Hello all,
My X10 has a few strange problems regarding freezes and reboots, and also problems with USB connections.
When my I applie pressure to my phone, it reboots. This also happens when I slightly bend my phone. It's a strange problem and I think (almost know for sure) it's hardware related because it happens in two custom roms (freexperia beta 4 by Zdzihu, and Achotjan_Froyo_2.2.1) and also in xrecovery.
The other problem I have has to do with my USB connection.
When i connect my phone to my pc. there is no notification and it doesn't connect to my PC. in contrast to other x10's that have USB connection problems (I've searched other threads) charging is still completely normal.
That's why I think the USB connection is software related
I was wondering if somebody has something usefull to say about either one of the issues, thats why I'm posting.
So if anyone has any idea feel free to post
...Life sucks?.... new phone maybe?

Don't bend it?
It sounds like a bad or lose connection some where on the motherboard. Has your phone had any hard impacts?

I'm not really bending my phone but "trying to bend it"or pressure lets it reboot. this would indeed be not really much of a problem, just don't bend or apply pressure. The problem however is that when I put it in my pocket, the same kind of forces (bending, pressure) will work on it and it'll reboot. this is pretty annoying because each time you'll get your phone out of your pocket it's rebooted or it still hangs.

Well yes it has, a car drove over it once but that's was more then a year ago, and it's fallen quite hard sometimes. I've opened it up however, and nothing is visible wrong (loose connections etc.)

Seriously???
A car drove over it and it has fallen quite hard sometimes?!
That makes the title of your thread misleading.
You should have mentioned these in the OP.
It's a miracle the phone works!!!
Of course something might be messed up inside
and probably not in a visible to the naked eye way.
If you want to hold on to the phone, maybe buy a hard case,
that will keep the pressure to minimum while in your pocket!
Probably a loose capacitor or resistor...
I'll agree with My_Immortal on that one. A hard case might help you in you situtation. But mate let me say this. From the injuries that your x10 has been through it's a miracle it still works!
Imho you should take better care of your stuff , it's a smartphone for God's shake not a buldozer!

Well yes indeed I could've said this.
But why I haven't is because it happened more than a year before these problems started. the bending, pressure problem started quite suddenly out of nowhere, and thus might not be related
(I also think the car didn't do that much damage, my phone lay flat on the road, and the car drove pretty fast (around 50 kph) so the car was actually on the phone for a very short time: less than 9 micro seconds .)
I've started this thread mainly because I thought maybe someone had heard about these kind of problems before and knew something about it.

I understand that the car incident was a year ago,
but in my opinion, it's very hard NOT to relate it with your issues.
Of course, there is always the possibility that it has nothing to do with them,
Have you tried using a hard case?

should open it and test across the components to see where the drop in voltage occurs, probably a simple resoldering would do the trick!!

As a Sprint Technician, this is by far my favorite thing to do. Even if it isn't necessary, I always dismantle phones and rebuild them just for the hell of it. Many times it'll often fix a lot of small glitches due to faulty assembly in the factory. (i.e.- touch screen bugs, dead keys on physical keyboard, speaker static, etc)

I love how open this phone is. Standard #00 phillips screws, and no warranty sticker!
newalker91 said:
All Samsung phones are like that. Very easy to dismantle them and interchange parts. HTC phones are next in line for ease of modding, although it requires the star tip screwdriver which can be tricky to get your hands on. They do although use tamper dots on one screw to know if you opened it, but you can order those online and put it on a screw head to trick it. Sanyo use the triangle tip and quite frankly are made of **** parts so half the time something falls apart when opening it delicately. Motorola is kinda finicky. Blackberry and Palm you aren't even able to open without destroying something, they don't play nice.
Tip to keep your phone running well: open it every few months, use a stiff paintbrush and gently clean all exposed copper with rubbing alcohol and then use compressed air to dry it completely. This helps keep electricity flowing smoothly without interruption by corrosion. It can also prevent shorts and lower heat. Just don't turn it on with any alcohol still on it or you'll fry the phone and don't brush too hard and knock anything off.

