I dunno if this makes any sense at all.. but changing tap and hold delay from short to medium seems to be working on fixing my stylus issue o_O?

oh and I opened it up again and a few adjustments to make sure the foil is now touching the metal casing around the battery and I taped it down too. Even if its not a 100% fix it's SO MUCH better than before :D

Tape

It is actually sticky foil tape used for sealing air conditioning ducts.

quick question:

the stuff listed on that thread, would doing that help me? or does this foil fix get the job done?
[Nexus 7 (2013) General] Gorgtech:
Let me ask you a question : Let´s say that you have a accident and break your arm, what would you do now ?

a) try different painkillers to see which one might help you to not feel that you have a broken arm and suffer pain

b) go to a doctor and have him fix your arm ?

Chose for yourself, like I said before, flashing some other Firmware and hoping for a fix which cannot be managed through software only is not the right solution to solve a problem, at least this is how I look at things like this when it comes to "try and error" ..
[Nexus 7 (2013) General] jinyung2:
that's a good analogy, my "arm" is very healthy now I don't think it needs fixing :)
[Nexus 7 (2013) General] player911:
Well I disagree about not flashing a firmware fix. I did this method and it helped but I still have spot that are finicky and require several taps to register. I have on "show screen touches". I never had random touches but some parts were not as responsive as others. Flashing the touchscreen fixes helped that tremendously.

I think this method helped some, but I still have issues with random missed keys or touches. What I did, was slide a piece of foil under the cable. This piece was about the size of the battery. Next I cut a smaller piece to cover the cable with a little extra on the sides then taped it down.

I tried following the OP to the letter but it resulted in no screen. So after several attempts, I ended up removing everything, booting into android, and doing 1 step (my way) at a time... testing the screen as I went. I am a network engineer and checked each connection multiple times.

Anyway, don't knock the firmware flash. It really works great. I think between the 2, this is the best it will ever be. I doubt I can still play a FPS or any action game. While it is WAY better then before, my axis get crossed and stuck and go haywire too often to be enjoyable.
[Nexus 7 (2013) General] threi_:
Tried flashing a different touchscreen firmware which did work slightly better but still had some issues when i wasn't holding the tablet, so i went back to stock and tried this mod...

Wow, what a complete improvement. Actually works flawlessly now.

Silly me for continually underestemating ASUS' competence in making good hardware. They always find a way to dissapoint me.

Anyways thanks for the tip OP, and the analogy made earlier is spot on.
[Nexus 7 (2013) General] kicsrules:
ok right now is too early to say its working, i haven't fully tested the tablet but i think it has been solved with this mod, first i tried this method http://xdaforums.com/showthread.php?t=2428133 then i had some improvement... but still it didnt work 100%, now i think it works 99%+ because i havent seen any ghost touches (its only been one day since i did this)...

1) applied this mod, only on the strip that goes across the battery (not the whole battery)

2) removed any custom images (keyboard images) from the tablet: applied boot-ts-unlock.img from the thread mentioned.

3) re-installed firmware 5.1.1 from google https://developers.google.com/android/nexus/images

4) waited for the device to reboot and then locked the bootloader again

5) tested, everything working ok/ fully functional... will report within a week
[Nexus 7 (2013) General] idCyber:
Thank you ! I fixed my N7 2013 ! I wrapped one layer of aluminium foil around each cable and placed folded pieces of paper on top of the connectors and now I can use my tablet when not holding in. Before, while I had my N7 2013 on the table , the touch screen was not responding at all. Also sometimes I had problems with autorotation, hope this was fixed also. Today, after I did the fix I have used my tablet for a couple of hours and I haven't picked it up. Right now I am typing by having it flat on the table. Thanks once again !
[Nexus 7 (2013) General] Gorgtech:
I´m glad this MOD did the trick and helped you too ;)
[Nexus 7 (2013) General] brombadeg:
happy now

Gorgtech! I've decided to apply some grounding after 2 years of use and one replacement from Google that didn't help.. :mad: I was thinking to do some grounding cabling when I luckily found your MOD. I'm really glad for your share and I'm looking forward who it works after do it today. :)

I'm also concerned about the audio quality. This piece of device is a **** compared to my previous iPhone products not only the quality, but also the noise you mentioned! At least as I read for the noise can be solved. I'm a bit reluctant how it has to be applied and I wonder if you can explain it a bit more detailed.:rolleyes: You actually wired it around with silver at the back of the housing bypassing the internal connection of the two side (top-bottom) of the device?

