Hello guys,
Around a week back, my MT3G slide touch screen got unresponsive for a while. I rebooted around 2-3 times and thankfully the touchscreen worked fine.
Now, I am getting this unresponsive touchscreen more often and I have to pull out the battery from the phone and turn it on again. The last time this happened I had to do this about 8-10 times before the touchscreen would respond. I have no problems with my keypad, 4 buttons or the trackpad, just the touchscreen
I also did a factory reset and erased all the data that I had on my phone and SD card.
EDIT : I just figured that the touchscreen sometimes starts working if you slide out the keypad. But once the keypad is slid back in, it's back to being unresponsive.
My phone is out of warranty so I can not get a replacement I think.
Does anyone know what could be the problem for such frequent touchscreen unresponsive behavior. After a couple of reboots, everything returns to normal.
Any ideas ? I would appreciate any help..
Thanks a lot...
you got a broken ribbon
Hi there,
Do you mean the slide rail flex cable or the digitizes flex cable ?
Thanks
flex ribbon cable
I would say it's the flex ribbon cable which connects the motherboard piece to the screen and home button piece. I've purchased several "broken" my touch 3g slides from ebay that had either the screen shift problem when the keyboard was slid out or screen that was unresponsive/wouldn't come on. Both problems were fixed by purchasing an inexpensive flex ribbon cable like item 170747702766 on ebay. I watched a video and followed along on youtube /watch?v=-jgFHuVWlig (stop at 7:27 and reverse the process). However, my most used mt3gs is now starting to have the screen shift problem again and needs a new cable... it didn't last as long as I had hoped.
Did you try any custom roms?. reflashing/updating the device?
I guess it must be some driver issue!..
i have the same problem.
Could you fix it?
Seems to be a common issue. I've described the process of replacing the flex ribbon cable here - it's not a rocket science. Or just bring the phone to a serviceman who will do the same (if you lucky enough he could even have a spare cable, but I'd advice you to have your own bought from ebay to be sure).

Thank you for the information but another questiion that I do have is where would one get a serviceman that would repair or help repair a phone, usually the technicians are attached to the different cellular carriers and if one dosen't have a contract with them they are not likely to help repair your phone even if it is for a fee. Do you know any serviceman?

A customer brought her G2 on simple mobile to me with this problem: The letter "A" wont work on portrait mode nor will the home key. I figured it was the digitizer so I replaced that with an OEM Replacement part and as soon as we booted back up the problem was still there. Could it be her OS is corrupt or possibly a warp in the case thats keeping the plate from contacting the faceplate. I'm rather stumped as I ran a logcat and I saw nothing out of the ordinary during normal input. Any help is appreciated.
Touch plate? I am confused to what you mean by this. I am not too familiar with the electronic construction of a digitizer so any info would be helpful.
The digitizer isn't coming in contact with the face plate I believe. (Sorry I used like three different words to describe the same thing in my previous post) Any tips on how to fix that would be great. I saw a video on youtube that stated a part where a heat gun would be used but I never came across a front panel (The part with "T-mobile" on it so I installed the digitizer and went along). I think I may have messed up.
i have the same problem, i dropped the phone, and the touch screen was broken, i replaced it but now the left side and home button arent worksing
ps the broken screen worked still also on the left side , did you find a solution ?
I have the same problem.
I believe it's the ribbon cable, not the Digitizer. The ribbon cables on this phone hangs between both screens and is fairly exposed at times.
I still have a couple weeks in my warranty to return it to HTC, but I can't get it to S-on. Unless I get S-on before warranty is up, I'm going to have to replace it myself.
Ribbon cables for this phone cost ~$30 on ebay. tell me if you fix it.
Any luck with this, anyone?
Last night I stepped on my phone, not hard just accidentally put some weight on it. After that when I turned it on the screen illuminates but stays black. Everything else works, the touch screen seems to be working fine I can even make calls if I guess what I'm pressing.
My question is, do I need to replace the LCD screen, or would the ribbon cable be the problem. I took the phone apart and it looks like the LCD has its own plug.
Did anybody else have this problem? And any suggestions on how I should fix it?
Really no way to tell until you start replacing things.
1st, make sure all the cables are firmly seated, then try to power it up.
If still no LCD, then try replacing the least expensive part, the ribbon cable, first.
If it still doesn't work with a new ribbon cable, then try a new screen...
I unplugged, and re plugged all the connections and started the phone up, still nothing. Im thinking about going for the lcd replacement first since its just under $30 and is a much simpler install than the ribbon calbe. Also Most places will do returns so if the screen does nothing for me I can return it and go for the ribbon calbe.
Replacement for under $30? Where do you live? In The Netherlands it is a bit more expensive.
is it possible that it can just be a software issue?
noticed that my touchscreen is becoming unresponsive lately so i thought that changing the multitouch might solve it. the thing is, after selecting 4 touch, touchscreen becomes totally unresponsive. i tried wipe and even flashing stock os but touchscreen is still the same.
did i screw up my touch screen? how will i know? any known repairs or fix.
thanks
Sounds like your digitalizer (the glass above the screen) is busted and needs replacement. If your phone is under warranty, claim it, if not - get a new digitalizer and if you can't change it yourself, take it to a repair shop.
Changed the digitizer but still no response
Got a headache? It's all in your head!!!
switch ROM
You said that you flashed back to stock, but how about flashing to another ROM, I mean one that has a completly diferent multitouch enabler... that might work.

i was able to flash stock and it means i have no root nor recovery. and adb debugging is not enabled. i am out of ideas how i will be able to solve this.
After flashing stock ROM do you face the same issue with a new Digitizer?
yes. doesnt respond to anything except volume and power. even the 4 touch buttons doesn't work. i was thinking that i have received a bad digitizer or it is a motherboard issue. with the latter i have no idea how to check

