My screen on my 7.7 has a few cracks on the corners and sides more towards the bezel, not really on the screen. It doesnt really bother me, the cracks have been there for about 6 months.
I have already opened the 7.7 because it took a bath and I had to change the board with the connectors to the headphone jack and power button whoch was acting up.
I have also helped a friend scratch the glas from his S3 which was completely shattered.
Now I was wondering if it might be worthwhile to change the glas on the screen, or might I damage it even more?
I googled and searched youtube but couldnt really find a guide or any info.
What approach should I take? Heating the glas up and try to lift it of? Dissolving the glue with isopropyl alcohol?
The main problem to me seems, you aren't able to get an affordable spare part. I also have a 7.7 with cracked edges, the only screens i found included digitizers and stuff which raised the costs far beyond 200USD, thus making the whole idea of fixing senseless.
Tell me if you found cheaper suppliers for only the glass part, I'd give it a try.

If you are interested, motherboard on my tablet is broken, but display is completly fine, almost no scratches at all. You can PM me if you want ( I would like around 120€)

So today my phone dropped on the ground flat on the ground from about hip height and after picking it up i noticed i now have a cracked screen from the top.
I'm wondering how much the plastic front lens will run about. I see some prices online for about 100-180$ and it seems like every1 is pointing to the g1 digitizer?
The touch screen features work properly with no problems at all. I'm wondering, is that whats really needed? Or is there just the plastic lens somewhere?
Don't really feel like spending around 130 bucks for accidental damage. Might awell wait for a different phone to come out .
I know you can order just the glass but I have never needed to repair the glass or LCD on a G1 or MT3G. From just looking at mine I assume you can seperate the digitizer from the LCD.
http://shop.ebay.com/i.html?_nkw=g1+glass+&_cqr=true&_nkwusc=g1+glasss&_rdc=1
the G1 digitizer is not a "plastic lens" it's the touchscreen, which sits on top of the LCD screen. I bought a replacement digitizer for relatively cheap on Ebay. If you are going to fix it be extremely careful. I managed to break the flex cable of my LCD screen fixing the digitizer....
I've just bought a cracked 16GB Nexus 7 for £40
Prior to buying I read a few guides but another one I've read has got me confused. They say if the touch is affected the screen needs to be replaced but if not its just the glass.
I thought the glass digitizer is the glass and responsible for the touch as well? So if that breaks it wouldn't affect the LCD, would it?
Also, has anybody got any advice for the repair. What side to heat etc.
Thanks

As far as I know, the glass and digitizer can come separately... The glass overlays the lcd/digitizer panel. You can replace just the glass if you need to. The glass does have some effect on the touch, as it transfers touch input to the digitizer. However, if touch still works with the cracked display (which it very well can work just fine), you can save some $ and replace the glass only. It's much easier to replace glass + digitizer, but more cost-effective to replace just the glass. Use your own judgement. If the lcd panel works fine, touch response ok despite the cracked display, then replace the glass. If you have the money, or touch is affected, spring for the entire display assembly- that's what I did on my S3, but then again, my display had burn-in which is an entirely different problem.
To replace glass only:
First remove as many sensitive components (ie battery, speakers, etc) as you can. You don't HAVE to do this, but it's recommended to protect them from the heat. Then, use scotch tape to tape the cracked areas of the screen- this secures the bits of glass and makes removal easier. Next, heat with a heat gun or hair dryer to a maximum of 180*F. You should probably use a digital thermometer (like you use for cooking or electronics) to keep an eye on the temp. Heat only the glass-side/screen of the device. Move the heat over it evenly and constantly. Once the adhesive is warm enough, you can GENTLY slide a long blade under the glass and release it from the lcd digitizer. You can also use a plastic tool/plastic knife. Be careful not to scratch the lcd, and gently clean it with 90%+ alcohol after you remove the glass, and before placing the new glass. Watch some Youtube vids to see the process in action.
NOTE: I've heard both that the Nexus 7 screen is held in place by adhesive and that it's held in place by retaining clips. I'm assuming it's adhesive, but I would get that verified before you undertake this project. Good Luck!

It can't be that hard to seperate the digitizer from the LCD.
It's got to be easier then doing a phone!
I'll just try it any way, worst that happens is I break the LCD as well.

