Does anyone else have a misaligned touch screen?

Is anyone else having a slight misalignment on the touch screen?
For me touch is shifted about a millimeter or two to the right.
I've checked on both my N4 and my sister's N4 and both of us seem to be having this slight misalignment.
Both of us have REV 11 N4's. One was obtained through T-Mobile in January, the other was obtained through Google Play just last month.
I've checked on a few roms. I've tried CM, PA, and Stock with a multitude of different kernels (Franco, Faux, Trinity, CM, and stock).
To check:
1. Enable "Show touches" under the Developer menu.
2. Touch a part of the screen where you'll be able to see the touch bubble and hold it there.
3. Look at the screen at angle to see under your finger.
It's not a big deal, just something I've noticed when I had difficulty trying to use PIE on the left side of the screen. Although, I still would love to be able to get the screen recalibrated to have more accurate touch sensitivity to eliminate the difficulty that I have with CM's PIE.
Another question: Is anyone aware of any LG diagnostic tool to calibrate the screen? I remember back on the HTC sensation there was a file that you could load through HBOOT and get your screen calibrated from there.

Oh wow I never noticed this , I have the same thing, never really had problems with it
Btw I have an older model , so its not just a Rev11 thing

Mine looks like its right on when I test. Maybe just a hair over to the right but nowhere near as far off as yours. Rev11 302K

I'm pretty sure you have OCD. So, take some medicine. Your phone is fine, stop crying. :crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::good:

Nope...

I thought I was just trippin when I noticed the same thing last week
Just tested and confirmed, pretty significant misalignment by about 1 cm, which is a LOT when you're talking about a <5" touch screen..
My next thought is, is this a software issue?
We need more people to test and confirm. But I believe that is what we will find. Software issue.
Anyone with a Nexus 7 on stock 4.2.2, please also test and report.

Wow never thought anyone else was experiencing this, mine seems to be off since I always have to touch a little higher than what I'm going for even nav bar.

Nobody tested a Nexus 7 yet?
I'll test my wife's when I get home and post the results

Could not reproduce the issue on the Nexus 7. Looks like it's specific to the Nexus 4

I would think that it's a software issue. My HTC sensation was able to have it's screen recalibrated. I think LG would have some kind of tool to be able to do it.

Same exact issue here but I wouldn't even notice if I didn't try

Can Kit Kat solve it all for Nexus 7 2013

Hey guys, I was wondering if anyone may know if the new 4.4 Kit Kat will fix all of the Nexus 7 2013 touch screen problems.
Maybe Asus and Google knows it fixes the issue. That's why they didn't rush to help us in the last few months.
Cross your fingers people and hope this fixes all of our issues. That would be sweet.
Oct 28 4.4 I'm thinking.

I hope that... it's been a headache, and that's the only flaw mine has, the fix here fixes it just temporally.

Can't say whether it will or won't but I can say I really doubt they have the fix already in hand and are holding it back waiting for kit kat.
They've never been shy about putting out releases to fix things and a touchscreen fix is very contained and isolated, not something that touches many areas requiring long code reviews.

Can I just ask what kinde of problems you are reffering to? Multitouch problem has been fixed with the latest update. At least mine was. With a multitouch program I placed all 10 fingers on screen and was moving it arround, and it registrated all fingers and arrows were moving very very smoothly. 60fps+. Also, there is no problem with GPS anymore. The only problem which is actually not a problem, is smal buzz from speakers when watching of listening to something at very low volume, but that is reported for all nexus 7 devices because that is how the speakers are made.
You are saying like nexus 7 2013 is forgotten and this 4.4 is our last hope for the device otherwise its useless to use. Which is far from truth. I have absolutely no problems with it.

I don't know, maybe I use the device too much? But I can definitely say ghost touchs and some multi-touch issues are there and persistent. In fact right now as I was writting this the keyboard went crazy, it's really annoying and I don't even want to start with the horrible experience I'm getting with PS Touch(which I use a lot) thanks to this problem. Sometimes I have to reboot the device when it goes crazy zooming while navigating the internet.
For you guys that your tablet is "perfect", fascinating, good for you, but that doesn't mean the problem doesn't exists anymore, you just got lucky.

I personally have no more touchscreen issues since JSS15Q, but if there is another touchscreen fix in KitKat that would be good to the few unlucky ones still having issue with theirs..

