Hello Guys,
i have a problem, i had already replaced the LCD-Screen because the old was broken.
But now i got a new problem... if i place the new screen on the digitalizer i got a glimer on the display. I don't now why. But i already discoverd that this effect only appearce if the LCD-Screen is on the digitalizer..
So what is the exactly reason and how can i fix this problem? Is the digitalizer cracked?
Here are 3 Pictures, one is without the digitalizer.
Thank You,
PS: Sorry for my bad english
did you try to fit digitizer in or just holding it upon the lcd?
what would happen if you rotate it 90degs?
are you sure there is no protection foil still on the lcd???
-
behind and on the lcd, there are reflection foils, bluring, light redirecting, polarizating. maybe 6 of them together. some are glued on screen, some are just below it. obviously there is something in digitizer as well, and those in your replaced lcd are not compatible with digitizer.
can you ask for return of the lcd and get another one?
the other option would be getting replacement of digitizer from the same shop.
or third, this effect doesn't look like it's from polarizator. polarizator is glued but those others are not. if it will not change if you rotate it, like with polarizator effect, means it's not polarizator and you can replace those other foils from below lcd. putting ones from your broken screen to the new one. It's quite difficult, but could be done.
okay.. if i rotate the digitalizer the effect changes..
in nearly 90 degree the effect is better than normal.. but not really good..
so is there a magnetism issue??
or whats the reason for this effect?..
could the digitalizer broken? but it's still working..
the display brokes because of violence..
could the digitalizer although broken??
no the digitizer is fine.
the replacement you get was not oem. means was not from the same factory.
someone working in there made some pictures or paintings of the lcd and showed it to his friend who owns a similar factory. He then made this lcd and sold it to you. As he didn't know what sort of, let's call them optic foils, have been used in the original he just put the ones he new were working fine with another mobile. But he didn't expect, as i am surprised too, that the digitizer have an optic foil inside as well. But before realizing, I suppose they already gave bonus to all those little workers and started overnight secret manufacture.
Before realizing the mistake, they already produced a lot of it. To cut the loses, I suppose they created a set of digitizers with a similar practice, which they would sell together with lcd and would be working good.
Now someone, your seller probably thought selling separate lcd would be ok too, so he did. That's why i was suggesting you have right to have an replacement, refund or an new digitizer from him at a fair price.
Of course don't take me too serious on the picture/painting matter, but otherwise I wouldn't be surprised if I came to true quite close
anyway those fake parts are a good quality and in most cases you wouldn't say difference. But shyt happens
as the rotating didn't solve issue completely problem would be those foils below lcd. if your seller would not be cooperative, you've got nothing to loose. open both lcds and change foils over.
Or get a fake digitizer which you would be sure is compatible with that screen.
If not successful, get a combo, lcd + digitizer.
hmm okay..
in the description is written original htc ware..
i had send my seller that problem and now we will see..
thanks a lot for those information..
I would be very interested in knowing how you got the digitizer and screen seperated? Arent they glued and most likely going to break easy?
did you mean the digitalizer and the lcd display or the front screen?
I opened one up once and the LCD appeared to be glued on to the back of the front screen (which I assume is the digitizer?)
ah okay.. eeerm.. i don't know that the lcd was glued on the digitalizer.. because my display has broken and the liquid was out of the display.. so the LCD was easy to take off..
But I've read some guys has warmed it firstly with a hair dryer and then they could take the display off..

you make me want to open ma rhodium.
if it's glued use a razor, or heat gun & blade like on apples.
then clean it and put new tape.

yeah dryer is maybe more safe just keep it below 100 cels. but it's not so vulnerable on bending too.
fake3: you sure you don't have protector foil on that lcd you bought?
i been playing around and get similar efect with a protection foil below polaroid.
there was still one protection foil on the front of the lcd.. but i already removed this foil..
but can you make a picture where the foil the polaroid is??

I was playing with just a generic foils. not rhodium.
They can put filters inside plastic nowadays. and mix even more of them and it's all still tiny.
If there is one in digitizer, it would cut sun reflections of lcd and would make good sense.
Glass could be tented, too. digitizer is usually one glass and one foil.
even if you would find something glued on lcd or digitizer, it's not possible to take it of without damage. I talked to people producing foils and applying them they can't take that off too.
There have you be one polarizer glued on front of lcd, otherwise you would see nothing. And they usually gluing one on back. That make the light more efficient. redirect light in useful directions, but is not necessary, that is another possible difference in your case. And probable, because it spares $ and space. But it's glued - no help there if that's the case.
but then there are all those which are dispersing light evenly, those you can try to change. They all have to be used in a set working together they create
something called Brewster condition, if that's not met, you see something like you see on your screen. every active foil is a part of it, and obviously there is something in your digitizer.
Just had another though, there is a small chance that htc decided to change factory or producing process themselves. and both are original. But I wouldn't say that's very probable.
So guys,
i solved the problem..
I bought an new Digitalizer from the same seller and now it works fine..
Thanks a lot for the hint with the different manufractures..
Greetz
happy to hear that
no worries
guys.. i wan to ask something..
my LCD is glued to my digitizer. since both of it is broken.. i juz throw the whole part away.
but then, i diden really glue my new / replacement LCD to my digitizer.
so i assume they did have some space in between.
although my rhodium works well now, but my digitizer only able to sense fingernail o stylus only. anything a tad bigger than fingernail, it wont pick up. neither my thumb nor my finger.
is this possible due to the space in between the screen made it so? or my digitizer was some lousy quality stuff?

