[HD2 General] Viscacha:
Now, I'm pretty sure it's a HW problem.

I had these problems and sent my HD2 to repair twice. The first time, they just reset the system and told me they also installed a new touch panel driver, but the problems were still there, nothing changed. So I sent HD2 for repairment the second time. This time, they changed the main board. Now my HD2 works fine without any touch panel issues.

My guess is that these problems might come from touch panel sensor IC which is stuck on main board. You guys who still suffer the problems may give it a shoot and let me know my guess is true or not.
[HD2 General] leobox1:
it may be the sensor is too sensitive.. as installing reduce sensitive cab does help to a certain extend...
[HD2 General] gabriel.twl:
My LEO is only barely even a week old, and a core function (SMS) is like such a chore to do, so i should request for a new touch panel driver? Where did you get your set from? Because i'm over at Singapore, and i'm afraid they might simply hard reset my phone which i have tried to no avail. Experienced trouble trying to replace my handset when i purchased the HTC dream the other time(G1)

Installed at least 3 different cabs and it doesn't help, not even bsb tweaks or hd2 tweaks. Really frustrating. Plus i have another problem which is the display and layout of my messages, it is not in order. it's so troublesome.
[HD2 General] Batas:
So, bottom line: Is it worth trying another HD2...? Or every single one of them will present screen bugs...? expansys has some nice prices...
[HD2 General] leobox1:
yours may be a HW prob.. because for me, the cabs helps.. hmmmmm i do notice that if you depress your finger fully , you get titanic shivers .. a precise tap will be perfect.. u try that?
[HD2 General] jongie123:
Replace it.
[HD2 General] gabriel.twl:
yeah, have you got a replacement for yours? and do you have the timestamp issue in the messaging?
[HD2 General] Batas:
Funny thing is, the store where I bought mine told me that the screen is very sensible and they preferred to refund me rather than keep sending it to warranty.

Now I'm starting to believe that the main problem relies in HTC big capacitive screens. Nexus One also presents similar problems. Watch this:

http://www.youtube.com/watch?v=X3X3w4FKSiM

Now, who makes Sonny Ericsson capacitive screens?
[HD2 General] DuoM:
Yep. I think this problem is down to the HTC sceen and sensor.

Some more info about the Nexus One's touch screen surfaced today and I put it in a thread here:

O2 and exchanges

We've been having trouble with the touchscreen on this phone on two handsets from O2 UK.

We called in to exchange it for a 3rd new one - but the customer service guy said they were now aware of an issue with HD2 screens and HTC is working on a software fix for it.

He therefore advised either waiting for the update or getting a refund. He wouldn't exchange it for a new phone. We pointed out that if we wait for the software update and it doesn't work/get released then we'll lose our right to exchange for a new phone (after 28 days O2send phones to another company - not HTC - for repair or replacement with a refurbished phone).

Of course we all know this isn't a software issue.

I guess for the time being we should avoid getting the phone on O2.
[HD2 General] Eoinoc:
I had this issue, sent the phone for repair and it came back with a new screen which was even worse. Sent it back again and got a third screen which now seems to work fine.

No doubt it was a hardware fault.
[HD2 General] hkan008:
I am not sure if anyone experienced my "6th" problem..

[SOLVED] "Ghost Typer" Problem

A "ghost typer" problem (random touches anywhere on the LCD) has also brought my HD2 to call numbers from my history list in the middle of the night and triggered all kind of applications. I now use the stock 1.66.405.2 WWE but had the exact same problem with previous HTC ROM versions.

In my case I think I now know the reason and it most probably lied in using a low quality (I assume) power unit designed for Nokia devices to charge my phone during the night. There might be other external factors such as weather (humidity --> static) as this power unit ran fine for several weeks before.

