I tired searching but this is such a random problem, I didn't really know what to search for. So if you know of another thread - please let me know.
I was at my mall yesterday and saw that they had just gotten in new plastic covers for my Tilt. I was excited and wanted to see one on. They insisted on putting it on themselves. Major mistake... when she was taking the back piece of the cover off, she popped the case away from the phone. There is now a gap between my keyboard and the outer case by the camera button and power button.
I have tried for a couple of hours to get the piece back in where it should be to no avail. I still have a warranty on the phone so I don't want to just start disassembling the phone, is there some kind of trick to popping it back on without taking it apart?
I know that I will probably have to just let the tech at the store take it apart but I really hate to have him do that just in case I do need to use the warranty.
Thanks in advance!
I was trying to get to work and finally got it. There is a trick to putting that piece back. The keyboard needs to be pushed down right by the side and then it clips in. Thanks for taking a look!
Hi,
I've gone and stupidly sat on my phone and now the LCD screen has a dark patch in the middle of it..
I've tried gently rubbing which reduces the patch temporarily and also heating up with a hairdryer completely removes the patch, but also temporarily...
I think final solution is to tear down and replace the screen, does anyone have any suggestions on where I can purchase a replacement screen? Or where I can obtain one at all?
Thanks a lot

I think you should send it to HTC for repair... might cost more than trying to repair it yourself, but trying to repair it yourself could lead to disaster if you don't know what you're doing. Much better to have a professional repair it.
I have exactly the same problem :-O
Have been looking around here and i believe this is the same problem as we have, He fixed it with a sucktion cup so may as well try that
http://forum.xda-developers.com/showthread.php?t=462102&page=13&=#122
Thanks for the link mate. I will try the suction cup idea also and see if it works.
I have called HTC to find out about repair, they said (I'm in the UK), that they will send UPS to come collect and then they will give me a quote, it can take about 5 days to repair if I agree with the quote and £20 to send back to me... But they couldn't give me a better idea on price, although he said because the phone is new it would likely cost "a bit"...
I'll look for a couple more days for alternatives to fixing then it could be heading off to HTC
well the suction cup didn't work for me, tried to use a hoover as well .... all starting to sound rather kinky.
Will be sending off to HTC instead now. Thanks a lot anyway.
Get insurance and get a new one. Or get it fixed.
Same problem. Looks like nobody is selling replacemet parts for leo yet I've manage to find digitizer, but not complete with lcd screen. Is the phone too new maybe? Hopefully someone will start selling parts soon..
there are screens for sale , i think it's about 50 usd or thereabouts. You might want o search around i didn't save the link.
Today I found one by accident

Nope, that's still only the digitizer/ touch screen not the actual LCD screen which displays the picture
i guess you mean the tft lcd screen.

I did the same thing Xmas day and I ended up with a patch in the middle just like the photo I've seen in the thread linked earlier in this thread
after the initial shock thinking I'd broke it already, on closer inspection it looked as if I'd squeezed the liquid out of it so I thought why not squeeze it back?
all I did was press from the outside of the screen using 2 fingers either side of the spot and then quite firmly squeeze towards the spot. I did this in a circular motion around the spot thus forcing the liquid back into the centre. Eventually it was OK after a few directed squeezes and it had completely vanished so imagine my relief
probably a bit late now, gently rubbing as the original poster didn't work for me as that's what I did initially. Eventually I was brave and used some force but not enough to create more spots, just enough to force the spots away again and fixed it completely

Sounds like its going to be sent off to HTC Taiwan then... if the postage is £20
Ok I've been everywhere and tried everything short of breaking out the torx. I'm not under warranty anymore, and of course it didn't start getting dusty until after it ran out.
if i take the back cover off and blow compressed air in the slot by the main camera it clears most of it out but it's all back within days. i'm only getting dust in the front camera area, none in the screen itself that I've found [I've taken it out in direct sun with no screen protector and scrutinized it].
I'm wondering if maybe the screws on the motherboard are loose or something creating a gap, I've dropped it a fair share of times. I can find teardowns for replacing the screen but nothing specific on the front camera, and being a nervous nelly i want all the info i can get my greedy hands on. I *think* i know where the parts are but cant find anything specifically saying "THIS IS THE CAMERA NEWB". I'm perfectly willing to take the case apart and the board out but i don't want to touch the glass, i'd probably get more dust in than out.
So to summarize my request =p
1. Anyone know of camera specific teardowns?
2. Anyone have this problem themselves and fix it?
3. If it does involve taking the glass off would it be worth it to pay someone to fix it, or is it more cost effective to just upgrade?
Hey, lucky you I just cleaned it myself. At the price of almost screwing up my incs forever. Look up YouTube on dismantling the incredible s, take it all apart, clean it from behind and fix it back. Had some loose connection when I was fixing it back so my screen couldnt light. Now its as good as new. Advice that if you try, be very very precise and careful. Good luck! :thumbup:
Screen is seperated from camera, don't worry about getting dust in there. Use the replacing screen video, sufficient information for you to tear it up. No video guides to fixing it back unfortunately, so just download the video, find a player with the reverse play function and do as according(nahh I'm just kidding)
You don't need to be a technician to do this. No brains required. I don't have any. Have fun!

