[Q] Touch Screen issues. [SOLVED] - Nook Color General

Ok folks, I registered here because I felt this forum was the best place to get help. Here is my problem. I use a Nook Color 1.1 running the latest autonooter, and I've started having major touchscreen problems. What happens is this: The screen has started registering touches when I am nowhere near the screen, and when I do touch the screen, it only sometimes registers at the right location. This has made it impossible to use at all, and I'd like to know if there's any way of fixing it without having to do anything on the Nook Color. Thanks for your input,

Reboot? Wipe the screen? Reimage?
Sounds like damage to me.

Clean the screen thoroughly then reboot. Does this fix the issue, even if only temporarily? If so, buy a matte screen protector. The NC screen has a tacky coating that seems to collect oil/moisture more than other screens I've used.
If that doesn't work, download a screen calibration app. There's one floating around the forums.

I had the exact same experience when I first tried to install CM7 to run from an SD card. I couldn't sign in to my Google account because just hovering my finger over a key produced a string of letters on the screen (ie: yyyyyyyyyyy)
It was really freaky. I had to sneak up on a key and jab it real fast so that it would type only one letter.
I also had a problem with key registration. I would go to type an "r" and a "t" would be typed. So I had to touch the key at the extreme left edge (or sometimes on an an adjacent key!) to get the letter I wanted to show up.
Fortunately, after I got CM7 up an running properly, the screen problem went away. BTW, I do use a anti-glare screen protector, which, I think, lessens the screen sensitivity a little.
If I were you, I would try restoring my Nook back to stock, and see if the screen is still too sensitive. If it is, it's time for a new Nook. If it's not, try rooting again.
Good Luck.

Try Nook Screen Recalibration on the market. I had the same problem (pressing Q gave me W). It certainly improves it.

use a screen protector or put a thin plastic sheet on your screen and then recalibrate it.
using the method given here.
http://nookdevs.com/Recalibrate_the_NookColor_touch_screen
If you are using a screen protector u can keep using it, however i removed mine after a week or two and didn't really get any weird touches what so ever after that (earlier my touchscreen was unusable).

Thanks for all your suggestions
Thanks for all your suggestions. I think it got worse after I used a recalibration app from the marketplace. For those suggesting I try an app, I can't get the NC to settle down enough to let me tap on things. Yes, I do use a screen protector, so that's not an issue. I will try recalibrating from my computer, and if that doesn't work, is there a good tutorial on how to put it back to stock, and is there a way to re-stockp) it so that if I DO need a new one, I can just return mine? Mine is (if I hadn't rooted it) still under warranty.
TechPlease

Seems like it's fixed.
I think I got it fixed. It calmed down enough for me to run the Nook Screen Calibration app from the Android Marketplace again, and that seems to have cleared the problem up. Mods, please (if you can) mark as SOLVED.

If I connect my nook color to AC adapter, touchscreen will response randomly , so I unplugged usb cable and touchscreen works again

WSOD! Help!!

My tilt is acting very nasty lately. Over the past few weeks, I noticed that when I turned on the display, occasionally I would get something that looked like the static that you see on TV, but with colors. I would just turn off the screen, and turn it back on to clear it.
Now it's gotten worst! 98% of the time, it intermitantly gives me a blank solid white screen when I turn it on. Occasionally I can just turn to screen off, and on to reset it.
I'm running OEM WM6.1, and I've tried to reinstall the OS, but it didn't help. My phone has taken a beating, and the top corner has had a small crack in it over the past 2 months, but it didn't effect the touch screen, or picture. I also took off the cover to make sure the cables were all snug, and it didn't help.
Any suggestions?
Something got corrupted. If you search WIKI, it's call the 3 color screen stuck .. and you're better off posting at thread below. I hope someone can give you help (if you follow those steps and still no good)
As rule of thumb, do a lot of reading first
http://forum.xda-developers.com/showthread.php?t=423486
On a second thought, it might be the LCD itself broken ..
Oh, believe me.. I'm not one to turn to the forums without doing research myself! All the research I was coming up with seemed to point to a slightly different WSOD though. I think you are right about the screen being broken. I've reinstalled the software, and it acts up even when booting up!
Unfortunately, I'm not impressed with ANYTHING on the market to date! If I'm unable to fix this, I'll just go back to a RAZR until the next gen WM7 phones come out. (With a tilt screen of course!!)
Oh, and even though the screen goes white, it's not stuck, as it fully boots up; I can hear sounds, and even activate the touch screen.
Also, I forgot to mention.. the first problem I started experiencing was that my tilt would go back from landscape mode! It was like the video board was crapping out. I could even see a slight flicker in the display from the refresh rate.
hi i think you may need a new Need a new flex cable ribbon as i had the same problem once
Thanks Tayzaa, I think you could be on to something. I'll open it up and take another look!
Hi!
is this problem solved?
WSOD is bug of Hermes. I would know if kaiser have the same WSOD-bug with D-pad?

