolwork.

Fortunately mine does not do this. I think maybe for those that are having this issue it may be able to be fixed in a firmware update.
My EVO had extremely similar problems when it first came out with the touchscreen and not being able to use the dropdown menu while the device wasn't grounded. After a firmware update the phone was great with touch sensitivity.

my first one did this also. so far the second is doing fine, but the first didn't have any problems till the 13th day of owning it.
i'm hoping it's just an issue that can be fixed via software - maybe someone put an incorrect voltage input somewhere.

I was having the same issues. I bought a screen protector and that seemed to solve it. So far, it's been working fine.

I noticed the screen protector stabilized the touchscreen a lot. Before I seem to have a problem finding the sweet spot for a touch. Now it seems better.
However, my phantom pinky is always touching something while I am trying to navigate. As long I only get one finger near the screen, it's fine.
Mine came from B&N.
The only other issue I have is the magnetic clasp in the cover seems to throw the internal compass/magnetometer off a lot.

Considering the Nook has neither I think you are okay.

Then how is it managing to correctly position the screen with Google Sky? Is it just spooky smart?

Mine only has problem when screen gets dirty. Try a screen protector or use gloves.

is there really a compass in this thing? I just assumed there wasn't. if there is I'm buying another tomorrow!

Screen protector helps to solve my problem.

Are you seeing more issues right after cleaning the screen? I see issues then and I think it is because I an using some moisture on the cloth. If I just dust it lightly with a dry cloth and live with a few finger prints there seem to be less of an issue.

Oh well, it could be worse although I don't see how Google data can tell which direction I am facing.
Thanks dad!

Nor can your Nook Colour.. Using something like TetherGPS would have some heading information, but the NC itself without help would not.
It might show 0, dunno there. Maps for me just shows a dot, if yours is showing different, that'd be... interesting.
For S&G I tried "Compass", it of course FC's immediately like almost all apps that try to use the GPS. Enabled TetherGPS (with no server, just the client) and it ran, but of course no data, no heading, etc.

Is this occuring when the nook is plugged in? sometimes the charger can cause phatom touches with the touchscreen. Cleaning the screen and being on a stable ROM usually gets rid of that problem.

If only I weren't so stupid ...

LOL! Ok, I sat down with it and played for a bit. It appears some tilt sensor is handling the up and down tilt. If you raise the screen over your head, it shows those stars and if you tilt it down, I see what is below the horizon. That is pretty consistent. But it's also "simulating" a compass inadvertently.
By that I mean that if I happen to turn it on facing north, it appears to track as you turn in a circle but it's really just me tilting it and it's rotating he view. If you do it enough it has no clue the direction it's facing.
I'm just glad I figured this out before I got lost in the Amazon.

Just got mine plugged it in and unplugged and within stew minutes phantom touches couldn't even reboot it im on cyanogen mod 7

Useless S-pen

Hi guys!
I'm so disappointed with my S-pen on my Note!
I mostly bought it for the big screen(movies, youtube), and browsing. Both of these tasks are clearly awesome with it, but I never thought that the pen will be such a letdown.
All those youtube draw videos are fake, as it is impossible to use the pen properly. The actual line I draw is always misaligned a couple of milimeters to the top from the tip of the pen the way I hold it.
I realised I have to hold it in a certain way to draw where I want to which is not the way it should work!
It defeats the purpose of note-taking, e.g. using a ruler for straight lines or drawing with it, as the only time I don't move my wrist around is when I write.
The application found on the market(touchscreentune) to calibrate the pen requires root permissions, and I think it only works again for only one certain wrist position.
Now with all these above I can't see any use of the pen, so please tell me :
- do you have the same problem, or is it just me?

Hi,
Strange. For me its working absolutely fine and great. I just tried it again in S-Memo application and its working as it should.
I am currently on XXLQ2 rom and it was working fine also on XXLA6. Everything stock and never rooted.
Seems like your sreen calibration is wrong and I don't know what you can do yourself to fix it, sorry.

Mine works just fine.

Thanks a lot guys!
I have XXLPT ICS as well, never rooted or tempered with. Does it work for you perfectly fine when try to write with your pen from above? If yes, then it might be a screen issue for me and I need to replace it with warranty

If you root your phone you can install a tool to adjust calibration on the pen. Not all wacom digitizers or pens are exactly equal. Its odd that there is no calibration tool in stock GB or ICS ROMs.
Apps is called TouchScreenTune. Its a trial and seems to work well, but you have to buy to keep the settings. Its a $5 paypal donation.

Broken spen?

Hi,
I've started to notice that my spen doesn't seem to be working anymore. I never want first day that it is very difficult to use the pen for taking notes, drawing, etc. Wasn't dropped or anything like that, it just seems to of degraded over time.
I've tried it on stock market rom and cm9 and having the same problem. When I checked the pen on stock rom, by showing pen location on screen, it shows it (both when touching and above the screen), so it is being sensed.
Finger touch works fine so I think the digitizer works well. I also have a screen protector on, but I've tried taking it off and having the same issue.
Does anyone have the same problem?
Also, is there a way of increasing the sensitivity to the pen to see if that improves the problem.
Cheers,

I guess it must be due to minir wear-n-tear . You may try to OPEN and RESET at respective parts of your SPen.
I had posted a thread titled "Anatomy of SPen" on this forum, which might help you understand how to open and reset it.