Someone else has done it?
[Nexus 7 (2013) General] Gorgtech:
Exactly, I bypassed 2 connections with conductive silver ink but in order for the MOD to work, one of the 2 connections needs a extra conductive pad or else it won´t be connected through the silver trace.

Basically you can achieve the same results with a thin wire and a soldering iron + some solder.

But I guess the main reason why the noise vanished is due to the shielding from the data lines. The Nexus 7 ( 2013 ) has some poor electrical design :rolleyes:
[Nexus 7 (2013) General] brombadeg:
So far so good! Shielded the two cables and the screens seems to be more responsive. Time will tell if it works. but the audio still creepy, so probably have to do the silver stuff
[Nexus 7 (2013) General] ct85msi:
I attached the conductive pad on top of the aluminium foil, not on the touchscreen cable. Is it ok? Touchscreen performance improved a lot, actually I don`t have any glitches. Before, the glitches were more visible when opening and closing new tabs in chrome, on the top portion of the screen.

I also introduced a strip of cardboard under the touchscreen cable to keep the cable pressed when the rear cover is mounted. I guess the back cover presses the aluminium foil onto the open copper spots so that the circuit is ok. (copper cable - aluminium foil - conductive pad)
[Nexus 7 (2013) General] Gorgtech:
It´s ok, the extra pressure ensures a tight contact ;)
[Nexus 7 (2013) General] HyBReDM:
I'm about to take on both these mods because the audio buzzing is driving me crazy, I have it hooked up to my cars speaker system. I'm not entirely sure where you put the conductive pads though?
[Nexus 7 (2013) General] arolust:
Just did this mod to my tablet, I found it had horrible ghosting, I constantly had to turn the screen off then on again and HOPE that the problem areas where out of my way for the moment. (and I have tried all the different TS, settled on ts10).

So far no problems, keyboard works perfect, and games no longer have the dead spots (joystick controls make it easy to spot).

Thanks.
[Nexus 7 (2013) General] janbertwafu:
I rarely comment here on xda. but man, this helped my haywire touchscreen like a lot. will try to apply ts unlock and revert to factory images. will report in a week :) Danke Schon!
[Nexus 7 (2013) General] tehabe:
The dangers of trying those fixes, you might ruining your device. Well, on the plus side the losing contact to the touchscreen and ghosttouches are happening less now. They are not gone though, maybe my tinfoil is too thin or simply the worst I could have used for this. Putting anything below it made it worse again.

The only thing I really ruined is the little tape which goes from the mainboard shielding over the connector of the cable to the cable. (Btw. I wonder why the shielding of the main board has a copper tape on top.). I just hope this little tape was just to hold the connector into place and no other purpose, if this is the case it is easier to replace.

But anyway, it already helped me a little and without costing me too much of the precision I lost when I tried those driver patches.

Update: I redid the hole thing but I have still a lot of ghosttouches and contact losses when I move over the touchscreen. I might did something wrong but I can't check this :(
[Nexus 7 (2013) General] SpecialBrewDaddy:
Tried shielding the screen ribbon just like what you did. First, my N7 screen was unusable. I'm stuck at the choose your language/country. Once I read this, I did shield the sable with aluminum foil, but with no positive result. Then I've used wired mouse via sub OTG just to get inside android and open sub debugging mode. Flashed the first screen firmware which is the ts10 (sorry for mentioning other method). Now my screen is usable again but with a little horizontal dead spots at the bottom (portrait orientation). Before I tried the firmware but whenever I use 2 fingers, problem will occur again. Now, I think grounding issues were solved because of the shielding. Thanks! I can now enjoy my N7 2013 again.
[Nexus 7 (2013) General] SpecialBrewDaddy:
Can I also use aluminum tape for shielding guitars?
[Nexus 7 (2013) General] mwrobe1:
I have followed this thread from the beginning and always thought of what kind of touchscreen problems others were having. My device has not experienced any of the more serious issues described and I have not popped open the device to try the mod.