Story of my day everyday. As a corporate Sprint tech I take apart around 50+ phones a day.
It's become next to nothing to open any small electronic now...and a few big ones haha.
Sometimes I feel like I'm doing a tear down for liquid damage in my sleep.
I've done it for 7 years now and have been such a good harvester that I've kept my exchange rate down to 18% constant due to my efforts.
so.... did you see why people are having issues with signal?? is there a crappy antenna? etc.
tearing apart a sprint phone is easier than building lego's if you actually feel like doing it.
just don't tear the ribbon.

I do everything within my power to harvest parts and build up a stock of pieces I need, but we can't do any micro-soldering and the damn Evo charging port effs up my exchange rate consistently. Can't harvest motherboards so bleh. A lot of the powercycling problems and such as well are caused by faulty circuits and once again cannot be fixed. Do you have any tips?

None anymore, there was the old Palm circuit board switcharoo, but the newer models don't offer that. I harvest like a mad man though, even Pre sliders, pre earpieces on the top board/screen and things that many are too afraid to harvest (Blackberry tour/bold screens).
Soldering kits are being pulled from the stores too, since we've been scaled back to only soldering old pin charger ports (I still solder wires for earpieces and vibe motors) and those are now defunct.
If blackberry and htc hadn't screwed us over by taking away our soldering efforts with their models, we'd still be doing them today, but, thems the breaks. Hurts both techs and customers but maybe down the line they will rethink it and go with the soldering machines that are used at the warehouse to put new ports on. I'd dance a bit of a jig that day. And I absolutely hate the new standard mirco usb ports, absolutely too small and too fragile and they are on every phone now. Need to go back to mini usb, which was much sturdier. I haven't charged a phone on a cable in years. Cadex or Wall dock chargers for me.
Gives me better battery life, and since I always run 2 batteries I go to work everyday with a fully charged one. Can't beat it.
Well, is it possible to replace the wifi radio in my Nexus S 4G?? The low range and disconnects are killing me! I dont mind voiding my warranty.

Radios and chipsets are embedded into the circuit boards now, they aren't on a socket like CPU's on a computer motherboard, so no, sorry, that's not a removable/replaceable part.

Seeing that you are a repairs technician for sprint, I was wondering if you would be able to help me with a micro USB problem on my nexus s 4g?
Hello all,
First time I have done a post so firstly a hello to everyone. Secondly It is an update/ask for advice time from everyone.
I sent my Galaxy Tab 10.1 in for repair due to the newton rings problems and i have been checking it's progress online. Today a new status came up saying:
"Cancelled by ASC Non Defect (Working properly)"
When I called up customer services they explain that this could be due to two reasons:
1) They have deemed this as a default due to my use (apparently the more likely of the two)
2) For stats they have closed the case and are waiting for a part.
Has anyone had experience with these people and do they know any of their procedures? Also if they do say it was due to my misuse what are my options?
Sorry for the rant and new thread just need some advice asap.
Liam
I dont understand, why are they waiting for a part if the case is closed?
Worst case you can order a new unit, swap screens, and return it.
Remember $500-$600 for a tablet which costs $120 to make demands perfection.
Exactly that's what i said. The service rep was saying this could be a thing they do to make the statistics of cased open and closed better. However he did say this is a unlikely option.
ok, I think I understand now.
They closed the case because they dont want the case number to remain open in their system and pass SLA "service level agreement" time. This is pretty common in hardware repair.
If this is true then it does sound like they will replace the part.
Well that's good to know. At first i was thinking the person was just fobbing me off. I really hope they do repair the device; If not I will go mental at them.
Thanks for the info.
Also have anyone in the UK got theirs repaired yet?

Wait? It costs $120 to make it, or it's made of $120 worth of bulk parts.
The argument is valid, but not when you twist up reality to make it fit your point. There are other costs involved in making and getting the tablet into your hands than the bulk cost of the parts.

For anyone else who has this problem here is an update. They have agreed to replace it but it will take up to 28days. BO
Just buy a new one, swap the back covers, and return the defective one. 28 days is unacceptable for a repair.
Try blowing into the connector pin area & see if that helps you out. Others have reported it working for them. There is a thread in here about it.

Blowing in the connector does as much good as blowing in Nintendo cartridges. The screen is sealed and blowing will do nothing.

The assertion here being that they don't power on the device and check the serial number, etc., that is electronically embedded in the device? Does that really work?

