[Q] Just a question about a cracked glass repair. - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello all, I want to first thank you guys for your support since I've joined up! I recently attempted a glass replacement on a note 3. The digitizer and lcd were ok before I removed the glass. During the removal, everything went smoothly, no cracked lcd or digitizer. It was my first attempt, so I did scratch it here an there, but they weren't too deep. They were negligible enough that they would be made invisible by the new uv-glue. So, before I fully removed all of the old glue, I turned the phone on to see if the lcd still worked and it did, however, I noticed that the touch screen was mostly unresponsive. It only worked at the top where the notifications menu is. I was able to pull it down about a quarter inch and then it would go back up as if my finger left the screen. I chocked it up to a dirty screen and possibly even the scratches I made on it. I read that those things would "confuse" the digitizer. I also read that cleaning the lcd and replacing the new glass with uv-glue would fix any digitizer touch issues, by filling in the scratches for one and by making contact with my finger more accurate. Anyway, I installed the new glass onto the lcd with the loca glue. Everything was clean as far as I could tell. After reassembling the phone I discovered that the digitizer was doing the same thing as it was when it had no glass. And now, when I turn the screen on from it being asleep, I see a blur where the unlock symbol is for a couple seconds, as if my finger was there above it. Then it goes away and the screen doesn't recognize my touch. I checked to see if my other note 3 did that when I turned the screen on and it didn't, at least not until I did put my finger there. I did a factory reset on the phone, disassembled it again and cleaned all the connections with alcohol. Everything looks like it's set up correctly. Just wondering if anyone has any ideas that aren't "the digitizer is broken" lol. I realize that may be the case, but I'm not sure what I could've done for that to happen. This will be my last attempt at finding a different answer before I trash the lcd. Thanks in advance guys!

I presume you've been checking the sites for help & youtube videos on how to do it all? Can you think of anything you might have shortcut or done differently?
The fact the defect was there before the glass replacement suggests maybe there was either prior damage that you didn't notice before trying this, or you've perhaps moved the LCD in such a way that prior damage has become apparent. i.e. there was maybe hairline damage and as you moved things the edges moved apart.
Could it be something along the lines of the glue is a bit thick at one end so the screen is now not contacting properly? How much pressure did you use putting it all back in place? Did it take a lot to get it even?
Wish I could be more helpful but, it's not something I've tried. TBH I hadn't even released AMO screens COULD be removed from the glass...

digitizer failure

well after 8weeks of my blackstone its decided to break, everything works normally but there is no response from the digitizer. the only thing i can see wrong is theres a patch where the digitizer and screen are making contact all the time (the screen is perfectly intact and no pressure has been applied at all) its a perfect square and about 3/4inch smaller than the screen. im not sending it back to htc, im going to repair it myself as i can have it sorted faster and im not that fussed about the warranty.
any ideas to the cause?
thanks

Any water / liquid /sweat seepage?
You can look into this thread for service manual and some user experiences.
theres no liquid in there, its as if the digitizer is stuck to the screen
managed to repair it, what a pain it was, turns out that the top and next layer of the digitizer were stuck together, the hard part of the repair was seperating the digitizer and screen but after 15mins of fiddling and nasty names i did it and it looks immaculate, this being said i never want to have to do it again

Blackstone's touchscreen

Hey guys! I have a problem with my Blackstone....
After a while of using it my touchscreen does not respond anymore....
It just stopped working. The display works exept the touch....
any help wold be much appreciated...

I have the same problem. Touchscreen do not response anymoore, I tried to reflash the rom, but it did not help.
you probably have the digitalizer broken.
I got this changed once about 1 year ago (under warranty). It seems to be a big issue on our old devices.
If you are out of warranty, it's probably not worth to send it to the service.
You may try yourself following this thread
Sometimes if you paste a tape on the screen and try to separate the 2 layers of the digitalizer pulling the tape slowly, it may work for a while (temporary fix).

