Why doesn't google respond to this http://www.google.com/support/forum/p/android/thread?tid=04134c63c784258e&hl=en
A ton of people are complaining and I really can't see why this could be a hardware problem when it goes away after you lock and unlock the phone. This happens a lot to me and is super annoying. Here is a video of it:
http://www.youtube.com/watch?v=4DmVV_B-SE8
What do you think can we pinpoint this?
I really think this issue has to do with accelerometer. When your screen goes crazzy try using it in other position, the behavior changes a little until it dissapear without turning off the screen.
im having similar issues, when i tap, say, in the middle of the screen it registers as a tap on the bottom, this is only occasional, and rebooting seems to temprerarily(sp?) fix this issue, however it is quite annoying, and in op's link there are a bunch of other users having the same problem. now, what happens to us that have unlocked the bootloader if this is NOT a software issue. i have only had my nexus for a week and i would be quite depressed if this is a hardware issue and it cannot be fixed/replaced because of a manufacturer defect.
I know that this has been a fairly common complaint about the Nexus One but i'm wondering, roughly what percentage of people actually have this issue? To clarify, i mean the problem whereby touching the screen in one place is actually registering elsewhere on the screen.
I've had this problem since buying my n1 and having to constantly turn the screen off and back on again was driving me nuts. Finally i sent the unit back to Vodafone for repair and they in turn sent it to HTC to be fixed. So yesterday i got it back with an enclosed statement along the lines of "we have fixed your fault etc..".
Three minutes into using the damn thing and the fault crops up again. So much for that! To be fair to Vodafone they are sending out a replacement unit now but of course i'm concerned that even that will have the same issue.
What are the odds?
Here is the same.
To developers: the fact that resetting the screen fix the problem makes me to ask if there isn't a way to make the screen re-calibrate itself every X seconds/minutes, without shut off and on the screen every time. Seems to be until now the only solution to this extremely annoying issue.
It really is a bizarre one. I've seen people discussing whether it's a hardware or software issue but nobody seems to have a definitive answer. If it were a hardware problem, surely it would be constant/permanent? If it's a software issue i would have thought that somebody would have bug-fixed it by now? Especially as it seems so prevailant.
I'm stumped!
Other than this one problem though i am completely in love with this phone. The device itself feels solid, durable and pleasant to use. Android is improving all the time and it always impresses when you demonstrate to the un-initiated what the device is capable of. So close to perfect...but not quite!
EDIT... This from the wiki.. "- Q5: Sometimes my screen registers touches in incorrect places, and I need to turn the phone off and on to make it work correctly again
A: This is a hardware problem, nothing can be done about it. Nexus One's digitizer sucks.
Ho-Hum.
I have experienced this problem on android 2.1 ever since upgrading 2.2/2.2.1, I haven't had the problem. I'm very happy with my screen

That suggests a software problem although i have had it on 2.1, 2.2 and now 2.2.1. I would say that it has happened to me within three minutes of using the phone, 50% of the time within that three minute window. In other words it's cropped up in half the texts/emails i have sent where i have had to do the screen off/on thing to complete the message.
Very annoying.
It has to do mostly with the way people hold their phones, the possibility of registering false touches - including, for example, touching the screen with fingers that aren't completely dry. Some have the issue more than others.
HW issues still can have SW workarounds sometimes. I'm not sure if it's the case. HW and SW need to be analyzed to find one, if exists.
There is no "calibrating" capacitive touchscreen. Resetting its controller might have effects like missing touches and other random screen misbehavior (for example - if the controller is tracking fingers, resetting it would cause it to lose the tracking).
Since getting my phone back from 'repair' the issue is less frequent, suggesting that it's not a usage problem as i'm obviously still using the phone in the same manner as before. Instead it seems that various devices suffer from the problem in varying degrees.
I suppose if i knew what they had actually done to the phone while it was being tended to it might help us discover why the frequency of the problem has been reduced. I know that the digitizer wasn't replaced as the phone came back with the same screen protector on it as it had when i sent it off. That being said, they obviously did something. I just don't know what!
Most probably replaced the phone's MB.
Try upgrading to the latest radio - the issue will probably not be 100% solved, but now I only get it maybe once a month or so...
I may tell them not to bother sending out a replacement. It's happening far less often since it was returned and (going by the poll results), there's a good chance that the replacement could actually be worse than this one is now.
Perhaps the 2.3 update will jar something loose.
ATTENTION PLEASE!!
after flashing miui latest ROM i've never had touchscreen issues anymore in over 20 hours of hard usage (also with the phone in charge!!).
I don't believe is a coincidence, developers please ask miui developers if they have integrated a code to fix this issues.
Thanks!

