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!

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

Touchscreen problem - is this a known issue or a hardware defect?

Hi,
i own my nexus for one week, and today i used a smart cover which caused some troubles.
first all worked like a charm, close the flap, display off, open it, display on. magnets, how do they work? ****ing magic! :laugh:
well, a couple hours later the touchscreen wasnt responding after shutting down the display. at first, after opening and closing the flap a few times the touchscreen worked again, but by now its totaly ****ed. if the display shuts down, all i can do is pressing the power button for a couple seconds and then start again. (it has nothing todo with the smart cover, i think it was just a coincident)
heres what i have done so far:
- factory reset
- flashed the stock rom (i only unlocked the device)
- re locked the bootloader (mainly because im pretty sure its a hardware issue and i wanna return it...)
is there anything else i can do? i know that there are many issues with the touchscreen, but from what i read, its about ghosting and other glitches, not a complete breakdown that can only be fixed by rebooting and occurs as soon as the display shuts down.
thanks for your help!

What brand of smart cover/case are you using? and do you still have the same problems even without the cover?

yeah, the problems are even without the cover. i thought there was maybe a problem that the hall sensor got magnetized or whatever, but that doesnt fit with the symptoms.

Yeah seems that it's more of a hardware issue that was probably caused from the case if anything. Good thing you already re-locked the bootloader since I'd suggest returning it for a replacement. Just don't mention anything about using a case . If you do get a replacement, maybe try a different case to avoid the same problem.

No, otherwise why would they have put the sensor in the device to react to it?

Major design flaw?

the physical home button was something I did not think would bother me but it is a major design flaw. When putting the device in a case and closing the cover while in sleep mode the cover presses the home button taking a tablet out of sleep mode. so as I carry the tablet the screen turns off and on. this is with a case that uses the four corner tab design. Hopefully, a different case design will solve the issue.
This is the only issue I have had but it is driving me nuts.

hopefully with root we'll be able to disable that. why they chose not to recess the button is beyond me.

I wonder if a case that activates auto screen off and on blocks that from happening.
Does anyone have a case with that built in that could let us know.

Is it a fitted case for the note 2014 specifically or is it a generic 10 inch case? I'm just not finding it on bestbuy.com

he note 8 still comes on with the magnetic case. I cant find where the sensor is on he note 10 . it's too dark and I'm bout to sleep.

Thanks for the info...There are two sides to this coin. It could be a design flaw that the case accidentally clicks the home button. Isn't it their responsibility to design the case properly?

Note 8 has the same button design, I have it since the release date with Samsung's book cover, it hasn't been a problem. Waiting for a similar case for 10.1.

I'd like Active Display(breathing) more if it wasn't so sensitive...

It's definitely not a battery issue, but it bothers me whenever the slightest tap sets off the clock popup. I don't think it's a case issue since I use a light-weight one (Poetic slim case). I would like to think that the context-processor responds to the disruption in the magnetic field which is why it's so sensitive. I can't test this though.....Does anyone happen to have a flip cover for the Moto X?

I use an app called uListen so I can stream YouTube videos with my screen off. I've noticed that app makes the active display go nuts.

It acts when the phone moves simulating you picking it up. When I'm on my recliner it activates every time I move in the recliner. It does what it is meant to do I like it for checking the time and not having to activate the phone.

Turn the phone over so the screen is facing down. Problem solved.

I love it. I pick the phone up and just swipe to wake. Then with a Nova Launcher gesture (swipe up to toggle Quick Settings) and a custom Sleep tile in the bottom right thanks to GravityBox, I've probably cut my mashing on the power button by probably 95%. I barely have to touch it anymore.

I love the active display but it does annoy me when I'm driving. I stick it in the cup holder and every time the truck moves, the screen turns on and I can see it out of the corner of my eye. And I don't know if anyone else lives in PA, but trying to avoid the potholes and inevitably hitting one keeps the screen on almost the entire time...
I also found I now pick up my Nexus 7 expecting the screen to turn on automatically

Hahaha, I've done the same with my Galaxy Nexus and even my wife's Razr Maxx.
PA here too... and the potholes have become unbearable.

I really like the sensitivity... I think its great that it will pop on virtually anytime I move the phone, but not to the point of wasting my battery. I swear there have been times where I could just wave my hand over the phone and it would flick the time and lock up, but maybe it was just in my head.
I hear ya all on the Nexus 7 deal, I do the same from time to time, just expect it to turn on. Would be something easy for Google to add moving forward though.

Well that just defeats the purpose of the active display
But mine is very sensitive as well. Even when there is no movement I will see it go on . Doesn't really bother me. Only when I use another phone...I end up shaking the phone to get the active display to show

Do you Assist app for driving? I've noticed that after I'm driving for a couple minutes the phone must turn down the active notifications as it won't turn on with little bumps. Sometimes it won't even turn on when I pick it up.
But sitting in my house, it'll turn on every time I bump it.

Cover the proximity sensor and it'll assume it's face down or in your pocket.
The proximity sensor is on ALL the time, and it is used in conjunction with the accelerometer to turn on the screen. If you don't want it to turn on in certain situations, do the above.
I cover it with my microfiber screen wiping cloth sometimes when I want it face up but without AN.

