This question is directed to those who have taken apart their Kaiser, and specifically screen the screen assembly. I've got water issues and the screen is broke now. Here's the story. I might get some outrageous warranty charges.
I installed the InvisiShield (www.shieldzone.com) on my phone. Essentially it's a screen protector that is indestructible. It practically is, but unfortunately it destroyed my phone. To install it you have to spray this liquid on the back of the 'shield' and apply it to your phone, using a squeegee to get the bubbles out. It went pretty well, and I was happy with the results, but 3 days later my screen stopped working.
Everything is washed out, and it looks like water got inside the LCD somehow. For instance, colors streak across the LCD in fonts, etc.
I called ATT and they are mailing a replacement, and I'll be expected to send this phone back. They said if the return phone has damage that would void warranty (water damage, etc) I'll be prorated $400 on my next bill.
Over the phone the customer representative had me remove the battery and check one of the water damage pads to make sure it was white. It is.
For those who have seen internal phone assembly, is there any of these directly by the screen that will pick up moisture?
As far as ATT knows, the phone LCD suddenly stopped working. I'll get a replacement and /hopefully/ theres not a moisture pad right next to the LCD assembly. Anyone know?
Damn, hate those broken screen story's. Scars the **** out of me.

I dont know but man I hope that there isn't. Have you tried contacting invisishield? Never mind, b/c they'll blame you. Most applicators like that use alcohol to evaporate the remaining moisture that's left. My friend applied it to his, and he used very little liquid(scared), so GOOD LUCK!! I MEAN IT
Tough break, sounds dangerous to pour liquid on the screen though !
On a related matter has anyone seen pics of a Kaiser pulled apart ? Still wondering where the GPS antenna is located !
Yeah, I hope I don't get shafted.
I love the invisibleshield, and I put one on my $1,500 DSLR camera screen, but since the Kaiser screen is recessed a bit, when you squeegee the solution out from under the screen, it cannot be wiped away. It just gets pushed out between the phone's body bezel, and the screen glass -- right in to the phone. With my DSLR camera, the screen is flush with the body, so when squeegee'd I could quickly wipe the water/alcohol away.
Contacting Invisibleshield got me:
Our liability does not extend beyond our product. The lifetime warranty only covers the replacement of the invisibleSHIELD and NOT a warranty for the device the shield is protecting.

If ATT charges me the $400 if they find out, I guess I'll pay it. It's my fault, but by extension of invisibleshield. Guess I'll learn not to use that product on anything that has a recessed screen. I was thinking of buying an invisible shield for my laptop as well, but it's screen is slightly recessed like the kaiser, so you can forget me doing that!

That was why I bought the 'best screen shield on the market' for scratches (invisibleshield). Coincidentally that was the demise of my phone. I also purchased a steel case that basically would let me sit on my phone (uncomfortably) if i wanted. The desire to protect my phone, did the opposite in my case.
Wow what a horror story. Thanks for sharing with us - may prevent another phone from dying.
Wondering if you remove the battery and not using for a few days until the water dries out before turning it on?

Could be, zcink. The replacement phone is on it's way. I can remove the battery during this time it takes for the replacement to come and see what happens. Unfortunately, I think one of the following has happened:
1) Water seeped between the LCD protetcive glass, and the LCD itself, and somehow soaked in to the LCD causing mini shorts -- thus resulting in kludged text.
2) Water seeped to the phone's connecting cable where the screen input is, dried on the wires, thus creating a short -- destroying the signal.
Either way, when the liquid dry's, the mineral deposits causing the short will still exist, still causing a short. For both, repair requires disassembly, voiding my warranty. I could buy a new replacement screen from the China place for about $100, but if ATT /might/ replace it without screwing me, I'll take the chance. Just wanted to know what my chances /were/ them finding out it's got water in it.
I guess the moral is.
Don't buy from InvisibleShield, unless you use a SPARING amount of spray they they include. They include a huge bottle, and I used 2 sprays worth applied to my shield. This created enough excess to be squeegeed right into my phones body. The phone worked great for a few days, until one day at work, while I was using it -- BAM -- the screen was dead.
There isn't the water dectector there, but I'm pretty sure the technicians would notice the damaged screen.
I know those screen protectors, used them for alot of things. Using one right now actully. Its the one you wash with soap and warm water, and just let it dry, it have a static adhesive to the the scree.
I see. yeah hopefully the ATT tech will be lazy and just grant you the warranty without investigating. just play dumb. If they charge you the $400 call them up and threaten to switch to T-Mobile.
My phone died and T-Mobile was going to do nothing until I threatened to switch to ATT, then they replaced it.
I seriously doubt that they will be able to tell unless you really soaked it, next time use a dry screen protector, they work just fine, no bubbles. The only moisture sensor is on the battery, and if it was a tiny amount of moisture, there's likely no signs in the screen assembly. AT&T isn't likely going to dissect the screen to check.