I have already restored cyano 6.1.1.
However, about "multitouch issues" I mean inaccuracy, the fact that the touch is recognised in another point of the screen (particularly when you press the bottom part of the panel). I didn't verified the axes-inversion issue, but I'm almost sure that it persists.
The "touch inaccuracy" is nothing else than the usual axis-swapping thing. When accidental dual touches (palm/holding fingers/water/etc) happen, the digitizer goes nuts.

I don't think so....I pay attentions when the screen goes crazy. I'm absolutely sure that (in charge for example) my touch is ONE.
The only times I was able to trigger the "screen nuts" effect, were when I was typing 2-fingered, and fast - making it register dual touches. Moreover, sometimes a single touch with a single finger is reported as series of touches. Once it happens, it stays until screen off.

I mean this....since I moved to MIUI this is not happened anymore.
Since I uninstalled Htcime the inaccuracy issues seem less so far! Almost only with the phone under charge ...much much better than before! Dunno why....

I've scoured the internet in attempt to resolve this issue, and I know it's been talked about many a time before, but this just doesn't have an answer yet afaik.
Does anybody have any experience with fixing the inaccuracy of the touch screen after prolonged use? I love the nexus one, it's by far the best phone I've owned; but this little bug makes the phone completely unrealistic in real-world use.
If this isn't a software issue, it has to be something with the digitizer being powered off and back on to remove the accuracy bug. In that case, is there any low-level way to turn the digitizer off and back on as fast as possible every X seconds? That would mean losing touch capability for a few milliseconds, but is much better than locking and unlocking the phone each time it "goes wild."
I had given up all hope that this issue could be resolved in any fashion as dodgy hardware is, well...dodgy. Nothing can be done about it right?
I haven't had a screen wonk since starting in on the CM7 nightlies many moons ago!
IN YOUR FACE WONK!

No, but it's been covered so extensively that nobody really mentions it any more. Either that or others have found what i have, that somehow the CM7 ROM mitigates the problem. Seriously, i haven't had an issue with it for months!
My particular N1 was never good with stock ROMs. Hated them and gave me endless trouble with one thing or another. It's the polar opposite for me with CM ROMs. Never any issues at all. No call or screen wonk, none of the bugs that others often complain about. It's like the phone has an attitude!
After flashing something ridiculous like 40+ CM7 Nightlies and stable releases, i've not had to wipe data once

Can you please describe what the digitizer issue was/is? I just ordered N1 and haven't received it yet. And what about call wonk? I haven't seen anything about this one.

Basically the digitizer has a couple of quirks. One is that after prolonged use (I found it to be completely random) the accuracy goes berserk, registering touches nowhere near they actually are. Secondly there is a switching of the axis when you cross two points: video. They are hardware related so there is no fix. The wonk is a problem with CyanogenMod7 specifically, causing black screens when receiving calls.
Personally I rarely if ever come across the digitizer problem and have never came across the wonk. They aren't deal breakers but can cause a few problems if you play a lot of multi-touch games.

Well, the touchscreen issue is nothing more than a bad digitizer that was released with the phone and never improved during manufacture of the device. All Nexii have the same one, although people suffered the problem in varying degrees. What would happen is every so often your touch on the screen would register in the wrong place so you may be selecting a shortcut on your homescreen to launch an app, but it might register the touch as being an inch higher/lower/somewhere random. the solution has always been to simply press the power button to turn the screen off/on again. This would fix the issue... until it occurred again.
The call wonk is really in two parts. Stock GB ROMs had a habit of introducing a slight delay in one party being able to hear the other during the start of a call. On CM7 ROMs it was a more significant issue of black screens and freezes during the start of a call. These didn't affect affect everyone though, and even Cyanogen himself didn't have it on on his own device.
EDIT: The other issue affecting the N1 was a weak, and often failing, power button. With the need to keep using it to fix the screen wonk the problem was made worse. That's why you might often see mentions of Trackball wake as it reduced the need to use the power button, therefore extending it's life. Trackball wake is only available on custom ROMs so bear that in mind too!
The phone isn't perfect but with the custom ROM devs doing there thing it's pretty decent for me
Hollow.Droid and DirkGently1 - I appreciate your responses.
Can I bring your attention to my other question to which nobody responded yet?

When the issue happens you just lock and unlock the screen to fix it. No need for a reboot.
This issue isn't really such a big deal. It happens once a week or so, and it takes a few seconds to black out the screen then unlock, problem gone.
This is a pretty big issue that blue up on the OnePlus forum and Reddit. People are experiencing ghost touches in apps. It's very easy to also experience this by opening cpu-z and letting it sit there for a minute or two not doing anything. It seems not everyone is experiencing this though. I have tested and do experience it. Do you?
Yup. Mine does with cpu-z open. what do we do?