I "had" dust over front camera too!!!
I didn't mind it; I'm talking in paste tense because my phone should be now in HTC's repair centre in Como with:
-dust under the screen ( top left area)
-but mostly because part of the digitizer is gone: a vertical row of about 1cm on the right...
So I think it's a common problem, pay attention on the screen...
OK, I have found the issue that causes the touchscreen ghost touches, unresponsive touchscreen, etc. This guide is short and simple, and is provided with NO WARRANTY, TO BE FOLLOWED AT YOUR OWN RISK. This guide requires that you open your device WHICH VOIDS THE WARRANTY. Those of us with the original grouper/WiFi/2012 version are well outside our warranties, so that really doesn't matter now.
To explain, our devices use (to my knowledge) an actively driven capacitive touchscreen sensor. It has been narrowed down that a significant number of devices suffer from a grounding issue where the voltage potentials between the case and screen will cause a number of touchscreen issues when the device is electrically insulated from the person touching the screen. There are many YouTube videos and guides on how to diagnose if your touchscreen has this issue; I will not detail those here. To be simple, if you set your device on an insulated surface like a wood table and touch the screen with ONE HAND while not touching the device with your other hand, the touchscreen will go ape**** on you.
For those of us suffering these issues, it can ruin the entire experience of the tablet. I have deduced through a logical process the location and cause of this issue, which I will detail in the guide below.
The nexus 7 uses a filmed metal back, which is mechanically grounded to the motherboard via two "blind" gold spring contacts on the motherboard which touch the filmed metal backing of the case back. I call these "blind" contacts because there is no corresponding electrical contact for them to sit upon, simply the material of the case itself is what they contact when the case is closed.
What you will do by following this guide, is physically break these tabs off the motherboard, thereby breaking the circuit of the faulty ground point. The reasons this is successful in resolving the touchscreen issue appear to be twofold; first the ground points wear off the filmed metal of the back QUICKLY due to flexion of the plastic case back and therefore end up forming a SECOND capacitor on the device case back. This causes electrical potential to build between the plastic case back and the device itself, causing unreliable reading and operation of the capacitive touchscreen. Second, the intermittent ground connection causes unreliable grounding of this capacitive potential, which is worse than no ground at all in the respect of a capacitive coupling of the case back and the device.
These issues could not and cannot be resolved by a firmware flash, because it is a physical problem. Asus could not resolve the issue completely, because even if all components involved are replaced the issue will arise again due to the way the device is constructed. It was simply a poor design.
So, to get to the meat and potatoes of the fix;
1.) Pop the back off your nexus 7. Locate and REMOVE THE BATTERY CONNECTOR to prevent any possibility of a short while you follow the rest of the guide.
2.) Locate the two blind gold spring pins on the bottom right corner as circled in red on my attached picture. Note how they do not have any corresponding connection on the case back as the WiFi GPS Bluetooth and NFC antennas do. This is because these points were meant to found the case back to prevent exactly the issues we are seeing. However due to poor design they have become the CAUSE of the issue.
3.) Most simple step: break BOTH connectors completely off the board by gently bending them back and forth until they snap cleanly off the board. There is no chance of trace damage when doing this - the solder is MUCH stronger than the super thin spring connectors and they will easily break cleanly at the solder joint. If you do not break BOTH off, the touchscreen will get WORSE because you have simply enhanced the ability of the case back to form a capacitive coupling with the case back. So break both, or do not bother.
4.) Replace the battery connector and case back, ensuring you do NOT damage any of the other fragile gold spring connections, if you do you will lose some of your antennas and these connectors are a pain in the ass to replace.
I have attached a picture that shows the two points that need broken off the board circled in RED.
That's it, you're done. Reboot the device and enjoy a touchscreen that actually ****ing works. You're welcome.
Again this guide is provided at your own risk, I am not responsible for anyone who breaks the wrong connector despite my detailed guide, and I am not responsible for any other damage your fat fingers might cause while dicking around inside a sensitive electronic device.
I understand if some are too squeamish to attempt this guide, but I respectfully request that those afraid to attempt do not bother ****ting up the thread with useless posts. Constructive comments are always welcomed.
If this works for you as it did for me (I.E. perfectly) please hit the THANKS button!
I'm also currently unemployed, so if I've helped you and you are better off than I am then donations to my google wallet account are HUGELY APPRECIATED!
Once confirmed, I would ask that the mods sticky this thread.
Post reserved for future use.
And the dumb ****s at Asus tech dept. of course couldn't figure this out. Never again will I give Asus a dollar for anything.