Hi guys, I had this problem one year ago. My warranty didnot covered such thing and it was too expensive to repair it, so I have read all forums and found the solution. The problem is indeed in the digitizer however it is not broken just the covering plastic screen seems to be pressed to it and generating a continuous touch so when you touch with the finger nothing happens. There are two solutions to detach the plastic screen from the digitizer - either put tiny plastic card below the screen from the edge or use a duct tape on the screen and pull quickly - this step may need to be repeated several times until the two layers detach.
I have done both processes and it works. With the duct tape it is safer but the problem appears again after some time, with the first approach I don't have the problem anymore.
Hope this will help you.
yeah, I know it's old thread, but could you please elaborate on this .. ?
covering plastic screen - do you mean, the layer that is in front of the digitizer, the one you actually touch ? that stuf is glued hard, I dont see how you could place tiny plastic anything from the edge, that means that you need to unglue it with hot air .. ?
I am having the same non responsive TS problem, but I dont think that it is broken also. only things that could go wrong are ZIF connectors, and the digitizer integrity, which is mostly not the case cause of the firm plastic surrounding it.
please respond, you could use a pic with an arrow to show me cause im in the middle of dissasembly process. tnx

[Q] is the touch controlled by the digitizer only?Could I have damaged anything else?

Hi,
HISTORY:
I've had my defy screen shattered a while back and sent it to Motorola for repair (they did a terrible job at that). Ever since I got it back I can see small dust particles accumulating inside the screen. Gradually after a couple of months the top right corner became non-responsive and I left it that way for another 4 months until now!
As the warranty period was over, I thought of trying to clean the dust and see if that works. Unfortunately the connector on the touchscreen(digitizer) broke off and it stopped the touch completely.
My Question:
Is it possible that I had damaged something else(can something else be damaged?) that caused the touchscreen to cease functioning? :crying:
I can change the digitizer after buying it from ebay. But I would hate to waste any more money if this doesn't solve the issue. How likely is it that the touch functionality will be restored if I change the digitizer?
LCD is working fine, and I can use the volume rocker and power button perfectly.
P.S. please don't flame me for asking already answered question, I've been through a lot of threads before opening this one.

[Q] Samsung Galaxy glass change fail need help!

Hi,
I recently changed the glass on my s4 the repair seemed sucessfull as the screen did turn on and the touch was responsive however 24 hours later the screen has gone blank but the touch is still responsive as you can hear sounds when you touch the screen. There are no visible cracks.
The method i used was a seperating machine and attached the glass with loca glue. So what can have gone wrong. Advise would be apreciated and is there anyway to get the display back on.

The glue you used could have been too liquidy and caused a short circuit. If that happened it's fried.
It's also possible that the connecting cable that powers the screen simple came loose because it wasn't put in properly. That is what you should hope for because it's a quick and easy fix.
If heat was involved in the separation or gluing process it could have damaged something that took a full day to finally fail as well.
It could just be a coincidence that it failed right after you changed the glass, but I would put that in the "Highly unlikely" category.
Your best bet is to take the unit apart and see if anything looks physically wrong. Start there.
Most likely it has shortened as i have replaced with new screen and it works. How can i stop the screen shortening again if i do a glass replacement. And is there no possible way to recover the shortened screen.

There are probably no ways to restore a screen that has shorted out. Electronics do not mix when with electrical shorts. It tends to fry things beyond repair.

Help identifying type of screen damage.

Hi.
My S4 suddenly decided to not work as it should, I do not know the cause and would like help identifying it.
I have uploaded pictures of the screen. There is a colorfaded spot in the top right corner, very visible when the screen is off.
When I look closely at the spot, I can see a lightning pattern in the spot.
Is this due to a fall?
Do I need to replace my screen to have this fixed?
With regards.

the real question is can you live with it ?
there's no fixing something like that without a new screen. it's hard to tell if that is above the screen (delamination), or on the panel itself.
It looks like something, maybe liquid, is caught between the LCD and the glass. Or, lcd has started to separate from the glass.
Cheapest fix may be to have the glass and adhesive replaced by an experienced cell repair person.
Thanks for the reply. I'm guessing that the adhesive is to fault for this.
Don't know if its worth fixing as the screen is functional, but it is irritating.
Old phone so I guess I'll be looking for an upgrade.
Thanks for the help!
