My friend gave me a note 2 and it has a cracked screen. I was wondering if i should replace the screen+digitizer or just the digi. The lcd still works and so does the digitizer but a cracked screen just annoys me.

yes the glass alone is I'm thinking around 30 us dollars on the web the glass is glued together to the amoled lcd touch panel and can be removed with the following tools .....hair dryer highest heat setting, plastic tweezers, I actually took the whole phone apart to avoid heat damage to the internal components. apply heat to the whole screen from the outside only. caution very hot so wear gloves now slowly and I repeat very gently with tons of patience start prying off piece by piece then clean and losen the glue with alcohol then I used a stain remover I cant think now but will get back to you on that good luck

Hello guys
Tools Needed to separate digitizer
i got the digitizer from ebay,
hot air gun
exacto knife
i used IR thermometer to measure
double sided tape
first i thought removing the digitizer completely, and i experimented in old broken evo 3D digitizer to find out at what temp the glue between the glass and the plastic digitizer starts to lose(85-90degree Celsius)
after i found out that removing the glass pieces from the digitizer layer would be much easier,
my buddy helped me with the heat gun.
keep it moving don't stop at a spot it will damage the lcd,maintain temp between 85celcius(185F)to90celcius(194F)
using the knife remove the glass piece, remove one piece at a time.don't dig deeper when glass pieces are completely removed start heating at the top slowly peal of plastic digitizer layer from the lcd,
During this process maintain the temp at 85deg cel because dna lcd did't have the side metal support if the temp is low or you hurried means the top layer of the lcd will rip off .
after that i checked the lcd it worked no bleed or blackink
I cleaned the old glue and applied the double sided tape. the seller did't gave me pre cut tape so i have cut 2mm for sides and copied the old glue patter at the top and bottem . align the lcd use tape on the backside don't forget to peal of the soft key light diffuser from old one and transfer it to new one
i attached couple of photo taken doing this in a rar file
a pair of hands will be helpful and luck from Jesus .
Be careful with the knife i cut my fingers twice and glass pieces will fly around so wear glasses.
This is great news, however, I already destroyed my LCD in the process of finding that temperature. I was wondering if you could explain the pattern for the double sided tape. Does it not completely surround the opening around the LCD? Should there be a gap for the digitizer ribbon?

you need to make a slot for ribbon cable and holes for front camera and sensor.
Where did you get your double sided tape or could you recommend a source? Thanks

please help me, I have htc droid dna and want to replace LCD display with touch screen digitizer, does fit model X920e lcd with screen my droid dna? is X920e butterfly and droid dna lcd screen same?
I do not know if this has been mentioned or brought up before, but I just wanted to let the G2 crowd know that if they want to go the cheaper route and replace just the digitizer on their G2, it is possible with patience! You will be separating the glass from the LCD with a little bit of heat and a lot of caution, so as not to bust that beautiful LCD that these things are packin'. As you all may already know, the front glass is the digitizer so it'll all be replaced and your touch will work again, without busting the bank! This should only be considered if you're a very handy person with some superfine motor skills.
All you really need is a steady heat source of around 200F. I use a griddle, similar to this
http://www.walmart.com/ip/16451315?...56276670&wl4=&wl5=pla&wl6=34449323470&veh=sem
Most people have one of these laying around in a cabinet.
Get on eBay and find the digitizer for the phone and some LOCA UV Adhesive. 10ML is way more than enough.
Take the phone apart, then lay the LCD/Digitizer face down on that griddle and let it sit for about 10 minutes. Use a razor blade to VERY CAREFULLY and slowly peel the glass back. You should see the glass separating from the LCD. Continue this and take your time until all of the glass is removed. Then clean the LCD. It takes some work, this glue is extremely sticky and the only thing I've found to completely remove it is Clorox Surface wipes. They're the kind that come presoaked with some kind of cleaner. Even those take a little elbow grease to completely remove the glue from the LCD surface. It should be shiny. A couple specs wont matter, the LOCA has proven to be great at hiding imperfections. Next you will remove the LCD from the frame of the phone. There will be some connectors following through the bottom half of the phone to the PCB that has the charging port on it. Once the LCD is removed, add a line of LOCA glue to the LCD about as wide as a cigarette. Lay your new glass down on that glue, being careful not to trap too many bubbles. If you have a couple, no problem. You can leave them if it doesn't bother you, or you can push them to the edges. Next, align the LCD with the handy little lines that are printed on the back of the glass. Get something to hold it together, clothespins or hair clamps will do fine. After clamping, once again ensure the glass is aligned properly with the LCD. Then all you have to do is take it outside, let it cure in the sun for about 5 minutes, clean the extra glue up and reassemble the phone!!! I've got one waiting for a glass to come in so as soon as I get that I'll try to post some pics. Enjoy the savings, and the adventure!

