I just did this. Will test it out over the next couple of days. I do have ts30 flashed though.

Here are some pictures and steps.

1) Start from the long sides of the device, work a fingernail into the edges and gently work it around towards the top and then to the other side. Remove it from top to bottom. You don't want to force it because the back cover kind of slips behind the USB port and you might crack it.

2) This is the part the OP was talking about. If it's loose for you (it wasn't for me) you can go ahead and reconnect it. As it wasn't loose for me, I used a plastic knife and popped it off without remove the tape and simply pushed it back in.
[Nexus 7 (2013) General] shams6:
[MENTION=2060305]squeeish[/MENTION], can you make a video how to open the back cover and everything -
[Nexus 7 (2013) General] Bogdacutu:
Just did the same thing as [MENTION=2060305]squeeish[/MENTION], right now it seems to work fine (but the problems occured randomly before so it will be a while before I will be able to actually know if it works or not)

[Nexus 7 (2013) General] lomonic:
I have just done this a few minutes ago. Its quick with your fingers running through the middle of the long right side then to the top of the headphone jack and to the other long side. Tricky parts are around the corner but once u get the catch off, it kinda stays off. Once the left right and top are off, just slowly work put the USB bit at the bottom. Not hard at all and don't be overly precious with it.

Anyways the results. I popped up the clip and push it back in again. U can feel 2clicks left and right of it. For me I noticed improvements with sensitivity and accuracy of typing. Am on 4.4 stock rooted and so far so good. For once Google maps was working well just as well as Google earth. I hope it stays the way it is.

Will report back in a few days. Overall only took less than 10mins to take apart and put them back again. Easy peasy.
[Nexus 7 (2013) General] furou:
About a day later I'm seeing improvement.

My touchscreen was working well on 4.4 with my issues being that moving a finger almost on the axis created by another touch would behave like a magnet and that every 20-30 mins the touchscreen would go insane, either barely registering swipes or ghosting up to 5 flickering touches on any single touch (solved by turning the screen off and on).

The magnet behavior is still here but it seems slightly better and doesn't bother me much under normal use anyway. The second issue seems to have gone away which is awesome. Haven't had a problem swiping or no more getting crazy multi touches everywhere. I typed this post on my nexus with ease.

I don't recommend cracking open your device if you don't know what you're doing and aren't ready to face the consequences, but this fix works.

Maybe a combination of securing the cable connection and flashing one of sfhub's fixes is the ultimate cure for the nexus 7
[Nexus 7 (2013) General] lomonic:
I was skeptical with this fix initially bit did it anyways as it was too simple not to give it a go. Anyways following up after 12hrs usage so far and it's been soooo good. Typing is so sensitive and accurate now. No more odd key presses or inaccurate typing. It just works. Also it works lying on the bed now. Single and multi touch. I have to say this is now a perfectly performing piece of hardware.

Give it a go if u can. I'm on stock 4.4 drivers and not using sfhubs fixes. There really is no need to, if u do this fix.
[Nexus 7 (2013) General] LittleConfucy:
Does the ribbon cable disconnect by lifting it up or by sliding it out?

I want to be really careful because I don't wonna break anything.
[Nexus 7 (2013) General] squeeish:
Lifting up. Take something that is flat and made of plastic and pry it upwards on the left and right. Then use your thumb and push down on it flat to reattach it.
[Nexus 7 (2013) General] bokoy:
Did it, in less than 5 minits.

Mine was perfectly attached, I just removed it and cliped it in again making sure that I heard the clics in both sides. No changes at all, I just had multitouch issues, no problems with single touch, and I still have the same multitouch problems. I will try the other end under usb and see how it is.

No luck for me... Also I'm sure that heat increases the problem, and even more watching where it is located next to cpu, gpu and all the heat producing area.
[Nexus 7 (2013) General] lomonic:
After over 2 days with it. things are still going well. It's simply what it should be. everything works as how it should hand-held of laying down on a non-conductive surface like a bed or table. I am unable to explain why it happened even though i didnt have a lose cable, but it works. Perhaps the removal and replug of the cable caused a re-calibration or it removes the built up charges that it had during manufacturing...

