Touch Issue with Lenovo Z2 plus - Lenovo ZUK Z2 (Plus) Guides, News, & Discussion

Hi
I am using lenovo Z2 plus an have been encountering problem with touch not working. The touch works for 1 second after unlocking the phone and then stops automatically. I have tried resetting the phone, installing new custom roms but in all cases touch works for some time after unlocking and then stops working. Any suggestions on what to do?

Hey guys, is there anyone who can suggest me what to do? Would really appreciate some help

I guess touch display is broken. I had the same problem after a slight drop. Screen was perfectly ok but touch was broken. I replaced the whole screen since it was easier method

I'm facing the same problem right now.
Is it working for you now? Help me fix this.

I had same problem. I found a temporary solution some where-
1. Lock phone screen.
2. Put your right thumb anywhere on screen and keep it there.
3. Now unlock your screen with right hand fingers, dont lift your left thumb from screen.
4. As long as your left thumb is on screen, it will respond normally, it ayou lift your left thumb, screen will freeze and you have to repeat all avobe steps.
I know this is very annoying, but something is better than nothing.
Well my phone screen touch worked normally itself within 1 month without any repair.

I'm not facing this problem anymore. But, touch doesn't work on top of the screen.
I did whatever you told, yet it doesn't work. Is there a solution for this?

infinity loop of screen alignment

Hi everyone! im new to the forum So Ello everyone))) I,v had my wizard fr a month now and it was fine untill screen alignment become bad so i press on button and button next to it opened. Because of this i have clicked on Screen Align to align the screen but it started to loop (( dont know why because touch screen it self works perfectly. So what i supposed to do to align my screen? im using my phone by keyboard now because i just cant press any button on screen because it needs alignment. THX to anyone who has read this.
The wizard doesn't like being kept in a pants pocket. If you press with your finger firmly, running it all around the edge of the screen, that might cure the temporary insanity. Otherwise, set it aside (not in your pocket) for several minutes and try again. I got a leather belt case for mine to cure this issue.
If I'm guessing right, the first problem was that the touchscreen seemed to be very weird, so you tried to re-align it, and it always fails.
noup the problem was that i have bought the phone about 3 weeks ago it was working but when i tried screen alignment it just started to loop. I pressed it about 50 times(them 5 crosses) i dont know what to do (( because screen alignment now is crap (to exit screen alignment i need to get off battery and put it back)

touch screen issues

Anyone else having their touch screen stop working property until they have to reboot? It's like it gets way off on where I'm actually clicking.
I have experienced that, but only after I had flashed the modaco rom. I basically returned to stock firmware this morning and am having to re-root my phone...
I have had a couple of occasions where it doesnt seem to respond correctly.
For me its like it looses the calibration, seemed to noticed it when the device is tilted horizontally.
reboot sorts it, only happened once or twice though.
If the phone is in your hand, make sure your other fingers aren't curling over the screen around the edges to much.
I noticed this happening, and backed my fingers off around the edge of the screen and it started working fine immediately.
I think the screen is just extra sensitive.
Curious if that helps.

I read somewhere (maybe on this forum even) that non-multi-touch systems have this problem. Have the same issue with my HTC Magic, but after a while you learn of a way to use the device single-handed while not touching the screen.
I dont know if this helps or not but I have no idea what you guys are talking about

The calibration problem (the screen registers a wrong spot than where you touched) comes up if you try to use a non-multi-touch phone single-handedly, so part of your palm (between the thumb and index fingers) touches the edge of the touch screen. Especially if you are trying to reach a top area of the screen while holding the phone with just that hand, likely some part of the palm touches the bottom of the screen.
If you want to try having the problem, you can touch the edge of the screen with a finger and try to click a link with another. It won't register the right spot.
Supposedly the problem should go away as soon as you lift that body part up from the screen.... so I don't know if this helps the OP or not.
same issue
http://forum.xda-developers.com/showthread.php?t=615711
does not look like its happening all the time. Ran few tests and still can't duplicate the problem in order to find the cause. so far this happened about 3-4 times on my phone.
i hope this gets resolved soon and that its not the touchscreen issue.

