Touch becomes unresponsive few seconds after opening - Android Q&A, Help & Troubleshooting

I have a Lenovo z2 plus whose bootloader I recently unlocked, installed twrp, installed viper os (android - 7.1.2) and rooted it. whenever I try to use my phone (since the last evening) , the touch works for about 2 seconds and then stops working(every time) . I was thinking it might be a software/rom issue but when I close the Screen and before opening I keep my thumb at the portion near the front camera/speaker part pressed and then open the phone, then the touch works fine till I remove my thumb from there. When I remove my thumb, then again the touch stops working. Then to make the touch work for more than 2 sec again , I need to shut the screen off and do the thumb thing again. Due to this I'm thinking this might be a hardware issue but it were a hardware issue, then why does the touch stop working exactly about after 2 seconds without the thumb thing and touch starts working every time I open the screen with the thumb thing again till the time I remove it . And due to that timing thing it seems like it might be a software issue. All the other buttons are working perfectly. I really don't want the factory reset the phone till it's really necessary due to all the data and stuff. Can anyone please tell me what the problem is and how to fix it.
Thanks,
Manan

Are you able to fix now?

HI Manan,
Are you able to fix permanently? I tried to hold between speaker and front camera but not seeing that touch is working. Can you please share some pic pointing where exactly to touch? Also are you pressing hard or lightly? Please share how to do that?
Also later are you able to resolve the issue? Did you change digitizer etc. Did it worked normally? Please let me know.
Regards
Anil

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

As said in above post, please follow workaround if you are getting issue still.
For my case after couple of days, it started working normally. Sometimes that issue comes again, but i use workaround to use the phone.

I have the same issue! Please provide where you found this solution and workaround. Did you have to change screen?

[Q] Help! Problem with my Hero touch screen

I use my HTC Hero with careful and never drop it. Everything was just fine until 3 days ago, when I texted a message, i noticed that the screen didn't response with my finger. I touch on line on the top of keyboard ( Q-W-E-R-T-Y...) but all it response was Enter, Backspace, Space, Settings...( all the buttons at bottom ) and type automatically when I don't touch the screen anymore ( it just auto-type all the icon at the bottom). And it appear at least 5times each day. When I got this problem, I lock the screen and then unlock the screen, do that for 3-4times and that weird things disappeared.
I tried factory reset over 3 times and re-calibrate many times but it useless. My phone is using Official Rom and haven't rooted yet. Yesterday, i tried to rooted it and installed another Custom Rom to see whether this problem will be solved or not, but it still the same. Does anyone ever have this problem? Please help me.
Here's my video I recorded to let you see about this problem ( on the attach file - Sorry i'm newbie in this forum so that I can't embed a video I've uploaded on Youtube because it said that "To prevent spam to the forums, new users are not permitted to post outside links in their messages" )View attachment 443134

THanks, I've read it but all I saw in that thread is that people get issues about they cannot touch the bottom screen all the time, but for me-it still works, just get weird for sometimes, so I wonder if anyone knows how to fix it? Or let me know is it the software problem or hardware problem?
the main easy solution would be re-flash

Touchscreen problem

Hi. Touchscreen works perfectly, but it happens sometimes not responding or pressing automatically. When I lock and than unlock, touch works fine for a while.
I have rooted the phone and installed custom rom (X10S), but still the some problem. I tryed with Function Validation to test touch and it works great.
Is there a solution and what do you think, is software or hardware problem ?
well it could be something more simple then the touchscreen "not working"
as for it touching things you did not touch i get that from time to time when my hands or screen are wet,sweaty,greasy
for it not responding it could be that your phone just "freezes/hangs" from time to time.
best way to test this is going back to stock rom and testing it then .

touch screen problem

Dear memeber
i have a new problem with my htc legend its sometimes when i need to do something the touch screen give me a wrong selection and other times it not respond ,,, i do a restart for the phone and it back to work .. but i can't keep turn the phone off and re on it if somebody no how to fix this error its will be great and i keep the screen clean from everything i keep clean it but that is not help
Hello,
It happens too with my old ROM (B0.4.8), but didn't find the origin of the problem.
Sometimes it happens with my new ROM (CM9 Beta4) but only when I charge it (when by USB), as soon as I disconnect the cable, the phone is functionnal...
yeah but its not a problem with the room because i didn't do anything for the Os on it .. it just start like this sometimes it respond other times no .. if it work you have to made a selection many time or restart the phone
I experience it too. As I remembered after installing HomICS Venus this problem occur. I do not know whether its ROM related or not. I tried to flash another ROM ex. BlaYO ROM and CRQ 1.3 but the problems still persist.
I had this problem too - sent it to HTC and they exchanged my Legend for a new one ----- as I heared it is a common problem and has to do with the grounding of the touchscreen -> that is why it works sometimes and sometimes it doesnt
Sorry to say that I too suffer from this problem. Also, the part of my screen, where the power widget on the notification bar is resting, is completely unresponsive. I need to use the trackball to hit those buttons. And also, sometimes the screen can just go bananas and go into spasmic movements on its own. In my frustration once I hit the screen really hard with my knuckles and that temporarily fixed the spasmic movements. But it still reoccurs. I assume I would need my warranty to replace my phone, but my warranty has already ran out.
I can also confirm that it has NOTHING to do with your ROM. It started for me when I was running CyanogenMod 7.1, but I still have the same problems on stock ROM, HomICS, Miui, basically any ROM.

