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 ?

Any help much appreciated....I have an issue with my screen flickering, dimming very faint and going black when i touch my screen. sometimes my screen will go black for long periods of time and phone is practically useless. This is not an issue of just a slight flicker on light colored screens that I have read other people describe. The screen does not always do this but is definitely getting more frequent. The flickering/dimming happens when I touch screen and especially when I touch it with more pressure. It also seems to be more sensitive on the bottom half of the screen.
I consider myself as the "scientific type" and have been testing many different scenarios trying to find a rhyme or reason to this happening. The only thing I have found is that if I keep my phone out of my pocket the problem seem to not happen. Then I can put my phone in my pocket for as little as 5 minutes and my screen could be messed up for hours. Everything else about phone seems to work great.
At first I was thinking this was a software issue but now I am leaning towards hardware? I am rooted, unlocked with s-on and cannot send back for warranty. I was running mean Rom for many versions and have also gone back to stock rom and stock kernel and experience same problem. Many reboots and clean installs too. I have also taken phone apart and reconnected all ribbon cables hoping there was a bad connection.
My Evo lte is only 4 months old and has never been dropped nor has it ever been wet. There are no scratches on screen and has been in otter box since the phone was brand new. I am running out of ideas and am I dire need for advice.
Thanks,
Mike
I thought it was only me upgrading P920 from GB to ICS and JB and got touch problems, but a quick google with "ics touch screen issues" reveals a lot. This problem seems well-spread across devices, ROMs, kernels,...
Basically the main problem is that it's harder to get the phone to register/recognize a touch/swipe. I sometimes have to touch/swipe multiple times for the action to happen. Sensitivity doesn't seem like a problem here, because a very light/soft touch can still be recognized. It's just that the screen often doesn't recognize the touch. Turning on pointer location in development options is the best proof. Try tapping the same spot on the screen lightly (as normal use) and some times it will register the touch, sometimes not. At first it seems like no problem but gradually becomes very itchy for everyday use. It's like using a defective product. But it is definitely NOT a hardware issue, because every time I revert back to good old GB (any version, any kernel) the touch screen just comes back alive. Every slightest touch and swipe registers beautifully, never misses.
So if your device does not suffer from this problem, lucky you. Us who are suffering from this, would like to have some cues on how to solve it.
NOTE: SGS touchscreen booster DOES NOT solve this issue. It's a great tool, though, to increase the touch sensitivity. But as this is not about sensitivity, it's useless for me.
So anyone have a solution? Thanks in advance!!!
So I have had my ZU for almost two weeks now and loving it, however something has started to get on my nerves and I'm afraid I have something wrong with my phone. I know I shouldn't get so nitpicky but I spent heaps of my hard earned student cash on this phone and I want it to be running smoothly!
Anyway, from about day three of having my phone I started noticing erratic screen behaviour like phantom screen input - as though when the screen of any regular phone has water droplets on the screen and the screen goes haywire, however in my case the screen is completely dry? It usually goes away after I lock the screen but it gets rather annoying when I am typing a text and then all of a sudden all these random keys and words start being typed (and not by me!), so I would like to know has anyone encountered this problem?
My phone is stock rom and has not been rooted. I don't have a screen protector nor have I used any other styli other than my fingers.
My phone is bone dry and I live in summery Australia so air humidity can't be a factor. And I'm pretty sure there's no ghosts in my house!
On the current build .136
What should I do? Is this a faulty screen? I have checked other topics regarding this and my issue doesn't involve any lag or latency between from my own keystrokes than to those done by screen.

Build 290 and 136 got rid of this problem for most users. Give the screen a good clean
You could also search for a thread by hamdogg (or at least he commented on it) about a edit in the system to lower the touchpanel sensitivity - but will need root.
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.

I sometimes hae the same issue, screen just doesn't respond?:cyclops:
Hello mates.
I've got some issue with my desire x touch screen. It is becoming unresponsive.
The whole thing started like 1 month ago. I've noticed that as my phone gets hotter (playing games, using internet) my touchscreen was slowly becoming unresponsive. Firstly I was unable to scroll down my notifications (only the narrow bar at the top was not working) and then it came to a random places of screen, so I couldn't even write sms message. The thing is that it is not unresponsive at all. When I press certain unresponsive area it finally detects the touch. I tried everything, from wiping my screen with a soft tissue through removing battery and sim and sd card to wiping dalvik and cache. I've noticed, that after night the problem was almost gone. And again, after using phone for some time issue occured again. I figured that flashing a new kernel might be a good solution. And it helped and I was happy.
Unfortunatelly, yesterday problem returned. But as you probably suppose - flashing kernel ain't helping. I've also tried other methods mentioned above, but the only thing what helps a bit is leaving the phone unused for like 1 hour or so.
Do u guys have any ideas, what can I do to repair it or to fix it? Any help will be strongly appreciated

I have a similar problem after replacing touch screen. I have found the source of the issue, it could be similar to yours.
My touch screen at the bottom was glued to the LCD in a short line and the adhesive was probably touching part of the LCD cable that goes underneath. I used a hair drier to warm it up and lift off the touch screen. That way there is no bad interaction between the touch screen and the LCD. Haven't had this problem since but my touch screen is unfortunately a bit lose this way. Even now, whenever I push the navigation part of the touch screen too hard, the problem comes back. I will need something to isolate the bottom part of the touch screen from touching the LCD. I will keep you updated if I find a final solution. In the meantime, it could be worth trying it on your phone too.
I think I will just get S-OFF, revert my phone to stock and give it back for warranty repair Anyone of you guys did this? Did 7 vibrations at boot void your warranty?
I'm thinking about warranty repair, cause my bro has the same phone, but full stock, not even rooted. And he got simmilar problem to me, but with less intensivity (it just comes and goes once in a while). Also recently I got this phantom touch problem (after enabling show touch in options I saw my phone is detecting some touches in specific areas) So I think warranty will be the only option :/