That being said, its been a week or so since Android M and it feels like touchscreen response is marginally better now. Has anyone else experienced this or is it the placebo effect?

Is there a newer hardware revision of the N7 without these grounding issues?
[Nexus 7 (2013) General] cloves:
I hate having my tablet in my window holder and touching a button and it not registering all the time. If I put my finger on the tablet and then touch it always registers which is a grounding issue. But maybe its just a ram issue. Reason I am saying this is because I use an app to free up memory like droid optimzer, bang all of sudden all my touches register! I feel its a grounding issue but maybe its a memory issue as well??

Nexus is working fine for me when I have multi ROM(cynogen and aokp)
[Nexus 7 (2013) General] Axel85:
Maybe I found a shielding method that make the touch almost perfect. I will post if this continue to work for some day. It s only a little variation to those posted, and involve only aluminium tape (mine bought at a Chinese market for 3 euros) . My touch was almost usable before, but not perfect. I could see it when I scrolled pages or tried to close chrome tabs,or write with the tab on a surface.Almost the time my touch worked OK with one finger even over a table or a pillow, but started to give problems with 2 fingers after some minutes or less if used 3 or more fingers till I turn of and back on the display. I tried touch firmwares but with no luckand many of your hardware fixes. So I started testing... I m a computer/smartphone repair technician, and I sold a perfectly working fonepad 8 ,but slow even with a decrapified os to buy a nexus 7 2013 used , without knowing of the touch issue. The old fonepad touch was great,and screen too, but the tablet with the lollipop upgrade gone sh*t. I decided to go for a nexus, I love them ( I have all the product from them ) ,the user experience for ROM and modding is incomparable wit other devices. So making the the story short, I found the problem (defect) when I received the table. I spent the last 3 days trying to find a solution, and tried many shielding method,even with the tablet turned on to make it work good or die forever. Whit this new shielding now I could write this post without a problem,over my bed , chrome tabs or small buttons cliks perfect,and scroll is super smooth. Up to 3 fingers the touch never fail even over a surface, and if I try 4 or 5, now I don t need to turn off the screen and back on to make it work normally
[Nexus 7 (2013) General] k23m:
Impossible

But the cable you are shielding has nothing to do with touch screen whatsoever - it is only, exclusively, the LCD drive cable. Any alleged interference on this particular cable might only distort the picture but not the touch function.

Touch control takes a completely different path:

touch screen connectors and cables

ELAN - touch control chip

ELAN's processed touch with other signals connecting to main CPU

I am sorry if I am repeating this observation but this thread is so long and I only read the front page.
[Nexus 7 (2013) General] tehabe:
I tried this for a while but my issues never really got away, through a friend I got hold of another Nexus 7 unit, but it had a defect screen. I basically switched everything out, main board, daughter board and the both cable between them. And it occurred to me, that below the daughter board is the digitizer of the display. It is covered with some protective tape but maybe I could solve the remaining ghost touches and non-responsiveness in the top third that I'm having by reinforcing this shielding.