Unplugged or using a more expensive HTC branded power supply the ghost typer problem vanished immediately :)

Hope this helps someone!
[HD2 General] luisasia:
Well, I got all your bug and I send to HTC, they changed my touch pannel and the LCD, now the problem is gone even with a screen protector that previously I was suspecting was giving me the problem.

So send the device back for a replacement of the touch pannel.
[HD2 General] waza123:
maybe there is a soft fix ? because i can't send it back to HTC company.

Would be nice if there is a software fix for this bug.
[HD2 General] pablo11:
This cab works best for me. It came from another thread devoted to these problems. Cant remember who made it but thanks to them for the fix:)
[HD2 General] dave wroe:
I had the lines problem, very poor keypad input (getting random letters that were never typed), Phantom screen presses (Apps would launch with nobody touching the screen) It even made calls by itself, which is a two-tap process at least from the home screen.

I took it back to the shop and got it replaced, and touch-wood, the replacement seems a million times better. I can actually use it now without wanting to throw it at the wall.
[HD2 General] waza123:
do not fix the problem :(
[HD2 General] witch1:
I had the random keypress thing. I flashed a new ROM and disabled haptic feedback, no more problem. I couldn't get any of the problems he showed to replicate on my device-no matter how hard I tried.
[HD2 General] adrianfly:
someone has try to do a hard-reset?:confused:
[HD2 General] Batas:
Several times!
[HD2 General] azgo:
I had this totally same issue wiht my old Axim X51v. Its touchscreen was replaced after it broke on concrete. After the replace of the touch came these annoying things.

But I've noticed that the touchscreen is slightly moving upon it's place as the glueing was not so perfect at on of the corners. I was able to glue the moving part almost perfectly and these anomalies has just gone 98%.

So in my case it was definitely hw problem and I'm pretty sure that this is the same with your HD2s, too.

To add: on the 3rd day with my HD2 I've just left it in my backpacket and sit with it (not on it!) some minutes and the result was the oily circles in the middle of the screen (Newton circles). It was replaced in the guaratee but I'm learned in first hand that this robust machine needs very good care to survive...

Sure I carry it in my backpacket :)) I just try not to sit down with it.
[HD2 General] ami20002:
is there any sign or test to choose a healthy device? i prefer to choose a device myself not ordering online, any advise to pick a cellphone without this problem?
[HD2 General] PeterGuru:
You are unusual ...

Remember, capacitive touch screens work by electrical signals from your body, in particular, your fingers. Some people have stronger or weaker electrical charges. Perhaps YOU have a very strong charge coming from your fingers, which is causing many of your problems.

It's just plain science.
[HD2 General] Batas:
LOL No, it isn't that. Equipment fault. I know because I had a faulty one. Now I have another one which works.
[HD2 General] dontcryjustfly:
absolute nonsense... i've got a second new HD2 from April 2010. And it has definitly a other screen. on my device screen is jittering often in all well known situations...espacially scrolling. On the new one it's never jittering!!!!

Here is the Evidence for the different screens...look at the dots on both screens!!!
[HD2 General] CplusT:
Well that's interesting.

Where did you get the phone with the "new screen" ?

Has anybody else this kind of screen?
[HD2 General] dontcryjustfly:
The new one is from O2 Germany
[HD2 General] ThoroSOE:
Had my screen replaced by HTC as well. Before I had all problems named by the thread starter. Now everything works fine. Its like an entirely different device, far more accurate, snappier and gernerally feeling much better. Go and get your screen or device replaced. Period.
[HD2 General] adrianfly:
Have you sent the phone to HTC technical support?:confused:
[HD2 General] adrianfly:
finally, is the problem the screen or motherboard?:confused:
[HD2 General] ThoroSOE:
I've contacted HTC support and they gave me the adress of their local service partner for Germany. But I don't know if they replaced anything besides the screen.
[HD2 General] adrianfly:
I sent the phone is the technical support for screen problems, in 20 days returns... so I think:rolleyes:
[HD2 General] ASCIIker:
i'm currently shopping for a brand new hd2 and i'd like to avoid all these touch screen problems described in this thread. even though i am not an hd2 user, the theory about an inherent screen problem makes sense to me and your photo comparing the two screens seems like fairly compelling evidence.