Screen alignment problem

Hi all,
I recently bought a used X1, wich already had a custom OS (Christian's) installed.
It's an excellent device, though there is one thing that really pisses me off.
The screen alignment is off all the time. No matter how often i re-align, after a short while it always is a few milimeters of, especially on the top half of the screen. So, for example if i want to press a button, i have to press above or under it, else it doesn't work.
I already tried cleaning the edges of the screen, even with pressurized air. Didn't help though.
Is there any solution for this or have i just been ripped off by the seller of this device?
Btw, excuse my english .
Can anyone help me please?
I mean, i really love this phone. But the touchscreen issue makes it kinda useless to me.
Is there any fix for it or is it just the way it is untill i replace the screen?
Hard reset. Or re install the ROM
Make sure to take your time while aligning your device, get some very precise points in or it will throw it all off. If all else fails you can try re-installing, but that probably isn't the problem if realigning fails. Possibly a screen issue?
I hard-resetted (?) and reinstalled the os, didn't work though.
When i re-allign it's all ok, but if i go to 'notes' then, and draw a little, it quickly becomes mis-alligned again.
The line is sometimes drawn more then a centimeter below the stylus :S .
I assume this is not a software problem, perhaps the screen is broken?
Anyway, i'm selling it back to the previous owner...
when i had a problem similar to this it was my ribbon cable that had worn away with sliding the keyboard in and out.

Screen issues

Screen looks great. But I'm having two issues.
First, the screen feels kinda rough dragging my finger across. By comparison my Galaxy S phone and iPad are very smooth and glide with no resistance.
Is this normal, can it be improved?
Second, the screen seems unresponsive at times. I'll have to tap more than one to get it to recognize an action. Maybe it's just being slow.
Also the calibration seems to be a bit off. I often seem to be clicking items below what I tapped on. Not sure it's completely user error since I don't seem to be having this much trouble with my 4 inch Android phone.
PS. The phone is rooted with AutoNooter and using LauncherPro and Dolphin browser.

My screen is very smooth, and a little bit tacky... I'd prefer a less tacky, smoother feel, but it's okay.
Unresponsive I've not noticed really, but the calibration on the edges and/or corners is funky.. Like hitting the Search button in the market is hit and miss, otherwise other places I personally haven't seen any issues.
There's a thread on here / directions on nookdevs for how to recalibrate the screen. A lot of people have been reporting issues with the calibration on the edge of the screen. It doesn't bother me too much, so I haven't tried, but results are apparently quite good.
http://www.nookdevs.com/Recalibrate_the_NookColor_touch_screen
I've recalibrated the screen a few times. Even did the suggestion with placing the Nook face down for extreme sensitivity.
I still seem to be having the same problem where the touch is very unresponsive. It's most noticable browsing the web, I'll have to tap links multiple times before the browser does anything.
I'm wondering if I have a bad Nook or is this just how it is?
It could be the default browser. I had problems with unresponsive tapping as well but after switching to Dolphin Browser HD I havent really noticed them at all. However, it does seems like only certain apps or portions of them have problems with touch response...I can think of 2 off the top of my head..
1) The search icon in the Android Market. I have to really tap it hard or multiple times for it to open the search ability. Everything else in the market is a light, smooth, responsive tap, except the search ability.
2) ADW's settings menu, specifically the back button. Have to really hit it hard to work yet everything else works perfectly fine.
Maybe it's just me but I swear its only certain things which respond poorly to taps.
In regards to the screen being tacky, goto B&N and buy the Anti-Glare protective screen film. Make sure its the anti-glare one and not the regular screen protector. Not only will your fingers slide perfectly, but it also avoids all the annoying fingerprints the default glass seems to collect. Worth every penny. (You get 2 of them for 15 bucks)
I find that I have better luck ith a light touch & avoid a "tap". It took a bit of practice to know what part of my finger was actually making contact with the screen first & the reason for the perception that the screen was out of calibration.
I do have a problem with the center right area of the screen when playing crossword. Sometimes it is very hard to click on the rufgt side boxes. Interestingly, the same area of the screen is responsive in other apps.
Cheers,

