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.

Really? Are you saying that these problems happen to all Nexus one and we all have to live with them?
By the way, I have these problems regardless if I'm charing or not.

Correct.

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.

+1, always happens to me!
But never happened in other conditions.

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

Were there any bears around? It could be the bears.

southern china. occurs occasionally also. yet not so often these days. more often when charging. it seems that temperature matters alot, not sure about humidity.

For me, solves only for a short time. If conditions stay the same the touch gets crazy again.

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?

thanks all

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.

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

something wrong with the screen

Got my s2 yesterday and its a great phone
but suddenly the whole screen turns yellow for a second then its back to normal
this happened two times in two days
dont know what to do did anyone had this??
Waiting for your opinions.

Given that it's brand new, I'd return it and ask for an exchange.

Hold on, do you mean that the screen gets discolored/dimmed just before the screen out time? If it is then it's normal, otherwise it's manufacturing defect.

Did it do it before you started loading apps on the phone? It could be an app conflict. You might want to try a hard reset and see if it still happens before you begin loading apps. You're going to have to start over anyway if you exchange it.

Screen flickering problem

Temp fix on post 7
Hey, I've owned my phone for
about 6 months. It has been fine till about a week ago when I flashed a miui rom (Mintberry). At first, it was just occasional flickering, everyday or two for a few seconds, but now it's turned into a fair bit more.
If I don't use my phone heavily for about 3 hours, and go back to the phone, the screen has turned completely grey. When this happens, no matter what state my phone is in the screen flickers. It generally begins flickering very fast then after 5 seconds the screen is completely grey (even once rebooted).
I have dropped my phone a few times like everyone does, nothing severe or even close though. I didn't drop it then have it instantly happen.
I have since tried a few things...
Changed pixel density in rom toolbox (works once rebooted, but only till I stop using)
Changed from miui to ICS (no difference, but took an hour for it to start)
Am I looking at buying a new screen?
Edit: tried another battery, no success (didn't expect much)

I had similar issue with my phone. I do not think it has anything to do with software.. but yours is far worse thn mine.. I only had minor flickering which could only be seen sometimes and you really need to notice it with black or white background.. I tired diffrent roms it was on all of them.. I switched back to original rom.. and then got my screen replaced underwarranty... working fine since then..

OK thanks, ill give them a call today.

Had mine flickering in the same fashion. Out of warranty. Took it to a repair place and apparently it was just the screen connection was loose - thats what they told me anyway - $80 later everything worked again - probably ripped me off but im not a hardware tech so didnt want to screw with it myself

I'll have a look at a disassemble guide today, see if I can fix the cable. Thanks man, generally screen flickering is from a loose cable.

Well today I found a fix...
I accidently left my phone in the car when it was pretty hot. Seemed fine when i used it for a few minutes so i assumed it was water damage and decided to take the battery out and leave it for a while.
Came back to the phone after i had done the shopping to see if it was still working. Nope... It was noticably colder though as the car was now in the shade.
I ended up getting a heat bag and wrapping it around the phone. The screen almost immediately started working and the screen was perfect.

I9500 Screen flickering (Imp.)

Hi guys,
I have a galaxy S4 I9500 version and I have observed a problem with it. I was sharing media with my friend's Xperia Z via NFC, while doing that, my phones' screen started flickering highlighting clock at the top portion.
Later I turned off both mobiles' NFC and taken both mobiles close and guess what my phones' screen flickered again.
I checked it with my old Galaxy S I9000 which doesn't even has NFC, again S4s' screen flickered.
Then I went to service center to show this issue, as they were not having any other S4 there to crosscheck problem, they asked me to visit a Samsung mobile shop. There I checked it with three S4s' which were on display and I found that problem was there with each and every S4.
So guys can you check your phones' for this issue and will it cause any problem to phone as the time passes??

similar type of problem

hii,
i am facing similar type of problem. the diffrence is that i get such flickering whenever i am using the mobile data network after evry few minutes and the flicker is like a flash(means it lasts for a fraction of second). i started to have this issue from past few days and this is extremely annoying.
Dont know wat to do!!