Samsung Galaxy Note 5 S-Pen Sensitivity Issue

Starting a new thread since I could not find any existing thread on this and it is quite surprising since this is a widespread issue and for the same reason Samsung service here in Melbourne even refused to acknowledge this is an issue! There logic seemingly being if the issue is present in the demo unit in the store as well, it is not an issue! Vodafone has also refused to honor the warranty, even though it is in the first month of my contract and they should be replacing the handset and dealing with Samsung, and have instead told me to provide them with an acknowledgement from Samsung stating it is an issue! Talk about deadlocks!
Now coming to the issue, I have found out that there are sensitivity issues when using the S-Pen on the bottom right and left corners of the screen. There are issue on the top part of the screen as well but they arent as serious. I would also request you to check the same on your device and report back if you are also facing the same.
To check, first get into diagnostics mode by dialing *#0*# and then go to the S-Pen tab.
1. As you can see in the video, the bottom right and left corners have definite and serious issues with S-Pen sensitivity. I found this out, and it is also a use case and one of the major reasons that I went for Galaxy Note 5, while taking a screen grab from the middle of the screen right until the bottom right corner. I just could not do it. As soon as the S Pen reaches near the corner, the sensitivity issue makes sure that input isn't recognized. Not only this, even when it manages to identify the touch, the tracking is random with the S-Pen having a mind of its own.
2. The second issue is while drawing on the top part of the screen with the S-Pen but this one is not as serious as the first one. You can see in the video that S-Pen loses sensitivity in one particular area of the screen. This is easily corrected though, by pressing the S-Pen harder on the screen.
This is apart from the lag and slowness issues that rear their ugly head every once in a while and in a phone which runs an Octa Core CPU with a whopping 4GB of RAM. This is my first Samsung in a long long time and it has left me disappointed again exactly like it did in the past whenever I bought a Samsung phone. To me the level of polish of the hardware on a device costing as much as this is simply not acceptable. What are your thought? Please report in this thread if you are facing the same issue as I am with the S-Pen.

I have multiple stand-alone S Pens and don't experience what you're describing with them or the one included with the device.

Strange because I could replicate it on all the demo devices in the store. That is their reasoning for refusing the warranty as well.

I'll say this, the included pen is more responsive on the display than pens that are pre-Note 5 so something in the pen and/or display has changed.

Does it mean mine has a problem then? I am wondering if anyone else can also confirm the same?

I can confirm the bottom left and right corner of my note 5 behave just like OP's does... but wouldn't have found out if he didn't mention it

Thanks Alex. I found the issue because I could not take a screenshot which finished near the bottom corner of the screen. Now smart select is a headline feature of the phone and this hadrware oversight to be is just not acceptable. The Samsung service would not acknowledge it as an issue let alone do something about it. May be it is only on the first batch of phone. Who knows?

I checked my phone (SM-N9208 TW, mfg: will add later) and the bottom corners have poor tracking with the hover point flying off the screen when held above.
Overall this issue shouldn't affect the usability of the phone if you rarely use these areas since it's still possible though difficult to use the s-pen there.
Edit: I re-tested with my phone flat and s-pen vertical*. The s-pen can be used on the very bottom corners with precise movements, so I don't think will affect usability for most people most of the time.
*Having the s-pen on an angle can affect the tracking significantly as seen in your video. I think the only solution would be to modify the s-pen to track at the very tip. This would probably make the tip non-replaceable and/or more complex and expensive. If someone has time, try using the s-pen without a tip and see if/how it tracks.
Update: I tested a SM-N920W8 in store and it had the same corner issue.

I complained to Vodafone again and they decided to take the phone back. Back to trusty properly working iPhone 6s Plus 64GB. My last Samsung device no matter what the specs. I wouldn't be interested in one even if it will have a gazillion core CPU and few petabytes of RAM.

I have the same issue. Can anyone else, note 5 users confirm about this issue. (Bottom right hover issue)

I dont't face that problem
Edit: here is a screenshot
https://drive.google.com/file/d/0B5LZ1p_SFZ3faTFJNzBzZGlnbzA/view?usp=docslist_api

Mine does it a little bit.
It still passes the test so I believe it's within spec. I honestly don't see it being a warranty issue.

Sometimes, it is the Cover magnet.
Sometimes, it is the Cover magnet. . Try to remove you phone from it and try the s pen in the touch area in question. It worked for me with in a leather flip cover. The same for the s note stopping error message.

same here

if you have magnetic casing will get such problems ....
or fake s-pen need to replace with original or better fake quality

My stylus is overly sensitive; so much that I can't write properly. All text is in continuation even when I lift the stylus off for whitespace. I even followed the article on adjusting the sensitivity of the S Pen by removing the click-button cover and adjusting the Potentiometer. However, the note 4 s pen is entierly different as it doesn't have any Potentiometer under the click button. Link to article:
http://forum.xda-developers.com/showthread.php?t=2191333
What annoys me most is that I never had this issue before I flew overseas last month. I started experiencing this issue after I came back and it has rendered my s pen useless. Has anyone found a way to adjust Potentiometer on the new S spen yet (it might be located under top cap but i'm not sure how to open it).

I am having this same problem. Did you ever find a fix for it? Thank you!

Yes confirmation of problem
I found the same problem. If you try to draw a square in the S pen test mode you cannot draw a square in the bottom left or right corner. The square will turn into some kind of strange wiggle shape.
I live in Malaysia and went to the official Samsung head office service center and they confirmed this is a problem with all Note 5 models and the lady showed me her own personal Note 5 which had the same problem (actually worse than mine).
The service technicians said they do not know the reason for this problem. But as an electrical engineer I suspect there is some sensors in those areas which cause interference with the S Pen.

Note 9 S pen

Hello everyone,
I would like to know if anyone experience any issues while using their S pen? At times I would use my S pen to crop a picture but I noticed it would still move even if the S pen does not touch the screen it's hoovering over , also if I write a Note on my screen it will trail (if that makes sense). I tried syncing it again which fixes those issues but it seems like a temporary fix.

Do you have a magnet close by the phone? It interferes with the spen tracking
