[T-Mobile Samsung Galaxy S 4] InsomniacoreDSPS:
The step by step details of what I did are a couple posts back (I tried online suggestions like removing my google account from my phone, reverting the app store back to the stock version, re-adding the google account, then rebooting, and then my phone stopped working).

After that I tried a couple of the apps on the google play store that are supposed to be 1 click fixes for the google play store update error. That was my mistake. A lot of people had success with those 1 click fixes, but thats what I believe bricked my phone. I would tell you which app specifically but I can't access my phone (obviously) and they won't come up on the PC version of Google Play search.

Thank you for your desire to help. Is there any other method of communication we could use that might be more efficient for me to be able to answer your questions? IM or fbook chat or something?

Revert to stock : Complete

Hate that I lost everything, but I shoulda been more responsible with backup in the first place. I am with my computers, typically am with my phone, but I was foolish enough to wait until I could get a great deal on a high capacity micro SD card...silly silly me.

Hello all I am still running the stock ROM except rooted with G2 Xposed installed. However I hate having the stock boot image on the ROM does anyone know where I can get a different boot image? Also how would I go about loading the boot image? I know in /system/media there is "bootanimation.zip" could I just get a boot zip file and replace or would I actually have to flash the boot?

[Nexus 7 (2013) General] marcus2004:
Thanks for the post! If I know the issue I don't mind taking it apart to fix it.

I RMA'd it once as I didn't feel I should have to fix it, but it was such a pain jumping through all the hoops only to get it back with docs stating "OS reset" and finding the problem 30secs after resetting up my account.

I have another RMA but have waited shipping it for an update to KitKat in the hopes that it would help. It hasn't. I'll have to see if I feel up to trying your fix.

Thanks!

Video tuto

Need a video tutorial. I have both touch and multi reboot issue. sometimes there are 2-4 reboots occur during rebooting of system. problems persist even after kitkat update. I think this is the cause that causing me such multireboot issue.

Hope this will solve my problem. i am out of USA country so i cant give for a RMA. But need a solution look like that.
[Nexus 7 (2013) General] Anderson2:
Thanks gsleon3. It always sounded like a hardware bad connection type of issue so I'm not surprised.

The problem with rma is that I'm not sure their repair techs would really fix anything. The cause may not have been made known even to their own techs because it would leak out and might start a class action law suit. My 2012 nexus 7 never had any of the touch issues my 2013 version is showing. Quality control has slipped with the 2013 version.

Any lawyers here?

nearly an inch long strip at the top of my screen stopped responding to touch i sent it back only had it for 6 days..
[Nexus 7 (2013) General] unibomber:
Tried this out. My clips were seated properly but I can see the reasons why they pop out.

Took about 5 mins from start to finish to test. Good job.
[Nexus 7 (2013) General] ibebyi:
OP, during your disassembly of the device did you notice any random internal parts that could possibly be applying pressure to the screen from behind it? I ask because my otherwise perfect nexus 7 got a random blue dot in the middle of the screen and I know from past experience that that's typically the result of pressure physically warping the lcd panel.. otherwise the only other thing I can think of is that the lcd is being permanently damaged by the on/off case magnet but that's unlikely. or maybe heat that's causing the battery to flex into the screen. It's extra frustrating because I've had the nexus in a loose fitting hard case and the hard front flap should prevent the kind of pressure damage that would cause those blue marks... sigh.
[Nexus 7 (2013) General] sfhub:
Well if it is pressure, I've found on past devices, sometimes batteries start expanding over time, like they have a fat belly.
[Nexus 7 (2013) General] LittleConfucy:
Touchscreen possible fix

Started reading a bit on Google Products Forum and found a guy who said that the touchscreen problem can't be fixed by software.

So he took the back of the tablet off and found that the problem lies on the screen digitizer cable not being clipped to the connection port correctly. He disconnected the cable and connected it back again, and now his touchscreen is working perfectly.

I do not want to try it because I don't want to risk anything, but can anyone brave enough try this?:fingers-crossed:

Here's the guy's profile: http://productforums.google.com/for...ioWy9HdPwsowoDCuOz8SS9uR9nzVnPi6g2kSAInwwCj94 (it's the post form Nov 19)

Ive disassembled the device too and it has nothing specials with exception that few flex cables located right unddr the cover. Not sure if one of them is belongs to touchscreen though

Sound really greate and promising. If you could, a tutorial video would be perfect for us, please :)
[Nexus 7 (2013) General] i486:
If higher amperage is used there is an increased risk of expansion due to the higher excitation in the Li atoms. You will increase the wear of it too.

So if possible always use lower amperages to charge batteries(preferably around 500mA), you can limit the charging IC using a lower output charger or your computer's USB port.