Depends if it's a hardware or software issue. Personally I already submitted a return request with OnePlus.
I just cancelled my order.. hopefully there is a software fix for you guys
This only happens to me on cpu-z and not in any other app. So I guess a future software update is gonna fix it.
Left it for a minute and didn't notice anything. On 9.5.3, bootloader unlocked and patched boot image with root.
I haven't experienced in a few days, it was happening a lot until I disabled pretty much all gestures.
I installed CPU-Z just to check on my International 8GB/256 model and I've got no issue with ghost touches. Not sure what is causing this for you all, but I do hope it is sorted out for you all.
When I turned off NFC the issue went away for me glad I don't use it whatsoever haha

Well that's not a solution disabling a useful feature to not have ghost touch issue.
On screen/off screen gesture are one of my favorite using it, so not a solution to me.
Simple will return the device.
I haven't order yet but i will next couple of days.
There's many reports across oneplus forum.
https://www.androidpolice.com/2019/...ros-are-suffering-phantom-touch-input-issues/
I left CPU-Z running for at least 10 mins.
And all is OK. Maybe it's a rouge program or something to do with the unlock\twrp?
The only way to be sure is to reset to stock and only install CPU-Z
Seems OnePlus using Novatek panels https://github.com/OnePlusOSS/andro...input/touchscreen/oneplus_touchscreen/Novatek
Poco F1 had same problems with Novatec and only way fix it was replacing whole panels, they tried to fix over updates but witout luck

Wow that's seems real bummer.
Why would OP use Novatek display controller since had bad reputation and bad track record.
So the question is how do we know if all that units effected having all of the them Novatek display controller?
Or if there's another supplier for those units that don't have that issue.
Man things are getting much worse if it's hardware related and not software that I thought.

It's extremely annoying it has happened to me a few times even when I was boasting about the new device to some colleagues at work. I thought it was me at first until then I read IRS an actual thing. I won't return it yet but I might if it's not sorted soon. It's extremely irritating.

Looks like ghost touches are related to NFC. Try with NFC turned off.

Can confirm. My Ghost touches seize when NFC is disabled.

I've started yesterday experiencing that ghost touchs and also screen not responsive to touch in some panel sections (mostly the upper right zone). The phone didn't gave me that problem since I bought. I noticed when this happening, pulling the notification bar down to the tile settings makes that zone work again. Same thing happened when that random ghost touchs happens.
Didn't had any problems, don't use NFC, tried turning it on, ghost touches started appearing on cpuz, but not on other apps. As i don't use NFC i probably won't return the phone.
I just tried with CPU-Z and a few seconds after starting the app, the screen turns crazy tapping here and there. Can confirm also disabling NFC solves it.
Turning off nfc or not using gestures or not using cpuz app is just temporary solution.
And there's multiple reports that ghost issues happening other app too.
And we never know if thing get worse over time.
I'm afraid it's a more common issue than we thought but many users simple didn't notice it until now.
Oneplus should clearly take attention on that issue seriously and fix it ASAP.
Shouldn't be happening at all with any kind app or scenario of usage.

so in short this problem has plagued the phone since day one and i suspected a HW issue since nothing fixed it. for those who dont know whats im talking about, you are lucky. the issue is basically that the proximity sensor is missed up so the screen will light up when you are in a call or listening to Whatsapp/Telegram voice messages.
The Solution:
The problem, turned out, was caused by the factory screen protector that came already applied to the phone. i removed it after it was damaged and also removed the case (Spigen Rugged Armor Case), cleaned the phone and VIOLA its working perfectly fine now...
i hope it works for everyone else.
So, what you are saying is:
Since when this phone got launched in May 2019, not a single user facing the proximity sensor issue had the ingenious idea to remove their factory applied screen protector and you are the first one to come up with this "fix"?
I am really sorry to be this discouraging but: This ain't it chief.
Good that it fixed your perception of the issue though
Comrade, the issue is far graver than that. OnePlus 7Pro does not have a proximity sensor per se. It uses software (an ai I think) to "guess" whether to turn on the screen or not which is why listening to voice notes gets crazy...

Even though it does have an infrared sensor under the screen (that has been proven), i agree with you that it seems to be using something like that.. Curiously, the proximity sensor once fired when i flicked off my lights in my room.. This indeed leads me to believe there is more going on than just a simple infrared proximity sensor..
But yeah, i don't think removing the stock screen protector "fixes" the thing.. It may improve things but i doubt it's a fix.. As i said, this phone has been out for a while and people would have noticed if removing the screen protector fixes the proximity sensor for good..So yeah, cheers mate.
I took the screen protector off before I turned the phone on for the first time. I still get the screen lighting up while I'm on a call, often muting it with my cheek.
I must be lucky but at the moment I have no such issue with my new OP7P (MFD: 2019/05). RR Rom. Still have the screen protector on it. What's the MFD of your unit ?
i have problem with my oneplus since i rooted this phone
after root i have installed pixel expereince rom
when i called i found proximity sensor not working
now almost 6 months no fixed i'm stock oos
please help me there is no guard on my phone also no cover
The simplest solution for me has been to use a Bluetooth headset. I rarely use it without it.