can you please describe in this thread any markings/identifiers that can be used to determine "old" units from "new" units apart from manufacturing date? this information would be useful for future buyers, such as myself, to ensure that a "fixed" unit is being purchased without having to open the box (most retailers here will only open the box once the sale is final). so any information that can be gleaned from an unopened box would be most useful!

anyone experiencing "misstaps" ?

when typing on virtual keyboard or just taping on icons in the menus device sometimes just doesn't react..
[HD2 General] davidcopus:
SW v. HW

I've just quickly read through this post.

My HD2 (T-Mobile UK, Nov09, sparkly well-spaced dots on screen with closer-spaced in background, now WWE1.66 ROM) behaves on the whole pretty well, so I probably won't be sending it for replacement. Occasionally I get all the bugs listed except for the edge-painting one - but then, my screen fits well.

The point of my posting here:

The hardware thesis seems credible to me, but:

*************************************

I'm certain that typing is much more reliable (less prone to characters being registered as pressed that are some way from your finger) when XT9 is switched off.

That's to say, click the XT9/ABC button so that XT9 is green:

my keyboard is sometimes erratic

click the XT9/ABC so that ABC is green:

my keyboard is more stable

*************************************

That's my experience over 7 months anyhow. I haven't seen anyone else mention it, so I thought I'd put it in the pot.

By the way, Swype's cool :D
[HD2 General] mateuszd:
Hello everyone.

After reading this topic I now can not decide whether to buy this phone or not...

I wanted to buy HD2 from Ebay but if I get a faulty one, will I be able to post it to HTC for a replacement? The ebay seller says it has a 1 year long warranty... Could anyone help me with a simple answer (preferably Yes/No) :)

Thank You :p
[HD2 General] aegidios2:
Hi,

All I can say is that after apply of leo 08787 fix absolutly no trace of screen bug remain, but for some people it doen't work (but I realy think now that is only a software bug) , I'm very pleased with mine now and think that is it a great phone...
[HD2 General] donvince:
I've been experiencing almost all the bugs in my HD2, last month i sent it back to HTC for repair. They changed the touchscreen and display because they thought it wasn't bright enough (i didn't notice that).

I got it back a week ago and immediately saw that i now have a different touchscreen, more dots and diagonal lines can be seen.

All the problems are gone and i haven't been experiencing any problems the last week.

My Advise for people with touchscreen problems, have your touchscreen replaced !
[HD2 General] Batas:
Just like donvince said.

If you apply a patch, you will NEVER experience the HD2 as you should. Just get the screen replaced (Hell! I replaced the whole phone!)

Very happy since.
[HD2 General] Simonnn:
Sorry to bring up the thread again, but I too suffered from all these touch screen problems prior to the patch released by HTC (which fixed everything!)

However, with the current popularity of running Android builds on our HD2s i'm finding that these problems are back again :(

Has anyone found a fix for this in Android? I could not even find any method to decrease the screen sensitivity. I am considering changing my screen digitizer (there are heaps on ebay), but am unsure as to whether that would actually fix the problem.

Any advice would be greatly appreciated! :D
[HD2 General] hoss_n2:
all screen bugs disappeared with the android
[HD2 General] Antimus:
Well I decided to send mine back yesterday.

Been having all of the problems listed, on and off since I got the phone. Sometimes it's worse than other times, sometimes it's not a problem.

I flashed official, unofficial and Android onto it, never solved the problem permenantly, the Hotfix changed the sensitivity of the screen so much it was even more annoying.

I've heard all of the stories about HTC customer support, how the phone will likely be gone for about 4 weeks, which really does suck, but not as much as having to live with the touchscreen problems for another year until my contract runs out.