Hadn't heard of that screen protector before, guess it would work well on an HTC Touch, not sure how the "full body" version works though!

Amazing find. Thanks!
It appears to me that the screen itself is it's own modular unit. Meaning, after phone disassembly, you'd have to disassemble the actual screen itself. Further, there is no moisture indicators directly by the assembly it seems.
Knock on wood, but I'd hope a tech wouldn't go that far to determine the fault of the phone. I assume they would if theres telltale signs of water damage to the display (streaking might be a common sign.) But, maybe, just maybe, they won't.

The service manual shows 4 of them, one under the battery that can be seen from the outside, one at the top and one at the bottom of the mainboard's other side, and.. one on the board that holds the bottom front panel switches, so very close to the LCD.
Personally I wouldn't have asked for a replacement phone, I'd have disassembled the phone and tried to clean it if made dirty by the liquid, bought a spare screen off ebay if it was definitely dead, and if ultimately it didn't work bought another phone off ebay for less than $400. But maybe I like risk

Keyboard membrane removal.
So, I've had trouble with my keyboard lately and wanted to just clean off the contacts on the membrane...but I can't seem to get the damned thing out of the plastic keyboard Middle Housing.
I have gotten everything apart so the housing is separated. Verified that I did it the way the service manual says...but i saw NOTHING about how to disassemble the keyboard from the housing.

Hi Guys,
I was cleaning my phone the other day when I noticed an ackward gap between the screen and phone. I inspected it and I've just noticed the screen is coming off the phone. I had a look around and it's going from the bottom to the top. Has anyone had this problem?
BTW phone is has been in a pouch for 1.5 years and I can confirm has never been dropped. Given the phone is out of warranty what are the chances Motorola will repair this for free???

Man, did you manage to fix your screen? I am having the same problem here, just like you I was cleaning my phone when I realized the screen was coming off on one side. I know its been some time since you posted this but I am just wondering if you managed to fix it.
I saw this problem on other smartphones, you should check your battery, because on iPhones when it happens when the battery push and finally detach the LCD from the frame

Right, it seems to be that issue.
Some early N6 have had battery troubles. Their batteries inflated because of warm which usually makes the back cover taking off.
You seem to have the same problem but pushing the front of the device instead. (back may be well glued)
Don't know if Motorola will take it back. Furthermore, they have been selled to Lenovo since that, so it may be difficult. In Europe, when warranty is over (2 years), you won't get anything from them.
Just stick it back to its position, it's not a big deal. Maybe you'll have to buy some special tape for this.
http://www.ebay.fr/itm/Rahmen-Kleber-Klebepad-Klebefolie-Adhesive-Sticker-Frame-Motorola-Google-Nexus-6-/272109920217?hash=item3f5b03dfd9:g:VH8AAOSwCypWnlXM Something like that. Don't know if it is a special tape or a basic one..
My Nexus 6 fell and the display broke. Not the screen but the display. The scratch's are inside. My device still works but I can't see anything and the touchscreen doesn't work.
What display/screen replacement should I buy?
I was thinking on buying this one: http://articulo.mercadolibre.com.mx/MLM-576031511-pantalla-touch-marco-motorola-nexus-6-_JM
Please check the link and tell me if it's the right thing to buy. Thanks in advance.
A pic of how it looks:
That's the right one.
That replacement has the frame too, if you want to save money and your frame is still in good condition you can just remove the existing frame from the broken screen, no need to worry about hurting the display as it's already broken so just break it loose, in pieces if you have to lol. Then just get one without a frame, just be sure to check the descriptions to be sure they include adhesive tape pre-applied or get a roll of 2mm 3M double-sided adhesive tape for $2 and do it yourself. While your at it you can also use the tape to re-secure your back cover after removing it if it needs any.
::EDIT::
Here is an example of one without a frame:
https://www.amazon.com/gp/aw/d/B00X...eywords=nexus+6+replacement+screen&th=1&psc=1
That seller it's a $40 difference in price without the frame. Also note how the speaker grills are attached to the frame, NOT the AMOLED. Keep that in mind when taking off your broken screen from the frame. If you are unsure if you can do it and feel safer just getting it with the frame, take 10 minutes before ordering and just try to seperate the broken AMOLED from the frame, if you succeed and find it by looking at it just how the new AMOLED panel would attach to the old frame then save $40 and get just the panel, it's already broken, might as well give it a shot, if you don't think you can attach the new panel to the frame yourself after removing the broken panel, order the one with the frame. ?
Thanks guys. I've got some more questions.
What process should I follow to replace the screen, should I dissemble everything? Any video tutorial you would recommend?
And, I've noticed that the phone doesn't heat up when I charge it as it did before (I have a Turbocharger), is the device ok? Is it normal that it doesn't heats up?
It's normal to have it not heat up when charging. Mine doesn't.
Jerryrig Everything has a good teardown video you can use.
What seems weird to me is that the phone usually heated up even if i wasn't using it (I guess fast charge) but now it doesn't.
Is there a way to know if it's charging or know the battery level other than looking and the screen? Because I can't see anything.
You should let the battery completely discharge, so the device turns off. That will help to prevent electrical damage to the components when you are disassembling the phone.
Letting the battery drain to zero is bad for the battery, for one. For two, the battery will be one of the first things disconnected, thus there will be no component damage.

