Is this normal?

I have just got my blackstone and I would like to hear from other owners if this is ok
1- I feel that something is loose beneath the camera, when I put my phone on the table or when I tap on the camera from the back I hear as if something is cracking
2- This might be normal but when I tap on the display I feel that the outer cover of the display is a bit moving towards the display, as if there is a 1mm space between the display and the outer cover, this is most noticeable when pressing at the middle of the display
Thanks

I have noticed both of those things ever since I got my HD a month ago. I think it is normal. I even read a tip in the wiki list of tips that deals with the squeaky back cover. See tip Nr. 37 there.

On my device I do not notice anything like you mentioned.

I find:
1. The back cover is loose and makes that "cracking" noise
2. There is zero movement of the screen in relation to the unit. Try taking the back cover off and using the screen.

Really? I notice it on mine but only when I use the stylus and tap right in the center of the screen. It is not much at all, but if feel as though the clear plastic on the screen sinks half a millimeter and eventually touches bottom.
I don't see how taking the back cover off would affect using the screen at all.

Thanks for your replies, my back cover is really fine, I remember trying one in the shop that had the back cover problem but the unit I ordered is not suffering from this. The noise I hear is really coming from the inside and is somewhere under the camera.
Regarding the display, this is not a problem I know but when tapping on the display I just don't feel it is solid but that plastic cover moves downwards. Exactly as Chris is describing above

Doesn't the screen have to go down? Its a resistive touch, so there has to be SOME movement right?

i would recommend going back to the store and ask the sales person to check it
this does not sound alright and mine does not make the sound you described
check "settings" -> "sounds & notification" and disable "screen tabs"" this is a kinda cracking sound too when you touch the screen, and the speaker is on the backside

Oil-like stain reflection on screen

After owning the Touch HD for a full month I just noticed that down the middle of the screen there is something which I can best describe as an oil stain. It looks as if there is a liquid in between the glass/plastic screen and the resistive layer that lays on top of it.
The screen works normally and this "stain" can only be observed if I look at how the light reflects of it.
Any idea what happened?

Hi,
I have a small idear. The TFT-Monitor ist touching your Touchscreen. Probeply you pressed something on your HD, that the two Monitor touch each other, that is why it looks like a Water or Oil spot.
This can happen for example, if you are carrying your HD in your trouser pocket.
If you want to try to remove this spot, you have to turn with your both hand the hd, like the right hand turn with the clock and the left hand turn to the other way.
Sorry, my english is not very good for such a discribing. What I mean is like "to contort" or "to skew (up)". But you have to be very carefully. Before you start, remove the Battery

(I'll be incorporating a clearer explanation along the lines of what Dude10 was trying to say)
The effect you're seeing is IDENTICAL to what causes the colours to appear on an oil film actually!
The way the Touch HD screen works is to have the hard glass (polycarbonate plastic actually as far as I'm aware, but that's not important here!) with a squashy resistive sensor layer on the top.
This resistive layer detects touch as an increase in resistance at the spot that's compressed - be that by a finger or a stylus. Because the upper layer can be compressed, it can also be malformed by stronger than normal pressure, such as an object in a pocket. The effect can be more pronounced if your body heat warms up the screen surface making the screen "set" in position rather than spring back as it should do...
The "oil" effect is cause by the reflections of light from the outermost plastic layer and the outermost surface of the hard screen. When the gap is small enough, these reflections can interfere with each other, cancelling and re-inforcing different wavelengths depending on the thickness - hence the tapering of the screen from thinnest to thickest results in a "rainbow"
Now, why explain all this you may ask? Partly because I like science and it fascinated me in school to learn what caused that effect so wanted to share this! (And this also explains why it only presents itself when you look at the light reflections)
Anyway, more importantly, the solution to your problem is to restore the thickness of that part of the touch layer to it's original uncompressed state.
I'd firstly start trying to hold your finger flat against the top of the phone screen (on flat surface, portraint orientation, finger "left to right") then pressing resonably hard (the hard screen should protect the device - if not you're pressing too hard!) slide your finger down the screen from top to bottom trying to keep an even pressure. This should hopefully even out the surface.
Failing this, as Dude10 suggests, take the battery out and use your thumbs (holding with fingers in the battery well) to press and "smear" around the problem area.
Unfortunately, other than this I don't think there's a particular way to remove the effect totally if it doesn't work...
Obviously it's speculation given that you didn't mention how it happened in the first place, but it does sound like it got knocked or pressed by something either in bag or pocket - maybe even a fold in the pouch
Hope you manage to smooth it out!