All I can do is hope that it fixes the problem and I don't get any issues with HTC tech support.

Back to using my brothers old HTC Trinity, blast from the past!
[HD2 General] Antimus:
Well, phone came back under 2 weeks later, can tell the difference straight away. Also, the little dots on the screen are a lot closer together with this new screen, which is obviously what's fixed it.

Can't be happier, if you haven't done it yet, seriously, get it done! no point putting up with a phone that doesn't work 100% when it can be fixed :)
[HD2 General] :
Another similar case. After changing the screen for warranty, the device is working well without any issues such as ghost typing, image shaking, misaligned double tapping, etc.

Seriously, you guys need to replace the hardware of the screen. It's manufacturing flaws.

P/s: using HD2 as secondary phone after iPhone 4.

[HD2 General] axe_1337:
I bought my hd2 second hand, but cant test it on a defect screen right now.

If the hd2 is bought 14 month's ago, is it possible it has a defect screen? Or was it fixed by then?
[HD2 General] trashtakeout:
warranty exchange is the fix?

So basically what everyone is saying is that the only way to get around having a malfunctioning screen is to contact the manufacturer and hope its warrantied OR pay to have it replaced? Is that a correct statement and am I missing any options?
[HD2 General] hahaandroid:
I have nearly all these bugs. i sent to htc and they are ridiculous. they are charging me £300 for repair and £20 even if i don't repair for post and packages. how did you fix yours?
[HD2 General] mark112666:
Did the same to me as well, I paid 35 euros just to get it back from the repair service, appearantly the previous owner opened the phone up. It's just ridiculous that they charge you 200 euros for a known production flaw. I'm going to open the phone up to see if I can do something to fix it, maybe by tapping the digitizer chip a couple of times.
[HD2 General] plainity:
screen not responsive at all!!

i have a big problem with my phone!!

i have the selftyping keyboard and other bugs but today my screen will not responde at all!!

[HD2 General] Mister B:
Sounds like you may need button board ribbon as well as a new Digitizer.
[HD2 General] dontcryjustfly:
Hey Guys thanks for your many answers.

First, i have to repeat...i have my device brought back this monday...how i write it in every second post. So please, don't give me this advice a 10th time.

Answers to you questions:

Rom: Both tryied, 1.43 and 1.48 no difference at all.

Screenprotector: not used...but don't think it makes any difference.

Pressure: After i brought back the HD2, i got an old Iphone 2G from a friend, till i get my new HD2 Replacement. I have no such problems with using the iphone screen at all.

Less Sensitve cab: it don't elliminate or reduce this bugs, except for the painting edge!
[HD2 General] dontcryjustfly:
UPDATE

I got my new HD2 today...ALL BUGS ARE PRESENT! ALSO THE PAINTING EDGE...
[HD2 General] suicidal.banana:
i have had my hd2 for 2 weeks or something, tested all your bugs, and i can only recreate the one about pressing bottom right, but then i have to press pretty damn hard, not like i would accidentally do so.

Then again since u sayd the other bugs arent always there, i will try them a few more times over the next week or so.

Tbh to me it also looks like theres some heavy magnetic distortion going on or something, do you get the bugs despite of your location? or can you possibly track back that the times that it bugged you were in the same location?

Do you live near powerlines, (maglev-) trains or something along those lines? i myself live below a fly-route to a nearby airport (maybe 5km away), and ive never had such bugs.

edit; forgot to vote, voted for painting edge, but i just installed that cab tbh
[HD2 General] adolfotregosa:
well i showed that problem since the 13th of november, i came up with the cab to "help" and i always got the "get a replacement answer "here.. so..i quitted on hd2 because of that.

http://www.youtube.com/watch?v=cFZhWS5jEik

http://www.youtube.com/watch?v=MVgFCV3boX4

I liked the hd2 but coming from an iphone, the hd2 capacitive touchscreen makes me "laugh"..

until a fix (if ever) comes, the hd2 will always have a bad touchscreen.

