[Nexus 7 (2013) General] Speaking:
Check the three connectors on the wider, silver cable that has one connector on one end and two smaller connectors on the other end. I did not touch the narrower, gold cable.
[Nexus 7 (2013) General] squeeish:
Reseated all 3 of them twice, including cleaning with alcohol. I still have that dead horizontal spot. Guess I'll have to live with it.
[Nexus 7 (2013) General] vulpine:
I have finally applied the fix and there have been NO touch issues since a week Thanks a lot.

I also made a video about the fix

[Nexus 7 (2013) General] lyman123:
The OP solution is still good

1/2015 - Just and FYI. My screen stopped working this AM after acting flaky last night and I was thinking this was a goner (I stupidly bought a refurb). However, a quick Google returned this thread and I figured I'd give it a shot.

So far, loosening and reseating the screen cable is working like a champ - in fact, it seems to work better than before.

So, if your N72013 is giving you fits for the touchscreen, I highly recommend this - it's quick and simple and might do the trick!
[Nexus 7 (2013) General] angel_1975:
I noticed I have some ghost touch when power connected
[Nexus 7 (2013) General] lmacmil:
I am actually having more touchscreen issues since the Lollipop upgrade than I had before. And I still get the occasional random reboot.
[Nexus 7 (2013) General] koymoy:
worked

Had no effect from unplugging/replugging the cables, but noticed that if I applied an small amount of pressure on the silver cable just beneath the top connection, everything would work again. So, I have put a small amount of sticky fix between the back cover and the silver-cable before clicking the back-cover on - still works so far :)

Thx for the posts!
[Nexus 7 (2013) General] moe6:
Fixed mine with the help of your video. Thanks!
[Nexus 7 (2013) General] gusnd:
I have the same tablet with the same issue here, which only happens when the tablet is over a plain surface, like a table. I decided to open it and follow the procedure in the video (https://www.youtube.com/watch?v=cOnccu6Nbl0), but that did not change anything.

Afterwards I decided to verify if it was a connection issue, removing the silver flat cable from its contacts and putting it back again. I lifted the small clips before pushing it, so I did not force anything, but after that the tablet won' power up anymore.

Did the flat cable got broken? Should I get a new one?

Unfortunately ASUS does not support this product here on Brazil, so I can't even ship it to them, any ideas on how I could fix it?
[Nexus 7 (2013) General] Batavian:
Ditto for me. Used your instruction video and worked like a champ. My screen is more responsive than the day I first opened it out of the box. And auto-rotate works flawlessly as well.

I wrote you a positive comment under your YouTube account. Thanks so much for your help. Also the help of other nerds here on XDA. Searching the forums led me here. Smart people. Thanks to all.
[Nexus 7 (2013) General] mayurh:
i opened up my n7 but my cables were in properly

no idea what to do now
[Nexus 7 (2013) General] ahow628:
I've disconnected and reconnected all the cables. I've tried to eliminate static shock. I've rolled up insulation tape and sandwiched it between the connectors and the rear case. I'm still getting horrible multitouch issues.
[Nexus 7 (2013) General] bladebarrier:
For me, it seems more like a case issue.

I don't seem to have any problems when not using a case, but when I do (which is most of the time) I have to pick it up and use my right hand. It instantly works when I do that. When I don't use a case, I don't seem to have any issues. I'm guessing my case is squeezing the screen and making it think there's a detected touch.

Either way, I'll probably just swap back to my old case, which has no problems with touch.
[Nexus 7 (2013) General] frozst:
Same here, opened the case and put some tape and I have a new nexus 7
[Nexus 7 (2013) General] Henrock11:
Where exactly did you seat the tape? Have a picture that may help in showing what you mean please? Thanks.

