[Q] Changing glass digitizer - T-Mobile LG G2x

I'm trying to change the glass digitizer on my phone, i'm also keeping the old frame, but when the glass was changed the notification bar was scrolling randomly as if a multi-touch was happening? any idea of what the cause could be. The phone is running stock rom and the adhesive used is lepage gel epoxy

When I changed only the digitizer, I never used glue to put it back... never had a problem with the touch.

I had just changed one with one that had an lg logo. It had these dots with connecting lines you could see when the light reflected on it. That digitizer had some issues with the touch scenceativity. I replaced it with one with a T moble logo, there were no dots or lines in it and it works like it was a new phone. I used a double stick tape to install them it holds good and if you have to remove it for some reason it is easy to heat with a hair dryer and ease off without breaking it. I guess I just got a bad one at first (lg logo one). Otherwise it was not much of a problem to change. The seller did refund 1/2 the cost of the lg logo one so I guess that was fare It works just not as responsive as the other.

[Q] HTC Sensation Digitiser Replacement Failed?

Hey, I have broken my digitiser (The phone obviously didn't like me, and tried to commit suicide or run away from my pocket, and felt on the asphalt) and replaced it with a new one, i had the tools and some experience so it was not difficult, but after replacing it, i noticed that when u "wake up" the phone u need to rub the screen for about 4 seconds, only then the screen starts to "respond" to your finger. Then i went outside with the phone - (i live in Northern Norway so it's -10 celcius ATM) and got this splat, as if an air or condensation, i tried to blow it off with the FAN ,and left it near the radiator for a whole night. But the Splash did not get smaller, if i remove the battery cover, and the battery itself, and if i twist, try to bend the phone, the "splat" Moves and gets smaller, if i try to press hard on the screen, the splat gets bigger. Do you think it's my mistake that i did something wrong in the process of replacement, or is it just the layer of glue, that's not dried up yet.
I'll attach the picture of the phone (sorry for the quality, taken from a GF's Wildfire,)
The unresponsive screen is a really common thing with a new digitizer. There is a thread somewhere in "general" thats deals with that issue. But for the splat, it seems that the cold seperated the layers of the replacement digitizer wich i guess is a cheap copy of the stock one and couldnt handle the cold.

Replacement Screen Problem

I cracked my screen a few months back, and right after it happened I bought a new digitizer to replace the cracked one. The install didnt go very well, since the tape used to adhere the digitizer to the LCD got mangled during removal of the original digitizer. Dust ended up getting between the LCD and Digitizer etc. One other problem I ran into was that the LED's that are supposed to illuminate the home/menu/back/find buttons were now shinning up into the screen and washing it out.
Anyways I got fed up with the dust and bought a new fully assembled screen/digitizer off ebay. I installed it last night and everything is great except that the lights are still shinning up through the glass and washing out the lower inch of the screen. I dont see why this would happen as there is really only one way to put it all back together.
Any insight as to how to get the lights to stop doing this?
Thanks!

Cracked my screen

Fell my phone from only 3 inches high to the cement ground, and cracked the screen, I just can't believe it! However the good thing is it's just the bottom left part where the back key is

Bad luck :/ Luckily my phone fell down many times with case and it's not cracked
Mine was bumped off a bench at the gym. Fell about a foot and a half onto concrete with thin carpet cover. Shattered like...er, glass. Had to buy replacement through insurance.

That's unfortunate. My gf has been really lucky with her falls (5+ car lap to concrete) without a shatter. I guess it depends on the angle.

I had to replace one through insurance as well....sat down outside at Starbucks and if fell about 26 inches, hit top corner and that was all she wrote. Was still usable but to beautiful of a device to stare at a crack on it.
Needless to say I placed a silicone case on it now
square trade help easy my worry of this happening to me. It would suck to have to re-root and load my roms though
how much does it cost to replace it, and can you do it yourself?
Dropped mine from my lap in the car to the ground. Cracked the top and bottom of the diffuser. Problem is diffuser is bonded to the LCD so I have to replace the whole assembly which sucks very much bad.... Oh and I had the case on it too... Smh