Hopefully this stays as we progress with future upgrades :D I have been on sfhub's fixes when i was on Jelly bean and kitkat did improved my touchscreen significantly after but there's still missed touches and things didnt work as well when laid down on the bed or table. Now it's all gone for days and perfect. Highly recommended :D
[Nexus 7 (2013) General] fallout0:
I'm going to be returning my Nexus 7. The touchscreen works mostly for me but it's a bit unpredictable. I was trying to send messages on Facebook with it the other day and it wouldn't register half my touches. It seems to get worse if the device heats up.

I love the device but I don't have any confidence in getting a properly working out so I'm just going to replace it with an iPad Mini Retina. I only use it for browsing/email and I don't want to be dicking around and opening it or replacing touchscreen drivers.
[Nexus 7 (2013) General] lomonic:
Go for it. The hard truth is that most users would not wanna be fiddling with their hardware OR should they have to.
[Nexus 7 (2013) General] fallout0:
Yeah :( Bit disappointing to be honest. I've had the Nexus 4, 5 and 10. The 4 crapped out, the 10 rebooted randomly and now the 7 has issues with the touch screen. Nexus 5 is the only problem free one. I love the Nexus line of products but their quality control is terrible.
[Nexus 7 (2013) General] player911:
Mine was solid. I unclipped the cable and reseated it. Both ends snapped in. Still wonky touch.

Its loads better after Sfhubs fix, but still bad after using my G2 for a while.
[Nexus 7 (2013) General] animania260:
I finally bought a thinner screen-protector. So I took off the old one, I took off the back of N7 and unplugged and reconnected the touch-screen cable. I booted it, used the screen for a while, cleaned it up and put the new screen protector on.

At first there was still issues when not holding it, but a few hours later.... Finally my touch issue are completely gone. I can use it perfectly just like the old N7 without holding it on any surface!

Also all the touch issues went away when I took off the thick ass screen protector I bought from BestBuy.

I'm on stock KitKat and for me KitKat resolved all the ghost touches so try using the KitKat firmware if you do this.

I bought the TechArmor 2nd Gen HD Clear (for 2013 N7). Same brand I used on the original N7. Only about $13 on Amazon and fast shipping. I still have the original 1st one I put on my original N7 and its still holding up good so they are great quality.

My N7 now works perfectly on any surface without holding it! It's awesome!
[Nexus 7 (2013) General] remedya:
In the last couple of weeks the screen has become unresponsive at times. I reseated the cable following the OP's instructions. Very easy and it seems to have fixed the problem.
[Nexus 7 (2013) General] egzoti4en:
I also thinks that this fixed mine two.
[Nexus 7 (2013) General] animania260:
Oops, delete.
[Nexus 7 (2013) General] shams6:
After opening backcover of the TAb, during handling my fingerprint imposed inside of the back cover, while removing those fingerprint by a cloth it got more worse.

Will it hamper my warranty???
[Nexus 7 (2013) General] hkgrob:
It seems to work...

Worked for me.

Well, it seems better anyway, and it took all of 2 mins. :D
[Nexus 7 (2013) General] remedya:
I doubt it would be an issue to worry about.
[Nexus 7 (2013) General] Melaque2013:
I have had these touch ghost issues for a few weeks. Elsewhere on the www I found a cure that called for placing a small strip of plastic, like piece of a zip-tie under the ribbon to prevent it from pinching. This worked for a time, but problems soon returned. Now doing this repair (of sorts) worked, but all I did was open the back, re-seat all ribbons and close it up.

So, maybe I'm thinking re-connecting the ribbons every few weeks eliminate some static electricity?
[Nexus 7 (2013) General] lg777:
I was thinking the same thing but shouldn't that get resolved when you plug in the microUSB as the problem seems to be eliminated while charging.
[Nexus 7 (2013) General] Gorgtech:
This device has some serious grounding issues and I´ve spent some time around, tinkering with the pcb ..

Well, I´m not quite happy about the fact that I had to repair my Nexus 7 II by myself since this is not something a customer should have to do..

This device had slight multitouch issues and weird buzzing noises when using the headphone jack. I´ve spent some time to figure out how to fix the sound issue and was able to fix it by opening the device and tinkering around with the shielding..