I've had this exact thing happen to me a few times. I notice the tip of a finger on the edge of the screen, move it, then it works fine right after. Sometimes happens with the base of my thumb hitting the bottom left corner too.
Just make sure you're not accidentally touching any of the touch area and it'll work fine.
same here
i have just created new thread, this one wasnt here when i first looked http://forum.xda-developers.com/showthread.php?t=616418

Touch Screen Stops Working

I have had this same issue on my G1 as well a N1. This problem only happens from time to time, as happes with stock ROMs and custom ROMs.
For the N1, I was initial pulling the battery; however, I have found that if I hold the power button down (don't let go) and then touch the screen to unlock or power if off.
I have a friend with the Eris who was having the same problem; Verizon released a patch earlier in the week that seems to have solved the problem for him.

You can perform a soft reset on the Nexus One by holding volume down, the trackball, and pressing the Power button on top. A half second later, your phone will reboot.
I am also having these touch screen problems, and I can confirm I am not touching any other part of the screen to have it interfere with the non-touch-screen interface. I been testing with what people has been saying on here with having any other part of the screen being pressed, so I have been testing it out and I can say its a different response then what I'm experiencing.
Here is what is going on with my nexus one:
1) it happens at random times (my device is on my table and I am pressing buttons with one finger)
2) it only affects the bottom-left portion of the screen when it happens, touching everywhere else is fine
3) it thinks I'm pressing an area around the soft keys, an example is if I press 'A' it thinks I press either the '?123' or the 'back' button, same if I press 'd' it thinks I'm pressing the 'menu' button.
I can conclude that since not all nexus one owners has this problem it is a device issue, which what is going on is probably the same as if someone was accidentally pressing a part of the screen, but it could be part of the device is assembled incorrect or deformed. The physical form of my phone is off on the right side, I can feel the gray plastic part next to the black border next to the right of the screen is a little more raised then the left side.
But there is my experience with whats going on to me and my two cents.
Ive had this a little bit on my device as well, but I think it's a software issue since it went away when I pressed the home button.
edit:
Also it has happened exclusively in Dolphin browser
here too
Sporadically, it happens with my N1 as well. When pointing at the middle of the screen (in a list for example), the input registers 2 cm below my fingertip. Rebooting fixes this temporarily but it is annoying.
A SW update could perhaps cure this behaviour?

I just had this happen for the first time, all my presses were registering way below where i was touching, tilting into landscape in an app then back to portrait fixed it for me.
So now it happened to me too. I have the Nexus One for almost two weeks and I never had the unresponsive touchscreen. Of course I noticed that the center of the softbuttons is shifted upwards and that they don't register very well in the middle where they should and I had the problem before that the sms text input box didin't registered in the center so that the keyboard wasn't popping out but that is all only a problem of adjustment. Today in the morning after my phone was on standby over night I put in the charger to charge it and I got an email with pictures. I scrolled through the email and all of a sudden the screen became totally unresponsive. I tried to scroll and the screen registered at a complete different place. All of a sudden the email was gone because the phone registered the delete button even though I never pressed it. I could close the gmail program but I had a hard time to scroll between the home screens and the live wallpaper became unresponsive too. I decided to do a restart but I had a hard time to press the shutting down button because it was unresponsive too. This all happened not after heavily usage of the phone but after maybe 1 minute usage.
I am sure that I didn't touch another part of the screen when this occured because I realized before already that the screen becomes wacky if you touch it at two different places (lack of multitouch, so stupid to disable it). I hope that this is a software issue too. I can live at the moment with the 3G problem because it doesn't stop me from using the phone. The unresponsive touchscreen scares me more because because it becomes completely unusable.
i've noticed this with low battery. Twice its happened to me, the first time was when i first recieved the handset. and secondly was this morning when my phone was off with no battery again.
anybody want to leave their battery to empty out and try test if this is correct?
I've had this happen a few times in the ten days i've had the phone. I always make sure I'm not double dipping on the screen, and its easy to do since it will exhibit this behavior for a few minutes.
In my experience battery level has no effect on it.
A reboot always fixes the issue.
I figure it's software based.

