Hello,
my Spica is having this issue: (video: http://www.youtube.com/watch?v=pdAtIBHYrAU)
after I unlock it I basically get one only chance to use the touchscreen and after it becomes insensitive.
It does not seem to be an hardware issue, but at the same time it does not make sense that there would be some software mulfaunction as I have just installed a fresh new rom.
Have you ever seen anything like this or are you familiar with this problem?
Thank you for your help.
Use hw keys to do factory reset, it may helps.
I kinda had this problem when the usb/charger is plugged in ..........is that the issue ?
unplug it
that's normal. You charger is not good stabilised, so some mV upside do this.

Hello
Im the happy owner of an HTC Magic by TIM (Italian Operator, and its a 32a model) since a few days.
Anyway, i noticed a little problem that is really annoying. Basically, when the phone is plugged to its USB or AC charger, the touchscreen sensitivity is greater than when its not. It recognizes every little touch on the screen.
Instead, whenever i unplug it, the touchscreen needs me to use the whole finger just to let it recognizes the touches.
Is that normal? Could it be a problem of the rom made by TIM? or is my device bugged?
Thanks in advance
I think it's because of better grounding when connected to the computer through USB (as the computer is connected to ground too. The same thing happened with the Iphone. So I think that's the way it is... But I rather don't have any problems with touch response ( I've noticed that touch sensitivity on the edges is worse..)
The point is that when the phone is plugged, it works as good as the iphone, a soft touch get recognized.
When it is unplugged, i gotta use the whole finger or it wont even fairly recognize it.
I tried to flash the cyanogen 4.0.4 port for 32a and the situation is still the same, most likely my device is bugged.
Gotta Restore/Wipe the phone and im getting it back to the shop
Anyway thx for the help
just recently with the new froyo roms my 32b magic is having problems, everything works great except i cant long press to say drag a widget to the bin, it just selects the quick touch action. its not always like this but when it is its really anoying, it happens with multiple roms, so i think it may be an app causing the problem, anyone else have this problem
UPDATE:
figured it out, for some reason this problem is happening when i am plugged into the charger its all very strange
it looks like you have similar problem as I have

does it happen only when you have phone plugged in charger, or also to USB in computer?
and what happens when yuo slide keyboard?
Hello all. Sorry to post about this, but I see it's a somewhat common issue with some other 'Droids and figured I'd toss this in here to see if anyone else has had any issues.
Basically, whenever a USB cable is plugged into my computer and the phone, the screen stops responding properly. I've heard this could be a kernel issue?
Any suggestions?
not sure, its it fully unresponsive? I have minor issues with it not working for time to time but it will come around. This is both on and off USB. I just wiped everything and reinstalled super clean 1.0 and that fixed it, I also installed only apps I need and none are on SD as I think SD is not so responsive in this leak. My gallery app takes forever to load and I have a class 6 SD card.
I'm using RubikS' ROm of Froyo and just pluged my phone into my computer and the gui and all touch elements are working without issue. What version of Froyo are you using?

I notice this when I'm charging the phone, I just avoid having to use it while it's plugged in.
I have my phone pluged in at work to my laptop all the time and have never seen an issue with the touch screen.
Not all USB power connections are the same
I have the USB provided with my fascinate. In addition, I have a cheap power only mini-USB connector. When I use the latter, on any ROM, I find the touch screen to be non responsive. When I use the stock power it works. Just a FYI, so please check your power cord first.
I'm using the stock cable that came with my phone (of which I picked up this last Saturday).
Right now, I'm running the Blackhole ROM, it happens quite often, but there are a few instances where the touchscreen does work fine. It seems to happen mostly whenever the screen goes to sleep and requires an unlock.
I don't think it could be the Blackhole rom, as it would have been more widely reported... could it be? I have absolutely no issues otherwise with it (Except pressing the redial button crashes the dialer and hitting "Setup Wizard" in the options causes an exception/FC)
this has always happened to me, i think its just an electric interference from the charger to the screen. a better cable might fix the problem but i'm not positive on that, just conjecture
Don't use 3rd party chargers/ cables, this is a known issue to messing up the touchscreen. Also hold your phone while you use it, you need to do this because it seems to ground the phone and make it responsive. I have tested this on a few phones and they do not like it when you touch the screen while you are not holding it.
Hello,
Yesterday my rooted LG v20 h990ds got a kernel crash (green screen). I pulled the battery and after that I noticed no difference.
Today I woke up and noticed that the phone was really slow. Somehow the touchscreen was not always responsive so I had to lock and unlock it again.
I couldn't figure out what it was and I thought that maybe it was caused by the root. So I did a factory reset and went back to stock (LGUP). Unfortunately the problem is still there. Does anybody know what it is? Could it be a hardware defective?
Thanks in advance!
edit:
After a few tests it seems to be the digitizer. I've installed an app to test the digitizer.
Sometimes the screen sees a short touch as a long touch. That's why it opens extra options when I try to type a letter.
I've opened up the phone to see if there was any moisture damage visible, fortunately that was not the case.
Is it still possible that this is a software problem? Or do I have to buy a new screen?
edit 2:
The phone is functioning normally again. I disconnected the screen cable and plugged it back in again. Probably it was a loose contact.
This thread can be closed
So my touchscreen is acting really weird and I can't pinpoint exactly what the problem with it is. Im planning on just sending in the phone for repairs, but wanted to post here as a sort of "last-ditch effort" to see if there is anything else I can do.
I've already done a factory reset of my phone (and it seemed to work a little bit better) only to start acting up again like 10 minutes later. Safe mode doesn't resolve the issue. I can't swipe to unlock my phone and pressing once either doesn't work or registers as a long press. Everything is telling me this is a hardware issue, but it started happening randomly with no screen damage and there seems to be a pattern to when the touches register and when they don't, so it might be a software problem albeit a very weird one.
This is what the touchscreen input should look like: https://i.imgur.com/qhTNgq9.gif[/url]
This is what the touchscreen input actually looks like: https://i.imgur.com/DFtMVSz.gif[/url]
Any help is appreciated. Ask me anything, ill try to get back as soon as possible.
Also, if this is the wrong place to post this, please direct me to the correct place.
I think really the only thing you might be able to do is reinstall the firmware, if that still doesn't fix the issue then it probably is some sort of hardware issue
Things you can consider
- After a Factory reset, try using your phone without installing any "other" Apps except the ones from Google. / or / using it in Safe Mode ?
- I am sure you might have already tried removing the tempered glass
- Did you try the *#0*# and test Touch ?