I had recently taken my Defy to a service center. I just wanted to change the earpiece and the side casing. While replacing the side casing (while removing the Digitizer) they damaged the digitizer. The main touch portion was working but the 4 soft keys were not. They replaced the digitizer and everything was fine again (had to pay for it )
If you can carefully handle the phone, you can open up the casing and try reconnecting the digitizer to the board. (Do not remove the digitizer from the casing only reconnect the cable).
Replacement is better done by a service center as it requires careful handing.
I did open the phone, removed and reconnected the cable, still the same. also tried 2 new digitizer still the same result. I guess it us the mother board . Any ideas where to get replacement board ?
Thanks

i have got the same problem like you and i have solved it.
Do compass calibration like spin the phone 3 times in flat condition (laying down face up), then have the phone standing up and rotate 3 times, then on one side, rotate 3 times and then move your defy in the shape of number "8" in the air. Re-open the screen. it is suppose to bring back your screen work like it was nothing happened.
only for my defy i've tried never did this for another but from what i see you have nothing to lose here
Tried the calibrating thing and also a new digitizer. doesn't work. So it is the motherboard.
Anyone knows where to get mother board
Got a headache? It's all in your head!!!
Getting a new board is like getting a new phone - new IMEI, price for the board should be very similar to the pricw for a new phone too. If you think about it, it IS the phone. What's there in the phone other than the board a screen and a digitizer...
Guess you're right.

Hi everyone.
After a sudden heavy rain, I got some water in my Gnex. I tried the old bag of rice trick, only to find out the USB port was not functioning any more, neither for PC connectivity, nor for charging.
Following the advice of a person I no longer consider my friend, I tried spraying some Isoprpyl Alcohol in the USB port. It did get it to work correctly, but it damaged the digitizer, meaning I get random touches on the lower part of the screen (where the Back, Home and Recent apps buttons are).
I took the phone to a service centre where they tried to clean it, but the issue remains. I'll go there today with my wife's phone to see if it's indeed a touchscreen issue or a motherboard issue. I'm not sure if I want to invest in a new screen (over $100 + maybe a new back cover since the current one has quite a few scratches and cracks) and I'm thinking of maybe upgrading to a Nexus 5 or Xperia Z (the latter being waterproof).
The question now would be, could I do something with the hardware? Like, root it, connect it to my wifi and use it as a web server, or connect it to my TV through an MHL adapter and get a "smart TV". Can I get it to ignore touches on the screen completely, and only accept an OTG/bluetooth mouse input?
Any idea is welcome

One day I got caught in a storm having my Gnex in my pocket. Vacuum and rice tricks didn't work completely, as the phone was working properly besides recognizing the sim card (Mboard issue). What I did was buy a broken screen nexus off of Ebay, and exchanged the screens.
Now I have a fully working mobile phone, plus an MHL connected - XBMC enabled smart TV box, connected with bluetooth mouse/keyboard.
Question: Why would you need to ignore touches on the screen?
As I said, after spraying the USB port with isopropyl alcohol, it appears to have touches all over the bottom part of the screen, as if someone was constantly keeping 3-4 finger and touching away at the soft buttons. Cleaning the phone in a service centre did not help.

Sorry, I missed that info. Try searching for 'touch blocker' in Google Play. Don't know if that would work on a Gnex though.
Another (hardcore) idea would be to disconnect the screen altogether.
I'm adding this thread to document my recent findings, in hopes that it may help others recover from similar issues.
I dropped my ZenFone 2 (ZE551ML) on the kitchen floor the other day. When I picked it up, it was stuck in Asus Cover Mode, even though I don't have an Asus Cover. I was unable to get into the phone, so I forced a hard-reboot. After playing with it for a few minutes, I was able to get the home screen, though Cover Mode would intermittently kick on and off every few seconds. I got into the settings and disabled Cover Mode, but I soon realized that I had lost vibrate and haptic feedback functionality.
I took apart the phone to inspect for internal damage, and I noticed a small hairline crack on the flex cable connector that resides on the charger port board (see attached photo for details). The now-broken connector allowed the flex cable to shift laterally from its original position, leading to connectivity issues and causing the problems noted above. I was able to temporarily fix it by disconnecting the flex cable and reconnecting it to its intended position. As a permanent fix, I ordered a new charger port board from a vendor on AliExpress that ran me about $5 USD. I just installed it yesterday, and it seems to work as well as the original.

May I know how you played with your phone to go to the homescreen? I had the same situation but mine is vibrating. I'm just stucked on cover mode.
I hit it against me hands a few times. It seemed to be enough to allow intermittent access to the home screen and settings.
If your device is still under warranty, my recommendation for you is to let Asus repair it. I purchased my ZenFone with a broken screen and repaired it, so I have no warranty coverage. That said, I'd be willing to bet that you can't fix this without taking the phone apart. If I were you, I'd open up the phone, disconnect the battery from the motherboard and the flex cable, antenna, and vibrator from the charge port board, and inspect for damage. If everything looks good, reconnect everything, reassemble it, and try it out.

Glad I could help!
I got the same problem this morning. Tried the strong magnet mtd recommended in the asus forum but it didn't help. In the end, I found that by removing the cover, and then using your finger to flick on the magnet sensor (near the back button, bottom left of screen) works! After exiting the cover mode, quickly go to settings to disable it.
Thanks a lot
I had a similar problem , but my connector have gotten wet, and wasn't broken. When i cleaned it, the mobile got out from cover mode
