i9023 - Replacement screen touch input not working

Hi,
I recently dropped my i9023 and smashed the glass.
Bought a new screen with digitizer from global direct parts (www globaldirectparts com/Samsung-GT-I9023-LCD-and-Digitizer-Assembly-p/smsng6102150.htm)
Having put the new screen in it boots up fine and displays perfectly but the touch screen is not working at all and I can't do anything. If I put my smashed screen back in touch input works fine.
I've flashed back to stock I9023XXKB3 and I9023XXKB1 firmware, but nothing seems to help.
The ribbon to the screen doesn't appear to be damaged and because global direct parts had a minimum purchase of 2 I have 2 new ones and they are both unresponsive.
Anyone have any ideas?

My first idea would be to have the manufacturer fix it.

Sorry you are having trouble getting the touch screen to respond. I too have cracked my screen and would be very interested in your strip down and replacement steps as I am going to be doing the same. If you get time, could you write down your steps. There is a pretty good teardown at
http://www.ifixit.com/Teardown/Nexus-S-Teardown/4365/1
but I am not confident of the last bit of using a heat gun to separate the screen from the frame. Did yours come off easy ?

Yes I could have sent it to an authorized repairer but I would of been without the phone for a a while and it would cost twice as much. Plus I like pulling things apart.
markread544 - I pretty much followed the ifixit guide. however when pulling out the motherboard make sure the front and rear cameras and speaker are loose as well otherwise it wont come out.
I didn't use a heat gun, I just applied pressure until it started to lift, it would of definitely been easier if it had been warmed up but I didn't want to use a heat gun either. You would want to use an adjustable heat one on low if you did, I think a hair dryer would work as well.
I pulled mine a bit further apart then they did, the grey part in the attached pic comes off as well which makes it easier to get the screen out of the front bezel which it is also glued to.
Phone is back together at the moment with the cracked screen but I'll take some photos if I pull it apart again.

same problem here.
i bought an lcd on ebay for i9023 (slcd)
display OK , but no tactil response.
i had MP the OP but still no answer.
if you have any suggestion
thanks

how much for the screen? seems that 9023 is cheaper than 9020

80 euros for the less expensive , about 120-150 for the others

I ended up returning the screens from global direct parts and after about a month they gave me a refund.
After being quoted AU $250to get the screen replaced by an authorized repairer I decided to try again and bought a replacement screen on eBay from a seller called stream_beautiful for $86.
Got it today, installed and it works perfectly. No idea why the original screens from global direct didn't work.

I'm sorry to bump such an old thread, but I was wondering if there was any more information on this issue... I ordered an i9023 screen to repair a friend's phone about 2 months ago and had the same issue as the OP with it; touch input didn't work. I then contacted the seller (forceviewer on aliexpress) and he told me he'd replace it. After sending it back I then had to contact him again and send him pictures of the back of the old screen (with which touch input still works) because according to him there are 2 versions. Now I received the second screen a week ago and lo and behold, it exhibited the same problems. I noticed a number on the back of the screen is different, and the atmel IC (which I assume handles the digitizer input) has a different number on it too, however the seller has now adopted the position that it is definitely the correct display (quote: "If the pictures is right
The item will be right
I just send you the one same with your picturs
There are only two version.
Thanks")
Can anyone shed some light on what causes this? I know the guy's company tests their displays before sending them out, so that's probably not the problem, and receiving 2 faulty units in a row would be a bit weird, so I guess there's actually multiple versions (with a different digitizer controller IC?) which aren't compatible with each other... How do I make sure I'm getting the right one for my friend's phone? And, optionally, how would I go about convincing the seller to take this one back too and send me one that really works?

I'm having exactly the same issue...two replacement screens and touch input non responsive, re-install original and hey presto no problem...what I have noticed is that the part number on what I assume is the digitizer is different...
original -> KJ00423-101228-P00-7F-1
replacement -> KJ00423-101228-P00-5F-1

Yeah, my replacement says 6F-1 at the end, I can't check the original right now because my friend has his phone, but I'm willing to bet it doesn't say the same. Maybe I can make my case with this with the vendor, I'd really hate to have to buy another one of these displays for nothing