The multitouch issue seems to improve if you check the connections to the digitizer but still you can see the touchscreen be agitated in Yamt. Well, I´ve found at least a solution for another important issue, just in case all devices have this one; the buzzing noise when using the headphone jack without any audio signal playing. I can create a thread just in case there is demand for a fix since my method will 100% void your warranty and there is no way to remove the modification without leaving any traces...
[Nexus 7 (2013) General] bokoy:
Mine works worst while charging and the usb conected, of course. And I have also noticed that when it heats up is even worst, I guess that the connectors get hot and the problem increase.
[Nexus 7 (2013) General] dehsA:
I'd love to see someone do a teardown comparing a perfectly working Nexus 7 alongside one with a defective screen. I sent my Nexus 7 in for a repair and it came back slightly better but I still can't swipe my keyboard without touching the device.
[Nexus 7 (2013) General] unibomber:
Do it! I use my tab in my car for music. The Bluetooth stinks for music. Sound is lowwwwww compared to the headphones.
[Nexus 7 (2013) General] LittleConfucy:
Tried but it didn't work for me. I disconnected the battery first, then checked if the ribbon cable was loose (it wasn't) so I reconnected it (Akwardly, it only clicked on one of the sides, but it seemed pretty sturdily connected).

I only had slight single touch issues, (missed and frozen touches, and not very often) but nothing has changed, not even a little bit.

I was really hopeful:crying:
[Nexus 7 (2013) General] nonreality:
Just decided to try taking my cover off to see if it would help with having to hit keys multiple times to get a response. I immediately noticed a major improvement. I ran my stylus in a s pattern from top to bottom and then side to side without a stutter at all. I put the case back on and couldn't get a quarter of the way without pauses and stuttering. Case is back off now and I've typed this post without having to hit any key twice. I thought it had gotten worse over the past 5 weeks but I now believe it's the magnetic case. It's the Moko Slim. Man it feels good to use this again. I hope that is all my problem was.
[Nexus 7 (2013) General] pan.droid:
I use a magnetic case and no issue except for when my fingers are way cold.
[Nexus 7 (2013) General] lotherius:
Reading through this thread is interesting... I have a feeling I might end up needing to do this.

On my N7 LTE, I have at times had it stop responding to taps, but still respond to swipes. Reboot normally fixes it.

However, I began to suspect a physical problem yesterday. I bought a car mount for my N7 so I could use it as a navigation device. The spring-loaded mount is actually (IMHO) a bit badly designed and puts a lot of spring pressure on just four very tiny points on the long sides of the device (two on top and two on bottom).

When I had the N7 mounted in that mount, an area on the left side of my touchscreen would go unresponsive to taps. At first I freaked out thinking my touchscreen was dead. But when I removed it from the mount, it started working again. Put it back in the mount, that same area of the screen stopped responding again....

So clearly pressure on the edges of the device is affecting my touchscreen... doesn't bode well for long term function of the touchscreen.
[Nexus 7 (2013) General] godutch:
For anyone trying this a few small tips:

*If you have the lte version don't forget to remove the sim tray first

*open first at the side away from the USB port (top) to the USB port and close the other way around, starting from the USB port

*the connector pops out, so you don't need to remove the tape, just gently push down on the connector
[Nexus 7 (2013) General] TarantuL_Russia:
had clooadi

I have a problem sometimes with a touch! \

give me repair solution!
[Nexus 7 (2013) General] godutch:
Well typing seems to have become a lot easier. Before the keyboard used to be very unresponsive and I couldn't use SwiftKey but now typing is flawless
[Nexus 7 (2013) General] animania260:
Really... Read the thread buddy.

There is your solution.
[Nexus 7 (2013) General] godutch:
Just got some ghost touches again, they were fixed by a reboot but overall tap sensitivity still seems much much better after applying the fix from this thread
[Nexus 7 (2013) General] furou:
Next time that happens try shutting off the screen for a couple of seconds and turning it back on, it should solve those random reoccurring issues for a while.
[Nexus 7 (2013) General] nomikSqash:
Was thinking to take off the cover but then read 1 post about magnetic cover so I took it off now using device w/o it it is smoother then ever simply will not go to hardware issue. B4 had issue even in multi touch app with ghost touches and other bunch of issue but the. Most annoying was in Google earth when u pit ur fingers to each other really close and screen go crazy after taking off the case everything just work as I would like it to be will not use any case here.