[Nexus 7 (2013) General] dickda1:
This is the fix to use. Have been using foam pads placed as shown (as of 8 months ago) and it totally fixed my touchscreen problem. Am skeptical about software fixes on this issue
[Nexus 7 (2013) General] Donkey2k13:
Dont buy n7

I bought it from walmart new 64gb coz of its slim size as compared to ipad mini. Lets start with BIG MISTAKE! it was my first time buying anything from asus. I had the unresponsive screen issue. I sent it back just before when the warranty was about to end. they repaired it and sent it back to me. had the same frozen screen problem. guess what they didn't fix anything! so got busy with the school work and sent it back after few months when the warranty was over. they charged me $200 for the screen + labor + shipping. what the heck? my screen was frozen when it was moved from place to place. now out of curiosity i came upon this thread and found that i might had the same problem with the screen coz there was something loose inside which was why the screen was freezing from moving. I am going to try this and hopefully it will work out. I wish i had read this thread in 2013. ASUS support sucks! if it is not going to fix, I will just give up!:(
[Nexus 7 (2013) General] lmacmil:
I only have issues right after I boot up. For the first 5-10 minutes it's very sluggish and non-responsive. After that it seems OK. Is that unusual? Running the latest stock lollipop version, unrooted.
[Nexus 7 (2013) General] Nproof240:
Hi all!!! After updating to lollipop my Nexus 7 had borring problem with screen. He don t like to rotate. If I reboot he is rotating a few minutes normal and after that the same thing. I was thinking with the last updates it will be fixed but it s not. Any solution?
[Nexus 7 (2013) General] mdamaged:
Try a factory reset.
[Nexus 7 (2013) General] Nproof240:
I tried twice... Nothing changed...:/
[Nexus 7 (2013) General] mdamaged:
Then I presume it's hardware, try this: https://www.youtube.com/watch?v=LLCAeBe2hVU, it also shows you an app to verify if it's hardware or not.
[Nexus 7 (2013) General] leercm:
It's fixed!

This post was started a few years back and I must say, it is still of great value!

The touch screen issue was bothering me for quite a while (since not long after I bought it early 2014). I finally could not stand it anymore and did a search. I found this post, followed the steps to open the back cover, try putting pressure to the connectors without unseating them, tape a piece of paper over the connectors (right where the foam pads are on the cover) to increase the pressure. And the result is good. No more phantom touch points.
[Nexus 7 (2013) General] jshamlet:
Will re-iterate - do this BEFORE screwing with firmware or doing a factory reset. Asus really screwed up on the ribbon cable connectors for these devices.
[Nexus 7 (2013) General] dickda1:
Totally agree. This is almost certainly a loose connector issue rather than software. Take a look at the posted video - it works
[Nexus 7 (2013) General] kmoffat:
My unresponsive screen was fixed by pressing on the center of the back of the tablet. I heard a small pop and the screen was fixed. I think the connector had become dislodged.
[Nexus 7 (2013) General] isorop:
Solved

I have installed android 6.0 (M) and the issue was solved. Please confirm that this issue gets solved with the latest android version. Update and tell me your result. Thanks.
[Nexus 7 (2013) General] bgorrell:
6.0 (M) did not solve it on my tablet. All connections are tight and pulled/re-seated for good measure. I'm working my way through the tsxx boot files one at a time now. So far TS10, 20, 30, 11, and 12 have not solved it. Each had their own different area of the screen that did not quite work (to varying degrees). I'm going to try the others.
[Nexus 7 (2013) General] FalconFour:
I've got a similar problem with my N7-2013, now running 6.0.1 but started off running 4.4 (when I got it "used"), then immediately updated to 5.x, then 6 on the day it was available. Since I got it, I've had the same problem - and taking the back off to re-seat the connector has had no effect (though I may try again if I can identify which one is the display, which is the touch panel).

My symptom is that there seems to be 4 equal quadrants of "touch zones" on the display, but they do not overlap, thus there are ~1/4" dead zones between the 4 areas. If I tap-drag across one of the areas, it drops the tap as I cross the dead zone, picking up as a new "tap-drag" on the other side. It's most noticable and easily verified on the home screens - if I drag across the screen, it "jerks" as I cross the center of the screen, both in portrait and landscape modes.

In games, this manifests in some REALLY bad behavior - since many games register "drops" as completing a desired action, and I didn't actually let go! Sometimes it'll pick up another element after dropping one in an undesired place. Obviously I'm not even talking about multi-touch here, either... just single motions!