Isn't that what sfhubs touchscreen firmware fixes are for?

http://xdaforums.com/showthread.php?t=2428133&page=140
[Nexus 7 (2013) General] graphdarnell:
My impression - and I could be wrong - is that the OP in that thread is not very keen on explaining why so many variants (what their sources are) and what they do exactly. I've noticed that on my tab, ghost touches would appear when I press one corner of the touchscreen down, even with the touchscreen ribbons unattached! I've used EMI tape to insulate areas I thought might cause ghost touches and the problem went away. But I experience some lagging and "grounding" issue still, not so much when the tab is laid flat down on a table, but acute when stood up in a case in certain positions.

So it's like sfhub said, hardware-software related problem. But one cannot begin to try sorting things out not knowing what does what. Of course, I try to fix my tab. But I'm sure my situation is not unique, and a solution for me might help other members with the same problem too.

Luckily, one member has combined all the firmwares into one package here, except it's not flashable yet in its current form. Guess will have to wait for some devs who care enough to integrate it into some custom kernel, an area in which I'm no expert.

PS: the OP suggests that the ribbons be taped down to the battery so they would be secured. Well, if I do that with my tab, unresponsiveness would turn permanent in some areas of the touchscreen. So find out what works best for you!
[Nexus 7 (2013) General] InfX:
Any idea if this calibration uses any kind of finite resource in one way or another, for example, some kind of EEPROM with a limited writes count? I don't want to eventually cause some damage, but would like to try & run this calibration every time the screen goes off, this would allow just hitting the power button if/when you encounter issues, turning it back on, and seeing if it helps.

Attaching a tasker profile and a tasker generated apk that does just that. Use at your own risk.
[Nexus 7 (2013) General] CTCaer:
I don't think so, also modern eerprom has 1million write life time.

But well I don't know if they keep it or using ram.

I will try this:

cat /proc/kmsg | grep "elan_ktf3k_ts_rough_calibrate"

This will check for a msg, "[elan] elan_ktf3k_ts_rough_calibrate: enter". This shows when the calibration starts (plus the other dump cmd message).

They drivers show that the device can start the calibration. So it seams timely. But we don't know how fast it does it.

Also change it to "screen on". The touchscreen goes in suspend mode when the screen is off.
[Nexus 7 (2013) General] InfX:
Are you sure it doesn't wake the touchscreen up? Or if its ever suspended at all? Note that the kmsg shows the (screen off) calibration succeeds. Also, there are some custom kernels that let you wake the device up buy double tapping the touchscreen, having no negative battery impact. Kinda implies in is never suspended. The reason i didn't do it on "screen on" is because it does take some 500+mS, maybe a second, one may already try & use it during that time.
[Nexus 7 (2013) General] CTCaer:
I wrote this because we don't know if the calibration is truly happening if it goes in suspend mode. I don't know. It maybe really happening.

Don't forget that I didn't ever saw a CMD_S_PKT (command send packet from touchscreen) that has 0x20 as a value. This value procs the process_resp_message function and in case of 0x20 it shows the rough calibration result ("Get the Rough Calibrate result:%d\n").

Also about wake up gestures, they don't let touchscreen to suspend, so no problem there, as for the impact of s2w to battery it's not big but it's there (well I have a smart case, so absolutely no need for me).
[Nexus 7 (2013) General] pixel-painter:
Fantastic! Worked immediately

OP Thank you so much for this :)

I have been having random problems with touch which became progressively worse until no touches were registered at all. Cover came off great, and while the ribbon appeared to be in place, I unplugged and replugged ribbon using a small plastic utensil.

It works great now, but do I not have any long term results.
[Nexus 7 (2013) General] LinearEquation:
If all the contacts are connected now then this may be your fix.
[Nexus 7 (2013) General] _delice_doluca_:
I never had any problems of ghost touches, unresponsiveness at anything expect the game Dead Trigger 2. Keyboard, multi touch etc. Was just fine. However very Dead Trigger 2 wasn't pulling the trigger sometimes even though I touched the button or sometimes my moving forward man would just start leaning sideways or going back or turning his head to somewhere else while shooting. It was very very rare (I couldn't even be sure there was a problem till I played the same game with my brother's Galaxy Tab Pro 8.4). But it was there and disturbing at times (especially when you get killed because of a missed shot). The presedure took less than10 mins and now I am enjoying the game.

Here is how and with what I did it;

First you need long fingernails like I did.

Put your fingernail to the left part of your tablet. Choose the upper half of it, slightly higher than the middle (considering you are holding the device facing at you and in a vertical way). That's the easiest and least risky part. Fingernails won't go in, instead the frame will separate itself from the housing approx. 0.5mm (that's 0.02 inch).. Now go up, once you reach to the corner don't continue. Instead now out your finger to the beginning point and go down this time. Now separate the left up corner and go to the right side from the top. Then open the right upper corner and very slowly slide down. Remember buttons are there so be careful.

