screen calibration - Nexus One General

is there a way to calibrate the screen? sometimes feel the click is not accurate.

no, these screens should not need calibration anyway. If you're talking about the click being off a little on the home screen I have that as well, but it seems to be limited to the Live Wallpapers. If its off by alot you should send it back for replacement.

when i click the dot, sometime the search box pop up. the dot is above the search botton

dot? what dot?

I think he means the dots at the bottom of the screen to move from one screen to another on the Home launcher. The dot(s) is/are right above the search button on the bottom right of the screen.

oh, yeah that does not sound normal. try restarting and if the issue persists you mgiht want to consider sending it in.

I've noticed sometimes random touch events happen, I'll touch something, and something else gets activated more than half the screen away.

are you sure you aren't touching another part of the screen?
Sometimes the palm of my hand touches the bottom left of the screen and that will cause random touch events.

You need to touch slightly above the dot. Otherwise your finger is very close to the google search soft key.

I know for fact that sometimes I DO touch other parts of the screen like with my palm, etc by accident. however there have been cases where this wasn't happening and I still have miss touch events.
Example. I was holding my phone with my fingers in landscape with my left hand, and using only the pointer finger of my right hand to touch something in the middle top of the screen, at which point the phone pulse vibrated and the quick search screen popped up.
I posted to the google link outlining the different events that I have noticed. Multitouch would fix point averaging between somewhere you're accidentally touching and where you intended to touch. This however isn't the only thing going on, as I do believe there is some random strangeness occurring. I never had any such issues with my G1.

it happens to me,too, i thought it is caused by my palm touched the edge of the screen when i clicked using finger, but it is not. when i restart the phone, it,s gone.

yes. that's the dot.
I read from another reviewer, he said the sensor of the soft key is located a little above the icon for the key. this may cause the problem.

This messes up pretty much everyone I hand my phone to look at/play with. Its fine if you're aware, but it does show a sign of less refinement in a device that would have been nearly 100% free of hardware design flaws.

I feel the same way, especially with the soft-buttons and the "p" key in portrait mode. Last night after walking a bit outside my key-presses were atleast an inch off.....I attributed that to my fingers being a little staticky.
Othertimes my fingers just never work on the screen for a few seconds, rubbing my fingers together fixes this problem.
Something to do with http://en.wikipedia.org/wiki/Capacitive_sensing I guess

I find that sometimes my fingers wrap around the phone and just touch the front edge of the screen while holding it, causing random key presses. I guess I'm still used to holding the wider and less sensitive Touch HD.

Screen Alignment

Is it just me or does the screen alignment seem to be off a bit and you have to put a lot more pressure than you have to with the Wing ...............
My screen alignment is fine but what I notice is that in order to get a better response from the screen is to tap it with the middle of your finger instead of the tip. I no longer have to press hard as long as I do it with my finger print, middle part, of my finger.

Are you talking about opening up the keyboard (moving the screen?) Cause, yes, my wing was looser, but it wobbled from time to time.
If you mean touching the screen, the wing was definitely a harder press.
I noticed the alignment is off once in awhile. I press a link on a page and if its a list of links, a lot of times it will press the one above where i am hitting.
As for pressing harder then the Wing, when i try that it will scroll the screen instead of pressing what i wanted. But it depends on what Wing we are talking about too. My first Wing that i bought last year was more sensitive then the exchange Wing i got last month. So it could depend on the device that you have.
Because it's a capacitive screen, pressure shouldn't matter to it, just touching your finger should be enough. I think it's where it averages the center of your finger out to be. Some apps like Street View have a thing where if you touch and hold, you can drag a target around to help be more accurate, I think you can touch and hold on a link to see if it's the right one before you release and click it.
Yep it is off....but that's how it has 2 be cuz we have no stylus....some ppl have boney fingers...some ppl have huge mcdonald n burger king kinda fingers...lol. see this way u can press a spot n it'll get the link, or press more accurately without a stylus....a stylus is easier, but they wanted this 2 b on iphone level....so they stayed away from the stylus....wat I do is click my finger above where I want to press...like just over it...not directly on it...like the list thing mentioned above, I too used 2 click on the wrong thing...or use the trackball 2 highlight it, n click wit trackball....or zoom into the page and then click...I have multi touch so its easy...

Am i the only one with this touch screen problem ?

