hardware problem? - G2 and Desire Z Q&A, Help & Troubleshooting

hi, had my desire z about a year now, since ive had it, quite rarely ive had a problem of it seeming to have a mind of its own, for example, icons may be selected, or the home screen will slide accross by itself etc. ive always put this down to a trackpad problem.
the other day (after having a miui rom installed for about 2-3 weeks, which was fine untill now), it started acting up strangely, the above problem started happening, but more severe, also the touch screen and softkey buttons would stop working for periods of time (or stop completely untill reset), but screen rotation etc would still be working, which shows that the O/S has not frose and is still working behind the scenes (making me think its a hardware problem).
now, i think ive worked out that this seems to be triggered (mostly) when i open the keyboard. (as also, when the touchscreen stops working etc, sometimes, sliding the keyboard open and close several times, will sometimes seem to unfreeze the touchscreen etc, and will be back to normal, for a while). ive tried doing full wipe and reflashing etc, but i still have the same problems mainly when using the slide out keyboard, which again, makes me think its hardware (possibly keyboard ribbon cable?)
i really dont want to send it off as that means getting it all back to stock etc, and last time i needed the screen replaced, took 6 weeks to get it back!
if anyone could pinpoint the likely source of the problem, id rather replace the part myself..
would anyone have any ideas, as they would be very much appriciated... Thanks...

anyone at all?

I got 2 Zs meanwhile but dont have any problem with the keyboard.
But sometimes when its charging i got the same issues like you - no touch is working and the screens are sliding nearly automatically.
I think this has nothing to do with the keyboard...
Hope this had helped you a bit

thanks for the reply, unfortunately im still no closer to finding source of the problem, its intermittant, happened lots yesterday, not so much today, maybe the digitiser? its like there is another invisible finger touching the screen..

This would happen when i was on stock froyo, like it would cause the home screen to hang, but if i was ion an app it worked fine. I would use it to refresh of sorts when my phone was hung up or i need to reload my apps from sd lol. Sounds weird I know, but even with stock froyo i had problems with my keyboard but with the prerooted GB its as smooth as butter...

still going on, and getting more frequent, i dont think it is to do with the keyboard anymore. im now guessing it is the digitizer, its like someone is pressing an invisible finger on the screen, roughly in the center. it comes and goes, it happens for about 3 days, then goes away for a couple of days etc.
also there is very little info anywhere on the net that can help, including replaceing the digitizer itself
anyone ever replaced one on a disire z/g2?

Less responsive touch screen at random times

It seems the touchscreen of my Desire gets less responsive at random times. Anyone else who has this problem as well?
The touchscreen of the Desire is very sensitive in most cases. But it sometimes (randomly) becomes less responsive. I have to give more pressure for the screen to register the touch. This is especially annoying when typing an e-mail or text message.
But for example: when sliding between the screens at the homescreen (Sense), you have to barely touch the screen to slide. When my 'problem' appears, I can actually feel and slide on the screen but nothing happens. When applying more force it does work, but is not as comfortable...
When I reboot the problem seems to be gone for a while, but at some point it becomes less responsive again.
Obviously I have tried uninstalling apps and widgets and see what happens then. But the problem remains. Hard reset/factory reset appears to be working at first, but again after some time the screen becomes less responsive again. This can be after a few minutes or after a few hours. The only way to 'solve' this is to reboot the phone again.
So! Is there anyone who is experiencing the same problems? Because of the factory reset (and obviously not installing any apps after that reset) it seems to me this is some sort of hardware problem.
Any takes on the issue?
I only get such a problem when my hands are sweaty or sticky and when the screen is smudgy. I'm a cleanliness freak though so I naturally keep my hands and the screen very clean avoiding this problem. Otherwise everything is pretty darn consistent on my side... except for one oddity.
I struggled with this phone for months and then gave up trying to type or even just use the touchscreen while it's laying flat on any surface. Most of the touches just never registered, honestly. Even when applying a lot of pressure. Until last week, quite unexpectedly, the touches started registering perfectly. Just as good as when holding it vertical. I was quite amazed and baffled at how something just changed automatically to improve it significantly. The only other observational change in sync was that some apps that kept changing the phones layout based on the way I'm holding it even when I had disabled this feature (like the Tapatalk XDA app) have started working correctly as set now. Just all of a sudden.
I haven't made any setting or config change. I did root a while back but unrooted very soon after by flashing the stock T-Mobile ROM and things were still as bad as the beginning. That's something like 2 months back.

Ok, weird!
Since I am able to reproduce this with and without installed software (hard reset, no sim, no sd, no nothing) I can only assume it's some sort of hardware problem.
So off to repair department it goes! Thought I'd post it here and perhaps someone would have a solution saying:"Oh! That's this or that". You never know
What I found is sometimes it's unresponsive but it's *puts on black roll neck and jeans* the way that I'm holding it.
I think if you squeeze the phone too much it registers a touch on the side of the screen. Also so times when I'm using it one handed the ball of the bottom of my thumb touches the screen and this is registering, making the rest of the screen unresponsive.
I'd consider this to be the problem first (as annoying as it is). I used to have the 2nd problem on the iPhone, but not the first. It's a bit upsetting but I got over it.

