Digitizer Non Responsive

Hey guys.
Owned the phone for a few months now and have started to notice a really odd problem. For a while the screen was being fairly unresponsive to touches and I couldn't figure out why. Taking the screen protector off fixed it temporarily but now the issue is back.
I finally realised that the issue was a black smudge that would appear whenever I pushed too hard on the screen. I'm assuming this registers as a touch on the screen and prevents it from working. Rubbing the stylus over the area usually makes it dissipate and the screen becomes responsive again, but it would come back not long later after general use.
Also there's some fairly odd rainbowing underneath the digitizer that moves around when you press on the screen. It circles around the smudges when they appear.
I know that all sounds fairly vague, but any help on the issue would be great. Is a new digitizer in order or could it be fixed by just dissassembling it? I've tried using a suction cap to make the problem go away, the rainbowing disappears but slowly comes back again. Also I haven't dropped the phone, left it near anything etc, besides the digitizer problem the phone works fine.
Thanks in advance!
(On a side note, I bought the phone off eBay and had to use a serial number locater to determine the region of the phone. Found out it was destined for India when I'm in Australia. Fairly odd, but what are the warranty implications? Is it still covered?)

Same problem here!
I've sent it to HTC for repair, since my Diamond2 has 1 year warranty and I only bought it in May/09. HTC said that screen issues are excluded of the warranty and that I have to pay about €70 for the screen repair, because, they say, the problem is due to misuse - wich I don't think is true.

You have collapsed your layers between lcd and digitizer.
Some folks here use duct tape to repeatedly pull the layers apart and it fixes their issue for a while.

Thought it'd be something along those lines. I'll give the duct tape trick a try, can you point me to some other threads? I tried searching but was probably using the wrong terms.
Also vasco that's complete bollocks. I've kept my phone in its case the whole time I've had it, never put any pressure on it or had it in a rough environment. I'd throw a few customer complaints their way, especially if other people have had the same issue. Nice to know I'm not alone at least.

The issue is being discussed here:
http://forum.xda-developers...522813
I've already filed a complaint to the comm's regulation office. I'me presently waiting for their response.

had the same issue.. I just replaced the digitizer, it's a bit tricky but certainly possible.. yours is not that old so it should be repaired under warranty if you can have that done (have no clue about your situation there..)
digitizers are cheap on ebay

Here is my thread about this.
I am in the same boat as you - phone was destined for somewhere in Asia, and I am in Australia. I contacted HTC, and they also told me that the problem could be caused by misuse, even though I KNOW it wasn't, as my phone is always in it's case unless being used, never dropped etc. It sucks, but I think I will just replace the digitizer myself.

Help, black 'liquid' spots, what to do

Hi Guys,
This morning I suddenly noticed black 'liquid' spots 'behind' my screen. The screen stills works perfectly, but not sure what to do with these spots.
Should I bring it in for repair (reflashing to original ROM, etc)?
These are spots like we used to see on LCD screens, if you press the screen, they get bigger. If I take out the battery and press from the inside, the spots move as well. I reckon there is some pressure build up in the device and would like to open it myself, but that would void the warrenty of course.
Attached 2 photos, 1 with screen off (clearly visable) and 1 with screen on (not really bothersome).
anybody seen this before?
FTrippie

ink bleeding, u should get it to repair asap, lcd is messsed up
My mistake, the other members are right, I am sorry as I could not see your pictures correctly because I was browsing with my hd2.... it is not ink bleeding, for that, you have to have the lcd broken..... anyway, I am glad is not bleeding, now, lets learn from the other members.... cheers..

There are quite a few threads with people having the same issue, I don't believe it's bleeding like suggested above, it is the layers of the screen sticking together. I had the same problem on my old LG Viewty about three years ago - sometimes it goes away on it's own (when the phone gets hot for example) and sometimes you need to get a replacement. If it's new I suggest you speak to either your provider or HTC.

Use a suction cup to carefully pull the screen a little bit and it should disappear.
Brgds... /TubGirl

Same thing happened to me, and few other members... Have a look here.
Grtz
Lukas

Thanks for the quick response guys!
Yep, it's exactly what happened in thread mentioned
(did some searching but couldn't find it before)
the suction cup idea might be a good one, will check it out and let you know. If I can solve it myself it would be much better than sending it in.
thanks!

