I noticed an issue with the screen of the galaxy nexus.
-It seems that it does not regester the touch of my finger as good as my nexus s. " once you touch the nexus s screen very lightly you see a direct response. In the GN the light touches does not regester. Is that normal??
-Another way to test for it is using a stylus... the nexus s works perfectly with the stylus touch. In the GN you have to push slightly for the touch to register.
Finally.. when touching the keyboard very slowly... the button does not register no matter how hard you press. weird!
Have any one noticed this issue?

This simply scientifically doesn't make sense. If the nexus was a resistive touchscreen you would have to push hard, but, it's not. On a capacitive touchscreen it picks up the electrons in your finger, so, the lightest touch registers. It is impossible that pushing harder works better, that's not how the screen works. This is the case on the GPS in your car, not on your phone. It's probably your messed up brain ha ha jk

I know what I'm talking about!!. what I meant is: you need a larger surface area of your finger to touch the screen for it to register the touch.
there is a significant sensitivity difference between the GN & the nexus s
Here is a quick video demonstrating that slow touches does not register:

Personally, my nexus allows me to barely touch the screen to register. BUT, in past experience with capacitive screens, when my fingers were particularly dry the screen wouldn't register unless I put more finger surface down. I do a lot of wood working and all the saw dust really sucks the moisture out. Now, whether its the lack of moisture, or the capacitance between my dry static-y finger and the screen surface making mini lightening bolts, I don't know, but there was a big difference

This could be due to the fact your not holding the phone in your hand while interacting with the touchscreen, on nexus ones the touch screen/capactive buttons didn't work too well when the phone was placed on a desk and interacted with.

I have seen the same issue as the op, it is especially noticeable on the system soft keys where they require more finger surface area before they register the touch. The worst offender is the three dot menu key in the soft key area.
Hope they tweak the screen sensitivity a bit.

It also happens when I'm holding the device in my hand. I noticed that the lower screen is less sensitive than the upper part.
me too can confirm this issue.... it's like in the posted video:
trying to touch the screen on the Gnex sooooo slowly/lightly some times the screen don't take the input
you can verify in dev setting on the option that show you touch screen coordinate when you touch.... on the bottom of the screen you can see 'PRS' value (pression): try to touch so light you can the screen, you will never see number lower than 0,26/0,27 values.... now, if you can, try out on nexus s on other phone you have... you will see a very lower number. Lower is the number, better is the touchscreen sensibility.
and..... i know the difference beetwin capacitive and resistive touch..... soo, why can appen this issue to a capacitive one!?!?
p.s. i think this could be a software/driver isseu..... then could bee adjusted by a dev
there is app usefull for this problem, but only for Gnote/Gtab and transformer:
https://play.google.com/store/apps/...251bGwsMSwxLDEsImNvbS52aXRhbC50c3QubjcwMDAiXQ..
i think some dev can look into this and make one app for galaxy nexus too
can i make....?
Up! XD
To add to this. Overall theGnex touch screen is excellent. The driver seems to be configured to reject touches that are under a certain level of "distinction". If you slowly touch the screen and slowly spread the area of your finger skin over the screen, the touch is rejected. Generally it has stopped some inadvertant brushes, however if using the phone in bed holding it with one hand, it can be hard to use the touch since it can be hard in certain positions to be a bit "snappy" with your touch. It definitely seems intended.
yes.... thanks for the reply
i hope some dev can look into the driver and increase a little bit the screen sensibility.... as you had spoke, on the bed it's harder use the softkey.... and when i put my gnex in cardock it's the same....
you can try this app too it can change the sensitivity, minimum motion and duration to register touch. i have it installed and it does make the touchscreen quicker and more accurate for me. Need root for this one.