You can see the part I mean in the attached photo.
[Nexus 7 (2013) General] Deeco7:
Does this method actually fix the issue? I've seen another fix on xda, can't find it...
[Nexus 7 (2013) General] k23m:
It can not fix the issue, it can only create another one. Perhaps you could ask the OP, but he is very busy designing similar innovations for other devices and completely ignores this thread.
[Nexus 7 (2013) General] XFreak44:
I get a lot of buzzing from the audio jack and buzzing when I touch the screen while the device is charging. Will the aluminum foil mod fix the problem or will I have to do both? I dont quite understand how the second mod works where you put sliver traces down. Can someone please explain that to me.
[Nexus 7 (2013) General] Axel85:
I already tried to solve ghost touches in many ways... Tried shielding over cables,tried to clean connectors with isopropyl alcohol, tried to add or remove ground connection between cables ,shell, isolate battery, isolate shell, solder grounding points,improve grounding with copper mesh,disassemblee the whole lcd and replace the adhesive tape...but nothing seems to improve the touch. I give up, this touch has some engineering problems,maybe it s related to the poor quality controller. I m an hardware and computer technician,and I had many devices with similar problems. Sometimes there are some computer touchpad that are unresponsive the same way, me and a friend had an Acer notebook with an Alps touchpad . All the two devices were very unresponsive, we sent them back to Acer 3 times but they said they were working like normal. I can only say that from my experience,the only touch devices that works good are the ones made by synaptics,I don't trust anymore any other brand,I have to fight almost everyday with elantech,alps,and sentellic touch devices that sometimes works like sh*** .Sometimes is only a matter of bad manufacturer s drivers. My girlfriend has a new lenovo notebook, with sentellic touchpad, I tried everything to make the scroll work with two fingers (believe me I tried everything for almost 10 hours of work because in 2016 is ridiculous that this feature is not working n a new pc). Then I found someone in a forum with a similar problem with another touchpad,were he said to disable driver signature enforcement, and force synaptics driver,because sentellic touchpad are very similar to some synaptics models. I tried because I was thinking of return the laptop,and guess what??? It s. Working and now everything is more responsive and fluid. Electronics producers no more test devices for long time before release... We are they're beta tester, sad story
[Nexus 7 (2013) General] tehabe:
I'm actually still amazed how well the touchpad of my 2009 MacBook Pro is. No idea where Apple gets their touchpads but it is very well made and reliable. I had an Elan touchpad on my Asus eeePC 1000H, which worked well enough.

Btw, I shielded the white cable with tin foil now, and so far all good. Except for the losing touch in the upper third or fourth of the screen. Which is fixed by turn off and on the screen. Annoying but not that annoying I think.
[Nexus 7 (2013) General] k23m:
Have you tried different touch panels with the I/O PCB? If so, please post your observations in this thread.
[Nexus 7 (2013) General] Axel85:
No, never. But I suspect that the old owner changed the display. I can tell you almost for sure because when I opened it ,I found the seal over the screws broken,and some fingerprints over the copper foil. More than this the display was not perfectly mounted,and higher than frame on the left side. Nothing that I made,changed the initial situation,I wrote here in the forum I found a solution,but was not true ,because I had the same problems 10 minutes after I wrote the post. If I use one or two fingers the touch is perfect in all the screen,over a pillow,a table,doesn't matter, but when I start using more then 3 it start to register ghost touches even with one till I switch off the screen and back on. I give up,because i think I m lucky,at least mine is perfectly usable,but if you need some help you have only to ask

The only thing I would like to fix on mine is make the finger area of a touch bigger, because when I try to close a chrome tab,sometimes it s not very easy, in my nexus 5 is far more easy to push on a small object

[Nexus 7 (2013) General] abemore:
I previously tested grounding the N7 by laying it on different materials:

https://xdaforums.com/showthread.php?p=56898816#post56898816

In those tests, aluminum foil failed to be a good ground (even layered several times).

But I read it works well as EM shielding, so I decided to give this mod a shot. I even added some weather stripping to secure a section of loose conductive tape. And I wrapped the second ribbon cable for good measure.

So after 5 minutes of testing...

This mod does NOTHING.

The touch screen issues remained EXACTLY the same - UNCHANGED - as confirmed in the Multitouch Test app with the tablet lying flat on the desk.

Mod removed.
[Nexus 7 (2013) General] k23m:
Actually this mod can do SOMETHING but not what you expected.
[Nexus 7 (2013) General] abemore:
well... I only tested the OP's first mod - the supposed touchscreen fix.

If [MENTION=4827892]Gorgtech[/MENTION] really did fix the touchscreen issue, then he did so with his second grounding mod. The one to eliminate headphone jack noise.

---------- Post added at 12:57 AM ---------- Previous post was at 12:15 AM ----------

Nope.

Just tested the second mod by fashioning a wire out of aluminum foil to connect the large copper area to the metal frame of the micro usb port (just as OP did with conductive ink).

Touchscreen still fails to multitouch properly.

Both mods are a waste of time