Are you using a screen protector at all?
Since you have the same problem after performing a hard reset, maybe you should consider taking it back to the vendor for a warranty repair or replacement as it could be a faulty digitizer.

[Q] Input problems

Hey all, today I just started having a problem with my touch input. Sometimes, it won't register my touches at all, including the hardware capacitive buttons at the bottom. Sometimes, turning the screen off and on will fix it, sometimes it won't.
Other times, I'll get what people call "ghost touches"; the screen is reacting as if I was touching it in certain spots when I'm not. Honestly, I can sit back and watch as my phone uses itself (it's really creepy actually).
The weird thing is that this just happened out of the blue. This morning my phone worked perfectly fine; I had never seen this issue before. Then all of a sudden this started happening. I am using CM6 nightlies and I have tried everything. I wiped everything, flashed the new nightly, flashed a stock 2.2 ROM (with Sense), changed the NovaFreq values, tried a kernel without the FPS unlock, and the problem persists.
Does anyone know how to fix this issue? If it has been over 30 days since I bought the phone, will Sprint still replace it?

[Q] Mytouch 3g Slide Screen Issues ? (WARNING : EXTREMELY LARGE PHOTOS)

So recently my mytouch has been getting worse and worse. I'm not exactly sure if it's me or if it's the stupid phone because it's been degrading over time for some strange reason. First of all, the camera is **** for some reason, this is my second replacement phone from T-Mobile and it's extremely blurry for some reason(apparently it's a common problem but not common enough apparently for the tmobile representatives I've met with have seen before). Secondly, it's been becoming unresponsive at times although i kill my apps after i'm done with them(I probably only have internet, and facebook running most of the time). Third, ever since I've factory reset it, it's become very glitchy for some reason. One of the problems is that I would close the physical keyboard but after sending a text and all of a sudden the screen goes black and the only thing to fix it is to hit the power button and press it again to get it off of sleep. Another problem is after i send a text i close the keyboard and the screen repeats but the location of buttons is still where they're suppose to be on the screen.

Third Problem(Glitchy screen)

As you can see the buttons are on as the phone is on but the screen is black and unresponsive, i realize i can still go to apps while like that somehow but to fix it i just hit the power button which shouldn't be happening though
Fourth(Repeat Screen)

As said before unless you didn't read this happens after i send a message and close the physical keyboard...
And thank you for any suggestions you guys have, help is appreciated, also for taking the time to read the thread
Jezussss!!!!
Dude.. you dont need pictures, and if you post them.. resize them first.
Make the thread want to be readable, like-able. Ask yourself, would you read this thread?? and with yellow highlights that no one can even see????????
You also need to post if you're phone is stock, what rom you are on, what version..

This is a hardware problem (the repeating screen) that seems to be happening to many people. (it happened to me before which is why i replaced my previous slide). After my 2yr contract is done, im gonna stop getting phones with keyboards because this also happened to my previous htc slider phones

So it's actually because of the sliding part of the phone ?
I'm not surprised, this phone was pretty cheaply made imo, literally a piece of crap :\
I guess I'm getting the new iphone once it comes out and my 2yr contract is done

Oh I see, well I tried to get it replaced but HTC was a bit suspicious when they wanted my credit card before anything ......
I have the same issue with my phone
As I was looking at your photos I realized I have the same issue going on with my phone. Does anyone have suggestions on ways to fix it? Personally, I do not believe it is a hardware issue. I do believe it is more of a software issue. That update that HTC offered is definitely screwed up! Ever sine I updated my phone, all of these problems started. This problem did not occur beforehand! My phone was working fine - before this "software update."
Same Problem
I had the same exact problem with the Repeating Screen (and completely agreed about the camera lol). Yesterday I tried demonstrating to my friend the problem, and permanently blacked out my screen. Now, the phone works in the sense that it receives calls, the home keys light up, and the camera still takes pictures. However, with no screen to select any options or perform any functions, the phone has been rendered completely useless. I, too, would like to figure out what the problem is and if there is any possible fix.
Sorry I couldn't be of much help. Just know you're not the only one lol
My girlfriend had the repeating screen issue back in May/June of this year. It was more than likely a software issue, because it became incrementally worse as the phone opened and closed until it came to a point where absolutely nothing could be done when the phone was moved horizontally.
I had T-mobile replace the phone at the time. Unfortuntely an idiot I work with who was supposed to mail it back didn't, I got stuck with an extra $360 on the bill.
Worked out paying for the phone with them yesterday morning, this morning my girlfriend messages me to let me know the screen is acting up again.
Potential Fix?

