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.

why does the screen "shivers" when i place my finger on it...

i have applied the de-sensitive cab but when i use my finger to press down and drag selections, i can never be precise .. the screen starts to "shiver" around like Jack from the Titanic ...
hmmm is there any tweak to reduce this?
BTW, do i need to align the screen regularly?
thanks!!!

appreciate any help on this

I too have the same problem. I have read the other exhaustive thread on screen problems but couldn't come to a conclusion. Is this a software issue or hardware fault?

Do you mean the built in tactile feedback vibration where the screen buzzes to let you know it's been touched?
Settings/Personalise/Vibration/and then uncheck the box

Try the screen sensitivity reducing tips, or better still use BSBtweaks, it has a toggle to reduce sensitivity that works.
also, i found being too gentle with my fingertip makes it juddery. a firm press with the pad of teh finger works better for me than the tip.
I align my screen after any hard reset / rom flash.

i had this issue too, it appeared suddenly a few days after i upgraded the radio on my previous rom. with the current combination everything is in place now.

I would say it is a hardware fault. My first HD2 was perfect with no screen sensitivity issues. Unfortunately, it was accidentally damagaed and I had to replace it. The replacement unit did suffer from the sensitivity issue and although the sensitivity fix improved things substancially, it it still wasn't anywhere near as good as my original unit. So it went back to the store and they game me a replacement which I am happy to say doesn't have the sensitivity issue and is a joy to use again.
The new unit does however have an uneven backlight but I'll probably live with that as it's the lesser of two evils!

omg why cant they built it right one time!

Are you guys using a screen protector?
I used to have perfect screen behaviour. Recently, I saw the multitude of cheap 3 for $x screen protectors, and tested about 8 different brands.
Some were pure crap, didn't prevent fingerprints or oil...
The mirror ones and some clear ones killed sensitivity!!! Made my touches jump all over, my presses inaccurate.
Some matt screen protectors were too thin and were absolutely useless (and easy to scratch).
Only a few were good enough not to cause a problem.
Can only suggest you try remove the screen protector if you encounter the same issue.
Cheers

Unfortunately this is a known problem:

Getting the device changed has helped to reduce this in some cases.

i was trying out the iphone, i noticed
iphone screen is matte.. no stickiness if sweat and swipe is smooth..
hd2 glossy if you sweat, you get friction... swipe depends on friction
if i were to put a matte screen protector, maybe it helps? anyone knows about this?

IPhone 3gs and HTC Hero both have an oleophobic coated screen which greatly reduces fingerprints and smudges. HD2 does not. Don't know why HTC don't use this tech on all of their capacitve screens.

ok i used a matte screen protector... result = smoother flicks and less finger prints.. but shivers is MORE...
hmmm what is wrong with our screen? * i tried iphone... NO ERRORS in typing..
could it be our software compensation for errors is screwed? u know as in the software is predicting the center of the finger wrongly

Problems with the screen illumination of HTC Desire Z

Hello, I change the screen to my Z and I have this problem.
I noticed the screen flicker when you touch or press the edges of the screen / phone. It's like if you increase the intensity of light.
The display properly reacts to the pressure of the fingers, sliding screen keyboard ...
What can happen? The screen? I open it?
The 2 Connectors of the screen with the board?
Thanks

are you using auto light? if yes try to disable it

I'm guessing it's an issue with the connections. Are you using too much pressure on the screen? I've never seen that happen on mine.

I think this is, I will dismantle it and see what happens.

Repair fail !!
Well I'm back to open the Z and I've broken the screen.
I get those lines and a black spot. 25 euros lost.
I hope it's only the screen and the digitizer.

this happened to me now i cant get anything but the lowest brightness
if you have the same as me its not the screen i think its the cable but i cant find a cheap replacement to test it plus i am thinking of going to the droid 4 if/when it gets its gsm update

Did you manage to fix the problem with your Desire Z screen, I had exactly the same problem after replacing the LCD. I took it apart and put it back together again & again but couldn't find what was causing it.
I think when you take the screen out the first time, you remove that clear glue stuff, and probably make it slightly loose. So what I did was take some of them sticky labels for printing. With a scalpel cut some very thin strips (about 2mm in width and almost the full length of each side), folded them into an L shape and stuck them aroud the 3 edges of the LCD, before sinking it into the housing and the problem is fixed.
Just in case I've not explained that very well, here is a really bad diagram.

Nokia 6,power / volume buttons question.

Hello,i don't know if this is correct section where to describe this problem,but anyway is just an question so let it go.
Like title says,on Nokia 6 there is a problem with buttons design or i broke them ? Because i can see the backlight from LCD through power button,its just a very small space betwen aluminium body and those button,
where you can cleary see the light from screen.
I observed this after i did an hard reset,and i pressed maybe a bit to much power + volume up buttons,but they're working fine.
Also remember,in order to check this for me,do it in a dark place with LCD brigthness at least 50%,and move your phone whille looking at those buttons,you can only see the backlight from two differents angles,at least on mine.
So please check and report back to me,to know if this from design of the phone,or i broke them in some way.
My phone is global version,TA-1021,my english is bad sorry for that,i hope you understand me.

Normal, my ta-1033 is equal.
It's a build default.

You mean you can see an very small light from these buttons too right ? I barely see the light without case that cover those buttons from scratches & dust particles.

Yes! I have a transparent cover, and I have the same "issue".
It's normal, don't worry about it.