Being the reason why it does actually help. Because the device is sealed you create a greater pressure on the inside of the device than on the outside. Since the back part is more flexible than the front it moves outward, obviously only slightly, but just enough to reduce pressure of whatever is pressing against the screen from behind. And as pointed out, it is only temporary, as when you stop blowing the over pressure seizes as well.
I also have the problem with Newton Rings, but I think it's because it is a little bent. The corners of the tab does not line up when I put it on a table.
Just thought I should mention this so you guys having newton rings can check if yours is bent as well.
It is not the best built tablet and it might bend a little if you have it with you in a backpack etc..

Solution!
I caught the famous newton rings two days ago after 2 months of ownership - and paniced at once. I read about all the disappointed users and returns and repairs. And decided to do the same. Got a ticket from the berlin workshop, that officially repairs for samsung. But i like experimenting. So i followed some leads before sending in. Put it in the fridge, warm it up on the heating. Both had no effect. At first. Disappointed, I let it lie beside my keyboard and continued working. When i looked at the 10.1 after 40 minutes again, the stain, that measured 2,5 * 5,5 cm in the morning and rather grew bigger when trying to treat, was shrunk to 1*3 cm or so. I did not trust my eyes. After another 10 mins, it was only the size of a fingerprint. And then - the whole screen totally went back to completely normal on its own. No rubbing or pressing could change that development.
My conclusion, and i can not believe, that samsung has not published that quickly and clearely, is that it is a moisture-problem. The weather these days is moist and also, i worked with the tab in moist surrounding lately. The "healing" set in, when i had the tab heated up to ca. 30 - 40 degrees celsius and then let it rest for some time with no cover in a dry room at 20 degrees celsius.
Try it before complaining, if you can live with thecircumstances. I do not know, if the replacement-screens of samsung is different, new at all or only dried by samsung... i will not send in mine anymore.
I can confirm, that the healing by administer some heat is permanent and also by doing the fridge and the heating again after the healing, i could not provoke any stain again.
Good luck!

ok guys, so i had this problem pop up a few months after i bougt it, so last week i spoke to the customer service rep and they mailed me a prepaid ups label, i mailed it to texas, 4 days later its back on my door step.
My impressions:1. They definitely changed the screen, the new screen has a slight texture underneath the glass, that isnt noticeable until you look really really hard.
2. The screen brightness, quality is unchanged.
3. The screen now has a dark grey samsung label on the bezel, my tab didnt have the label before.
4. The tab feels a lot more solid than it did before, not that it wasnt solid before, but there was always a very very slight creak when you handled it, especially at the back. It feels like everything is really really tightened now, feels a lot more dense.its a good thing.
5. I cant seem to produce the newton rings now, before they would appear temporarily when i applied slight pressure to the screen, or when i rubbed the screen to remove fingerprints, but now that doesnt happen. The glass feels a little thicker.
6. Another slight difference, is the fingerprints dont seem to show as much as they did before. Its not a major difference, the screen is still a fingerprint magnet.

It worked for a minute. Haha! What will I do to fix it?
Hya,
I'm new on here , so please be easy on me with my question :angel: . I recently purchased Google nexus 7 tablet from some local website who asks the customers to report any defect with in one day, only then they will ship new product :crying: , So I'll get one day for checking . Since Google hasn't launched Google nexus 7 tablet here (India) officially, so I'm getting the imported one, website support peoples even ain't aware of how to get warranty if product gets turned in to black box .
I saw some q/a here and I found many peoples having problem with product (related hardware ones) . I'd be thankful if you guys could list some basic things to check pertaining to hardware of product to make sure everything is fine
Hi, I'm on my 5th replacement and everyone had a different fault!
First you want to check round the edge of the screen to make sure the glass is flush with the case and not raised up so you can push it down with your finger, If anywhere the problem is normally down the left side. (DON'T TRY TO REPAIR IT YOURSELF WITH THE SCREW FIX TUTORIALS!) In most cases the fix is just temporary and the problem returns. This is a defect!
The next thing you want to do is check for dead pixels & white light bleed out around the edge of the screen. This app is perfect for the job.
https://play.google.com/store/apps/details?id=net.ujacha.deadpixel
Next you want to check the speakers by cranking them up to 100% and play several video or audio files to check for crackling/distortion/popping.
It's well known that the speakers are very cheap but they should still be crystal clear with the volume at it's highest.
Now you want to check the touch screens response. There is an issue with the screen not responding after heavy processing/game play where the screen becomes unresponsive down one half of the screen and only locking/unlocking the screen solves the problem.
First I would advise hammering the N7 with a game that is Tegra 3 supported for example Dead Trigger or Shadow Gun to get it nice and hot if at any time the screen becomes unresponsive then you have the same issue.
To double check run this app, you should quite easily be able to detect all ten fingers on the screen at all times.
https://play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester
The last thing I would check is the connectivity through Wi-Fi & Bluetooth, this is the least common fault as far as I know. Just check you have nice strong signals with no drop outs.
So after all that if you have managed to put a tick in all the boxes I reckon you have a sweet device!
I hope this helps you and any one else out there and that you have more luck than I had finally getting a perfect working N7.

