Touchscreen problem - is this a known issue or a hardware defect? - Nexus 7 (2013) General

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.

Is using a case with a magnetic cover against tos?

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

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.

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.

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?

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.

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

Touchscreen dead strip!

I've noticed just today that there's a dead strip on the touch screen. It didn't do this yesterday. The Nexus 4 was dropped once from 2 feet high, but that was almost a month ago and everything worked fine until now.
The screen still looks beautiful, no dead pixels, no cracks, and the phone is in a protective case with a screen protector.
It seems to me that the digitiser crapped out, but I'm not sure why it happened so randomly.
A funny thing though is that when I drag something fast across the strip it works. And sometimes it'll recognise a touch as a long touch or two-fingered touch along the strip. Weird.
I attached a few touch test photos to show the issue.
Hopefully there's a fix. Has anyone else had this problem? And if you had to send it back to Google, was something like this covered under warranty? What should I do?
Sent from my Nexus 4 using xda app-developers app
You can try to replace the screen yourself or tell LG/Google to send a replacement via RMA. They have parts floating around Ebay
How risky/costly is it to replace it myself? And does anyone know if it's covered under warranty? Cause if is, it'll be cheaper just to get a replacement from Google.
Are there other ways to check if it is indeed the digitiser? I've seen that sometimes touch screen problems are software related. And if that's the case, it'll be easy to fix.

Depends. If you follow the instruction properly, it works well. If you screw up, then Google/LG wont be able to help. A lot of people have done it and succeeded. There are great articles on the web. The price of a digitizer would be about $50-70. I MAY BE WRONG WITH THE PRICING.

In most cases no. Because it worked well and suddenly stopped working. Thus Google would say that its your fault. If you are somehow able to convince the Reps that it wasn't your fault, then there is some hope. I

Anything. The phone might have overheaten to the point that it flashed a certain section of a digitizer. It may also be a battery problem that escalated. If you feel that it's software problem, flash a ROM a see if it works.
IMHO You should send it to LG and get it fixed for about $140~.
This problem should be covered under warranty. If you honestly haven't done anything to cause this damage. (I'm also clueless as to what a user could do themselves to make just one section of the digitizer stop working)
Then lasting 5 months or less would not be considered reasonable and you should be entitled to a replacement.
Remember it is down to the retailer to prove that you caused any damage.
And if you honestly did nothing and it just crapped out on you then you should have nothing to fear in sending it back for a warranty replacement

That happen to my iphone when it got water damage. But if you did not do anything wrong, it should be covered by warranty.

I did an RMA explaining everything like I said above. I got my Nexus 4 replaced by Google, and they didn't charge me anything. New Nexus 4 works fine with no issues - I've been using it since May.

Same bug here in Italy where I'm living now even if the the phone was bought last year on UK Play store. Problem is Google rep wrote me RMA can take place only in UK or any other county where N4 was originally available on Play store i.e. NOT Italy.
Does anybody know of a workaround to get the RMA here?
Thanks

Yeah, I think the overheating might have been what happened to mine. I was using a blackberry charger and I think it might have overheated my battery and fried a strip of my digitizer.
Even i have got the same problem, i dont know who bumped this old thread, but please guide me to for a low cost workaround for my situation
No drop or glass break.. Dead pixel just one..
Hi,
Anybody found the reason for the issue, i too got the same issue; a dead strip exactly in the middle of the screen, My warranty is over already, so anyone has work around for this??

This looks like a dead thread, but Ill take a punt. I dusted my old Nexus 4 off the other day, which had exactly the same issue with the dead strip on the digitiser. I had tried replacing the screen and digitiser (I have up trying to get the original screen off the original digitiser). The issue remained, so I tried a full factory reset, but that also didn't work. I am now wondering if I should get a cheap motherboard, or try flashing the stock ROM again. Has anyone else had any luck with either?

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??

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.

So i am now rolling back to the latter and sammobile here i come

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.!?

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..

Hey guys, so a couple of weeks ago I dropped my N4 in water for about 10 seconds, as I was attempting to shut it down the screen flickered and it all went dead.
Fine, so after a week taken apart and in rice the battery is screwed, standard stuff, bought an OEM replacement battery, and then it turned on, worked as it should, except the screen was completely dead, no backlight no nothing.
Again fine, I order a non-OEM screen/digitizer/frame assembly, it arrived today and after being god damn sure everything is correctly assembled I power it on to find the screen is still completely off even though the phone is starting up and working normally (I can hear it unlocking, I can receive calls etc)
Is there another component that has to do with the signal to the screen that may have suffered from the water damage?
Bump. Can anyone shed any light on anything else to try?

My guess is you got a bad screen. There's lots of cheap ones out there. See if you can return it

I suppose it's a shame I can't know for sure cause the new one could be faulty, and the old one could be water damaged in some way.

Hang on, I just realised the digitizer works on both screens, I can unlock it and navigate what I remember from my layout just fine, it's just the display on the new one and the old one, surely that means something else is broken on the mainboard perhaps?

Is my proximity sensor defective?

Hi everyone,
I've just got my new N6P and I found out that whenever I make phone calls the screen turns black and unresponsive until about 10 seconds after the call is ended. I can end the call with the power button and after locking and unlocking the phone the screen goes back to life.
I've read a lots of thread in this forum talking about screen protector causing this problem, but I have no screen protectors installed.
I also tried cleaning my phone very well and some other suggested workarounds: install Google Fit; disable ambient display; disable daydream; disable adaptive brightness. None of them worked.
Finally, I tried installing some apps to verify the behavior of the proximity sensor, but all of them just show that the proximity sensor measure 0cm of distance; of course there's absolutely nothing covering it.
In your opinion, is that a software problem or a hardware problem? Should I RMA my phone ASAP?
Thanks

Try reflash system if you think it's software (you'll have to unlock your bootloader so its recommended to backup your internal storage.)
But to me it sounds like its an hardware issue

Nevermind, I misread.

Don't you think that reflashing my phone will void my warranty?

Nope, as long your bootloader is relocked again, your warranty company won't know

Ok
So, another question comes to my mind right now: is reflashing worth trying in order to solve my problem?

Yes it is. What you're experiencing is most likely a hardware issue but it's worth a try. For the record, even if you left your bootloader unlocked it wouldn't matter, having an unlocked bootloader has no effect on the warranty with a Nexus device. If you need instructions on flashing the factory images I have a detailed guide here:

Ah I thought you had to relock the bootloader for warranty. You learn something new everyday

Thanks for your answers guys. I'll flash my N6P and let you if my problem will be solved.
I asked the store which sold me the N6P and they told me to return the phone without any software modification, so I'm not attempting to reflash it.
Thanks anyway for your help.
Do u have a screen protector on? Some don't have the correct cutouts for the sensor and that makes it read 0.
I have a fairly thick tempered glass screen protector with no cut outs where the sensor is located and it works perfectly. I use Wakeup Touch Nexus which uses the sensor and it works well. Sounds like a hardware issue to me.

As far as I know all screen protectors that cover the glass affect the sensor. Take it off and I bet u it'll work fine. I went through two screen protectors before I got one with the cutout.

He said it's already working perfectly.
Can you try to reboot to safe mode and then try again? Sometimes its just 3rd party apps that are causing issues likes this.