Just a long shot, but:
Sometimes a similar effect can be caused when some moisture has got between the layers of a display.
Have you used the phone anywhere damp or very humid ?
Keeping it somewhere warm and dry might be worth a try?

Thanks for all the tips. The issue happened when I had the Touch HD in the pouch and in my pocket - so the idea that it was a fold in the pouch holds water.
The funny thing however is that before I saw all of your replies I was already out the door (with the Touch HD back in the pouch and pocket). 5 minutes later when I pulled it out the issue was gone. I am guessing that I reapplied the exact amount of pressure needed or something like that.
Thanks again for the tips and especially to chaosdefinesorder for the nice explanation.

Thx for helping explanation

5 minutes later when I pulled it out the issue was gone.

no, i don't think it was gone. check again under a fluorescent light....
i have this on my diamond. my HD is flawless (till now...)
i phoned to a technician and explain the phenomena and he invited me to replace the screen. when i got there, to my complete amazement and embarrassment the stain was gone. only later i discovered that the stain is visible under fluorescent light only.

thanks m8, already tried this (on my diamond) and tried now again with both yr methods. no results. the stain is still there...i think only a replacement can solve it.
here u have the paralel thread in diamond forum:
http://forum.xda-developers.com/showthread.php?t=439410&highlight=oily+stain

you can not do it yourself. the best way will be to go to your seller or straight to HTC, because I think you HD still have warranty.
I repaired ones an Diamond and I can tell you, it wasn´t an easy way.

MY HD2's Capacitive screen can do things on its OWN! WEIRD!

I am not much of an expert on this but I suppose capacitive screens respond to some sort of voltage (Like from your fingers).
If my HD2's screen is ON and I lay it face down (Say while in the photo tab), it can actually do things on it's own such as play a movie, or open a picture.
It's very weird like that and I don't know what could trigger it to do that.
This happens on paper and cotton cloth ( the only surfaces I've place my HD2 on).
Can anyone explain this phenomena?

its a ghost

open a new note and try to draw a straight line by using something for a ruler.. like a cd tray, or a pack of sigarettes etc..
the line will not appear, but beneath your ruler there's a messy drawing..
I think it's like you say, electricity... but I'm not sure..

One can't help but wonder what would happen if you put it near one of those "lighting balls" that output static elctricity...

You need to send that back to wherever you got it from straight away. It's knackered and will always be knackered. If you don't send it away to be replaced that you'll be stuck with a useless device.

Attention with clicking screen and dust under it !!!

Hello,
I got my N1 1 week before, and i'm really satisfied with this phone.
Since the first day that i got it, i tested it by applying pressure to the corners of the screen, just to check if it had any problems of clicking screen like the other users reported, and it was ok, no clicking and everything normal.
But today, i tested it again and i noticed that it clicked near the touch buttons at the bottom of the screen I applied pressure on it, and it seemed like it glued again and didn't click anymore, after several hours it begun to click again
I think i will apply the hairdryer method, before dust goes under my screen.
I just opened this thread to warn the other N1 owners, to check their phone again, so you are all sure that you have no problems with your screen.
Best Regards!

What's with this clicking?! I don't understand where you see the problem

Thats a good point cause I just got the N1 couple of days ago and noticed a clicking sound on the top area. Didn't know this was a known issue. Gonna have to look into it further.

