I believe repair services work with better items theres even a chance for original parts. It will be more expensive but atleast its going to be fixed

The same hapened with me when i got a screen fixed from outside. Though they dis not charge me anything.. So finally got it fixed from lg service..
Ps: The glass has the problem Ask for a refund.

I just know that quality of available digitisers varies a lot. The first I bought was crap and the second is excellent...

Screen broke - what would you do

So my screen just broke and i'm in doubt between buying an aftermarket screen for about $20 and repairing it, or just say f*** this unstable piece of crap and buy the optimus 4x speed. So what would you do? Any suggestions for other phones? Any review on aftermarket screens? How easy is it to replace?
Thanks for your help and suggestions in advance,
Sincerely,
you're buying 4x? LOL you're buying a phone that doesn't have developers support, lock bootloader and no custom rom i visit 4x section sometimes but their development section is empty, i suggest send your o2x on lg to repair or search on youtube "how to disassemble optimus 2x"

It depends on how addicted you are to flashing roms. If you don't mind stable roms, and probably a very very slow 4.1 update, get the 4x.
If you simply need updates and the newest OS, repair the 2x. Honestly though, I think it wouldn't go as far as the 4x in terms of eventual updates, but still, it's nice to be able to modify your phone.
Yes i didn't notice the lack of custom Roms on the 4x this afternoon, so what phone would you buy? I mean the price of the 4x is awesome for the hardware you get, and if i'm able to root it i'm happy. But i also like to flash custom roms alot so do any of you know a good alternative instead of the 4x for the same pricE? Locked bootloader is kinda sucky .
I would really like to repair my 2x but i'm so tired of it and afraid that if i do change the screen i'll wreck the entire thing, and i'm not sure i wanna take the risk or just buy a new phone
Nexus 4. Don't know if it's cheaper or costlier in your country, but it's generally much cheaper. Beats the 4x easily in all fields, the only thing it lacks is a memory card slot. Availability is an issue at the moment, but if you can get your screen repaired for cheap now, then you can sell it after some time and get a nexus
I had the same problem. Repair the touch screen is very complicated, not because it's difficult disassemble the phone, but because the real display is glued to the touch screen with a particular clue. When you try to remove the display you can break it. It happened to me.
Repair and sell !

A couple of weeks ago I dropped my P990 onto asphalt and broke the glass. I taped it up using scotch tape to avoid glass splinters in my ears, and I'm just about getting used to all the cracks by now. I won't be trying to repair it, so I've got a nexus 4 on preorder. Hopefully it'll arrive before the tape crumbles...
Tl;dr: buy a nexus 4
This is a great reason to go get galaxy s3
Nexus 4! Don't bother with the 4x
They don't sell Nexus 4 in my country, because of LG, so yeah that sucks
I could get a Galaxy Nexus for about the same price
+1 for nexus 4 (except if you are addicted in slow updates and lg ui so go for optimus G(same hardware but i think quite costier))

Yeah but is it Gorilal glass? They say it's OEM in most cases, but don't specify wich type of glass this is. Last time i bought a replacement screen was for my X10 wich also was supposedly OEM but when installed i found out it was some kind of cheap plastic wich would never work comfortably as a touch screen. And it looks too complicated i would have to buy a hobby knife 3 sets of tweezer and a hair dryer only to switch the screen on my phone

They don't sell Nexus 4 or Optimus G in my country :'(
I broke the screen on my HD2, ordered one online for 15-20e , found a guy that repairs them, got friendly making mobile phones conversation and he changed it for 20e, sold the hd2 for 200e(I now regret it though) I would sell the o2x if course, it's nice but not the hd2. I actually am selling it

Me too, my screen was broken. I repaired at a workshop with 30 euros. The changed screen was old, taken from another phone ...
I also broke my screen and I had it replaced at a workshop. After the repair, the light sensor was not working so I had to return it to the workshop and wait another 3 day before they finally fix it.
The repair process including the new(?) screen was around 80Euro (~105$).
Get a new phone, upgrade excuse.
I got it replaced in a little Phone repair shop, they did a good Job, it cost 140 euro, but we got it back from ensurance because it happend on a holiday

As some people already said, it's the perfect excuse for getting a Nexus 4. You'll have a lot more support than with the 4X considering it's an official Nexus phone.