Don't try to separate the bottom part, as its holding the USB port with a hole in the middle. Once 3 sides are open hold the upper part and move it like its a car hood. The housing and the screen will look like a huge V letter which is hold together from the bottom. Now carefully move the housing down so it can free itself from the USB port.

That's it, now you are ready. Here I used 2 beer bottoms as you can see on the photos. That's for preventing the screen touch to the wooden surface and preventing my hands touch to the open back of the tablet once I try it on my hands.

What I did is to lift the metal port with my fingernail. You don't have to take the tape out, actually you shouldn't even try or touch it. Just lift the metal frames and press them again. with your finger top (no nails here as they can apply high pressure on the covering like a knife). If you really wanna hear two "clicks" don't just press it, instead start from the left side (now tablet is not facing at you so you calculate what "left side" I am talking about) and insert there first, then the right side. Lower your head to the same level of the tablet to see if the jumper is leaning to the forward as its the highest possibility. You must make sure that its perfectly parrellel with the tablet. It shouldn't look like it's diving into the board. It should stay there as a flat surface. Then you are good to go.

Putting the housing back is not a "start from where you like" mission. You must first put the bottom into the housing. I suggest you start from the lower right corner (tablet is facing you now). Then make sure the left corner is also set and then you can press the rest of it.

Hope photos can help you understand more:)

it may be too soon to call it victory but this was the fastest fix i've done, thnx OP, i didnt notice any loose ribbon but still applied pressure to the connector, will report in a couple of days to post short term results
[Nexus 7 (2013) General] kicsrules:
well... this sux, the first time i did the fix, i did not close the bezel correctly and no had no problems at all, when i saw that it was closed incorrectly i opened it again and closed it.... now, i have ghost touches on the right side edge (portrait mode)....

:/
[Nexus 7 (2013) General] kicsrules:
ok i opened the tablet again, placed the gray ribbon with masking tape (it was not sticking correctly to the metal ribbon) apparently it has solved 99% of the ghost touches, now i have a ghost touch once throughout the day... i say its fixed....
[Nexus 7 (2013) General] graphdarnell:
What gray ribbon sticking to which metal ribbon? I see 2 ribbons running the length of the battery: one amber in color for the lcd, and the other metallic looking connecting the two PCBs. Which ones are you referring to?
[Nexus 7 (2013) General] kicsrules:
the gray metalic that act as a tape that one sticks to the lcd one since mine didnt had that much sticky i placed a scotch tape that joined them
[Nexus 7 (2013) General] edpete97:
So in trying to digest the 20 pages of this thread, I have a couple questions:

I just bought a brand new one of these, DEB, this week. In certain parts of my screen, only about 1 out of every 3 or 4 touches actually registers on the screen. The build date on the box is 2013/08 (which I assume means August 2013). Should I return and find one newer? Are the screen issues related to only those tablets build during a certain time? If not, should I just open mine up, even thought it's only 2 days old and attempt this fix?

I don't mind running AOSP as long as LTE works. Some people mention running CM11 but don't report back to whether AOSP roms suffer the same touch screen issues, or at least mine. I don't notice any ghost touches or multi-touch issues, just touches not registering in certain areas of the screen.

Thanks.
[Nexus 7 (2013) General] kylethelife:
I've done this to my N7 and it worked perfectly! I was so happy to be able to use it without that expectation of my touch not registering from time to time. Definitely great!

What I did was I unplugged it then plugged it again since I didn't hear any clicks or feel anything loose when I was pressing on the connection. That's all I did then I closed it and booted it up then it worked flawlessly. My only problem is, I didn't do anything to make sure it would it wouldn't loosen again and now after a few days, I'm experiencing some unresponsive touches (although not as bad as it was before I did the fix). Any suggestions on what exactly I can use to make sure the connection doesn't loosen up again? Hopefully nothing too complicated.

Then carefully take off the tape and detach the connector

Attach it as instructed in the OP.

And wrap it up again watch the USB connector!!!

The issue i was having was, if i did not have at least 1 hand, on the tablet, i would miss quite few touches.

With 2 hands on the tablet, it would not miss any touches.

So after a year of dealing with this, i decided to pull off my screen protector. Now everything works perfect.

Very happy to report that I fixed my touchscreen multiple typing and touching errors without any tools. The video on page 3 above shows how to open it with your fingernail. Be careful not to fold the back at the USB port, it can crack there. The wider, silver cable has a single connector on one end and two smaller connectors on the other end. One of the smaller connectors looked slightly loose. I pushed it in and the tablet started working properly. Thanks for the ideas posted here.