Typed up a long response then posted and ticket was expired lol. All I can think of right now is the phone still works, just can't see anything. Let the battery die, call the phone to see if it's dead or rings/vibrates. After it's dead plug her back up and see if she starts, can call again to check if it's in fact booted into Android. Maybe someone else can think of a better way, I take it you don't have the LED enabled for charging so that sucks. Like the previous poster said, it is not advised to let the battery drain 100%, one time however won't hurt, just don't do it repeatably. Hope you successfully get her up and running again I still have my pre-order Nexus 6, never a screen protector, just a Seidio Dilex Pro case and not a scratch on the beauty, someone needs to make a SD 835 phone with dual front facing speakers before I upgrade!

So I like just about everything about the Sony Z compact line of phones but durability wise I have been unlucky. My first Z3 compact died from water damage and my 2nd one has a screen that is ready to fall off the device.
I choose to buy a HTC U11 to replace my Z3 compact as I have never owned a HTC phone before and thought I would try something different.
What I would like to ask here though is it worth trying to fix the Z3 compact to sell or not?
The only way to protect this phone:
The phone bends 0.1mm causes the phone screen to start opening. So it's not suitable for jeans pockets.
I remedied this by using an anodized aluminium bumper and tempered glass both sides.
Sony does a very bad repair of it's phones, and the issues will return, and their parts are expensive.
It is better to do it yourself and use B7000 glue, use plenty, easily removable for future repairs, no heat, clothes pegs, wait 48 hours before removing pegs or turning on the phone. And look for the best grade of screen with frame, Sony uses two manufacturers for its screens.
My Z3C has a screen that is lifting. This thread and others seem to indicate that fixing the screen is not hard but hardware is not my thing at all...
Would a phone repair place (in a shopping centre) be able to do this kind of repair? Is the phone much different to other phones that people would take in for screen replacements?
I don't care about the loss of waterproofing. The screen isn't even falling out, just lifted in the corner. I don't want to send the phone anywhere and be without it, or have it come back changed in unexpected ways...

Phone shops including Sony themselves have difficulty in repairing this particular phone, I think any phone shop can do this repair, but, they must use the B7000 glue or similar, or silicone, and not the red tape they usually use, it's useless, as this phone can heat up, or the blue z3c ready cut tape is not so good either. And if you get the wrong screen (clone), the colours will not be as good.
Many phone repairers have the clone screens that are thicker than the original.
The screen sometimes is actually bent, along with the body, check on a flat surface.
Always buy a good screen together attached with the body, and never by itself.
So armed with this knowledge and or hardware, you could go talk with a phone repairer... The first 3 times, shop, but maybe the fourth repair, try doing it yourself, it's as easy as opening a PC, just smaller, just follow z3c repair guides and youtube, when you're ready. When attempting to repair the phone, for the very first time, do it over hours, maybe over the weekend, and not one sitting.
If you start loosing patience, leave it for a while etc.

I got so comfortable with opening my phone, I put extra 0.3mm copper plates on the processor and gpu with Cooler Master Extreme Fusion paste etc. Lol.
But it's good to have an already damaged motherboard to work on.