I might need to buy a new screen, even though mine isn't even broken - yikes!

update: Well, now that I've stopped to dig into it and test it more vigorously, I don't know what happened, but it seems to have stopped doing it. :confused: I was moving my finger slowly across the exact center of the screen, and it revealed a "dead zone" as expected - but as I kept testing it (to see if I could start a tap there and not have it register at all), it started registering the dead-center tap reliably. Afterward, no matter how I rotated or swiped, it no longer had the "dead zone". At least for now. Huh?! Maybe a combination of re-seating the plug and tapping in the center like that... :confused: :good:

update again: nope, it's back again after sleeping for just 1 minute while writing that. Oh well. But it does seem to try to compensate for it...
[Nexus 7 (2013) General] ToastyZ71:
It's not always the ribbon cable. I have two Nexus 7 2013 tablets, one is fine, the other is nearly unusable. - phantom touches, not recognizing real touches consistently, can't swipe or slide. I swapped ribbon cables between the tablets, no change at all. Swapped the lower/daughter board that contains the touch screen controller chip, and the problem follows, so there could be a bum touchscreen controller chip or perhaps a bad solder on it. Wonder if an oven reflow would help
[Nexus 7 (2013) General] bg260:
Have you tried ParrotMod? Worked wonders for me.
[Nexus 7 (2013) General] Axel85:
You have all to try parrot mod, for me it works great. Never had many problems with one finger, even over a pillow, but with 2 or more fingers ghost touches start till I turn of and back on the screen. I tried everything in my knowledge inside, it must be the controller of the touch, maybe some nexus 7 are more sensible than others. I m a computer / electronic technician and I always have some problems with elan touchpad. For me the only 90% reliable brand when you talk about touch devices is synaptic ; elan Alps ecc all produce faulty / semifaulty drivers , and sometimes if you force synaptics driver on those devices they start to work perfectly ( you can t do it all the times due to the hardware model)

Parrot mode fake the tablet like if it s connected through HDMI to a TV via slimport. In this mode the driver change something in the touch controller that make it work at least better . You can read about it in the response the developer of parrot mode gave to me in the related thread.

To make the story short, now with parrot mod I can reach 10 fingers even over a pillow, without any problem, and without the touch registering any ghost touch never.

Now I have a perfect tablet,yesterday I used it for 5 hours
[Nexus 7 (2013) General] CYoung234:
Thanks to all in this thread. My Nexus 7 2013 has worked perfectly until recently, when it really started acting up for single touch, particularly in landscape mode. I have a bookreader app that I highlight text with, and it was awful, where it used to work perfectly. I am using Parrot mod as well. I ended up taking the tablet apart yesterday and removing and reseating the connector. It is now working perfectly again. I had tried different ROMs and had even taken it back to stock software with no improvement.
[Nexus 7 (2013) General] gfunkzero:
Hey guys

Ironically I opened my N7 to re-seat the cable and even just using my bare hands managed to crack the screen AND digitizer

Ive now replaced the screen and digitizer with a cheapie off ebay and about 3/4 of the touch screen works now, the top and left edge areas don't work!!!

its a different issue to what i had originally which was just phantom presses, do you think its a dodgy digitizer, i need a new cable or maybe Ive just installed the digitizer wrong? personally i thought i did a really good job, ive opened it and tried reconnecting the cables

again its just the top and left edges that dont register touch
[Nexus 7 (2013) General] fuzzie:
gfunkzero I did the exact same thing, which changing the battery...small crack in the middle left side. Got battery in, worked, but the screen is not responsive. Some parts on the right side work, but not as expected. Even when not touched, some apps start and changes are being made, like volume up or down, screen brightness, etc.

I've tried reseating the cables (both) several times. I'll try the taped down fix, with a little piece of cardboard. BTW, mine is mounted in my car as my head unit. So it isn't being held or in a case (although I have the same problems when it's out of the car during testing). I'm at a lost...I'll have to buy another one because I love the car install. Here's a video of the install:

https://youtu.be/CjpAQHARNO0

I'm not looking forward to rooting, unlocking, installing Timur's kernel, and getting this install working as it was. But alas, I learned my lesson...need to be careful when taking this apart.

I was looking online for a new screen, thinking that might solve the problem. Not sure it is worth it, though.

