Getting a better look at this multitouch issue, with some good ol' community feedback

Hey guys,
Thought I'd post this here and keep you guys updated on further developments.
I live in the Netherlands and bought a 32GB version at Dixons at the 13th of November 2012
I had found the touchscreen a bit unresponsive sometimes in the past.
But couldn't really find out why it was acting up. I finally isolated the issue.
It is exactly the same as this guys vid:
(Thanks for the vid injahnet)
Together with a little backlight bleeding, I decided to send for repair.
(The problem persisted after a factory reset, no other apps were open when testing.)
I went back to Dixons and showed the problem to the Dixons dude.
He acknowledged there was an issue and sent it for repairs or replacement.
Due to the holidays this can take some time. Maybe even next year
I was about to open my tablet for a look inside one of these days, boy am I glad I didn't do that yet
Anyway to get a good view on this issue globally, are there more people that have the same issue?
You could go to: Settings > Developer options > and then under "Input" you can enable Show touches. and try to to the same procedure as in the vid. (Thanks Peterk-1)
Or you could test with MultiTouchTester like Injahnet.
The weird thing is, my dad's N7 16GB does the same.
Update 17-12-2012: Please do not test while plugged in as the device will be grounded and the issue will not occur. (Thanks dad)
Feedback is really appreciated!
Please vote in the poll above!
Cheers,
Daan

I have zero problems with multitouch while using my Nexus 7. Working just fine, but you must disable any apps which interfere with gestures or it'll steal events.
Can't say I've ever used multitouch with the N7 laying on a random object however.
But sure, send it in for repair......... I'll keep using mine.

If anyone thinks they have multi touch problems then loading an app isn't required. Just go into Developer Options and under Input you have two options to display touch and track detail.

I've done a factory reset before I tested No apps are open except MultiTouchTester
It's in for repairs

Well... Over 200 views. And only 4 votes, which includes mine
Community feedback is failing hard.
Anyway, I'll keep you guys posted on the repaired Nexus.
At the moment of writing we know that three people are having this issue.
I know someone else with a nexus I'll check if he has the issue too.

Yes, i have this problem. And only while device is laying on the table.

Wow, this is bizarre, thanks for pointing it out. I can confirm it happens when it's laying on my pillow, and doesn't when I'm holding it.

Thanks for the vote guys.
By the way, it seems obvious that the Nexus should not be plugged in while testing.
However I cannot test this 'cause mine is at the shop
Would anyone be willing to test?
I'll add that in the original post (+ a mention of your name and a thank you of course))
Cheers,
Daan

Mine was unplugged while testing.

if the two touch-points got the same X or Y coordinate my nex7 does only detect one of them. i don't think this is an issue.

However, zooming in Google maps for example will become quite difficult

Anyone try and see if taping the ground pin on the wifi antenna fixes the issue? This seams like a grounding problem.

Exactly! I was also thinking of this.
Do people who have this issue also have the flickering issue!?

Just an FYI, I installed CM 10.1 with Trinty Seven. Now I get 10 touches on pretty much any surface.

I don't have a multitouch issue, but I do have an entire band on my screen which has stopped responding to touch at times. It all started when I let my tab shut down due to low battery. Initially, the Nexus 7 neither charged (when put on charging, obviously), nor did it boot up. After trying for several hours, somehow it started charging. And since then, sometimes certain areas of my touchscreen become unresponsive to touch. Since the band which is unresponsive is towards the upper part of the screen, using notifications becomes completely impossible. It keeps 'snapping back up' when I try to pull it down, cos while I am pulling it down, the notification tray encounters an unresponsive area, so it just goes back up. Called up Google and they will be sending a replacement device. All I am afraid about is that I have an 8gb version, and they would be sending an 8gb as well, so I hope it isn't refurbished or something, as Asus has stopped making the 8gig model.

I'm having an issue where the screen, ( mostly in a webpage or document,) starts moving up and down and zooming in and out without my input.

Just tested this out and yes, my device is doing it too. Interesting. No other issues like screen flicker (except the auto brightness bug in 4.2). My n7 is c9O

community feedback is not failing hard, more like you're just starting a new thread without bothering to search if issue/topic already exist.
this isn't new and there is no fix, that is just how the touchscreen function. the N7 isn't the only device to have this.