Sofkeys autopress !

1. Softkeys ( Menu and Home ) starting to auto-press today suddenly for no reason. Before you ask , I don't droped my phone or any type of shock !
2. After some time sofkeys ( Menu and Home ) stop working at all ! They don't even light out if I'm trying to press them... Although the 'Back' key is working perfectly fine.. :/
These problem solve magically after one restart but after few minutes they still persist ! Sometimes working fine , sometimes autopressing or not working at all and after a while working again.. :/
Anyone else had this problem too or know how to fix it ? ( if it's even possible to fix )
P.S. I don't think that's an Software problem , I think that's an Hardware problem tho...
EDIT : My 'Menu' and 'Home' buttons are officially dead now... R.I.P. !
I have the same problem... After updatee from 7.1.3 to 7.5.1 and to 8.0.1. I tried with custom ROM, with stop Tapatalk... But without success. I tried also with another launcher and they start to work for only 10 minutes.. tried also with wipe cache! This is very big problem

That's not a Software problem , that's a Hardware problem...
In my case all started yesterday... Menu and Home keys started to autopress/not working and until night they stopped working at all , completely dead ! That happened suddenly , I never had that problem or have dropped my phone , never !
Also I read that many Xiaomi have this problem including Redmi Note 3 and even Mi5
R.I.P. Soft keys !
Now they work again after whole day that they don't worked at all now suddenly starting to autopress again and works pressing them :/ They worked again ( including autopressing ) just for few minutes and then not working again..
I'm starting not to understand this device at all !

Acutally it's software problem... I'm sure because when i deinstall Taptalck updates, they start work correctly for around 15-40 minutes. After that they just died. After install new launcher (from Gplay) they start to work again. So im pretty sure that, this is software problem... But from MIUI dont care about our problems

I don't know... I'm using exactly the same apps like always , never had that problem ever with any ROM... Last night I flashed Stable 8.0.2.0 , they worked for few minutes and then dead again !
I still think that's an Hardware problem , but I really hope I'm wrong and you're right to be a Software problem..
If was harfwer problem, when we make clean instal, we sshould have the same problem without any reaction of the button...

Exactly same problem for me. Sometimes it start to work ( very rare ) or auto press but I disabled Menu and Home buttons because it's annoying to get out of app because autopress.. Have you tried to flash latest fastboot ROM ? If it's from software that should solve it..
Or this problem its in the kernel of Miui... I dont know, how to check. But i buy new display, and nie im waiting for it. When i change My display will text you

I thought buying new LCD too but it takes too long to deliver and I read some bad reviews about them : not original , dead pixels , crash during transport , etc. I'm thinking buying a new device maybe...
Anyway I'm really curious about your new LCD , so please tell me when it arrive and how it works :fingers-crossed:
Btw you bought just the LCD or LCD+frame ?

Only Display, i will text you when i finish with rhe display
I had the same problem. If you are using custom rom, you can activate on screen home button and disable softkeys, this may help for a while.
But it still will make some phantom touch on your screen. Finally I sent to repair and they changed another screen for me
Hello dear friend! I changed my display... And now everything is good. Buttons work properly. And I have good news for you. I just finished with one test: I put the old screen again on the phone and now the buttons work again... I just heating up the display when I was removed the old screen. U can try to heat up your phone on the button of the screen with hairdryer gently. Or just disassembly your phone and assembly again if u have any questions I'm here
@vetefan I already disabled Home and Menu buttons because it was really annoying to always get out of apps suddenly without pressing anything !
@ZinovievBG Hey mate ! Few weeks ago I opened my device to clear dust in front camera and also I cleared everything in it including a bit display stuff ( you can't really clean too much display because it's one piece ). I'll try heating soft buttons with hairdryer and see if it works. One question : this heating solved the problem definitely or just for a temporary period ?
