(SOLVED) Serious screen problem, please help!

Looks like it was my generic charger causing all the problems all along...
Too high output (6.5VDC where it should be 5VDC)
Ordered a replacement, hoping for the best.
Thanks for all the help!
Sometimes my touchscreen is just perfect. Lately, it's driving me nuts!
When I hold my finger on the screen, the touch screen registers rapid multiple touches. Possibly as many as 10 per second.
This makes dragging and long-press actions almost impossible. Scrolling is very hard and typing is a PitA.
The problem goes away at times but keeps returning. I'm not sure if I had it before the recent update.
At first, it seemed like rebooting helped but today it proved useless.
Anybody, please help!!!!

Do you have a screen protector on the screen? Sometimes the cheaper ones are too thick and the screen doesn't register touch like it should.

Just the one that came on the phone.
Like I said, the phone works beautifully some of the time but registers multiple contacts other times.
I suspect software but it seems I'm the only person with the problem...

do you have a warranty.... sounds like a hardware fault to me.... the only way you can prove it's software (or not).. is to do a factory data reset and then run it with the standard basic build for a few days.. see if you still have problems when you don't have any other apps on the phone.

Do you have wet fingers when you experiment this behaviors?

Happens to me too. I figure its due to gunk on the screen like water, sweat your gf's makeup (a major one)

This happens to me too.
Only started happening since the last update so I just assumed it was a bug in the new firmware. It's like the phone lags and then catches up with itself, very annoying.

I think it is since the update. I'd better reset the phone using SEUS and see what happens.
@ everybody, believe me, I have had the problem through a variety of circumstances and no problem with sweaty fingers etc. It seems pretty random!
I don't have a warranty so re-install here I come!

I would definetly try the factory reset first. I have had similiar issues but its only been while typing quickly. It lags a bit and then it all shows up on the screen plus a few extras of whatever the last character I typed was.
I did read somewhere, can't remember exactly where, that because our screens are capacitive they can malfunction. What I mean is this:
"Surface Capacitive touch panels: a layer that can store an electrical charge is created on the glass panel. When a user touches the monitor with his or her ungloved finger, a portion of the charge is transferred to the grounded user reducing the charge on the capacitive layer. The controller calculates, from the differences in charge at each corner and determines where the touch occurred."
Sooooo if say the ground for the screen is damaged then it will not register your touch appropriately. Hopefully it just requires a reset, cause the latter I think would be a tougher fix.
Let us know

dfan, is it happen only when you charge your phone? What charger are you use? Original?

I did a restore but no change, issue still there, it doesn't happen often though.
Dose seem like a bug and it never happened to me before the last update.
Also it happens to me when not charging.

very bad.. you cannot drink a cold coke and use the phone. I think that it is a hardware related problem. I was trying to reproduce the same with N1 and Legend (with my fingers flooded) without problems. So.. guys with hyperdrosis keep away from this phone!

No it's not a hardware problem as it only started happening with the last update.
Remember the x10 uses different software to nexus one or desire so can't compare with them.
I believe it's the software lagging, this update is faster overall but just lags occasionally, maybe the next software update will fix it, and if not the 2.1 update should definitely fix the issue.

Are you pretty sure?

Tested... it is present on old roms

Well the old roms were laggy as hell anyway. It seems like classic software lag so I still think it's software.
Maybe when 2.1 is released we will find out, or even better when we get stock android running though root, that would clear it up once and for all.
My iPhone 3g also suffered from similar lag issues.

Hells yeah I don't want a defective screen or this thing is done!
regarding your first comment, this is not lag. It is like I had a turbo button. If I touch for more than 1/15 sec, I get 2, 3 or 4 letters.
instead of one long press, the screen continually registers new presses, no matter how firm my touch is.
Imagine how much fun it is drawing the unlock pattern when my phone's in a bad mood...

That dose sound different to the small lag I occasionally experience, very odd.