Now I understand why on my Samsung galaxy 4 smart cover does not have magnets on it.
[Nexus 7 (2013) General] astuermer:
I did this hardware fix too.

Most of the time it works now - I can even type with my tab ;)

But sometimes, the display is missing touches - very few times there are still ghost touches.
[Nexus 7 (2013) General] Covart:
Well, I have waited for Google to try fixing my screen issues with software updates, I tried the other multi-touch fix in this section of the forum and finally gave in and tried your fix.

A fingernail and 5 minutes of my time last night have fixed my issue. Not a single touch issue in the last 24 hours. A huge thanks for this. :good:
[Nexus 7 (2013) General] GSLEON3:
Glad it worked. I have been meaning to get back to this with pictures & a better guide, but I bought an Amazon Kindle Fire HDX 8.9 & that has been keeping me very busy, what with getting GAPPS working & fixing half a dozen bricks a day. One of these days, lol... I get back to this & actually have an hour or two so that I can take some good pics showing the internal issues that lend themselves to exasperating the touch screen issues for some users.
[Nexus 7 (2013) General] astuermer:
Tried that too several times.

After a few hours of use - or around 1 day of standby - the touchscreen problems are back.
[Nexus 7 (2013) General] tntgdh:
It seems that my problems were related to chrome. I freezed it and now the problems stoped.
[Nexus 7 (2013) General] Anderson2:
Which problems? (there are many different touch problems: multi touch, freezing, ghost touches, etc. )
[Nexus 7 (2013) General] tntgdh:
Well my nexus stopped responding to touch for a few seconds. Once this problem started I could only remove it by restarting my device. Today I noticed one touch being registered in the wrong place. It didn't happen again, so I got that going for me, which is nice.
[Nexus 7 (2013) General] Pandae:
It might be an app that does this. After I play "Doodle Army" for a while, the controls become unresponsive. After exiting the game, YAMTT shows that my screen now has dead spots and won't register multiple touches properly. Yet everything's fine after a reboot.
[Nexus 7 (2013) General] e2zippo:
Tried this but sadly it didn't work, i still have dead spots. Many thanks though!

[Nexus 7 (2013) General] RR215:
Thanks GSLEON3 ! I had issues with touches not recognised on occasions. Some apps seem to be more responsive than others and so I chalked it up to the OS software issue category.

Now after taking the back off and looking at the cable.....it seemed to be plugged in all the way into the socket. So I just unplugged it with some tweasers as to not lift the sticker off.....then pushed the cable back into the socket.

Booted the N7 back up and now the touch response is vastly better !! Not sure if reestablishing the socket connection at the end of the ribbon cable caused some sort of reconnection sense with the digitizer...but it definitely works better now. And I did not have a big problem like many.....only slight non response touches on occasions. Now the touches seem very quick and snappy.

:good:
[Nexus 7 (2013) General] sokinso:
Quick question zooming and rotation on Google maps works flawlessly for all of you?
[Nexus 7 (2013) General] mhannigan:
Can you please check back in and let us know if the fix seems to last for a while or if the problems return?
[Nexus 7 (2013) General] bokoy:
No, never even when it works "right".

This fixes mine temporarily, but after some time problems are back. I just open and replug, maybe putting something to keep the pressure... But don't know what or how to stick somthing in there without messing.

Any ideas?
[Nexus 7 (2013) General] EtherealRemnant:
I've found that the only time I have touchscreen problems is when I have it in something other than my hands. If I put it in a case, it messes up. If its lying on the couch, it messes up.

I've even figured out that if I need one hand free, I just place my thumb around the edge and I can tap anywhere on the screen without issue.

Its the strangest thing. I've never seen anything like it. I downloaded a multitouch test just to see and sure enough, if its in my case, on the table, or on the floor, it jumps around and sometimes doesn't register at all. If its on my leg on my jeans, it conducts. It also does on my shirt.