For those who have had to replace the screen, does dust now get under it?
I replaced my screen on a few older phones (some replaced by a service, others by myself), and like clockwork after a few months, dust develops under the screen.
I've almost pretty much settled that if my screen shatters, I'll get it fixed and immediately sell it to avoid that.
Best Case ist Otterbox Commuter or Defender
I hate Otterbox Defenders...so bulky & just ugly. I know, theyre for protection, but these new phones like the One X are just uglied up by the big bulky cases.
Anyway, as for the display changing...I just did a couple last week, no picnic at all. The person that said he changed one in 15 minutes I would bet the farm was a bad overexaggeration...unless you do 20 a day you won't even get this baby apart completely to even think about replacing the screen in 15 minutes.
As for $17.99 I haven't looked at the link yet, but I'm betting it's just for the outer glass (touch panel) and not the digitizer/combo assembly. I scoured the net and could only find the touch panel for this price. The combo (touch panel & lcd) as one fused unit I found for about $80, normally around $145 in most of the usual places.
These ship with the touch panel/digitizer fused, so separating them is basically impossible. I've seen a couple of posts where people say they've successfully removed the glass & replaced it only, but I'm guessing it was someone blowing smoke, or their screen has already been replaced with the 2 individual parts that are not fused.
I opted to choose the 2-part deal for one main reason...both of the ones I replaced were in cases, and fell a very short distance & shattered badly. I'm guessing like the OG Evo, there's really not going to be anything you can do to ultimately protect these, so I'm anticipating future screen changes...hence, the unfused 2-part combo.
I got the outer glass for less than $20, and the LCD for $35 both from Amazon. I was pretty thrilled when I got the glass, as the AT&T branding is gone & replaced with HTC instead. (I hate branding, especially since I use mine on Straight Talk)
I think the first one took me about 3 hours to do, the pieces are a horrible blind jigsaw puzzle of dependencies inside the phone, everything is gorilla glued & two-sided taped to death so it's difficult to break down without destroying important, fragile stuff.
After disassembly it wasn't bad with a heat gun to get the screens out, then made sure to clear out all of the adhesive which took quite a while...that stuff is gnarly.
Then I put in the LCD panel, got it situated & used 2 sided tape cut to around 1cm to edge the LCD for the Touchscreen to be laid on it. Added a LIGHT coat of some really strong bonding adhesive to the 4 corners & the middle of the 2 sides to make sure it holds but don't bleed out under the screen.
Laid down the touchpanel & applied firm pressure for a few hours before I reinserted the phone assembly back into the casing.
The beauty ring around the outer screen got a bit ugly on the first one, the second one came out pristine. No issues at all with bubbling under the screen, it's super sensitive & feels like they did brand new again.
The only issue I have, is when you're doing disassembly, one of the ribbons is held down by the very flimsy & fragile piece of circuit tape that the haptic buttons are in, and on both of them, the lights are much dimmer under the haptics than they were before. I don't think there's any way to remove & reinstall this piece without some minor amount of damage or degradation to the lights, but it functions perfectly fine.
All in all, it worked well, and if I have to replace a cracked screen again, it will be a much less expensive, easier fix the second time around. Also pay close attention when reassembling to your antenna wire, it has a connection much like the bluetooth wire you attach to a card in a laptop and if you're not very careful, when snapping back into place it can interfere with your antenna & your phone charging system.

So theres no issues with the screen changing colors? Like the old digital watches and calculators used to when you pressed the screen? I still haven't replaced mine and looking for an alternative to the 150 for the combo. Not really concerned too much with longevity, I'll get rid of it or redo it in about a year anyway so if it last that long I'm good.

Verizon Galaxy S III (i535) Display colors wrong after glass replacement

To make a long story short, my wife dropped her Samsung Galaxy S3 i535 phone a couple weeks ago and shattered the front glass. I ordered the replacement glass on eBay and proceeded to get it installed this past week.
One of the things I noticed was that none of the repair videos adequately documented how to route and attach the button for the home keys at the bottom of the screen. I was finally able to get the old home button ribbon cable detached from the phone and pulled free from its location. I noticed that there was still quite a bit of adhesive left on the resting location for the home key pc board (located a few mm in front of the ribbon cable that connects to the lcd assembly.)
I made the mistake of thinking that the adhesive consisted of some form of double sided tape, so using a small blade and a pair of forceps I began removing the adhesive. Turns out, the adhesive was attached to a felt-like material that was covering the back of the LCD. Once removed, I noticed that the section of the screen from which the felt had been removed was slightly discolored.
I proceeded to reassemble the phone with the new glass, and it is working correctly, with one exception:
The entire screen (not just the area where the felt was removed) appears to have a greenish tint to it. This is most notable when booting the phone. The SAMSUNG logo appears as almost a neon green (My wife assures me this should be white) and the booting animation is mostly green (She assures me it was multicolored)
A couple of questions here:
Did the piece of material I removed from the back of the LCD cause this problem, or should I be looking at something else for a solution?
Is there any chance this felt-like material contained the backlighting for the LCD Screen?
If not, could just a small section of missing felt allow enough light to escape to discolor the entire screen?
Also, since I obviously can't replace the felt, would coating the expose area with some form of paint or something work to restore the proper coloring to the phone?
I am currently looking at other replacement lcd assemblies which, from what I can tell, simply involve moving the motherboard from the old phone into the new assembly, connecting it, then putting the back cover onto the phone. If I can afford spending the $100-150 that these cost, I would like to avoid it. If this is my only suitable solution at this time, I would like a definitive answer so that I can make the purchase and get her phone back to working order.
Thank You all for taking the time to read my post, I can post pictures later to elaborate on what I am describing, but my wife and I are both at work at the moment and I don't currently have her phone to take a photo of.
Pictures would be nice. However your back light shouldn't discolor your screen. My guess is you loosed a cable or something else causing the screen to discolor.