Guys,
It's the third SLCD screen that one of my fried is replacing to my I9023 Nexus S, and none of them is working. Yesterday he told me that when he bough the third one, the seller told him to "reprogram" the phone, because the drivers for new SLCD will be installed only then.
To be honest I didn't quite understood him, so, I though that the seller means to flash with a ROM. I did that, I installed CyanogenMod 9, everything went fine, but the touch still not working .
Does anyone knows how the phone could be completely wiped. Meaning everything what is in it to be reinstalled from the beginning....
I don't know what else to do, besides to buy a new phone

Hi All,
Just want to ask if anyone came to the solution yet ...?
Cheers,

no touch
Hello
i have the same problem:
1. The display works
2. But no touch reaction
i had bought a new screen for my I 9023 .
thanks for solutions

Yep, I have the same problem.
Original: KJ00423-101216-P00-1F-1
Replacement: (Not responding to touch): KJ00423-110207-P00-1F1
eBay Seller: mike410512

Bump - anyone sort this issue out?

I know this is an old thread, but since I have a shattered SLCD screen and i'm willing to replace it, i'd like to know what to do in case there's no touch response...

To get touch input again
Hi all,
I have smashed my phone screen twice on my S3 i9300. The first time I had the issue with the touch screen not detecting input but displaying correctly, I had taken it to an authorised repair centre and initially they did not know what was wrong.
There is only one way to "fix" this situation. You must remove the custom recovery and then reflash your phone with the stock samsung rom. Flashing the stock rom with stock recovery should pose no problem as it will be "official" and thus not blocked by stock recovery.
After reflashing, you must do a factory wipe + data reset. This is where you change your screen, making sure not to boot the phone for "the first time". If it does not work, repeat the reflash + factory wipe and try again.
The samsung rom will register the new hardware profile, and touch input will work. Why it works this way is beyond me, but taking these steps when changing the screen on a custom rom will ensure that the touch input works. Perhaps custom roms "borrow" drivers left over from stock rom? I don't know.
You can back up your current rom and restore after messing around with the samsung stock rom and you have gotten your touch screen working properly.
I have tried a whole heap of different "solutions" with this problem and this is the only one that works, and if you are taking it to a repair centre, make them aware that you have a custom rom installed.

Faulty screen 6039y

Good evening lads, I'm facing some problems with my display, the LCD presented some dots, more like small sqares(with sharp corners), they are not busted pixels (they're to big to be busted pixels), in different areas of the screen.. More on the bottom, and a few on the middle of the screen..
I should mention that i have not dropped the phone so that the dots would have an explication.
I made this thread in order to see if there are any other users who experienced this problem, and if they did.. What it could be done

Ive got a few on mine. I counted 6 or 7 just on the top half of the screen. A few on the bottom half. I only see them when phone is booting up on the black bootloader screen. They show up green.

Mine are visible all the time, Would vodafone warranty cover them ? Because, tehnically..it's not an software problem(That I could cause)

It has to. If you haven't dropped your phone,then those spots are hardware issue.
They gave you a faulty device,and you have the right to get it fixed/replaced for free.

I'm gonna go over there on Monday to see if they will change/repaid my device.
btw: I have an unlocked bootloader/root/etc, but..still, that is software, it would be impossible for me to damage the LCD trought an software :-s

You will have to return the phone fully to stock properties.
There is a thread which shows you how to fully restore stock rom,relock bootloader,etc.
Even rooting violates your warranty.
Bootloader unlock is even worse.

I did, I flashed an stock recovery, locked the bootloader, deleted the whole system/boot/cache,etc..basically wiped everything, and on my warranty chart, I noted that my phone isn't turning on after an update trought official app, and that I have white spots on the display[this was the one that interested me], so..They took it, and gave me a new one after an review in service[I forgot to make the partitions back as they were, but..they didn't looked there]
Thank you, T.C

We've heard of similar cases here on XDA before, sounds like a dodgy digitizer to me.
Had the same problem last year, after that I started getting these so-called snowstorms and my phone kept rebooting itself.
I ended up purchasing a new screen on eBay and was lucky enough to get a genuine one for about 70 Euros.
All went well for me, new screen's working flawlessly.
If the problem persists or even gets worse you should perhaps think about whether it's worth the money.
Removing the old display and assembling the new one isn't that difficult, there's quite a few YouTube videos out there.
If you have any further questions feel free to ask.
Edit: When did you start having that problem? I don't think it's probable but maybe it's got something to do with the ROM you've got installed. Try flashing another one (e.g. AEX Pie, LOS 15.1 or stock) without any custom kernels or boot into TWRP to see if you've still got the same issue. Play around a bit to see if the problem still persists. Remember to back up your important data. Again, this probably isn't the cause but it's still worth trying before considering to buy a new screen or phone.