Sometimes the touch screen is WAY off and only restart is fixing it. Noticed this 2 times already.....
I've noticed this too. I was using the browser, and my screen presses were registering as all sorts of random things (like pressing the middle of the screen would press the zoom button). Restarting the browser seemed to fix it.
Add it to the nexus one issue list.

that's from a lack of multitouch. your hand is probably just barely touching the lower corner of the glass. when you press again in the middle, it registers on the softkeys. it is one of the things I *HATE* about this phone. I always seem to be touching the screen on the very edge. you almost cant use it with just one hand.
I find that I do that with my HTC Magic sometimes as well, the 'webbing' between my thumb and index finger sometimes touches the corner of the screen and brings up the 'app menu' in my left hand, or the 'add widget' menu in my right hand (sense ui). Just another general thing about touch screens and their placement
the four touch buttons arent that accurate. didnt have this problem on the droid. i rarely miss it there but on the nexus is becoming 50/50 chance of it not registering.
Lol how are you guys holding the phone, i always use it one handed and havent expirienced this, i guess everyones different.

This not necessarily a problem with this phone in particular. It is a phenonema that happens on all capacitive touch screens (that do not have multitouch). I work with them all the time (much larger scale) and the slightest touch on a border results in what appear to be calibration issues.
Multi touch takes into account for this, non multitouch does not.
This has happened to me also. Same exact thing, in the browser, the touch was way off, really way off. I was pressing the middle and the zoom button pressed. It was on the table so I know my other hand didn't touch it. It was also vibrating sometimes when I pressed the middle of it. Restarting seems to have fixed it for now.
happened to me in SMS and browser and the only fix was restart the phone.....so its not me accidentally touching the screen in another point.
ps. its so bad that i couldnt even use touch screen to power off the phone. i had to use track ball. (now i know why its there )
I've had this problem as well as other with touch screen. Sometimes I will hit an icon on the main screen and it will jump screens. When I'm in the menu's i hit one of the options and it goes to the one underneath it. I'm CLEARLY hitting the option I want and not the one below so it is infact a hardware problem in my case. I will be in the browser and hit a button and it will exit out of the browser, very annoying! Mine is unlocked but I wrote HTC so lets see what they say.
its a known prob with this phone, ppl are complaining all over Google forum, its very annoying, when it happens it doesn't just happen in the browser, also in text message n home screen ect...

Webbed fingers are gross.
I have now experienced this definitively once. It happened while using the dolphin browser. I wiped the screen off, set it on a table, poked with only one finger, and could not for the life of me get the software keyboard to click on the correct button. Just wouldn't happen. Had to restart the phone to fix it. But it's only happened once since I got the thing on launch day.
^ same thing for me. Does the OTA fix this, I have not received it yet. Wish I saw this before I created a thread, sorry.

i dunno, but touches (especially multitouch) seems ALOT more responsive and accurate than before i did the new update... i used dolphin prior and pinch zooming seemed jittery and like the phone didnt want me to do it... now everything seems smooth as butter!
obviously this is only short term though, but hopefully this fix will also address some of the calibration issues (that i also experienced) that the N1 has been known to have...

touch screen issues

Anyone else having their touch screen stop working property until they have to reboot? It's like it gets way off on where I'm actually clicking.
I have experienced that, but only after I had flashed the modaco rom. I basically returned to stock firmware this morning and am having to re-root my phone...
I have had a couple of occasions where it doesnt seem to respond correctly.
For me its like it looses the calibration, seemed to noticed it when the device is tilted horizontally.
reboot sorts it, only happened once or twice though.
If the phone is in your hand, make sure your other fingers aren't curling over the screen around the edges to much.
I noticed this happening, and backed my fingers off around the edge of the screen and it started working fine immediately.
I think the screen is just extra sensitive.
Curious if that helps.

I read somewhere (maybe on this forum even) that non-multi-touch systems have this problem. Have the same issue with my HTC Magic, but after a while you learn of a way to use the device single-handed while not touching the screen.
I dont know if this helps or not but I have no idea what you guys are talking about

The calibration problem (the screen registers a wrong spot than where you touched) comes up if you try to use a non-multi-touch phone single-handedly, so part of your palm (between the thumb and index fingers) touches the edge of the touch screen. Especially if you are trying to reach a top area of the screen while holding the phone with just that hand, likely some part of the palm touches the bottom of the screen.
If you want to try having the problem, you can touch the edge of the screen with a finger and try to click a link with another. It won't register the right spot.
Supposedly the problem should go away as soon as you lift that body part up from the screen.... so I don't know if this helps the OP or not.
same issue
http://forum.xda-developers.com/showthread.php?t=615711
does not look like its happening all the time. Ran few tests and still can't duplicate the problem in order to find the cause. so far this happened about 3-4 times on my phone.
i hope this gets resolved soon and that its not the touchscreen issue.