The digitizer is a seperate part from the screen. It sends X - Y coords to the device letting it know where you pressed and the device coorelates that to what was on the screen where you pressed.
What I am saying is that you could have the two pieces seperated the screen in one place on the digitizer in another and you should still be able to press on the digitizer and have the device react appropriately.
The digitizer works independantly from the screen.
haha.. so in short.. it means by digitizer is lousy rite?
I Have de same problem, I need a new lcd screen but i dont know where buy
please help me
and i need the service manual
Thks
Hi Guys,
I have an S3 i9305, that I have replaced the screen (I purchased a complete screen & frame), Geniuine Samsung part where the screen and frame are already bonded together with double side tape. (did this after I cracked my original screen,). IT was pretty easy to replace..
Unfortunately, the double sided tape that attaches the glass screen to the frame is starting to come apart at the home button end.
Does anyone know any way to try and fix this.. its coming apart about 1-2mm, where I keep pushing it back down, but it's lost its stick.
If you've ever repaired one, you would know its practically impossible to remove the screen from the frame without Cracking it.
I've considered dropping a tiny bit of super glue just around the home button.. but worried I might stuff the mic/home button..
Any helpful suggestions on how to repair?
One thing I have just thought of is a case that pushes the screen down / clamps together in two parts that click together (like otterbox etc).. ie, where the case pushes the screen against the body..least this will stop the screen coming away.
Thanks for any help.
Hey!
A few months ago I dropped my SK17 and the screen cracked. Despite being cracked and with pieces falling apart, the screen worked perfectly. Yesterday I dropped my phone again and it stopped responding to touch. The screen looks exactly as before falling but it stopped responding to touch. The soft keys still work. Will replacing the screen solve the problem? I already flashed my phone to an original firmware but it solved nothing. I don't mind replacing the screen and spending a few bucks to get my phone working but I'd like to be sure if the problem's in the lcd.
Well, yeah, your touch digitizer might have hit it's stress breakpoint. Replacing the screen assembly will do the trick.
In case you didn't know, the display and touch glass are glued on the xmp, which makes replacements more expensive than expected. But whatever the cost is, it's better to spend ~35 bucks and restore your phone's full functionality than to keep using it like a brackberry haha.
Be extremely careful if you plan on replacing it yourself. Look around for the best/most trusted repair shop/center if you plan on sending it to someone else for repair. You really don't want to deal with wonky touch response or bad color reproduction because of a cheap replacement part, I know, I've been there.
Thanks, I was thinking in replacing the screen myself. I've already disassembled the phone up to the screen but I didn't took it off. Is it hard to take it off and put the new screen on? Do I have to glue it to the front cover?
Ok, if you have dissasembled the phone and assembled it back successfully, you already know the basic structure, so that's good.
The screen assembly is glued to the plastic + metal frame, and it's pretty hard to pry it apart. Make sure to use non-metallic prying tools and a heat gun (a hair drier will do fine). Using a heat gun gives you a chance to reuse the original double-sided tape, which is strong enough to keep the screen from lifting. Replacing this tape is not a good idea because aftermarket tape is not nearly as strong as the one that came with the phone (unless you manage to get 3M VHB tape).
Once you stuck the screen assembly to the frame, be extra careful when putting everything back in place. The frame has tiny clips which need to be PERFECTLY aligned, otherwise... you'll know it when you get there haha. You can leave the frame in place without the screws, it'll be easier to open it again in case something goes wrong (you wont need to open the phone from the back to access the display)
i recently dropped my phone and it got a crack in the bottom right corner around the back button stretching up to the middle of the left hand side of the screen, and i need help repairing it.
Im not sure if i can just replace the glass myself or i need to replace the digitizer or any other parts as the screen and back button still work perfectly fine.
I'd also like to know whether this job is easy enough to do at home as i am on a low budget, however i dont have much experience fixing phones.
much appreciated if anyone can help me
Replace the screen assembly, glass plus digitiser and oled screen. Trying to unglue the glass is very hard and the heat can kill the phone.

Replacing the whole digitiser is a lot easier, but beware cheap(ish) ebay parts - I replaced my digitiser with an assembly from ebay, but the glass in the replacement broke very easily.... replaced it again and it's cracked again, without even having a hard knock. Nowehere near as sturdy as OEM parts. Screen still works so leaving it for now
Words of warning...
I attempted to replace the glass on my S3 after I dropped it. I have over 20 years experience as a computer engineer and access to loads of tools. I watched numerous YouTube videos on the process before I started yet still I managed to break the digitiser. In the end I bit the bullet and bought another brand new S3 for £200. The cheapo replacement glass I bought from eBay did not seem very sturdy either - I'm certain it's not gorilla glass. My advice would be to get it fixed professionally by someone who uses OEM parts but then again, how close in price would that be to a brand new phone?
Hello all;
Upon replacing my charging port when pulling screen off I pulled the copper sheet (attached underneath of screen). Copper sheet got bulged, but it did not break. I flattened the sheet and after re-installation of screen the bottom half of screen would not respond to my touch.
Is there any way I can fix it without replacing the digitizer and screen?
Thank you
No way. It was precisely glued in a certain position.
It's amazing that a half of the touch is working.
Your best bet is to find a non-working phone on ebay and swap the LCD assembly.
Will cost you near $40 if you're lucky enough.
And, now you know how to disassemble the phone, at least.
Good luck.
P.S. Do not buy the phones marked "touch not working", there are quite a lot of them