(newton ring ) this is dueto great pressure happened on the screen if not fixed in short time the screeen will be corrubted .
note; (it is not covered by warranty)

Nope, in my case no pressure whatsoever. It just happened overnight. If it would be pressure, it would be from a faulty manufacturing and elements of the device not fitting well.
Just read the whole case in the other thread, I think I am in for some treat.
Will start with calling my dealer, which is Vodafone Spain.

mab be it would be from a faulty manufacturing but fix it fast before the screen corrubts from over pressure as this happened on hd1 and they did not want to fix it under warranty

If this happened to me and I couldn't get rid of it, I would go ballistic if HTC claimed it wasn't covered by the warranty. What a total piss take.

i can understand the newton ring effect on resistive screens, but on capacitive screens using glass - i find it hard to believe.

Yes, ardsar. My thougths exactly.
I had Newton rings on my touch hd. And I was informed that that is imposible on capacative screen because it is made of hard material, top layer cannot fall on the lower one.

Whatever it is, I hope it's not a recurring issue. In my thread three HD2 had that issue, and now another one...

Exactly Lukass, I hope this is just coincidence.
I just reflashed the original ROM and will take it this afternoon. In the end I decided not to try to get rid of it myself, since it is now plain visible. And I only had it for 2 weeks, so of it goes.
Let's see what they say.

I had this, repaired by repair service under warranty. The report said it was newton ring.

well, I just brought it in, estimated return is 11th March, let's hope that it will be quicker!
cheers!

Yes it is a newton ring caused by pressure perhaps if you keep the phone in the trouser pocket which is tight.I had the same but as repaired under warranty in 2 days.

Be careful not put to much pressure when putting the battery in, since its a very thin layer between the battery and the LCD. I think this can cause the LCD come in contact with the digitizer if you are not careful.

propably heating issue
has anyone got the idea that this may have been caused by heat? maybe when the internal components of the phone heats up this causes the gap (spot) on the screen. can anyone confirm what is behind the spot? is it the processor? i've got this idea because before switching to hd2 i was using SE xperia x1 and maybe most of you are aware of the cracking issues of the silver casing. well according to my local SE representative this cracking was caused by heating when using wifi. it was covered by warranty since it's a manufacturing defect. HD2 also heats up when using wifi and maybe thats what causing this problem. well its just my idea. feel free to share yours.

i had the exactly the same problem, and fixed it!!!! what i did was to heat it up with a hair dryer while it was on charge(this causes the battery to heat up as well) the spot started to shrink slowly took around 2 hours, but it didnt solve my problem total, as when it cools down the spot would comeback but not as large as b4. so getting pissed of with it i put it on charge from my laptop and placed my hd2 behind the air vent of my laptop(where the heat escapes) and continued working, i forgot my phone was there for about 5-8 hours. when i remembered it was there i moved it, whole phone was very hot not so hot that i couldn't hold it but hot enough. the spot had gone totally. but i thought it would comeback when cooled, so i decided to cool it slowly placing it back behind my laptop but moving it further away at 10 min intervals until it was around a foot a half away from the heat. i now have my hd2 working fine. with no spots.... my theory on this is that the liquid had been pushed else where within the phone as i couldn't see any liquid seeping from the phone so by heating the whole phone wherever the liquid was it thinned and cover the spot but upon cooling it would compress again dont quite understand how i worked around that but it worked

CDMA Hero Bugs and Manufacturer Defects

I'm starting this thread as a central database for CDMA Hero owners to share defects and bugs in Hardware and Software.
My apologies if this has been addressed else-where.
Found with my Girlfriend's and my "with Google" Heros that we both have a noticeable amount of dust under the screen (glass). I thought this was addressed with rev. 2 of the phone?
Anyone one else with the same issue?

paint on case is VERY easy to chip...