Have you tried calibrated it? I'm not trying to discourage you, but gyro sensor is hardware related and there's a chance that you need to have it fixed.
I've read in HTC One X forum where a guy experienced this and did everything he could and ended up in the service center and got a replacement.

When i try to calibrate it says "calibration failed". I got this phone as a gift actually , so im not sure how to check for warranty.

[Q] new digitizer, still not working!

hey guys, so i have the LG Optimus 2X, P990-HN, i'm with Fido (doubt it matters) anyway, there was a large crack in my screen, and i just dealt with it for a long time, but eventually the glass FELL OUT, the rest of it worked, but i couldn't leave it, so i ordered a new Digitizer from DealExtreme.com and it was about $50 CAD, reviews tell me it worked, googled it nobody else had complaints, so i doubt it's a fake or anything, all the way from singapore, i put it in and i can see everything clearly through it, beautiful, but zero response from the touch screen. none at all in any area, what could it be? also, if i take the screen out to re-seat it do i need to apply heat and completely remove it, and if so will that make it garbage and need a new one? will the heat kill it? i'm quite upset because it costed 50 bucks and took a long time to get here, and i finally put it in and it doesn't work, all help appreciated!
Have you tried the service center ? One probable way to check if the new one really works is to connect the old one back and see if touch works.. You might have accidentally pulled out some other connection .. just my guess

if i take off thte new screen with a hair dryer, will that ruin the screen though?
Not sure about that . Is the new screen stuck on to the device like a sticker ? I recall seeing some YouTube videos on Optimus 2x surgery

The digitizer , screen and the glass are usually a single unit .. yes any one of them is worn out , it can be replaced ... but u have to find d place where it s done ..

yes i ordered a digitizer though, replace it and it didnt work, what the hell could it be i just dont understand, and i can do it myself but i don't know the problem
I have done this twice with OK success. It is important to connect all electronics correctly - check YouTube for guides. But even if you did all correct be digitiser might be defect. Either you being it to service centre or redo digitiser install. Maybe, you can check before closing the phone, and if not working correctly check with your old digitiser. Heating and reheating should be no problem (although nothing is without risk). Good luck.

hey, thanks for helping me out. i think the digitizer MUST be defective, i took it apart and put the old SHATTERED one in, and it works FINE, aside from you know... being shattered. then i plugged the other NEW one in, and no response from the touchscreen. the ribbon wire looks to be fine, the connection to the logic board was fine, everything was hooked up right (or the other one wouldn't have worked right?) so if i cant SEE anything wrong with a digitizer, what could even be wrong with it, it MUST be defective, but what can really be defective about a digitizer? what can go wrong on something with so little to break...?
Don't know what is wrong, but it must have been defect before you got it. Try to return it to the seller/shop as soon as possible and get your money back.

Touchscreen not responding after replacing whole set (LCD+Digi)

Hi all,
i searched for the same problem everywhere, but no similar problem found...
My friend broke his digitizer glass in Z1 C6902. No matter where you press, touch was recognized as touch at the crack point. So I decided to replace whole screen with lcd & digitizer. I bought used original set, but it seemed to be cracked too, and touch was not working. I gave it back, and got another in replacement. It's quality was too poor, so i decided to get my money back, and buy new replacement kit (not oryginal). I bought fabric new set, replaced it and... Touch is still not working at all. I thought that it may be software problem, so I rooted the device and installed CM 12. But after successfull rom instalation touch is still not working....
What can I do now?
I checked all the hardware again, everything is plugged corretly, the connetor tapes are all right... Motherboard also should be fine, as the touch was partly responsive with first cracked digitizer. Phone works flawless with PC mouse, but I won't ask my friend to carry mouse with him all the time Please help me, it's a matter of honour right now (I have to fix it!).
Best regards.
Hello, i think you have broken digitizer, so you need to replace with another one. Just one solution for your problem