heers,

I purchased the matte screen protector from them and it alleviated the tacky feel of the screen. Also resist oils and smudges so its a must have in my opinion.

I have the same problem at the very top edges of the screen. Pressing search in marketplace or a new tab in dolphin is really annoying. Requires many taps to work. Rest of screen seems to work fine. I did notice that the 2.2 Froyo was way worse for screen sensitivity. Maybe they can fix somehow with a firmware patch or something.
I have the same problem. Will try recalibrating later.

I don't think the market search button issue is a screen calibration issue. I initially thought there was an issue with the sensitivity/calibration in the top corner of the screen, but I have the same problem with market search when I am in portrait or landscape. Touching items in the same area of the screen in other apps is fine.
My screen is definitely more responsive after doing the commands.
I made sure to clean it completely with a microfiber cloth before running the commands.
As for the market search issue, it seems to have improved the sensitivity. In fact, to me it now feels as if I am getting the button push through, but it just takes time for the app to register it and take action (lag) and thus we think the button push did not go through and push it again...
my 2¢
A lot of the discussion on this thread is for locale based calibration, but I had the issue where if you hold still on a drag and drop, before dropping the thing you are holding is jittery, as thugh your finger was being jittery. This calibration fixed that problem.
Under the thought that this might happen again, would be nice if there was a way to run the command locally on the system without having to connect to adb to recalibrate.
Any ideas on how that could be done? I was thinking maybe scripted terminal commands?

[Q] Touchscreen issues. Replace now or wait?

Since day one, I've had touchscreen issues. When the charger is plugged in, the keyboard is unusable. One touch triggers keys all over the place faster than I could ever touch the screen. Unplugging the charger fixes that issue.
After a while, phantom presses start happening. If an app supports multitouch zoom, it becomes impossible to scroll instead of zooming. Keeping the screen clean seems to delay the problem from happening. If the problem presents, just cleaning the screen won't help. I have to turn the display off and back on for any effect. I've heard putting on a screen protector helps with this issue, but I haven't had a chance get one. If the screen protector just masks the issue, that doesn't seem like a good fix.
Should I try to get a replacement Nook Color now that doesn't have these issues or should I wait until the last month of my warranty to see if I can get more developed hardware? There doesn't seem to be a consensus if these issues are hardware or software.

That must be frustrating. Mine does not behave this way at all (though I've only had it for 4 days). If you bought it in the store, I'd exchange it. If you bought it via the BN ebay store, I'd try the screen protector first as I hear it's quite an ordeal returning it via ebay.
This us a very common issue. It has something to do with sensitivity of the screen increasing greatly when the unitbis charging or the screen brightness is way up. I just chage mine at night and don't worry about it.
I was having a lot of problems with phantom touches -- I even replaced my 2nd NC just to get another one that had the same issue. I ended up putting on a B&N anti-glare screen protector and haven't witnessed any phantom touches since then.
Edit: I actually meant to post this in the other phantom touches thread. ;/
Happens a lot to me even while unplugged. Known issue. Until I pick up a B&N screen protector I find locking the device and a quick wiping of the screen with a microfiber or any soft cloth (my shirt works in a pinch) removes moisture and oil build-up that is causing the uber-sensitive digitizer to register phantom touches.