I've had this exact thing happen to me a few times. I notice the tip of a finger on the edge of the screen, move it, then it works fine right after. Sometimes happens with the base of my thumb hitting the bottom left corner too.
Just make sure you're not accidentally touching any of the touch area and it'll work fine.

I have had this same issue on my G1 as well a N1. This problem only happens from time to time, as happes with stock ROMs and custom ROMs.
For the N1, I was initial pulling the battery; however, I have found that if I hold the power button down (don't let go) and then touch the screen to unlock or power if off.
I have a friend with the Eris who was having the same problem; Verizon released a patch earlier in the week that seems to have solved the problem for him.

You can perform a soft reset on the Nexus One by holding volume down, the trackball, and pressing the Power button on top. A half second later, your phone will reboot.
I am also having these touch screen problems, and I can confirm I am not touching any other part of the screen to have it interfere with the non-touch-screen interface. I been testing with what people has been saying on here with having any other part of the screen being pressed, so I have been testing it out and I can say its a different response then what I'm experiencing.
Here is what is going on with my nexus one:
1) it happens at random times (my device is on my table and I am pressing buttons with one finger)
2) it only affects the bottom-left portion of the screen when it happens, touching everywhere else is fine
3) it thinks I'm pressing an area around the soft keys, an example is if I press 'A' it thinks I press either the '?123' or the 'back' button, same if I press 'd' it thinks I'm pressing the 'menu' button.
I can conclude that since not all nexus one owners has this problem it is a device issue, which what is going on is probably the same as if someone was accidentally pressing a part of the screen, but it could be part of the device is assembled incorrect or deformed. The physical form of my phone is off on the right side, I can feel the gray plastic part next to the black border next to the right of the screen is a little more raised then the left side.
But there is my experience with whats going on to me and my two cents.
Ive had this a little bit on my device as well, but I think it's a software issue since it went away when I pressed the home button.
edit:
Also it has happened exclusively in Dolphin browser
here too
Sporadically, it happens with my N1 as well. When pointing at the middle of the screen (in a list for example), the input registers 2 cm below my fingertip. Rebooting fixes this temporarily but it is annoying.
A SW update could perhaps cure this behaviour?

I just had this happen for the first time, all my presses were registering way below where i was touching, tilting into landscape in an app then back to portrait fixed it for me.
So now it happened to me too. I have the Nexus One for almost two weeks and I never had the unresponsive touchscreen. Of course I noticed that the center of the softbuttons is shifted upwards and that they don't register very well in the middle where they should and I had the problem before that the sms text input box didin't registered in the center so that the keyboard wasn't popping out but that is all only a problem of adjustment. Today in the morning after my phone was on standby over night I put in the charger to charge it and I got an email with pictures. I scrolled through the email and all of a sudden the screen became totally unresponsive. I tried to scroll and the screen registered at a complete different place. All of a sudden the email was gone because the phone registered the delete button even though I never pressed it. I could close the gmail program but I had a hard time to scroll between the home screens and the live wallpaper became unresponsive too. I decided to do a restart but I had a hard time to press the shutting down button because it was unresponsive too. This all happened not after heavily usage of the phone but after maybe 1 minute usage.
I am sure that I didn't touch another part of the screen when this occured because I realized before already that the screen becomes wacky if you touch it at two different places (lack of multitouch, so stupid to disable it). I hope that this is a software issue too. I can live at the moment with the 3G problem because it doesn't stop me from using the phone. The unresponsive touchscreen scares me more because because it becomes completely unusable.
i've noticed this with low battery. Twice its happened to me, the first time was when i first recieved the handset. and secondly was this morning when my phone was off with no battery again.
anybody want to leave their battery to empty out and try test if this is correct?
I've had this happen a few times in the ten days i've had the phone. I always make sure I'm not double dipping on the screen, and its easy to do since it will exhibit this behavior for a few minutes.
In my experience battery level has no effect on it.
A reboot always fixes the issue.
I figure it's software based.