You are kinda missing the point of this thread.
It is to see how many people have this issue.
There is no thread capturing that in an easy way unless you want to count every post.
Now please tell your brain to start functioning again and leave this thread alone if you have nothing to add.

Asus Google Nexus 7 32GB touch death zone
Hi DaanJordaan,
Found out that my brand new N7 seems to have a similar "no touch zone" issue; an area the size of my little finger on the left lower part of my screen does not seem to react to touch! It interferes with typing the keyboard in portrait mode (no keyboard problems in up-side-down portrait mode).
When I use the Easylabs Multi Touch test I can see the dot changing color when I move over this area, doesn't happen anywhere else on the screen..
Using the developer tools (turning on the two options that allows to show touch/leave a trail of touch) it becomes even more clear that this area does not react to touch! I can "paint" lines around the "no touch zone" (it actually splits into 2 touch areas using one finger around the "death spot"), and the "no touch zone" reveals itself by not showing any trail/history line of touch..
Oh yes, and it does not matter if I lay the N7 on the table, or hold it in my hand, the issue is always there.
Therefore I returned the N7 back to the MediaMarkt, and they will send it in for repairs...
I've got a bad feeling about this | - )
I am curious to hear about experiences with your N7, once you have it back!
I'll report mine here, in three weeks or so (that's the outlook...).
Cheers!
NeverMind

The method of reproduce the touch screen problem is established. Confirm it!

1.Turn on your display and wake app like the paintsoft.
2.Put your Z1 onto a insulated one, like rubber sheet and your Z1 has to be naked.(without any cases)
3.Wait 30sec or more.
4.Draw a line, and during drawing, touch the side panel. Left side and right side should be touched by two fingers. and cover of microUSB port and sim port should not be touched.
5.About 70-80%, You can reproduce the problem.
The movie is here
http://youtu.be/CeAw17LrdKE
This problem may be caused by bad insulating.
But I don't know this problem is occurred in all Z1s.
This problem of touch panel can be occurred variable timings.
People who playing games or using pattern lock will recognize this problem easily. but difficult for who Not playing games or Not using pattern lock.
This method can detect the potential error of your Z1 it looks no problem.
Please test your Z1. and if the problem is reproduced, you should go to store and make a claim!
and replaced one if you get, please re-test and report here.

My Z1 also have this problem. After 40seconds i even didn't have to touch this two sides of phone.

For few weeks I never saw that problem on mine so I was not worry about it but today I tested few nice games and I realized that after a minute playing the game (Minimotor or HAWX) the virtual joystick stopping working. I have to retouch the joystick with my hand or take off my hand from the phone. All the time.
My question: this is a Hardware problem?

This ploblem can solve by updating the driver software. like Xperia tabletZ.
Hang in there!

In the next week i will buy this phone when i have enough money.
How often come the problem?

The touch panel is too sensitive?

How it's possible the problem of the touch screen is because is too sensitive? I hope there is a solution via software but for there is some lack of insulated between the touch screen and the rest of the phone. That why when you touch the frame the touch respond very badly.

I think the screen react to very few electrostatic.like touching side panel.
so to make less sharp ,It will be ok. perhaps.

Confirm the problem in my device, hopefully a fix can be found, mine ain't so bad I guess cos it happens only when I press the sides

Actually, It is reported that replaced one has this issue too in Japan.
Sony don't recognize this issue yet!

I did a video by myself and I don't get it! Where is the problem? I mean where is the problem causing the touch screen failing to work. The only 1 thing what I am sure is if I leave the phone for 20, 30 seconds the issue show up with my touch screen with or without touch the aluminum frame.

I can attest to this one as well. Issue occurs especially when gaming and prolonged touch on the screen and without even touch the side panel.

Exactly, I think we are close. The problem appear after long or prolonged use with the touch screen.

No issues here, i tested for like 20 minutes and its perfect here
No issues with games, paint or the service test
So maybe the C6906 doesn't have it?

[Q] Screen keeps flickering

Hi all,
Recently my Moto X developed a screen issue. When I load any application, the screen flickers as if the window is being pulled to the top of the screen. The screen will flicker about 3-4 times, during which I can't get the screen to respond in any way.
This started happening after I installed the Google Now launcher, I've since uninstalled the launcher but the screen flickering will not go away.
Does anyone have any idea what is going on and how I can correct it?
Thanks!