Have a perfectly good LCD at home now with damaged digitizer and frame I'd rather use vs playing around with these crappy Ebay replacement parts I've gotten in the past month
It is not easy to replace but it is very easy to damage LCD, it's not so expensive to buy new screen with digitizer and frames (90-100$) so i prefer to buy full lcd and dont try to replace digitizer.
Hello. I have had a galaxy s3 with cracked glass and tried to replace it. I have seen many videos on youtube how to replace it. Basically people on these videos heat the screen and then remove the front glass easily, because the digitizer is glued to the lcd. But when I tried to remove it it came off quite easily, but only then I noticed that the digitizer was glued not to the lcd but to the front glass, so when i tried to remove front glass I accidentally broke the digitiser connector and somehow damaged the lcd. You can see photos here:
http://i.ebayimg.com/t/Samsung-galaxy-S-III-/00/s/MTYwMFg5MDE=/z/N0AAAOxylpNTUq5H/$_58.JPG
http://i.ebayimg.com/t/Samsung-galaxy-S-III-/00/s/MTYwMFg5MDE=/z/QREAAMXQ74JTUq67/$_58.JPG (in this photo you can see that the digitizer was glued to the front glass very strongly)
I would like to ask, do you know why the digitizer could have been glued to the front glass but not to the lcd? And why the lcd could have been damaged while removing front glass??
I would really wanna know the answer myself, as I ordered one that should have reached yesterday, but as they do not work on weekends, it will be here tommorow, and I don't wanna brake my display forever, especially because mine is not that damaged.
Any ideas?
my advice don't bother with a glass replacement. I HAVE TRIED TWICE and as the op said the digitizer is glued to the front glass. this has been the case with both the original screen and two replacement lcd/digitizer/glass assemblies that i personally took apart. each time the glass was fused to the digitizer . i used a heat gun and a laser thermometer and still i failed. I was successful replacing the whole screen assembly twice . but those cost about $130 from amazon,com. These replacements may seem at first like oem but the ones i got cracked very easily. they dont use the gorilla glass and the quality is not as good. one replacement was really bad in sunlight. could not see anything. after my screen cracked a third time i got a galaxy s 5 . and started using a case and screen protector.
I haven't seen this posted already so I figured I would share. Anyways my brother just got a S4 for $120 but it came with cracked front glass. I told him I would fix the glass for him (my first time touching a S4 let alone replacing the front glass). Well I meant to take more pictures, but in the moment I just wanted to get the phone done. I followed a guide on iFixit and watched a couple videos on Youtube, alot of people are right when they say that the Youtube videos make it look simple. Anyways this was my first time working with LOCA glue (removing and replacing).
Here are some helpful tips:
#1 Make a jig that will hold your heat gun above your workspace, you will need to adjust the height depending on how well your heat gun works.
#2 Put some clear packaging tape on the front of the glass to avoid glass chipping and flying, also to keep glass from entering under the glass and scratching the digitizer..
#3 The glass is easiest removed with a temperature between 155f and 165f.
#4 Work top to bottom. Ear piece to button.
#5 When prying the glass off MAKE SURE you are between the glass and the digitizer, it is easy to lift the whole LCD assembly.
#6 Work slowly, if the glass if badly broken it will not pull up as easily as a less shattered glass. I found that the digitizer was not as fragile as I was made to believe.
#7 Have plastic razor blades or a plastic putty knife/scraper handy for the removal and cleanup of the LOCA glue.
#8 Have 2 lint free cloths handy for the cleanup and removal of the LOCA glue.
#9 When the glass is almost off remember to pry off the back and home button sensors from the bottom of the glass.
#10 When it is time to clean up the digitizer use your putty knife/scraper to get most of it up.
#11 I found that Eucalyptus oil works well at removing the rest of the LOCA glue. Just put some on a Q-tip and swab the area you want to clean.
Here is a pic of what the digitizer looked like after cleaning with Eucalyptus oil.
EDIT: Sorry pic wouldn't link, had to make it an attachment.
I'm not gonna lie, while putting the new glass on I could not get all the air out, I did not get pics of the finished screen, but it only has a couple small bubbles. Well worth the $10 for the new glass.