Great question (although I don't know if it's a dupe). Thanks for all the info mr_tris. That sucks you're having so many issues. I haven't noticed anything wrong with mine since I got it yesterday, but I'll check all the things you mentioned when I have the tablet in front of me.
Billy
@mr_tris jeez!! 5 replacement means something and very horrible so to speak . I really appreciate help and advises you posted. I'll make sure to check them out .
The only problem I'll have if found any problem in device is that I'll have to wait another 20 days since the new product will be imported by website peoples for me to make replacement
One other thing to check: the gyro.
Does the screen rotate normally or do you have to turn the device so the screen is practically vertical (assuming you choose to unlock rotation via the notification panel).
If you are into gaming, try a driving game or something to make sure the cars don't veer left or right.
I had this trouble on my second one and have read of quite a few other people having the same problem.
The only real issue I've heard about is the screen raising above the bevel some. Yea this is a defect as the screws are too long and pushes the screen out. Returning it 50 times isn't going to fix it. Only by chance may you get one where the screw is slightly smaller (1mm). The solution is to make a little washer out of some plastic and put it under the screw. It doesn't need much to fix it. The cover pops off just like a regular battery cover and the screws are right there. If it is a problem for you, why NOT try to spend 2 min and just fix it yourself?
You wouldn't even notice unless someone pointed it out. You literally have to turn the N7 and look across the screen to even notice it. Hardly anything to freak out about.
Some people have blown their speakers already too. Most have been after a long session of movie watching or music. I suggest to not blow your speakers out (using at Max volume for extended periods) right out of the box. Let the speakers break in first. Honestly the speakers are so loud anyway that I normally have it at 50% volume Max. Probably not an issue either but its good usage practice.
I've also heard of one or two screens fritzing out with lines and fades. Probably nothing to concern yourself with.
I haven't heard of anything else but I guess it would always be best to check it out thoroughly.
I do recommend unlocking first thing because it wipes all data including storage and saves. I'm using EOS rom and its heavenly. Trinity kernel is also awesome because he tweaks the colors of the screen to pop more.

Screen - check viewing angles and color reproduction in the dark. Best reference is to use a site like GSMARENA for high res photos and screen reviews.
Body - Look for cracks or scratches, especially around ports and the headphone jack.
Things to disregard:
Slow system - this is just something you will have to deal with in an android environment.
Warm after prolonged use - again, normal.

The only real issue I've heard about is the screen raising above the bevel some. Yea this is a defect as the screws are too long and pushes the screen out. Returning it 50 times isn't going to fix it. Only by chance may you get one where the screw is slightly smaller (1mm). The solution is to make a little washer out of some plastic and put it under the screw. It doesn't need much to fix it. The cover pops off just like a regular battery cover and the screws are right there. If it is a problem for you, why NOT try to spend 2 min and just fix it yourself?
You wouldn't even notice unless someone pointed it out. You literally have to turn the N7 and look across the screen to even notice it. Hardly anything to freak out about.
Some people have blown their speakers already too. Most have been after a long session of movie watching or music. I suggest to not blow your speakers out (using at Max volume for extended periods) right out of the box. Let the speakers break in first. Honestly the speakers are so loud anyway that I normally have it at 50% volume Max. Probably not an issue either but its good usage practice.
I've also heard of one or two screens fritzing out with lines and fades. Probably nothing to concern yourself with.
I haven't heard of anything else but I guess it would always be best to check it out thoroughly.
I do recommend unlocking first thing because it wipes all data including storage and saves. I'm using EOS rom and its heavenly. Trinity kernel is also awesome because he tweaks the colors of the screen to pop more.