I tried telling you guys in the thread I started (the other one about the dust under the screen), where I first suggested using a hairdryer... that everyone should go ahead and warm up the screen and make sure it's sealed properly. The glue has to be warmed up well to really get tacky so when it cools it will stay sealed since it's porous.

Yeah I did something like that. When I was leaving work I figured if I crank up the heat all the way up and hold the phone in front of the vent it might achieve the same thing and it seems like its good now. I don't here any clicking any more. I actually realized it was clicking from the bottom area as well aside from the top but it seems good (hopefully).

What exactly do you guys do to get that clicking sound? You press the edges of the screen? Applying a lot of pressure, or the usual? I don't seem to be getting anything weird, but I'm not pressing too much either.

You have to press at the corners with a good deal of pressure to hear the clicking.

Hm, I don't seem to be getting any noise. Is it loud, or barely noticeable?
Also, if I start to hear it in the future, is it an indicator that I might get the dust problem? Should I heat it with a hair drier? Won't that melt the plastic parts of the phone?

Press hard then let go and you may hear a very faint click. You have to listen for it. If you hear nothing then I guess your unit is fine.
Hairdryers shouldn't melt the plastic components, but should be hot enough to warm the adhesive up.

Ah, sounds like breaking the glue under the screen or something..
I used the hairdryer and it seems to work for a short time on the 4 softkeys.
Will try the upper part now

Did the hairdryer thing a month ago and its still holding strong

This message was deleted by its author

I am having trouble with this, after reading this thread I noticed the 2 bottom corners of my screen do click when pressing down on them hard, so took out the hair dryer and did each corner for about 2 min on full heat full blast, screen was hot to the touch, applied firm pressure while it was cooling afterwards, and there was no clicking at that time.
Now afew minutes after it is still clicking.
How did you guys do it exacly?
edit: nvm got it, had to hold down harder and right at the edge of the screen.

Yeah Mafi0s0, thats what i did too. I realised my screen clicking again after doing it the first time. Doing it the second time - it required alot of pressure, but doesn't seem to clicking anymore.

Thanx for the tips guys, I also had the same problem, but applying more pressure fixed the thing.

Mine also had the clicking at the bottom, and i have some dust under the screen.
It fiexed for now .. but i will probably disassemble it to clean all the dust if it gets worst.

This hair dryer method hasnt worked for me at all, I have tried 3 times, I just checked then and the clicking is heaps bad, its very loud. I am gonna get dust under my screen for sure if I dont fix this.
How have you guys who have been successful done it exactly?

Today I noticed 2 very small dust particles under my screen. After seeing this thread I did the corner test and it turns out the the bottom right of my screen clicks. I did the hair dryer trick and it seems to have fixed it.

Front screen only GLUED on? It is popping off!

Okay, I read that someone lifted part off the front by removing a screen saver! Now with me, I recognized that on the left side bottom, left to where the slideview and call buttons are under, the ENTIRE part seems to come up.
It is lifting itself and I bet in a few days/weeks this will get off.
So my question is if anybody had this happen and knows what is under there? Is there a possibility to GLUE it back on?
Now since I am watching this, I think the ENTIRE front can come off eventually and if it is just glued on at the bottom where one has to press the buttons all the time, it is only a matter of (short!) time until this gets out of hand.
Anybody found anything about taking this phone apart yet?

That happens to my phone, I do not bring it back because I buy it in a duty free shop here it japan and also that is the only issues on my phone and only some bugs. I just press it always there to bring it down but it keeps popping up. I think i can glue it, so I do it to fix the problem. Just be carefull if you do it, I notice that under the plastic screen there are buttons (as I think it is) the hard part that you feel when pressing the slideview or call. When you use a liquid glue and put to much, it can go to that button and worst may stuck that part or go inside the phone and also the part where the mic is. I put glue just on the sides just make sure to put small amount at a time. I cannot give the brand of the glue that I use because its in japanese.Now only the small part in the call buttons is up a little because I cannot put enough glue on that part, but in the slide view button its now okay and working well.
This is my firts post on xda hope it helps a little.
