No sensor, just your imagination, scratch or build defect.
I dont mention that it is sensor, but what is this? please see in the angle to your apparatus and you will see it, maybe something that producers did for future uses? just take a look!

I have check on my girlfriend's TouchHD and there is....... NOTHING!
There is nothing there. Your phone might have some kind of minor manufacturing flaw that makes you think there is something there. I have had my HD for a year and have never heard of anything being there. I looked at it from all angles, and compared it to the right side. My phone shows nothing. Both the left and the right side look the same.
Thank you all for your attempts, but I will tru to put pic of it (if camera will capture it), and maybe than you can explain me this place usebility. Will try to give a pix on monday!!!

I highly doubt there's anything. I've recently opened up my phone to replace the screen and had to mess around in there with the camera/speaker/light sensor and there was nothing else.
Please see attached photoes, can anybody explain this window dedication? Waiting for your replyes.
looks like a air bubble under the screen protector.
Oh common guys, it is not bubble, not scratch, please look on top of htc logo untill calldynamic, this thing placed between them. Mayby mine is special, super-assembled!!!
ok, i was doubtful but i checked anyway and couldnt see anything, then i saw your pics and thought id give it another try and nope, nada, then i figured id pull it to bits and have a gander and inside and still nothing.
Whilst this was slightly entertaining im affraid to say you have probably got a bubble under the first layer of screen.
That is the most likely explination, the chances you have a one off device that no one else has which has some mystical new sensor is so small you'd be better off putting your life savings and the money you made selling your house on the lottery in the hope you'll hit the big one!
Ok, if accept the version that it is bubble under first layer, can you explain why this bubble has so right geometric forms? The guy next to me has an IPhone, and even him thought that it is porximity sensor like his apple has. Strange and Mistyc!!!
I agree that the shape is very geometrical, and I can understand how it would make you think there is something special there. It is unique, but I still don't think it's related to any functions or features the phone has. Look at the letters "htc". You have a slight frame around each letter that is the same shade/color as the "window" you are referring to. My "htc" letters have no such frame around them. The black of the phone comes up directly to where the white letters start.
So, I think it's some kind of strange manufacturing effect.
I'll even attach the service manual for you to look at.
Download service manual here
To be truthfully honest I thought you were seeing things until you posted your 3 pics. Yes, it does look geometrical in shape, but I can assure you that this is not a sensor, button or anything else intended by HTC. As stated by others previously is looks like a flaw in some way, either on the device itself or caused by the skin protector. If you take your device to any retail shop and compare it with another HD this may ease your concerns and I'm sure the staff in the shop would also say as everyone else here has.
Absolutely agree with htc letter, before your post i don't even see this feat, well, i think i should agree with that this window has no any function. Besides i saw off. manual, no-nothing. OK, waiting for another variants of reply.

Well, first of all device was bought not in EU, second, in my country very hard to find even person who owns device, too much expensive for our market, i'm even not talking about shops to compare my apparatus with others. By the way, does anybody know, whether in this forum chats somebody from HTC. i would asked him directly.

Looks like something trapped under the screen protector, did you peel it back and check?

got c50 nexus 7 should i get a replacement?

Hey all I ordered met nexus 7 about 2 weeks ago and I love it. I do have a slight screen lift issue thought. Not as bad as others that had posted but enough to bother me.
I was reading up on the forums and how people were saying there different models (date manufactured). So I decide to see what number I got. I thought I would at least have a c60 or c70 model but I noticed a c50. I thought c60 was the earliest model?
What do u guys suggest? I during?I'd noticed that when I got it that there was 2 things of security tape on it (very overlapping so it only looked like 1but there was 2) and that there was 2 fingerprints on the copper heat tape next to the battery.
Does anyone know if the c80 fixed the screen issue for sure. Also how is Asus return work out. I had to RMA a bad motherboard to them before and it was the worse RMA I ever did.
Thanks guys and lmk what u think
Hi mate,
Well if it's got screen lift, that's a good enough reason to send it back. There is always the chance that you will shatter the screen if you tighten the screws up......
Yeah, I thought that C60 was the earliest model that they made. Obviously not. Looks like you were unlucky getting such an early model, this late on.
There are still some problems with the C80 lot, but not as common as they were in the previous versions. Can't you return it to the shop, or Google that you bought it from? You'll still be within the 28 days return. I was out and they still accepted it back without any hassle (Tesco UK)
I got a c5 model as well. I've had it for almost 3 weeks now. Was pretty upset at first when I got it because it was actually my second replacement from the Google store. Everything was fine until recently when I started to have the touch screen issues and the headphone out only outputs the right channel. Contacted Google again a couple days ago and they are gonna let me swap it again.
At this point, I don't care when it was made as long as it has no issues (major issues).