I've reinstalled the FW and it didn't fix it.
The other day I had 5 straight hours of rapid-fire screen during which I couldn't even unlock the phone.
Gonna have to send it in for repair. Anybody know how expensive S-E are for repairs? Is it even worth doing?

I have narrowed the suspects down to my generic charger.
The charger I bought outputs over 5V (claims 6.5V) which seems to be the problem since I don't experience the issue when charging from a USB port.
New charger ordered, fingers crossed.
Thanks for all the suggestions!

Touch screen w/o touching?

I've noticed that on my NS, I don't have to actually touch the screen to tap keys. I can keep my finger slightly hovering over the glass and it still recognizes my input. Sometimes it actually causes me to mistype at a higher rate than other phones.
Are you guys seeing this too?
Sent from my Nexus S using XDA App

Glad to see I'm not the only one who's experienced this....I thought I was going crazy. It's sporadic at best, but when it happens it is annoying. I can't say for sure what causes it, but I'd love to hear other people's opinions.

I've been getting this as well.

same here. Guess they have the capacitance set a bit too high.....

yup, me too. infact. my home button gets phatom long pressed and the light is off on it...have to power it off/ turn the screen off and on muliple times. that insanity has occured about 4 times thought.

Thanks for the replies. I went back into Best Buy and tried their demo phone. So either it's supposed to be this way or they messed up a whole batch of phones. I wish I could remember whether the vibrant did this or not, but it's not standing out.

Sometimes touchscreen nonresponsive too. This is not relating to partial outer border touching either.

I believe Engadget did mention did this during their review @ http://www.engadget.com/2010/12/10/nexus-s-review/.
Their exact quote: "One other thing of note -- we noticed a few missed or latent presses on the touchscreen which occasionally led to stuttery behavior or an opened item that we didn't mean to tap. It's hard to say if this was a software or hardware issue (and we know that sometimes Android devices can be particularly finicky when syncing). It wasn't a deal-breaker by any means, but we saw the issue rear its head a handful of times, and felt it was worth mentioning."

it's nothing ,, the Samsung galaxy S does that too D:

that happens due to the static on your finger.

Hi
I opened a thread (http://forum.xda-developers.com/showthread.php?t=879872) because I definitely have a problem on the back capacitive button, just wondering how many people are affected?
In fact I have seen this in four devices now, it looks that there is a batch of defective Nexus S phones out there affected by this problem?

It's normal. My Nexus One is like that too. It's magic.

So, it is normal to have un-responsive back button after some times?
Damn ... this is bad. I hope I can cope with it. I really hate hardware problem.
And still could not understand why Google cannot fix it.
Last time from HTC ...
And now from Samsung ...

There's a thread for the back button, that's a real issue. Some people have the Back button issue, some the Home button issue. Both of those buttons are on the outer edge of the phone, so something may be messed up when the phone was being assembled.

Touch screen occasionally messed up

Hi,
I've got some weird problems with my N1. I searched around but couldn't find the solution.
I've tried CM7 stable 7.0.3 and Nighties 87 builds, and this problem happens to both.
1. When I'm running an app, such as "plants vs zombies", or typing with keyboard, when I touch a spot, it thinks I touch another spot. For example, when I touch key "D", it may give me a "space". When I try to place a plant on the left side, it puts it on the right side.
2. When I'm watching videos with MoboPlayer, the screen is locked sometimes (maybe this is a setting that I don't know, how do I turn this feature off?). When I press the "menu" button, it was supposed to unlock the screen, but it actually unlocks and locks back and forth continuely, and the phone keeps vibrating.
All the problems will be gone if I just lock the phone and unlock again. However, it will come back after a while.
Please help and thank you very much!
Andy

Yep, always been a problem with the Nexus One and often on capacitive touchscreens when plugged into a charger. You've stated the known workaround.

I see. Thanks.

Just turn off the screen then back on, it clears this bug and only takes a second.
All nexus ones have this issue.

