Hi, everyone. i found this problem in other devices' forums here, but wrote this to see what caused it on our x8. recently, i noticed some crazy finger tracking; no tap and hold recognition like in scrolling; it read like a zillion single taps causing random open and selection,..... etc.
finally and after flashing several roms and using SEUS, the problem still was there. luckily, i found it was due to USB cable connected to my PC. Strange really as it never happened sice i first got my phone 2 months ago.
nothing new except the average; which is flashing a rom or two daily and applying the modules overclocking etc
so what could be the new thing that happened that caused this problem ?? i can say that those past days i was continuously connecting my phone to PC .
any ideas ??
Wrong Section
I have the same issue, and the conclusion I came up with is that my pc is not properly grounded and there is some static that is making the keys press twice and make the screen really sensitive. My 2 cents.

that's pretty reasonable cause. thanks for notifying me; now i know why i didn't have this problem with my laptop.
i had the same problem if i connect a unorigional adapter with less power
maybe that's because u use wrong usb cable.

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.
I need a little bit of help.
I've just started having a very annoying problem with my HD2. I does not shut down.
Each time I try to shut it down it just restarts.
If I have the battery taken out and I put it back in, the phone turns on automatically.
I tried various ROMs, reinstalled the HSPL, used Task29 various times and the problem it's still there.
And the most annoying is that when the battery reached the critical status (low %), the phones just enters a continuous loop of restarts until the battery is completely dry. Because I cannot turn it off the only solution is to take the battery out until I have the opportunity to charge the device
I don't know if it is a software or hardware problem. I think it should be software but still I do not have any clue on it.
Did anybody had this problem up to now? Any help would be more than welcome.
interesting problem. Most times if a problem persists across hard resets/ rom flashes with task 29, etc, then it is usually a hardware problem.
Have you tried calling your carrier or htc for tech support, maybe a new phone?
Solution?
Hi,
I also had this same problem. I solved it, strangely, by plugging the phone in to charge then unpugging and reseting. Hope this works for you too!

Unfortunately I cannot benefit from the warranty service or free replacement.
The repair costs would not be an issue. The only thing that bothers me is that I don't know if is a hardware or software related.
If I consider the symptoms it should be soft related. But if I consider the thing that nothing of the above mentioned worked, then I have to tag it as hardware issue.
The only thing that could trigger such a behaviour is the fact that this weekend I had it in some high temperature environment ... trying to hold the phone which was charging, in a car without AC, outside temperature 37 Celsius in the shadow, I almost burned my hand ... so maybe some strange protection was triggered.
Another strange behaviour it had, is that i could not charge it on various trials. With the charger connected, in car or at home, it would not charge and the signal led which on normal charge is amber, in these cases was blinking between amber and green.
if the phone gets too hot, it won't charge. That is a safety feature.
Make sure you check your battery contacts as well, where the battery sits in the phone. If the middle one is bent so it doesn't make contact with the phone, it can give you the flashing led.
I thought I read on here that the hd2's were warrantied by htc for 2 years, based off serial number. Wouldn't hurt to call and see.
But it sounds like something fried in the heat.
Thanks for the feedback. I'll try to see if I can have a service check on it.

This issue has been discussed many times. A lot of people (including myself) has this problem. Try to put it into standby mode and after half a second, the screen comes back again. I have searched the forum many times, seems that no one has come up with a complete solution. Looks like it is not a hardware issue as most people found that if you connect it with your PC in activesync mode, it will resume normal.
My experience :
1. The problem just come up all of a sudden. Haven't install any software or apply any tweaks a couple of days before it happened.
2. Try to look into the active service via memmaid, nothing special.
3. Restore from previous backups when the machine hasn't got any problem. Didn't help.
4. Soft reset a couple of times. No use.
5. Hard reset finally. Problem still there.
6. Start to doubt that it is a hardware problem.
7. Use the plugin method. Normally after activesync, it resumes normal.
8. Also try to plugin micro USB without real connection. It sometimes works.
(I started to think that it might not be a hardware problem. It is obvious that when plugging in, something "stops".)
9. However, either way, it will happen again all of a sudden.
10. Start to take a few irrational moves : install BSB tweaks (haven't install since it sometimes crashes with Cookie's home). Switch to power saving mode with BSB.
11. Stop windows live autosync.
12. Install XDA shutdown. Whenever connected to PC via activesync, will manually put HD2 to sleep mode using XDA shutdown. Then unplug.
It has been four days now, everything resumes normal. The problem just gone all of a sudden. I really don't know what is the reason behind and which steps being taken is a solution. Anyway, that's my experience. Will update again for any changes again.

but if the problem persists across several roms and radios, how can it be software related? The fact that plugging it into the computer or charger sometimes fixes it, leads me to believe that it is the female usb connector that is the problem.

