Touch screen buggy sometimes. - G2 and Desire Z General

For some reason recently my touch screen has been kinda buggy. It registers my touch just fine but doesn't register it when I take my finger off the screen. It only does it sometimes other times it works just fine. I've removed my case and cleaned it even tried reflashing my rom or trying other roms but it still does it. Any ideas?

I have noticed this with my phone as well, it started after i dropped it, on to pave ment, screen down. I know all of you just scringe!
Luckily the screen didn't break, but every now and then, it will think I'm doing a long press. I'm going to be doing a warranty replacement with asurion on soon as I think something happened with the hardware.

Well I havnt dropped mine like that...
Looks like it is hardware related though. What's odd is it only does it sometimes.
If I do the warantee relplacement I assume I have to unroot it and put it back on stock firmware would I be correct on that? If so is there a decent guide? I used the gfree method.

Vibrant Touchscreen Unresponsive

The touchscreen on my Samsung Vibrant stopped working this morning..It worked fine last night and this morning nothing..Tried a factory reset through Odin and still unresponsive..
Can anyone help me?
If you've reflashed and it didn't fix the problem, and nothing damaged the phone over night, then its probably more than a simple loose connection issue.
May have to get a warranty replacement.

Nothing damaged the phone..I was rooted with the stock Rom running OneClickLagFix from the market..
This morning the touchscreen stoppen working, was able to reflash back to stock using Odin..And touchscreen still not working..
Tmobile is sending me a new one, but would sure like to fix it before than as I hate using the loaner phones they have.
You sure nothing happened to the phone? That seems very strange. Are you using a screen protector? Download any weird apps? Kinda scary that the screen would just fail. You didn't do much to the phone as fast as mods go while some people do crazy stuff.

Is th phone plugged in? The screen gets very iffy while plugged in.
Weird. My screen was not accepting touch input about 10 minutes ago. However, a reset fixed mine.
I'm sure nothing crazy happened to the phone, It's only 3 days old..I had to have my other one replaced under warranty and I just got this on Thursday night.
things like that happens, looks like you need a replacemet.

Ever thought perhaps that had something to do with the issue (i.e. trying to OC it messed the phone up and eventually the digitizer failed)?
Only asking because some people think "oh it froze, but it booted back up fine. All is well."
It's like being surprised you have Lung Cancer because you quit smoking last year, but smoked for 30 years before quitting...
Also, using some after-market car chargers can kill you touchscreen. I've had that happen before.

MT4G Turned Itself Off & Power Button Won't Work

Ok.. so this is the second time this has happened..
My phone was fully charged and for no apparent reason turned itself off. Then when I attempted to turn it back on, the power button would not do ANYTHING at all.. even after multiple presses (like 20).
I plugged the charger back into my phone, and the light wouldn't even come on indicating that it was connected to the charger.
Finally pulled the battery, put it back in, and viola - it powered up.
Then I was talking to my buddy and the same thing has happened to his MT4G. Except he never pulled that battery - but he said it took 15 minutes before the power button worked.
I think this is a BIG problem, because when I started searching the net for similar situations, I found one.. with the G2. Now that's TWO T-Mobile phones with the same problem.. Both made by HTC.. both with several Quality Control issues
Anyone else have this problem? I'm starting to think about going with a different phone now, which is crazy because I was absolutely in love with this phone... but I am not about to have a phone that decides to shut itself off and won't power up. Especially since my friend has the same problem which tells me this isn't something specific to my phone only which means potentially any device I get can have this issue.
I was deeply saddened to read the G2 has the same problem. What's going on HTC????!
Are you rooted? Overclocked? It really sounds like phone couldn't handle amount of OC (which happened to me several times). However, if it's a stock phone - hurry up and bring it back to T-mo and ask for replacement. This is not a common issue for these phones, first time I hear about it. Of course, there always will be cases of QC but, once again, this is not a common behavior.
I can say this has never happened to me so it sounds like an issue with your setup. Do you have anything modded ie overclocking is the one I'm thinking. Maybe pushing phone to hard.
Edit: sorry just realized I was in the general section.

