Decalibrated touchscreen in tablet - Android General

I have really big problem. I flashed some china roms using Actions Pad product tools on polish tablet Pentagram Quadra Slim. On some rom touch screen was completely not working, when I flashed some other then touch was back but it seems decalibrated in that way that when Im pointing on middle of the screen is opening right corner notification bar. It's unusable. I used my CWM backup to go back to official rom but still nothing. I was reading about EEPROM drivers that are sometimes reflashed in digitalizer but It was about completely different much older tablet. I was writing on other android forum for help and no one replied to me... I would like to know some opinions from somebody. I will be really grateful for help.

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.

[Q] 5158N replaced with 5158N.. no joy

I decided to learn tablets..so I took on a TF300T repair for a friend to start learning.Looks like this TF300T was the wrong choice.
Background.
TF300T Original digi was shattered and was barley working. possible ghost touches
Andriod 4.2.1
Original Digi 5158N FPC-1 06WW 2010 on the sticker JA-DA5158N-IBB 18140-10120500
I did check a few post before I bought a digitizer saw the issues with mixing different versions. So I went with an ebay digi from china with the 5158 model. I received the new on visual inspection it looks exactly the same. New Digi revived no white label but printed in small black ink on the new digi says 5158 12.28 D4\ 11205019701012D. At the bottom in white ink it says 5158N FPC-1 06WW 1225. seems like a match
I replaced the cracked screen went pretty smoothly. I put double sided tape on the digitizer plastic frame after cleaning the old junk off. I did not remove the top cover from the new tape,I just put the unit back together without screw so I could make sure it worked the plan was to test, re tear down then glue/tape the new digitizer down after I tested. Well I get no touch after the 5158N to 5158N swap.
unit loaded the first time and updated the camera firmware but not the touch
I did check the fuse on the main PCB around the LCD/touch connectors and found no burning.
the first time I powered the unit up with the new digi the screen jitterd a bit but no touch. after resetting the cables still no touch. the jitters stopped.. So at this point I ordered a USB adapter to connect a mouse.
This morning I received the mouse connector. went into settings it said. Touchpanel version ELAN-3011-4822 Kernal version 3.1.10-g215ac8bf
Also had a message about DMClient has stopped on first boot. went away after a few reboots.
Today I tried a cold boot after reading some post. It booted up showing the three icons RK/ANDRIOD/WIPE.. up at the top I got the following line:
andriod cardhu-user bootloader <1.00 e> released by "U5_epad-10.6.1.27.5-20130902" A03
key driver not found...booting 05
starting Fastboot USB download protocol
at this point in the cold boot booting the mouse and keyboard seem to be unresponsive. If I hit vol up I get booting kernal recovery image then i get an android logo and big error message sits there and then boots up normal.Still no touch.
After 1st cold boot I went back to check the touchpanel version and now it says ELAN-0000-0000 the Kernal version is a tad different now its 3.1.100-G215ae8bf
Is this normal and Ive missed something? Could it not be working because I ave not glued the new 5158 to the plastic frame?
Do i need to root the device then flash the touch firmware? Seems to me that it should have just accepted the new 5158 and worked that's why i spent the extra cash to avoid this kind of issue.
Any words of wisdom from some TF300T gurus would be a big help!
Forgot to mention at the time i replaced the touch digitizer I did not know to turn the service switch off. the battery was drained as it had ran down to nothing because I could not touch the power off. hopefully this didn't screw me?

Barring any hardware malfunction, the only way to find out is to root the thing and flash the firmware anew through ADB. This issue has been discussed so many times, it hardly warrants a new thread.

Thanks for the response. I apologize for the new thread, most of the other threads seem to deal with swapping mis matched digitizers and then flashing the rom. I thought because mine was an exact digitizer match it may be a different situation. i was just hoping that my experience had rung a bell and someone may point out my error.
At this point I'm pretty sure its not hardware the microsd card reader that shares the touch digitizer board works. and the touch ELAN chanaged to 0000-0000 only after I did a cold boot.