nice write-up. shame that the image alone has over 500 views and nobody else has hit the "thank" button
well i thank you @fyca for the info and your time! :good:
Hey guys,
My first digitizer replacement ended up in a few big flower shaped flecks on the screen. That is not what I expected. I am very curious to know how these flecks appeared, or how I could avoid this will happen again. Also it looked to me like the original brightness could not be achieved.
This is the phone (Jiayu G2s) with the Calendar active which is almost an entire white display.
anybody who recognizes this?
oh, and by the way everything functions normal.

Looks like you overheated the actual screen. If you apply too much heat you will lose colors/brightness in those areas.
Heat not the only cause......

The "flowers" that you see can be caused by too much heat. BUT, these appear to be the result of excessive pressure placed on the display. If you press hard enough on almost any lcd or led display you'll see these kinds of patterns. If you let off they go away, unless you've pressed to hard or too long. AMOLED are particularly sensitive when heated. Long and short, be careful how much pressure you use when removing the glass etc....
I replaced an s3 screen twice. It was obviously easier the second time, as there was no LOCA to fight with. The main reason for diminished clarity and sharpness after replacement is the absence of the LOCA. Once u manage to get the glass off and do the necessary cleaning/preparation for reassembly, applying 3-4cc's of LOCA onto the digitizer in a vertically stretched "X" pattern will give u that genuine factory screen appearance. Well...After u cure it under UV light. But...for a novice, applying the LOCA and making it look good without permanently damaging the device is extremely tricky. And shouldn't b attempted if you're not somewhat of a professional, as the glue can seep down into your phone's internal hardware.

hi. thanks for the tip... i have 1 question at the moment, and it might sound silly... but what kind of eucalyptus oil did you use and where from? i did a search on it and there were all sorts of brands and use, and seems forms of it...
i like lighter fluid personally but its to runny but is perfect it you can keep it from behind the lcd and messing up the sheets on the likes of a LG G3.
The eucalyptus oil I used was an essential oil from my local co-op/natural foods store.
Go to lcdbondingusa dot com. They have this cleaner for cleaning LOCA. Man let me tell you, it's well worth the cost. I use a diabetic syringe to get it between the LCD and Digi. Sure does make easy work of it. It's great for other stuff, too.
" Lcd Adhesive Remover Cleaner For UV Glue OCA Glue iPhone & samsung Safe To Use" is the way it was layed out on the eBay page
I've got a Galaxy S III (i9300) with a very shattered front glass. The display and digitizer works just fine though. Menu, back and home buttons too. Everything is working, i just need to replace the front glass. I've once replaced the whole front package (LCD, Glass, Digitizer) on a Galaxy S2 very successfully so i have some form of experience.
Will be my first time replacing only the front glass. Unfortunately i wont be able to put any LOCA there as i dont have any UV light. I do however some regular adhesive 2mm tape that i will put around the screen to prevent dust and stuff from coming in. Also i dont have a IR thermometer and i will be using a hair dryer. I know how hot it has to be by feeling it. I should almost not be able to hold my hands on the glass. It might take a very long time but if its possible to do it, im willing to try.
What i'm worried about is the glass shards that are in the middle of the screen. Most shards end at the edge of the screen so i can apply pressure there when im removing the shards. But the shards in the middle have all edges on the digitizer. I cannot apply any form of pressure towards the digitizer so im worried of how ill remove them. Also the left lower corner around the menu button is full with tiny shards. like 0.5mm-3mm shards. Im wondering what is the best way of removing them? BTW i still got the touch screen protection plastic on. It got bubbles now cuz of the cracks.
Here is a picture of how cracked it is. Its not exact but close enough. Paint is OP.
The black spot in bottom is where the glass is simply gone. It fell of after time. I put some tape over it to cover it up so nothing can fall in.
Any advice on how to remove these shards?
Very appreciated