I traveled from Singapore to the States for about 2 weeks in May and I suddenly had this issue too. I never had it for the 16 months I owned it back here in Singapore. And when I got back after my 2 weeks trip, the problem never occurred at all again.
I'm guessing that it has to do with either the temperature or humidity levels.

I agree with you. I think it has to do with humidity specifically because it happens only when I just left from the bathroom (taking a shower) and there is a vapor, then the touch gets crazy!

Iv'e only had it a few times in about 16 months. But, it's very dry here in Vegas wih very low humidity!

I've had this issue from day one with the nexus one. For me atleast it triggers everytime I have the phone plugged in and I'm using the phone at a 90 degree angle, like sideways in bed, very strange.

This happens on mine too, but if the problem is the humidity, so why lock the screen and unlock it solves?

I have similar problems as mentioned irregularly, but sometimes switching the screen off and on doesn't fix it at all. It's not very humid where I live (except when it's raining). Has anyone else considered replacing the digitizer (the touchscreen panel) of the phone, and if this would fix the problem?

I sent my N1 back to HTC for warranty repair because of this issue. They did something and sent it back saying all good now. The issue occurs less frequently now but it is there.
I suspect there is something in the trackball area that generates EMF of certain qualities (frequency?) and it interferes with the screen circuitry due to poor shielding and close proximiy.
Sent from my Nexus One using XDA App

this is definitely a design flaw of N1, the touchscreen controller chip just SUCKS

Screen responsiveness

I've noticed that the screen responsiveness varies. Sometimes it takes a few touches before it responds other times it responds as expected.
Assume it's user error so are there any tricks/hints when using the N7? Not using a screen protector

+1 on this question.
Not sure if the varying screen response it me (user error) or the N7 itself.
Is anyone else having this problem? Or, as the OP asked, do you have any tricks/hints to share?

It looks like this happens to a bunch of people. It happens to me frequently and I usually just lock the device, pick it up and then unlock it being careful I don't have any fingers on the screen before I hit the button.
I'm not sure if it's a defect or not. Some say it is. I would tend to think so too.

There's another thread on this topic, there I asked this same question.
Do you have a screen protector installed?
If not perhaps you're in a region/area with high electrostatic or humidity, moisture..
Sent from my Nexus 7 using xda app-developers app

No offense, but I doubt the electrostatic or humid environment idea since it seems to be solved instantly by turning the screen off and back on.
I have this problem with a screen protector installed. I may remove it and try without it, but I've never had issues with XO Skins before and don't really want to trash a $20 screen protector.

I've notices laggy screen response on my 1 day old N7. I'm contemplating doing a factory restore/wipe.

I don't have a screen protector but it definitely lacks touch responsiveness.
Sent from my Nexus 7 using xda app-developers app

I have had to on occasion press twice on buttons when the first press doesn't register as well. I've seen that other thread about playing games heating up the tegra chipset affecting screen responsiveness severely, but in my case this is from light usage.

Mine has been pretty responsive so far without any issue. Just got it yesterday.

I've started to notice this issue today for sure. I thought it was my imagination before as I had only gotten it in games but today I got it in tapatalk as well. Thinking about trying for a replacement. I had gotten mine at Walmart so I guess I could go through them for exchange...

I got my 1st one at Wal-Mart too, so I went back there yesterday to get a 2nd one to compare.
It seems to me that I'm not experiencing the lag as often on the 2nd one (I don't play any potentially resource-draining games, so I notice the lag more when I'm reading something and trying to scroll up or down).
I have started to wonder though if, in my case, maybe it's happening because I haven't installed a screen protector yet. I have one on my KFire and don't have the lag/sensitivity problem. So I figure I'll get one installed on my N7 soon and hopefully that'll cure this for me...

I noticed this the last 2-3 days. However, it seems to be only in Chrome browser. I never close my browser, and towards the end of the day, I'll unlock the tab, go into chrome, and I'll have to hit everything twice...keyboard included. I just completely close it out and start it back up, and it's fine again for another day. So it's not a problem for me.