Hi, i have the exact same issue. Also the system/etc/firmware/touch folder does not exist. I made it and put inside fw. The device whenever reboots it doesnt automatically update fw from the touch folder as it should. Through adb shell i always get error. Seems like the mobo not recognising digitizer. I also put the old broken one and still the same ELAN-0000-0000 i also forgot the off switch but i cant find any "weird" coil. Any help would be appreciated. I have read the other thread and learned a lot but nothing specific to this problem. Also my micro sd port was not working and i really thought was the pcb, but then i manually updated to the latest asus fw (from 4.1.1 to 4.2.1) and instantly micro sd works. When it wan on 4.1.1 i could find the touch folder and 04-3021-7038.ekt was inside (no label digitizer was the broken one and the new i bought as well). After the 4.2.1 update the touch folder disappeared and had to remake it. Tried with 04-3021-7038 and 02-3011-4820

SM-P900 Wifi Touch Screen has Malfunctioned

Hello All,
In my attempt to root the device which I was successful in doing somehow things went south when i tried to flash TWRP on my device. I performed the .img to tar.md5 conversion with the CWM Tool on another thread then i flashed the file to my device, afterwards the devices were rebooted and now I am unable to touch the screen with my fingers and only my S-Pen works, which tells me hardware wise the screen is ok but something software wise is causing this issue. Can someone please help me in troubleshooting this issue. I seen another user have this same exact issue but it ended with him sending it to the service center. I have performed a full dat/factory reset.... I have performed a full reflashing of the stock rom i have re-rooted. I am all out of options.
See video i made regarding this issue.
https://www.youtube.com/watch?v=orLEnWhlATo
Thanks in advance!
Can anyone help with this
Capacitive touch and spen use 2 totally different chips inside the tablet. The spen uses a Wacom digitizer, while touch interaction is processed using standard methods.
In fact, each one has their own ribbon cable from the screen to different points on the motherboard.
I have no idea how rooting broke your touch ability, but the spen working is not an indication that the touch interaction is not damaged in some way.
I can tell you that on mine (especially when using papyrus) it has a tendency to lose touch until I shut the screen off and turn it back on. Maybe something screwy is going on with the touch driver. Flash back to stock and see if it's still broken
Did the reset work?
I ask because we just got a used tablet off ebay and it is doing the same thing to me. My wife emailed Samsung who said blah-blah-blah so we are stuck with it. I know enough to brick a phone really fast, but I have been running custom Roms a long time and have replaced screens so I may check the cables on my day off.
But it was doing it before I rooted it, recovery, and Hyper-drive Rom.
though the knox had been tripped before I got it, so I don't know what has been done to it before this. So please let me know what you think even if you try it and it does or doesn't work and I will gladly do the same for you.
Thanks--Rick

urgent Help Moto x pure Edition touch problem

I replaced the screen on my Moto after it broke. Completely successful closed the back but i didn't put the screws i wanted to test it first, but after testing i found out the bottom (back, home and recent apps buttons) doesn't respond to touch, and im sure i never damaged the screen i was so careful and more secure.. so i thought maybe it was just a cable connectors maybe or sumn similar, so i fully reopened again and start to connect all the cables more careful one by one. After i was done before i put the screws again i had to test it, and this is what drives me crazy.. this time the touch was not responding from the bottom to like few more inches up, close to half of the screen i can say,like i made it worse this time, i didn't bother opening again so im here asking for what could be wrong? the screen is super clean never dropped never scratched it was just new one i bought it for like $61,Any ideas as to why that might be wrong here? i want to back up via twrp and root but i cant do it since the bottom wont respond to touch and neither twrp has no rotation feature.
help anyone?
finally fixed the problem never mind anyone having same problem i will be glad to help

problem after screen replacement

Hi there,
I hope someone can help me. This is my last chance
Last week I broke my screen and replaced it with a screen I bought from Ebay. I did this more then once for friends, so everything went perfect
The screen works, touch works, colors are fine, but the aligment is wrong.
If I touch in the top region, then it takes the higher part of my finger
If I touch in the middle region, then Everything is fine
If I touch in the bottom region, then the lower port of my finger is used
This is not possible to get used to. So...I think I need to recalibrate my screen some way..
I looked and found a tool from 2012 or so, but that did not work because it cannot install. (TouchRecalibrate.apk , calibrate.apk, ..).
I looked for other apps in the store. Nothing that helps
I tried looking for settings but I can only find old threads that refer to calibration, so I assume that this function no longer exist.
I used the servicemenu but cannot find any calibration there.
I reinstalled the phone as well (factory default) + safe mode and I googled for hours.
The tool I am looking for is a tool that ask to put your finger on dots all over the screen and that it then generates some setting file that the operating system uses. No idea if such a program exists?
If someone has an idea, please let me know
The phone is not rooted but if needed I want to do this.
ps. feeling sad about this happening again. The phone is not even a year old.
My old Z2 broke as well... I wish that they go back to plastic..like the good old Xperia Arc S. I dropped that phone hundreds of times
greetings,
Demesmaeker
