Recalibrate touch screen? - Nexus 7 (2013) Q&A

Maybe I'm just retarded, but I can't seem to find the setting to recalibrate my screen.
It's been slightly annoying me because I bought one of those fancy adonit styluses, (The ones witht he plastic disc, supposed to be more precise), and it works great, however when I turn on the "show touches" function, the touch from the stylus ALWAYS registers slightly towards the edge of the screen.
If I touch in the center of my screen the touch registers dead on, but the closer I get to the edge screen, the further off it gets.

I've noticed something similar on my tablet. But in my case, the best alignment when showing touches is in the upper left corner of the screen. As I move farther down, the touches start to come up slightly down and right of where the stylus is touching the screen.

So It's been a couple of weeks and Ive still yet to find a way to fix this slightly annoying accuracy issue. Does anyone know a way of doing so?

Improperly grounded touchscreen?

My capacitive touchscreen has been having a pretty odd issue. If I lay the phone on a bed or desk and try to use the touchscreen with only one finger, I get all sorts of weird input on the screen. Then, if I touch the phone casing while repeating the same motion with the same finger (anywhere on the side of the casing or rear panel) the touchscreen works flawlessly.
Right now, my device is sitting on my bed, if I unlock it and try to pull down the notification window shade with just one finger, it's impossible. If I touch the casing with another finger and then try to pull down the shade, it's flawless.
From my understanding, in a capacitive touchscreen, a layer of electrons (ions?) is passed over the screen and a sensor detects where the flow of electrons is interrupted by the electrical conductivity of the human body. It seems that my phone is having issues with the electrons not just flowing over the screen, but around the casing as well, causing issues.
Anyone else experiencing this?

This appears to be a significant issues of owners of the HTC Incredible. You might get more useful information in that board, seeing as how they've been experiencing it for much longer than we have.
Wow, the video that they have on the Incredible forums of the phone on the Styrofoam is exactly the same issue I am seeing on my device.
I would link it, but apparently new users aren't allowed links. Ugh, this is a real bummer. Especially since that guy had 2 replacements sent to him, both with the same issues.
I too am experiencing this. I want you to try something a little different. Pull the kickstand out and stand it up on the bed. Then put your finger on the kickstand and you should be able to pull the notification bar down all the way to the bottom and let it lock with your other hand while still keeping the finger on the kickstand. Then take that finger off of the kickstand then slowly bring the notification menu bar back towards the top with your finger. Tell me your results. And i'll let you know if we had the same.
It appears that HTC has got some serious quality control to enforce on their recent devices. At this point, releasing a flagship phone with these issues is nothing short of unacceptable. I'm as big of an HTC fanboy as they come, but I'm really considering switching loyalties to Motorola is this crap continues. It's bad enough being capped at 30fps on the Evo.
If I put my finger on the kickstand I can pull down the notification bar completely, without issue. When I let go and pull the bar up, it works, but looks like it is trailing behind where my finger is by about a half inch, until I get roughly 3/4 of the way up to the top then it passes my finger like i'm not touching the screen anymore.

That might be the touch input lag we're experiencing as well. This may be tied to the 30fps graphic limit on the Evo.
The 30 fps limit is disconcerting, but that seems like it is something that could be fixed through firmware, however I doubt this issue is fixable.
Yeah, that's the exact same response I received from it; except when going back up, i reached the 1/2 way point on the screen and the notification bar shot up.

Well this is slightly depressing.
Ugh, my curiosity got the best of me, and the results aren't pretty.
When I lie my Evo down on a flat surface, the notification bar becomes absolutely impossible to pull down unless another finger touches any part of the phone. A test on the multitouch visualizer app shows that the screen completely stops recognizing my finger when y1 is equal to 40. This is essentially the entire height of the notification bar.
This isn't a deal breaker in any way, but what the ****, HTC? Is this how you treat your customers?
On mine, my screen becomes effected as early as y=500, then gets really bad around y=250, then is completely unresponsive after y=100.

wow, that blows, mine does the bad response -40 thing. holy ****, it's really just one thing after another with these phones...
I guess there is no such thing as a perfect phone no matter how much money, research, and time is invested into it.
I too have this issue, I have noticed occasionally its hard to pull out the notification bar, but when I pick up the phone and pull bar with other hand it works perfect.
For the heck of it I tested my Evo on every surface i could my hands on from glass, to thick carpet, bed sheets, etc, etc. Mine doesn't seem to have this issue, so it's definitely not every phone. If it's a big issue for you, you may want to see about getting it replaced.