what Trinity kernel does the color tweaks?? i am on CM10 M-Series with Trinity V111, i dont see the tweaks any where??
I just gave a Nexus 7 to my wife for her Birthday yesterday. I must be working fine since her was on it all day yesterday and for the last several hours this evening. If anything was wrong with it, she would of discovered it by now.
When it arrives turn it on, set it up and enjoy it. Don't make urself miserable looking for flaws. If you don't notice anything out of the box don't go looking for issues. Trust me....

I wish I could have that attitude about my electronic devices. It would be a shame for someone to find a defect after the 15 day return grace period just because their device might be OK and they never bothered checking it. You must have spare money to burn. :what:

No I don't have money to burn lol but I just don't think its worth the stress of over examining for defects. If you look hard enough you will see that something isn't 100% straight or a tiny spec of plastic is sticking out or whatever and then it will stand out like a sore thumb once you've noticed it lol. Give it a glance over and if it looks good to you then enjoy your tablet.

I have flawless c80 here, no raising lcd, no others failures here.. You gotta have some luck sometimes.
I just wanted to report on a possible fix to touchscreen issues. While this may, or may not, work for you, it is what I did, what I have done on three(3) total devices & it is what has eliminated touch screen issues for myself & two other individuals.
This is a work in progress & I will be adding pictures & more detailed instructions, along with progress updates as I use the device going forward. This modification (though it really isn't a mod) requires no tools & while it does entail some light dis-assembly, it did NOT require breaking any seals that would void the warranty outright. Doing this however, may very well void your warranty, I am not an attorney, I am an engineer & taking things apart is what I have been doing since before I could even crawl nearly forty years ago.
To begin, I will go into my Nexus 7 story, which may allow you to identify similar symptoms.
My Nexus 7 device worked well out of the box, with only occasional multi-touch issues. As time progressed, the issues got worse & at one point a couple of weeks ago, even single touch event started to lag or not register. My Nexus 7 is a batch from July of 2013 & I purchased it in August of 2013, so it was still under warranty. Asus issued me an RMA number, however, I hate broken things, knowing darn well that 99% of the time I can fix them myself far faster than the total time it would take an OEM to get my device back to me. At any rate, after the 4.4 update, my touch issues got even worse. Aside from missing even simple gestures & taps, occasionally the screen would look funny & once it even had a sttatic "snowy" screen that was remedied by a factory reset.
After reading a few complaints from people about screen separation & investigating the device via the ifixit tear down, I decided I would take a look before committing to the RMA process. I gently slid my thumbnail under the bezel & slowly worked it around. Immediately I could feel the clips giving way & I eventually had the back cover off. Once the back cover is off, you will notice that the screen & digitizer ribbon cable runs across the battery, pinned in between the battery tray & the inductive Qi coil on the back cover of the device. I found it is easier to ease all the sides up slightly, then remove the back by gently lifing from the sides & upper portion, with the bottom, where the USB port is, being lifted up last. Once I removed the cover, I disconnected the battery terminal clip. After disconnecting the battery, I then followed the screen ribbon cable to where it is clipped into the screens board contacts with a plastic stay. Immediately upon applying pressure to the cable ribbon stay I felt & heard a faintly audible "click" sound. On closer inspection, I discovered that poor contact was being made by the ribbon cable & furthermore, the flex in the battery tray over time, when coupled with the heat generated at that location (due to the battery & the inductive Qi coil) can slowly loosen the ribbon cable stay & affect the quality of the connection. I used a thin piece of composite material to reinforce the cable ribbon stay & used a piece of vinyl along with a non-conductive adhesive to better secure the cable ribbon & stay. I only used a tiny amount so as not to affect the ability to safely disconnect the ribbon cable without destroying it. I also did not want a bunch of adhesive heating up & spreading to other areas. Before I performed the following step, I decided to test out a few thoughts. What I discovered is detailed in the next paragraph. So, after letting the adhesive dry overnight, I reattached the battery terminal clip & started the device. It has worked flawlessly since, without any touch issues.