My touch screen has been freezing up alot

. When I'm in an app my touch screen will freeze, no input works but my screen rotation does. When I rotate my screen my input will work again or if I wait about 30 sec or more the input will unfreeze by itself. This is happening alot and its really irritating me. I have an unlocked unit (from the store) rooted. I tried to "fix permissions" but ROM manager says "an error occurred while attempting to run privileged command".
Also I cannot sync with Kies (latest) and cannot sync with Samsung account in the "account sync" in system. Any ideas and thought are helpful. Thanks.
Are you by any chance touching the screen with your other hand? I've done that a couple of times by mistake, and that will prevent the touch screen from recognizing other touches. You can touch the bezel, but not the screen itself. One reason the screen might work adter rotation is that you are moving your hands as you turn the screen. If this is not the case, please disregard my comment.

I don't think I understand. I hold the bezel with my left hand. So you think that my left hand (the one holding the bezel) is being recognized without my knowing and this is not letting my right hand inputs get recognized? Hmmmm I will have to see this, makes sense because sometimes I get a pop up menu because my left hand thumb has accidentally touched the screen. Thanks, I will keep this in mind.

Yes I believe you are right. I have been very very careful of my holding hand and I have not had the problem. Thanks.

[HELP] Unresponsive band of screen on D800 stock Lollipop.

Hi guys, I have experienced a number of screen relates issues on my D800 since the Lollipop upgrade. I am pure stock, took the upgrade OTA from ATT.
1. Knock on stopped working. Knock off works OK. I tried all of the suggestions online, update touch firmware, etc. but still no help. This is no big deal since I can use the back button to wake up the phone.
2. I noticed scrolling was unresponsive in Chrome but ignored it because I thought it might be me.
3. I was out and on the phone and I noticed I could not hear her well all of a sudden and then the call got disconnected. I tried to put my PIN in to unlock the phone but that area of the screen was totally unresponsive to touch. I could enter the numbers in the second row of the grid but there is a 1 in my pin and that would not register. I restarted a bunch of times which I had to do only with buttons because I could not click 'OK' on the screen to confirm the restart. I got a screen on the phone saying my screen was unresponsive and this is how to answer calls only with the buttons etc.
I got home and used by OTG mouse connection to enter my pin and navigate the phone. I did a factory reset which I had never done before. The responsiveness seems better now. There seems to be one section of the screen that is unresponsive, right near the middle. I can't click on any of the icons in the second row from the bottom. I can get to the notification shade which I don't think I could do before.
I am attaching an image of a memo where I just ran my finger up and down the screen without lifting it. You can see the dead area.
Has anyone had this problem or knows of any solution? Thanks very much.

Pixel 4 display working but no touch

Hello everybody,
I have a accidentally cracked Pixel 4. The Display cracks after it falls from around one meter height. I decided to fix the screen and buy a new one. It seems to be not an original Bit the board of the new and the old screen seems to be exactly the same. I opened the phone and replace the screen without any damage. After the screen was inserted I test it if it woks. Success! Everything works (I not tested the touch Funktion yet) after I build most of the things together I give it another try and I recognized that the touch Funktion does not work. No matter how hard I press or hold the connector down etc. I tried many things also a Hard Reset. I never seen such problem before. And my question is: is this the screen, the phone or a software problem? And how I can fix this issue? I am completely confused because I fixed many phones but something like this is new. Regularly the complete Amoled does not work.
If I go to the left upper corner, there is some movement in the screen and this also stays if I release my finger (video).