[Q] G2 "ghost clicks" screen sensitivity

Has anyone noticed that their screen is picking up "clicks" without actually touching the screen?
on occassion my screen will detect a button click even if i haven't actually touched the screen. It's starting to get annoying, but I don't know if that's just the way the phone is, or if i'm too used to a capacitive screen rather than a heat sensitive one.
i had this happen a few times. not enough to bother me that much. it happens sometimes when my finger is hovering really close to the screen, like i'm getting ready to press on it but not yet because i'm still reading whatever it is on the screen, and then it ends up clicking it anyway. i think its happened a total of 3 times for me. 2 other times though, i've had the screen do double taps when i was just swiping around. trying to scroll up and down on a webpage and it registered as zooming in. i did do some zooming in and out a few seconds prior so i think for some reason it was "stuck" on double tap mode or something. had to switch the screen off and on to fix it.

yea it does the same thing for me as well. I sometimes go to press a letter and the letter gets pressed twice. it's really annoying. i'm hoping that if i buy a screen protector it will get better but i'm betting that I'm gonna have to battle with LG's terrible customer service.
Never happened to me. The screen (as with every other smartphone I have had) doesn't react unless I'm actually clicking. Even if I touch the screen with the SLIGHTEST touch I can do, it doesn't react. Which is good, no problem reacting when I actually click.
I guess it might have something to do with my fingers being hard as metal due to guitar playing or something.
On mine it seems to get worse as the screen gets oily. If it starts to wig out, I wipe down the screen and that usually solves the problem for a couple days.
When my screen gets overly sensitive i turn the screen on and off again. Usually fixes it.

Maybe i'm just crazy, but when i spend this much on a phone I shouldn't have to turn the screen on and off constantly to get it to work.
Hopefully LG realizes this is a problem and rushes out an update...

it happened to me... not only that the screen freezzes from the ghost clicks... the clicks are on middle of the screen staying... for example by playing Plants vs Zombies 2... the screen doesn't react at all.
I think that has something to do with the "smart-stay" or with the screen time-limit.
... plus of that... the phone gets really hot at that time.
any solutions?... or back to guarantee?

Never happened to me, however I know exactly what you're talking about from using cheap Chinese tablets. Therefore I suggest getting it fixed or exchanged.

[Q] Phantom touches screen issue

So I've been getting ghost or phantom touches on my phone for the past few weeks. I couldn't figure out what was causing it because I've never dropped my phone and it never got wet. The phantom touches only appears down the right side of the screen in almost a straight line. It doesn't happen all the time and I thought it was random but I got it to occur at a successful rate. If I press down on the top left corner of the screen, it would cause the phantom touches. When I press and hold down the top left corner of the phone, everything is fine and no phantom touches appear. I decided to tighten the screws on the top left and it seems to have made it a little better. I'd have to really tap on the top left of the screen to make the phantom touches appear again and it doesn't occur at a 100% rate but it's still occurs.
Anyone know what is causing this? I thought it would be a broken digitizer but it doesn't make sense that tightening the screws would cause the issue to almost fix itself. Problem with the geomangnet? I'm not sure what that does really.

Move the fingers slightly about, trying to have both (all) in a straight horizontal line.
After only a bit of trying one (or more) detected fingers should disappear (become undetected) or ghost touch detections should appear.

Thank you for the help and suggestion but I've already tried this. My touch screen is fine in terms of detection. I can put 10 fingers on the screen and it would recognize all 10 fingers. My issue has something to do with the top left corner of the screen affecting the right side of the screen. Like something is loose. When I clamp down on the left corner of the phone, everything works fine. No ghost touches (that sounds dirty) or any of the sort. When I let go of the top left corner, I will some times get ghost touches.

It's not a firmware issue. It's definitely a hardware issue since it starts tapping on buttons inside TWRP recovery. Ah well, I tighten the screws even more and it looks like the phantom touches are gone. Hopefully it stays that way even though I destroyed a screw in the process. Those tiny things are fragile.
if the touch ghost click is in some certain location most because of pollution (mainly chemical), best is use ISO alcohol also use a very tinny sharp blade, like a very thin one and slightly go along side the place that does this, sometimes you have to try both horizontal and vertical, then clean with ISO, do a few times it does alright. it does work on most of touch screen include note 3 as well. I've been in IT and fixing all electronic for last 30 years in New Zealand. if you had problem text me on 021 548484