Thanks for the thoroughness of your test!
http://www.youtube.com/watch?v=_kJ_fR02suQ i recorded it so people can see what's going on.
Have any of you contacted Sprint about this? I'd definitely try to get it replaced ASAP if I were you, hopefully the next one won't have this problem.
I spoke with a lady from HTC today and she said that they were aware of the grounding issue before it was released (during training). She didn't say whether it could be fixed or not though.
mine works perfectly fine i just tested it right now

[Q] Xperia arc screen too sensitive?

Hi all,
I simply love this phone, but I'm facing a situation that my screen is too sensitive. The home screens were so sensitive a few programs were started without my knowledge. It got better after I switched to Launcher Pro.
However, it is still too sensitive in other areas. When I'm scrolling down, say, the apps in Market, I'll always end up selecting a few items accidentally before I reach the end of the list.
I've used HTC Desire in the past and I'm quite sure the problem is not due to me.
Does anyone else face the same problem, or I have a hardware problem? Or software problem? Can I be tweaked by any means?
Any feedback would be useful! Thanks!!!
KG
I faced this problem before... while swiping, apps accidentally open. But instead of "too sensitive" i thought it's insensitive... because a short swipe was sometimes interpreted as a tap (maybe because the swipe was not fully detected?).
Anyway, I had 2 layers on my device... the pre-applied sheet and another screen protector that came with the box.
I removed the second layer, leaving only the pre-applied sheet, and all is well again... no more accidental "taps"

Dude, you mean the cause was the screen protector that came with the phone???

For my case, maybe 2 layers is just too thick
I'm having the same problem. And that solution seems to make sense. I would give it a try, but if the problem still occurs, I'd be wasting one screen protector..

That was how I solved my problem. I actually put on the spare screen protector because when I got the set I didn't realize there was already a pre-applied layer.
Don't blame me if it doesn't work for you
perhaps some of you guys just have the shakes?! ;-p
I guess the screen is never to perfect for everyone.
kargtan, I've noticed the same about the tap sensitivity - I often accidentally "tap" when I mean to swipe. Came from an iPhone 3g and didn't notice this on that device. Might be a matter of getting used to it, not sure. Have you gotten any feedback from others in other forums?
I've noticed this too, and put it down to the screen protector. It's not android OS causing it, never had the problem on my htc hero...
However, now that i've gotten used to the phone it doesnt do it any more - guess my brain has automatically trained itself to drag the screen a little bit more firmly or something.
One thing i have noticed about the arc is: because the bezel around the screen is so thin, i often accidentally launch apps just by holding it. My fingers wrap around slightly & touch the edges of the screen.
Does any of you have problems while trying to swap a screen from another and instead of swapping you get like a "bounce" and stay on the same screen? because that happens to me all the time, I came from an htc Legend and this is making me crazy !
btw, this happens to me if I hold the phone with my right hand and try to do the swapping with my thumb, the only way to get it right is to hold the phone with my left hand and use the index of my right hand
Screen too/not sensitive
Hi guys,
I think the problem arises from the slowness of the phone, not "too sensitive". I used to use the HTC Desire in the past and I was very used to the screen scrolling very quickly. In contrast, the arc is slower and hence the screens don't scroll as fast and hence my way of handling the Desire would cause the problems stated.
I did a few things since my last posting and it seems better now:
Replace the SE Home with Launcher Pro - this seems to have improved on the speed of the phone, and hence better responsiveness to the touch.
Rooted the phone and uninstalled some stock programs.
Removed useless widgets on the desktops.
Adjusted my way of scrolling as someone has suggested.
This is quite frustrating at times, especially so because other than this problem, this phone is a gem, especially its form factor, the sound quality and most importantly, the quality of the camera.
I might sell the phone once the company issues me with a Blackberry (DANG!), but I am kinda unwilling because I have been taking lots of photos with my Android phones and these photos are generally well-liked by my Facebook friends.
agree with bezel thing and hard to use thumb.
noticed arc screen (the screen guard perhaps ) easily get oily and slippery.
had to wipe phone and wash hand so often that make me like some sort of disorder.
Don't know why you guys seem to be having problems... I don't have any issues with my screen swipes at all... smooth and fast.. both on stock and Launcher Pro..
Same deal here. But that's because the screen is sensitive beyond the display area including the black border, and the edge is too narrow. When I use one hand swiping or tapping, the palm of my hand touches the black border. The screen registers two touches in quick succession and thus jumps.
In Phone keypad, enter *#*#7378423#*#* (the numbers mean SERVICE word in keypad), you can go into test mode. Select [Service test]->[Touch Screen] to test the badly touch screen of SE Phones.
You will discover when you swipe the edge of touch screen, the touched result is very not satisfied. The lines you swiped will not accurate and appear like jags, or stick on the edge of the screen.
The touch panel made in China...? ;-)
Me too!
Hey!
i also have a xperia tipo....and i too have the sensitive problem
Could also be a kernel problem?
I remember I installed a kernel a while back that would make my screen hypersensitive; just hovering over the screen would already activate it!
I don't remember which one, it was back in the GB days. But I'm pretty sure it can be changed in the kernel.