The few that had touchscreen problems initially were fixed. 75% of working units were broken in the process. Its a big issue. We have a fix but nothing from Google. There are several screen variances which make it impossible for a single 1 fix all solution.
Google will have to detect each variance and patch accordingly. Probably why it hasn't been released yet because it probably will take a larger testing period then previously mentioned. Even using the XDA fix, some versions can cause several FCs and bugs. Similar to the specific pattern freakout.
With 4.4 on the horizon, it would be best to include it in that. Google probably isn't going to create an OTA and then another one in a few weeks.
Just cross your fingers and hope for an official fix.
GPS was fixed though. I'm not sure about the kernel reboots though. I haven't used the stock kernel nor had reboots since I flashed CM Kanged.

Any source for that 75% number? Without a proper source it is hard to not consider that as a case of the loud minority.
If it were that serve of a problem we would hear the tech press clamoring about it by now. But nothing was said about N7 touchscreen by the tech press since JSS15Q.

I can't tell you what the real percentages are, but the touchscreen issue is definitely a much bigger problem than your standard problems.
Standard run-of-the-mill issues get a thread with maybe 20 posts. Touchscreen is producing 1000 post threads. So relative to normal problems it is a big problem, but whether that is a 5% vs 1% problem or a 75% vs 1% problem I could not tell you.
There are at least 3 huge threads on Google support forums about this problem:
Multi-touch - reports of improvement, no improvement, and some worse
Multi-touch (continued) - more reports of fixed / not fixed for JSS15R
Multi-touch (continued 2) - more reports of touchscreen issues
BTW I created the xda fix for touchscreen so I'm very familiar with the fixes Google put out and whether they have fixed the issue. JSS15R fixed it for some screens but made it much worse for others.

That's the main reason I haven't sent my Nexus for repair, is not hardware related, or at least that's what I think, please someone correct me if I'm wrong.

Well, actually it is hardware related, but you can't tell if your hardware is one type or another without using Sfhub's process.

Well, thanks for confirming

I personally don't think that all of the touchscreen issues will be fixed with Kit Kat. I feel that Google will he focusing more on a fully operational OS, and that we'll need a dedicated fix to solve our problems.
But I surely hope that I'm wrong.

At this point, questions to me are almost meaningless to ask. We night as well wait for tomorrow. It took long enough to arrive.
It just sucks that I don't have my tablet. I went back to Radio Shack and ordered the 32gb through them, since none of their stores had that version on their shelves, and 16gb was not working out for me. At least I'll get to download it as soon as I get my new device!

That's a hardware issue, I suggest you to send it back to Google.

This process doesn’t wipe the tablet, so your settings, apps and everything else should stay in tact whenever you get back to the system. Remember that you will have lost root at this point, but it’s easy enough to get that back.. Cool resource!

But before kitkat my GPS worked very well

4.4: Touchscreen issue fixed

So I updated to 4.4 yesterday with adb sideload. Since that I was using my Nexus 7 "heavily" and I always had "buttons stucked" on keyboard, but now it's gone and I havent experienced any other touchscreen bug.

I don't think I have had any buttons sticking since I updated as well. That was my only issue with my Nexus 7 when in was still running 4.3. It would usually have a keystroke stick several times while typing things and I haven't experienced it once while typing this entire post, which is also why it keeps going because I'm trying to keep typing to see if it'll happen, and instead I just keep making spelling mistakes.

It did not fix the touch issues that may be related to grounding. In a case or stand, both Nexus 7 devices I have still fail to see any touch on numerous occasions, even single finger touch events. Manufacturing issue I guess, but we all know how G & Asus deal with those.

Let's hope it lasts... some issues are fixed temporally.

touchscreen is definitely improved for me too.

Yeah but multitouch still fails, playing dead trigger 2 could be an impossible mission.

Never had multitouch issues, only single touch problems like quad touches innstead of one etc. (As u can see it happened again lol)
They poped up after the R update, and im waiting for CM11

I had single touch issues even after sending my tablet in for service. I had called yesterday to send it back again when I noticed the update was available for side loading.
After the update my screen is behaving!
I'm going to hold off on claiming that my issues are completely resolved but it is looking promising.