No, I am not rooted. Stock running Launcher Pro Plus and Live Wallpaper.
After checking around, it appears this has been an issue for many G1, G2 and even a few Nexus Ones.
It appears the general consensus is that either the contact pins for the battery are not making firm contact when the battery shifts (supposedly on some phones the battery prongs not protruding enough, I have not checked mine yet but I intend to shortly)
I really don't want to return my phone.. my screen is the good one and my FFC is centered..
This happened to me just an hour ago. Only had the phone since friday and had this happen for the first time. Wouldn't respond at all. Everthing stock on phone.

Well I would return it because you chances of getting another good one are pretty good.

Yeah, but what are the chances of getting one with the good screen, a centered FFC and no gaps in the metal bezel/side of the phone?
I'll wait it out and see what happens. There's always the warranty.
Same thing happened to mine. I took it back. It wouldn't charge and the power button didn't work.
I pulled the battery and it still wouldn't cut on or charge.
Phone was stock.
It magically came on by itself 5 minutes later without me touching it.

keyboard popping up randomly and other strange things

I am running the CM7 with the newest OTB kernal, and I am still getting the keyboard randomly popping up, the back key randomly will work 2 or 3 times in a row. I had the same problem on EF 3.6, com rom and even on the SC roms. Has anyone else had these random key strokes? I heard it was a froyo related issue? Is it hardware related? I had a screen protector that covered the soft keys and removed it, but it is still happening. Any thoughts on how to get rid of it?
FWIW I have odined back to stock, with the atlas pit and even used the ext4 reformatter before I switched to EF3.6.
Any help, advice or thoughts would be great.
I encounter the same issue but it always seems to happen when on the edge of losing cell signal. When going back n forth quickly from service to no service the capacitive buttons (I believe that's what they are called) seem to push themselves. And I have noticed this issue since DJ05 on any rom I have flashed since then and any kernal. I have run just about every rom posted except for miui and cm7. I can not confirm if cm7 has this issue because it is on my other fascinate and not on the cell network. I have terrible signal in the building at work and I have always seen this happen there, at least once a day.
You know am pretty sure I replied to this question before. I guess no one else has really has this issue and the thread died.
Also didn't matter which radio verison I used. I have come to terms that my fassy is just possessed lol
Sent from my SCH-I500 using XDA App
apparently you and I are the only ones that it happens to. I was hoping someone could give me some insight on how to at least find some relevance to a rogue program, bad kernal/rom combo or something. It's very strange and it does it to me more than once a day, and I have good signal most of the time.
Happens to me all the time when I'm at home where I have terrible signal.
I just started having this happen on CM7. The keyboard or the menu would randomly pop up. For me it happened more than just when I had bad signal, but it did seem to happen more often when I had poor signal.
I have this problem too, it would back out of apps I am in too. Quite annoying.
I've been having this problem as well on CommRom 2.1. Seems to be related to poor signal for me. It's pretty annoying to deal with.
Happens on a stock device also

Um. No. Not in my experience. Its something that has been well known that is associated with weak/intermittent signal. Didn't start for me until Comm Rom and became more pronounced with CM7…
This happens to me too. Oddly though it only seems to happen during the night when it's plugged in and it doesn't happen all the time. Sometimes I will wake up in the mornings and my screen is on and the keyboard is up.
Do a search for phantom softkey presses. It's pretty common and is a hardware issue.
I as well have this happen. Mostly it happens in low signal area. Recent, my keys just stop working, until I got better signal, or sometimes I am forced to restart the phone.
I just went back to stock ED05 mainly because of this ultra annoying issue and I am completely devastated to find out that it's still #$*%ing happening.
I am so pissed too because I called VZ a week ago and they offered me the Charge replacement, but I couldn't make it to the corporate store until yesterday where I was informed they stopped the replacement policy that day and that I was SOL. Argh. So angry.