I would recommend replacing your flex ribbon. It worked for me, and from other threads I've read, I believe it's the cause of these issues. It's a pretty easy fix ( coming from me, who's far better at breaking electronics than fixing them, lol ).
Here's the flex ribbon that I bought off of Ebay ( it's the cheapest I found and it comes with the tools too ):
http://www.ebay.com/itm/170647168235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
And here's a good video on disassembling your Espresso:
http://www.youtube.com/watch?v=-jgFHuVWlig
P.S.: I'd recommend being more delicate than he was with the volume ribbon though, as mine seemed very frail. Also, this video is for replacing the digitizer, so you only need to follow it to get to the flex ribbon.
A month ago, I had issues very similar to the ones you posted. Sliding my keyboard out ( in any way but gently ) would occasionally split the screen or freeze the phone. Even without using my keyboard, the phone would occasionally freeze while "settling" after the boot animation, and sometimes even during the boot animation. Slowly, those "occasionally"s become more and more frequent, until my screen just went black one day. The phone still seemed to work ( lit up when turned on, made sounds, etc. ), just the screen seemed dead. Figured that I was having a combination of software issues ( the random freezes ), and hardware issues ( split & black screen ), but replacing my flex ribbon suprisingly fixed everything.
This is what worked on my MyTouch 3G Slide
i just keep sliding the phone. and turn off the screen then turn it back on. but not turning off the phone.

probably not, look on ebay for some digitizers, cheapest way to get them...

Display becoming possessed and unresponsive

Wonder if any of you have had similar issues or know a fix.
Symptoms:
After using the phone for a long time, typically over an hour or do, the onscreen keyboard starts to behave erratically by generating 2 letters if I type one. Then, swyping doesn't give the desired result. If I zoom in and out in internet, it just starts scrolling to one side. Then the whole screen starts fluctuating. In fact the phone seems to have a mind of its own
Video of the issue: :
http://db.tt/W3XkD0z
Troubleshooting steps tried:
I swapped my sim cards and sdcards to rule out their issues. Unrooted with ruu. Problem persisted.
Htc replaced the touch panel, put in an amoled instead of the slcd I had. They also replaced the main board. The problem didn't go away.
Wonder what could be the cause. If nothing works, I'll force them to replace the handset as a whole, but really like the amoled they've provided..
I had some of the same problems with my Desire under US Cellular. I noticed it the first day I purchased my phone.
The keyboard would just become unresponsive and it was like the keyboard was behind about 10 characters as I was typing (and I was a slow typer with a new phone and first full touch screen). It would also add random letters that I know in fact were not pressed.
Scrolling didn't give me as much trouble as you are going through, but still seemed very buggy.
The entire phone would seem to slow down as hours past and it remained on. I tried a hard reset, and even like you, removed the SD Card and nothing.
Took it back to US Cellular, showed the guy what was going on and showed him after a reboot how it would clear up... and they exchanged, no questions asked. I think it was just a corrupted phone. The new phone runs very smoothly.
By the way, the DB link you provided gives a 404 error. I would like to see it to compare with how bad it was for me.

Top half inch screen not working

I have a HTC One m8 and the top half inch of the screen does not respond but occasionally it does sometimes for a little while. The top half inch generally tends to work when the battery is charged to 100% but sometimes that doesn't happen either. if it helps I use a tempered glass as a screen protector and the screen does not have any physical damage and it doesn't help when u boot into safe mode. I have also tried a hard reset.
Coincidentally i am working on a phone with the same problem (not mine). After a lot google research the owner decided to use another Launcher (Smart Launcher). This did not fix it entirely, if you are in Apps you can use the statusbar, but its not working on homescreen. I dont know why it behaves like that, but surprisingly many people get problems like that. I tend to believe that there is some software problem involved, because changing Launcher or using custom rom has been reported helpfull/fixing the problem (not allways tho..).
Now he had some other troubles with this phone and in the process i did a reset, that did not fix things as you said. I will install a custom rom next and will report back next week.
So i was wrong with saying a new lauchner solved the problem. Statusbar(sb) was accessible in home screen but not in app, said it wrong in the other comment. Now i had some time to test this and i can say that at least the phone i was working on is broken.
The top part does not recognize any touch input. The reason the sb showed some reactions is, that the launcher had a bigger trigger area (i guess), so you could pull it down. But still the top part was not responding. I tested it with stock, S-Rom and one Nougat Rom (dont remember), none of that showed an input in the top part.
Solution for now is different launcher or app that pulls down the bar. There are still some problems in daily usage, that this will not fix, so i guess its time for a new phone.
I am facing same problem. Is it any update which was pushed by HTC which makes the top 1 inch unresponsive ocassionally.. Indirectly, a marketing gimmick to push us by a new phone. So if it is really like that, who would buy a HTC phone again anticipating same problem again. Might go for Samsung (my own preference). huh !!!
