Annoying shadow appeared on my screen:(

Happened some time last night I guess, it looks like humidity between the touch screen layer and the screen. It does not affect operation of the stylus, but does leave some ghosting effect when the drawing contrast is high - like when drawing the cursor on ScummVM. Highly annoying, the PDA is still under warranty (have it for 5 months) so I hope it will be a good enough reason for replacement. I have a screen protector always on, and an aluminium case so I hardly believe this could be my fault at any level. Any opinions?

hmm
still there after removing the screen protector? :twisted:

haha, yeah. I thought about that too. It's, unfortunately, still there. The photo is with the screen protector removed.

How about trying a hairdryer on it low setting mind you it works on condensation on watches should be no different. :idea:

Tried it. Doesn't seem to affect at all the shape or anything. Didn't insisty too much so that I don't melt anything Also, when shape doesn't seem to be affected by the push of the stylus, so maybe my original estimate of it being humidity is not correct after all.

Looking at it again it looks like a pressure mark like if you push the screen to hard not sure what you can do about that but good luck with it.

Well, you might be right. I hope it is covered by warranty, it's been only a few months since I bought it How much would a new screen cost me anyway?

Think I saw one on ebay today £79 I think but dont quote me.ebay id 9707065454

I had that on my screen when I would keep the wizard in my pocket, pushing the screen. It would go away after a few hours. It doesn't seem to do it anymore though... the screen must have aged or something.
Thanks
JK

I am pretty sure I didn't bend the phone in any way. It is always in an aluminium case that doesn't bend And it hasn't gone away yet, it's been many days now I think I am screwed. Do you guys think that the warranty will cover that?
Edit:
I definetely think it's some kind of liquid, most likely water from humidity It's pretty humid here in Edinburgh at nights. The shape seems to alter if I press near the shadow, and after some presses, the shape has changed a little bit. I might try the hair-dryer thing someone proposed a little more, crossing my fingers that I don't melt anything. I will let you guys know how it went.

Is this really true?

Someone is selling me his 2nd hand HTC Universal.
He told me it has minor scratches and a small crack just below the front vga camera which, he told me, is "normal" to all units.
Is it true? Is that spot under the camera really prone to cracks?
Thanks for your replies!

I think it's usual.
My uni is broken on the cameras glass.

None of the 4 universals I've had have got this crack, they were all pretty battered and scratched but no cracks.
My current one is probably the worst with several dents but still no cracks.

Hmm...
That's strange.
Anyway, thanks for your replies.

It is true
almost every JasJar I saw had the crack on exactly the same spot under the VC camera, it goes from the corner of the screen down. Another similar spot it right up from the stylus tip towards the hinge. Somehow Execs are less prone to the same breakage. Usually happens when the screen is replaced or someone attempts to open the screen without proper tools or knowledge. Wizard has a weak spot like that next to stylus as well, I guess each device has its very own weak spot.

Thanks for the heads up. I guess I'm buying the unit afterall.
I'm choosing between the Universal and the Asus P526 and I'm really confused.

If you wants GPS go for ASUS, but without keyboard i will prefer the Uni

Hmm.. I don't know how to use a the GPS feature anyway.

Ah that could be why I've never had it - I've never tried to take the screen off...

just had a look and mine also has a thin hairline crack in the plastic on the videocam corner - never noticed it before!

No issues on my second hand one....Sounds like you want to look at a body replacement as well (skin/body cover)

That is exactly the place - have 2 units with that exact location of the hairline crack. Too much of a coincidence I think. Another one, as I mentioned, usually appears just above the stylus handle, extending from the hinge down. Third appears on the keyboard part itself right at the swivel hinge. Might have to do with the usage and practice of opening and closing the screen. Have one unit waiting for a new case because of the cracks. Might go black O2 on JasJar motherboard, O2 screen and O2 blue-lit keypad.

touchscreen defect?

hi there!
i got my touch hd last week and i have sth i wonder about if it is right or sth like a defect:
the touchscreen works great and its everything ok with it... but:
it seems to me that the touchscreen is sth like a foil that recognizes the inputs/pressure. fo safety reasons and to keep this foil from being damaged/scratched, there is a thick(er) plastic foil over this first "touch-foil".
on my device, the seems to be some space between these to foils in the middle of the screen. sth like ~0.5mm or so.
the effect is, that (my touch-sensitivity is set to max) touching a control at the SIDE of my screen very softly leads to imminent touch-recognition, while in the center of the screen there is this "gap" between the foils so that one has to push the upper foil down these 0.5mm until the touch is recognized.
acutually i can really FEEL that i have to push down the outer foil until the touchscreen recognizes the input...
i checked another hd-device (the one of a friend) and his device did not have this "gap".
is this a defect so i should return my device to htc for repairs or is this a common thing and nothing to worry about?

Hello,
I have the same "gap problem" but I think it is supposed to be like that.

even this phone from this friend mentined does not have this spacing? i'm anxious that this is sth thats not right...
anyone else here with the same sort of problem?

I have the same problem with the screen

HD has resistive touchscreen which has very thin layer before glass. In bigger screens, like HDs it has small gap in it.
Some older devices had way worse problems with this, like my wizard it felt like 1mm gap sometimes.
Try to live with it, its more like feature in resistive screens
Go for iphone if you dont want it.

The pressure in the touch screen should be uniform, but in some units it's not.
If you can, you should replace (not repair) it with a new one.
In my unit it's harder to press the uppper corners with the pen, but its a small diference, I have to make a bit more pressure (less than double pressure).

Hi, thats exactly the problem I have on mine (specifically the upper right where the Close button is)!! Mine is only 5 days old from Orange. Do you think I should get it replaced? When typing texts etc the 'keyboard' feels spongy - I am guessing this is the gap people talk about?
Thanks for any advice.
Rich

This is not a defect...it is just the glass screen is installed on different ways...my has some 0.1mm gap in the middle..but almost nil at the side..
But if your gap is around 0.5mm, I understand it is quite annoying...go and replace it but test the new ones first...
It is luck dependent..
you might get bad pixel(s)
Duffy buttons
peeling paint
flickering display
Mine is quite perfect... since I bought it to Fortress store in HK..and opened up at least 5 units and chose the perfect ones..
BUT I stayed there for almost an hour ..checking..

Thanks for your reply. I have just received a replacement from Orange today and the screen seems a bit more responsive however it rattles when its in vibrate mode so I am getting another one tomorrow evening. Orange have been very good about this I have to say.
Thx again
Rich

touchscreen does not "untouch"

Hi Folks,
I'm reading this forum since about 1,5 weeks, as I got my first smartphone then. Unfortunaly I sent it back today, as it got broken yesterday. It has the problem, that the touchscreen doesn't untouch. I made a picture:
I can get rid of this touched area by pressing on it with my fingernail and move it to the bottom.
I think it's from that lether case. Anybody else ever had a problem like that? Probably with another phone type?

Looks like condensation under the screen to me.

Reapply screen protector... That's it..

I thought about water also, but under the microscope we have seen that it wasn't water. I was able to remove it restless until I touched it next.
I removed the screenprotector, but that wasn't a solution.
Unfortonaly I had to send it back today, as I'll get a brandnew one within the first 14 Days after delivery

Wow that's new. Mebe condensation.
Maybe since the touch part is 2 layers, Glass and Plastic screen hovering on top of that, that it got too hot somehow and that the plastic part got stuck to the glass. mebe if you had let it cool or something it woulda unstuck.
Was the phone near any heat or in direct sunlight?\

This looks like a cracked digitizer, a touch sensitive layer above the screen itself. The screen underneath usually seems to be fine, but it doesn't have the touch capabilities anymore. It has a look of spilled liquid and you should be able to see dots of the touch grid, you can't see them normally. It happened to me on my Orbit2. I think whole screen has to be changed...

I thought about something like that too. Has the digitizer a "spazial" filling, so that you have a "soft feeling" when you tab it with the penzil?

I had the phone in my trouser pocket every day. No sunlight or heat. I tried cooling down...no chance. I had a Cassiopeia once and had a waterdamage to it. There I was able to get the water out of the touchpad by having it on my heating for a few days. But it looked not like this here.

i have removed the screenprotector but is the same error, i have sended it to assistance center this afternoon...
i wouldn't pay for damage why the phone is never fall
i hope well

Just had the same problem with my Td2. Not impressed. The phone was fine one minute as listening to my music on it, popped it in my pocket went upstairs ang got this blob right in the centre of the screen.
Glad I took the insurance now as this is going to have to get sent back. Not overly impressed as only had the phone for 6 weeks and having a problem with the build.

Just a quick question for those that had this problem. Was the damaged screen visible under all types of light?
I ask this because taking into different rooms in my house and different types of light it seems to disappear, then reappears under other light sources. I will test in the daytime tomorrow but am now starting to wonder exactly how long it has been there...

My "blob" couldn't be seen when I looked straight from above. As on my pictrue I had to look from a angle to see it. Also it was hard to see under bright daylight. Hope that helps.
But I have a question also: You all used the leather bag shipped with the phone? I think the case isn't plain enought inside. I think there is a higher pressure one the display while wearing it in my trouser pocket. Anybody else who can tell more about that?

I've the same problem, at least I think it is the same. Touch still works fine, but it seems like there is some condensation underneath the screen.
I can confirm that it has nothing to do with the screenprotector.
If I put my finger on it, it moves to the sides. Sometimes it seems to be gone, but after a while I notice it again.

As you are the 4th in this thread I think so

It's not under warranty of HTC, at least that's what they told me...
Did somebody else contacted HTC about this problem?

too bad it seems like they classify it under 'cracked display' - and according to the user manual it is not covered by warranty.

Probably, but I think it's just an error of HTC. The way they treat their loyal customers is, in my opinion, verry disappointing. It was the same with the problems everyone had with the TytnII.

Today I got my phone back from my provider...the same broken one. In the letter they told my I sent it back too later
Now I'm dissapointed from o2 Germany, cause the customer support told me what to do and I did it.

guys i had the same problem (http://forum.xda-developers.com/showthread.php?t=519441) and i got a replacement. but i tell you.. this is caused because one time the phone got hit by pressure on the screen and the screen itself kinda felt into the phonecase. check out from the side.. you probably will see that the screen is lowered - then when you use fingers on the touchscreen this blob appears. in my case the screen didnt work anymore as soon the blob appeared... but was able to get it out with some tissue and rubbing.
also i saw some oil liquid under de screen - depending on the light outside.
so.. just take care.. this phone is very sensitive to any pressure on the screen and using it in a trouser pocket is already dangerous!

Help, Newton's Rings! (Oily rings appearing beneath screen)

I've heard of this problem happening on other devices (see here, here, here, and although not what mine looks like, here), but I was wondering what I can do about this problem. This is called Newton's Rings, I believe, and there's a nice wikipedia article about it. Apparently it's a problem under the screen.
It's an oily smudge. It appears to be made up of asymmetric rainbow-colored rings and is apparently under the screen. It is only visible in indoor lighting in certain angles, and is less visible when the screen is on. When pressure is applied around this spot, it appears to shift slightly. It's been present for over a week on my device without much change.
The HD2 has a capacitive screen, so the method to correct these spots (the "duct tape method") is said not to work. How can I fix this problem? I'm pretty sure I didn't cause it since I was careful with my device--it could have been there (most likely) from the time of purchase.
Should I ask for an exchange at my local T mobile store? Should I try duct tape or a vacuum cleaner to suck the screen forward, or should I try to open the device up and detach the screen, or should I beg for a return?
Help!
PS: You might want to check your HD2's as well...

*deleted*
*deleted*

I think you would have to have a resistive screen to even have this problem. A capacitive screen doesn't have these "layers." And, it requires a curvature to induce the inference rings which a hard glass screen with no layers doesn't have.

I followed a couple of them threads some time ago, and if I remember correctly some users which had this problem you're postin' about have had their hd2 replaced by htc cause it should fall under warranty terms. Return it to your local t-mo store and ask for a replacement. Should they deny that, try calling htc customer care and see if you can send it in to corporate for repair/exchange. I'd recommend that you try official ways first before attempting to disassemble it or to fix it by yourself as you may end up voiding your warranty..

Since you have a US T-Mobile HD2, and it has been less than 14 days and within the return period, you should be able to get it replaced at the store.

This is obviously a problem with the screen and you shouldnt try to fix it in any way. If you have installed or modded it in any way then return it to stock condition and take it back to your store. They are obliged to give you a replacement as it is a faulty unit. do not accept anything less.
Mark.

First of all, why in the hell would you buy such a device with incredible screen real-estate... and NOT place a screen protector on it?
My screen hasn't even been touched by human hands. Let me guess, the next thing you're going to tell us is your device has a scratch on the battery cover...
Having a case on the device would have prevented such an incident from occurring in the first place. Problem solved.
Take better care of your investments folks...

I seem to be confused about why you need a screen protector when the screen is glass? I was under the impression that glass screens won't scratch. I can't see how a screen protector would protect a glass screen from pressure, so what's the point?

LOL TRUE!!!!!!!! ^

Alright, well... I'm not even going to dignify myself a response to your first question... for obvious reasons.
As for pressure... what PRESSURE could you possibly be applying to your device that is apparently going to render the screen useless? It's a ****ING Pocket PC, don't mistreat it. Protect your investments... it's common sense.
Seriously though, your first question... RETHINK exactly what it was that you had asked me... and then I'm pretty sure you'll realize the stupidity.

I don't get the attitude, I simply asked you, or anyone else who seems to think they need a screen protector on a glass screen; why they feel that way. As far as I know, it's like next to impossible to scratch it, (unless you carry loose diamonds in your pocket) and the pressure comment was me trying to understand why you feel the need to get a protector. With all that said, I wasn't knocking you wanting one (somebody's got to buy them) I was simply trying to see if I was misinformed about the durability of glass screens.

Heh, my bling-bling may scratch my phone screen That's how you can tell they are real diamonds . Though, you make a good point, glass screen shouldn't scratch, and if anything, a crappy thicker screen protector may hinder the conductivity of your fingers? Just my guess. On a side note, had my ipod touch in the same pocket as my keys once (hate the thing, but it was free) The back got scratched to hell, but the screen was nice and unscathed.

Alright. Well, my apologies for the "disrespect".
I'm merely saying that a screen sleeve, protector, or WHATEVER is how someone could go about preventing the oil corrosion that occurs from natural skin oils on the screen.

This isn't oil corrosion. No disrespect from me either, but this unit actually had a screen protector. And a case. So thanks, but no thanks.

I had exactly the same situation with my old Hermes (going back quite a few years). I got it through the post from Tmobile and was playing happily with it for about half an hour until I noticed an oily patch exactly as you describe. Rang up Customer Support and they asked me if I had sat on the phone or knocked it in any way.. And this was after having the phone in my possession for 30 minutes HAHA in the end they told me to take the phone to the nearest store to confirm the problem and I got a straight replacement.
I think its caused by a leak in the LCD. You can try, as sugested on other threads to get some tape and try to pull the glass away from the liquid but this would only really be worth trying if your phone was out of manufacturers warranty. Since you have not had your phone long at all you are entitled to a direct replacement under the Sale of Goods Act.
Going back to earlier posts, too much pressure could cause this sort of problem but as stated with a good quality glass which the HD2 has this is very unlikely unless you had an elephant sit on it
More likely the LCD is defective and if the oily patch is noticeble to you then the seller has no other recourse. If I was you I would deal with this matter as soon as possible though so that you get a stisfactory result.
Mark.

Hey guys.
looking at your device, you have the same problem i have on my HTC TOUCH HD, mine had a small point in the middle, and after a few months it become bigger and now my screen wont work properly.
it means when i perss lets say "START" button, it reacts at the X button in the right of the screen.
adter looking over the net and reading about it, i can see a lot of devices from HTC has this problem, guess its a bad building quality who knows.
maybe it got hit a few times at the screen, maybe pressure who knows.
the thing is, CHANGE THE DEVICE before your screen wont react anymore, mine is Resistive screen. so i took a small niddle and lifted the screen from the left (the volume side) and squeezd it a bit, it went out, but a bit more came back after, that means something or some fluid is between tha screen, the Gap maybe i dont know.
ive also tried with a DUCT TAPE - worked for a few minutes than it came back again, but even when the oily part was gone the screen still was reacting not as before.
also there is a bad sound from the place you have the oily part under it' like if you press it with the Stylus or just your finger.
BE CAREFUL with thos devices!
Also ive heard something about PRESSURE differents between cities / countries and simillar can cause the screen defect.
for example - i live NOW in Eilat, its in Israel, and its a very very low place, i go home once a month, to a higher place (300M above), and it happaned since i moved here. it can be one more of the reasons to cause this defect.
well, my device is ruind, it can barely work now sometimes, if i press the screen from all of the sides or lifting it up with a niddle!
and that sucks!
BTW USE YOUR WARRENTY.
dont let HTC run away from their defaults and defects with thos devices, why do we have to pay on their mistakes of not making a good resistance materials for thos devices...its stupid.
specialy when it happanes to a lot of people with the same Devices!
i dont see any APPLE users having thos peoblems with IPOD / IPHONE!

All touchscreens suffer from defects (yes even ipdods and iphones lol). The trick is to send it back the moment you spot it and not sit on it and wait, hoping it will go away. It wont. You can use the tape method to pull the screen away from the bleed but the liquid will still be there and sooner or later it will just come back.
I noticed a bleed on my OLD hermes the day I got it from brand new, rang up the shop (tmobile uk) and they tried to tell me that I must have sat on it or dropped it. Everyone who purchases a device has a right that it will work for a 'reasonable' amount of time without defects appearing so you have to push your rights and get it changed (not fixed) for a new device.
If your device is out of warranty and you have a bleed on the screen the only thing you can really do is change the screen. These can be found on ebay and not that hard to do. For your Touch HD you can get one *HERE* but you have to weigh up whether its cheaper to just buy a new device or fix the one you have.
And I dont really think atmospheric pressure between different places would have any affect as lcd screens are built to work pretty much anywhere and if that was the case every time someone got on a plane their device would go capput.
Mark.

i know! that sounds not reasonable, but i looked at someone's Thread about that he went out of a plane and he noticed a huge spot in the middle of the screen, and few days later after going back on the flight it was gone.
that thing is very strange.
btw thank you for the link..