I don't get it at all but it works so I don't worry about it.
[Nexus 7 (2013) General] RR215:
Seems you might have one of the early batches made. This was an issue when the tablet was first released. I took back my first one because of it. The last one I got did not have this issue. Try plugging into the charger when on and using it without holding in your hands, that was how I quickly determined this issues when I first got it.

I would see about getting a full replacement if you can, but sending back on warranty would be a last case for you there.

---------- Post added at 10:45 AM ---------- Previous post was at 10:44 AM ----------

Sure, I use my N7 daily, so after a week or several...I will report back if I notice any change.
[Nexus 7 (2013) General] mhannigan:
Thank you. I am not currently having the issue, but I was and I really haven't done anything to fix it. It seems to be a tough issue to nail down, and the more info we have based on real world results, the better.

[Nexus 7 (2013) General] RR215:
Ok now after using my N7 2013 for 4 days after doing the screen cable reconnection process......tablet is still consistently working extremely well in regards to touch sensing. Even with the SPG Ultra Clear protector on.....it registers touches with just slight physical contact and very quickly. Definitely much snappier than before and not sure it could get any quicker in response. I tested with over 12 apps and various areas in the launcher UI. Charged up 3 times and powered on/off several times as well.

I hope it was just some minor flaw of the ribbon contact ends or socket needing some slight abrasion to get a solid connection established. I wonder if some sort of finish element on the contact points needed to be "scratched/worn/rubbed" to allow 100% connectivity with 0 degree loss. Just a theory.

Needless to say......wow I wish I would of done this long ago when I first heard about it. You have nothing to loose if you carefully get the back cover off and reconnect the ribbon cable end. I did have a tricky time at first getting the back cover off around the power button upper corner area. It was not separating as easily as the opposite side and top edge near the camera area. I just worked it slowly and was also careful of taking the cover off around the power plug connector on the bottom lastly.

Good luck to those that have touch problems.....hope this is also a fix for you.
[Nexus 7 (2013) General] martincollar:
dont work for me

Hi everyone, I just did this but after closing back I test it in YAMTT with same result: top half of screen not registering touches. In hands or in charger it is ok. With headphones it is ok also. And it is worst alter playing games (when the tablet is heat).

I unplug and plug the ribbon cable without loosing tape..

Any suggestions?

Thanks

---- EDIT:

I opened it again today. I reconnect battery (i didnt do a battery reconnect yesterday) and that ribbon cable again... After hour of playing Real Racing 3 tablet is heat and touchscreen works perfect! But maybe it's just coincidence. I hope it is solved. I will post there about progress of this..

Thanks OP!!!

My N7 started having multitouch issues about 2 weeks ago. After following your instructions, all my touch issues are gone.

Thanks again!
[Nexus 7 (2013) General] martincollar:
Hi, could you please tell me which cables did you reconnect?

I reconnect battery cable and display ribbon cable on the top (THIS: youtu.be/BUT6bZdITo8?t=6m51s) but not on the bottom (THIS: youtu.be/BUT6bZdITo8?t=6m25s) because it is under the charging module and it has seal on screws.

May be the problem is in the bottom because reconnecting top ribbon cable dont work for me.

Thank you.
[Nexus 7 (2013) General] :
I just pushed in the fat silver looking ribbon some. I pushed and tried to wiggle the thinner copper looking cable a little bit. But that one goes under a circuit board, so I didn't mess with it much. I didn't disconnect anything really. I just tried to push them in a little more. It didn't seem like I did anything but my touches are working perfectly now.
[Nexus 7 (2013) General] martincollar:
I'm out of luck with my nexus.. I tried it today again (reconnect, wiggle, push...) both cables (silver and copper) and my tablet don't register single touches on to half top of the screen when on the table..
[Nexus 7 (2013) General] dakunclear:
I will open mine up in a bit, but last time I had to go back to 4.3 to fix it but right now it's working fine if my touch issues happen in a few days I'll rip it open
[Nexus 7 (2013) General] dakunclear:
Well random reboot has happened looks like I'll be opening it up sooner then I thought
[Nexus 7 (2013) General] JustROLLIN:
I performed this "fix" last night, worked perfectly.

Only took about 5mins to complete and immediately I saw improvements, most notably when using the keyboard, feels incredibly fast and responsive now.

Thanks OP!