I commented on this a while ago in the CM7 thread. I have it on stock ed04.
What I wanted to know was if you guys have a screen protector on yours or not.
I wondered if my Zagg Invisible Shield was what was "pressing" the capacitive buttons.

Verizon makes a metric **** ton selling screen protectors to those spending $200+ on a smartphone that doesn't need it.

Well, just to back this guy up. I had it happen back before and during the time I rooted my phone, and it still happen after I returned to stock (via Factory reset and OTA updates).
EDIT: To the guy who asked about the screen protector, I did have a ZAGG on there, then took off only the section covering the softkeys. Still did it even after I made sure to fully clean it to eliminate any residue. Took the protector fully off, same full cleaning, and it seemed to have gotten worse (if thats possible lol).
I'm about to call tech support, but wonder if it's worth it now that the good trade-in is over.

yeah im sure it happens but its fairly rare on a stock phone i would say....
I have it happen semi-regularly. I'm currently on MIUI 1.7.22 / Glich 11.1 / ED05 radio, and never used a screen protector. I also had it happen back before when I was on Super Clean 2.9.2 (don't recall the radio), as well as most any other ROM I've been on.
It's not too uncommon that I would hit the power button to turn off the screen when back on SC2.9.2 and instead it would take a screen shot, because it assumed the back button was being held down!
Gotta love the Fascinate...

Yup, I got the same issues! Although minor, these things just shouldn't be happening? There's gotta be a fix for this?!?!?!

touch screen problems?

I have a small line on my screen that is unresponsive. It goes straight across the top of the screen exactly where the install button is in the play store (about 1" from top of screen at roughly 1/4" thick). Its in a pretty awkward spot and causes a lot of problems. For some reason it has also disabled the tap to wake feature of my phone.
I installed the "Touch Test" app which shows that my entire touch screen is working. However it shows the phone recognizing 2 pointers (touches) being active whenever I touch that area of my screen. I've been having this problem for 2 or 3 months now and all of a sudden today on my lunch break it went away. I was able to tap to wake the screen (worked perfectly the 20 or so times I attempted it), I was also able to hit the install button in the play store and life was great... Or so I thought. A few hours later on my next break my phone went back to annoying piece of junk that I completely dislike using.
Now I dont know exactly when this started happening. I did notice it sometime soon after the 4.4 update, and flashing a custom rom/kernel has made no improvement. Anyone got any ideas? I loved this phone before this started, and my phone is so frustrating now that I completely disrespect the thing and have scratched the crap out of the screen. I'm really hoping this can be fixed so I can go on with enjoying whatever life I have left with the g2, if not I'll probably just abuse it until it breaks then switch over to a water proof z2 or something along those lines... Phone was very well taken care of before the problem started, wasnt dropped or exposed to water (other then using outside in the rain for a few min at a time)