No problem. Here's the link: https://ebay.to/2N7SQYO
Hope it's OK to post this on XDA.

I've suffered this issue since 1 year and last month the phone couldn't display itself anymore, my trick was to slightly twist the phone using both hands and it will temporarily enable the display, got tired of it and I went to a local mall offering mobile phone repair services, told them the issue, most of the shops refused or would just advise me to get a new screen buty persistence in telling that the screen is fine it might be just a small misalignment or loose contact and thankfully one technician listened to me and just asked if I'm willing to risk the screen being damaged and we'll what do you know he just re seated it and walla phone is alive again in fact I am typing this through my S5

Screen died - phone still works - is there a way to fix?

Hey guys.
So today my screen just randomly died. Didn't drop the thing. Used it the one second, the other second it was just dead. Phone still works. vibration, touch, sound etc still works, but the screen will not display anything, not even booting to recovery or fastboot.
Recently installed the global ROM. I got the phone in the original Chinese ROM. This poses a problem. Ordinarily, I would have sent this thing off to Xiaomi, but I am fearing that I may have voided my warranty by unlocking the phone and also installing the global ROM. So, I would greatly appreciate input on the following 3 points
1) What troubleshooting measures can I take to try and get the screen live again?
2) I have heard that I can flash the original ROM and this might help my case for a warranty claim. Problem is - 1) I cannot use the phone's interface, this might make it difficult to navigate TWRP. Unless I can control TWRP through the PC command line? 2) I never enabled USB debugging on the flashed ROM. However, i flashed something recently through TRWP (the Global ROM region fix), so I am hoping I can still flash things through TWRP.
3) If I cannot achieve the previous two points, is it worth sending this phone back to Xiaomi. I bought the phone through Gearbest and I live in South Africa, so I imagine safe shipping will set me back anything from 50USD to 150USD.

UPDATE: I managed to boot to TWRP - using the "adb devices" command brings up my device ID. Maybe there is hope for flashing the chinese ROM if I can simply navigate TWRP through the command line.

Is there not a fastboot image of the ROM you can flash? I'd send it back in anyway, chances are they'll just replace the screen and flash it back to stick.

Yes I believe there is. But I hope I can flash the original via MiFlash.
On another note - ive been doing some reading and apparently black screening on Xiaomi phones is actually quite common. I am beggining to think my black screen might be a software problem with having moved over to the global.
If anyone has some spare time - I would appreciate a step by step guide on how to revert to the chinese ROM (i am busy downloading it). I am hoping this might fix my black screen, and if not, then atleast I can send the phone back to xiaomi with stock ROM and make a warranty repair/refund
Thanks.

mi mix 3 very fragile
black screen, same happened to me, new phone, fell down and black screen. not broken , phone still vibrate, and ringing at a call . nothing shows up, useless . I had 3 xiaomi phones before, I broke the screen but they still work.
I destroyed a note4 screen after a car pass over it ( feel from my pocket driving my motorcycle,).and still work. I Have also a note5a prime with broken screen totaly working. Then I loved MI phones.
this mix3 is a ****, a little fall down,(whit gorilla protection in the screen and with
it the cover on it , and become garbage). I will not reapair it , will repair my note5a prime.
Lisent this : if you go fishing and your are not taking well care of your phone do not buy xiaomi mi mix3
it is slippery .
If you know any solution whitout replacing the display module, will appreciate. Regards. Martin

I had the same problem, do you have any solution without replacing the display?
Regards Andreas

my screen was replaced.. had same problems.

I broke my screen. Went to xiaomi hk and they fixed it. 860 hkd which I thought was fair.

White vertical lines showing up when i start my oppo a39.

My phone's screen was broken. So, i went to a shop and the repairer installed a new one. The phone was working fine. I updated it to Marshmallow but it has some brightness issues. So, i decided to downgrade it. I flashed my phone and after flashing, when i restarted it, my device is showing white thick vertical lines and then my device turns off. I tried re-flashing but still i have same issue. I cannot buy a new one as i am a uni student. I need help. it has almost been more than a week and i am without any smartphone lol. Kindly help me. Thanks! I have OPPO A39.
