Touch issue - Lenovo ZUK Z2 (Plus) Questions & Answers

I am not sure if it is touch issue or display issue. https://www.youtube.com/watch?v=JdMbbML9ECg Please have a look at this link.
The touch works for 2 seconds of screen on. Anyone having same issue? Please reply if anyone has fixed this issue.

same problem.
It's like the smartphone, after a 2 second make a check then blocks the touch.
I noticed that if I touch the screen before turning on the smartphone, the touch does not hang after 2 seconds but after more than 2 minutes.
I'm not sure it's a hardware problem; I still believe that it can be solved by preventing the above control.

Which ROM and Kernel are you using? Should be a kernel related issue, try flashing a different ROM or Kernel.

I had the same. I used a piezoelectric of a lighter to give static shocks to the screen while touching it with the other finger. It worked.

I had the same issue, and fixed it by removing the screen protector. Now the touch has been working since yesterday

I am also facing the same problem on my phone.
I tried discharging the phone completely and charging again.
I use the original charger only.
I'm running Pixel Experience ROM on stock kernel. This problem started a week after unlocking and rooting my phone. I also feel that it is not a hardware issue.
The problem started with the nav. buttons: The rest of the screen functioned properly but the nav buttons were unresponsive. A little later (a few hours), the entire screen responded to touch intermittently, and after that it responded only a few seconds after unlocking the phone (the above mentioned problem).
I am having a very tough time as this is my daily driver and I'm stuck.
Please Help. Thanks a lot in advance.

This is exactly what has happened to me too. It started with the nav. buttons and then the rest of the screen. Have you found out what is to be done?

Guyz try a cell ,u know those 1.5 v cells use them as the s pen im not joking it really works u just try once

No solution whatsoever!! I just cannot believe this is a hardware problem. My screen works (most of the time) for 2mins if I wake the screen up while touching it with one of my fingers, otherwise the screen works only for 2 secs.
This problem has been discussed in very few places although there are many people who are affected. Loosing hope.
Can I exchange this phone on Filpkart/Amazon in India?

I exchanged my z2 plus with this problem on Amazon without any problem. They only want a phone which switches on and whose display is not cracked

Exactly how did you did that? Could you explain?

Broke a piezoelectric lighter and got the raw mechanism.
I made it discharge several times on the affected area while touching another area of the screen with another finger

Workaround
I tried one workaround indicated by someone else on another thread. Follow below steps
Press power button to put screen off
Hold phone in left hand and put left thumb on screen
Press power button to start screen
Touch with right hand fingers
It will work till left thumb is there on screen..
If touch is lost follow from step one
Atleast this helps alot instead of only 2-3secs stuff..
Thanks to one who indicated this workaround

Found a solution
Hi I was also facing this problem and I was ready to give up then I tried changing custom ROMs and when I installed the dot os v2.4,the problem disappeared and I was back to using the device normally
Hope this helps

[Q] Touchscreen stops working

Hi,
sometimes the touchscreen of my defy stops working (but the phone is not frozen)
and the only way to fix it is to lock/unlock the screen...
does anyone have the same problem (and can help me)?
thanks
P.S
i've had the problem both with stock rom (2.2) and with cyanogenmod rc 1.5
When this happens, do the 4 buttons below your display still give you haptic feedback (little vibration) or do they react not at all?
Also, does this only happen when there's the normal launcher/standby screen active or when there's an other app active too ?
Did you undervolt ?
Edit: Also, this seems to be a hardware problem which seems to be well known in a certain German android forum but I cannot find much about it in here. In short, the digitizer unit seems to be broken for some people and locking/unlocking helps because it disconnects and connects power for the digitizer. The people there fixed the problem by replacing the digitizer (which isn't easy at all!).
It would be nice to have someone from XDA who had this problem before too, to confirm this problem!
First of all, thank you for the answer
When I have the problem, 4 buttons stop working too.
It usually happens after a period of stand-by, i don't undervolt or have some other application running than the launcher (ADWlauncher).
I bought the phone one week ago, if it is an HW problem, i can't repair it by myself...
I'd recommend to wait and see whether xda has other suggestions for you and if not, just check the Motorola hotline and ask whether they know something and if they do change it for free.
Also, what you describe fits perfectly to what I've read elsewhere (don't know whether I'm allowed to post a link here or if it were useful at all because it is in German). So it sounds like your digitizer could really be defect.
ok, even if i hope to solve the problem by myself...
News: They've changed the touch screen, but the problem is still present...
Can it be a sw problem??
Keep sending it back, they will replace it in the end.

the whole phone?
Yes, the whole phone. They have two year warranties, but don't put up or make do, you should have a phone that works right

Touch panel trouble

Noticed something strange for the first time , screen is laggy and not responsive while charging the phone , I think it maybe is the kernel as its the first time to notice this , It happened after flashing franco-r6 kernel and iam using insert coin 6.3.1 Rom
Is this normal ?