Think I'm boned, figured I'd ask anyways...

So I think my 6P screen just up and died, completely out of the blue. I was using it minutes earlier no different than I usually do and it wasn't dropped or exposed to liquid, etc.
So the phone was charging and the battery light was on so I know it was powered on. I went to wake the device and was unable to. The screen VERY QUICKLY flashes like it's trying to turn on and then turns back off right away. Only the middle of the screen attempts to light up. I can actually see a brief flash of my notifications on my lock screen. I figured it might just be a hiccup and force powered down the phone by holding power. I tried to boot it again and still no screen, nothing is happening. Eventually the battery light comes on, so I know it's booting up.
I was able to use ADB to backup my files and reboot to bootloader and used fastboot to flash factory images. Sadly, the issue persists. Phone is long past both Google and Huawei warranty programs. RMA doesn't seem to be an option. I'll be fixing this myself.
I guess my questions to anyone with insight are;
-Has anyone else ever ran into this and managed to fix it? Unlikely, but hey...
-Does this sound more like a display issue or a motherboard issue? Or something else entirely? This being my primary question, really, as it matters for which parts I'm going to have to buy. I would guess the motherboard since the display wasn't dropped or exposed to liquid/fire/heat/cold/explosions/radiation/alien probing/12 rounds with Rocky Balboa/etc., and it still makes an attempt to turn on. If it was the MB, would it even boot? IDK, that's why I'm asking.
-Any reputable vendors which sell quality parts for the 6P? I've had hit or miss experiences with phone parts in the past and I haven't taken anything apart since my N5 & GNex.
Thanks for any help you can offer.

Maybe the solder is bad could try 200 degree oven for 10 minutes to see if it that fixes it?

Possible, I suppose. Thanks! I'll give that a shot as a last ditch effort. I called Google just to see if they'd RMA it, told me I was out of warranty which I knew was the case. They were getting transferred to Huawei for a conference call with Google and them and Huawei disconnected. The Google rep said Huawei has actually been surprisingly good about taking care of certain out of warranty issues. 30 minutes on hold with them, we'll see how it goes.
I think that's a possibility since the screen keeps doing weird things. Blinks on for a half second on the top right of the screen, then the left, the middle, the bottom. Touch absolutely works across the entire display even though nothing shows. I was able to guesstimate the encryption pin entry to finish booting which allowed me to ADB pull all of my files (silver lining, I guess). It vibrates when I touch it, etc. If the oven trick doesn't work I'll just solder it myself and see if that fixes. That would be nice if I didn't have to buy anything!

I think Huawei is putting up a front to Google to look like they are doing good but lots of bad reviews on the forum glad I paid for the warranty first time and only time I've had to use it twice so far this last time they sent me a refurbished phone wonder how long I can do this for this may be the last phone I will actually want

Thanks again for the input, could you do me one last favor anytime you get a chance? From the bootloader, what's the key combo to power off the phone? I just want to turn it off. I can power to the bootloader, but I can't remember the key combo to POWER OFF. I know 6P has some others like barcodes, etc. Not sure if it's up twice, down once, etc. If you can't no biggie, I guess it can sit at the BL until the battery is dead dead.

If it started on start it should be three down

If you have an Amazon Firestick or a Chromecast does it show up as an option under screen mirroring? I believe if the cpu and gpu can render the image for screen mirroring, then you know the display is bad or the connector needs to be reseated. What do you think? Edit- but you would need to enable wireless display for that it's early, I will keep thinking of ways to narrow it down. The voice command open display settings will get you halfway there.
Or have a look at this. The only trick will be finding the touch area to allow the adb key. http://www.techrepublic.com/article/pro-tip-mirror-your-android-device-on-your-pc-with-ease/

Sounds exactly like my screen failure.
One minute working, reboot. Dead.
I had to get a warranty replacement. (Nexus Protect $79.)

Did you purchase directly from Google? I've had my 5X since 2015 and it entered an endless bootloop last week. Gave Google a call and they offered me a one time warranty replacement because I'm in good standing and long time user of Google Play products. Worth a shot?

Not directly from Google Play. It was pre-ordered from Project Fi. When I called Google support about it, they transferred me to Fi which said they'd have to transfer me to the manufacturer, Huawei. They told me there was nothing they could do, call a local repair shop. I called a place in town and he offered to take it apart for me and try to reseat all of the connections and if it started working he wouldn't charge me. Otherwise a replacement would be $200 :/
I'm taking it there tomorrow so hopefully it's just a loose connection and starts working again. Touch seems to work fine all over and I cleaned the screen and put a light on it just to make sure there wasn't any cracks I didn't know about. Looks fine. I'm optimistic, lol. I think $200 is kind of steep, but he said it also comes with a lifetime warranty, so I guess that helps ease the pain a little. I need it fixed ASAP though. My backup Nexus 5s battery is shot. Takes like 12 hours to fully charge and discharges in about 2-3 hours.