I agree the finish seems a little delicate. I've been using a cheap hard plastic case since I got mine in dec. Helps alot with wear and tear, and isn't too bulky or hard to get out of my pocket.

i agree with the paint issue.
my end button is totally red not silver and red

I had a dust issue with my first (unbranded).
The first thing I did with my replacement (with google) hero was to apply an invisible shield to it. I have not noticed any dust under the screen whatsoever.
Also, although it isn't exactly pretty, I found while applying the invisible shield that it did not cover the gap between screen and button pad. As a quick fix to this I cut a thin piece of invisible shield material that was left over and applied it over the crack/screen protector/button pad protector. Just for some extra protection.
For shocks, I have the phone in the HTC silicone case. My phone has taken a number of falls/skids across the ground and stuff and this combo has protected it completely.
Edit:
Almost forgot, my original also seemed to develop a wear mark on the metal button pad finish. It was as if a part of the layer had rubbed off and tarnished in a circular pattern.

about the dust under the screen...
i contacted htc about before. the person who i emailed replied to me saying that htc has a permanent fix for the problem, so you can send it in and they'll replace/clean the screen and apply some fix to it. catch is, you have to pay for S&H and you'll go without a phone for a bit

I have a ridiculous amount of dust in the lower left hand corner of my screen... so much so that part of the screen isn't visible anymore. Do you think Sprint would just let me exchange it for a new one? Or would I still have to go through HTC?

well i e-mailed htc about this twice. the first time they said that if the dust got bad enough, i could send it to HTC and they'd repair it. they also said this:
I understand how frustrating it can be for dust to collect under the screen of your device. We have recently learned that Sprint has a process in place to resolve this issue. Please contact Sprint for the location of your nearest Sprint Service and Repair facility. They are equipped to clean your device, and in doing so will be able to keep the issue from recurring in the future. I apologize for any inconvenience you may have experienced.

That's great to hear! Nice to know it's not like my Mogul was. They just kept giving me broken phones until I bought my hero....

I had heard about the dust problem before, and was glad that I didn't have that problem yet... After reading this thread, I decided to look again.... Now I do have dust in the bottom right
It seems to me that the problem is dust entering between the keypad and the screen, and then getting up underneath of the digitizer which doesn't seem to be against the LCD, which is strange, I think. Most handhelds I've taken apart have the digitizer glued around the edges directly to the LCD. Thank god that HTC and Sprint are actually addressing this problem. If someone does know how and where this seal is applied, I'd love to know. I might be taking mine back before too long, and I always would like to know what they're going to do beforehand.

Seriously you guys should have no problem exchanging that phone in warranty without TEP IF you take it to the shop and they cant resolve your dust issue they will ship you a remanufactured phone.

This is 100% inaccurate. I'm a Sprint tech and there is no process in place for repairing Hero's with dust in the screen. Sure I can take your phone apart and blow the dust out, but it will come back.

Same here. Otherwise no issues.

The stock roms sucks.
But seriously, same as everyone else
-Dust under screen
-Button paint chipping off

At least it isn't near as bad as the Touch Pro. My buddy and I both had one; he still has his... His volume buttons literally fell off, and all of the chrome stripping is held on with scotch tape. The sliding screen has a slight swivel to it. And, thanks to Microsoft, all of his texts are from 1016.
Actually, I'm considering taking my Hero apart and trying to figure out a fix on my own. I think I'll wait just a little longer... just to make sure nothing fails and I can't take it back. Or, is there anywhere I can buy those black stickers for the screw-heads?

I'm surprised none of you guys have seen this yet.

Interesting, I loved my Touch Pro, the only flaking or issues with the aesthetics I had were from where it met pavement once...there's also a .cab file your friend can download that will fix the date issue...I'd post a link but I'm not sure of XDA's linking policies to other sites, just google ".cab fix for touch pro sms date," it's one of the first results.
As far as bugs and manufacturer defects with my Hero go, I've had the phone for a little over a month now and haven't anything to report...it does lag a little at times but I've yet to find a rooting process that works for my Hero for whatever reason, it's the newest version with the "with Google" branding. The "one touch root" or whatever it was titled from unlockr didn't work, nor did the one I found on android forums.
I didn't get stuck in a bootloader or anything for either process, it's simply that neither one had any affect; I did follow both process to a "T." I'll get around to trying the tutorial I found on here (XDA) one day when I have time, although I must say, I kind of prefer the hacks and tricks of WinMo at this point.