[Q] Screen sensitivity

I am not sure whether it is my mind playing trick with me or not, but I feel like my phone is less sensitive after I did the hard reset (power+volume down). Sometimes I need to press 2-3 times because the first light tap was not detected.
So is there anyway to increase the sensitivity?
I have the same problem, but no idea that is the hardware or only software problem.....
Fresh owner of this Optimus 2X in France, in our community, frandroid.com, we encounter the same problem , I think this is a software issue.
Did someone already contact LG??
Maybe they should include this into the bug list thread.
May I know were you guys having this problem since it is out of the box? or after reset?
I have the same problem started from day 1 till now
I have the same issue and already thought I'd be the only one having this problem.
I would not say it's a problem with sensitivity, but it feels like the touchscreen goes into some kind of sleepmode where then you need to press a second time, to wake it up.
Continuous touching is no problem. (like when typing rapidly on the keyboard)
This video is not from me, but it shows the problem.
Have a look at 13:28 and 13:37. The reviewer tries to hit the "Ackermann" entry, but the touchscreen does not recognize the touch. At 13:37 the guy has to press another time to get the entry selected.

Yes! The touchscreen is definitely less sensitive than my old HTC Hero, and gets quite frustrating sometimes when a scroll misses the first part of the movement or a click is missed.
Sent from my LG-P990 using XDA App
just in case, are you guys using 20110218 baseband too?
The same problem here. If I unlock the screen and then tap on any on screen apps, I need to touch again for it to open. Only the first time though, after that it function ok. I think this is a bug and needs to be fixed... I have my pc for double-click.
Yep, count me in. Same problem here. Sometimes screen taps aren't registered. Will do some research later on, but I think it's a software problem. (maybe you have to tap 2x as fast )
Hi,
same problem here!
Potentially a driver issue. A Nexus S user had a similar issue in this thread: http://forum.cyanogenmod.com/topic/18431-tuning-driver-to-deal-with-unresponsive-touchscreen/
He managed to tweak the driver and it works fine now. Need to know C++ (I think?) to understand though.

I see, then probably they will fix it on the next update/gingerbread?
Same issue here.
Correct me if I'm wrong, but the problem seems to be that the screen has zero tolerance when it comes to tapping and swiping together. If you tap and slide your finger a bit directly after the tap, the tap is ignored. In other words your tap has to be a steady tap when you click on a button or an app. Right on the spot and with no swiping or sliding afterwards. I can't reproduce this on any of my other devices.
Ergo, it seems that the natural tapping I'm used to isn't working on the x2. It seems like I have to adjust my tap. I think that this could in principle be solved with a setting somewhere, because clearly the x2 is capable of registering this in for example a web page.
The great thing of this is that you can safely tap and swipe in the app drawer to scroll up and down or left and right. The downside is that a tap with a little swipe isn't registered at all. I would say that LG has choosen here for a wrong setting.
My personal experience about screen sensivity.. can you confirm if it's the same for your device?
I noticed a strange touch response.. and after some tests, I can say that the touch screen and icons are influenced by the surface where the phone was put!
with the phone in my hands, it's all ok (only sometimes - rare - I need to tap more than once).
If I put the phone over a glass surface (like a glass table) without touching it with both hands, the touch and the icons not respond!! NEVER!
If I put the phone on my scanner the touch screen works ok, but the icons not (or only few and rare taps was detected).!
If I put the phone over my big Onkyo amplifier.. It works like in my hands.. or better!! even without touching with hands.. only with a finger!
Put it back on my glass table.. and all stop working again. If I put a aluminium foil under the phone (between phone and table).. the touch and the icons works again !!
If I put it on the bed.. it don't work.
LG support say that they have tested the phone about this issue after my report.. but no strange response was detected by them. I don't know if they really tested it..
Try it and let me know what you think about!
tested on glass surface, I can press and swipe through pages with a finger without problem.
it is true that my device is not so responsive, but aint reaching that level yet
i read about a similar behaviour on other devices because some devices need a proper grounding for the capacitive screen to work correctly. You can find this problem via google.
Some devices have problem in a car-mounting, for example.
But i think thats not the problem the thread-opener talked about?
Guys I'm looking to get this phone and after reading Engadgets review of the X2 where they mention that the screen is not as sensitive to the touch as other phones I got a bit worried and started googling which lead me here!
Is this true? The screen isn't very sensitive and you have to apply more pressure than other capacitive phones?
I know that the OP is talking about a different issue but I reckon LG will get that sorted out via software update, or at least hope so!
Please do post your experience about the screen sensitivity of the X2 as this is putting me off. I currently have the Motorola Milestone 2 which is very sensitive to the touch even with a screen protector on it.
Cheers
