[Q] Phantom hovering "taps" with video - Galaxy Note 10.1 Q&A, Help & Troubleshooting

I've noticed something strange. I suspect it is a software issue but I'd like to know if anyone else experiences it. When I make the s-pen approach the screen, the moment the tablet displays the gray "hovering" dot, it sometimes also makes a phantom tap.
Here is a video showing the problem: https://dl.dropboxusercontent.com/u/21246716/2013-04-28 00.27.41.mp4
In the video I'm hovering the pen in the app "Papyrus" with the eraser selected. Notice that no phantom taps are occurring if I move the pen even closer. It's "Pen too far away to register" ---"phantom taps" ---"Normal hovering" ---"real tap"
I'm using Android Revolution HD 6.0 on a n8010, with no special kernel.
Anyone else? I thought the pen could only "tap" when something touched the tip.
EDITED: Added video and removed the erroneous conclusion that it was only GUI related.

After a bit more experimentation, I now see it is not gui specific. The touch is just so slight I couldn't see the resulting little lines. The strange behavior has the following characteristics:
It only happens in some areas, mostly I notice it in the corners.
It only happens when the tablet first detects the spen. When you move the pen even closer, no phantoms taps will register. This is what makes me think it is software related. I could be wrong.

[Q]Text Area Troubles ICS-EOS-V1

Hello All,
I am not a developer and wouldn't know where to look for a sign of or a problem but I have one and wonder if I'm alone, and more importantly if there's a fix. Problem is this, when typing either using the stock android keyboard, thumb keyboard, or a Motorola bluetooth keyboard in a text area such as the one I'm typing this post into the cursor loses sync with the current position it should be in. The problem becomes most evident after backspacing to correct a spelling error for me. Also related is that after stabbing the screen and correcting a word and moving on, the word will just disappear. This phenomenon will also occur after selecting a suggested replacement and then stabbing the screen at the end of where I left off.It is extremely frustrating and very counter productive. I know that it would be a better solution to not have to correct errors, but hey... Sometimes it seems like I'm writing on paper and to correct an error I take a pair of scissors and fold the paper up, cut a snow flake out of it and then try to put the pieces all together again.
Anyone experiencing similar things and as I siad before, more importantly, is there a fix for it?

Touchscreen on P-5110 jumpy when using two fingers or more

Hi,
so the title just says all about it. When using two fingers (or more) to scroll and zoom around (for instance Google Maps), it is very jumpy. It seems to be completely random. There are days where it doesn't happen at all.
I have turned on this feature where it shows you the trace of your finger movement on the screen: Normally you could just draw two lines, each one with one finger. But when this issue occurs one of the lines just disappear or the both disappear and start from scratch. So it looks like the system thinks that I put both fingers up briefly and starts a new trace.
I hope you get what I'm trying to say, not a native english speaker
Ah, more info: The tablet is on stock rom. I use one of those microfibre textiles to clean the screen <- that maybe the problem?
Thanks for any tips!
Am I really the only one with that issue? Any ideas would be VERY welcome as this problem is really annoying!

Is it me or is the touchscreen of the S6 very sensitive?

Does anyone noticing that the touchscreen on the S6 is very sensitive. The screen registers my touches even when my finger is not physically touching the glass. I like highly sensitive touchscreen but it can be annoying especially when I am scrolling webpages.

I might be wrong, but I think since the S4 or Note 3, the phone has had the ability to detect when a finger was hovering over a particular spot. Though that is probably incorect because I only vaguely remember reading something about that 2 years ago when Samsung started introducing crazy features like scrolling based off of tilt and such.

Yeah I remember this feature on previous Samsung phones, but there is nothing in the settings that indicates that there is such feature on the S6.
Screens don't even work with the note stylist.
I agree, it is SUPER sensitive. For me, this is a plus, because I tend to be too fast for most touch screens, and the extra sensitivity keeps the S6 on par with my quick hands. I actually love everything about this phone, and I am very picky.

But, does your device have accedental touches when swiping quickly a webpage or an app?

I don't have mine till later today, but, on the S5, there are two settings that may be affecting the issue you are having. Can you still search the settings on the S6? Look for "Air View" (main culprit) and "Touch Sensitivity".

No, my device doesn't have accidental touches, but my fingers do. lol
The device can't make me accidentally do it, it's not a fault of the phone

Both of those seen to have been removed as user options.