Even if they knew exactly what to do the company is not going to allow them to "damage" devices in order to fix them. That's how Asus would see it, as damage. It is against the original, albeit flawed, design.

They don't do **** to fix anything, I sent them one, a 2012 N7 and they did absolutely nothing to remedy it, re-flashed the O/s or some such crap. I came up with a partial fix myself.
Just out of curiosity, have you done my fix and can you post confirmation so we can get the mods to sticky this thread?
As much as I'd love to get everyone's old n7 for dirt cheap when they think its "broken", I'd also like to see us snub Asus with our own permanent real fix as opposed to their bs runaround they pull until the warranty is up.
So please do confirm if possible.

Hi, Just replaced a broken screen few days on it with a new one and got lots of ghost touches and non responsive spots.
So I tried your suggestion and it works for me , I took a less destructive approach and just put some tiny pieces of duct tape on the back cover where the connectors touch it instead of breaking them off.
My new screen is in place and working properly :good: .
Thanks.

Mods please make this a sticky thread at your convenience, I believe this info will help a large number of N7 users, and it seems like according to the user above that it works when done in a non destructive way as well.
I ve had the same problem with my touch screen, it only happened when i connected the back cover of the nexus( i had a screen change)... so before i try to break the 2 pins i ve just put some electric isolation tape (plastic) and touch works like a charm.... thanks!!!
Be careful what kind of tape you use, some tape could make it worse.
You're welcome.
If anyone else has succeeded using this method or using tape, please post your results. I'm going to assume it hasn't harmed anyone or I'd have heard about it already.
Will attempt this tomorrow and confirm back. Using tape method.
Carried out the tape option, along with other additional fixes. Wipe cache, turn off animations, limit background processes to 3 and others. Seems to be working for me perfectly now.

Can someone please refer me to a YouTube video that shows how to diagnose if the touchscreen has this issue? Thanks.
It's so simple to type into google search "nexus 7 2012 touch screen problem video" you'll need to do it yourself.
Sorry.
Brilliant!
Finally I can now use my Nexus 7. At first I thought the erratic touches were due to the oil on the screen but upon replacing the screen protector, the erratic touches are still present.
Tried taping the contacts with a tape (A simple electrical tape would do), and much to my surprise, the device is usable now.
Also working for me, i just broke the pins. Much better now!

Tested the tape/isolator option (less hardcode) in my "bad" N7 (the other works flawlessly and they were both bough day 1, maybe different revisions, not gonna open that one incase!), and the ghosting hits and touchscreen ignore problems seem to be completely gone.
Thanks a lot!!
Thanks so much for the fix, it's a new tablet now. I confirm this works by using isolator tape over the pins. Very easy fix, took me 2 mins to do it... would have liked to know about it sooner
Thanks, I already had managed to solve partially the problem placing an aluminium foil into the tablet (risky and complicated so didn't posted), but this is easier and WiFi reception is better too. Anyway it is not perfect yet, same problem than my solution: try crossing axis vertically or horizontally (only one hand, tablet on a table) and weird things happen like no touch detected, very fast touchs, etc... I will post here if I figure out something else.
Havent seen anyone post how to fix the issue. Not the "fix" as in getting the pen to generally function again, but to actually fix the broken internal lever. I fixed my old g9x gaming mouse in the same manner. Im thinking maybe putting a tiny amount of superglue (or "Bondic" or similar) on the broken switch. Once dried, it could function as a replacement for the part that was snapped off. Im assuming it would still require dismantling the phone, so I cannot test it, but to me it seems like it would work. Anyone out there able to maybe test this out? I kind of want to take mine apart to peel off the white from under the rear glass, but with not having any income ATM I dont want to risk breaking my very expensive phone haha
only thing that is breaking ur s pen detection is broken lever..if you are able to fix it then ur s pen should work again..
So your only question is, was it the lever itself that broke or the switch attached to the lever - where would it typically break?