True, lol... suppose it wouldn't hurt to try!
So im waiting for my digitizer/lcd to arrive but all things I read say the digitizer and lcd are fused and cant be seperated. I didnt even bother trying. So far dissasembly was a breeze. Used my daughters hair dryer and a small flat head screwdriver to seperate digitizer from the bezel with minimal breakage. This is my reference photo for reassembly

It doesn't look like it's even possible, can't find anything online about it.
I'll just sell it as new screens are £60 and I paid £40 for it (16GB WiFi)
Wouldn't be worth buying a new screen
That's probably the best thing to do, put that money towards a new digitizer assembly. I literally just changed the display on my Galaxy S3 and it was a breeze. Way easier than replacing the glass would have been (although I needed the LED panel, not the glass, so different situation)... Now I have a beautiful new screen. I hope my N7 screen never breaks! I would be extremely upset about that.
The thing that bothers me is, there's gotta be a reason they're selling the glass only and not just the assembly... apparently someone has successfully changed the glass only, otherwise I'd think they're just in it for a money grab- sell screens that are impossible to change and then cash in when someone destroys the lcd and has to buy that too. What a shame.

So what are you doing with your old digitizer? If it's already bad, maybe you wouldn't mind giving it a go and confirming whether the glass screen can be separated or if it is hard-fused...? Or can you tell just by looking that it would be an impossible task?

The glass you're referring to is the digitizer, that's attached to the LCD.
There isn't 3 units, it's the digitizer which is glued to the LCD and the digitizer that is the hardest thing to replace.
edit: actually that's wrong, it's the glass>digitizer>lcd
I didn't assume 3 units.. But everyone calls the layers (exterior glass and underlying lcd or led panel) different things, and I may have gotten my wording mixed up because I'm doing many things at once... I will edit my post accordingly. But that wasn't the point of the question though.
Anyway, I know on my phone the glass can be separated from the led panel. We've heard its fused for the N7. I was just wondering if the other poster would be willing to attempt separating them if they're just going to be throwing the assembly out anyway (since they're getting a new assembly). That's something I would do with a display that's already bad. But that's me.

After doing more research I know it can be done (it's bonded, not fused) but it's just hard, re-bonding looks like the hard part but it can be done:
http://forum.xda-developers.com/showthread.php?t=2337288
It's actually not all that difficult with the proper equipment, my only worry is the backlight
Agreed... I'm watching a video now about replacing the assembly & pulling the bezel off... That part doesn't look too bad, reassembly looks simple enough too... But even they were like "it's impossible, get a new assembly. All you need to decide is whether to get one with a new bezel or one without and salvage your old one."
That sucks. :/
Edited to add: just saw that link, it looks like a PITA! It can be done, but should it be done?