You might be right. I really dun know if it is a hardware or software problem. But, it's kind of interesting that after u plugin it will work for quite some times. And, it will come back after the next soft reset.
OMG!! ... this means that I've just got the HD2 Ebola disease. )
Now being serious, after flashing 3 ROMs, hundred of soft resets, battery in out ... and one long night ...I just give up.
I will just try not to have the phone discharged. I hope there will be a solution sometimes soon.
Possible solution
I had the same problem.
I removed the cover, cleaned the two contacts on the back of the cover and for some unknown reason it returned to normal (although I was holding a pencil in a threatening manner to the red reset button).
What are these nodules for? I think more to do with reception, but it worked perfectly.
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.
Hi,
This might be a newbie issue but my HD2 was working well up until few days ago when I noticed that everytime I make a call instead of ringing normally it does it in speaker (hands free) mode what caught my attention since I didn't change any settings.
I'm inclined to think that it might be due to some corruption in the software since I didn't find any optios to revert this so I was thinking on doing a hard reset but...
The other issue I have is that I tried to connect it to two different computers (that it used to connect without problems) and it does not do it.
It does charge on the USB but neither PC's recognize that the phone is connected.
I tried 2 different cables on the 2 PC's without luck.
So again I'm now more convinced that it is a software problem.
Any idea how should I proceed so I don't loose any data????
Thanks,
Look up "stuck in car kit mode" see if it's the same symptoms.
I look into it thanks...
I looked it up,but is not exactly the same.
It's stuck on loud speaker yes but not in landscape mode, if I rotate the phone the screen works ok.
It also goes to sleep so they are not exactly the same
It just does not get recognized by the pc when I plug it on the USB.
I just get the charging light and the little plug simbol on top as you get when you plug to external power but the computers don't make the sound (or any sign of recognition) that normally comes when you plug any USB device to it.
Unless this is just the start of it...
Well, after reading all 12 (or so) pages on that thread and cleaning the heck of the micro usb, wigling the cable in every direction this morning I managed to connect the phone to the PC and get rid of the loud speaker, so even if the symptoms are not exactly the same looks like it heading in that direction.
Bummer...
I guess it's time to start looking for a new phone.
My tablet suddenly started to suffer from "ghost touches". I already factory reset it and removed it's (great) screen protector, but to no avail.
Any thoughts besides service it?
Thank you!

Updated 1: problem solved rebooting to safe mode.
Update 2: see my post (#8) dated 10/10/18.
Does the problem occur all the time or only with the charger plugged in?
The reason I ask is that my Android YB has a similar problem with the Halo keyboard. Pressing and holding the shift or backspace key generates random characters. It happens only when plugged in and (interestingly) only in one room of the house. I've yet to find a reason, so I just unplug the power and run on battery while typing.
Another thought: my old Nexus 7 sometimes does the same thing (random touches) or becomes non-responsive. Turning it off and then gently squeezing around the edges and the middle of the screen fixes the problem for several months. I'm guessing that some internal connector is going bad (loose or corroded). It's one of those "can't hurt to try" things.

Never tried plugged.
But I found the solution: just like Windows (!?) I rebooted to safe mode and... ...it's fine now. Seems that it was some weird driver error that a factory reset alone could not fix.
Thank you very much for your help!!
I just got a "refurbished" one from Amazon. What a nightmare! The random ghost touches are so bad I can't use this damn tablet! Now I have to send it back, get a refund and buy another. Ughhhh.
You rebooted into safe mode and then what?

Unplugged, fine

Tried another cable and charger?
I've found a workaround that made de Yoga usable again. In short:
1. Find where are the ghost touches using (developer options -> show taps). If you're lucky as I am they will be confined in just a few pixels is some border.
2. Root the device following this link:
https://forum.xda-developers.com/yoga-book/how-to/root-yb1-x90l-how-to-t3534268
3. Use some "screen resizer" from Google Play in order to disable the faulty row or column. In my case I started disabling the first 20 pixels. Now I'm with 10 and the Yoga is still usable.