[Q] Capacitive Sensor Boundaries?

So far my new zenwatch has been great. However, I have noticed in a couple apps such as Multi Calculator for wear, that buttons at the bottom like . and at the top like ac/c don't respond very well. Then I noticed that throughout the entire watch interface, the top and bottom 1/4 of the screen (not the bezel) are entirely unresponsive to touch. I wanted to see if this was a defect or possibly a byproduct of that curved glass not allowing the capacitive sensor to extend beyond that middle portion of the screen. Does anyone else notice this?
I've mostly been marking it up to bad aim on my part but it seems to me that I often miss touches in the upper right corner. Too soon to tell if it's the watch or just my shakiness.
Yeah I thought my aim was off too. Try dragging from the top on the watch face screen. You'll notice it actually starts to pull it down a few millimeters from the top. I was hoping it was a defect so I could just exchange it but my fear is that they all do it and it is not fixable via software.
I agree that the first couple of millimeters of the actual screen don't respond but nowhere near 1/4 of it.
I notice this on my zenwatch after using an lg g watch, g watch r and moto 360 all side by side. The zenwatch also seams less accurate on thing nlike minuum keyboard and generally with scrolling. I suspect a cheaper less accurate digitizer has been used?
On mine I can hit the topmost part of the screen, the bottom, and all corners. I turned on "Show touches" in the developer options to make sure it registers where im touching. If you test it that way, you can see if its a defective screen or just accuracy issues.

Touch too sensitive! issue?

I've tried to change the touch feedback setting to long/medium/short but nothing changed.
I attach a video that show what is the problem with the screen/digitizer - when tapping and keep touching (holding) the screen look at the X axis - its not constant as it should be.
The finger hold stable and not moving, but at the screen the dot moving.
I've checked 3 other G4 devices, all of them don't have this issue.
There is no screen protector (neither the one that comes with the device)
Most of the problem is at the top left of the screen, the bottom right is pretty stable.
Its very annoying while use brush/paint, zoom pictures, playing horizontal mode the left side (top of the screen) dosn't work because of this on some games.
Anyone else had this issue?
What is that problem and how do I fix it?
Is it a software / hardware problem?
There is something to make it better? anyone notice this issue?
My g3 was real bad like this it was software changed from kernal to kernal. not really rom to rom. And g4 is horribly over sensative
I have the same problem, for me it's probably hardware and software, because it was better before V20D, but I still had the problem, now it's worst. LG tried to hide this ****ty screen with software. But I repeat it's first an hardware problem... All my left screen is bad and not stable, more than yours.
Try the app "Ghost Touch Tester" and in developer mode activate "Show Touches"
This is very disappointing, reminds me the first android devices at 2010 with the bad touch screen.
Its not that worst, but you expect a smoother and better quality for device on this level.
I guess its a hardware issue, 2 other devices that I've checked dosn't have this issue (of too sensitive touch) even with tempered glass screen protectors.
The left and the top sides are most sensitive then right buttom.
Maybe kernel would fix it, anyway same story with ver. 5 and with the new 6.
Any ideas if there is something to do?
Have a 2 years warranty but I believe they "won't find any problem".

My g4 is pretty bad when trying to type i mispell all kinds of crap and i got the glass on too
My G4 is very difficult to scroll with. It constantly opens links, instead of scrolling. Tried changing the Acessibility settings for response time to slow, and also the pointer speed, but it didn't work. Very frustrating. I almost wonder if someone paid LG to make sure more links get opened. Seems kind of convenient that the end result is you click on almost every single link.

active stylus partially functioning.

So i bought the a50 cause i wanted a bigger phone like the note at a cheap price. Loving the phone, so i decided to spring for an active stylus, the stylus actually works very well on my g6 and dell touchscreen but for some reason the upper half of my a50 isnt very responsive, and where it does respond is only on the edges. If i start a stroke from the bottom of the scren it will follow through to the top, most of the time. But if i start at the top and move down, it only appear towards the bottom off the screen. Tapping is even worse, almost no response on upper half.
I have no magnetic cases, ive tried two a50s, with and without screen protectors. Always the same result. Heres some pictures to help visualize, does anyone have a fix for this?
Scribles represent dragging, dots represent taps.
You could try increasing the touch sensitivity.

Thank you for your response. I should have mentioned, the problem is identicle, with or without touch sensitivity increased. The stylus work on a note 9 perfect as well. Starting to suspect its a software problem with the a50.