Sadly, I use the WiFi + 4G model, which is much more than just a WiFi model...ugh.
[Nexus 7 (2013) General] fuzzie:
I ordered a Google Nexus 7 (2013) LCD and Touch Screen Assembly Replacement

from https://www.fixez.com. Got here in two days, and after a couple of hours of adding money to swear jar, I was able to replace the screen. Everything works as before and the N7 is back in the car, working like a champ!
[Nexus 7 (2013) General] gfunkzero:
Good to hear you got it going again, I ordered another screen to try again with just haven't bothered yet but fingers crossed
[Nexus 7 (2013) General] fuzzie:
It was a serious ***** to get the broken screen off. I had glass everywhere. But after I got it off, it was fairly pain free. Be very careful with the volume ribbon. Watch a YouTube video on taking it apart, several times.
[Nexus 7 (2013) General] ojcu:
I had an issue with touch occasionally not working and rotation not working at all. In the beginning simple reboot was helping, then disabling Google news feed, then I found some tutorial on YouTube to push ribbon cable connectors and it did the trick for a while. But then it stopped... With rotation it was easy, just to install proper app. But the touch? That was really annoying when I couldn't swipe to unlock. Few days ago new idea came to my mind. I opened the back, disconnected the ribbon cable and sprayed both female and male connectors with electrical contact cleaner spray. Left it to dry, connected everything, turn Nexus back on and then the magic worked - my tablet is rotating and responsive like brand new. Hope that will help you guys.?
[Nexus 7 (2013) General] bokoy:
You know it would help a lot of people, please try it. Well also the pictures would be great, more than perfect.

Mine is going to asus for second time, if they don´t fix it I´ll try this for sure.

Thanks for everything

Ed: The touch screen cable is the gold/amber flat cable, isn´t it? And the other white/silver flat and bigger is usb+speaker? We are interested in the connection bettewen the motherboard and this gold/amber cable on the top of the device, or in the one in the bottom near the usb?
[Nexus 7 (2013) General] shams6:
Try to give a clear shot we are noob here.
[Nexus 7 (2013) General] bokoy:
I didn't open it yet, just watching zedomax disassembly video, you can see everything clear.

http://www.youtube.com/watch?v=BUT6bZdITo8

Min. 6:09 he begins with the cable we are interested in.

Min. 6:40 goes exactly to the point, I guess, where the problem is.

Min. 6:50 he even say it has the tape to hold it in place because in too loose. [MENTION=372570]GSLEON3[/MENTION] can you confirm my guessings.
[Nexus 7 (2013) General] Tim4:
Today i were playing on my elec guitar and i noticed some strange interference noise...

To be short - nexus7 screen generates very, very strong interference on elec. guitar pickups when located close enough. Removing back cover doesnt change anything. It generates interference even with screen turned off (I using tap2wake though), much lesser, but still.

And i tested my LG phone as well - very low interference with screen on, and none with screen off.

So pretty much the problem is related to grounding (In my case)

Or low quality parts. Or board design failure :(

p.s. oh nice, gonna check out the cable.right now

p.s.s. No luck my cable not loosen even a little bit
[Nexus 7 (2013) General] yelloeye:
I'll have to check mine. Mine sometimes "sticks" when spots are pressed.

Anxiously awaiting a how to and list of materials used.
[Nexus 7 (2013) General] Tim4:
By the way guys, im typing this text as i noticed that all my touch bugs gone. So im typing this large text to check if the bugs still here and as u can see it seems all fine. Thats just a mystery, did checking the ribbon cable really helped me? Or its all the stars? No even a single issue now, unbelievable.

And the bugs i had - not the multitiuch but often freezes, ghost touches, quad touches and etc. Typing on keyboard was annoying as hell since it always looked like "Hi guuuuuyyyyyys wjets upppppp" and now its fine. How. Wow. Incredible

Still cant believe the bug gone, so ill type more. God bless the op who suggested to check the ribbon cable.
[Nexus 7 (2013) General] bokoy:
I can tell you that for me is also really odd. When I do a factory reset it runs great for two or three days, not one single issue, but after that everything begins again. Multitouch doesn't work at all not even with two fingers playing dead trigger 2, is just insane loosing one or both fingers and selecting items and buttons all around the screen. The super lag also happens to me with freezes like 15 to 20 seconds. Is just disgusting, I love this machine but this problem is so big and frustrating...
[Nexus 7 (2013) General] Matrix_19:
Freezes and ghost touches were fixed (for most ppl) with kitkat, are you on 4.4 ?
[Nexus 7 (2013) General] Tim4:
No, i was on 4.4 just for few days after the release and reverted back to CM10.2 + faux 007m
[Nexus 7 (2013) General] shams6:
Me also revert back to 4. 3

Btw will this solve my random reboot issue...