And judging by the download count for my cab + the bsbtweak that has my settings built in, many many ppl do not like the touchscreen at all.

Htc should fix their touchscreen driver... I never ever thought saying, i'm glad i'm back to using a resistive touchscreen.
[HD2 General] abrelosojos:
For me, I get the occasional non press keyboard typing thing. Where momentarily it will type lots of random letters,

This seems to be if im outside and the weather is cold.

The main issue for me, Is sensitive the keyboard is, Which makes typing generaly a nightmare when your in a car etc.

So I switch to number pad, so it types like a mobile phone, Which actually makes life alot better.

Only issue is, Sometimes I go to type and rather than letters, Its putting numbers in, Although letters are selected.

Only cure for this is to contintue typing with the qwerty keyboard untill it decides number pad is going to work
[HD2 General] Gunzta:
Yes I have the random key press too. Especially when using the delete key lots. Just like in dontcryjustfly's video's.

It doesn't happen all the time. Sometimes it can go for a whole day without issue, then other times it can happen several times in a row. I did notice it happening really badly yesterday. I was outside at the train station. Very cold. I didn't give it much of a second thought at the time but then abrelosojos said it seems worse out side for them. Is this a cold issue ?

hmmmm.. I have raised an RMA with Expansys about this. I was going to Special Delivery my HD2 it back to them today, but then dontcryjustfly said his replacement unit was exacty the same so I thought I would hold fire for the weekend and see what develops. ( I have 7 days to return it to them now) Not much point being without the device for 7-10 days if the new one is going to be exactly the same.

What do you think, is it worth getting a replacement device ? I think I will take the chance that I might get one that this doesn't happen on, BUT the more I read and the more people that come forward and say that have this issue, the more I am starting to wonder...

Do all HD2's suffer from this problem in the right (or wrong) conditions ? or is there a faulty batch out there, because some people are saying they don't have the probem at all.

Is it a software problem that can be fixed with an update, or is it a hardware problem ?

Do the HTC tech guys read this forum ??

Low Temperature or Humidity

I have the same problem with my HTC HD2

I have changed by warranty to new one (serial number +100), but problem still there.

I think problem catalisator is a low temperature (-10 by Celsius in my case) or high humidity.

[HD2 General] Drakknar:
I could just experience "the painting edge" so far, but only when pressing the screen really hard, and in my case it just shows some small dots.
[HD2 General] adult:
For me it was independent of pressing hardness. Some times I even did not touch device and it zoom and draw something by himself.
[HD2 General] Drakknar:
Could you reproduce that only under severe weather conditions or also during normal indoor operation? As far as I remember, even the iPhone3G capacitive screen was less responsive and had some problems recognizing my input when I was skiing in the alps and it was used at similar temperatures (-5/-15°C).

Imho with such a cold weather, the glass screen should become harder and thus by becoming less sensitive it could send to the device wrong inputs. But it could be an hardware issue if it's wrongly operating under normal operating conditions.
[HD2 General] adult:
My original HTC HD2 device does not have any problems at the beginning, but after a week problems was always - out-door (-10°C) and in-door (+20°C).

My new one HTC HD2 (yesterday replaced by warranty) at this moment have problems only out-doors (-10°C), in-doors it is OK.

P.S.: Today, my new one HTC HD2, being half-used, drained battery within 6 hours. doh.

P.S.2: HD HD2 and iPhone have Capacitive screen - this means it is reacting not to the pressing, but to electrical conditions raised by finger.
[HD2 General] xaban:
Guys!

Perhaps we should collect serial numbers from users with and without these problems. To recognize the series.

For people who didn't buy the device yet (like me) or those who are going to return & change their phones. Just to prevent getting a bugged one.

What do you think?

EagleEye2004, could you give your number please?
