lockbot break touchscreen?

Hello all, im still having issues with my touchscreen being i guess mapped incorrectly or sometimes hardly working at all. The more i think about it the more i have to think it can be fixed and also i think about anything that could have happened to the phone b4 it started acting up and there was nothing, not a drop or hit. The only thing i can put on the same timeline is right after i installed lockbot is when it started acting up, is this by chance only or is there a chance lockbot modifies a file that could affect the touchscreen? Any help with this or even ideas would be great. Thanks, veritas
Ps...also after searching google for a few days i noticed a good bit of people posting that they had diff issues after installing a couple diff lockscreen apps, the only issue is that they are all only open post with zero responses to point in the right direction. Thanks

This happened to me too after installing lockbot.
I'm gonna try to reinstall the firmware and will get back with the result.
Currently it just comes and goes .. mostrly comes.. The bottom part of the screen doesn't work at all, and the sliding seems to work harder. Also, when I type a message in landscape, I press a key, and another one is actually shown to be pressed.
I also tryed different versions of lockbot, 1.8 and 1.13 before the touchscreen sarted to have problems, but when it actually happened, I had version 1.8 installed and it froze when I was using it.

Just reinstalled originial firmware, and problem didn't go away.. this is starting to get serious..

i seriously doubt it's related to lockbot. many people use it with no issue.

yeah.. lockbot might have been a coincidence.. I realized that I was using a different charger (not the original one) when using the phone when this problem appeared, and this seems to be consistent with the problem.
Actually I was charging the phone from the usb port of the computer, using also an USB extender.
I'll take the phone to waranty .. I tryed removing the battery and not using it for a day, leaving it to use up all the battery.. no success.
I think that there may be some wild static running through the phone from when I charged it off the usb.
If I play with the phone a lot now, sometimes the bottom part works bot not the top part.. and sometimes, I can press something on the screen just by hovering the thumb over it.

I'm getting the same problem! I press at the bottom of the screen and it selects something in the middle or nothing at all and at the home screen I won't even touch the scrren just hover my thumb over and the screen responds like its trying to go to the next screen but then gets stuck in the middle.
I called t mobile and they said to soft reset or hard reset, did both and no fix.

It's definetly a hardware issue.. it's sad that these touchscreens are so sensitive to the charging currents..
I would have imagined that they would have added some protection for this ..
btw, it's not just a htc hero problem, the web is full with all types of touchscreen phones being afected when using non original charger.

That's ALL T-Mobile knows how to do. Reboot your phone or reset your phone. If that doesn't work, they tell you its broke. Anyone could do that job.

ANY phone gets affected when using a different charger. People don't stop and look at the voltage of the new charger and leave their phone on it for 10 hours even though it's charged.
You can't protect from stupidity. Not saying any of YOU are stupid, but seriously, don't give your phone 100 volts when its made to receive 12.

I quess that ppl that use non-original chargers would read the voltage output..
Like I said above.. I just used the usb port from the computer to charge, if this is wrong, maibe they should have disabled it

I was saying here that other parts of the phone are just fine.. if there is a problem with the charger, why doesn't the whole thing brake.

long press problem

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?

(Froyo) Touchscreen not responding when plugged into computer's USB

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.

Keyboard Slide Reboots Phone

Hiya!
I've had my Quantum (C900B) for a few weeks now and everything's been great, but I have one strange little problem which I only started noticing at the beginning of the week:
Whenever I slide out or back the keyboard too quickly, the phone turns off and restarts (the screen goes black and the LG logo pops up and the phone restarts, no data lost). A little slower, though, and everything works fine.
I don't know if this is a red herring, but I first noticed the problem this week, after I had hacked Mango onto the phone. Of course, I had had Mango before (which I had to flash to the original ROM in hopes of resolving a SIM issue which ended up having nothing to do with that) and had no problem with the keyboard.
The resolution of the problem isn't urgent (I'll just avoid opening the keyboard full speed ahead), but I would like to know what is causing it and if this has also happened to you.
Cheers and thanks for the help!
-Aylmer, QC

Don't see what speed has to do with it... I would have thought hardware and the mango flash was just incidental...
Flash back to a nodo or oem rom and see if it still happens... Cause if it does it'll be a warranty job...

Actually, it looks like it was just the low battery... I charged it up and it doesn't reset any more, no matter how hard I slide the keyboard out!
Well, now we know, but still don't understand.
Thanks for replying!

[Q] LE E900 Unbranded AT&T USA touchscreen NOT responding! PLEASE HELP!!