Getting a newer SSN doesn't guarantee that you won't have issues. The screen lift is minor compared to screen flicker, bad pixels, etc.

The first part is correct. Although it seems that many units have been opened and checked for obvious cases of separation, nothing has been done to solve the problem. ASUS has been rather curiously leaving screws off the left side recently, but that has not been a permanent solution for most users.
As for your statement that screen lift is minor, I don't know why you're still spreading this misinformation.
By no means is it guaranteed to cause problems, but there have been many reports of lifted displays cracking during normal use. Although the likelihood of this happening is unclear at this point, we know for a fact that this flaw has potentially serious consequences, and that ASUS will not accept responsibility under any circumstances.
Cracked screen... will ASUS fix it?
Nexus 7 screen cracks easily
The "it's broken already" thread
I have not heard anything about Google's coverage of this issue, aside from erica_renee's screen cracking right away, seen here:
http://forum.xda-developers.com/showthread.php?t=1858400&page=4
They handled her case generously, but that was a freshly unboxed unit so maybe they made an exception. Also, she said that her unit didn't even have lift, so I don't mean to imply that the cause of her broken glass was screen lift. It could have been an anomaly rather than a widespread flaw.
Although it would be useful to know definitively how Google intends to handle a lifted screen cracking within warranty, it's infinitely more likely that you'll be taken care of if you purchased from the Play store. I think that if your lift is truly minor and you're going to be dealing with Google as a possible safety net, tolerating this flaw is an acceptable risk. But you'll have to make up your own mind.

Those links are focused and informative. Posting any more than three would look cluttered.
But since you asked nicely, here are some more links worth considering.

I went on my own mission to find a perfectly flat screen. After the 5th N7 at various Walmart and staples I've came to the conclusion no N7 will be perfectly flat they all have a slight lift towards the center one the left side.

As everyone can see, this is the third time you've confronted me like this. And your tone has been increasingly hostile.
Ironically, this grudge you're nursing began with me helping you to inspect your own unit. You discovered that you have screen lift thanks to my help, and you've been popping up to berate me ever since. I don't know where this hostility came from, since our first exchange spanned the course of a single page and I was nothing but friendly throughout. Here is the final post of our first interaction:
pxlitup said:
Don't mistake my motives. I'm glad that you are happy with your purchase.
I'm only notifying you of the possible risks, which I believe warrant a mention since they do exceed the concerns of normal wear and tear.
Remember that internationally this tablet can cost much more than you or I paid for it. It's important for people to be able to make an informed decision about whether or not to purchase it, and you being honest about your screen inspection, even though you think I'm being OCD, was very helpful in that regard. You would be surprised at how many people believe facts are subjective when tech company loyalties come into play.
Hopefully your tablets won't give you any trouble. Your lift is certainly not as severe as many of the units from July that are still going strong.

I don't know how we got here, but here we are. If you do decide to continue doing this, I will report you.
For anyone interested, here is the photo you originally uploaded to prove that your screen was flawless. The very minor separation has been circled.
And here is a record of your budding fascination with me, pulling my pigtails and so forth. You can edit your posts if you want, but it's all there.
Just to clarify, having c50 or c60 doesn't mean that it's going to be faulty. My third n7 (first two were f...) is c60 and flawless so far. Screen is perfectly aligned and I don't have any ghosting nor other problems.
My 16gb N7 is also C6O & it is almost perfect. No dead pixels & only the extremely tiniest lift only visible if viewed at just the right angle. Not even an issue. My 8gb is also a C6O & no lift or problems

How to test if your S-pen is flawed / erratic or not.

