Screen responding without touching it - Galaxy S III General (US Carriers)

Does anyone else have their screen respond without touching it?
I've noticed this in go sms. On the conversation list, the last one on the screen is sometimes pressed without me touching it. I will press back and it just goes back into it.
I recently noticed in web browsing too where the screen would refresh on its own. I clued in that the refresh button is on the bottom of the screen.
Seems like the bottom maybe 2 cm of the screen sometimes responds on its own.
Is there any app that I can see where the screen is being pressed?

Settings, Developer options, Show Touches
That will visually show you where any screen touches are occurring. The screen is a bit sensitive for me sometimes, but I haven't seen anything crazy yet.

I wish you could extend the amount of times those dots stay on the screen for.

Yeah it's unfortunately a little basic. Maybe something on the play store that could do the same thing but also have some customization?

I have enabled it in the mean time anyway.
Is anyone else experiencing this?

Same here. Sometimes it happens to me. I would say one of 50 touches it'll react even without me pressing finger on a scren.

I definitely know what you're referring to, and it does seem to happen only on the bottom of the screen. Sometimes I'll trigger the screen if my finger is close but not touching it.

The thing that bothered me today is that i was trying to press a button in the top left corner and the bottom link kept being pressed so I have to hit back and I was trying to beat the bottom press but I couldnt lol
I dont think there was any moisture on that part of the screen either

Yep, but not on this phone yet...
I say not yet because it's happened to me on almost every one of my touch screen phones. It seems to happen to me when the air is dry and I bet it has to do with there being more static electricity around. On those days when you're shocking everything you touch, those are the days when my phones seem to act up. It happened on my G1, my vibrant, Droid1, Droidx, and two of my bionics. All of the problems went away although on my 1st bionic it was really bad and almost completely unusable. The next day it was back to normal. Maybe it's just gremlins.

answer:
it happens if/when you use a DIFFERENT charger for the phone. you should be using the charger that comes with the phone. If you use a different charger (from a G1 or from a razr or something), then the screen tends to mess up, even when off the charger.

Please explain what this has to do with the charger

So just had this happed today with the "show touches" on and I did not see any touches.
I am wondering if this is a manufacturer defect now

Mine does that also, specially when I'm in the car sometimes it just randomly unlocks and I go wtf!

Is yours also happening towards the bottom of the screen?

For those of you with this problem, try pulling the battery out for a minute or two and also try touching something metal if you can. You know to discharge any static built up. (Worth a shot right) When I had this problem on my Sensation everyone was reporting that it was the charger they were using. I don't know if that was correct because the problem went away even though I was still using two different chargers. One charger was for the GNEX (same as GS3) and the other was the HTC charger. I really think it has to do with static electricity build up. If you think about the way these digitizers work it really makes sense. It seems to happen to me during spring time when it's dry and windy.

That is a good theory, but why would the static shock only be hitting the bottom part of the screen?

i don't know why. but i'm sure it's the charger. this happened back in the G1 days when android first came out. i did so many "experiments" with different chargers to figure out what was causing the screen to be all glitched like this. found out it was the charger. same thing happened with my vibrant, and same thing happened with my sisters sgs2.

Touchpad randomly activates

Has anyone else experienced their cursor randomly moving around while trying to type or pages scrolling while they're trying to read? My G2 has been doing this fairly frequently and I can send it back but I'm somewhat afraid to since mine does not have the hinge issue and (so far) has pretty damn good battery life. I don't want to just swap one problem for two more
It happened to me once, but I have yet to see it happen again. Strange though.

Mine is rediculous. Can hardly type. I also don't have the hinge problem, but the trackpad is all over the place.

You have the Desire Z?
Mine does the same thing with the cursor. Makes it very difficult to type a lot of the time. The only thing I can think of is maybe it's a lighting condition... maybe light reflects on the trackpad a certain way that makes it think your finger has moved over it.
I hope there's a way to fix it!
Im curious, are you folks charging when youre having these issues? i had the problem temporarily when i first got the phone so i unplugged the usb cable and havent had it since.
no mystery here guys. it's changing light conditions that are affecting the optical pad. it's the same notion as an optical mouse, if the light doesn't reflect back right it can go all over the place. try finding someplace with a strong overhead light and angling the g2 back and forth and you'll see it activate the pad. that's how it works, light not touch.
Had the same problem, only when charging tho.