You flashed a ROM, You're not stock therefore you need to consult the dev of that Rom about the issue.
To be fair, I had this issue on stock.. so it probably isn't a problem with the ROM

Yep I get this issue at times as well. Especially when I've left it to charge for a while and try to perform a pattern unlock. Happens about twice a week or so. Screen returns to normal after 10 seconds or so. Weird.
+1 this happens on stock roms all the time. it's intermittent, and often can be temporarily fixed by switching the screen off then on again.
I'm about to send my phone in for repair because of this problem. I actually have a dead patch on the screen which is intermittent. If I go to Developer Options > Pointer Location, and then trace my finger around the screen, I can see the patch where it's not picking up the input. Also sometimes the phone behaves erratically and can become completely unresponsive and flicks back and forth between home screens. Turning the screen off and then on again fixes it temporarily.

ZE550ML Random Ghost Touches ocasionally

Hi!
I Have a ZE550ML with stock rom in the last firmware version released and its not rooted... since nearly a month im facing some ghost touches randomly in the touchscreen... The phone and the touchscreen works perfectly but, sometimes, witouth an aparently reason, the screen becomes "crazy" and after activate "Show touches" in developer options, i can see the screen is being touched by... nothing? x'D
Anyone else is facing this issue? Can anyone help me? I've already contacted with Zenfone 2 support in beta forum but... no answer..
Thank you,
Regards
not getting that issue, even after several falls. must be hardware related.

Im not sure if it is a digitalizer problem (HW problem) because it happens randomly and not 2 much often.. (lets say, 1 time every 40 mins of screen) and after lock & unlock the phone, the problem its gone)

Software issue. What setup are you running currently and what have you tried?
Thanks for your reply. I have formatted the phone twice, removed the tamper glass but nothing happens. problem is still there.Downloaded Oreo 8.0 Ver 5.0.2 and installed the software but still problem is there.I think there's problem with Oreo update.some times I can't restart or switch off the mobile because of touch problem.
Please find my details and help me.

Same thing only it is with the bottom 1cm of my screen, it is intermitent except directly above home button where the screen more often doesn't work then it does...
I enabled touch tracking and when it goes wild the dots show up going left-right for about 2-5s and then it calms down, except for example when I get into E&A game when I click on a part directly beside home button I see two dots "spliting" my touch into 2 dots maybe 0,5cm left and right, then it usualy goes haywire.
I use US version of DASH charger with EU adapter but seriously doubt that can be the problem, I'm not the only one having it obviously and it seems most of us got it thru Oxygen OS (well I just bought mine, used and updated, about a week ago so...) and I'm really anoyed by this, a 300€ used phone having such a CRIPLING BUG!!!!

Mate 20 X Unresponsive Screen

Hello guys!
I have bought a brand new Mate 20 X just 3 days ago!
I noticed that some times I click something and it wont do anything or do it with delay and sometimes I click on something and it vibrates like it did it but nothing happened (like home button for example).
Does anyone else face this issue? do you know how to fix it?
Have a great day!
Nothing here, I also use the gestures so never use the home button. Is it specific apps that cause issues or just in general?

Yep, it happens to me quite frequently. I don't think it has anything to do with the screen though. Do you have a nano memory card? Are you stock? What apps have you installed? What browser do you use? Mine started doing it after the 192 update (I think) and has been doing it ever since whether I'm on stock or on a custom rom. You'll tap a program and see that it selected but sometimes it takes like five to ten seconds to open.

sometimes when I touch with 2 fingers to zoom (for example on a document) it just stays on zoom mode even when I touch with 1 finger (so when I try to move around it will change the size like a 2 fingers gesture).
scrolling is way slower than any other phone I tested, has anyone else noticed that?
Take screen protector off and clean it might be smudged . Maybe you could try glove mode it's more sensitive in settings

It's not a screen issue, it's a software issue.

tried both, didnt help.
I thought I was the only one with this issue.
After flashing the Resurrection Remix rom I have never encountered this problem.
I'll be going back to stock soon so I'll see if the problem still exists.
Mine works perfectly. Even with the protective film scratched. Worked perfectly with my previous screen protector, a tempered glass type. I have the chinese EVR-TL00 midnight blue model. Everything stock, no root.
I also have this problem
You're not alone, this is happening to me as well on the EVR-L29. In my experience it is most noticeable when tap typing and a letter I tapped on does not register. Also, once in a while when I tap on an app to open it nothing happens and I'll have to tap it again for it to open. It's a mild annoyance for me, but not to the point of ruining the experience. I'm hoping a future software update addresses this, unless it's hardware related. I love the phone, but this is probably my biggest gripe outside of the possibility of no future upgrades in Huawei's spat with the US.