[Q] My HTC HD2 is going berserk

Since about 2 months, my HTC HD2 sometimes runs into a strange behavior.
It's like some invisible fingers are touching the screen very quickly, triggering apps, menus, and sometimes calling people!
The only way to stop that is to restart the phone (but when the HD2 starts to behave that way, it's difficult to restart it, as these "invisible fingers" are still competing with MY fingers!).
I don't know what caused the problem in the first place, and I don't know what triggers the problem when it happens.
Is my HD2 out of order?
Thanks
Gz

It could be that your touchscreen is too sensitive and your sweat from your fingers is triggering it; Did you try cleaning the screen, your hands and using a screen protector?

your digitizer is going to die very soon

By "digitizer", you mean the touch glass?
Did it happened to you before?
Why so many of your phones had their glasses cracked?
Thanks

It's very probable to happen...

Try to massage the screen around the corners especially above the buttons.
There is some kind of "glue" to prevent contact with metal but if its old or used it could make this problem.
Maby you can trigger it or at least find the point where to press to make it stop.
=> using a heating fan (warm not hot!) to vaporize water could help too maby. No warranty here!

dertester123 you may have found the real cause of the problem, but I'll have to test more before I can confirm.
Cheers.

i have been having the same problem lately and i must say, i'm pretty sure it's about the sweaty fingers! i have read on other sites that the capacitive (?) screen is too sensitive and that many are experiencing these problems, especially during summer!

Just place some waterdrops on the display or use it with fingers that you put some lotion on....
Problem is when it gets under the display, but thats rather uncommon i hope;D
I case its just just sweaty fingers, what are pants for?

I have the same problem but it only happens in my music app. Could this be causedby a virus of some sort?

are you running android ics? In ics they changed the input slightly i heard, and maby its not ported correctly...
When using another music app or switching to generally other apps while music plays everything is okay?
I dont think its a virus or something, most of them want to spy or change userdata and not annoy you

I thought I had found the cause of my problem, but I can't confirm it, as this problem hasn't appeared since the middle of May, when I followed dertester12's advice to massage the screen on the corners!
But I noticed a spot in the middle of my touch screen where the "glass" seems to "touch" or to be glued to something underneath it. This spot is till here today, but despite of that, the problem is not occuring now. I'll try to attach photos of that.
So to sum it up, I'm still not sure about what caused the problem...

Well the touchscreen must be isolated from the display. Therefore they put some blue glue at the area over the buttons where the HTC logo is. For me I used alcohol to clean the touchscreen as I replaced it and had the problem that when pressure was added the layer of glue was to thin to isolate and gave me fake inputs.
You can test by massaging this area.
Also the contacts on the backside of the screen must be isolated to the housing and the screen. I could think that when you soldered the stock isolation thinned out too..
Last but not least touchscreen, display and housing must be grounded correctly. Therefore all parts are wrapped in metallic foil at the edges... To connect them..
As the touch screen is very sensitive to even little currents its often hard to find the problem as it could also be a totally different cause.
All the above mentioned points should be checked and are relatively easy to fix. But it needs total disassembly what - especially to old devices- has a risk.
Risks are:
That damn flex cables are old and tend to break. The buttons have small tapes on top that come off easily and never go back again... And many more things that break when dis- and reassembled to often.
Sometimes it's cheaper to sell defect HD2 and buy new/used one..
On eBay you often get very good prices for defective HD2..

[SOLVED][Q][Hardware] Screen Seperating from Lower piece with "n" button

The screen section is about 0.5 millimeters above the section of the screen the "n" button is on and now the case on top off each is bending and seperating from the bottom. Its bending the dark gary upper casing. Everything else works fine and I am running CM9 May 23rd Nightly build. I am not the best with hardware and dont want to break this device so I am airing on the side of caution.

To take her apart Google “Nook Tablet Teardown Ifixit”
It took me a few minutes to analyze your problem. I just took apart a Color I got yesterday to repair, but I could not imagine what would cause the LCD to push up. Then it dawned on me. I’ve seen this in an iPhone. The battery sometimes when it goes bad inflates like a balloon. I believe that you need to get a new battery. You can get one on eBay cheap and put it in yourself. If the Color is under warrantee, return it to have them replace the battery.

Tnk you ry much for taking your time to help me find the source of the problem. I got a replacement for that replacement on 05/20/2012. Then that one had the same problem so I got the replacement's, replacement, replaced by a new device (not certified preowned) and a $25 gift certificate for my troubles. I doud that tha many devices were having the same deffect. Thanks for your help anyway! I will keep this in mind though incase I see it again.
For your trouble you get a big THANK YOU and a thumbs up!