Hello,
I just realized I have posted before on the Nexus 7 first gen forum, then I came back here to share my experience with my 2013 model.
I got a Nexus 7 2013 tablet with a broken digitizer for free, I started watching info and videos on the net on how to separate that digitizer from the god LCD.
The heat gun solution looks a bit too hard to control. I chose to try to make my own heat plate.
I have made the heating plate based on stuff found around the house, also I borrowed some stuff from work until I will receive the controller I ordered from Ebay.
Basically, I got an aluminum plate cut from a scrap piece, drilled holes to hold those lock down clamps, everything is just made to resemble those professional separation machines.
There are 2 small round heaters underneath, each around 200W, more than needed for this application.
I tried heating the assembly up to 85 deg C and the lcd metal back cover starts to lift up, separating from the lcd glass itself, oops, had to press down on it and lower the temp to around 65 C ,now it sits in place.
I bought 2-3 broken digitizers with screens from a guy that repairs tablets just to practice before I really try to do the digitizer change on my own tablet..
I will put pictures of the removed and cleaned LCD’s, the digitizers were just used to practice the LOCA glue removal, I throw them away after. Too many glass pieces.
Here is the name of the video: Nexus 7 LCD separation from digitizer, fast LOCA removal. Please turn on CC on the video to see more info.
The separation of the lcd is done with guitar wire 0.007”, not sure if smaller diameter it will do better or not.
I had a problem on one practice screen, I cut thru the front polarizing film on the lcd. that’s why I started the separation from the lcd connector side, wire gets better there between the digitizer and the lcd.
One great thing I found is by using silicon grease, it makes the sawing much easier and you only need one pass to separate the lcd. Apply in small quantities beside the lcd before you pass the string.
After separating the lcd, cleaning up the loca glue is also easy, thanks to my other interesting finding I did, by using essential oils.
There are so many out there, like tea tree oil, oregano oil, tried them, they all do a good job.
I finally used the citronella oil because it was only 4$ for 15ml, probably you can do lots of cleaning from one bottle and also repelling the mosquitos around you.
As you can see, apply small drops, spread uniformly with your finger, then wait, after 4-5 hours the glue comes off very easy.
If any excess oil, absorb-it with a paper towel. If it’s too much oil, not good also.
The good thing about oil is that it will have much less ( more like zero) chances to go inside the LCD panel and make spots, like the alcohol can do.
Finished the cleaning with some 99% isopropyl alcohol ( from the pharmacy).
I’m sure after this, some people will try to sell “ miracle” loca glue remover. Hope this post will remain here to give some great info to those searching.
This is valid for any kind of lcd loca glue cleaning, is it a phone or tablet, it will work.
I think I will try to reapply the uv loca glue to the new digitizer, I will wait for the ordered glue to come.
With all the things I purchased maybe is not economical for one tablet, but the experience I got is priceless, I’m happy to share with others.
Thanks for the tip!
How did you assemble new digitizer with the LCD back together? Did you use LOCA glue? If yes, where did you get that?
Hellou,
Thanks for the tips.
Do you know where to find aluminium bar at size 7-10" diagonal in RO?
Thanks
Appreciated your tips re grease and oil. I've done this several times, so I know it can be done with some patience. The big question is, where do you get a separate digitizer that works. I've tried at least 5 that partially worked (dead bands, mostly), but found none that totally did. If you have a source, it'd help greatly. Thanks again.
Damaged my front glass display. No bleeds or dead pixels and digitiser fully responsive.
Can the glass be replaced alone?
Been to several local repairers and they saying glass display and digitiser comes as one unit and needs to replace all which comes to about 50% cost of phone. (Would written off if it was a car).
Seen some online vids using dry ice to remove the glass then reglue a new one followed by UV light to fix glue. (Sounds like dental work).
Any experiance on this?

This was possible on earlier phones even if they have digitizer and glass together, but you would need special equipment to do this, and it was a dangerous process where the chance of damaging the whole display was huge... On the Edge phone I do not see how it would be possible, because on flat screens you needed to take a wire and put it between the glass/digitizer and be careful by removing. After that you have to glue it again with UV glue.
The special point here is that with the edge screen the chance of breaking it totally is for sure more than 90%. Also as I have heard it is not even possible to remove the display on the s7 Edge without braking it. So if you need to replace just the home button, it leads also to screen replacement.

above link is proof of concept... it can be done... also several professionals in the US offer this service. I was just a bit bamboozled why its not being offered by anyone locally.
Hello there,
just bought a used X Style in good condition. However the phone is slightly bent, distorted possibly from heat. So when you put it face down on an even surface as on a table, it actually rocks... One of the things I cannot do now is to actually put a glass protector on its screen as it will not stick.
Anyone with a similar experience ? Is there anyway to rectify the problem apart from buying a new front housing? I can easily open it up and disassemble it but would it offer anything at all?
Thanks for your ideas

Is the back of the phone slightly curved from bottom to top, thicker in the middle? This is not bent, this is design.
Are the edges of the screen slightly higher than the rest of the screen? This is normal, it's a huge piss off, but it's normal. Research glass screen protectors moto x pure and you'll find that there are very few which stick to the moto x, let alone stick well. My guess is the phone is not actually bent, the back is curved as it should be and the screen is made slightly different, and not many glass screen protectors work.
Edit : face down it rocks...that's odd I've not experienced that, maybe it is bent and I don't know what to do about that
Thanks for your reply. But yes the phone is bent, and I am not sure which structural part is bent and which part of the phone actually follow suit. If I could identify the part that is bent, I could take it apart, replace the bent part (middle frame?) and then it would be perfect. What is also really funny, is that the screen is not broken nor split, as it seems to be elastic enough to bent without breaking...

No worries. I have no idea what part could be bent, but it's possible that there's a lot of stress on the glass and it could break at a later point in time. You could try taking it apart and see if you can identify what is bent, had the phone been taken apart or had the screen been repaired before you got it?
I ask because I had to repair my screen, did it myself, but had to glue the frame to the LCD. In doing so I used crazy glue, and then 3 months down the road the bottom quarter of my screen stopped responding to touch due to the crazy glue pushing up on parts of the screen and wrecking something inside.