it seems only for samsung galaxy S....
yes but it's reported to work for the galaxy nexus as well. im using it with my nexus.
I posted this in franco's thread but it didn't receive a response.
http://forum.xda-developers.com/show....php?t=1559015
It seems you can edit the touch screen driver in the kernel for the Galaxy S2 and improve the sensitivity.
It has to be some sort of setting to ignore slow touches.
We have to find the equivalent driver code for the nexus. But definitely interested in this, looks like the solution we need.
Noticed this on my Galaxy Nexus as well. Thanks for the confirmation
did anyone find a solution to this problem? I tried the SGS Screen Booster app and i still can't get some touches to register. (i.e., the App doesn't seem to make a difference)
R: [Q] Screen sensitivity Issues??!!
Yeah i can confirm this!
My Nexus is D1 production (jan 2013) and i noted that in general bottom part is less sensitive than upper part!! Quite obvious in the corners and the nav bar. It is not linked to accidentally hit buttons, because you can try to rotate and that part will always be less sensitive.
Even in the upper part, my s2 is far more sensitive than this!
I hope it can be tweaked via software, but I smell crappy hardware here (Samsung Samsung....) because I already returned two devices.
Now that i know someone else noted it, I feel less crazy

Hey guys I just got my note 2 today and have been messing around with the S pen. Does anyone else notice that when pressing buttons on the screen to open apps or things in apps etc that it is not always responsive unless you hit it at the perfect angle? Also when I write normally i kind of write more at a sideways angle towards the screen but it seems to not register very well like this so I have to write more vertical towards the screen. Is there any way to fix these issues or is that just how it is at this time? Also i feel like if I write too lightly it doesn't register very well when writing. Is there a way to adjust the sensitivity or am I the only one who thinks this? Lastly, if i touch the screen with my palm it makes a mark in s note i thought it was not supposed to do this or let your finger write when the s pen is out. How do I set this?

I have a similar issue where i seem to have to press hard to get a reaction, especially the app drawer icon.
I notice you have to hit dead on which makes sense. This isn't a pencil or pen where you can write slanted and the ink still touch the paper or what not. But rather the "ball" of the s pen is where your main contact should be. Takes getting used to but what doesn't? Pen works great once you learn how it works

I had to exchange my S-pen 3 times due to sensitivity issue! One of them was way too sensitivity, I wasn't even touching the screen and I could write on S-note... Store manager thought that was part of the Note 2's new feature... lol
Even after the exchange of S-pen I was still having little issues with it, and I ran across a thread about slamming the S-pen on the ground. I know it sounds bizarre but it actually worked! I didn't believe it at first but now my s-pen works flawless... so weird. :silly:

lol like throwing it or just slamming it? and yeah i figured it would just take getting used to I just wanted to make sure it wasn't just my pen. So is there really no settings to change for it though??
Also funny question... does it matter which way it is held? Like when I was first holding it you would press the button with your thumb however you could also hold it so you would press it with your index finger. Does it matter? Is it made to work better one way?

Take a closer look at the tip of the S-pen. It's actually slightly spring loaded! I discovered this from an early review video I watched before I purchased mine. I believe that the tip has to be pressed hard enough to slightly retract in order to produce a mark. Writing with the pen at an angle may not be doing that.

Mom said don't smack
But I just tried it and the pen is working 95% better. I don't know if it will stay this way but it's working pretty well (for now at least).
stupid but it works for me.

Hey I have the same problem with you but I have solved it in a stupid but effective way. I open the back case and press it, that's it the pen sensitivity back to normal.... lol try it easy and effective....
The S pen can be too sensitive, so you have to adjust its potentiometer. Yes, you heard that right.Just pop the button cover off by simply using a razor blade or something really thin, the cover should pop immediately. Then, you have to use a small flat head screwdriver and turn the screw clockwise. This will adjust the S Pen sensitivity. If you want to make it more sensible, then you have to screw counterclockwise. You should adjust it until it no longer has a problem. This fix has worked for a lot of people, so it should work as a general fix. If you still have problems with the S pen, then you should get in touch with the dealer that gave the phone to you and get the S pen switched because it is faulty.

Wish I had known this a last week before I broke my last S Pen. lol Worked great and I even adjusted my full size S Pen as well! Kudos!
I noticed today that my S Pen does not actually mark where I touch the screen. This is not that significant in portrait but it marks and points a very noticeably 3 mm above where my pen is actually pointed. Is this normal or is my S Pen/ Note defective?