Z3C LOS Omni Oreo
I put up with my screen for a long time but eventually the glue gave out and I had no choice. It was good, then bad, but ultimately ok.
I didn't have any trouble taking the glass off the first time because the glue was barely hanging on. I had a look and noticed that the headphone jack's glue was also failing. Probably why it was becoming unreliable. I glued that and reseated the screen cable and it worked fine while sitting there so I glued everything on again.
It was a poor first attempt. I had both too much glue (blobs that leaked out) and not enough to actually seal around much of the screen. No problem. I took the glass off again and glued it again. This time I followed the instructions closer and glued the front screen before connecting the ribbon.
The second gluing was good but something with the ribbon was wrong because it only worked when I pressed on the lower part of the screen. Sigh.
Taking the glass off after a good glue was much harder. I finally got the spudger under the glass but I moved it sideways before removing the suction thing. It was too much pressure for the glass. The good news is that it was the rear glass and only the bottom half shattered. I got the rest off and started on the front.
Now that I knew to be more careful, I got the front off OK. Reseat. Test and working. I glued the front on first again, without disconnecting the cable. Tested and working. I glued the half back I had on (covers the camera).
Its working!
I use a case so the back isn't even a problem, but I ordered a new back from China (cheap). The headphone Jack seems better. I put a new screen protector on. In some ways the phone is rejuvenated.
I was apparently not careful enough when taking off the screen though. I appear to have some marks on my screen now. It's minor, probably won't notice during normal use, but there if you look.
I'm so glad to have my phone back. I've been using an iPhone for the last 3 weeks.
Thanks for the tips.
Edit: The hands free speaker works again too. Bonus
Greetings,
Dropped my phone a full foot. Now the screen flickers green. I'm guessing the screen is broken. Any way to test that other than replacing it?
How do screen replacements go with this device? I'm pretty handy myself and might even attempt it if I could confirm it's the screen that's broken. I've done my own screen replacements before, but it's been some time.
Any chance the screen ribbon cable could be loose? There is no visible damage.
Thanks.
PS: of course, I have no insurance/protection. Oii.
Don't feel too bad, one time I dropped a pro cam on a ESD padded work bench top from about 6 inches and did more damage to that $7G cam than your smartphone retails for
$hit happens even in controlled environments... get a good case moving forward.
It could be a loose connector.
Or a fractured solder joint. The BGA chipsets don't like it when the mobo flexes.
You could replace the display only to learn it was actually a mobo failure. I lean more towards a mobo failure if there's no visible damage to the display.
Pull the cover and inspect it... an easy fix is always a great fix.

May not be as bad as it seems...
On my Note 10+'s I use the Zizo Bolt case. Without it my first one would be history by now, if it doesn't corner hit on a drop it face plants. I've dropped it close to a dozen times from 1-4 feet onto concrete with zero damage. I don't like handling it without a case as it's a slippery fish
A good case reduces/lengthens the G loading spike making impacts survivable as well as protecting the exterior.
A 2 layer design like the Bolt provides excellent drop protection. It's important that the out shell or whatever holds the case together doesn't come loose on impact...
For those memorable flying end over end multiple impact events. Even with a small drop though I inspect for damage.
I'm actually in a similar situation. Dropped my phone from about 1 or 2 feet and I have the green screen flickering as well. The phone works. I can get call and talk via headphones. But my question that I'm trying to figure out is if there is a way to put the phone into file transfer mode from a connected computer since I can't do it from the phone.

Uh-oh. If it was working before the plunge you likely either had a connector dislodge or suffer a mobo failure from the impact.
It's happened to me twice both from barely 1 feet. The screen itself was not cracked. Ifixit luckily submitted it as a manufacturers defect since the screen wasn't broken. The first time they were nice enough to not wipe my phone. The second time they did wipe my phone without telling me. Something about their policy uh.
Ended up going with the poetic revolution case. And it's handled a 2ft drop without issue. Had the Spigen tough amor prior.
They said just replacing the screen resolved the issue.
Sorry to hear this OP.
$hit does happen.
I was using an old htc 10 for about 4 years, I finally upgraded to the Pixel 5 on release day.
About a month late, on my birthday I had it on my laptop and it drops flat faced down on the screen.
by some act of God I actually had a glass screen protector on it and had no damage!
I now don't use a scren protector, but oh well.
Somehow the back glass camera is cracked though, even though it wasn't ever dropped after this..
I think I'll look into the 5a instead of fixing it. It's not much more.

The screen protector will transmit a lot of the G loading directly to the phone. Something is going to absorb that energy one way or another. Not always obvious either.
Ideally if you have a good case with raised display guards it will soak up enough of the energy so that nothing is stressed to the breaking point.
Mobos and cams are intolerant of high G loading and flexing. A monetary G spike of 2000Gs* can be generated by a fall from bench height to a hard floor. Hard materials absorb little energy unless they bend or break; they can readily conduct it though to internal assemblies... or the other side of the phone.

If they land on a hard floor on the body rather than leads they can pull enormous G's. As I got more experienced I was more careful not to drop IC's and to use ESD protocols with the more sensitive chips.
There are a couple of issues with dropped phones The internal bonds to the chip can be broken. Even more fragile is the mobo's solder flowed on components especially the BGA chipsets. No way to inspect those for damage. Internal mobo traces may also be opened. With bent frames and broken glass the odds the mobo or display will be damage increases.
Some of the cams have moving parts as well as their sensor's mounting points. More recently that became more of a concern to me as they aren't cheap and a pain to replace.
If the manufacturer uses lead free solder it's a death wish for the device. No lead solder is much more brittle and has poor flow characteristics making the bond is less secure.
Cell phones are exempt from the lead ban but who knows if they use it? No lead solder becomes even more brittle in cold temperatures. Conformal coating is also needed for fine pitch traces to prevent silver dendrites for forming with the no lead solder over time.
