[Q] Spastic touch screen - Optimus One, P500, V General

My touchscreen has been doing some weird things for a while now. First of all it just stops responding altogether and a temporary fix is locking and unlocking the phone. The second issue is the screen taking a mind of its own and pressing itself to which I can only watch and hope that it stops. I thought these two problems were software related but I've flashed a few roms and kernels and have factory reset the phone too, yet they still exist. So does anyone have any solutions or has had similar problems? The annoying thing is that the issues happen on and off so there's no solid way of showing it to my carrier so they can give me a replacement phone.

I had the same issue, only while charging my phone. Seems like another bug or something

try wiping the phone's surface with very slightly damp cloth, it could be the dust & water causing all sorts of problems. make sure its clean. If it continues, contact the LG service. they MUST fix that kind of error. but get rid of your root

It's a hardware problem (touch screen)
I had exactly the same problem. I've sent the phone in for repair and had the touch screen replaced. Now everything is working fine.

Bottom 4 Buttons Dont respond

For about a week now, I've been having problems with the bottom 4 buttons not working. They seem to only work sometimes, if I turn off the screen and turn it back on they respond once or twice and then stop responding again. Is it hardware related, or some software setting that got screwed up. I've got the warranty, but really dont want to be without my phone for 2-3 days while BBY fixes it? Any thoughts guys? Thanks.
I had the same issue and it turned out to be the digitizer. Hopefully your issue is software related and can be fixed. Have you tried clearing data and the usual?
Yep, I've done everything short of a factory reset. Even tried a new rom. Nothing.
I'm trying to hold off until the One X or similar phone in June, and just upgrade, but its really pissing me off, and i might just have to succumb and take it to be repaired.

[Q] Touchscreen wakeup issue

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:

[Q] Another Digitizer Thread or Maybe Different One

Hi, I have a quick question.
My digitizer starts failing. I know in the end it should fails cause most of them need to be replaced but maybe my problem is different.
Most of digitizers are stop working at all or only some parts of it. My digitizer is working fine but ONLY after turning on screen sometimes it's working like using it with wet fingers - it's crazy pointing everything without my control. After turn off and on screen it's working fine until next turning on.
I'm wondering can it be software problem?? I had similar problem in Defy+, leds under hardware keys stop lighting and before sending it on warranty I wiped it and now all working fine.
It's no problem for me to replace digitizer or wipe system but it would be good to know that it can be software problem before buying new digitizer.
Maybe you need to apply the raindrop fix. Been discussed already.
First, thaks for understanding what I mean. (Very poor english)
Second, this is exactly what I ment. I just copied tounchpad.cfg from http://forum.xda-developers.com/showthread.php?t=1467696 and all looks fine now. No mess up on multitouch. I hope it will stop messed up touch while turning on screen, need to test it for a while cause this issue isn't appears on each turning on but ocassionaly.
Anyway thanks for fix. You saved my time (3 hours on wiping and bulding new system) and money on new digitizer.
One more thing. I'm using this phone from few months and everything was ok. The problem appears few weeks ago. So if it is bug in rom it should appears just after I bought it, not after few months. Or maybe it's not factory bug but just error in touchpad.cfg??
Sorry for post under post but I have few more informations.
After testing few days raindrop fix the problem still exist. Fix helped but not fixed problem. Still after turning on screen touch is acting crazy but after first touch it stops and before applying fix it stops only after turning off screen and turning it on.
I reflashed full sbf stock Gingerbread, full wipe including internal memory and still the same problem.
Strange thing I observed is the problem appear only when WiFi is on and it's searching or trying to connect. When WiFi is off or it's connected to router the problem never appears and when I turn on screen and after that turn on WiFi everything is ok. Only when I'm turning screen with WiFi on screen touch acting like crazy.
Is there any chance to fix it or should I buy new digitizer??
Ok, I changed digitizer on warranty and now everything is okay. Funny thing is that I have unlocked bootloader and they changed my digitizer without any problems. Less funny is that they broke both sensors changing it and I had to send My Atrix to Motorola once more after two days to change flex. But now I hope it should be working fine.
So after all it had to be popular hardware problem.
Thred can be closed.

Unresponsive touch screen

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 :/

touchscreen not responding

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.