If you are a lefty make sure you go to the S-pen settings and set it for left handed use

I hoping you find a solution thats exactly why I moved from the Note 1 to the SG3 since it was driving me nuts. I had been told the Note 2 does not have the issue so I was going to get my Note 2 later this week.
If you notice, hover the pen above the screen and push the spen inwards with your finger it writes without even touching the screen.

I must say that if that was the case I would go to AT&T and demand they fix it or give me a new one! (Same thing if it wrote before I touched the screen!!) I just tested both of these things and it marks exactly where I place the pen, and does not do so until I am actually touching the screen! (very lightly!) I paid way too much (even though it was only 199 that is still a lot 4 me!) for it not to work exactly as I want it!

I think it may have been in an app I was using, because it does not go into landscape. It is still not exact but I think that is just the way it works for human error. It works as far as I am concerned. I will test more before running to ATT

Spen fix
To fix the hovering issue u can pop off the spen button with an exact blade or a box cutter blade. You will see two pentiometers. Having the top point to the left, use a fine flathead screwdriver and turn it clockwise an 1/8th of a turn each time or to ur liking. The left pentameter is for sensitivity of the spen. And the right one decreases the distance and sensitivity of the pen of it hovering above the screen causing it to write automatically. There are posts on this matter however I can't find the link anymore. Just Google it. "how to decrease sensitivity of spen for note 2.". I did this to my brothers and my own spen already and all is well. Note the button when prying out WILL fly out so watch your eye and do this in a well lit and clean Area. To put the button back on, just insert the side closest to the tip of the spen first then click in the back side. Hope this helps us guys.
I am having a problem with my Note 2 in general but in particular when in use the Spen that comes with the eraser. When u try to write about a quarter inch from the same left border the ink doesn't register. If I draw a horizontal like across the page I will get the first Harter in then it skips for about quarter in before resuming again.
I thought that is was just a dead area but when I change angles on the pen or use more pressure the line draws solid.
I tried a couple different tips but no difference. It is slightly better with the Note 2 Spen.
Ideas?

I have a similar problem. My Spen with eraser will only write in the middle of the screen, and eratically even there. The stock Spen works 100%.
Moreover, the Spen with eraser works fine on other Note 2s.
I called Samsung about it, and they eventually gave me an rma number for the phone, but I am not sure if I'm going to send it in. No guarantee the replacement will be any better.
Btw, this is all after trying the porentiometer adjustment.
It must be a Sprint Note 2 thing.
My Spen eraser does the same thing.
I ended up getting the Spen kit for the Note1 and it works great. It also feels much more like a real pen for me.
I found this thread doing a search, I usually hang over on the VZW part of this forum. I also have been having the same troubles with the spen with eraser. I changed tips and that made things even worse. Question for those using the spen kit for note 1, does the stock spen for the note 2 fit in the barrel of the pen holder in the kit?
I looked at the tips of the stock spen and the spen with eraser and they are shaped differently. My spen with eraser will work if I hold the spen completely vertical to the screen, but how often can I do that? I am usually in a hurry to jot something down and do not have time to put it on a level surface and hold the pen vertical.

I don't use my S-Pen too often, but since yesterday it becomes too sensitive it start to draw before I touch the screen.
I tried my spare (purchased separately) S-Pen and do exactly the same behavior.
Any clues?
My note 2 is Un-Rooted.
No changes, no drops, same LCD protector, no magnets.

Got the same issue and resolved it by hitting several times the stylus on a surface that won't damage it like a pillow or your hand if you can bear it. Hit firmly but apply reasonable strenght though. Repeat until issue is gone. To clean the stylus may help too.
It can be your tip of the pen that's stucked...

It's very common. you'll need to adjust the potentiomenter on the pen. See here

That worked, but seems I'll need a new S pen, this one now is all time as eraser

I believe you can adjust the sensitivity of the pen by removing the button on the s pen and adjusting the screw underneath.
