Hi all. My evos touchscreen is probably dying. Sometimes my screen goes crazy and doesnt react to touches. When I enable "visible" touches, one or more are visible on the bottom of screen. When I turn off and turn on display, everything is OK (sometimes not). Any solution? thx. ps.: i tried many roms.

Hi everybody,
Recently I've been encountering a problem where my streak won't respond to any touches after I open the screen. Pressing the power button and waking the phone up again does not solve the problem. I've read about the static issue, but unfortunately it doesn't seem to be the case here as the problem still occurs even when my streak isn't in my pocket.
Oddly enough, rebooting the phone solves the issue temporarily. The touchscreen will work perfectly until I turn the screen off again, but when I turn the screen back on, the phone doesn't seem to register any touches. The phone itself works fine as it still receives notifications even when the touchscreen is unresponsive.
Is this a hardware or a software issue?
I'm currently on DSC 2.2 and baseband 366. I'm going to try a factory reset right now to see if any will improve.
Thanks!
Edit: did a factory reset, problem is still occurring
I have the same problem, does anyone know how to fix this? thanks

Have you tried recalibrating your touch screen from the dell menu?
Its option 3, worked for me a few days ago.

Yeah I have. I'm currently assuming it's a hardware issue since I've reverted back to a stock rom along with several other custom roms but the touchscreen still remained unresponsive after waking it up. I'm hypothesizing its a bad connection somewhere, especially if the display and touch sensor wake up separately. Does anybody know anything about this and whether it can be repaired?
On the other hand, I might be completely wrong...
I noticed that some bags for DS5 produce static electricity, such as the original Dell Bag (Futon bag - ?)
The Leather Bag (with red fissure) does not produce static electricity even when having the DS5 in trousers.

I had this problem once, pried and screwed the Streak open, checked connection ribbons, and cleaned it with (a little bit) electric contact spray. This has saved my irresponsive power button as well! Success:good:
Hello. I have issue with the touchscreen on my X10. First of all this phone is already 3 years old, and I'm the second owner so problems might arise from age. But everything else works fine though.
Anyway, the issue with touchscreen is, when the screen get wet a bit (whether it's from sweat or moisture or something), the touch screen gets jumpy. It does respond to my touch, but it reacts to the different spot of the screen, making typing and scrolling impossible. Ghosting. Erratic. Something like that. Wiping the screen does solve the issue, but it's bothering. I've removed the screen film that came upon the phone, but it still happens. Shouldn't touchscreen phone respond touch well even if the screen is a bit moist?
Any help is always appreciated. Thanks before. :good:
I too have this problem, any solutions ?
Bump
Hey Guys,
I am having a big problem with my device. The touch is not working. I have been flashing various roms on my phone and after playing with many roms, i finally flashed stock rom into my phone and flashed a stock ics based rom. Everything was working fine until one day my touch was not working well. I switched off the phone and turned it on and the touch was right back on. Again, things were smooth until this issue happened quite frequently. The problem was solved after turning off the phone and powering it off. After some time, the problem again started to come. At this point, the touch was not working COMPLETELY.
I was scared and immedaitly flashed the stock rom. During the initial boot, everything was working fine. But, when i locked the screen and tried to use the phone after some time, the same problem occured again.
So friends, my question is, Is this a software related problem or a hardware related problem. If this is a h/w related problem, is there any point in touch working during some time and not working later? ( Now, touch stopeed working completely). Will any tutorial on this forum about bricked touchscreen (after flashing wrong rom, which i am sure i didn't) will help me solve this problem?
I am awaiting for your valued input as this is the phone that i use for all my communication needs.
Kindly help me
Thanks
Well, if stock didn't solve it, there's a chance it's a hw issue. If you look closely, "touchscreen brick" guides are meant for the mini and the lww (touch digitizer separated from display), not the mini pro (touch digitizer and display as one assembly).
And yes, there are situations where your touch digitizer might cease to function for a few seconds then respond after a while, and sometimes it stops working completely after the next reboot (or forever). It happened to me with a deffective replacement part.

Thanks for your reply.......
I guess it is indeed an hardware issue. My phone used to reboot when i slide my keyboard out fast. The screen gets dimmed out and the phone immediatly restarts. Last few days before the problem worsened it was overheating also.
Can you suggest me which hardware part i should change to rectify the touch issue? Awaiting for your reply
Thanks a lot
Ok your problem seems to be worse than expected. A faulty touchscreen shouldn't cause sudden reboots. I'd say it's a flex ribbon issue.
Try to get a replacement flex ribbon and test it extensively before installing it on your phone. Replacing the flex might be enough to solve all of your problems. If any of the problems persist with a new flex, you'll need a new screen assembly (quite expensive at 35~50 bucks).
Hi guys! One of the most annoying problem my smartphone has is that it does not always unlock from the first glide. I have to lock the screen back and try again. Also this thing happens when somebody calls me even though my hands are completely dry and there is no kind of moist on my touchscreen. I've tried 3 different type of rom's and still no solution. It might be a hardware problem?

type *#*#7378423#*#* in your dialer app, go to Service tests and Touch Screen
check if the screen responds to your touches.
If no then it is definitely a hardware problem
it definitely responds to my touches. This problem appears randomly only when it try to unlock the phone.
bump?
same here. no idea if its hard or software
any ideas? :crying:
Same issue, usually it happens when i turn on Mobile Data on slower speed. screen stops responding
do a full backup and flash another rom and give it a try.
I have a very irritating problem my device touch screen is responding even though it is black and locked. It keeps annoying me when i am in a call and it is only a matter of time till it ends the call. Problem started after having a screen replacement but i can hardly believe it is a screen problem because it is functioning normally and also gets dark when i am in a call. My proximity sensor is working as it should. It is like my screen gets dark and not totally off.
My phone is rooted and i am running lollipop 5.1.1 custom rom

It sounds like you are having ghost touch problem. This usually presents itself when you change the front glass with digitizer and leave the old LCD. This cannot be repaired if this is the case. I dont think this is a sw problem. When did this issue started to manifest itself? Right after the screen replacement or it started to appeare gradually?
Yes it appeared just after repairing the cracked screen. The lcd was working but not the touch and the glass was all cracked.
How can i solve this?

One thing to mention is that i do not get touches that i didn't make. They are just getting read when the screen shouldn't read them.

But does touch work normally when you use the phone? Ghost touch can manifest itself on various ways, like your case or can go completely crazy when the screen is on. You can try some apps that resolve ghost touch like touch fixer. Some people are saying that unlocking BL and flashing CM resolves this issue and other sollutions you can try is to apply heat with heat gun or hair drier directly on the screen to make sure the glue is sticking the digitizer onto the LCD propperly, or fiddle with the flat cable contacts bit by bit until the touch is working properly but this requires disassembling the device again. You can alway try to flash different firmware to see if it'll resolve your issue but I highly doubt it will. GL