My problem is suddenly freeze my screen then reboot. Sometimes three or four reboot in a single reboot. The problem started when 1st time i open my tab. Then still it persist, i have used many custom rom, orginal image file but still problem persist. I can't send it to rma as i am out of usa :'(
[Nexus 7 (2013) General] Luigi_2:
This really saved me :) big thank you
[Nexus 7 (2013) General] garibarba:
Don't know which cable

I'm having touchscreen issues and I've tried what OP proposed. I tried to push the connections but none clicked. I'm not sure of which connection to push.

The issues are still here. However, I'm finding some correlation between this issues and my case being on. It might be the case doing something wrong or my hand doing some good by applying pressure on the back when it is not in the case.

My case has magnets.
[Nexus 7 (2013) General] Anderson2:
Fwiw, I have long noticed a correlation and wrote about it on this forum.

I use my nexus 7 with the case folded back 180°. I noticed that when the touch screen freezes, if I lift the folded front cover 10° or so off the back, the freezing immediately stops. At first I thought it might have to do with the magnet too close to the back of the tablet but it might be pressure.

The other possibility is that the cpu is busy with some other task in the background causing the problem. I wish there was a way to know what is running in the background at a specific moment. Task killers do not give the full story of all the processes running.

Either way it is annoying and I wish Asus would fix it! Never happened with my 2012 nexus 7. The 2013 nexus definitely has quality control issues. I wish Google or Asus would behave like MS which is replacing its defective Xbox 1 units.
[Nexus 7 (2013) General] animania260:
Just finished this 10 minute little fix that, so far, has completely fixed all of the touch issues for me. I can actually use the device when I'm not holding it now!!!

So I just wanted to say thank you very, very much for this post. I highly recommend this quick easy, and very simple fix to ANYONE having touch issues. Its so easy, no tools required, just pop off the back, and simply push down on the golden/orange ribbon at where the top of the device would be. Just make sure the connector there is completely flat. Or you can simply pop up the connector and reconnect to get that nice, confirming click sound and satisfaction knowing your touch issues are completely resolved now! ????

Seriously, thank you again for trying this on your device, confirming and writing this post for the rest of us. It is greatly appreciated, and I think this should be labeled as "the" fix for any and all touchscreen issues, because no software update/fix can cure a loose connection, for those that have this issue.

The touch issue was the one thing that kept me from completely loving this device, and now everything is perfect- for me anyway, as it should be!!

Thank you!

Happy Turkey day
[Nexus 7 (2013) General] furou:
There are two cables running across the battery, a silver and a gold one. Is it confirmed that the display ribbon cable I should try securing is the gold cable?
[Nexus 7 (2013) General] animania260:
Yep it's the gold one.
[Nexus 7 (2013) General] Sensamic:
OP, please post pictures of the process step by step.

It would be great for non-english users like me.
[Nexus 7 (2013) General] heorung:
Pls post a video guide. Thanks OP.
[Nexus 7 (2013) General] oddsocks:
Thanks op. Just resat the screen connect and the screen is working quite well. I wasn't quite sure how you reinforced it so will be waiting for that tutorial. I'm surprised that Google and Asus released the tablet with these hardware problems.
[Nexus 7 (2013) General] furou:
Checked the cable and it seemed secure so I disconnected it and pushed it back in. I noticed that when pushed, one side will always have a satisfying click while the other doesn't and just kind of falls into place, however it doesn't feel loose if I tug on the ribbon cable. What is others' experience? I'm wondering if getting no click on the other side means I should use some kind of adhesive to make sure everything is connected properly. It's just that the touchscreen isn't completely cured. However it would occasionally go crazy and so far that hasn't happened so I am seeing an improvement.

Also, if I'm already sticking my hands in the nexus internals, is there anything I can do to fix slight light bleed coming out the right side as a blue and yellow light? Maybe loosen a screw somewhere?
[Nexus 7 (2013) General] Matrix_19:
Opened it and everything was fine... But I didn't try to reconnect it