But I think it could turn into an issue because earlier my phones' screen was flickering and waking up automatically highlighting clock just like shown in that video.
I submitted my phone to them and they have replaced display with new one. Now it is not flickering automatically but it does while holding devices side by side as that sensor gets triggered by any magnet. So there is a possibility that the sensor could get permanently affected by a strong magnetic field and triggers the screen to wake up automatically.

They replaced display with new one and now the problem is sorted out.

Yesterday I tried something with my s4..
I disabled samsung link, clock digital(both of em), watch on, and dropbox.
The problem of flickering and clock appearing on top was GONE!! until......
I turned on the data network and found it coming back again...
I figured that it happened to me since i updated it to UBMG1 Indian firmware from BMEA
So i am now rolling back to the latter and sammobile here i come

Even i have also tried a lot of things... but problem was still there.... i think it messes with hardware and there is only one solution and tht is to replace the display with new one... if you find sonething to sortout this issue without replacing any hardware part...pls post it here....

Does any one got this solved.. as said by one member, even in chennai - tamilnadu, they are not clear on what the issue i am explaining to them, they just changed the motherboard. but no use still.
"S-view mode activates itself, dono why... it happened for me in a month old S4, i got my motherboard replaced, but still the issue is persisting. but the frequency became less. thats it. other than that no use.
as mentioned by one of the member, it is annoying as it happens any time u work with your phone. in any screen suddenly "

I got my screen replaced but in vain.. I think using the S view cover will help because the flickering is caused by s view initiation (black screen with clock) which is initiated by a magnetic sensor..
Buy unfortunately the s- view cover is costly and so I cannot buy it at the moment .
A possible solution is to turn the s-view service off to stop the flickering issue..
If any developer on the site could help us out..

- Actually am using the S-View Cover. But with no use, when its out of S-View cover it behaves erratic by switching to S-View display automatically.
-Yes you are right it can be a software problem ,but take my words, i used a S4 which i bought on launch date in India, i used it for 3 months, then i gave it to my cousin, and bought another new one - this is the one which is showing up this S-View Issue,
the old one which i had was a GEM, not even once i had this problem of S-View with it, both where of same SW revision level, hence there is something to do with the hardware.
am just waiting for the October 4.3 update, if this is not solved in that SW by any means, then am gonna **** on every Samsung technician in the service center, they don't even know the difference between Hall sensor and proximity sensor!!!! , for making them understand the problem in our phone itself is painstaking..
in between is there any change to bring this issue to Samsung's eye.!?

True the service center's technicians
Don't know anything...
If you report that the s-view cover also gives the same result instead showing the s- view when it is supposed then I won't buy it because I only wanted to buy it currently just to fix the issue..
Also just waiting for the android 4.3 update..

That's not a issue. It's s-view feature in phone. If your phone get close to any magnet/magnetic source then it will activate s-view screen.
A lot of devices like iPad and Nexus 7 have a small magnet in them to provide support for cover/accessories. If your S4 get close enough to that magnet on other device it will activate s-view screen.
I dont know exactly if your other phone that you are trying NFC with, has a magnet. but there should be.

I know that it is a feature but it comes just in between typing process or running through the temple (temple run) and it disturbs a lot so I thought of using the s- view cover so it will restrict the feature to only when needed out initiated by closing the cover instead of coming every time in between activity..

i have again given the phone to the service center, lets see what happens next.

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) .

THIS seems to be a grounding issue. after charging it comes back. but after a while without charging comes back.. no fix yet! i hate how google doesnt give support about this. theres a ton of people with this issue

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.
N4 is not for me everyday device.
In my case, I bought a mouse i-Tec Bluetouch 243.