I have this problem too, any fixes?
Well I am in shock as to how we all have the same exact problem.
I first thought it was hardware failure on the screen itself and was pretty bummed. But now I see people have the exact same unresponsive touch screen in the exact same spot as mine? What ROM/Kernel are are you guys running? I am running what is in my sig and had not noticed it before until a couple of days ago. Coupled with the unresponsiveness, my Knock on does not work and the phone becomes mildly warm faster than usual. I think it might be a kernel software issue.
Ugh... I was hoping this wouldn't turn in to this big of a problem. I've got the same thing here, VS980 after flashing a Cloudy ROM.
I took over a thread here recently http://forum.xda-developers.com/showthread.php?p=52858791 , but I'll post here again anyways. I wonder if it's the same spot with you guys too. It's right where the install button is on the Play Store, right? For a few hours after it started it went back to normal, then messed up again permanently.
TOT'ing back to 12B didn't help, so I got a replacement device from Verizon. I've yet to send back my old one because I'm worried about the unrooted flag in the bootloader and settings.
I don't have enough posts yet to be able to do this, but can someone alert a dev about this? Particularly in the thread of whatever ROM it was that you last used? A lot of people in the last thread said it came from Cloudy, and I figured it might make sense as Knock Code was supposed to be a feature on there even though the VS980 source wasn't out. Then again I probably have no idea what I'm talking about, but I'd love to hear from someone who does.
I dont think my blacked out area is quite as thick as yours but yes its in the exact same place. To confuse things even more my phone just started working properly again (for how long is another story). Its very odd that It hasnt worked once in 2 months or so and now twice in 2 days its started working.
As a side note I'm pretty sure I started having this problem immediately or very shortly after the OTA kitkat update. I'm now running cloudypro II 2.0 with 3.4.0 kernel, which as i said before didnt fix the problem in the 1 month ive been using this rom.
I originally thought it may have been a software issue, but for it to randomly start/stop working all of a sudden after so long of no function (with no software being added or changed) I'm thinking its more likely a hardware problem? When I fly home on Monday I'm going to try opening up the phone and cleaning the contacts to the from the touchscreen to the mainboard.
If it is software related it may have something to do with air plane mode. I get almost no signal where I'm working at the moment and the constant searching for signal kills my battery pretty fast so I've started using air plane mode the past few days. Thats the only thing out of the ordinary that i've done software wise.
Having the same issue!!

Yes, we've sent it to LG for repairs and they were able to fix it easily.
Sfkn, was your phone rooted when you sent it to them? I'm having the same issue, and it either started happening today, or I just noticed it today, but it's bugging the crap out of me. I'm running stock kk, rooted with twrp and on the cloudyfa kernel.

Had the same today but at the middle of the screen, I pressed on the corners and around the screen pretty hard and it is back to normal(for now).
Hope it wont come back.
You can unroot the device by flashing original rom with LG flash tool.

Touch screen Z3C

Just diagnosed a strange issue. After installing the touch screen protector I've noticed strange behavior of my phone. It seemed very unresponsive and I decided to ingage the glove mod. But the issue was still there . Tried to take off the screen protector, still the same s**. Then started the diagnosis and here it is??? How is that possible that screen protector do something like that?

My phone intermittently has the same issue, but horizontally in the middle of the screen.
Sometimes it works great and sometimes the touch just kind of lives its own life in that non-responsive area and makes touches all by itself.
I've made a video showing some of it when dragging lines like yours in an app called YAAMT. I could link to it later if there's any demand.
Right now my phone is in the repair shop for said issue. Not sure what they'll say, though, since it's an intermittent thing and they need to see it before they can confirm it...even though I've got the video. And sometimes the phone works great for days before the problem comes again.
To be clear, the screen protector did not cause this. Mine was like this out of the box.
I'll try to change my for new one. Now I tried to give you thx and had to touch it 3 times to make it work.

Just moments earlier i droped my phone accidentally by a foot height or so and guess what my phone screen is now totally ok and functional and responsive. I have attached a screen shot of it now u can see...... So may be its just due to some lose connection internally which gets fixed by a drop or so (fingers crossed).... So its up to u people what u want to do( may be try a small drop) but i cant gurantee anything for u guys its up to u people i say again really i worked for me and i am happy for my phone now.......... Hope its also helps u people......... Thanks and share your experience if anything gets better for anyone...............

Not so for me. I had it on the old build as well.
The repair shop exchanged the display and digitizer as well as the back glass on warranty. They also gave me complimentary screen protectors for both the front and the back since I had to wait two weeks for the repairs. It came back factory reset with the latest software update.
I've installed the protectors, and my phone is a totally different beast now. Incredibly responsive with all touches now. No more missed swipes, no more trouble typing and no more of the screen living it's own life.
In other words, in my book, this is clearly a hardware issue.