Are you able to get video of it with another device? Is it the actual backlight that is flickering, or just the elements on the screen flashing around?
You described what sounds like the notification shade being pulled down. I've noticed that I get erratic behavior with my Moto X if there is any moisture on the screen (even a few very small drops), and some chargers. I used the BlackBerry charger that came with my Storm 1 because it had a very long (4-5 feet) cord on it, but it seemed to cause issues with the touch input. I switched to the cable that shipped with my phone and haven't had any issues since.
Maybe try wiping the screen down real good with a microfiber cleaning cloth. Not sure if screen protectors could cause this either, but I would imagine that they could interfere with the touch screen if not applied correctly or designed/made well.

Thanks fury683! Yes the elements on the screen flash around, very similar to what it would look like with the notification shade being pulled down.
I've given my phone a good wiping, it's behaving so far but we'll see if it's for good.

Have you tried restarting the device? Just try different little things and you are bound to find your answer.

LOL - I had a moderator move it to Q&A. It WAS in General (wrong section). You were correct indeed...don't worry, you aren't losing your mind

Did you fix your problem?
I am having the same issue where my screen will flicker a few times as if another app is being opened by the app switcher. I noticed it happens when I am connecting or disconnecting from Wi-Fi. I tried factory resetting my phone and it did not help. It is very strange. Did anyone else experience a similar problem or find a cause?

Having this issue too — screen flickers when moving back and forth from wifi to 4g
Yes! Took me a while to connect it to offline/wifi/4g transferring, but my screen flickers 3 to 4 times (basically the view refreshes the same way crappy apps that didn't bother programming a transition go from screen to screen) every time I access an app that uses the internet after this transition between data sources. It is infuriating. Anyone ever resolve this?

Got it — I used Titanium Backup (on a rooted phone) to kill MotorolaOTA (backed up first).

Touch screen unresponsive at the very bottom

All of a sudden the lower part of display (about 7 mm) has become unresponsive to touch which means no more gestures (swipe up to get to home screen is not working) e struggle to use the classic navigation buttons.
Sadly I had the same issue in my mi5 but in that case phone had the issue since the unboxing.
I'm starting thinking the xiaomi touchscreen tend to be more fragile than others.
Now I'm waiting for gearbest support.
Anyone has any advice or similar experience?

Regarding Xiaomi Quality
While climbing into my truck, I dropped my Mi8 from a height of about 4 ft on accident and it landed flat on its face , on the concrete. Freaked out, I left it laying their for about a minute fearing that the screen had been smashed into a million pieces. However, I picked it up to see that it was fine, and not a single scratch. So I immediately went out and bought the Love Mei 360 case.
Anyway, regarding your touch issue, you should really provide more some information about how this issue came about, what rom were you using, did the phone get wet, etc.
Also, I had an issue with my Mi8 soon after unlocking the bootloader where the top part of the screen would not register my touches, I first tried recalibrating the screen using Miui hidden settings app, the test is called QMMI ( I think) and if I remember correctly there are several menus of testing that also calibrate the screen for me this worked and for good measure I reinstalled a Miui rom and havent had the issue since.
Try it, hopefully that is the only issue. If you are using a AOSP. It's possible that you have a driver issue. So before sending the phone off for service its worth testing.. If you are on stock and still have a locked bootloader, I would try resetting the phone before trying anything else.
Good Luck.

Some gravedigging, but the question is still on the table - have you managed to fix it?

S10 plus touch sensitivity not working

I have a stock s10 plus. at first, the issue happened when I tried to pull my notification panel down but realized touch screen isnt working but its localized toward the top. Over the next few days, the area spread from top of the notifications bar to half of the screen and finally to my fingerprint scanner. I though the display is damaged but testing it with *#0*# test prove its working. locking the screen and unlocking it seems to fix it temporarily but it happened after a minute or two. my device feels laggy when the display is working normally. No visual damage nor did I damage it in any way

Possible water damage?
It sounds like mobo issue... as the display tests normally and firmware doesn't fix it.
Try a hard reboot.