Touchscreen on 4.4.2

Could you please report if your touchscreen has gotten better or worse afer the update?:fingers-crossed:
Some people are saying that it fixed everything for them, but I just saw someone who said that multitouch has become unusable...

For me it definietly made it, and as I see it became smoother...

But the ghost touch bug is still present. I think this is hardware issue but cannot find any service manual to investigate

Good as gold as with all releases since 4.4

nothing changes

I've seen a little bit of improvement, but I also only had problems under some app-specific conditions. Though, I've noticed the N7 is unusually sensitive to hand/finger temperature. If my hands are even remotely cool, I can't get anything to work. Meanwhile, my S4 in a condom Otterbox Defender reads touches just fine even with freezing hands.

Its not good! i have problem with multitouch and battery life is down!! and i see a bit lack in this new version!(4.4.2 - Nexus 7 LTE ) .... pls Help me .... how to fix it?

4.2.2 almost fixes my DEB model
Hi,
My tablet is one of the unlucky ones which were not fixed by sfhub's patches.
Fortunately, the 4.2.2 OTA makes my tablet smoother. Except for 1 inch strip of non-responsive space (little below the top vertical position), things work fine. I see no ghost touches and multi-touch works fine as long as I dont touch that 1 inch part.
Hmm, it takes 3 OTAs and lot of belief in customers like me to get to this state!

Perfect so far since 4.4. Also, tested ungrounded with one and two fingers with Google Maps and no issues.

I haven't tested 4.4.2, but I WAS using SfHubs ts20 on 4.3.
I flashed the TouchScreen Unlock and then back to 100% stock 4.3 and updated to 4.4 naturally using the OTA procedure. Then updated to 4.4.1.
I tested all along the way and it seems to have helped some. Typing isn't as big as a problem but there are still missed touches and generally sucks trying to play action games. 4.4.1 seemed to help a bit again.
I'm going to try this again with 4.4.2 since I've heard good things. If this doesn't fix it, I'm sending it off to Asus. I've heard they are now replacing the touchscreen driver boards with different ones which basically means it is a hardware problem and they know it.

I haven't tried the "stock" drivers yet, still using TS09 but I will revert back tomorrow.
I got a old Nexus 7 from my mobile operator the other day.. damn, what a dream touch wize.. Why cant Nexus 7 FHD work like this? :/ I can actually TYPE on the old Nexus.

Mine seems to be mostly resolved since 4.4.

Touch Screen Problem may not only on Z1

So far I've seen lots and lots of people complaining about the touchscreen malfunctioning on the Z1, saying that this is a hardware problem and thinking of buying a Note 3 and G2... But then, you maybe have never knew, that almost all the other phones out there have the same problem as we do.
LG's G2 : http://www.youtube.com/watch?v=fAP5iL_xamY

As for the Nexus 5, I have not seen any videos that suggest that it has the touchscreen problem,
But this : https://www.youtube.com/watch?v=5XEvM2nGRmk
I think that all these manufacturers such as Samsung, LG, Sony, etc... Use the same Sypnatics touch digitizer.
Please don't criticise my post too badly if it's stupid, I'm just trying to help everyone
EDIT : For Xperia Z1 it's worse maybe because of the Aluminum frame...

Hey guys I have a tip for ya'll who have the touchscreen problem, go to Settings > Launguage and Input > Scroll down the pointer speed and make it to the slowest. It has lessened the touchscreen bug from happening for my device. Hope this helps

Gg nice post, ao people get some prespective. Z1 is an awsome device, damnit 6 hours brilliant screen time on a 5inch Fhd, i've seen battery report from g2 averege is 4.5 hours like ours, and can get to 7 with power savings. Z1 rocks

Screen problem is hardware problem due to aluminum frame. Screen can't be fixed by update... If you wanna fix screen problem... sell your phone.

Any proof for that? I might fully believe that since xperia SP also has the same problem both have aluminum built.
HTC one also is made of aluminum. My Final solution really is to sell the phone but in the even that there can be some possible fixes to reduce or completely remove the problem then it's great. Maybe hardware remedies or software. For now I'll just wait and see what 4.3 will bring.

Not really sure about that, on mine there is no such thing influenced by the aluminum frame, I did 1000 of test and videos. Sometime it come, sometime it vanish, sometime I can't open the lock screen via pattern if I leave the phone on the table.