Just had it again and while it was happening I went ahead and enabled the Dev option to show presses and it definitely requires a harder press to respond over time. I believe the digitizer is at fault on this.

ERRATIC nexus 4 tocuhscreen. Ghost touches

so my screen started with this crazy thing. theres a dead line on top of the screen. and touchscreen litteraly goes crazy. opens and closes apps, zooms in and out, swipes. this stops when i turn the screen of and back on, temporarely.
the phone has never been dropped or damaged in any way. just started randomly. i've tried 4.4.2, 4.2.2, custom roms, franco kernel,
flashing stock rom via fastboot fixes it,.
dead line desapears, everything goes back to normal. but when i leave it over night charging. the problem revives. i've seen this problem in youtube and google forum.. with the same deadline on the upper screen..
I Made a touchscreen text and everythiing is fine. but when the deadline appears fails
HELP!

My gf is having the exact same problem with her phone at the moment. I'm guessing that the digitizer needs to be replaced...but any other thoughts are certainly welcome.

I also disconnected battery.. no fix. right now theres no deadline. i think it could be the battery. like when you plug in with wrong charger and phone goes crazy.
right now theres no deadline. works perfectly no deadline. low battery tho:crying::crying:

Could be a grounding issue. When I use chargers that aren't probably made I'll have that problem. Try using another wall charger and another wall socket.

Well, mine it's definitely the screen. I enabled screen touches in developer options and there is a dead rectangular area across the top of the screen that doesn't register most touches...and occasionally sporadic ghost touches start erratically pressing this area not allowing me to touch elsewhere. I'll likely have to start looking at repair options.

happened to me with my previous phone lg optimus black and kind of happened with my nexus. in the previous phone i had a lot of ghost touch. they started happening one every phew days and after six month i had ghost touches every single day rendering the phone almost unusable. got it for guarantee and they changed the touch screen. the problem started again on the new digitizer with some sporadic ghost touches, on the same day! after that i bought nexus. after a while i saw ghost touches too but it's rare. for me the ghost touches happened when i was playing a game called tubing and with time happened every where. tubing is a game where a lot of quick touches is required. now that i stopped playing that game everything seems fine
a friend of mine had this problem some time ago with htc hd2. the service told him that this kind of touch technology has problems in warm weather(i live in cyprus and in the summer it gets up to 42 43 degree celcious) .

I have this same issue, was wondering if anyone found a fix yet?

I have lost all touch sensitivity in the down part basically I can't use the Nav bars and also above the nav bars sometimes its very hard to press on things check out my video I have it here in the last part http://www.youtube.com/watch?v=eDDOSyLLnGs&feature=gp-n-y

nexus 4 ghost touches and dead screen.
Believe it out not, the crazy ghost touch and dead screen areas are NOT the screen. It is the battery. It sounds crazy, but it is true. The bad party is, nexus 4 batteries are old. Buying a new one won't necessarily solve the problem. I would buy the brand name this party battery.I have had bad new oem batteries die to their age.

Hello guys ley me join this party of ghost
As my device is also doing same weird thing like unnecessary touch without my feedback in most of third party app, setting app and in play store it goes crazy and start clicking on any option available without my touch
But the thing which is making me frustrate that this happens only on custom kernel as I tried all with stock google factory image 5.1 and this problem arise just a few days back and I was on custom ROM with custom kernel before 5.1 update everything was fine but after 5.1 update I mean custom 5.1 ROM with custom kernel this problem arises now if I m going back to 5.0.2 custom ROM with custom kernel my device become crazy and just start clicking any option in setting app I m totally stuck with Google factory image and stock kernel
Please guys if any one has pepper solution for this ghostly touch help me so that I can enjoy custom ROM and kernel :crying:

Mouse BlueTooth (without adapter)
I found the cheapest possible solution, as the replacement digitizer is not profitable.
I bought a mouse BlueTooth (without adapter) without problems and now I can move the cursor around the screen over the entire surface.

In my case, I bought a mouse i-Tec Bluetouch 243.