Some weird S-pen behavior was brought up in this thread:
http://forum.xda-developers.com/showthread.php?t=1935657&page=3
At first I was not aware (like most of us?) that my pen too suffered from these flaws but I decided to try it and discovered that I too could indeed replicate the "errors" mentioned.
I think it is time we bring some light into this matter so here is how to test if your phones S-pen behaves erratically or not:
- Go to your dialpad
- Enter *#0*#
- Press 'Wacom Test'
- Draw long diagonal lines from upper left to lower right. Also try drawing in the lower right (and left) corners.
- Press and hold the pen-button while pressing and holding pen at screen to take a screen-shot.
- Result is stored in Storage/SDCard0/Pictures/ScreenShots/
My belief is that all phones share this "flaw" and that those saying they don't, simply haven't tested it properly. But this is just my guess and I may be wrong about this.
Anyway, please give it a try and report your results here.
Here is a link to an image showing the problem:

Oh there is a whole bunch of waves on the right side of your screen-shot. They are very subtle, but they are there.
They will become more visible if you draw longer lines and at slightly more than 45 degree angle.
I went to a mall today and tried their Note II and just as I expected it had the very same "flaw" when I tested it.
So I believe the people claiming not to have this issue, are either not doing the testing the same way as described, or simply not noticing the flaws.
It is not a big deal for most users of course.
But for people doing a lot of drawing it can be quite bothersome, since these "flaws" will affect all kinds of drawing in a subtle way, not just when drawing diagonal lines.

It could just be that your hand is not drawing straight. Remember its plastic on glass, not much friction. Try doing this with a ruler and see if its any different.

I think the problem lies in the wacom pen. I noticed a slight displacement of the tip in relation to the pen. The slower it gets the more dramatic the waves.

The tip may seem a bit wonky, but I am now pretty sure the waves comes from some kind of (magnetic or otherwise?) "interference".
As I went to the mall to try out their S-pen, I noticed a HUGE wave-bulge in the middle of the screen! First I thought that some customers had just poked the screen a bit too hard, but then I flipped the device over and discovered an electronic(magnetic?) anti-theft-gadget attached to the exact opposite side of the device, where that big wave-bulge (looking like an onion) appeared when drawing.
I even took photo-proof of this. I'll try to upload them here if I can find the time.
Here are photos from the mall.
One photo shows interference in the shape of an onion.
The other photo shows the security-device on the back causing the bulgy waves.
Maybe this will help someone with more technical knowledge deduce what causes the "normal" smaller waves on all our phones?

Hmm, Wacom active digitizer pens are affected by magnets so it's not surprising that large bulge thing happened in the store.
Don't know if it's the same thing with the Note2 screens though. My Note1 has a similar issue in the very top left corner (you can't draw straight lines there).
Supposedly even metal parts near the screen can actually affect the writing ability of the Wacom digitizer but the driver is supposed to compensate for that. Perhaps the driver isn't calibrated as well as it should be.

Due to religious events, I was busy, but I can confirm that the fault is with our S-Pen, I went to Phones4U and tested their device, and used their pen on my phone which did not produce the same lines as my pen does. I will upload photo's later. I will contact Samsung on Monday.

Try AMOLED Burn-in Fixer on the Play Store. How it works is by leveling out the amount of wear on the OLEDs making up the screen. I've not personally used it, and don't know if it actually works, but it's free to try. However, if that app doesn't work, only a screen replacement will fix the problem, as burn-in is permanent on an AMOLED display.

Any suggestions?
Not really, only because your needs will differ from mine. For example, the 5" screen is too small for me, so I went with a Nexus 6. However, the Nexus line is pure Android and may not appeal to everyone. You're simply going to have to do some research in what you want in a smartphone.
Did software helped?

Difference in power button bet. initial & recent lot

I just happened to find this Japanese article saying Z5P's has different power button areas between initial (or early) lot and recent lot. I can't understand everything but the article basically says the upper is the recent one.
Does anyone have Z5P with the upper one?

I can guarantee you that it's a Z5P on the pic. The metal is glossy and seems to catch fingerprints easily. Z5 has a more matte finish.
You're right, Z5P is not available in the US, then my guess is as good as yours.
Seems like it might be to do with issues they've had with the touch sensor working properly on the first revision because of the slightly recessed button. Now it's flush so there is better contact. I haven't seen that revised version yet though, but I'll keep an eye out.

I gotta be honest, it looks cheaper than before like that, but I also would to know the Rev number of that batch.