I would like to see the touch response time of this device's screen measured. It's seems very responsive .
Yes it does and it's really annoying. To replicate the issue, scroll down a web slowly and then lift a very little like 0.5-1mm of your finger while you scroll it up. So scroll down and then lift a bit and scroll up without touching the screen. When you do this fast enough, the page will scroll up following your finger movement without touching the screen at all. Weird.
The Air View feature was removed on the S6, it was present on the S5 and Note variants. Same thing with the Screen Sensitivity toggle from the S5, Samsung just opted to make the screen more sensitive by default.
i have an S5 and S6 so I was able to compare.
I used the S5 for about a week and the touch screen was great
once I got the S6 I noticed i keep accidently hitting back/window button . upon tinkering and testing I realized the screen is super sensitive. If you take both the S5 and S6 (one in each hand) and lay them face down on your lap together, the S6 will hit buttons (and thus vibrate), the S5 wont
Hello,

Have that as well on my 1st S6 Vodafone EU 32gb.
Returned it for other reasons and will receive new one next week....
My touch screen was not sensitive at all, very unresponsive
I can verify that this indeed works:

I tried a reset, a full system restore, I tried safe mode, I tired uninstalling all apps, I tried screen tests and can verify for me, that this above solution was the only thing that fixed my problem.
Screen is working wonderfully now
Fix doesn't work for me?

I tried this and got an error message that this feature is not available on my service. I'm on US Cellular, I don't know if that matters or not. I saw this fix posted on another site and it seemed to work for a few people who were having the same issues that I'm experiencing. I'm not very technically savvy...do you actually dial/call this number sequence? How do I choose or command "TSP firmware update"? Thanks.
Some games are impossible to play because the screen is so sensitive it counts a touch as a swipe and some apps read as two touches. This happens consistently, not just here and there.

Not sure if it's just the way I'm holding the phone, but I frequently find myself turning on a timer, only to realise that I've paused/cancelled it like 2 secs after. Great when you put something in the oven and forget lol.

Touch screen sensitivity

Hello. I have an Nvidia Shield tablet k1 on lollipop 5.1.1. Everything is great about this tablet except the touch screen. It is really sensitive. Also, when I am scrolling, it "jumps" and goes faster than I actually scrolled. It scrolls faster than it should. I found this thread on xda. It helped a little with the being too sensitive issue, but scrolling is still really weird. This is my second device since the first one's micro sd card was defective. They both are like this. Is there anything I can do, or do I just have to deal with it?
http://forum.xda-developers.com/shield-tablet/general/adjust-touchscreen-sensitivity-t2963326
I was opening a thread with this exact same issue. I'm not on stock though (using the latest CM12 nightly), so I don't seem to have the 'Sensor Calibration' option.
Also the touchscreen seems to register a touch even when the finger is not touching the screen.
On the other hand, if I scroll a very small distance (like 0.5 centimetres) the list I'm scrolling doesn't move at all. This doesn't happen on other devices such as my Nexus 5 and Nexus 7 and is very annoying in some cases (some games, or moving the cursor for keyboard input).
I'll try to record a video of this behaviour.
What can we do to fix this?
Update: found a video (not mine) showing the issue I'm talking about: https://www.youtube.com/watch?v=08uPtusOJHQ
anyone else with this issue?
I also have this issue on/off sporadically on stock rom.
I'll be scrolling and itll jump back the opposite direction
Its like it looses track of the touch then catches it again.
It's irritating as my S5, Nexus 2012 have no problems scrolling smoothly.
I don't recall the original shield i tested in store to have this issue either.
Currently having amazon ship me a replacement to see if its just limited to the one I received. (QA issues)
Calibrating screen might fix the issues: go to About in settings and tap on model number until the calibration screen comes up. then hit calibrate. don't touch the screen then when it asks to reboot, reboot.

Did it fix the issue I posted the video about? I'm on Cyanogenmod now so I don't have the option to calibrate the screen, but I would consider going back to stock if it fixed this issue...
Calibration doesnt help at all , same issue at brand new k1. Nvidia says thats normal functionality lol
Yeah, very normal for a gaming tablet which would require precision...
Not trying to take up for this thing but I haven't had the first touch screen issue with it . so maybe not all is affected?? I've tried to replicate the issue but just can't everywhere I touch and slide is smooth
You mean it doesn't "jump" like the OP said? I don't seem to have that issue either.
I'm more concerned about the touchscreen's precision, as shown in the video.

OPO touch screen issue

Hi
I'm using trying to use the stylus and I get a weird behavior only on OnePlus One phone.
I've activated the "show touches" option in dev settings of OnePlus One, so I see the circle on each touch.
The issue is that the first time the finger touches screen and is moving inside that circle, the circle doesn't move. This makes all drawing apps not register any movement even though the finger is moving. Once the finger goes outside the circle, the circle starts moving and then even very small finger movements are registered by drawing apps.
This doesn't happen on Samsung Galaxy S3 and the drawing happens even inside that little circle from the first time screen is touched. This makes drawing apps very accurate even when writing small letters.
Do you know what might cause this? Is it a hardware or software issue?
I've tried to root OPO, install several mods like CM13, Sultan's mod, SlimSaber or Resurrect mod, didn't solve the issue.
Thank you!
Did you try to change firmware with another one?
I have the exact same problem too and I've tried every firmware every ROM every kernel there is. Sometimes a swipe turns into a tap too. I believe it's a OPO-exclusive hardware problem. It's the most frustrating thing ever