I think you are correct...the desk at work has spot where light can come through...when I have my phone laying flat the screen starts to go crazy!!, I was like wtf. It ONLY does it in this spot,no where else...I guess that explains everything

Yes, I'm definitely having this issue. I started a thread a while ago about it. I took a video of it happening, too.
http://forum.xda-developers.com/showthread.php?t=799435
I have track lighting in my apartment, and that's what I think is triggering it. Mine's not as bad as the rest of yours seem to be. It very rarely "goes all over the place" for me. It just highlights random buttons once in a while. I can see how if it activates during typing that it would be a huge pain in the ass.
Stupid optical trackpad... was was wrong with a track ball? I never had a problem with my G1's trackball. Doesn't HTC test these things?
Yup, that explains it. That was my suspicion. Especially since when using Swype (where my hand covers light going to the trackpad) it never does it. It's never been while charging, though - not specifically, at least.
Try holding it towards a light and wave it around. You'll see the cursor jump around. Makes sense. Kind of annoying, but at least it's not a defect.

I actually had to stop using swype because it would happen EVERY time I tried to write in portrait mode
Strange, but it could just be the difference of how we hold our hands or something to that effect. I think the lighting thing does explain it, though.

That was my thought as well, T-Mobile should include a "how to hold" guide in the box
This happens to me whenever I try to use the phone when I'm sitting on the couch with my back to the window. Only place it happens.
Called T-Mobile a few days ago about this and the hinge issue and they immediately issued me a replacement. Probably won't be any better but worth a try right? And if it keeps giving me problems then I'll keep exchanging it until the Nexus Two comes out lol

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?

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 ...
*Still waiting Nexus S from UK*

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!

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.

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.

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

Poor Capacitive Digitizer

I'm loving my Note, but just found a small issue. It's not enough to return it, but it's there. When, say drawing with your finger, or using Swype, the lines can turn out rather jagged if you move your finger slowly. I've attached a picture showing this. I alternate between drawing slowly and quickly.
I've noticed this on other devices, such as the Nook Color, but wouldn't expect this out of a high-end device. Has anyone else noticed this?

Could the jaggedness be caused by finger shake?
Maybe partially, but here's my test on my phone. Its a Samsung Mesmerize: part of the original Galaxy S series

Also, don't forget that there's the object tool in S-Note. It'll straighten any lines you draw.
I've also noticed that with my finger, it only happens some of the time. This issue also makes scrolling a tiny bit jittery. All is smooth with the pen.
I'm wondering if it's just a slight defect that's specific to my Note...

A couple questions:
Is battery saver on?
Is this only happening when you are plugged in?
If nor, Is this phenomenon happening more pronounced when plugged in?
Is this happening inside the xda app?
Anywhere else?
My xda app on the tablet sucks. Its the one app i have that constantly crashes (other than crackle), randomly.
i haven't witnesssed this phenomenon OUTSIDE of the xda app - i have noticed a weird lagginess, almost as if the text was on a weighted spinning wheel, and when you spin it, it slows down almost as if gravity is pulling it down due to the weight.
some of the GS2's (especially sprint variety) had an issue where if it was plugged in, the touchscreen did not respond very well and TouchWiz went 4x as slow. it sometimes till happens if i use the wrong wall outlet. again, i haven't seen this happened while plugged in (the cord is too short for me) but try doing this without it plugged in.
i haven't had any problems with the Wacom digitalizer. i mean, it's top of the line, right? i haven't really used my finger to draw a straight line (i thought that's why we had a pen) but when i did, i drew it mostly straight until i drew slow. then my own FINGER was moving the line up and down and it became squiqqly. i doubt it has to do with the wacom digitzer, but perhaps you have a bad one. i haven't had the problems you've reported, and i can assure you i have been putting this tablet through the grinder TRYING to find things wrong with it. Blame Asus for what they did to me with the Prime and Infinity but all I can complain about is losing 14 pages of Snotes after the update and the squeekiness on the right side of my tablet. As i'm using this with BT keyboard and BT mouse now with no drop in speed, i'll take the squeekiness anyday.
I'll keep searching for this digitizer issue. originally i had some sort of digitizer issue but i haven't had it since the update. it was suggested to me to do a hard reset but i didn't go that route. i also find this fascinating that it's unlike the old Windows Phone 98/5/5.1/6 editions that had you touch your stylus to a certain part of the screen once hard reset to calibrate the screen.

Power Save mode was off. It becomes more pronounced while plugged in, and sometimes it'll stop tracking my finger while charging. It happens
in most, if not all apps I've used.
In CM10, the problem isn't quite as bad, but that could be due to Project Butter and how smooth everything is. It is still there, however.
I'm really hoping its an isolated issue, because besides this, this tablet is excellent(and this issue doesn't *totally* degrade the experience)

I noticed this thread earlier and was wondering if it was the same issue. As said, I'm really hoping this is an isolated problem. There's a good chance I'll exchange this for the 32gb (Best Buy didn't have it at the time), so I'll post back here if I do. Or maybe its just a driver/kernel issue that can be resolved in an update!

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 only had this issue when i charged the phone with a cheap Chinese charger, it would go crazy till i rebooted, as above grounding issues,
but op said it was gone with stock rom, so its not a hardware issue, tried charging via other means

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.