I really like my LG E900 phone. I bought it for AT&T in the USA unlocked on Amazon. Installed Mango recently with all the firmware upodates and until today been having a lot of fun with my phone!
All of a sudden today, the touch screen seems un-responsive. The touch screen works intermitently. It starts to work then stops again. I have tried resetting the phone (have to pull battery). I wasn't doing anything when I this happended. I recently installed Tango and Livestrong mobile app, otherwise phone was flawless.
1. Is my touch screen broken?
2. Does anyone have a clue. I thought maybe the phone is running apps in backround but I can't seem to find the problem. The battery seems to drain also.
3. The phone does become operation for minutes at a time but then goes bad.
I wanted to add that the screen is also very slow at first then starts to respond normally. Almost seems to something happening in the backround. As of now, the screen is still not responding. If I continue to play with the screen, sometimes the screen starts to respond, but slowly.
thanks for help!!

In your position, I would try to:
1. Use the guaranty (if it's still active) and take it to a local service
2. Flash a different rom/firmware with all the latest updates inside and see what happens.
3. Buy a new e900...they cost less than ever nowadays...(almost 180€-190€ without a contract...)

You have got to be kidding me, the exact same thing is happening to me, and for 2 days now. I'm unbranded (I believe) on Vodafone Spain. The entire phone has become unresponsive. Drops nearly every call, has rebooted about 50 times in the last 24h.
fUnny thing is, it doesn't ever reboot when I'm actively using it, just during lock screen.
cOuld you further develop your symptoms just in case we have the same issue? Thnx

More Detail about the LG E900 WP7 Lock Screen issue
OK. SO here are the symptoms-
- Whenever I enter the lock screen, the touch is screen does not respond. TO be clear the touch screen senses I am touching the screen but the lock screen doesn't move when swipe.
Ater some research you can find the SAME EXACT error on HTC Surrround Samsung Focus. here's the youtube video. exactly as it appears except time to unlock takes about 2:30 (2 minutes 30 seconds) on my LG
http://www.youtube.com/watch?v=t3QABdcTINc
So here is what happens and what I do
1. Again entering the lock screen, and attempting to unlock the touch doesn't reposnd to any swipes.
2. You continue to swipe and occasionaly hit the physical buttons. This keeps the lock screen on. You have to keep swiping for about 2:30. After 2:30, the touch screen just seems to respond.
3. After the touch screen responds. Nothing out of the ordinary. When I tried using IE, it seemed that IE didn't work as well. Pinch to zoom, swipes not as good. Also portions of the screen are not as responsive.
So maybe start looking for a replacement.
I've tried
- restoring previous OS and files. No change.
- Hard and factory reset. No change.
- changing the brightness setting (AUTO, low) no change
The only thing that I haven't done is upgrade/downgrade the firmware. I think that may help but not clear on what to do.

Are you using the correct charger?
I have an HP Touchpad that has a high output microUSB charger for rapid charging of the Touchpad's battery. Although it hasn't (yet?) given my e900h any troubles, I did read at least one report of a guy's Samsung phone reacting poorly with symptoms similar to yours after using the Touchpad's higher output charger.

I am using a third party USB charger. Not a high power one, but an inexpensive one from monoprice. Ok, I will try.

Some people have reported errors and crazy system behavior when using third party chargers...

Still no luck. Using stock charger now. Will wait to see if any improvements. Thanks everyone.

I was one of them. This behaviour would occur with the charger connected.
I get the feeling the problem the OP and I are facing is also related to chargers, but no longer when they are connected. Charging makes no difference for me, the phone is still reacting very strange.

More Info on failiong touch screen
So
Here are more precise deets
- Whenever the backlight is turned off, the touch screen becomes non-responsive
- The touch screen notices touch but not swiping.
- in order to get the touch screen to respond you must continue touch the screen for 00:02:30 (2 minutes, 3 sec).
- the touch screen will usuallly start to respond to swipes but only a single axis (e.g. vertical or horizontal)
- after 2:30 the touch screen responds like everything is ok.
- the goal is to make sure the screen backlight stays on until the for 2:30. In some lock screen cases, you can issue a voice command, camera etc which effectly keeps the phone one (i.e backlight on) for longer without having to continuously touch.
- issues came after tangoi install and livestrong install.
- wonder if tango did something to lock screen
- also tried changing lock screen wallpaper - no changes
- when installing microsoft insider app, I tried using the wallpapers, but the apps crashes. Changing wall paper using default app works
- using default charger no changes
- received the latest update (fixed voicemail and outlook issues) - no change
I haven't been able to retore/flash NODO. That is probably what I need to do.

same problem here, new phone, original recharger and touchscreen of my optimus goes sometimes frenzy...the frequency of strange behavior raises when I fully recharge battery
i found a video on youtube, but yet i cannot send urls, because i'm new user here, u can find it if u search "problema telefono"