I will get pictures posted this afternoon. After taking a little more time to look at it earlier today, it appears that Green and Blue colors are working, I just haven't got any red.
Do you know where to find a diagram of what ribbon connectors control what aspect of the phone?

A little late, but here are the pictures of my wife's Galaxy S III (i535)

that will give you an idea of the connector for the screen. you say all you did was replace the glass? not the whole screen? I cant imagine how this would happen unless you damaged the ribbon cable when removing the glass.
unless you want to remove the glass again you'll have to take it apart from the rear, which isn't too hard really. take the back cover off, then remove all the little screws you see. that piece of plastic will come off and this is what you'll get: http://imgur.com/WwoOgMP
the red box is the connector, make sure it's seated. i'm not sure you can get all the way to the digitizer panel from the rear, but this is simple enough it's worth trying before removing the glass again.
also there are plenty of youtube videos on how to teardown the sgs3.
on a side note, task killers are bad for your phone.... use Greenify instead, or nothing at all.

If this ribbon cable that connects to the LCD was damaged, it might be your problem.
In that case, you will need another LCD.
It's best to buy the LCD and Glass as one piece.
About $120 or more.

My screen replacement experience

So my S3 had a cracked screen. So I bought a replacement. Removed the old one using instructions on Youtube etc. My replacement screen was like $7 from eBay. It came with all the tools and some new double sided adhesive. I got the screen installed and it worked. Here's the tricky part. It was about half as responsive. I figured it was due to not using the LOCA UV glue that it comes held with from the factory.
So today I removed the replacement screen. Luckily I got it removed without cracking it. I turned it on and started using it without the screen and it seems like it is like stock. No damaged digitizer. Thank goodness. I have ordered some LOCA glue from eBay to redo the repair.
We have several UV boxes\lamps where I work for curing adhesive. So I will do the redo repair there with glue. I assume there was air gaps between the glass and digitizer. The glue should fix that. The best video i saw was using both the double sided adhesive and the LOCA glue. The guy used the tape on top where the ear piece is most importantly the bottom to hold the capacitive buttons down and also make them stick well to the glass.
If you are planning on doing this repair go with the LOCA glue. I saw several UV mini flashlights for very cheap that you could probably buy for $3 or $4 dollars to cure the glue. I wish I had kept the leftover clear double sided tape in hindsight to adhere the capacitive buttons down to get a good connection.
Yeah, I wish I read something like this. I had a nightmare of a time. I replaced just the glass initially, but when I would be pushing for a while, the glass would bend and press onto the screen. That was just the first problem.
Then I went to the developer options and showed touches on the screen. I seemed to have a non responsive screen at time, so I thought I'd see if my touches were registering. Aaand I had a touch that would get stuck on the screen. Cool beans.
Then like an idiot, I thought I'd ghetto rig it. I got some 5 min epoxy and slathered it to the screen and pressed the glass to it. That wasn't a proud moment. It might have worked if there wasn't a million bubbles in the glue.
So then I was like, screw it, I'll order an assembly from eBay.
I got my first assembly, put it all together and the touches weren't very responsive at all! They worked like 50% of the time. Not only that, but I looked closely at the whole assembly and realize that it was a horrible knockoff! The screen was smaller than OEM and the "Pebble Blue" was all kinds of messed up.
So then I ordered a new one that claimed that it was OEM and from Samsung. Cool
. I ordered it, and low and behold, SAME JUNK! I was so mad.
I went fk it. I ordered the screen assembly without the frame, cleaned my old frame off, and got it ready. When it came in, I wanted to cry, it was so beautiful and OEM. I returned all the other craps and got my money back from the one, but the other company that claims that it was OEM decided to send me another one! Even after they said they would give me a refund. I just shipped the second one back yesterday... Man, all said and done, it cost me $150 and a lot of time. Samsung would have done it for $176.95. Lesson learned. :banghead:
