Weird spot on the screen

Hi guys,
Today I noticed a very weird looking spot on the screen, or better just below it. It seems like there is some fluid just beneath the surface of the screen. I am always very careful with my HTC's, so I really don't believe I caused it... There was no pressure, I didn't drop it, I carry it in my shirt breast pocket or inside pocket of my jacket, without any other items. I really really dont know what happened - I pulled it out of it's leather sleeve, and it was there. This morning it wasn't.
Any idea if this is covered under warranty? Any idea what caused it?
Best Regards,
Lukas

I'd be STRAIGHT on to my supplier if mine looked like that! How does it look when the screen is on, cos let's face it, that's when it really matters, and probably how they'll view it when it comes to the warranty.

It's difficult to capture on a picture, but it's VERY visible when screen is on. Colors beneath the spot (wallpaper) seem washed out a little, so you get a very small color difference...

Something to do with cold weather and heating leading to condensation? I have no idea but I would ake a photo and email HTC AND your place of purchase ASAP to see if you could get a replacement, even if it doesnt bother you when the screen is on. It would bother me though, I think I havean almost OCD like quality when it comes to devices being perfect...
On a second thought, the leather case that comes with it is extremely tight, I couldn't remove my phone from it for the first few days till it stretched out! Do you think that might be enough pressure to do that to a screen?

I'd definitely get on to whoever you got this from then. That's not good!

call the waranty service ...

Mine had a weird spot as well right in the middle (and it appeared out of nothing like yours). Doesn't quite look like yours though (maybe you just caN't see it in the photo). Only noticeable at certain angles, and it looks like a colorful smudge. With the screen on it's even harder to notice it. When you press on it the "puddle" moves and shifts.
It looks like there is humidity under it. I went to the shop where I bought it, and they said that happens with some other touch screen phones, and is bound to disappear. The guy said it was due to the heat getting trapped bellow the screen.
In my opinion looks more like a humidity condensation thing.
Take it to the shop where you bought it, ask for an opinion. You still have loads of time to use the warranty, and if in 3 or 4 months it is still there or if that bothers you, just activate the warranty.

Thnx for the replies guys!

I don't think it's cold/warm/cold issue... Today I got up, put my phone in my inside jacket pocket, went down to my garage, got in the car, drove to work, into an underground garage and took the elevator into the office - phone wasn't exposed to cold today AT ALL. And it doesn't seem to be water, it's not very fluid, and there is no damp.

It bothers me massively - even when I'm NOT looking at it. The spot is also very visible when the screen is turned on.
I'd definitely get on to whoever you got this from then. That's not good!

Did that immediatly after noticing the spot - my supplier asked me to e-mail him the pictures which I did, but he seemed reluctant to promise a replacement... He said that quote mechanical damage is not covered by HTC warranty unquote. This sucks - I didn't do anything wrong!

Thnx for the reply.
The spot on my phone is really visible, doesn't matter at which angle you look. Screen off is worse than with screen on. There is no color in the spot whatsoever and it doesn't seem to be movable (if I press hard I can make it bigger, but it returns to original size after release)... I'll keep it warm for the night, and I'll see tomorrow... I could measure it, and see if dimensions are changing when temperature rises or drops.

Nope... so no pressure changes either. Good thinking though...

WTF???
When I heat it for about ten minutes with a blow dryer it disapears. When I stop heating it, it reappears @ room temperature... WTF is this thing?

WTF indeed!?! When it dissapears does the display show correctly where it used to be?

Yes, you don't see anything wrong. For about two minutes. Then the spot reappears exactly in the center of the screen (where the 'wait' cursor/hourglass appears) and starts to grow until it has it's "original" dimensions.

Looking at the placement, it seems it's similar to mine, which is right in the center. Mine returns to the center if I press it as well.
The heat test you just did made me believe it has something to do with heat like the guy where I bought it said...
Here is another thread on the same subject (different phone)
http://forum.xda-developers.com/showthread.php?t=293311

I kept reading around, there are reports of the duct tape method.
Basically it works in the presumption the problem is both screens not keeping space between themselves. Just use duct tape over the wet patch, and pull it 20 or 30 times, and the screen should lift and the patch disappear. I'll try it and tell you if it worked.

Thank you! I'll try it as well.

Didn't work...

lol... I had to look for tape, but the tape method was unsuccessful as well on mine.
thnx anyways.

this is a capacitive touch screen so all are glass and the tape method won't work as there isn't anything to lift up unlike the resistive screen where there is a gap between the top plastic and the actual screen

Nexus One touch screen doesn't work properly when horizontal

Hi, I've now used the Nuxus One for a few days and I'm pretty happy with it and all it's fancy fetures.
The phone works flawlessly and the only minor issue I'm willing to report is the fact that when the phone is lying on the table the touchscreen doesn't respond as quickly as it does when holding it in hand..
I've also noticed that if you touch the shell of the phone with a finger while trying to use the touchscreen, everything goes back to normal.
Is it a flaw only present in mine or is it an issue that involves the capacitive touch screen of the Nexus?

Video Proof
This is the video I've taken with my other phone so it would me much clearer what I mean..
The quality is not great but I hope it will be explicative enough..
http://www.youtube.com/watch?v=hXPpyGwuSzM

mine work correctly, try it on another table

I've tried it on different surfaces but the result it's the same..
Problem is that it doesn't always do it, so it's difficult to judge if a surface works better than an other.
I've called HTC support and together with them I've done some tests, like letting another person use it the same way, but nothing changes.
I've also done a hard reset and nothing has changed so I think I will have to send it in hoping they will fix it..
I envy you in the US where you can just ask for a replacement...

Is it possible that your fingers are real dry and or you are working in a dry low humidity environment?

Hi,
I don't think so, since I've now tried it in different environments and by different people...
This is very weired..and annoying..

I've had my Nexus One for over a month, but I recall having the same issue one day early on.
Similarly, I've had days where I can't operate the touchpad on my notebook computer because my fingers were dried out from handling solvents.
I have an associate that has a similar issue when the phone is in a leather holster case. She has to take the phone out on occasion to operate it, most while driving.

havent had any issues. Call them for a replacement

I think I will do so!
The problem is minor but sometimes can be a real nuisance..

Looks like screen isn't grounded properly.

Yes, I think so too. It must be something electrical. When I keep it in hand or touch it, the static electricity must not influence it, but it does so if I try using it lying on its own.

I've taken another video changing the surface on which I use it on..
Take a look: http://www.youtube.com/watch?v=iZ-nS_h5Pqs

I'm glad to see you're still investigating. Because the problem is so repeatable, and the fact that its not a common complaint, I'd conclude theres a something wrong with your phone.
One thing I'd try is to remove the battery for 8hrs (overnight) and see if that make a difference. I've worked with a lot of electronic devices that behave badly after receiving a static discharge. Sometimes leaving it sit without power helps the static dissipate.
But the fact that it works while on the laptop would indicate a poor ground from the touchscreen circuit to the chassis of the phone, as the proximity of the laptop changes the capacitance of the internal circuit enough to overcome the lack of effect that the chassis alone needs to provide.

hehe I have to investigate to be sure this is a bug relative to my device so that when I will send it in for repair they will have to find a way to solve it and not just pretend it doesn't exist...

try pressing with all skin and not with your nail. It needs heat to work.

No, it doesn't. To prove it, hold a metal spoon and slide it across your screen. Mine works.

this was a common problem on the G1 and the way the capacitive screen was designed. In order for it to be functioning completely, HTC told users that he needed to have it in his hand or at least a finger or two touching the phone. HTC said that it simulated a circuit (the hand on the phone made a complete circuit while just touching it left the circuit incomplete) I have noticed the same thing on the N1... it works great in my hand on if i am touching the sides with a finger and scrolling or using it, but if i just lay it down and try to scroll/touch with 1 finger it becomes much less responsive, the same way the G1 would.
i will see if i can find the exact thread over in the G1 forums where all this is posted.

It makes sense, but then, why others work? mmm...

The only thing I found while googling is that you need some humidity in the air for it to work effectively. I'm really not sure if that applies to this specific design though.

I've never had an issue with using the screen on a table, so this is probably isolated, I'd give htc a call and ask for repairs.
Edit: I just tried for the hell of it doing the pinky touch on the frame, and the soft buttons became much more responsive. Hmm

Button light leakage easy permanent fix

This fix might sound crazy but it works
i have 2 evo's version 002 both with pretty bad light leakage under the buttons. One has 3 buttons and the second 2. In the dark they are very visible and i was getting annoying ready to return both. I tried the blowdryer trick but that did not work.
This is what i did about a week a ago, it only takes a minute.
Go get one of this which you might have laying around your house.
http://www.oppictures.com/singleimages/400/SAN82001_1_1.JPG
Go to a dark area where you are able to see the leakage and start painting let line between the plastic and leakage. try pushing down the plastic to and using the pen to paint some of of the inner cover. Get a towel and remove the ink that got into the screen and bottom cover.
After doing this my phone have not shown any leakage. i have tried water in a towel to see if it would remove the ink and show light leakage but no leakage what so ever (do not try alcohol). This fix is invisible to the naked eyes, i have 4 friends with evo's and they could not tell what i did, even after telling them they still did not know where was painted
This is an easy cheap fix, it takes about 2 minutes and anyone (and i mean anyone) can do it.
So please if it make you feel better returning bu

I don't believe i have had a phone that did not have any kind of problems related to software and hardware. The palm pre was a mess every new one i got had dead pixels, after 6 unit i finally got one that had 2 dead pixels. My diamonds phone use to get boiling hot. i could go on. all my friends iphones had drop calls like 20 calls a days (most switch to evo with me).
now the evil have a few problems, like the back cover not been flush and that was solved with a peace of small paper on top of the battery.
You will fine defect, nothing is perfect.

Interesting fix but it doesn't eliminate the fact the leak is happening because the screen is separating. Pushing the screen down will eliminate the leaking. The best fix will be to make sure the screen is sitting all the way down. So far I've only seen one guy do it on androidforums by pushing the screen down with clamps and heating it with a hair dryer. After letting it sit over night he didn't have any more leaking or lifting after two days. We have yet to hear from him on the progress (I think he ended up exchanging it anyway). Another guy said he tried the same fix and ended up making his phone worse.

thanks this is a nice cosmetic band aid If i don't see it, it doesn't bother me as much

yeah but it seems the screen separation on happens the first few days of using the device and the progress stop. my device did not progress after i notice the leakage and was looking for a fix. This kind of fix the problem since you won't see the light leakage at all. The screen separation is wasn't really a problem since i only notice it when the light leakage is visible.

Again the point is missed. This does not prevent the fact that in time the leakage will evolve into screen separating from the base. The light is leaking because the adhesive used during rush manufacturing wad improperly sealed around the face of the device. This was a huge problem for the iphone (didn't think it would happen to me but here I am with my evo)

This worked like a charm I've already exchanged my EVO twice (on my 3rd evo). The first two had dead pixels, and all three have had the light leak. I'm not in the mood to go through the RMA process with HTC, so this fix was a perfect solution for me. I tried a similar fix using superglue on one of the other EVOs I had, but it left an unsightly white residue in the crack of the screen.
While this may not be a permanent solution to the problem with the screen coming unglued, I'm ecstatic that I no longer have to see light coming from the bottom of my screen.
Thanks a lot.

This thread. ... with that Expo 2 ... funny.

I found my own fix after trying several different things including tightening the torx screws, using a hair driver and clamps, and an expo dry erase marker. I read a post about using plastidip which I had, but unfortunately it was dried out. I then decided to use something else I had around. A fine tip black paint maker (Decocolor - LINK). I dabbed the tip on a piece of paper several times to get a little paint on the tip. I then carefully ran it across the edge where the light was leaking which allowed a very small amount of it to drip down in the crevice. I then ran a q-tip and a paper towel along the edge to make sure any that got outside of the crevice was removed. Now I have no light leakage. The paint is permanent, waterproof (not that I will be testing that) and will be easy to reapply if I ever need to. It also takes very little skill and the markers can be found at a local Michaels or arts/crafts store.
On a side note, the hairdryer/clamp method did help a little, but this paint maker did the job the rest of the way.

Screen not evenly aligned on handset?

Okay so I was trying to clean out the dirt in the sides of my phone (the area between the screen and cradle) and noticed that the screen was ever so slightly left and top aligned than centered. In other words, there was less space between the screen and the cradle on the left and the top than there were on the right and the bottom. Not really a big deal, but a sign of poor manufacturing.
Anyone else have this on their phone?

Glad I'm not the only one with that problem, the right side of my screen has a little gap with the bezel, not much, but dust has gotten in there. I'm wondering if I should exchange it and try to get a more perfectly aligned model.

looks like the phone was rush to market with out proper QC

I am thinking about an exchange too, but am waiting for two things:
1) A case and SP to come in to prevent this from happening again
2) To see if this is a common problem

Surprisingly, I think this phone has actually one of the better shields between glass and bezel. I went through COUNTLESS (literally probably 10) Nexus One's with dust under screen (some had failed power button too). Next, the Vibrant was ok, but the following phone, my MyTouch 4G...oh man. Again, went through 5 of them all due to being shipped with multiple specs of dust under the screen. My Nexus S isn't perfect but at least this first one is decent.
One thing I learned..trading in one phone for another can bring unwanted problems. Others are complaining about home/back buttons on the side not working, others say GPS is an issue. You never know what you'll get, so be ready. I don't know how keen Best Buy is on swapping a few phones either.
In my experience though, HTC has far worse QC than Samsung (including the crappy HTC tinny speaker). Ugh, don't get me started on that.

i think you can always go to the store and check, i am sure you will find another one that doesnt have this problem as it seems to me its a manificaturing issue where it screen wasnt placed properly.
not a big deal but for an OCD guy like me. i wont be able to sleep at night till i get a better one lol

Mine looks to be centered, I can't see a difference between the left/right side.

Mine is not off center. But I do have some "lift" on the upper right hand corner (next to the ffc). I can press it down with a little play. Basically it doesn't sit completely flush with the bezel. It's not super noticeable. However the other three corners are fine. Not a biggie but it is noticeable.

Tighten Slide Mechanism

A simple question: is there any possible way to tighten the slide on the DVP? Basically, my top face is a little loose when the phone is in the closed position at the bottom right hand corner. I think it got a little loose when I was prying off the Otterbox case.
I'm guessing not, but I just wanted to know if someone might have figured out a way. I'm getting some screen burn-in anyway, so I might exchange the phone for that.

I'd be intersted to know as well as the screen on mine has gotten pretty loose over time. The screen moves noticeably when pressing on the bottom when closed. This happened just from everyday use.
I'm surprised that you mention burn-in as I didn't think that was possible with an OLED screen.

Not sure on the slider, but slight burn-in is normal on OLED screens. It will go away as you let it sit on the new screen for a while, but it is a part of the organic nature.
http://en.wikipedia.org/wiki/Organic_LED#Disadvantages

my dvp was crappy from day one.
the slider mechanism is cruddy. ive even try to talk some sense into people about how the quality was poor.
everyone just blew me off as if it was fine.
thing is, it was probably loose all a long, you probably just didnt notice it.
most people dont notice these things until something happens to it, then they blame THAT instead.
look at my threads ive created .

I have to disagree, mostly because I remember not having any problems with the slider mechanism at first.
And then I tried to pry the case off to show it to a friend, and did it in a rush, and thus, remember noticing how much it was shifting irregularly.
Everyone's not in a conspiracy to prove you wrong, lemonspeakers. We're just not all going to have the same experience.
Frazzell, I know a certain amount of burn-in is normal, but I have mine set to black out after a minute anyway. A phone conversation with Dell revealed that they do, in fact, cover AMOLED burn in for replacement anyway, so might as well take advantage of it.

If you do exchange it, be sure to test the replacement to make sure it's stable. I had gotten a replacement due to dust and the loose slider, but the replacement locked up like crazy. I ended up keeping the original for now. I am beginning to think the dust and loose slider are inevitable.

Of course--it's the reason I'm not doing it immediately. Really, I think I made the mistake of wrenching the thing with my hands as I tried to pry off the Otterbox case, which is why I think this has happened.
In your first post, you pretty much exactly describe what I noticed (that is, if I close the phone and push the bottom right corner, there's some looseness clearly apparent). However, it's only in one corner. I'll have to give it some thought.