While I had the back cover off, I carefully reattached the battery terminal clip & while wearing Nitrile gloves & standing on a wood floor to minimize the risk of static discharge, I would turn the device on with the display ribbon cable in various states of connection. They ranged from being angled so that the far contacts would make little or limited connection, to a full connection with varying degrees of pressure applied, to simulate a good or bad connection. Sometimes the device would not boot. Other times it would boot & have a static or "snowy" screen. Sometimes it affected all touch, from single finger events to multi-touch. It also surprisingly affected the system response. Things would freeze up & apps would FC or ANR. Again, once I improved the connection, everything was back to normal & functioning perfectly. In fact, it is functioning better than it did out of the box.
While I am sure Asus would argue that this voids the warranty, I did not break any seals. No tools were needed, just the materials I chose to use & had lying around. As I also mentioned in the opening, I did this on another household members device, that only had multi-touch issues, not all the issues I had, & their device has now been functioning wonderfully for the last several days. The display ribbon clip in their device was not completely detached on one side like mine, but it was fairly loose all the same. The third device was a friends & it was having mostly single touch issues, though he said multi-touch issues would come & go. We ran through the steps on Hangouts & his ribbon cable was in its place, but as he removed the back, the stay clip fell out. His device is also functioning normally now & he has not reported any further touch screen issues.
Since the problems people are having are oftentimes different & not consistent, it very well could be that this is exactly the issue. I would surmise that it could be the very reason why Google & Asus have been VERY, VERY quiet about the issue, since it would require returning the device for a fix, not simply a software fix.
If you try this, I urge you to be patient & use the utmost care when removing the back. While there are no cable attached to the back, you never want to force things. Be gentle & when you find the right spot for lifting, you will know it. It is not difficult & it is relatively harmless. I would caution you to use gloves & minimize the risk of discharging static electricity. I also recommend using gloves because copper sheeting is used in a couple spots & if you have ever worked with copper sheeting in electronics, you know that stuff grabs oils from your skin like crazy & you will end up leaving evidence in the form of an ultra-clear fingerprint that almost no solvent will remove. (Don't use solvents in your device unless you are a daredevil or know what you are doing).
So, that is my story & what worked for me & my small group. Ultimately, these devices are ours & it is up to each of us individually to pursue the fixes or mods that suit us best. That also means that the responsibility & consequences belong to each of us as individuals. What steps you are willing take to remedy any issues you may have with your device are decisions you need to weigh. This is XDA, where people take risks, assume that the are eventually going to brick their devices & make real modifications to devices (which this really is not). If you break something because you needed every single little detail & step spelled out for you, that's not my problem. Again, this is XDA, not some ragtime blog & anything you do here usually requires you to be able to think for yourself at some point.
Lastly, I will try to get to a step by step with pictures as soon as I can. I am not a developer, I am not a student & I don't have a ton of time to devote to answering questions. I will do what I can, when I can, but between the holidays & my job as a mechanical engineer (two large hospital projects are going on right now that take up 95% of my day), I have very little time right now. This post is the result of a large lunch review meeting, not free time, so it will probably take some time to get everything up. I have to recreate most of it, since I really figured on RMA'ing my device. I never expected this to work as it has for me.
Thanks.
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!

I barely have screen issues, but I am curious to know if this works, after replacing my N7 2013.
Thanks and regards,
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.
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?
Video might be tough, but I'll try to get to it. I will try to dedicate some time this weekend. I was thinking Saturday night, but I just learned that the Day of the Doctor is being simulcast in 3D near my house. So it may have to wait till Sunday so I can let my inner geek out.

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..
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.
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.

Well if it is pressure, I've found on past devices, sometimes batteries start expanding over time, like they have a fat belly.
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:

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
Also i got this blue dot too,and one pink as well. In middle of screen.

Absolutely no problem, GSLEON3, with profound gratitude I assure you that we really appreciate your engineering work discovering the problem. Take your time and we will patiently wait until you have the time to prepare a more complete review.
Wow! If it is so easy, I don't understand what the Asus support makes everyday.
Thanks for sharing it.
Sound really greate and promising. If you could, a tutorial video would be perfect for us, please

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.
